Management of urinary extravasation in 18 boys with posterior urethral valves.

ABSTRACTPurpose: Urinary extravasation with associated posterior urethral valves is uncommon and published articles are restricted to case reports. We propose a management algorithm on the basis of presentation of 18 boys with this condition.Materials and methods: In this retrospective review we analyze the clinical features, diagnostic radiological imaging (voiding cystourethrogram and 99mtechnetium mercaptoacetyltriglycine scan) and measured glomerular filtration rate (GFR) for assessment of renal function in boys presenting with posterior urethral valves and urinary extravasation. Indications for surgical intervention and long-term outcome were evaluated. Results are presented as mean ± SD.Results: Patient age at presentation was 4 days (range 1 to 28). Salient features at presentation were abdominal distention in 55.5% of cases, flank mass in 55.5%, respiratory distress in 16.6% and septicemia in 22.2%. Patients were categorized into group 1 with ascites (6 boys) and group 2 without ascites (12). Foll...
