Anterior urethral valve as a cause of end-stage renal disease

Although posterior urethral valves are predominant as a cause of obstructiv e uropathy in children, anterior urethral valves may also appear as the und erlying etiologic factor in end-stage renal disease that results from obstr uction. Two cases are presented of anterior urethral valve patients that we re admitted with end-stage renal disease. The first case was successfully t reated with diverticulectomy and urethral reconstruction in preparation for renal transplantation. The second case, however, had been on cystostomy dr ainage for 6 years and also had a contracted bladder. A more extensive lowe r urinary tract reconstruction was delayed. Children with poor stream and r ecurrent infections should be evaluated carefully and anterior urethral val ve or diverticula should be considered in differential diagnosis of obstruc tive lesions.
