End-To-Side Versus End-to-End Uretero-Ureteral Anastomosis in Kidney Transplant Recipients With Disused Atrophic Bladder.
BACKGROUND
Extravesical Lich-Gregoir ureteroneocystostomy (UC) is the most widely used method for urinary reconstruction during kidney transplantation. Sometimes it is difficult to perform UC in cases with disused atrophic bladder. Pyelo-ureteral anastomosis (PUA) and uretero-ureteral anastomosis (UUA) may be preferred to UC for these patients.


METHODS
We retrospectively reviewed the charts of 833 kidney transplant recipients operated on by our transplantation team between July 2010 and November 2014. The patients were divided into two groups: Group I consisted of 16 patients who underwent end-to-side UUA and Group II consisted of 20 patients who underwent end-to-end UUA. The two groups were compared in terms of efficacy, safety, and graft function.


RESULTS
As we performed end-to-side UUA as a relatively new technique compared with end-to-end UUA, the post-transplantation follow-up period of Group II was significantly longer than Group I (P = .000), but all the patients in both groups had at least 1 year of follow-up. Because the first two patients in Group II, who underwent native ureteral ligation without nephrectomy, developed hydronephrosis in their native kidneys, requiring nephrectomy in the post-transplantation period, we performed native nephrectomy in all of the remaining patients in this group. That is why the mean operative time was significantly longer in Group II compared with Group I (P = .000). There was no significant difference between the two groups in terms of postoperative surgical complications, post-transplantation urinary infections, and graft function.


CONCLUSIONS
End-to-side UUA without native ureteral ligation is a safe surgical technique for urinary tract reconstruction during kidney transplantation in patients with disused atrophic bladder.
