Unusual variant of inverted Y ureteral duplication with an ipsilateral seminal vesicle cyst and renal dysgenesis

摘要

Inverted Y malformation is a rare variant of ureteral duplication with a marked female predominance. We describe a case of inverted Y ureteral duplication with concurrent ectopic ureteral insertion into a seminal vesicle cyst, a ureterocoele and renal dysgenesis, which occurred in a 29-year-old man with lower urinary tract symptoms, haematospermia and postcoital discomfort. To our knowledge, this is the first reported case with this constellation of urogenital abnormalities.
