The Pull-through Anastomosis of Ureter to Enteric Conduit (PAUTEC): A Novel Technique for Urinary Diversion

To describe and illustrate a novel technique of uretero-ileal anastomosis for use in urinary diversion - the Pull-through Anastomosis of Ureter To Enteric Conduit (PAUTEC). A second objective was to evaluate the surgical outcomes of the PAUTEC anastomosis.Our novel anastomotic technique was described step-by-step and visually depicted with illustrations and the accompanying narrated video. Additionally, to evaluate safety and efficacy, a retrospective review of a prospectively maintained database was performed. Patients who underwent radical cystectomy alone or during pelvic exenteration, with ileal conduit diversion incorporating PAUTEC, 2016-2020 with ≥6 months follow-up were included. Surgical outcomes and renal function were analysed.PAUTEC anastomosis was performed on 43 ureters in 23 patients. Mean age was 66 years [50-80] and 21 of 23 patients were male. One patient had a conservatively-managed small urine leak. No ureteric strictures have been identified to date. Mean serum creatinine was 1.15 mg/dL [0.69-2.08] (102umol/L, range 61-184 umol/L) preoperatively, and 1.09 mg/dL [0.61-2.59] (96.3 umol/L, range 54-229 umol/L) at follow-up, demonstrating no significant change (P= .26, paired t-test). Mean follow-up was 15 months [6-44].A PAUTEC technique of uretero-ileal anastomosis is feasible and technically straightforward, with satisfactory outcomes observed to date.
