PURPOSE: Ureteroneocystostomy is the standard mode of establishing urinary drainage in renal transplantation. However, donor-to-recipient ureteroureterostomy may be considered in the presence of a challenging bladder or an augmented bladder, or when the donor ureter might be compromised or is too short. This approach also preserves a nonrefluxing system with an orthotopic ureteral orifice.
MATERIALS AND METHODS: We retrospectively reviewed the records of all pediatric renal transplantations in which ureteroureterostomy was performed at a single tertiary care pediatric center over the 12-year period from 2004 to 2015. Ureteroureterostomy was performed in end-to-side fashion from donor-to-recipient ureter. Patients with a history of symptomatic vesicoureteral reflux were excluded from ureteroureterostomy. Parameters were reviewed, including age, gender, source of renal transplantation (deceased or living donor), indications for ureteroureterostomy and complications.
RESULTS: Primary ureteroureterostomy was performed at 23 of the 213 renal transplantations (10.8%). At transplantation mean ± SD age was 11.7 ± 4.9 years and mean weight was 33.5 ± 18.9 kg. Two secondary ureteroureterostomies were done to salvage the ureter due to complications after ureteroneocystostomy. Of the patients 60% and 40% underwent ureteroureterostomy during deceased and living donor renal transplantation, respectively. The most common indications included a challenging small bladder due to anuria, a valve bladder and a neurogenic augmented bladder. Two urinary leaks (8%) occurred and no allografts were lost.
CONCLUSIONS: Ureteroureterostomy is a safe alternative to standard ureteroneocystostomy in renal transplantation. Ureteroureterostomy should be considered a primary option in certain complex situations and secondarily as a salvage procedure when ureteral problems develop after ureteroneocystostomy in patients who undergo renal transplantation.
