Purpose:In the present study, the impact of penile nerve block(PNB) on postoperative pain and CRBD in transurethral resection of prostate(TURP) patients were evaluated. Methods:Participants of the present study were selected from patients who performed TURP under spinal anesthesia for benign prostatic hyperplasia(BPH) between January 2018-July 2020. This study was planned as a single center, randomized-controlled prospective study. The patients were divided into two groups; Group 1 was administered Control(n:40), and Group 2 ultrasonography(USG) guided PNB(n:40). The patients were included in the Groups respectively. Visual analogue scale(VAS) scores were questioned and recorded in order to evaluate the postoperative pain complaints of the patients after the operation. In addition, in order to evaluate the CRBD, VAS scores were questioned and recorded as 0-1th hour, 1st-2nd hours, 2nd – 4th hours, 4th-8th hours, 8th-12th hours, and 12th-24th hours. In addition, postoperative pain and analgesic need were recorded. Tramodol was given to patients with moderate to severe CRBD. The findings was compared between to the Groups. Results:There was no statistical difference between Group 1 and Group 2 between demographic and per-operative data. The CRBD and pain-related VAS scores was significantly higher in Group 1 between the 0-8th hours. There was no difference between VAS scores in the postoperative 8-24th hours. In total 24 hours, Group 2’s need for tramodol for CRBD and pain was significantly less than Group 1. On examining the factors affecting CRBD in the multivariate analysis, age, body mass index(BMI), prostate volume, operation time do not affect CRBD statistically, only PNB reduces CRBD (p: 0.029). While less drug-related complications were observed in Group 2, no serious complications related to PNB were observed. Conclusion:PNB is the effective method for the decrease pain and CRBD after urological surgery.It will also reduce the need for analgesics, and provide the painless patients in postoperative period.
