Abstract
A total of 522 patients out of the 584 vasovasostorny
patients were followed-up during the
past IS years. Better results were obtained III
shorter duration of obstruction, bilateral straight
vas-to-straight vas anastomosis, bilateral leakages
of spermatic fluids groups. Results of endto-
end technique were similar to side-to-side
technique in macrosurgery but those of twolayer
technique were superior to full-thickness
technique in microsurgery. Success rates were
84% for patency and 35% for pregnancy in
the 300 macrosurgeries and 90% for patency
and 46% for pregnancy in the 222 microsurgeries.
Failure of patency was mainly due to
the scar formation with sperm and suture
granulomas.
A total of 155 patients out of the 174 epididymovasostomy
patients for post-inflammatory
epididymal obstruction were followed-up during
the past 18 years. Success rates were found to be
higher in patients with non-tuberculous epididymitis
than tuberculous epididymitis. There were
no significant differences among the anastomosis
levels of epididymal window. Success rates were
31?0 for patency, 12% for pregnancy in the 97
macrosurgeries and 36% for patency and 21?6
for pregnancy in the 58 microsurgeries. Causes
of anatomical failures were scar formation at
the anastomosed site and blockage of opening
of the original epididymal tubule.
