Abstract

BACKGROUND/PURPOSE:

In this study, we assessed the relationship between changes in intraoperative rectal temperature and erectile function in patients who have undergone transurethral resection of the prostate.

METHODS:

Eighty-six potential patients with benign prostatic hyperplasia-induced lower urinary tract symptoms were studied. Patients were divided into two groups: group 1-small prostates (<40ml) and group 2-large prostates (≥40ml), as determined by transrectal ultrasound measurement. The intraoperative rectal temperature was evaluated using a transrectal thermosensor and the differences between the highest intra- and preoperative temperatures were recorded. The erectile function at baseline, at three months and at one-year postoperatively was assessed using the International Index of Erectile Function-5 (IIEF-5) questionnaire.

RESULTS:

Intraoperative rectal temperature differences were 0.54±0.24°C for group 1 (n=45) and 0.44±0.20°C for group 2 (n=41), (p=0.04). The IIEF-5 scores for group1 and group 2 were, respectively, 20.9±1.6 and 20.6±1.6 at baseline (p=0.32), 17.3±2.9 and 18.7±3.2 (p=0.037) at 3 months, 17.9±2.7 and 18.7±3.0 (p=0.17) at 1 year postoperatively. The deterioration of erectile function at 3 months post-operatively was observed for both groups. The percentage of retrograde ejaculation between two groups was not significantly different (p=0.33) at 1 year postoperatively.

CONCLUSION:

Our study revealed that a higher intraoperative rectal temperature difference caused by transurethral resection of the prostate might affect the postoperative erectile function, particularly in patients with a small prostate.
