Transurethral removal of the ureter by the intussusception method in the treatment of renal pelvic and ureteral tumors

Between August 1986 and December 1998, 19 patients who had renal pelvic and upper ureteral tumors were treated with nephrectomy and transurethral removal of the ureter using the intussusception method. Removal of the ureter failed in 5 patients because of excessive ablasion of the ureter or insuffic...

520 |a Between August 1986 and December 1998, 19 patients who had renal pelvic and upper ureteral tumors were treated with nephrectomy and transurethral removal of the ureter using the intussusception method. Removal of the ureter failed in 5 patients because of excessive ablasion of the ureter or insufficient electro-resection around the ipsilateral ureteral orifice. Excluding those patients, the safety of the operation and the intravesical recurrence were compared with the outcome in 12 patients undergoing partial cystectomy for similar tumors. The mean operating time was not significantly shorter with the intussusception method compared with partial cystectomy (190.4 versus 251.3 minutes), but the mean blood loss was significantly smaller (187.5 versus 460.2 ml) and the intussusception method did not require a blood transfusion. The mean term of hospitalization was 20.3 days for patients treated by the intussusception method which was significantly shorter than that for patient undergoing partial cystectomy (25.4 days). Intravesical recurrence was found in seven patients (50%) treated by the intussusception method and the 1- and 5-year recurrence-free rates were 69.2% and 30.8% respectively. There was no significant difference in the recurrence-free rates between the two surgical techniques. These results suggest that the intussusception method is superior to partial cystectomy in decreasing the operating time, blood loss and term of hospitalization. It can be an attractive option in selected cases, without increasing the risk of intravesical recurrence
