Only two (6.5%) had pre\u2010natal diagnosis. Twenty\u2010six (83.9%) had one or more complications of the disease at presentation. The mean estimated glomerular filtration rate was 39.5\u2009mL\/min\/1.73\u2009m2<\/jats:sup> (range 4.4\u2013116.0). There was hydronephrosis involving 50 renal units, and vesicoureteral reflux involving 22 renal units. Eight cases required upper tract diversion and four required dialysis prior to definitive catheter ablation. After average follow\u2010up of 12.6 months (range 3\u201322 months), 18 (58.1%) cases had clinical and radiological improvement, 9 (29%) had persisting poor renal function and 4 (12.9%) died from acute renal failure and end\u2010stage renal disease. Associated pulmonary hypoplasia in neonates, presentation at adolescent age, bilateral vesicoureteral reflux and estimated glomerular filtration rate <10.0 at presentation adversely affected outcome. Delayed diagnosis, dearth of facilities and resource deficiency remain a challenge.<\/jats:p><\/jats:sec>Conclusion<\/jats:title>Significant cases of PUV<\/jats:styled-content> present late with complications in our setting and have high morbidity and mortality. The poor outcome may be related to delayed diagnosis, poor renal function at presentation and poor renal support. Improving time to diagnosis and renal support may lead to better outcome.<\/jats:p><\/jats:sec>","DOI":"10.1111\/jpc.12091","type":"journal-article","created":{"date-parts":[[2013,1,18]],"date-time":"2013-01-18T12:20:47Z","timestamp":1358511647000},"page":"115-119","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Posterior urethral valves: Determinants of outcome in a developing country"],"prefix":"10.1111","volume":"49","author":[{"given":"Henrietta U","family":"Okafor","sequence":"first","affiliation":[{"name":"Nephrology Unit Department of Paediatrics University of Nigeria Teaching Hospital Enugu Nigeria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sebastian O","family":"Ekenze","sequence":"additional","affiliation":[{"name":"Sub\u2010Department of Paediatric Surgery University of Nigeria Teaching Hospital Enugu Nigeria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Samuel N","family":"Uwaezuoke","sequence":"additional","affiliation":[{"name":"Nephrology Unit Department of Paediatrics University of Nigeria Teaching Hospital Enugu Nigeria"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2013,1,18]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.juro.2008.03.090"},{"key":"e_1_2_8_3_1","first-page":"2210","article-title":"Posterior urethral valves in Eastern Ontario \u2013 a 30 year perspective","volume":"11","author":"Warren J","year":"2004","journal-title":"Can.
