[Continent urinary diversion with the Florida pouch]

Continent urinary diversion (Florida Pouch) has been performed on 151 patients. The surgical technique utilizes a detubularized extended right colon segment, a doubly-plicated segment of ileum and a non-tunneled uretero-intestinal anastomosis. Mortality rate was 1.3%. Early and late complication rates have been minimal. 2.8% were incontinent. No radiographic renal damage has been noted and electrolyte abnormalities have not been a problem. The procedure is highly recommended to those surgeons performing continent urinary diversions.

Conversion from external appliance wearing or internal urinary diversion to a continent urinary reservoir (Florida pouch I and II): surgical technique, indications and complications

A total of 20 patients with diversion requiring an external appliance or internal urinary diversion underwent conversion to a continent urinary reservoir (Florida pouch I or II). All patients subsequently reported an improvement in the quality of life and expressed satisfaction with the new urinary diversion procedure. Of the patients 15 (75%) previously had an ileal conduit, while 1 (5%) had undergone ureterosigmoidostomy, 1 (5%) had cutaneous ureterostomy, 1 (5%) had a suprapubic tube, 1 (5%) had a sigmoid conduit and 1 (5%) had a cecal conduit. After the original diversion 3 patients (15%) had recurrent urinary infections, 3 had complications related to the stoma and external appliance (stenosis and skin dermatitis) and 5 (25%) had ureteral obstruction in 7 ureters. A total of 17 patients with conduits (85%) underwent conversion via different surgical technical aspects depending on the status of the intestinal segment from the conduit and the function of the ureteral reimplantation: in 14 the conduit was discarded or was used only to patch the newly created Florida I colonic pouch, while in 6 the conduit was preserved and 9 ureterointestinal reimplantations were left undisturbed (Florida pouch II). Among 7 ureters preoperatively obstructed (original diversion), reimplanting them into the pouch failed to prevent further renal damage in 5 (71%). Three renal units required nephrectomy, 2 kidneys deteriorated and 2 recovered renal function after percutaneous balloon dilation and stenting. Among 31 preoperatively nonobstructed renoureteral units (original diversion), 22 were reimplanted into the colonic reservoir. One of these units (4.2%) became obstructed postoperatively and 3 (13.5%) presently have reflux. The 10 reimplantations left undisturbed in the detubularized conduit drain satisfactorily without postoperative obstruction and in 6 reflux has not been demonstrated. Renal function (serum creatinine) is preserved in all patients but 15 (75%) have hyperchloremia of mild degree. Two patients (10%) have acidosis and 1 (5%) of these had low red blood cell folic acid. Conversion of an external or internal diversion to a continent colonic urinary reservoir (Florida pouch I or II) can be successful and improve the quality of life of the patient. The functioning renal units that were preoperatively obstructed were associated with a high failure rate (71%) after reimplantation. Metabolic alterations will require long-term followup, and are particularly worrisome in children and young adults.

Results, complications and surgical indications of the Florida pouch

One hundred and seven patients underwent continent urinary diversion using an extended, detubularized right colonic segment as the urinary reservoir and the distal part of the ileum as a continent catheterized efferent system. This reservoir allows the accommodation of a large volume of urine; urodynamics in 28 patients demonstrated a maximum reservoir capacity varying between 550 and 1,200 milliliters (an average of 747 milliliters). The reservoir maximal volume and pressure remains unchanged in six patients studied urodynamically three to four years postoperatively. Maximal reservoir pressures ranged between 10 and 58 centimeters of H2O (an average of 35 centimeters). Of 201 ureterocolonic reimplantations, four ureters were initially reimplanted using a modified Le Duc procedure, 26 ureters were subsequently managed using the Goodwin transcolonic approach and 165 reimplantations were done with a direct (nontunneled) mucosa to mucosal anastomosis. The over-all success rates with each of the three techniques (absence of reflux and obstruction) have been 75.0, 84.7 and 87.4 per cent, respectively. However, the incidence of obstruction was 13.3 per cent for the tunneled and 4.2 per cent for the non-tunneled reimplantations. Six megaureters underwent imbrication and direct reimplantation, and three of these became obstructed. One patient died of pulmonary embolism. Medical and surgical complications markedly predominated in the group who underwent simultaneous cystectomies, and in this group, the over-all complication rate was comparable with that for previously reported series with ileal conduits. The double row plication of the distal part of the ileum and ileocecal valve allows easy catheterization every four to six hours and 105 patients (97.2 per cent) remained continent between catheterizations. The stoma is covered using a small gauze, cap or sterile adhesive strip. This protects clothing from mucus production by the stoma and an occasional episode of urinary dribbling. Seven patients required reoperation for correction of incontinence or other complications. Our satisfactory experience with these patients makes this technique an excellent approach to achieving continent urinary diversion.

