Introduction: Minimally invasive surgical techniques are currently used for numerous urologic disorders and generally offer decreased morbidity and equivalent outcomes compared with open surgery. There is a relative paucity of data on robot-assisted ureteral re-implantation (RAUR) in adult patients for benign stricture disease.
Patients and methods: We retrospectively reviewed our recent experience with mid-/distal ureteral reconstruction at a single tertiary-care center. From 2010 to 2012, 13 consecutive patients presenting with benign obstruction of mid-/distal ureters were managed with RAUR.
Results: In all cases the operative procedure was undertaken with six-port transperitoneal access, and all procedures were completed robotically. All ureters (left, n=5; right, n=7; bilateral, n=1) were re-implanted in a standard Bricker fashion into the dome of the bladder with (n=8) or without (n=6) a psoas hitch. Catheters were removed 4-11 days postoperatively, and all cystograms were negative for leak. Stents were removed 14-48 days after surgery. All were negative for hydronephrosis. Average follow-up was 10 (range, 2-20) months. There were two grade 1, two grade 2, two grade 3, and no grade 4 or 5 complications in 3 patients.
Conclusions: RAUR is a safe and effective procedure. Extensive laparoscopic lysis of adhesions represents the primary challenge to an otherwise straightforward minimally invasive surgery. At our institution, RAUR has replaced open ureteral re-implantation as the preferred treatment for benign mid-/distal ureteral stricture disease.
