[Modified technique for transurethral resection of the prostate with suprapubic drainage and local anesthesia].

PURPOSE: To establish a technique for transurethral resection of the prostate (TURP), combining the use of local anaesthesia with an Amplatz suprapubic tube, in patients at high surgical risk.

MATERIALS AND METHOD: A study was carried out in 32 patients who underwent TURP with a 30 F Amplatz suprapubic tube following local anaesthesia. This technique was indicated where surgery presented a general risk, in elderly patients, and for patients refusing to undergo spinal intradural or general anaesthesia. The mean age of the patients was 70 years (61-82 years). The risk of surgery was assessed according to the ASA classification.

RESULTS

According to the ASA classification, 7 patients were ASA III (21.9%), and 25 patients were ASA IV (78.1%). In 31 of the 32 patients the operation was completed in one session. When questioned about the pain they felt, 11 patients reported no pain, 12 slight discomfort and 3 occasional pain. In the latter three patients, intravenous sedation was enhanced with 0.1 mg etomidate per kg body weight. The volume of the resected fragments ranged from 18 to 120 ml, with a mean of 47 ml, except in one patient with 205 ml who required two treatment sessions.

CONCLUSIONS

Large prostate resection in patients at high surgical risk was performed comfortably using a combination of local anaesthesia and an Amplatz suprapubic tube. This procedure is one possible option to be considered as an alternative to other treatments.
