ABSTRACT
Objective To examine the feasibility of using the serous-lined tunnel technique for orthotopic neobladder, continent cutaneous diversion and ureteral replacement by the intestinal segment. Methods In 31 patients of orthotopic ileal neobladder, the serous-lined tunnel techniques were used for antirefluxing ureteral implantation: In 13 patients of continent ileal pouch, the techniques were adopted for continent-valve construction and for uretersl implantation: In 3 patients (with lower ureteric cancer), the same techniques were applied for constructing the ileal ureters with a proximal antirefluxing mechanism. Results With a mean follow-up of 27 mon( 12-132 mon), 88 ureters implanted into ileal neobladders or continent pouches functioned well with neither obstruction nor reflux: 12 in 13 continent valves functioned well with no incontinence. 3 patients with ileal ureters showed no ileo-ureteric reflux and had reduced hydronephrosis comparing to that of before surgery.Conclusions Ureteral reimplantation and continent valve formation achieved by adopting the serouslined tunnel technique provide satisfactory results. The versatility of the technique is obvious in the present experience and the creative application of the serous-lined tunnel technique should be possible in urinary reconstruction.
