Resumo: ABSTRACT Introduction: When the vasectomy reversal (VR) fails, and the patient desires natural conception with his sperm, vasectomy re-reversal (VRR) is the only alternative. Purpose: To determine the VRR effectiveness and whether specific parameters can be associated with its success. Materials and Methods: We retrospectively evaluated 18 consecutive vasectomized patients, who had failed their VR through bilateral vasovasostomy, and posteriorly were submitted to VRR. The parameters of the study were: age of the patients, elapsed time between vasectomy and VRR (V-VRRt), elapsed time between VR and VRR (VR-VRRt), presence of spermatozoa in the proximal vas deferens fluid (SptzVDF) in the VRR and results of semen analysis after VRR (SA-VRR). Results: The mean of the age of the patients was 44.11±6.55 years (32.0-57.0), the mean of V-VRRt was 11.76±6.46 years (1.5-25.0) and the mean of VR-VRRt was 2.13±2.27 years (0.5-10.0). SptzVDF in the VRR were found bilaterally in 8 patients, unilaterally in 4 and absent in 6. SA-VRR demonstrated normozoospermia in 9 patients, oligozoospermia in 3 and azoospermia in 6, with patency rate of 66.67%. SA-VRR showed statistically significant dependence only with SptzVDF in the VRR (p <0.01). Conclusions: VRR was effective in restoring the obstruction in more than half of the patients. Furthermore, the presence of spermatozoa in the vas deferens fluid was the parameter associated with the VRR success.
