[Results of ureterocystoneostomy for inner urinary diversion in locally advanced prostate carcinoma].

Ureterneoimplantation (unilateral in 6 cases) was performed as palliative urinary diversion in 8 patients (age 64-81 years) due to locally advanced prostate cancer and bilateral ureteral obstruction (serum creatinine 2.1 to 9.8 mg. per dl.) between 1991 and 1995. In these cases the application of a double-J-catheter had failed or a percutaneous nephrostomy was refused. Postoperative time of survival (237 days, 2 patients still living for 20 and 21 months after therapy), mortality (1 of 8 patients), morbidity and time to hospital discharge (26 days) are compared to the results of the published retrospective investigations concerning percutaneous nephrostomy. The opportunity of a natural micturition without external urinary diversion could be gained for a longer period of time (5 and 20 months) in 2 of 3 patients. The other patients with in situ double-j-catheters were drained sufficiently by a suprapubic cystostomy (serum creatinine postoperatively 1.3 to 2.0 mg. per dl.). Bilateral ureterocystoneostomy being more invasive than unilateral diversion showed no benefits and was no more performed since 1991. Uretemeoimplantation with comparable postoperative results to percutaneus nephrostomy seems to be a sufficient therapeutic possibility in patients with natural micturition, repeated catheter complications, refusal or failure of alternative urinary diversion.

Traumatic posterior urethral disruptions in boys: experience with the perineal/perineal-transpubic approach in ten cases.

The management of traumatic posterior urethral disruption in children has ranged from primary realignment/repair to delayed urethroplasty. The operative approach may be perineal or transpubic; the advocates of either cite comparable outcome. The anatomic considerations in a child differ from the adult and the management is individualized. We present our experience with the perineal/perineal-transpubic approach in the management of traumatic posterior urethral disruptions in ten boys. A preliminary suprapubic cystostomy was followed by a delayed urethroplasty after comprehensive investigations to delineate the pathoanatomy of the disruption. The urethroplasty began with a perineal exposure and progressed to varying extents to achieve a satisfactory urethral anastomosis. Four cases of bulbomembranous disruption were repaired by perineal approach, whereas six cases of prostatomembranous disruption required a perineal-transpubic approach. Permutations of operative techniques (circumurethral mobilization, corporeal separation/urethral rerouting, pubectomy and omentoplasty) were used. The follow-up assessed micturition patterns, urinary continence and penile erections. At a mean follow-up of 5 years (1.5-12 years), all ten boys void in a good stream and are continent. All have normal penile erections, posture and gait. The paper discusses the rationale and outcome of our management.

Pitfalls in the management of newborn cloacas.

Clinicians caring for newborns with persistent cloaca face significant challenges in the newborn period. Avoiding key pitfalls during this time can have dramatic implications. We reviewed the medical records of 361 patients with cloaca operated on at our institution and analyzed sequelae that resulted from incorrect management in the newborn period. Of 361 patients, 282 underwent primary operations at our institution, and 79 patients were referred to us after a failed repair at other institutions. Pitfalls in management during the newborn period included the following: (1) Failure to recognize and manage hydrocolpos, which occurred in 46 patients. Of these, three patients developed pyocolpos (two progressed to vaginal perforation), and 43 suffered from persistent bilateral hydronephrosis, megaureters, recurrent urinary tract infections, persistent acidosis, or failure to thrive due to undrained hydrocolpos. They underwent unnecessary urinary drainage procedures (nephrostomy, ureterostomy, cystostomy, or vesicostomy) in the newborn period. When the vagina was finally decompressed, all of these symptoms disappeared. (2) Colostomy or vesicostomy problems, which occurred in 50 patients. These included incorrect placement of the colostomy (too distal, which interfered with the pull-through) in 24 and colostomy prolapse in 23. Incompletely diverting loop colostomies led to urinary tract infections in 49 patients. Vesicostomy prolapse occurred in three patients. (3) Clinical misdiagnosis, which occurred in 42 patients. Six were incorrectly diagnosed as "intersex" and 36 as "rectovaginal fistula." In this group only the rectum was repaired, and the patients were left with a urogenital sinus that required reoperation. Proper management of a newborn with cloaca includes drainage of a hydrocolpos, which avoids unnecessary urinary diversions and pyocolpos. Our preferred colostomy is one with separated stomas, adequate distal bowel for the pull-through, and use of a proper technique to avoid prolapse. Correct clinical diagnosis of cloaca avoids problems during the definitive repair.

