For lateral bladder wall tumors, obturator nerve stimulation can trigger sudden adductor contractions, raising the risk of perforation, hemorrhage, incomplete resection, and poor specimen quality. We evaluated the impact of obturator nerve block (ONB) on specimen quality and perioperative complications. Methods: In this single-center retrospective study, patients with lateral wall tumors treated by TURBT between October 2022 and December 2024 were divided into an ONB group (spinal anesthesia plus ONB) and a non-ONB group (spinal anesthesia alone). Specimen quality, perioperative complications, and 12-month recurrence were analyzed. Results: In this retrospective cohort of 219 patients (135 ONB, 84 non-ONB), high-quality specimens were more frequent with ONB (71.1% vs. 35.7%, p &lt; 0.001). No perforations occurred with ONB versus 5 (6.0%) without (p = 0.008); hematuria (11.1% vs. 28.6%, p = 0.002) and 12-month recurrence (4.4% vs. 16.7%, p = 0.005) were also lower. Conclusions: ONB added to spinal anesthesia during TURBT for lateral wall tumors was associated with improved specimen quality and fewer perioperative complications. The lower recurrence rate should be considered hypothesis-generating, given the retrospective design and the small number of recurrence events; prospective studies are needed.<\/jats:p>","DOI":"10.3390\/jcm15145473","type":"journal-article","created":{"date-parts":[[2026,7,13]],"date-time":"2026-07-13T08:53:58Z","timestamp":1783932838000},"page":"5473","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Obturator Nerve Block Is Associated with Improved Histopathological Specimen Quality and Fewer Perioperative Complications During TURBT for Lateral Bladder Wall Tumors"],"prefix":"10.3390","volume":"15","author":[{"given":"Drago\u0219 Florin","family":"Vasile","sequence":"first","affiliation":[{"name":"Department of Urology, University of Medicine and Pharmacy of Craiova, 200349 Craiova, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nelu Vivi","family":"C\u0103lina","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology and Intensive Care, Clinical County Emergency Hospital of Craiova, 200349 Craiova, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mihnea","family":"Me\u0219in\u0103","sequence":"additional","affiliation":[{"name":"Department of Urology, University of Medicine and Pharmacy of Craiova, 200349 Craiova, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-1971-8729","authenticated-orcid":false,"given":"Mihai Alexandru","family":"Radu","sequence":"additional","affiliation":[{"name":"Department of Urology, University of Medicine and Pharmacy of Craiova, 200349 Craiova, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"George G.","family":"Mitroi","sequence":"additional","affiliation":[{"name":"Department of Dermatology, University of Medicine and Pharmacy of Craiova, 200349 Craiova, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6875-1041","authenticated-orcid":false,"given":"Alex Emilian","family":"Stepan","sequence":"additional","affiliation":[{"name":"Department of Pathology, University of Medicine and Pharmacy of Craiova, 200349 Craiova, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cosmin Vasile","family":"Obleag\u0103","sequence":"additional","affiliation":[{"name":"Department of Surgical Oncology, University of Medicine and Pharmacy of Craiova, 200349 Craiova, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Drago\u0219 George","family":"Popa","sequence":"additional","affiliation":[{"name":"Department of Plastic Surgery, University of Medicine and Pharmacy of Craiova, 200349 Craiova, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stan Marius","family":"Doru","sequence":"additional","affiliation":[{"name":"Department of Urology, Clinical County Emergency Hospital of Constan\u021ba, 900591 Constan\u021ba, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"George F.","family":"Mitroi","sequence":"additional","affiliation":[{"name":"Department of Urology, University of Medicine and Pharmacy of Craiova, 200349 Craiova, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,7,13]]},"reference":[{"key":"ref_1","first-page":"229","article-title":"Global cancer statistics 2022: GLOBOCAN estimates of incidence and mortality worldwide for 36 cancers in 185 countries","volume":"74","author":"Bray","year":"2024","journal-title":"CA Cancer J.
