Laparoscopic nephrectomy: an established routine procedure.

Between August 1992 and April 1993, 60 patients underwent laparoscopic nephrectomy in our institution for benign disease (35 hydronephrosis, 20 chronic pyelonephritis, 4 end-stage kidney, 1 renal hypoplasia). Conversion to open surgery was needed in six cases to overcome intraoperative bleeding or perirenal adhesions. The mean operative time was 3.5 +/- 1.3 hours, and the mean hospital stay was 3.2 +/- 2.1 days. No deaths occurred, but significant complications were encountered in four cases in the form of pulmonary embolism, a large hematoma, postoperative bleeding, and colonic perforation. Laparoscopic nephrectomy is a safe and effective alternative to open nephrectomy for benign renal conditions.

Postrenal transplant urethral Kock pouch.

We report on a man with schistosomal bladder who developed stage T3N0M0, grade II transitional cell carcinoma of the bladder 9 years following successful renal transplantation. Radical cystoprostatectomy was performed and urethral Kock pouch was implanted in the same setting. The patient was continent and the graft function was maintained without reflux or obstruction at a follow-up period of 2 years. No complications due to poor intestinal healing or intraabdominal sepsis were observed despite immunosuppression and electrolyte disorders were minor.

Interposition of ileum in the ureter.

An ileal loop was interposed to replace a long defect of the upper ureter with preservation of the lower ureteral continuity in three patients. Urinary drainage was satisfactory and at follow-up 2-4 years postoperatively renal function was improved.

Salvage of difficult transplant urinary fistulae by ileal substitution of the ureter.

We report our experience with 4 cases of ileal substitution of the ureter after live-donor kidney transplantation and review the literature. The indications were recurrent ureteric fistula and obstruction in 3 cases and extensive necrosis of the ureter and renal pelvis in one case. Nephrostomy tube drainage was a useful adjunct to diagnosis and treatment of the 4 cases. No mortalities or graft losses were encountered and satisfactory graft function was maintained 2-14 years after ileal substitution of the ureter. Moreover, no electrolyte or acid-base disturbances were observed. One patient developed recurrent vesical stones 2 and 4 years after ileoureteral replacement secondary to bladder neck obstruction. Ileal substitution of the ureter seems a feasible operation to salvage difficult and recurrent transplant urinary fistulae in exceptional situations when it is impossible to restore urinary continuity using urinary tract tissues.
