How I do it: 3-Suture robotic pyeloplasty: Step-by-step technique.

Robot-assisted pyeloplasty is now a gold standard in the treatment of pediatric ureteropelvic junction obstruction. We describe a standardized "3-suture" technique designed to facilitate the pyelo-ureteral anastomosis. We used this technique in 65 paediatric patients aged 3-17 years. Early major complications (Clavien-Dindo grade III) occurred in 3 patients (4.6%). The median operative time was 150 min. Surgical success was achieved in 96% of cases at a median follow-up of 9.5 months. This 3-suture approach offers a highly reproducible method for robotic pyeloplasty, facilitating accurate anatomical reconstruction with excellent surgical outcomes.

Comparison of conventional and micro-surgical techniques for gingival recession using collagen matrix: Randomised controlled split-mouth clinical trial.

BACKGROUND: The present study aimed to determine the effectiveness of the microsurgical approach in treating gingival recession with collagen matrix by comparing it with Conventional surgery in terms of clinical and patient-centered outcomes. METHODS: A total of 29 patients with bilateral gingival recession in the maxillary canine and/or premolar region were selected. After randomisation, bilateral recession sites were grouped into the test group (Microsurgery under 3.5 X magnification) and the control group (Conventional surgery). All the clinical and patient-reported parameters were recorded at baseline, 1, 3 and 6 months. RESULTS: Both groups showed statistically significant differences in terms of reduction in gingival recession height (GRH), gingival recession width (GRW), clinical attachment level gain (CAL gain), increase in keratinized tissue thickness (KTT) and keratinized tissue width (KTW) after 6 months. But intergroup comparison showed no significant difference in terms of clinical parameters. The only significant difference was noted in terms of patient-centred parameters (Patient satisfactory score, Hypersensitivity score, Root aesthetic scores), which favoured the microsurgical group. CONCLUSIONS: Both groups demonstrated comparable clinical improvement; However, Patient-centred parameters were significantly better with the Microsurgical approach. Selection of the surgical approach should balance patient needs with practical considerations like cost, time, and clinician proficiency.

Stapled versus hand-sewn intestinal anastomosis in pediatric surgery: A systematic review and meta-analysis.

BACKGROUND: Intestinal anastomosis is a core procedure in pediatric gastrointestinal surgery, performed for conditions such as necrotizing enterocolitis, intestinal atresia, Hirschsprung's disease, and inflammatory bowel disease. Although stapled anastomosis (SA) may improve operative efficiency, its safety and effectiveness compared with hand-sewn anastomosis (HA) in children remain uncertain. This meta-analysis compared clinical outcomes of SA and HA in pediatric patients. METHODS: The study followed PRISMA guidelines and was prospectively registered in PROSPERO (CRD420251177257). A systematic search of PubMed, Dimensions, and the Cochrane Library was conducted through June 2025. Studies including children under 7 years undergoing intestinal SA or HA were eligible. Two reviewers independently performed study selection, data extraction, and risk-of-bias assessment using ROB 2 and ROBINS-I tools. Statistical analysis was conducted using Comprehensive Meta-Analysis software (v3) with a random-effects model. RESULTS: Eleven studies involving 903 patients met inclusion criteria, including two randomized controlled trials. Of these, 333 patients underwent SA and 570 underwent HA. SA was associated with significantly shorter operative time (mean difference [MD] = -19.26 min; 95% CI: -24.24 to -14.28; p < 0.001) and earlier initiation of oral feeding (MD = -2.32 days; 95% CI: -3.78 to -0.86; p = 0.002). No significant differences were found in anastomotic leakage, stricture formation, reoperation rate, or length of hospital stay. CONCLUSIONS: Stapled anastomosis appears as safe as hand-sewn techniques in pediatric intestinal surgery while offering shorter operative duration and faster postoperative feeding recovery. Selective use of stapled techniques is supported when anatomically feasible, though further multicenter randomized trials are needed.

A modified stomal construction technique to reduce incidence of stomal stenosis in continent catheterizable channels.

