Single ectopic ureter masquerading as ureterocele in incontinent male.

A seven-year-old body with diurnal and nocturnal incontinence was found to have a dysplastic left kidney and an associated ectopic ureter in a single, system which opened beside the verumontanum. An intravesical bulge was identified which resembled a ureterocele but was, in fact, a dilated ectatic lower ureter proximal to the orifice of the ectopic opening bulging posteriorly into the bladder. This bulge masqueraded as a ureterocele.
