[Impact of transurethral resection of the prostate on erectile function: a report of 64 cases].

OBJECTIVE
To analyze the impact of transurethral resection of the prostate (TURP) on erectile function and the factors influencing postoperative erectile function.


METHODS
Altogether 64 male patients aged 53 -75 (mean 66.5) years underwent TURP for prostatic hyperplasia. Before and 3 months after surgery, we observed the nocturnal penile tumescence of the patients and analyzed their scores on the 5-item version of the International Index of Erectile Function (IIEF-5) and the Self-Rating Anxiety Scale (SAS).


RESULTS
Intraoperative prostatic capsule perforation and postoperative stress were significantly related to postoperative erectile dysfunction (P < 0.05). The mean score of IIEF-5 was significantly decreased (P < 0.01) while that of SAS remarkably increased (P < 0.01) after TURP as compared with those before surgery. The frequency of nocturnal penile tumescence was reduced at 3 months after surgery, but with no statistically significant difference.


CONCLUSION
Intraoperative prostatic capsule perforation and postoperative stress obviously affect postoperative erectile function.
