Genital Fournier's gangrene: experience with 38 patients.

OBJECTIVES: Fournier's gangrene (FG) is an extensive fulminant infection of the genitals, perineum, or the abdominal wall. We report our experience with the management of this difficult infectious disease. METHODS: Thirty-eight patients were admitted with the diagnosis of FG between May 1993 and May 1995. All patients were treated with broad-spectrum triple antimicrobial therapy, broad debridement, exhaustive cleaning, and application of unprocessed honey dressings. Patients then underwent split-thickness skin grafts or delayed closure as needed. RESULTS: Patient ages ranged between 33 and 86 years (mean, 54) with a mean hospital stay of 17 days (range, 1 to 45). Sixty-six percent of the patients were diabetic, 16% had previous orchiepididymitis, and 5% had scrotal and urethral trauma. All the patients underwent surgical debridement and application of unprocessed honey to the wound. Cystostomy was performed in 60% of the patients and 21% underwent orchiectomy of the affected side. Free skin grafts were applied to 6 patients (16%) and the remaining wounds, once clean, were approximated. One patient died as a result of severe metabolic acidosis and sepsis. CONCLUSIONS: The management of this infectious entity should be aggressive. Patients with FG need extensive debridement and cystostomy or colostomy when necessary. Broad-spectrum triple antimicrobial regimen and aggressive debridement are mandatory. Topical application of unprocessed honey is beneficial to the healing process. A minority of patients require split-thickness skin grafts on denuded areas.

Evaluation of different methods of bladder drainage used in the early care of spinal cord injury patients.

In a series of 115 spinal cord injury patients four different methods of bladder drainage were used mainly during spinal shock. That is a) suprapubic fine bore cystostomy, b), indwelling Foley catheter, c) intermittent catheterisation; and d) both last methods consecutively. The methods of bladder drainage used did not influence the number of patients becoming catheterfree but determined significantly the length of period before patients became catheterfree. Patients on intermittent catheterisation had the shortest time from injury to established micturition. Patients on intermittent catheterisation and on cystostomy had few complications but in those patients treated with an indwelling Foley catheter the complication rate was high.

Endoscopic treatment of quadrigeminal cistern arachnoid cysts.

Five patients with arachnoid cysts of the quadrigeminal cistern treated by endoscopic fenestration are reported and another eleven well-documented cases from the literature are reviewed. Among the five personal cases four were children and one was adult; the cyst fenestration was performed from the lateral ventricle in three cases and from the third ventricle in two. In four patients the endoscopic treatment resulted in clinical remission, whereas a two-month-old baby later required a shunt. The lateral ventricle-cystostomy and the third ventricle-cystostomy (according to the cyst extent) are the best endoscopic procedures, whereas the cyst fenestration through a suboccipital supracerebellar approach is no longer used. The rate of cured or improved patients after endoscopic surgery (14/16 or 87.5%) was rather similar to that of a group of twenty patients treated by traditional surgery (craniotomy and cyst excision and/or shunt) (85%). These data confirm that endoscopic fenestration of quadrigeminal cistern cysts must be performed as the first procedure because it is less invasive and avoids shunt dependency.

[Safety and effectiveness of endosurgical management of benign adnexal tumors in the premenopausal period: a prospective study].

Between January 1985 and December 1989, a prospective laparoscopic study was performed in premenopausal women with pelvic cysts growing or persisting for at least three months or evoking acute abdominal complaints. The aim of this prospective study was the investigation of the functional/nonfunctional rate, the relapse and the malignancy rate. 372 women underwent a diagnostic-operative laparoscopy in the absence of irregular solid and cystic parts detectable by preoperative vaginal ultrasonography. The treatment consisted of non-randomised endosurgical ovarian cystostomy, cystectomy or ovarectomy. Histopathological assessment showed functional ovarian cysts in 268 women and non-functional benign ovarian tumours in 104. 2 cases were subsequently found to be malignant. After a mean follow-up-time of at least one year, we found an overall recurrence rate of 4.6% after cystostomy, 2% after cystectomy and 0% after ovarectomy in the group of functional ovarian cysts and a total of 1% after endosurgical therapy of the non-functional ovarian tumours. The diagnostic operative laparoscopy proved to be a safe and efficient treatment of pelvic cysts in women of reproductive age, provided a sufficient preoperative vaginal ultrasound examination had been performed.

Urethral injury in the multiple-injured patient.