BACKGROUND: Antegrade continence enema (ACE) and catheterizable bladder channel (Mitrofanoff) procedures are routinely performed in pediatric urology patients diagnosed with a neurogenic bladder and bowel. Stomal stenosis is a common surgical complication of these procedures, occurring in approximately 10-30% of stomas. Our frustration with this complication prompted us to modify our suturing technique during stomal construction to attempt to decrease the incidence of stomal stenosis. METHODS: We compared the rates of stomal stenosis between patients with neurogenic bladder who underwent the creation of an ACE or Mitrofanoff channel using the historical techniques (prior to April 2018) versus the current technique (from April 2018 to December 2020). Our current technique for stoma creation consists of suturing full thickness bowel to only the dermal layer of the skin using interrupted 5-0 polydioxanone interrupted sutures with the knots buried. Statistics were performed using Fisher's exact t-test, with p-values <0.05 considered significant. RESULTS: There were no significant differences in demographics between patients in the 2 cohorts. Stomal stenosis occurred in 25 of 98 stomas (25.5%) after undergoing either an ACE or Mitrofanoff procedure using the historical techniques, with a median patient follow-up of 122.6 months for ACE cohort and 165.8 for Mitrofanoff cohort. The incidence of stomal stenosis was significantly decreased in the current technique, with one of the 31 stomas (3.2%) experiencing stenosis (p = 0.022), with a median follow-up of 78.4 months for ACE cohort, and 66.5 months for Mitrofanoff cohort. These follow-up durations exceed the upper limits of time-to-stenosis in the historical stomas. Stomas in the current cohort have a minimum follow-up of 4.5 years and a maximum follow-up of 7 years. CONCLUSIONS: Our current suturing technique has significantly reduced the incidence of stomal stenosis in our patients. The technique is straightforward and flexible and can be applied to any stoma placed in any position. Only one of the patients with stomas created with the current suturing technique have developed stomal stenosis, with follow-up exceeding the median time to development of stenosis of our historical cohort.

The transverse preputial onlay island flap: A reliable option for repair of small-glans hypospadias.

BACKGROUND: The Transverse Preputial Onlay Island Flap (TPOIF) technique is frequently used in cases with mild chordee and small glans. This study's objective was to evaluate the surgical outcomes of this technique at our center. MATERIALS AND METHODS: This study consisted of hypospadias patients diagnosed with small glans (diameter <14 mm) and mild chordee (<30&#xb0;), underwent TPOIF urethroplasty. RESULTS: A total of 64 cases were included in this study. The mean glans diameter was 10.6 mm. The complication rate was 9.4 %. CONCLUSIONS: The TPOIF technique provides encouraging results for treating hypospadias with small glans, though larger studies are needed.

Indications, Techniques and Complications Associated With Pterygoid Implants: A Systematic Review and Meta-Analysis.

BACKGROUND AND OBJECTIVES: Pterygoid implants represent a graftless option for rehabilitation of patients with posterior maxillary atrophy, engaging the dense cortical bone of the pterygomaxillary complex. Despite clinical growth, a comprehensive synthesis of indications, surgical techniques, and complications is lacking. This review evaluated the prevalence of complications, implant survival rates, and marginal bone loss (MBL) associated with pterygoid implant placement. METHODS: The reporting of this review follows PRISMA 2020 guidelines. Six electronic databases (PubMed, Ovid, Scopus, WoS, CENTRAL, and Dentistry & Oral Sciences Source) were searched from 1 January 2020 to 31 December 2025. Included criteria comprised randomized and non-randomized clinical studies reporting outcomes of pterygoid implants (&#x2265;&#x2009;13&#x2009;mm) in adult patients with posterior maxillary atrophy (minimum 10 implants). Risk of bias was assessed using JBI critical appraisal checklists. Proportions were pooled using the Freeman-Tukey double arcsine transformation under a random-effects model. Certainty of evidence was assessed using GRADE. RESULTS: Seventeen studies reporting 846 patients and 1915 pterygoid implants were included. The pooled survival rate was 97.9% (95% CI: 97.1%-98.6%; I2&#x2009;=&#x2009;0%; 14 studies) and the overall failure rate was 2.1% (95% CI: 1.4%-3.0%). Early failure rate was 0.9% (95% CI: 0.0%-3.0%; I2&#x2009;=&#x2009;59.5%). Late failure and MBL were summarized narratively. Certainty of evidence was low to very low. CONCLUSIONS: Pterygoid implants demonstrate excellent survival (97.9%) and low failure rates (2.1%), primarily early, supporting their reliability as a graftless solution for posterior maxillary atrophy. Complications appear infrequent though heterogeneously reported. Low evidence certainty necessitates prospective studies with standardized outcome reporting.

