Minimal-invasive ileal ureter replacement for the management of multiple ureteral polyps: the initial experience

Purpose To present our initial experience in the management of multiple ureteral polyps with robotic or laparoscopic ileal ureter replacement (IUR). Methods Eight consecutive patients diagnosed with multiple ureteral polyps underwent robotic or laparoscopic IUR between July 2019 and November 2022. Unilateral IUR was performed in 5 patients with polyps in the left ( n = 3) or right ( n = 2) side, and 3 patients with bilateral multiple polyps underwent bilateral IUR. Demographic characteristics, perioperative data and follow-up outcomes were prospectively collected. Results A cohort of 5 male and 3 female patients (11 ureters) with a mean age of 32.8 ± 11.3 years were included. Among these patients, 5 presented with recurrent flank pain, 1 had hematuria, and 2 were asymptomatic. Four patients experienced prior failed surgical interventions. The mean length of diseased ureter was 11.9 ± 4.7 cm, with more than 10 cm in eight sides. All procedures were performed successfully. The mean operation time was 319 ± 87.6 min with 3 patients who simultaneously underwent intraoperative ureteroscopy. The mean length of ileal graft was 23.8 ± 5.8 cm. During the mean follow-up of 20.4 ± 12.8 months, one major complication, specifically incision infection, and four minor complications, including urinary infection ( n = 3) and metabolic acidosis ( n = 1), were observed. All patients presented symptom-free, with improved/stabilized hydronephrosis and no signs of restenosis. Conclusion Robotic or laparoscopic IUR is a feasible, safe, and effective surgical option for patients with long ureteral defects caused by multiple polyps.