A total of 74 patients with urethral injury due to external trauma consisted of 48 posterior urethral injuries (25 complete rupture, 23 partial rupture) and 26 anterior urethral injuries (two complete rupture, 16 partial rupture, and eight contusion). The diagnosis was made by retrograde urethrography. All 48 patients with posterior urethral injury had associated injuries, including a fractured pelvis in 46, and a mortality rate of 33%. Only seven of the 26 patients with anterior urethral injury had associated injuries and a mortality rate of 14%. The management of posterior urethral injury is changing from primary realignment of the ruptured urethra to suprapubic cystostomy alone and followed later by urethral surgery for the resulting stricture. The impotence rate is significantly lower with management with suprapubic cystostomy alone. However, the type of pelvic fracture, the urethral injury itself disrupting neurovascular structures, and the surgical dissection (initial primary realignment or delayed urethroplasty) must be investigated before it can be determined whether the impotence associated with pelvic trauma is caused by the injury itself or by the surgical dissection undertaken to reconstruct the urethra.

Straddle injuries to the bulbar urethra: management and outcomes in 78 patients.

PURPOSE: We describe our experience with blunt straddle injuries to the anterior urethra and identify factors that may affect patient outcome. MATERIALS AND METHODS: We reviewed the San Francisco General Hospital Urologic Trauma data base to identify men with blunt straddle injury. We analyzed presentation and initial management, location and length of urethral stricture, surgical options, and long-term outcome after reconstruction. RESULTS: Of 78 patients, 40% presented to the emergency department acutely and 60% presented 6 months to 10 years after injury complaining of obstructive symptoms, of whom 30% reported at least 1 episode of urinary retention. Initial acute management was suprapubic cystostomy in 81% of cases and primary realignment in 19%. Urethral strictures were predominantly located in the proximal bulb. Mean stricture length was significantly longer in men with delayed presentation (2.7 vs 1.8 cm, p <0.05). No relationship was found between stricture length and the mechanism of injury or initial management technique. However, patients who had undergone primary realignment required complex flap or graft urethroplasty at a greater rate compared with men who had undergone suprapubic diversion (p = 0.054). Transperineal urethroplasty was required in 92% of patients with the majority undergoing end-to-end anastomosis. The success rate was 95% at a mean followup of 25 months (range 10 to 180). Recurrent stricture occurred in 4 men with prior urethral manipulation and it was managed successfully by direct vision internal urethrotomy alone. CONCLUSIONS: After blunt straddle injury to the perineum the primary morbidity is anterior urethral stricture, for which suprapubic cystostomy is appropriate initial management. The majority of patients require surgery but with careful preoperative planning and adequate resection of fibrotic tissue the long-term success rate can approach 95%. If it arises, recurrent stricture responds well to direct vision internal urethrotomy alone.

Long-term results of treatment of urethral injuries in males caused by external trauma.

Of 134 males with traumatic rupture of the urethra seen between 1967 and 1989, 10 have been lost to follow-up and 124 have been followed up for 1 to 22 years (mean 8); 100 patients had a pelvic fracture (3 with associated rectal injury) and 24 had perineal injuries. Prior to referral 31 patients (25%) had undergone treatment in addition to suprapubic cystostomy. Wherever possible, strictures were managed by optical urethrotomy (33) or intermittent dilatation (4). In 2 patients only a suprapubic cystostomy was possible. Skin inlay urethroplasty in 1 or 2 stages was performed in 75 cases, an end-to-end anastomosis with or without resection of the symphysis pubis in 7 and a scrotal tube pull-through in 3. The immediate and long-term results depended on the severity of the original injury. With minimal displacement the management was simple and the long-term prognosis good, a single urethrotomy being sufficient in 22 patients. Where there was considerable displacement the initial management was more difficult and there was a high incidence of long-term complications: of 73 patients treated by urethroplasty or end-to-end anastomosis, significant post-operative infection occurred in 11 (15%) and restenosis in 15 (20%), of whom 7 required a revision urethroplasty. Data in respect of potency were recorded in 80 patients: 28 of these were impotent, 20 of the 28 having sustained an injury with considerable displacement.

Transurethral resection in the management of urethral and prostatic neoplasia in 6 dogs.