Sutureless versus renorrhaphy in robot-assisted off-clamp partial nephrectomy: a systematic review and meta-analysis.

BACKGROUND: The necessity of routine parenchymal renorrhaphy during off-clamp robot-assisted partial nephrectomy (RAPN) remains uncertain. This study aimed to compare perioperative, functional, safety, and oncological outcomes between sutureless and conventional renorrhaphy. METHODS: We conducted a systematic review and meta-analysis following PRISMA 2020 guidelines. Comparative studies evaluating sutureless versus conventional renorrhaphy during purely off-clamp RAPN were included. Trifecta achievement was the primary outcome. Random-effects models were used for pooled analyses, with subgroup analysis according to study design. RESULTS: Four studies involving 787 patients, including one randomized controlled trial (RCT) and three propensity score-matched (PSM) studies, were included. The overall pooled estimate showed no statistically significant difference in Trifecta achievement (RR 1.17, 95% CI 0.97-1.41), with substantial heterogeneity (I&#xb2; = 86.5%). The PSM studies favored the sutureless approach (RR 1.26, 95% CI 1.05-1.52), whereas the RCT yielded an RR of 0.97 (95% CI 0.92-1.04) and met the prespecified noninferiority criterion without demonstrating superiority. The sutureless approach was associated with a smaller perioperative eGFR decline (MD&#x2009;-&#x2009;3.89, 95% CI&#x2009;-&#x2009;6.16 to -&#x2009;1.62), while no significant difference was observed in eGFR at 3 months. No statistically significant differences were identified in major complications, blood transfusion, or positive surgical margins; urinary and vascular complications were sparsely reported. CONCLUSIONS: In selected patients undergoing purely off-clamp RAPN, randomized evidence supports the noninferiority of a strategy that omits routine parenchymal renorrhaphy while permitting clinically necessary selective repair, but does not demonstrate superiority. Favorable estimates from PSM studies remain vulnerable to intraoperative treatment-selection bias. Current evidence is insufficient to determine whether omission of renorrhaphy affects urinary complications, long-term renal function, or oncological outcomes. REGISTRATION: This systematic review was registered prospectively in PROSPERO (CRD420261435995).

Surgical treatment of schwannomas around the tarsal tunnel: a case series of 40 patients and systematic review of the literature.

OBJECTIVE: Schwannomas in the tibial, plantar, or medial calcaneal nerves around the ankle can mimic symptoms of tarsal tunnel syndrome. Outcomes after resection of schwannomas from these nerves have mainly been reported in case reports. The objectives of this study were to investigate the presentation and results for resection of schwannomas around the tarsal tunnel in a large case series and systematically review the currently available literature. METHODS: Data from 40 patients (27 sporadic and 13 schwannomatosis cases) treated at 2 centers were retrospectively analyzed for preoperative type and duration of symptoms, schwannoma size at presentation, and outcome after resection. The following different locations around the ankle were compared: proximal to the tarsal tunnel (PTT), at the tarsal tunnel (ATT), and distal to the tarsal tunnel (DTT). The severity of symptoms was categorized in increasing order for pain only on touch, during load-bearing activities, and symptoms also at rest. Surgical outcome was assessed based on pain relief and occurrence of complications. The systematic literature review was performed using a PubMed and Embase search. RESULTS: All but 1 patient presented with pain, local at the ankle, or neuropathic pain during weight-bearing activities (13/40, 32.5%). More than half of the patients also experienced symptoms at rest (52.5%). In 14 cases, the schwannoma was located PTT, in 17 cases ATT, and in 9 cases DTT in the plantar nerves. There were no significant differences in size and symptom duration at presentation for the different locations. Tumor size did not correlate with symptom severity. Outcomes after resection were excellent, with complete pain relief in all but 1 patient (97.0%). Complications included wound infection (5%) and temporary decreased sensation on the heel (7.5%). A review of 44 previously reported cases also frequently showed complete pain relief after resection. CONCLUSIONS: The results of this study show that schwannomas around the tarsal tunnel often present with severe pain symptoms, even if the lesion is still relatively small. Resection frequently results in excellent pain relief. During surgery, it may not be necessary to open the entire length of the tarsal tunnel, thereby limiting the size of the incision, especially in schwannomas located proximally or distally to the tarsal tunnel.

