Native ureteroureterostomy in renal allograft recipient surgery: A single-center 5-year experience.

In renal transplant, surgeons use a myriad of ureteral anastomotic techniques. Although ureteroneocystostomy (UNC) using Lich-Gregoir extravesical anastomosis is used most commonly, ureteroureterostomy with native ureter has its own importance in certain situations. We retrospectively reviewed records of patients who underwent renal transplantation at our center from March 2011 to February 2016. Records of patients who underwent ureteroureterostomy with the native ureter were reviewed for the indications and complications of the procedure. Of 1050 renal transplants during the study period, 32 patients underwent native ureteroureterostomy. Among these 32 patients, 20 patients were planned preoperatively for native ureteroureterostomy (elective), and intraoperative decision was made in 12 patients (emergency). On follow-up, only one patient had ureteral obstruction due to kink just distal to ureteroureterostomy and was managed by double-J stenting. Other patients had an expected postoperative course. In our experience, ureteroureterostomy with native ureter is technically and functionally good option for ureteric reimplantation in kidney transplant patients. It can be used selectively for elective and emergency situations where UNC is not possible. Hence, the kidney transplant surgeon should be well versed with both techniques.
