A Randomized-Controlled, Prospective Study on the Effect of Dorsal
Penile Nerve Block after TURP on Catheter-Related Bladder Discomfort and
Pain
Abstract
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.