Construction of female neourethra using a flipped anterior bladder wall tube.

Two cases in which a neourethra was constructed using a flipped anterior bladder wall tube are reported. One girl had lost her urethra secondary to a major urethrovaginal injury from blunt pelvic trauma, an in the other, the urethra had sloughed after cloacal reconstruction. Both patients had a closed bladder neck/proximal urethra and were received with a suprapubic cystostomy. A neourethra was constructed from an anterior bladder wall flap based distally. The flap was tubularized and flipped caudally to the site of the original external urethral meatus. Both girls are continent--one voids normally and the other is managed by clean intermittent catheterization. The flipped anterior bladder wall tube technique for construction of a female neourethra is suitable in patients with an absent urethra, particularly when the bladder neck/proximal urethra is closed.

Extracorporeal urinary bypass for malignant ureteral obstruction.

Extracorporeal urinary bypass was attempted in a patient with malignant ureteral obstruction. A nephrostomy was drained into the bladder by connecting the tube to a cystostomy catheter. This method made the patient free from a collecting bag without any significant complications. This method may improve the quality of life of patients with malignant ureteral obstruction, when their bladder is intact.

Urological complications in kidney transplantation: ureterocystostomy versus uretero-ureterostomy.

In our initial experience of kidney transplantation, we performed an extravesical uretero-cystostomy (U-C), but in 1997 we shifted to a uretero-ureterostomy (U-U) with the aim of reducing early and late urological complications. A data base was constructed to compare the incidence, donor and recipient risk factors, treatments, and outcomes of urological complications with the two techniques. From 1990 to the end of July 2004, 894 kidney transplants included 43 from living donors and 851 from cadaveric donors with 804 first and 47 second transplants. We observed 48 urinary fistulas (5.4%): 45 were successfully repaired and three were treated with a ureteral stent with two good results; and one failed at a late operation. We had 26 early stenoses (2.9%), all of which were successfully treated: 16 with surgery and 10 with a stent. Donor and recipient risk factors for fistula and early stenosis did not reach statistical significance, confirming the technical etiology of these complications. There were only six cases of late ureteral stenosis in patients operated after 1990, and in eight cases of U-C we observed vesico ureteral reflux. There were 88 urological complications, with only one kidney lost. The shift from U-C to U-U did not change the incidence of urological complications, but with U-U we observed a significant decrease in the number of postoperative urinary infections, an easier possibility to resolve ureteral stenosis with endourology and no reflux. It is now our first choice with a normal ureter.

Ureteral reimplantation for vesicoureteral reflux: comparison of minimally invasive extravesical with transvesical and conventional extravesical techniques.

OBJECTIVES: To analyze and compare the different ureteral reimplantation techniques to clarify the decision making for surgical treatment of vesicoureteral reflux. METHODS: From July 1995 to December 2000, 218 patients underwent antireflux surgery. The first 92 cases (143 ureters) were performed with the transvesical technique of Cohen (group 1), the next 37 cases (49 ureters) with the conventional extravesical technique (group 2), and the last 89 cases (113 ureters) with the new minimally invasive technique (group 3). The surgical time, length of hospital stay, postoperative side effects, frequency of pain control, and voiding cystogram findings to ensure the cessation of reflux for all patients were retrospectively analyzed. RESULTS: The success rates were similar among the different procedures. All patients in group 1 required a suprapubic cystostomy, and three had blood clot retention. Four patients in group 2 had bladder inefficiency. The surgical time ranged from 139 to 181 minutes in group 1, 58 to 94 minutes in group 2, and 40 to 61 minutes in group 3. The length of hospital stay ranged from 2.8 to 5.5 days in groups 1 and 2, and no hospital stay was needed in group 3. The frequency of analgesic administration was significantly less in group 2 compared with group 1; however, no analgesia was required in group 3. CONCLUSIONS: The results from our comparison show that the minimally invasive technique can be used as a simple and highly effective interventional procedure with less morbidity for the patient.

