Usually, the penile urethra is hypoplastic, and urine is passed through the perineal channel. A 12-year-old boy with Y-duplication urethra presented with well-developed penile and perineal channels. The perineal channel was opening within the anal sphincter instead of opening within the rectum. It appears that high resistance offered by the anal sphincter redirected the urinary stream through the penile channel, thereby leading to its adequate development. On this basis, we propose a new hypothesis of \u201csiphoning-disuse atrophy\u201d to explain the morphogenesis of Y-duplication of the urethra. Clinical significance of distinguishing between pre- and postsphincteric opening of the perineal channel is emphasized.<\/jats:p>","DOI":"10.4103\/jiaps.jiaps_238_25","type":"journal-article","created":{"date-parts":[[2025,11,5]],"date-time":"2025-11-05T08:00:30Z","timestamp":1762329630000},"page":"113-115","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Y-duplication of the Urethra with an Unusual Morphology (Type A4D10): Insight into the Pathogenesis"],"prefix":"10.4103","volume":"31","author":[{"given":"Hasan","family":"Sumayya","sequence":"first","affiliation":[{"name":"Department of Pediatric Surgery, Government Cuddalore Medical College, Chidambaram, Tamil Nadu, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Venkatachalam","family":"Raveenthiran","sequence":"additional","affiliation":[{"name":"Department of Pediatric Surgery, Government Cuddalore Medical College, Chidambaram, Tamil Nadu, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2025,11,4]]},"reference":[{"key":"R1-20260420","doi-asserted-by":"crossref","first-page":"1170","DOI":"10.1111\/iju.15536","article-title":"A novel alpha-numeric classification of urethral duplication and triplication","volume":"31","author":"Raveenthiran","year":"2024","journal-title":"Int J Urol"},{"key":"R2-20260420","doi-asserted-by":"crossref","first-page":"1404947","DOI":"10.3389\/fped.2024.1404947","article-title":"Urethral multiplicity in boys: Systematic review of case reports and case series from the last 15 years","volume":"12","author":"Gozar","year":"2024","journal-title":"Front Pediatr"},{"key":"R3-20260420","doi-asserted-by":"crossref","first-page":"21","DOI":"10.1186\/s43159-023-00252-0","article-title":"The so-called Y-type urethral duplication: Anatomical insights through controversial terminology","volume":"19","author":"AbouZeid","year":"2023","journal-title":"Ann Pediatr Surg"},{"key":"R4-20260420","doi-asserted-by":"crossref","first-page":"179","DOI":"10.1148\/119.1.179","article-title":"Duplication of the urethra","volume":"119","author":"Effmann","year":"1976","journal-title":"Radiology"},{"key":"R5-20260420","doi-asserted-by":"crossref","first-page":"414.e1","DOI":"10.1016\/j.jpurol.2021.02.008","article-title":"Working classification and the quest for an effective, reconstructive management strategy in Y duplication of male urethra","volume":"17","author":"Kurian","year":"2021","journal-title":"J Pediatr Urol"},{"key":"R6-20260420","doi-asserted-by":"crossref","first-page":"1492","DOI":"10.1016\/j.urology.2014.09.002","article-title":"Congenital posterior urethroperineal fistula: A review and report of the 25th case in literature","volume":"84","author":"Bello","year":"2014","journal-title":"Urology"},{"key":"R7-20260420","doi-asserted-by":"crossref","first-page":"277","DOI":"10.1016\/S0090-4295(96)00171-9","article-title":"Congenital posterior urethral perineal fistulae: A unique form of urethral duplication","volume":"48","author":"Wagner","year":"1996","journal-title":"Urology"},{"key":"R8-20260420","doi-asserted-by":"crossref","first-page":"30","DOI":"10.1016\/j.jpurol.2020.11.032","article-title":"Congenital Y-urethra \u2013 A diagnostic and therapeutic challenge","volume":"17","author":"Lorenz","year":"2021","journal-title":"J Pediatr Urol"}],"container-title":["Journal of Indian Association of Pediatric Surgeons"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ovid.com\/10.4103\/jiaps.jiaps_238_25","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,18]],"date-time":"2026-08-18T15:43:22Z","timestamp":1787067802000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ovid.com\/10.4103\/jiaps.jiaps_238_25"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,11,4]]},"references-count":8,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2026]]}},"URL":"https:\/\/doi.org\/10.4103\/jiaps.jiaps_238_25","relation":{},"ISSN":["0971-9261","1998-3891"],"issn-type":[{"value":"0971-9261","type":"print"},{"value":"1998-3891","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,11,4]]},"assertion":[{"value":"2025-07-13","name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-08-31","name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}}]}}
