OBJECTIVE: To evaluate the effect of the rectal administration of lidocaine gel on the tolerance of systematic sextant transrectal ultrasonography (TRUS)-guided prostatic biopsies. PATIENTS AND METHODS: From January to September 1997, patients undergoing initial biopsy mapping of the prostate (with six systematic TRUS-guided transrectal biopsies) were randomized using a pre-established randomization list into two groups. In group 1, 15 mL of 2% lidocaine gel (Astra, Södertälje, Sweden) was administered intrarectally 15 min before the biopsies. In group 2 (placebo), 15 mL of trans-sonic hydrophilic gel (Rivadis Laboratory, Thouars, France) was administered transrectally under the same conditions. Patients were randomized and the gel administered by a nurse; neither the patients nor the urologists were aware of which product was administered. At the end of the procedure, patients were asked to score the severity of discomfort of the biopsies, using a self-administered rating scale. RESULTS: In all, 109 patients were included, in either group 1 (56 patients) or group 2 (53 patients). Slight pain or no pain was experienced by the vast majority of patients in both groups. Moderate to severe pain was experienced in 12.5% of patients in group 1 and 11.3% of patients in group 2. There was no difference in patient tolerance between the groups (P=0.39). Only minor complications occurred and complication rates were not significantly different between the groups. CONCLUSION: The rectal administration of lidocaine has no impact on the tolerance to prostatic biopsy.
