title: Müllerian remnant causing bladder outlet obstruction.
abstract: Less than one-third of patients with persistent müllerian duct remnants develop bladder outlet obstructive symptoms. We report on two cases of bladder outlet obstruction caused by massive dilatation of persistent müllerian duct remnants. Such structures should be suspected when outlet obstructive symptoms occur in patients with hypospadias and/or undescended gonads. Care should be taken to identify possible urethral obstruction distal to the prostatic urethra as a cause of gross enlargement of persistent müllerian duct remnants.
