Methods: We retrospectively reviewed 403 patients who underwent RC for bladder cancer between August 2014 and December 2018. The primary objective was to study the effect of stentless UIA on uretero-intestinal anastomosis stricture (UIAS), and the secondary objective was to evaluate the association between stentless UIA and other complications, including paralytic ileus, febrile urinary tract infection (UTI), and urine leakage. Kaplan\u2013Meier survival analysis was used to estimate UIAS-free survival, and Cox proportional hazard models were applied to identify factors associated with the risk of UIAS. Results: Among 403 patients with 790 renal units, UIAS was identified in 39 (9.7%) patients and 53 (6.7%) renal units. Forty-four (83.0%) patients with UIAS were diagnosed within 6 months. The 1- and 2-year overall UIAS-free rates were 93.9% and 92.7%, respectively. Paralytic ileus was identified in 105 (26.1%) patients and resolved with supportive treatment. Febrile UTI occurred in 57 patients (14.1%). However, there was no leak of the UIA. Conclusions: Stentless UIA during RC with an ileal orthotopic neobladder is a feasible and safe surgical option. Further prospective randomized trials are required to determine the clinical usefulness of stentless UIA during RC.<\/jats:p>","DOI":"10.3390\/jcm10225372","type":"journal-article","created":{"date-parts":[[2021,11,18]],"date-time":"2021-11-18T08:53:56Z","timestamp":1637225636000},"page":"5372","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Feasibility and Safety of Stentless Uretero-Intestinal Anastomosis in Radical Cystectomy with Ileal Orthotopic Neobladder"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3030-0405","authenticated-orcid":false,"given":"Chung Un","family":"Lee","sequence":"first","affiliation":[{"name":"Department of Urology, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul 06351, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jong Hoon","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Urology, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul 06351, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dong Hyeon","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Urology, Ewha Womans University Medical Center, Ewha Womans University School of Medicine, Seoul 07985, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wan","family":"Song","sequence":"additional","affiliation":[{"name":"Department of Urology, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul 06351, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,11,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"82","DOI":"10.1016\/j.eururo.2020.03.055","article-title":"European Association of Urology Guidelines on Muscle-invasive and Metastatic Bladder Cancer: Summary of the 2020 Guidelines","volume":"79","author":"Witjes","year":"2021","journal-title":"Eur.