Delphi study robot consenso: Strategies for the implementation of robotic surgery in general surgery in the Spanish hospital network.

INTRODUCTION: The implementation of robotic surgery in public hospitals presents multiple logistical, educational, and organizational challenges. In the absence of unified guidelines, a national consensus is required to optimize its safe and efficient adoption. This study aimed to establish a set of consensus-based and measurable recommendations for the implementation of robotic surgery programs in hospitals within the Spanish National Health System, based on the experience of centres with established robotic programs and intended to serve as guidance for hospitals that are initiating or planning their implementation. METHODS: A national Delphi study was conducted with the participation of robotic surgery experts from 26 public hospitals. The expert panel was composed exclusively of digestive surgeons with experience in robotic surgery. Three iterative rounds of expert panel evaluation were conducted between March 2024 and March 2025. The questions were grouped into five thematic blocks. Consensus was defined as an agreement level of &#x2265;66.7%. Kendall's W coefficient was used to assess concordance. RESULTS: High levels of consensus were achieved on key aspects related to infrastructure, structured training, cost evaluation, and quality assurance mechanisms. Areas of disagreement were also identified, such as the need for a dedicated anaesthesiologist, purchase of accessory instruments during the initial phase, and official accreditation pathways. CONCLUSIONS: This study provides a guideline for developing a national robotic surgery strategy focused on patient safety, program sustainability, and standardized training of surgical teams. These recommendations can guide hospitals at different stages of robotic technology adoption. Given that the consensus was reached from an exclusively surgical perspective, the recommendations focus on patient safety, program sustainability, and standardized training of the surgical team, and should be interpreted in an adaptable manner according to each centre's context, case volume, and available resources.

Prognostic Value of Frailty in Aortic Surgery: A Systematic Review and Meta-Analysis Comparing Frailty Assessment Tools.

BACKGROUND: Frailty is increasingly recognized as an important determinant of outcomes after aortic vascular surgery, but assessment methods vary substantially and the optimal tool for risk stratification remains uncertain. This systematic review and meta-analysis evaluated the prognostic value of preoperative frailty and compared the predictive performance of different frailty instruments in aortic surgery. METHODS: PubMed, Embase, and Cochrane Library were searched from inception to April 27, 2026. Eligible studies included patients undergoing open, endovascular, or hybrid aortic procedures involving abdominal, thoracic, thoracoabdominal, arch, and proximal aortic diseases, including aneurysms and dissections, assessed frailty preoperatively, and reported postoperative outcomes. RESULTS: Thirty studies comprising 419,459 patients were included. Frailty was associated with higher early mortality (odds ratio [OR] 2.20; 95% confidence interval [CI] 1.54-3.14) and late mortality (hazard ratio 2.18; 95% CI 1.64-2.90). Frail patients also had increased risks of major complications (OR 2.52; 95% CI 1.22-5.19), acute kidney injury (OR 1.64; 95% CI 1.34-2.02), and nonhome discharge (OR 5.50; 95% CI 3.05-9.92). Associations were consistent across surgical approaches and aortic segments. Judgment-based or phenotype-like tools yielded higher effect estimates than deficit-accumulation indices, although differences were not statistically significant; among index-based tools, Modified Frailty Index (mFI)-11 outperformed mFI-5. CONCLUSION: Preoperative frailty strongly predicts mortality, morbidity, and loss of functional independence after open, endovascular, and hybrid aortic surgery across different aortic segments and pathologies, including aneurysmal and dissecting aortic disease. Routine frailty assessment may improve risk stratification and perioperative decision-making.

Temporal evolution of minimally invasive pediatric urolithiasis treatment over 30 years.