OBJECTIVE: To assess cystoscopic transurethral resection (TUR) for the palliative management of dogs with neoplastic infiltration of the urethra. STUDY DESIGN: Prospective clinical trial. ANIMALS: Six client-owned dogs. METHODS: Cystoscopic examination and electrosurgical TUR were performed in dogs with urination difficulties caused by prostatic or urethral neoplasia. TUR was performed in a retrograde manner in female dogs and antegrade in male dogs via exploratory celiotomy and ventral cystotomy. Cystoscopic examination was used to determine the extent of neoplastic involvement of the urethra. TUR involved piecemeal removal of neoplastic tissue from the urethral lumen using an electrocautery cutting loop. Hemorrhage was controlled with a cystoscopic cauterized roller-ball. In 2 male dogs, intraoperative radiation therapy (IORT) was used to treat both prostatic neoplasia and the sublumbar lymph node bed. Surgical technique, complications, adjuvant treatment, and outcome were recorded. RESULTS: TUR was performed in 3 male dogs with prostatic carcinoma and 2 female dogs with urethral transitional cell carcinoma (TCC). In 1 female dog, TUR was attempted but not successful because of cystoscope diameter. Iatrogenic urethral perforation occurred during TUR in 3 dogs. In 2 dogs, prolonged exposure to lavage fluid resulted in clinical and biochemical abnormalities consistent with TUR syndrome. Dysuria resolved in 5 dogs within 10 days of TUR. Treatment-related complications included urinary tract infection and tumor seeding. Local tumor progression and metastasis occurred in all dogs. CONCLUSIONS: TUR (in combination with chemotherapy+/-IORT) resulted in rapid palliation of urination difficulties in male dogs with prostatic carcinoma. In female dogs with urethral TCC, however, electrosurgical TUR cannot be recommended because of a high intra- and postoperative complication rate with no improvement in postoperative management compared with historical reports of tube cystostomy. CLINICAL RELEVANCE: TUR is a novel alternative for the palliation of male dogs with prostatic carcinoma. In female dogs with urethral TCC, electrosurgical TUR does not provide any advantages compared with tube cystostomy.

Longitudinal urethral sling with prepubic and retropubic fixation for male urinary incontinence.

OBJECTIVE: Description and early results of a new urethral sling technique for treatment of postprostatectomy urinary incontinence, which combines efficacy, low cost and technical simplicity. MATERIALS AND METHODS: From May 2003 to April 2004, 30 patients with moderate or total urinary incontinence, following radical prostatectomy or endoscopic resection of the prostate, underwent the new technique. The technique is based on the placement of a longitudinal-shaped sling in the bulbar urethra, measuring 4 cm in length by 1.8 cm in width, made of Dacron or polypropylene mesh, fixed by 4 sutures on each side, with 2 sutures passed with Stamey-Pereira needle by retropubic approach and 2 by prepubic approach, which are then tied over the pubis. Pressure control was determined by interrupting the loss of infused water through a suprapubic cystostomy 60 cm from the pubis level. RESULTS: Pre-operative assessment excluded vesical instability, urethral stenosis and urinary infection. Suprapubic cystostomy was removed when the patient was able to satisfactorily void with urinary residue lower than 100 mL, which occurred in 29 of the 30 cases. In 2 cases, there was infection of the prosthesis, requiring its removal. In 3 cases, there was the need to adjust the sling (increasing the tension), due to failure of the urinary continence. Overall, 20 of 30 (66.7%) operated patients became totally continent, and did not require any kind of pads. Four of 30 (13.3%) patients achieved partial improvement, requiring 1 to 2 pads daily and 6 of 30 (20%) patients had minimal or no improvement. There was no case of urethral erosion. CONCLUSION: This new sling technique has shown highly encouraging preliminary results. Its major advantage over other surgical techniques for treatment of moderate or severe stress urinary incontinence is the simplicity for its execution and low cost. A long-term assessment, addressing maintenance of continence, detrusor function and preservation of the upper urinary tract, is still needed.

[Neurogenic bladder dysfunction due to spina bifida and sacral dysgenesis manifested itself in middle age. Report of a case].

Congenital neurogenic bladder dysfunction with spina bifida and sacral dysgenesis manifested itself at middle age is reported. A 48-year-old male who had urinary retention and suprapubic cystostomy one year and a half before in another hospital was seen, asking for removal of the cystostomy. He had never had any neurologic or bladder dysfunction in his childhood and adulthood. X-ray examination revealed a bifid spine and sacral dysgenesis, bilateral hydronephrosis, bilateral VUR and urethral stricture. Uroflowmetry showed a severe dysuric pattern (voided volume 5 ml, residual urine 230 ml) and the cystometrogram revealed a hyperactive bladder. Optical urethrotomy for stricture yielded some improvement i.e. recovery of voluntary voiding with large amount of residual urine. TUR of the bladder neck resulted in almost complete voiding. Cohen's antireflux operation yielded favorable improvement of hydronephrosis. The bladder and renal function remained favorable in the follow-up period of about two years. The clinical course of this patient suggested that his bladder dysfunction was due to late manifestation of congenital neurogenic bladder.

