Variant forms associated with hypoplastic kidneys and ectopic ureteral insertion in the vagina may require nephrectomy because of persistent urinary incontinence. In such cases, urinary drainage through a vaginal opening permits direct ureteral access via vaginoscopy without the size limitations associated with transurethral cystoscopy. Therefore, retrograde catheter placement is technically feasible in patients with OHVIRA syndrome. Consequently, OHVIRA is a particularly suitable indication for ureteral catheterization. Fluorescent ureteral catheters, which were recently introduced in surgery for adults, enable real\u2010time intraoperative visualization of the ureter and may further enhance surgical safety. We report a case involving laparoscopic nephrectomy for OHVIRA syndrome with an ectopic ureter and severely hypoplastic kidney in a pediatric patient. The ectopic ureteral orifice was successfully identified during vaginoscopy when the patient was 5 years of age; therefore, retrograde placement of a fluorescent ureteral catheter was feasible. Intraoperative fluorescence enabled the reliable identification of both the ureter and small renal remnant, thus facilitating safe dissection and resection. This case demonstrates that retrograde placement of a fluorescent ureteral catheter via vaginoscopy is feasible and useful for pediatric patients with OHVIRA syndrome who require nephrectomy. This technique may improve intraoperative ureteral visualization and surgical safety; therefore, it should be considered for selected patients with ectopic ureteral drainage.<\/jats:p>","DOI":"10.1155\/criu\/9979542","type":"journal-article","created":{"date-parts":[[2026,5,21]],"date-time":"2026-05-21T08:39:13Z","timestamp":1779352753000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Fluorescent Ureteral Catheter\u2013Assisted Laparoscopic Nephrectomy for a Pediatric Patient With Obstructed Hemivagina and Ipsilateral Renal Anomaly Syndrome"],"prefix":"10.1155","volume":"2026","author":[{"given":"Masaki","family":"Shinohara","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9877-8571","authenticated-orcid":false,"given":"Kenichiro","family":"Konishi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shigemitsu","family":"Kojima","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hisashi","family":"Kanda","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takeshi","family":"Yamaguchi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akira","family":"Nishi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2026,5,21]]},"reference":[{"key":"e_1_2_12_1_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.fertnstert.2006.11.015"},{"key":"e_1_2_12_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpurol.2014.12.004"},{"key":"e_1_2_12_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.epsc.2019.101358"},{"key":"e_1_2_12_4_2","doi-asserted-by":"publisher","DOI":"10.4103\/0971-9261.129607"},{"key":"e_1_2_12_5_2","first-page":"215","article-title":"Use of Laparoscopy in Pediatric Urology","volume":"7","author":"Kim C.","year":"2005","journal-title":"Reviews in Urology"},{"key":"e_1_2_12_6_2","doi-asserted-by":"crossref","DOI":"10.1007\/978-88-470-2923-1","volume-title":"Retroperitoneoscopy and Extraperitoneal Laparoscopy in Pediatric and Adult Urology","author":"Caione P.","year":"2003"},{"key":"e_1_2_12_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jmig.2021.04.004"},{"key":"e_1_2_12_8_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00464-021-08538-3"},{"key":"e_1_2_12_9_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00404-021-06103-w"},{"key":"e_1_2_12_10_2","doi-asserted-by":"publisher","DOI":"10.3390\/medicina60121922"},{"key":"e_1_2_12_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpedsurg.2006.01.021"},{"key":"e_1_2_12_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejogrb.2022.06.013"},{"key":"e_1_2_12_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0025-6196(25)07942-X"},{"key":"e_1_2_12_14_2","doi-asserted-by":"publisher","DOI":"10.1097\/00004728-200011000-00001"},{"key":"e_1_2_12_15_2","volume-title":"EAU Guidelines on Paediatric Urology: Ectopic Ureter","author":"European Association of Urology","year":"2026"},{"key":"e_1_2_12_16_2","first-page":"6603","article-title":"High Pressure Vaginography to Diagnose Vaginal Ureteral Ectopia in Patients With Continuous Urinary Incontinence","volume":"20","author":"Zuckerman J.
