Objective: To evaluate the lidocaine gel's application effect versus the periprostatic placement of lidocaine to manage the pain in patients who go through a prostate biopsy. Materials and Method: We took the patients who entered the FCI-IC to effectuate a prostate biopsy with an echographic guideline. The patients were split in two groups of 22 people with each one bearing similar characteristics. One of these groups experimented the previous prostate biopsy with 10cc of intrarectal lidocaine gel and the other group experimented 10 cc of lidocaine to 1% in the vesic-prostatic through echographic guidelines. To evaluate the pain, we used the visual analogue scale to gauge the pain during and after the procedure in both groups. The daily procedure to do biopsies by octants and their subsequent preparation remained the same and never changed. Results: The average scale of pain during the procedure was 2.0 for the group with injected anaesthesia and 4.77 for the group who used gel. After the procedure the average of pain was 0.77 and 3.14 respectively. Some complications as bacteremy were present in 3 patients (6.8%) of the total, who were in the gel group and none were found in the group of injected anestesia. No significant relation was found with respect to other variables. Conclusions: the application of periprostatic lidocaine is efficient to control the pain in patients who go through a prostate biopsy. Besides, it is a safe procedure which can be easily reproduce in our environment.