[Ureteral function at the ureterovesical junction. Action potentials of the canine intramural ureter during bladder filling or bladder contraction].

The relationship between bladder movements and the intramural ureter was studied in the dog by recording electromyograms of the intramural and extravesical ureters recorded during bladder filling and contraction. Bladder filling was achieved by instilling physiological saline at a rate of 10 ml/min to a volume of 5 ml/kg, while bladder contraction was induced by electrical stimulation. For electromyography, an electrode was inserted transperitoneal into both the extravesical ureter and the intramural ureter after it had been separated from the extravesical ureter. A cystostomy for the instillation of water and another cystostomy for the measurement of intravesical pressure were also made in the bladder. During bladder filling at an intravesical pressure of about 10 cmH2O, the frequency of the action potentials in the intramural ureter showed no significant difference to those in the extravesical ureter. In addition, during bladder contraction at a greatly increased intravesical pressure of about 5 times the precontraction level, the frequency of the action potentials in the intramural ureter was not significant by different from those in the extravesical ureter, and also from its own precontraction value. The above findings suggest that action potentials in the intramural ureter are not affected by bladder movements such as filling or contraction, and that the ureter continues to actively transport urine to the bladder during such movements.

[Intraoperative blood recovery in transurethral resection of prostate (TURP)].

Blood collected from irrigating fluid in TURP was studied if it was appropriate blood as autologous transfusion or not. TURP was performed aided by continuous irrigation through suprapubic cystostomy. The cystostomy tube was connected to the Shiley STAT or Haemonetics Cell Saver in 15 patients. The average weight of resected adenoma was 36 g per patient. The product of washed blood gave an average yield of 440 ml per patient with an average RBC count of 469 x 10(3)/mm3, hemoglobin of 14.6 g/dl, hematocrit of 44.8%, platelets of 15400/mm3. The half-life of collected red blood cells tagged with 55Cr was 22 days. The urine in 10 patients (67%) were contaminated with bacteria before TURP, and 3 of collected blood were contaminated with bacteria (20%). As for carcinoma cells, cultured urinary bladder carcinoma cells (T24) and renal carcinoma cells (ACHN) were completely eliminated after filtration through leukocyte removal filter Sepacell or Pall RC. As results, the intraoperatively collected blood from irrigating fluid in TURP was useful and safe as autologous blood transfusion.

[Abscess of corpus cavernosum: a case report].

A 72-year-old man was admitted to our hospital complaining of a penile mass. The local biopsy indicated an abscess formation in the corpus cavernosum. In spite of antibiotic treatment, the abscess cavity ruptured to the dorsal skin and the urethra. After cystostomy formation, dorso-caverno-urethral fistula was closed by conservative therapies. Although the patient was followed up with antibiotics on an outpatient basis, necrotic changes in the right foot were noticed and he was diagnosed with arteriosclerosis obliterance in the right lower leg. Therefore, he was referred to an orthopedic clinic for amputation of his right lower leg with cystostomy catheter. This is the 7th case reported in Japan.

Posttraumatic complete and partial loss of urethra with pelvic fracture in girls: an appraisal of management.

PURPOSE: Urethral injury in girls accompanying fracture of the pelvis is rare. We present our experience with 5 such complex cases and review the literature to define the types of problem and determine appropriate management. MATERIALS AND METHODS: We report on 5 girls with posttraumatic urethral injuries and pelvic fracture resulting in stricture as well as management based on the site and length of urethral stricture. Associated injuries and results are discussed. RESULTS: Of the 5 girls who presented with stricture 4 had undergone suprapubic cystostomy as initial treatment, whereas in 1 primary repair had failed. Urethral reconstruction using a bladder flap tube and distal urethrotomy into the vagina were performed in 3 and 1 cases, respectively. These 4 girls were continent although 1 required clean intermittent catheterization for a short period. The 3 patients with complete urethral loss had a more severe degree of pelvic fracture, including 1 treated with core through internal urethrotomy. CONCLUSIONS: Posttraumatic urethral injury accompanying pelvic fracture in young girls results in challenging management situations. More severely displaced pelvic fracture is associated with greater urethral loss and requires more complex repair. Cases of partial urethral injury or urethral transection without much displacement are better managed by primary repair of the transected urethra, which decreases morbidity. Primary repair may not be feasible in patients with extensive injury, who should be treated with secondary appropriate reconstruction after preliminary suprapubic cystostomy. Complete urethral loss may be managed by bladder flap tube neourethra creations with effective continence and excellent outcomes. Short segment distal urethral strictures may be treated with meatotomy or core through internal urethrotomy.