Intravesical bacillus Calmette-Guerin for patients with high-risk superficial bladder cancer

Intravesical bacillus Calmette-Guérin (BCG) was employed in the treatment of 55 patients with aggressive superficial transitional cell carcinoma of the bladder (cTa, cT1, cTis). All of the patients had a previous history of recurrent superficial disease, and 41 (75%) were treatment failures following other intravesical therapy. Thirty-six (66%) patients responded to treatment, and 19 (34%) were treatment failures. Twenty-seven (66%) of 41 patients with cTa-cT1 tumors and 9 (64%) of 14 patients with cTis responded, with a mean follow-up period of 30.5 months. Disease progression was noted in 8 (15%) of the patients and muscle invasive disease in 6. Patients with a history of three or more previous events of tumor recurrence, positive urinary cytology, and multicentric disease, all fared worse than patients without these characteristics (p less than 0.05). BCG is an effective agent in controlling superficial transitional cell carcinoma of the bladder, even in a high-risk group of patients who failed previous intravesical therapy. BCG should be employed in this group of patients prior to radical surgery.

A continent colonic urinary reservoir: the Florida pouch

A total of 92 patients underwent continent urinary diversion with an extended, detubularized right colonic segment as the urinary reservoir and the distal ileum as a continent catheterizable efferent system. In this series 65 patients were followed for 6 to 46 months (average 17 months). Our reservoir allows the accommodation of a large volume of urine; urodynamic studies in 28 patients demonstrated a maximum reservoir capacity varying between 550 and 1,200 cc (average 747 cc). Maximal reservoir pressures ranged from 10 to 58 cm. water (average 35 cm. water). Of the 127 ureterocolonic reimplantations 4 ureters were initially reimplanted with a modified Le Duc procedure, 26 ureters were managed subsequently with the Goodwin transcolonic approach and 91 reimplantations were done with a direct (nontunneled) mucosa-to-mucosa anastomosis. The overall success rates with each of the 3 techniques (absence of reflux and obstruction) were 75, 88.6 and 90.1%, respectively. Six megaureters underwent imbrication and direct reimplantation, and 3 of these (50%) became obstructed. Two converted ileal conduits were opened at the antimesenteric edge and were patched to the reservoir while the ureteroileal anastomosis was left undisturbed. One patient (1.5%) died of pulmonary embolism. Medical and surgical complications occurred only in the group who underwent simultaneous cystectomy and the over-all rate of complication was comparable to previous series with ileal conduits. The double row plication of the distal ileum and ileocecal valve allows for easy catheterization every 4 to 6 hours and 63 patients (97%) remain continent between catheterization. Four patients (6%) required reoperation for correction of incontinence or other complications. Our satisfactory experience with these patients makes this technique an excellent approach to achieving continent urinary diversion.

Combined cystourethropexy for the treatment of type 3 and complicated female urinary incontinence

We treated 37 women with type 3 stress urinary incontinence or with an associated complicating factor, such as morbid obesity, a large or proximal diverticulum or a urethrovaginal fistula, via combined transvaginal cystourethropexy. All women with type 3 stress incontinence had failed a previous anti-incontinence operation. Patients in both groups underwent suprapubic needle suspension and an additional bladder neck support procedure. Among 33 patients who underwent preoperative urodynamic studies 30 had stable bladders (90%), while 3 had low pressure detrusor instability (10%). The success rate in achieving continence, including cured and improved patients, was 94.6% with a followup of 3 to 72 months. Four patients (10%) required temporary intermittent catheterization for 3 to 4 weeks but none presented with long-term voiding dysfunction. The added bladder neck support improved our results in these complicated female incontinence cases compared to the standard suprapubic needle suspension procedures alone. The combined procedure currently is our method of choice for treatment of type 3 and other complicated cases of female urinary incontinence.

