In the situations that intracytoplasmic sperm injection (ICSI) hts revolutionized the
treatment of male infertility, there appeared some needs to evaluate the role of
microsurgical single tubular epididymovasostomy (EV). The outcome of microsurgical
single tubular EV for obstructive azoospermia patients was retrospectively reviewed in
61 patients who had been followed for more than 18 months postoperatively. The overall
patency rate followed surgery was 69% (42/61 patients), and live-birth rate was 31%
(19/61 patients). Of these 19 men 13 were able to impregnate their partners; 6 of the 19
live-birth were achieved with the assisstance of conventional IVF. Previously known
prognostic factors-etiology, preoperative testis biopsy findings and intraoperative
presence of sperm or motile sperm- all did not affect the patency and pregnancy rate.
The live-birth rate of ICSI has been reported about 20¡40%. Our results suggest that
microsurgical single tubular EV is the preferential method to treat obstructive
azoospermia patients concerning the merits of natural pregnancy and high patency rate.
ICSI would be applied to the patients with patent anastomoses who have failed to
achieve natural pregnancy. We think that microsurgical single tubular EV in obstructive
azoospermaia patients should be performed more actively by well-trained urologists in
more expanded indications.