Urolithiasis in children has increased substantially over the past 30 years, and surgical management maintains an important role in treatment. Technological advances such as lasers and miniaturization have broadened treatment options, and researchers investigate the best indications for each procedure. The aim was to identify publication trends in the field and explore reasons why Extracorporeal Shockwave Lithotripsy is being gradually less applied in the treatment of pediatric urolithiasis. A Reverse Systematic Review of the literature was conducted regarding the surgical treatment of urolithiasis in children. Five databases were screened, gathering all articles from inception that were evaluated in systematic reviews. We examined 123 publications, 197 reports, and 15,878 procedures, consisting of the largest studied population in the field. There was an increasing number of publications, although in progressively less prestigious journals. The number of studies on miniaturized percutaneous techniques and flexible ureteroscopy has increased closely with the rise in popularity of these procedures worldwide, mainly driven by studies from Asia, Europe, and North America. A trend of self-renewed interest is fueled by technological innovation and has led to fewer publications on Extracorporeal Shockwave Lithotripsy over the years. This review highlights the fact that, despite positive results in recent studies, the low popularity of ESWL within the scientific community is driving a decline in the technique's indications. Moreover, based on the findings of this study, key research priorities include continued reporting of high-quality outcomes, and technological progress in ESWL would contribute meaningfully to the field.

Meniscal preservation in the age of biologics: toward a quantitative decision algorithm for personalized repair.

BACKGROUND: Despite advances in arthroscopic repair and biologic augmentation, surgical indication for meniscal tears remains heterogeneous. No standardized framework currently integrates biomechanical, clinical, and biological determinants to guide repair versus resection. PURPOSE: To develop a quantitative decision model-the Meniscal Preservation Score (MPS)-that unifies biomechanical and biological evidence to stratify reparability potential and standardize treatment selection in meniscal surgery. METHODS: A systematic evidence synthesis conducted in accordance with PRISMA 2020 reporting standards of studies published from 2000 to 2025 in PubMed, Embase, and Scopus identified key determinants of meniscal healing. Five consistent predictors-patient age, vascularity, tear morphology, associated pathology, and activity profile-were weighted through a two-round modified Delphi consensus among ten experienced knee surgeons. The resulting 0-9-point MPS was incorporated into a stepwise decision tree linking lesion morphology, biological context, and surgical strategy. Conceptual validation used 50 simulated cases and a retrospective cohort of 45 patients to test agreement between algorithm recommendations and expert surgical decisions. RESULTS: The MPS achieved 86% concordance with expert judgment in simulation and 84% agreement in clinical validation. In this retrospective exploratory cohort, cases in which surgical management was concordant with MPS recommendations demonstrated higher mean IKDC scores at 24&#xa0;months and lower observed reoperation rates. These findings should be interpreted as associative rather than causal, as treatment allocation was not controlled and discordant cases may have represented inherently more complex pathology. CONCLUSION: The MPS represents an evidence-informed decision-support framework designed to systematize reparability assessment. While exploratory analyses suggest structural coherence with expert reasoning, prospective implementation and external validation are required before clinical adoption as a predictive tool. LEVEL OF EVIDENCE: conceptual model with exploratory validation.

Contemporary surgical decision-making for hallux valgus and hallux rigidus in Switzerland: A national cross-sectional survey using standardized clinical scenarios.

