The increasing use of prenatal ultrasound has contributed to the early diagnosis of posterior urethral valves (PUV), a condition associated with a severe prognosis, as approximately one-fifth of affected patients develop chronic kidney disease. Early diagnosis and intervention\u2014namely, valve ablation\u2014provide obstruction alleviation and renal function preservation. Therefore, it is uncommon for patients to be diagnosed in adolescence or adulthood, when patients usually present with frequency, voiding dysfunction, daytime incontinence, enuresis, recurrent urinary tract infections, and renal insufficiency. Case Presentation: We present a 14-year-old adolescent with recurrent urinary tract infections. A thorough medical history, clinical examination, and standard imaging revealed bilateral vesicoureteral reflux and posterior urethral valves. The patient underwent urethrocystoscopy for diagnostic and therapeutic purposes and posterior urethral valve ablation. Despite these interventions, the persistence of his symptoms necessitated endoscopic correction of the vesicoureteral reflux and circumcision. During the 2-year follow-up, the patient remained asymptomatic. Conclusions: Symptomatic adolescent boys should undergo a standard urinary evaluation to identify undiagnosed congenital urinary tract diseases and maintain renal and bladder function.<\/jats:p>","DOI":"10.3390\/reports9010076","type":"journal-article","created":{"date-parts":[[2026,3,3]],"date-time":"2026-03-03T17:01:42Z","timestamp":1772557302000},"page":"76","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Delayed Diagnosis of Posterior Urethral Valves in a 14-Year-Old Adolescent"],"prefix":"10.3390","volume":"9","author":[{"given":"Christos","family":"Kyriopoulos","sequence":"first","affiliation":[{"name":"Department of Urology, Agia Sofia Children\u2019s Hospital, 11527 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9372-155X","authenticated-orcid":false,"given":"Anna","family":"Papakonstantinou","sequence":"additional","affiliation":[{"name":"Department of Urology, Agia Sofia Children\u2019s Hospital, 11527 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Evangelos","family":"Fragkiadis","sequence":"additional","affiliation":[{"name":"First Department of Urology, Medical School, National and Kapodistrian University of Athens, 11527 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1820-9027","authenticated-orcid":false,"given":"Napoleon","family":"Moulavasilis","sequence":"additional","affiliation":[{"name":"First Department of Urology, Medical School, National and Kapodistrian University of Athens, 11527 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Panagiotis","family":"Mitsos","sequence":"additional","affiliation":[{"name":"Department of Urology, Agia Sofia Children\u2019s Hospital, 11527 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,3,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"560","DOI":"10.1038\/pr.2014.134","article-title":"Epidemiology and Demography of Recently Diagnosed Cases of Posterior Urethral Valves","volume":"76","author":"Thakkar","year":"2014","journal-title":"Pediatr.