Transabdominal radical nephrectomy in ninety-one consecutive patients with Wilms' tumor

Ninety-one children that were subjected to transabdominal radical nephrectomy are reviewed. The patients' ages ranged from 20 days to 10 years. Forty cases had a right side tumor and 44 a left side tumor; bilateral tumor incidence was 7.70% (7 cases). The tumor weight incidence was 75% for greater than or equal to 500 g and 37.5% for greater than or equal to 1,000 g. Incidence of local extension of the disease was 21.98%. Intraoperative complications were 12 ruptures of the kidney capsule, 1 laceration of the cecum, 1 opening of the pleura, 1 section of the superior mesenteric artery, and 1 section of the right common iliac artery. The mortality rate in unilateral surgery, because of intraoperative massive hemorrhage, was 3/83 (3.61%). One patient with bilateral tumor died because of acute renal insufficiency and sepsis. One patient with caval thrombus which extended up to the right atrium died because of intraoperative massive pulmonary embolism.

Bilateral ilioinguinal lymph node dissection in the management of cancer of the penis

Twenty-nine patients with squamous cell carcinoma of the penis underwent bilateral ilioinguinal groin dissection 6 weeks after removal of the primary penile lesion. Eighty percent of the patients were alive and without evidence of disease at 5 years when the dissected lymph nodes were negative. When positive nodes were found, 62.5% of the patients were alive and without evidence of disease at 5 years: two of these patients had one iliac deep node positive each. The mortality rate at 5 years because of progression of disease was 6.6% when the dissected lymph nodes were negative, as compared to 37.5% when the dissected lymph nodes were positive.

Transrectal ultrasound of the prostate

One hundred and twenty-one transrectal ultrasound examinations of the prostate were performed between August and October of 1987. Indications included screening in 41 patients, evaluation of bladder outlet obstruction in 63 patients, evaluation of palpable nodules in 6 patients, and evaluation after transurethral resection of the prostate in 11 patients. A total of five patients were discovered to have prostate cancer after biopsy of a hypoechoic lesion in a normal feeling prostate by digital rectal examination. One patient was from the screening group, two patients with bladder outlet obstruction and two patients from the postransurethral resection group. All six patients with palpable nodules were diagnosed as having a cancer: Stage B2 on the rectal examination and two of the six patients were upstaged to Stage C by ultrasound criteria. In our hands transrectal ultrasound of the prostate is a valuable adjunct in the urological armamentarium with clear application in the diagnosis and staging of prostate cancer.

Primary malignant melanoma of the male urethra

Primary malignant melanoma of the male urethra is a rare disease, with only 24 cases previously reported in the literature, including 1 black patient. We describe 2 additional patients with primary malignant melanoma of the urethra, one of whom was a black man. The literature is reviewed briefly and treatment recommendations are discussed.

Female urinary incontinence: preoperative selection, surgical complications and results

A total of 98 women with stress urinary incontinence underwent surgical repair via 3 different techniques: 38 patients underwent a Burch colposuspension (group 1), 25 underwent a Stamey procedure (group 2) and 35 had a modified Pereyra operation (group 3). The main indication for an operation was clinically unacceptable incontinence, and urodynamic studies were done on all patients with associated stress and urge incontinence or who underwent reoperation. Subtracted bladder pressure recording was an important preoperative screening tool, since patients with high pressure instability did worse surgically than those with a stable bladder or low pressure instability. In patients with detrusor stability similar results were achieved for initial surgery and reoperations. Among the patients with a stable bladder with and without a previous anti-incontinence operation the over-all results were better in groups 1 and 3 than in group 2. Complications were of lesser magnitude in groups 2 and 3 than in group 1.