BACKGROUND: Surgical management of hallux valgus and hallux rigidus is influenced by deformity severity, surgeon training, and evolving techniques. Previous surveys in Australia (2012), Switzerland (2015), and Israel (2023) using identical hypothetical cases demonstrated marked regional differences and a recent rise in minimally invasive Chevron-Akin (MICA). Whether these advances have altered contemporary Swiss practice remains unclear. METHODS: An electronic survey replicating the original questionnaire was distributed to members of the Swiss Foot and Ankle Society. Three standardized clinical cases were presented: mild hallux valgus, severe hallux valgus, and hallux valgus et rigidus. Respondents selected nonoperative versus operative management and specified procedures and fixation methods. Demographics, subspecialty training, and surgical volume were recorded. Current results were compared with prior Swiss data to assess temporal change. RESULTS: Eighty surgeons completed the survey (94% foot and ankle specialists). For mild hallux valgus, 87.7% recommended surgery; Scarf osteotomy remained most common (49.4%), followed by Chevron (21.0%) and Minimally Invasive Hallux Valgus correction (14.8%). Minimally Invasive adopters were predominantly mid-career (83% aged 41-50), high-volume surgeons. For severe hallux valgus, 95.1% favoured surgery; MTPJ arthrodesis was preferred (50.6% isolated; 11.1% with Lapidus), while Minimally Invasive Hallux Valgus correction was rarely chosen (2.5%). In hallux valgus et rigidus, 96% selected MTPJ fusion, most commonly plate-and-screw fixation (45.1%). Compared with 2015, fixation strategies evolved, yet procedure selection remained largely unchanged. CONCLUSION: Despite global expansion of minimally invasive bunion surgery, Swiss surgeons continue to favour established open techniques, particularly Scarf osteotomy and fusion-based strategies. Adoption of MIS remains limited and concentrated among high-volume, mid-career specialists, indicating a cautious national diffusion pattern. LEVEL OF EVIDENCE: IV, survey study.

Surgical management of esophageal atresia with tracheoesophageal fistula in extremely low birth weight neonates: A systematic review.

BACKGROUND: Surgical management of esophageal atresia/tracheoesophageal fistula (EA/TEF) in extremely low birth weight (ELBW) neonates remains challenging and controversial. This study systematically reviews surgical strategies and outcomes in this population. METHODS: Following PRISMA guidelines, Cochrane, Embase, MEDLINE, Scopus, and Web of Science (2004-2024) were searched in February 2025 for studies on surgical management of ELBW neonates with EA/TEF (PROSPERO CRD42025636228). Fatal chromosomal abnormalities were excluded. Demographics, comorbidities, surgical techniques, and complications were analyzed descriptively. Risk of bias was assessed. RESULTS: Eleven publications (five case reports and six case series) comprising 30 patients (Gross type B/C = 1/29) met the eligibility criteria. Mean gestational age was 28.1 (23-34) weeks, and mean birth weight was 760.4 (422-995) g. Twelve primary repairs (PR) and 18 delayed primary repairs (DPR) were performed, including staged repair (n = 11), lower esophageal banding (n = 4), and other techniques (n = 3). Postoperatively, four anastomotic leaks were managed conservatively, six strictures and one recurrent TEF required endoscopic intervention, three fundoplications and two aortopexies were reported (follow-up: 1-198 months, n = 19). Overall mortality was 30% (PR: 8.3%; DPR: 44.4%). Mortality was 60% among neonates with major congenital heart defects (CHD) and 40% among those with VACTERL association. EA/TEF-related complications contributed to 33.3% of deaths. CONCLUSIONS: Mortality in this cohort remains high, particularly with major CHD, and is largely unrelated to EA/TEF-specific complications. In selected cases, PR appears feasible as an alternative to DPR, although conclusions are limited by the small sample size and heterogeneous studies.

Transverse Tibial Transport for Limb Salvage in Ischemic Lower Extremity Disease: Technique, Mechanisms, and Clinical Outcomes-A Systematic Review.

Transverse tibial transport (TTT) is a surgical technique derived from Ilizarov's distraction osteogenesis principles that stimulates angiogenesis and microcirculatory regeneration in the ischemic lower limb without directly manipulating macrovascular anatomy. By creating a proximal tibial cortical bone window and distracting it transversely using an external fixator, TTT triggers converging cascades of growth factor release, endothelial progenitor cell mobilization, and immunomodulation that translate into improved distal limb perfusion and wound healing. Combined TTT plus endovascular therapy improves amputation-free survival versus endovascular therapy alone. Prospective randomized trials and standardized international protocols are needed to consolidate TTT's role in multidisciplinary limb salvage pathways.

The wider erection angle in hypospadias: A neglected feature affecting surgical outcomes.

