Recurrent epididymo-orchitis caused by posterior urethral valve associated with imperforate anus.

Epididymo-orchitis is an uncommon complication of imperforate anus. A 14-year-old boy who received surgical repair for imperforate anus was diagnosed with right epididymo-orchitis. Intravenous pyelography showed a right solitary kidney. Posterior urethral valve, reflux of contrast medium to the ejaculatory duct and incomplete duplicate urethra were suspected from voiding cystourethrography. Valve ablation was performed to prevent the recurrence of epididymo-orchitis. Improvement of urinary force was achieved and the patient has been free of recurrence during a 2-year follow up. For the patient with imperforate anus, we should evaluate not only anorectal function, but also the genitourinary tract in order to preserve renal function and fertility.
