[Comparison of 3 microsurgical approaches to the treatment of varicocele: report of 120 cases].
OBJECTIVE
To compare the outcomes of the three microsurgical strategies, inguinal high ligation (IHL), retroperitoneal high ligation (RHL) and low ligation (LL) of internal spermatic veins, in the treatment of varicocele.


METHODS
We retrospectively analyzed 120 cases of varicocele, which were equally divided into groups I , II and III to be treated by IHL, RHL and LL of internal spermatic veins, respectively. We compared the operation times, post-operative complications, recurrence rates and results of pre- and post-operation semen analysis among the three groups.


RESULTS
The mean operation time was significantly longer in group III ( [55 +/- 6 ] min) than in I ([35 +/- 10] min) and II ([42 +/- 12] min) (P<0.05), while the rate of post-operative complications remarkably higher in group I (4 cases of hydrocele [10% ] and 3 cases of epididymitis [7.5%]) than in II (2 cases of hydrocele [5%] and 2 cases of epididymitis [5%]) and III (1 case of hydrocele [2.5%] and 1 case of epididymitis [2.5%]) (P<0.05). Six to 12 (mean 9) months of follow-up visit found 2 cases (5% ) of recurrence in group I, 1 case (2.5%) in group II and none in group III, with no statistically significant difference among the three groups (P>0.05). At 12 months after surgery, group III showed significantly higher sperm concentration, grade a +b sperm and the sperm motility than the other two (P<0.05), but no significant differences were observed in these parameters among the three groups preoperatively.


CONCLUSIONS
As a microsurgical approach to the treatment of varicocele, LL is better than IHL and RHL of internal spermatic veins in improving the seminal parameters of the patients.
