Abstract:
Objective To report our experience with retroperitoneoscopic nephroureterectomy with excision of a bladder-cuff for renal pelvic and ureteral tumors.Methods Thirty-five patients (21 women and 14 men;mean age,67 years;age range,49 -82 years) with upper urinary tract tumors underwent retro- peritoneal laparoscopic nephrourcterectomy with excision of a bladder-cuff.Of the 35 cases,15 had pelvic tumors and 20 had ureteral tumors;19 cases had the tumors on the right side and 16 on the left.Two cases had ureteral tumors combined with bladder tumors.One case had bilateral ureteral tumors then concomitantly had bladder tumors.The needle electrode was used to circleround incise the bladder thoroughly 0.5 cm away from the ureterostoma.Three trocars in the waist were used for dissecting the kidney;and the ureter was dis- sected as far distally downward.Then an incision of 5-9 cm was created in the lower abdomen to allow dis- section of the distal ureter and bladder-cuff and intact specimen extraction.Results The operation was successful in all 35 patients.The mean operative time was 3.1 h ( range,1.5-6.0h).The mean estimated blood loss was 166 ml (range,20-1600 ml).Four cases received blood transfusion.The patient's activity re- covered in 20-32 h after operation.Postoperative pathology showed transitional cell carcinoma in 30 cases, poorly differentiated adenocareinoma in 2 (ureter),squamous cell carcinoma in 1 (ureter),leiomyosarcoma in 1 (ureter),xanthogranulomatous pyelonephritis in 1.Duodenal leakage occurred in 1 patient who had had dialysis a drainage catheter was placed on the third d after operation,and the patient died of heart failure af- ter 2 months.Postoperative vesical irrigation was performed to prevent tumor recurrence.The mean hospital stay was 11 d.During a mean follow-up of 14 months(range,1-32 months),1 patient developed pelvic me- tastasis and was alive with the tumor.The other 33 patients survived free of tumor to date.No patient had re- current transitional cell carcinoma of the bladder.Conclusions Our data demonstrate that retroperitoneo- scopic nephroureterectomy for renal pelvic and ureteral tumors has shorter incision and more rapid postopera- tive recovery compared with open surgery.Using resectoscope to resect the termination of ureter allows more complete excision of the ureter.