Bladder dysfunction after acute urinary retention in rats.

PURPOSE: We investigated bladder function in acute urinary retention and subsequent catheterization in rat bladders. MATERIALS AND METHODS: The penile urethra in rats was clamped with a small clip and cystostomy was performed to infuse 3 ml. of saline for inducing acute urinary retention. At 30 minutes after the induction of urinary retention the cystostomy was opened to empty the bladder. In functional studies contractile responses to carbachol were measured in group 1-before, group 2-at 3 ml. of urinary retention, group 3-at 3 ml. of urinary retention exposed for 30 minutes and group 4-30 minutes after catheterization. Moreover, in vivo real-time monitoring of blood flow and vesical pressure were measured in the bladders with a laser Doppler flowmeter and cystometrography, respectively. Malonaldehyde and 4-hydroxyalkenals were measured by colorimetric assay in these groups. RESULTS: In functional studies the mean maximum contractile response value plus or minus standard deviation of carbachol-to-bladder in groups 1 to 4 was 11.8 +/- 1.3, 11.9 +/- 1.7, 9.8 +/- 0.8 and 6.9 +/- 0.7 gm./mm.2, respectively. In real-time monitoring of blood flow and vesical pressure acute urinary retention significantly decreased blood flow and increased vesical pressure, and subsequent catheterization increased blood flow and decreased vesical pressure in the bladders. The concentrations of malonaldehyde and 4-hydroxyalkenals in the bladders in group 4 were significantly higher than in the other groups. CONCLUSIONS: Our data indicate that bladder dysfunction after catheterization is partially caused by free radicals, which have an important role in bladder dysfunction during acute urinary retention.

Squamous cell carcinoma of the eviscerated bladder: a case report.

This is a report of a squamous cell carcinoma of the eviscerated bladder in a 52-year-old-Thai man. He had a history of pelvic fracture and failed urethroplasty. The bladder mucosa was eviscerated out from cystostomy tract after the spontaneous dislodging of the cystostomy tube. Squamous cell carcinoma developed at the eviscerated bladder 5 years later. The treatment consisted of radical cystectomy and ileal conduit with combination of radiotherapy. The patient died 7 months after operation due to liver metastasis. Correction or excision of the eviscerated bladder can prevent this kind of cancer.

[Endoscopic surgery of stress urinary incontinence, using the Stamey needle].

OBJECTIVE: To describe the utility of endoscopic management of stress urinary incontinence with Stamey's needle. METHODS: 50 multiparas (2-8 deliveries; mean 4) aged 26-72 years (mean 42) consulted for stress urinary incontinence. All patients were evaluated by the Valsalva maneuver, cough and perineal ultrasound and were classified as mild (8 cases), moderate (26 cases) and severe (16 cases). Thirty-eight patients had cystocele. Bladder neck suspension with Stamey's needle was performed in all patients. A cystostomy and not a urethrovesical catheter, was left indwelling in all patients. RESULTS: Multiparity and management at childbirth were the most common factors associated with stress urinary incontinence. Perineal ultrasound was found to be useful in the evaluation of the incontinent patient and the surgical procedure. The endoscopic procedure permits physiologic correction of stress urinary incontinence and cystocele. CONCLUSIONS: Endoscopic surgery with Stamey's needle reduces the operating time, length of hospital stay, recovery time and surgery-related pain. Patient management is facilitated by cystostomy.

[A case of vesico-urethral foreign body with urinary fistula].

We report a rare case of vesico-urethral foreign body with urinary fistula. On March 12, 2002, a 53-year-old single men inserted a 3 m vinyl tube 6 mm in diameter into his urethra by himself for the purpose of masturbation, but he could not remove the tube. He cut his urethra by himself and tried to remove the tube. The next day he was admitted to our hospital, with complaints of urinary fistula and fever. Open surgical removal of foreign body, cystostomy and repair of bulbous portion of the urethra were performed. At 24 days postoperatively the cystostomy and urethral catheter were removed and urination became smooth.
