Single incision transumbilical laparoscopic varicocelectomy versus the conventional laparoscopic technique: A randomized clinical study.
BACKGROUND
Varicocele is the most common correctable cause of infertility. We analyzed the outcomes of single incision laparoscopic varicocelectomy (SIL-V) in comparison with conventional transperitoneal varicocelectomy (CTL-V).


METHODS
Patients with clinically palpable varicocele treated by laparoscopic varicocelectomy were randomly allocated into two groups: SIL-V and CTL-V group. The primary outcome measures were improvement in semen parameters and resolution of testicular pain. Secondary outcome measures included operating time, postoperative pain scores, time to return to normal activity, patient satisfaction and postoperative complications.


RESULTS
Eighty patients completed the study. No vascular or intestinal complications occurred during both procedures. All patients were discharged 24 h postoperatively. The parameters measuring the success of varicocelectomy had improved for the majority of patients with no significant difference between the two groups. There was significantly longer operating time in SIL-V group (44.6 ± 5.4 min) than in CTL-V group (41.3 ± 8.5 min) (P = 0.03). The difference in operating time was lost when bilateral procedures were compared (P = 0.21). The mean VAS scores for pain at 3, 24 and 48 h postoperatively were significantly lower in SIL-V group (P = 0.02, P = 0.03 and P < 0.001 respectively). Time to return to normal activity was significantly shorter in SIL-V (P < 0.001). Patient satisfaction was significantly higher in SIL-V group (P < 0.01). Postoperative complications were comparable in both groups.


CONCLUSIONS
SIL-V is a safe and effective straightforward alternative to the well-established and accepted CTL-V. The tendency toward decreased postoperative pain, rapid return to normal activity and the high patients' satisfaction rate regarding cosmetic results are potential benefits of SIL-V procedure.
