Background: Posterior urethral valves are the most common cause of obstructive uropathy in male paediatric patients. Objective: To evaluate the clinical presentation, treatment and outcome of 21 PUV patients managed over a 10-year period in University of Uyo Teaching Hospital and KSH Hospital. Methodology: A retrospective review of charts of 21 PUV patients managed between Jan.2012 and Dec. 2022, was done. Data retrieved included age at presentation, clinical features, laboratory and radiological findings, methods of drainage, initial and definitive treatment, complications and outcome. The patients were treated with Mohan’s valvotomy, endoscopic ablation, catheter balloon avulsion and open resection. Results: The age range was 2 weeks to 15years (mean = 4.3 +/-4.4 SD years). All patients had lower urinary tract symptoms and abdominal distension. Seven patients presented with vomiting (33.3%), two had fever (9.5%) and two had visible haematuria (9.5%) in association with voiding symptoms. Electrolytes, urea and creatinine were deranged in 15 patients (71%). Micturating cystourethrogram demonstrated diagnostic features of PUV and Intravenous Urogram were abnormal in all patients. Fifteen patients (71%) had back-pressure effects with vesicoureteral reflux (VUR) and hydroureteronephrosis. Mohan’s valvotomy was used to treat 10 patients (47.6%); endoscopic valve ablation was done in 7 patients (33.3%); catheter balloon avulsion was done in 2 patients (9.5%); and open valve resection was performed in 1 patient (4.7%). Conclusion: Preliminary vesical drainage by urethral catheterization or suprapubic cystostomy improved renal function prior to definitive treatment. The provision of endoscopic facilities for direct vision valve ablation is strongly advocated.
