Single waist incision in combination with transurethral oversleeve excision for renal pelvis or ureteral cancer / 中国微创外科杂志

ABSTRACT

Objective To investigate the outcomes of a modified operation for renal pelvis and ureteral cancer.Methods A total of 13 cases of renal pelvis or ureteral cancer was treated in this hospital from January 1998 to July 2005.During the operation,for the first step,the kidney and the majority of the ureter were excised through a waist incision. Then a double-J catheter was inserted into the bladder by way of the residual ureter,and was fastened to the ureter.Afterwards,a transurethral resection of the ureteral orifice and part of bladder mucosa was conducted.Finally,the ureter was pulled down oversleevely into the bladder.Results Except for 1 case of failure of oversleeve excision,in which a re-operation via a lower abdominal incision was required,the surgery was successfully completed in all the other 12 cases.The operation time was 60～90 min(mean,78 min).The intraurethral catheter was indwelled for 7～9 d(mean,7.6 d).The postoperative length of hospitalization was 7～10 d(mean,7.9 d).The 13 cases were followed for 8～18 months(mean,11.5 months).Examinations of exfoliated cells in urine,cystoscopy,and B-ultrasonography found no recurrence.Conclusions Single waist incision combined with transurethral oversleeve resection has smaller surgical trauma,fewer complications,and faster recovery compared with the traditional surgery.
