PURPOSE: Ureteral ectopia is frequently associated with dysplasia of the associated renal segment in girls with ureteral duplication. However, single system ureteral ectopia is an uncommon anomaly more frequently noted in boys. We report on 6 boys with single system ureteral ectopia into the prostatic urethra above the verumontanum, who presented with radiological and clinical findings of bladder outlet obstruction.
MATERIALS AND METHODS: Antenatal ultrasound in 3 boys demonstrated renal abnormalities and postnatal studies suggested the diagnosis of posterior urethral valve obstruction. Older boys presented with symptoms suggestive of bladder outlet obstruction.
RESULTS: An ectopic ureter inserting into the prostatic urethra was noted in all 6 boys. The distal ureter was dilated elevating the bladder neck causing outlet obstruction. Surgical management consisted of nephrectomy and transurethral endoscopic incision of the distal ureter or nephroureterectomy with reconstruction of the prostatic urethra. In 2 younger boys voiding dysfunction with inability to empty developed.
CONCLUSIONS: Single system ectopic ureters in boys may present with symptomatic and radiological findings resembling posterior urethral valves. Surgical treatment should include nephroureterectomy with reconstruction of the hypoplastic prostate. Some patients may have later voiding dysfunction.
