PurposeThis study aimed to examine the effect of postoperative addition of a local anesthetic agent to irrigation fluid on the alleviation or prevention of pain after transurethral resection of the prostate (TURP).Patients And MethodsThis prospective, double blind, placebo-controlled study included 50 patients aged 50 to 87 years. The patients were randomized into two groups. As each patient began to experience postoperative pain after spinal anesthesia wore off, 30 mL of 2% prilocaine was injected into the irrigation solution bags, and the bladder was irrigated (prilocaine group). The irrigation solution used in the control group was prilocaine-free. Visual analog scale (VAS) scoring was used to assess the severity of pain. Bladder irrigation in all patients was discontinued 1 day postsurgery.ResultsThere was not a statistical difference in surgical parameters between the two groups. All patients in the prilocaine group were satisfied with the analgesic efficacy of prilocaine, except for two (8%). The mean number of irrigation solution bags (3000 mL) used for each patient in the prilocaine group was 7.04 ± 1.2. Prilocaine-related side effects were not observed. Conversely, pain developed in all but two patients in the control group. The mean number of irrigation solution bags used for each patient in the control group was 7.6 ± 1.8. Mean VAS pain score was 0.35 ± 0.12 and 5.10 ± 3.26 in the prilocaine and control groups, respectively (P<0.001).ConclusionPrilocaine solution safely alleviated postoperative pain in the patients who underwent TURP. The use of continuous bladder irrigation with a diluted prilocaine solution consistently decreased the need for parenteral analgesics.
