Correlation between operative procedures for pelviureteral carcinoma and the postoperative occurrence of bladder carcinoma / 中华泌尿外科杂志

ABSTRACT

Objective To evaluate the correlation betwe en operative procedures for pelviureteral carcinoma and the occurrence of postop ertive occurrence of bladder carcinoma. Methods 94 cases of pelviureteral carcinoma with postopertive occurrence of bladder carcinoma we re retrospectively studied. Results With nephrouretectom y without cuff resection of the bladder,the postoperative occurrence of bladder carcinoma was 54.5%(6/11),being obviously higher than nephroureterectomy with pa rtial bladder resection (23.5%,12/51) or nephroureterectomy with bladder mucosal cuff resection (33.3%,3/9,P0.05).The lap between the primary ope ration and the occurrence of bladder carcinoma was usually short and the occurre nce was mostly on the same affected side.In pelviureteral carcinoma with multior gan involvement,the postopertive occurrence of bladder carcinoma was as high as 72.2%(13/15) in spite of nephroureterectomy with partial resection of the bladde r . Conclusions Cuff resection of the bladder on the same side is the key point to prevent postoperative occurrence of bladder carcinoma.T he improved bladder mucosa cuff technique is a sound procedure to prevent tumor cell implantation.
