Single-stage reconstruction of urinary tract after loop cutaneous ureterostomy

Three patients with four renoureteral units have undergone single-stage reconstruction involving ureteroureterostomy and ipsilateral ureteroneocystostomy following temporary loop cutaneous ureterostomy. Preliminary loop cutaneous ureterostomy diversion allowed adequate ureteral recompensation such that ureteral tapering was unnecessary in any of these cases. Rich collateral circulation as well as strict preservation of adventitial ureteral vasculature allows the performance of upper and lower ureteral procedures in a single session.