INTRODUCTION: Penile curvature often accompanies hypospadias, and numerous techniques have been described for its correction; however, in some cases, an abnormal erection angle may also be present, further exacerbating the perception of curvature. OBJECTIVE: This study investigates the significance of the erection angle in hypospadias cases and its correlation with the severity of the anomaly. STUDY DESIGN: A retrospective analysis of intraoperative photographs of hypospadias cases operated between 2019 and 2023 was performed. Erection angle was measured with a digital goniometer during a full artificial erection. Erection angles in proximal and distal hypospadias cases were analyzed and compared to data from Kinsey's subgroups representing healthy male erection angles. RESULTS: This study involved images of 68 patients, with 31 having proximal and 37 distal hypospadias. The median age of the whole group was 11 months (6-156, IQR 9). Median erection angle was 91 (63-119, IQR 11) for distal cases, whereas it was 96 (75-138, IQR 21) for proximal cases. The difference was statistically significant (p = 0.009). The erection angle distribution in our cohort, including both proximal and distal hypospadias cases, skewed toward wider angles, highlighting a distinct pattern compared to data constituted by Kinsey and Sparling. DISCUSSION: Our findings indicate that the erection angle in hypospadias is significantly wider in proximal cases, suggesting a correlation between erection angle and severity of the hypospadias. While we acknowledge the limitation of comparing our prepubertal cohort with Kinsey's adult data, the absence of evidence suggesting significant post-pubertal changes in erection angle justifies this approach. Additionally, the use of digital images for angle assessment is not a standardized technique in hypospadias evaluation; these images were initially captured for curvature assessment. Despite these limitations, our study provides novel insights into seldom mentioned association with hypospadias - a wide erection angle, emphasizing the need for further research on its implications for surgical planning and long-term outcomes. CONCLUSION: This study introduces a wider erection angle as an additional characteristic of hypospadias particularly pronounced in proximal cases. To our knowledge, this is the first focused investigation on addressing this aspect of the condition. It emphasizes the need for further research on adults with wide post-repair erection angles to explore its long-term impact on sexual function and aesthetics.

Surgical outcomes and complications of fixation strategies for distal tibial fractures: a systematic review and network meta-analysis.

BACKGROUND: Multiple fixation options exist for distal tibial fractures, but the optimal approach remains controversial. Common techniques includeopen reduction and internal fixation(ORIF), minimally invasive plate osteosynthesis (MIPO), external fixation combined with limited open reduction and internal fixation (EF&#x2009;+&#x2009;LORIF), intramedullary nailing (IMN), and retrograde tibial nailing (RTN). METHODS: PubMed, Embase, Web of Science, and the Cochrane Library were searched through March 19, 2026. Network meta-analysis (R v4.5.1) assessed operation time, fracture healing time, malunion, delayed union/nonunion, and infection, reporting MDs or RRs with 95% CIs. RESULTS: Eleven randomized controlled trials and 18 cohort studies (2145 patients) were included. MIPO was associated with a longer operative time and a longer time to union than IMN-IP (MD&#x2009;=&#x2009;8.23, 95% CI 0.44-16.01; and MD&#x2009;=&#x2009;1.02, 95% CI 0.10-1.93, respectively). For malunion, ORIF had a lower risk than MIPO (RR&#x2009;=&#x2009;0.30, 95% CI 0.11-0.82), whereas MIPO had a higher risk than EF&#x2009;+&#x2009;LORIF (RR&#x2009;=&#x2009;3.26, 95% CI 1.08-9.80) and IMN-SP (RR&#x2009;=&#x2009;4.03, 95% CI 1.30-12.48). ORIF, EF&#x2009;+&#x2009;LORIF, and IMN-SP also showed lower malunion risk than IMN-IP. No significant differences were observed for delayed union and nonunion. Infection risk was generally higher with ORIF and MIPO than with several comparators, particularly EF&#x2009;+&#x2009;LORIF and intramedullary nailing-based strategies. CONCLUSIONS: No single strategy was consistently superior. Operation time and impaired union ( delayed union and nonunion) did not differ significantly among techniques. MIPO may be associated with longer time to union than IMN-IP and higher malunion risk than EF&#x2009;+&#x2009;LORIF and IMN-SP. Infection risk appeared higher with ORIF and MIPO in network estimates, although several comparisons remained uncertain. Findings should be interpreted in light of imprecision and study-level heterogeneity. PROTOCOL REGISTRATION: INPLASY2025120055.
