Are there adverse effects of herniorrhaphy techniques on testicular perfusion? Evaluation by color Doppler ultrasonography.
OBJECTIVE
To evaluate the efficacy of prosthetic meshes on testicular perfusion using color Doppler ultrasound (CDUS).


METHODS
This study is a randomized prospective clinical trial with blind assessment of outcome. A total of 26 patients who underwent elective herniorrhaphy for groin hernia participated in the study. Each patient was randomly assigned to 1 of 2 groups: totally extraperitoneal preperitoneal hernia repair (TEP; n=13, mean age 46.7+/-1.6 years) or Lichtenstein hernia repair (LHR; n=13, mean age 54.2+/-2.7 years). Six of the patients had bilateral hernias (n=3 for each group). Blood flow indexes of the spermatic artery including end diastolic velocity (EDV), peak systolic velocity (PSV) and the resistive index (RI) were examined by CDUS. Ultrasound was performed just before the operations and repeated after 3 months. Kruskal-Wallis and Mann-Whitney U tests were used to evaluate the differences.


RESULTS
No statistically significant differences were found between the preoperative and postoperative measurements which included blood flow parameters (PSV, EDV, and RI) of the testes (p>0.05).


CONCLUSIONS
Neither the TEP or LHR technique had any decreasing effect on blood flow.
