Majority of reported cases of genitourinary causes of ascites were due to posterior urethral valve. Here, we report a 6-month-old boy who presented with progressive tense ascites and peritonitis attributed by unilateral left distal ureteric obstruction and acute pyonephrosis. He underwent left nephrostomy placement, after which there was a remarkable improvement of ascites. He then underwent left ureteral diversion procedure a month later with a tentative plan for ureteral reanastomosis in 6 months. To date, there are no reports describing ascites secondary to distal ureteric obstruction beyond the neonatal period. The objective of this case report is to highlight unilateral urinary tract obstruction as a potential cause of transudative ascites. Additionally, the superimposed infection in the obstructed collecting system can lead to acute peritonitis likely due to translocation of bacteria into the peritoneal cavity.<\/jats:p>","DOI":"10.1136\/bcr-2021-243949","type":"journal-article","created":{"date-parts":[[2022,1,17]],"date-time":"2022-01-17T10:46:36Z","timestamp":1642416396000},"page":"e243949","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Unusual case of ascites secondary to unilateral distal ureteric obstruction in an infant"],"prefix":"10.1136","volume":"15","author":[{"given":"Amirtha Vahini","family":"Chinnadurai","sequence":"first","affiliation":[{"name":"Department of Paediatrics, Universiti Kebangsaan Malaysia Medical Centre, Cheras, Kuala Lumpur, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joyce Soo Synn","family":"Hong","sequence":"additional","affiliation":[{"name":"Department of Paediatrics, Universiti Kebangsaan Malaysia Medical Centre, Cheras, Kuala Lumpur, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hasniah","family":"Abdul Latif","sequence":"additional","affiliation":[{"name":"Department of Paediatrics, Universiti Kebangsaan Malaysia Medical Centre, Cheras, Kuala Lumpur, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2022,1,17]]},"reference":[{"key":"2025082802334736000_15.1.e243949.1","first-page":"55","article-title":"Pediatric ascites revisited","volume":"1","author":"Tomar","year":"2016","journal-title":"Int J Gastroenterol Hepatol Transpl Nutr"},{"key":"2025082802334736000_15.1.e243949.2","doi-asserted-by":"crossref","first-page":"345","DOI":"10.1111\/j.1651-2227.1966.tb17665.x","article-title":"Neonatal ascites and urinary-tract obstruction","volume":"55","author":"Linde","year":"1966","journal-title":"Acta Paediatr Scand"},{"key":"2025082802334736000_15.1.e243949.3","first-page":"1","article-title":"Neonatal urinary ascites: a report of three cases","volume":"2015","author":"Solarin","year":"2015","journal-title":"Case Rep Nephrol"},{"key":"2025082802334736000_15.1.e243949.4","doi-asserted-by":"crossref","first-page":"192","DOI":"10.1016\/j.urology.2018.03.026","article-title":"Urinary ascites secondary to bilateral mid-ureteral stenosis in a neonate","volume":"118","author":"Matsumoto","year":"2018","journal-title":"Urology"},{"key":"2025082802334736000_15.1.e243949.5","doi-asserted-by":"crossref","unstructured":"Lange-Sperandio B .
