Brief summary
Between 5 and 8% of men having had a vasectomy wish a vasectomy reversal. Vasectomy reversal, also called vaso-vasostomy or vaso-epididymostomy, depending on the technique, is used to be in general or neuraxial anesthesia. Performing ultrasound-guided spermatic cord block avoids the potential risks of first general and neuraxial anesthesia and second vascular damage by the injection of the block. Moreover, it provides long-lasting postoperative analgesia. The aim of this study was to evaluate the feasibility of the ultrasound-guided spermatic cord block in patients scheduled for vasectomy reversal and to compare the results with a corresponding retrospective series in general or neuraxial anesthesia.
Interventions
Patients scheduled for vasectomy reversal are prospectively included into the study. Vasectomy reversal is done in regional anesthesia with an ultrasound-guided spermatic cord block instead of general or neuraxial anesthesia. The ultrasound-guidance is done under sterile conditions 15 minutes before surgery on each side at the inguinoscrotal level by injection of 5ml short- and 5ml long-acting local anesthesia. Before, during and after the operation pain-level by visual-analogue-scale (VAS) and
Patients scheduled for vasectomy reversal are prospectively included into the study. Vasectomy reversal is done in regional anesthesia with an ultrasound-guided spermatic cord block instead of general or neuraxial anesthesia. The ultrasound-guidance is done under sterile conditions 15 minutes before surgery on each side at the inguinoscrotal level by injection of 5ml short- and 5ml long-acting local anesthesia. Before, during and after the operation pain-level by visual-analogue-scale (VAS) and general anesthesiological values are monitored on a regular base. Postoperatively, monitoring of first request of an analgetic treatment, first alimentation, first mobilization and discharge is noted until discharge of the patient, which usually takes place within 24 hours. Analysis of complications until 7 days postoperatively. End of monitoring 7 days postoperatively.
