[The persisting mesonephric duct with contralateral cryptorchism and ipsilateral renal aplasia: a case report].
A 30-year-old man with azoospermia underwent an examination for infertility. He had a history of right orchiopexy due to cryptorchism. Radiological examinations showed an absence of the left kidney and the left seminal vesicle. A testicular biopsy revealed normal spermatogenesis in the left testis, but no spermatogenesis in the right testis. The right vasograph demonstrated obstruction of the vas deferens at the inguinal region. The left vasograph showed that the left vas drained into a cystic lesion, which then drained into the bladder neck. The left ureter was connected to this cystic lesion. The final diagnosis was a persistent mesonephric duct which was open to the bladder neck. The pathogenesis of the persistent mesonephric duct combined with the ectopic opening of the ureter and the vas deferens is discussed. The patient was treated by testicular extraction of the testicular sperm, and intracytoplasmic sperm injection.
