title: [Single-stomal ureterostomy by extraperitoneal approach].
abstract: Single-stomal ureterostomy such as double barreled ureterocutaneostomy and cutaneous transureteroureterostomy have usually been performed by transperitoneal approach. However, extraperitoneal method is preferable since the patients for whom ureterocutaneostomy is indicated usually have a deteriorating general condition. We have reported single-stomal ureterocutaneostomy which can be done extraperitoneally. A total of thirteen patients, one man and twelve women, for whom permanent urinary diversion was indicated, have undergone this extraperitoneal ureterocutaneostomy for February 1988 to June 1994. Those with retroperitoneal lesions or with a history of paraaortic radiotherapy were excluded. The mean age was 61.7 (range: 42-76). The reasons for urinary diversion were vesicovaginal fistula in seven, obstructive nephropathy in four, rectovesical fistula in one and postoperative urine leak from the bladder in one. All patients had been treated for malignant diseases and had undergone transperitoneal surgery. Six patients had colostomy and ten had clinically evident recurrent diseases. In the operation, left ureter was dissected and severed extraperitoneally through left paramedian incision or left lumbotomy. The ureteral end was pushed to the right in a retroperitoneal tunnel created by blunt dissection. Then the ureter was picked up through the contralateral retroperitoneal approach. After both ureters were exposed, ureterocutaneostomy was made in right hypogastrium. Transureteroureterstomy with end-cutaneous ureterostomy, double barreled ureterocutaneostomy and ureteroureterostomy with loop ureterostomy were done in six, four and three patients, respectively. The mean operative time was 119 (range: 75-175) minutes and the mean intraoperative blood loss was 210 (range: 48-682) grams. Arrhythmia developed during retroperitoneal manipulation in one patient for whom the operation was done under spinal anesthesia.(ABSTRACT TRUNCATED AT 250 WORDS)