The management of old urethral injury in young girls: analysis of 44 cases.

BACKGROUND/PURPOSE: Traumatic urethral injury in girls is rare, and there is no consensus on its management. The authors report their 22-year experience. METHODS: Forty girls presented with urethrovaginal fistula. Twenty-six girls presented with cystostomy tube in place, whereas 17 girls presented with complete urinary incontinence. Incision and dilatation of the obliterated urethra was carried out in 7 patients. Vaginal repair of urethrovaginal fistula was performed in 4 patients. Transpubic reconstruction of the urethra using a modified Young-Dees-Leadbetter procedure with simultaneous repair of the urethrovaginal fistula was performed in 35 patients (once in 27, twice in 5, and 3 times in 3 patients). RESULTS: Follow-up in 40 girls averaged 3.5 years. Twenty-nine patients have regained normal urinary control, and 11 patients have mild stress urinary incontinence. Four patients were lost to follow-up. CONCLUSIONS: Simple dilation of the obliterated urethra can reestablish satisfactory urethral patency if the obliterated segment is short. The vaginal approach to urethrovaginal fistula may be successful in patients without concomitant urethral stricture or in those with stricture amenable to simple dilation. The transpubic approach remains the method of choice for repairing complete urethral disruption and severe urethral stricture, especially when associated with urethrovaginal fistula.

Combined cystolithotomy and transurethral resection of prostate: best management of infravesical obstruction and massive or multiple bladder stones.

OBJECTIVES: To investigate the results of combined suprapubic cystolithotomy followed by transurethral resection (TUR) of the prostate (TURP) or TUR of the bladder neck in patients with infravesical obstruction and massive or numerous bladder stones. We also reviewed the medical literature and compared the success, morbidity, and mortality rates of the treatment modality presented here and the nonsurgical modality of transurethral lithotripsy and resection of the prostate or bladder neck. METHODS: Through a 10-year period, 20 men with benign prostatic hyperplasia or bladder neck obstruction and massive or numerous bladder stones underwent cystolithotomy for stone clearance followed by TURP or TUR of the bladder neck. A second group of 20 randomly selected men who underwent TURP alone was studied retrospectively for time of surgery, number of days of postoperative indwelling catheter use, and hospital stay. RESULTS: No deaths occurred. All stones were successfully evacuated (100% stone-free rate). The operative time and number of days of postoperative indwelling catheter use and hospital stay were notoriously shorter in the present series compared with the transurethral lithotripsy and TURP modality. A single case of fever (5% complication rate) occurred in each group. When comparing the data of the present series with a group of 20 men who underwent TURP only, no differences were found in the times of postoperative indwelling catheter use and hospital stay. Cystolithotomy performed before TURP prolonged the total time of surgery an average of 18.4 minutes. CONCLUSIONS: In the era of endoscopic and minimally invasive surgery, a small suprapubic cystostomy followed by TURP is still the treatment of choice in cases of infravesical obstruction and very large or numerous bladder stones. The procedure is quick and easy to perform and bears a low morbidity rate compared with transurethral lithotripsy and TURP. A small cystotomy does not prolong the time of indwelling catheter use and hospital stay.

Congenital anterior urethral diverticulum with stone: a unique presentation.

We report the case of an 18-month-old boy with a congenital anterior urethral diverticulum containing an elliptical stone at the penoscrotal junction, with urinary retention and extravasation of urine. Initial management consisted of an open suprapubic cystostomy. Three weeks after resolution of extravasation, diverticulectomy with removal of the stone by urethroplasty was done after ruling out associated obstructing anterior urethral valves.

Urological management of cloacal anomalies.

