MR 34. Analysis of patency rates of microsurgical intussuception vasoepididymostomy for patients with obstructive azoospermia (analysis of 19 cases)

Objective: To analysis the clinical patency rates of microsurgical intussuception vasoepididymostomy for patients with obstructive azoospermia.

Methods: we retrospectively analyzed data and surgical procedure from 19 patients with obstructive azoospermia between 2008 and 2011. The data included medical record, physical examination, sperm analysis (twice at lest and once after centrifugation, including volum, PH, liquefaction of seminal plasma), seminal plasma biochemistry group item (fructose, neutral alpha-glucosidase, elastase), scrotal and transanal ultrasound, serum reproductive hormones,testicular biopsy. The clinical data predicated the causes and sites of obstruction. Treatment were based on the data.

Results: There were a total of 19 cases undergoing microsurgical intussuception vasoepididymostomy The mean follow-up was 9.3±4.3 months (range 3-19). The overall patency rate was 78%. The patency rate was 94% (n=16), 0% (n=3) for single obstruction and epididymal fullness on each side, multiple obstruction on each side, respectively.

Conclusions: Intussusception vasoepididymostomy can provide a good patency rate for patients with single obstruction and epididymal fullness on each side, but multiple obstruction on each side isn't suitable for vasopididymostomy.
