A pilot study of transperineal urethrosphincteric block for visual internal urethrotomy in patients with anterior urethral strictures.
OBJECTIVE
To evaluate the effectiveness of transperineal urethrosphincteric block (TUSB) in providing analgesia during visual internal urethrotomy for patients with anterior urethral strictures.


METHODS
A total of 26 consecutive patients scheduled for elective visual internal urethrotomy for symptomatic urethral stricture were considered for this prospective study. Twenty-four patients agreed to participate in the study. Their demographics and medical conditions were recorded. Twenty-five percent of the patients had comorbid conditions that would have put them at high risk for general anesthesia. All patients had TUSB as the primary method of analgesia, using 1% lidocaine. Postoperatively, patients were asked to score the severity of the pain experienced during TUSB and during the transurethral surgery on a scale from 0 to 10. Postoperative adverse effects and the need for sedation or additional analgesia were recorded. All patients rated their overall satisfaction with the analgesia.


RESULTS
Patient mean age was 43.5 years (range 26-71 years). The mean pain score during instillation of the transperineal block was 1.9 (range 0-3), and for visual internal urethrotomy was 1 (range 0-5). No sedation, narcotics, or additional analgesia were required and no postoperative adverse effects were encountered. Ninety-two percent of the patients were very satisfied with the method of analgesia.


CONCLUSIONS
TUSB is a safe and effective method of local analgesia for visual internal urethrotomy in patients with anterior urethral strictures, and is particularly suitable for those at high risk of general anesthesia.
