Comparative study of ureteral stripping versus open ureterectomy for nephroureterectomy in patients with transitional carcinoma of the renal pelvis.

Objectives: To evaluate the clinical outcome of nephroureterectomy with endoscopically assisted transurethral ureteral stripping for transitional cell carcinoma of the renal pelvis in a comparative study.

Methods: Sixty patients with localized renal pelvic cancer were enrolled in a prospective comparative nonrandomized study. Of these, 28 patients underwent nephroureterectomy with endoscopically assisted transurethral ureteral stripping and 32 underwent conventional nephroureterectomy with a bladder cuff.
