Modified transurethral technique for the management of distal ureter during laparoscopic assisted nephroureterectomy.

INTRODUCTION: Laparoscopic assisted nephroureterectomy is a well established technique for managing the upper urinary tract urothelial cancer. However, management of the distal ureter remains a controversial issue. We describe a modified method of cystoscopic loop ligation and detachment of the distal ureter. TECHNICAL CONSIDERATION: We performed transperitoneal laparoscopic assisted nephroureterectomy in 13 patients. The lower end of the ureter was managed perurethrally using our modified technique. We circumscribed the ureteric orifice with a bladder cuff using a Collins knife. We ligated the ureteric stump via cystoscope to avoid urine spillage from the upper tract. We achieved the complete excision of the distal ureter with a bladder cuff in all cases with our modified technique. CONCLUSIONS: Our modified technique appears to be a simple, less invasive, and oncologically safe method to manage the distal ureter perurethrally.
