Introduction: We have developed a modified vasoepididymostomy procedure, namely "fenestrated" transversal two-suture microsurgical intussusception vasoepididymostomy. This study aimed to investigate the therapeutic efficacy and outcome of this fenestrated vasoepididymostomy for epididymal obstructive azoospermia. Methods: Microsurgical two-suture transversal intussusception vasoepididymostomy was performed using our modified fenestration technique in 64 obstructive azoospermia (OA) patients due to epididymal obstruction at our hospital. Fenestration means making an opening on the epididymal tubule wall. The edges of the epididymal tubule "window" were stitched transversally (2 stitches) using the two double-armed 9-0 atraumatic suture. The epididymal tubule was anastomosed to the lumen of the vas deferens. The patency rate and pregnancy rate were assessed. Results: Of the 64 OA patients, 45 received bilateral microsurgical two-suture transversal intussusception vasoepididymostomy while 19 underwent unilateral microsurgical two-suture transversal intussusception vasoepididymostomy. All of the patients were followed up after the operation. The follow-up period ranged from 4 to 54 months. Among 45 cases of bilateral surgery, the patency rate was 88.89% (40/45), and the natural pregnancy rate was 28.89% (13/45). After the patency was confirmed postoperatively, 3 cases had recurrent OA, of which 2 cases had return of sperm to the ejaculate by oral antibiotics and scrotal self-massage. As for the 19 cases of unilateral microsurgery, the patency rate was 68.42% (13/19), and the natural pregnancy rate was 21.05% (4/19). Conclusion: The fenestrated transversal two-suture microsurgical intussusception vasoepididymostomy can achieve a good patency rate in OA patients, and did not increase the difficulty and duration of the procedure.
