Late Presentation of Posterior Urethral Valve in a Four-Year-Old Child With Subtle Voiding Symptoms: A Case Report.

A four-year-old male child following an attack of acute pharyngitis was referred to the urology department as having mild voiding difficulty, where posterior urethral valve (PUV) was incidentally diagnosed. Urethrocystoscopy confirmed Type I PUV, which was successfully managed with transurethral laser ablation. This case underscores the importance of evaluating subtle pediatric urinary symptoms to prevent renal complications. Advances in imaging, surgical techniques, and monitoring strategies are critical for effective management. Early diagnosis and timely intervention remain essential to preserve renal and bladder function, emphasizing the need for vigilance in assessing pediatric urinary complaints.
