A multigravida at 16\u2009weeks' gestation referred for an abdominal cyst was found to have a large urinary bladder along with another dilated cystic structure between the fetal legs (sandwich sign), bilateral echogenic kidneys, and anhydramnios, features suggestive of congenital megalourethra. Medical termination of pregnancy was performed. The male abortus was noted to have a massively distended bladder and a dilated penile urethra. Another patient referred in view of suspected bladder outlet obstruction was diagnosed to have a megalourethra on imaging at our center using the sandwich sign. In severe oligohydramnios the \u201csandwich sign\u201d helps in \u201cruling in\u201d the diagnosis of megalourethra and ruling out the common differential diagnosis of a posterior urethral valve.<\/jats:p>","DOI":"10.1002\/jcu.24078","type":"journal-article","created":{"date-parts":[[2025,5,15]],"date-time":"2025-05-15T05:26:27Z","timestamp":1747286787000},"page":"1897-1901","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["<scp>CONGENITAL MEGALOURETHRA<\/scp>: Lower Urinary Tract Obstruction With \u201cThe Sandwich Sign\u201d"],"prefix":"10.1002","volume":"53","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2612-0302","authenticated-orcid":false,"given":"Ishita","family":"Agarwal","sequence":"first","affiliation":[{"name":"Apollo Centre for Fetal Medicine, Indraprastha Apollo Hospitals  New Delhi India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akshatha","family":"Prabhu","sequence":"additional","affiliation":[{"name":"Apollo Centre for Fetal Medicine, Indraprastha Apollo Hospitals  New Delhi India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Srishti","family":"Chandra","sequence":"additional","affiliation":[{"name":"Apollo Centre for Fetal Medicine, Indraprastha Apollo Hospitals  New Delhi India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shobhna","family":"Sengar","sequence":"additional","affiliation":[{"name":"Obstetrics and Gynecology Jeevan Hospital  Ghaziabad India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anita","family":"Kaul","sequence":"additional","affiliation":[{"name":"Apollo Centre for Fetal Medicine, Indraprastha Apollo Hospitals  New Delhi India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,5,15]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/uog.8862"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.15557\/JoU.2019.0045"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.7863\/jum.1989.8.11.613"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.1186\/s43159-023-00265-9"},{"key":"e_1_2_11_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-319-43310-3"},{"key":"e_1_2_11_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.amsu.2022.104926"},{"key":"e_1_2_11_8_1","doi-asserted-by":"publisher","DOI":"10.1002\/uog.26106"},{"key":"e_1_2_11_9_1","doi-asserted-by":"publisher","DOI":"10.7863\/ultra.14.12064"},{"key":"e_1_2_11_10_1","first-page":"1067","article-title":"Obstructive Uropathy in Childhood; Diagnosis and Surgical Management","volume":"54","author":"Nesbit R.
