We examined 11 patients with acquired obstructive azoospermia resulting from irreparable obstruction of 1 vas deferens and severe damage to the contralateral testis. All of the patients underwent transseptal crossed vasovasostomy with no morbidity. Of 8 patients evaluated with postoperative semen analyses 4 (50 per cent) demonstrated total sperm counts of 29 to 205 million and 2 pregnancies (25 per cent) have been reported, with followup ranging from 5 months to 2 years. The etiologies of the vasal obstruction included previous inguinal surgery in 7 patients, vasectomy in 1, ejaculatory duct obstruction in 1, ectopic ureter in 1 and vasal agenesis in 1. Factors leading to loss of the contralateral testis were torsion in 5 patients, mumps orchitis in 2, varicocele in 1, pediatric inguinal herniorrhaphy in 1, epididymal blow out in 1 and unknown in 1. A representative case involving a unilateral ectopic ureter emptying into the seminal vesicle and subsequent contralateral testicular torsion is presented. The results indicate that a transseptal crossed vasovasostomy should be done in patients satisfying the criteria presented.

Absence of a vas deferens is a marker for more serious anomalies of the genitourinary tract. It is highly probable that the ipsilateral kidney, ureter or bladder is deformed or absent. The complete physical examination and the preoperative examination for vasectomy should include palpation to identify the vas. The existence of an accessory vas could explain failure of azoospermia following a ligation procedure.

Inverted Y duplication of the ureter is a rare anomaly. We report on a 24-year-old man who presented with urolithiasis and azoospermia in a solitary functioning kidney with an inverted Y ureteral duplication. To our knowledge our case represents the first documentation of ectopic emptying of 1 limb of the inverted Y ureter into the seminal vesicle. The embryology and management of this complex case are discussed.

A case of ectopic vas deferens in a 40-year-old male was reported. He visited our clinic with a complaint of male sterility for the past 10 years. Urological examinations revealed azoospermia, right renal aplasia and the ectopic insertion of right vas deferens into the right lower ureter with a blind-ending ureterocele. Bilateral testicular histological studies showed normal spermatogenesis in right testis and no spermatogenesis in left one. A vasovasostomy was performed. Sperm were seen in the semen 3 weeks after the operation. Including this patient, 54 cases (74 ectopic vas deferens) have been reported in the literature to date. The characteristics of age, subjective complaints, accompanied anomalies, diagnosis, treatment and the embryology are discussed.

A 30-year-old male patient without diabetes mellitus and tuberculosis was referred to our outpatient department for the purpose of further examinations of azoospermia. Transrectal ultrasonography revealed the bilateral calcifications of vas deferens. Kidney-ureter-bladder X-ray and computerized tomography revealed also the same findings. Seminal vesiculography revealed no obstructive sign of vas deferens. Histopathology of testes showed hypoplasia. Judging from these findings, we diagnosed the case as calcification of vas deferens associated with spermatogenic disturbance. Review of the 31 cases reported in the Japanese literature including our case was performed.

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.