BACKGROUND: A cloacal anomaly results from incomplete urorectal division and is frequently associated with genitourinary abnormalities. Experience of the urological reconstruction of this entity is reported. METHODS: Nine girls with cloacal malformation have been treated at the Osaka Medical Center in the past 9 years. Seven patients were detected by prenatal ultrasonography as having: megacystis (two patients); hydronephrosis (two patients); or hydrometrocolpos (three patients). Two patients underwent prenatal shunt placement between the enlarged bladder and the amniotic space. RESULTS: For neonatal urinary diversion, four patients received cystostomy. Six of seven patients with associated hydrocolpos required intermittent catheterization to decompress an enlarged vagina. Vesicoureteral reflux was detected in 12 ureters of seven patients. Antireflux surgery was indicated in four patients before definitive repair. Definitive reconstruction was performed on eight patients. The posterior sagittal approach was used in all patients. Vaginal reconstruction was done utilizing a perineal skin flap (one patient), a tubularized vaginal flap (three patients), distal rectum (three patients) and total urogenital mobilization (one patient). Postoperatively, urethrovaginal fistula was created in one patient and complete occlusion was seen in one patient. CONCLUSION: The anatomical variety of this entity determines the management options from in utero. It involves not only the creation of three perineal orifices, but also a continent, catheterizable urethra under the stabilization of renal function. Accomplishment of the definitive repair requires the combined expertise of experienced pediatric surgeons and pediatric urologists.

Electrovaporization using a rollerball electrode for flat or small papillary tumors of the bladder: basic study in dogs.

PURPOSE: We investigated electrovaporization of flat bladder tumors with a rollerball electrode 3 mm in diameter as a substitute for conventional transurethral resection with a cutting loop. MATERIALS AND METHODS: A basic study of the action of electrovaporization was performed in dogs. The bladder was exposed under general anesthesia in three mongrel dogs. The rollerball electrode was attached to the resectoscope and inserted into the bladder via a cystostomy. Then electrovaporization was performed with a low or high pressure on the electrode tip and a speed of about 1 cm/sec using a Force 40 generator. The cutting mode power was set at 100 W or 200 W. The effects of the rollerball and cutting loop electrodes were also examined in the coagulation mode (45 W) as a control. RESULTS: A deeper vaporization zone was obtained by using a power of 200 W in the cutting mode than with a power of 100 W, and a desiccation zone was found below the vaporization zone (VZ). The VZ was thicker with a high contact pressure than with a low contact pressure. This VZ was deeper than the tissue defect and heat-affected zone obtained using a rollerball electrode or cutting loop electrode in the 45 W coagulation mode. CONCLUSION: Although caution is required because the VZ can become too deep with excessive pressure, the rollerball electrode seems to be safer and more useful than the cutting loop electrode for resection of flat or small papillary bladder tumors.

Antegrade-retrograde urethrotomy for treatment of severe strictures of the urethra: experience and literature review.

In cases of urethral stricture that are nonpassable when using conventional internal urethrotomy, open urethroplasty can be avoided by performing combined antegrade-retrograde urethrotomy (ARUT). A rigid cystoscope is guided through a dilated suprapubic cystostomy channel toward the stricture in the membranous or bulbar urethra. A urethrotome is inserted in retrograde fashion, and the "cut to the light" procedure is performed. Using the ARUT method, realignment was achieved in nine patients; four of whom had strictures induced by trauma or urethritis and five of which were the result of previous transurethral management. Recurrent stricture in four of seven cases necessitated further urethrotomy. There was no recurrence in five of seven patients for at least 5 months subsequent to the last treatment. All patients were spared open surgery. The antegrade-retrograde technique was described in 1978, but to date, only 70 cases have been reported in the literature. The primary success rate is 25%. Successful retreatment following recurrence was observed in 65%. We recommend ARUT as a first-choice treatment for severe strictures of the bulbar and membranous urethra.

Salvage continent vesicostomy after enterocystoplasty in the absence of the appendix.

PURPOSE: We describe a surgical procedure for a select group of children who had previously undergone augmentation enterocystoplasty, following which intermittent catheterization became more and more difficult or impractical. A new access to the reservoir became necessary, and alternative conduits included the appendix, ureter and tubularized ileum or stomach. Each conduit had its advantages and disadvantages but all required transperitoneal dissection. We report a simple extraperitoneal surgical technique that involves use of the Mitrofanoff and Nissen principles. MATERIALS AND METHODS: A 2x6 cm. flap of the anterior wall, which is usually intestine, of the augmented bladder is raised. The base of the flap is just below the bladder dome. The flap is then tubularized over a 14F catheter and the cystostomy is closed. The bladder is plicated around the base of the tube, similar to the Nissen gastroesophageal fundoplication. The plication extends and covers the proximal 3 cm. of the tube. Intraoperative bladder distention is performed to confirm the competence of the continence mechanism. The distal part of the tube is then anastomosed to the inverted umbilical skin or to a tubularized abdominal wall skin flap. RESULTS: The aforementioned technique was used in 5 children 3 months to 6 years old. Earlier augmentation ileocystoplasty and bladder neck reconstruction had been performed in 4 children. The appendix was unavailable for a Mitrofanoff vesicostomy in all cases. This procedure was also performed on a 13-year-old boy with severe myogenic detrusor failure, due to posterior urethral valves, and a bladder capacity of 700 ml. There was no significant surgical morbidity and all children are dry between clean intermittent catheterizations 1 to 5 years postoperatively (mean 3.3). CONCLUSIONS: Use of the Mitrofanoff and Nissen principles proved to be simple and reliable, and avoided secondary intraperitoneal exploration and use of bowel in these select cases.

Urinary control after the definitive reconstruction of cloacal anomaly.

PURPOSE: Urinary control after definitive repair of a cloacal anomaly is difficult to achieve. The present report aims to describe the clinical course of urinary control, and the need for the management of bladder dysfunction after reconstruction. METHODS: The present consecutive series consisted of 11 girls who underwent definitive repair of cloacal anomalies over a period of 11 years. Eight patients were associated with hydrocolpos. Radiological examination included a plain X-ray radiograph of the lumbosacral spine and a voiding cystourethrography with or without a urodynamic study. RESULTS: Reconstruction of the cloaca was performed on patients aged between 1 and 3 years using a posterior sagittal approach. Vaginal reconstruction was carried out 13 times in 11 patients using tubularized vaginal flap, distal rectal segment, perineal skin flap, or total urogenital sinus mobilization. Cystostomy or vesicostomy was carried out in four newborns/infants. Another seven patients could void spontaneously but incompletely with residual urine. Occult spinal dysraphism was found in five patients and hemisacrum in two patients. After definitive reconstruction, most patients acquired an adequate to normal bladder volume for 1-year-olds. Normal detrusor-sphincter function was seen in three patients. Detrusor areflexia was seen in two patients who underwent in utero vesico-amniotic shunt. Detrusor underactivity was observed in six patients. Bladder compliance was good in all patients except for one. No patients in the present series showed persistent urinary incontinence from the bladder neck or urethral dysfunction. CONCLUSION: It is postulated that wetting after definitive repair may be the result of overflow incontinence and poor bladder contractility rather than sphincter injury. The main clinical characteristic of bladder dysfunction was a failure to empty. We could not define the exact etiology, but iatrogenic injury from extensive dissection can lead to the higher risks of peripheral nerve damage. Accomplishment of definitive repair involves not only anatomical reconstruction, but also postoperative urinary control, including the initiation of clean intermittent catheterizations under repeated urodynamic evaluations.

Treatment of vesicoureteric reflux in the neurogenic bladder.

A retrospective co-operative study was conducted among 6 Italian paediatric surgical departments to assess the results of different forms of treatment of vesicoureteric reflux in patients with neurogenic bladder. Between January 1980 and December 1989 we studied 641 neurogenic bladders in children, mainly due to spina bifida; reflux was detected in 199 patients with 263 refluxing ureters. Details of treatment were available for only 170 patients and they were divided into 2 main groups: conservative medical treatment (n = 127) and primary surgical treatment (n = 43). Medical treatment consisted mainly of clean intermittent catheterisation and the administration of appropriate drugs. In the surgical group 36 reimplantations, 6 cystostomies and 1 STING were performed. Fifteen patients underwent surgery as a secondary procedure. The results showed that approximately 50% of patients with reflux were cured by clean intermittent catheterisation and drug therapy. Ureteric reimplantation can be safely performed in patients with neurogenic bladder provided that a normally compliant, non-hyper-reflexic bladder can be achieved by means of drugs or by bladder augmentation with bowel.
