Erectile dysfunction following transurethral resection of the prostate

Area of Science:

• Urology
• Andrology
• Men's Health

Background:

• Transurethral resection of the prostate (TURP) is a common surgical procedure for benign prostatic hyperplasia.
• Concerns exist regarding potential sexual side effects, including erectile dysfunction (ED).
• Previous studies often relied on subjective patient reports, which may be influenced by factors other than true erectile function.

Purpose of the Study:

• To objectively assess the incidence of erectile dysfunction following TURP.
• To compare objective measures of erectile function before and after the surgical procedure.
• To investigate the impact of subjective patient reporting on perceived sexual outcomes after TURP.

Main Methods:

• A cohort of 56 men undergoing TURP were enrolled.
• Nocturnal penile tumescence (NPT) testing was performed for 3 nights preoperatively and 3 months postoperatively.
• Patients also completed questionnaires on perceived sexual dysfunction.

Main Results:

• Complete data were analyzed for 40 patients.
• No significant differences were observed in penile tumescence, number, or duration of erectile events.
• A slight, statistically significant improvement in penile rigidity was noted post-TURP (p < 0.05).
• 27.5% of patients reported a subjective decrease in erection quality; however, 63.6% of these attributed it to retrograde ejaculation, not impaired erectile function.

Conclusions:

• Objective measures demonstrate no decline in erectile function after TURP.
• Subjective patient reports of impotence following TURP may be overestimated due to confusion with retrograde ejaculation.
• This study highlights the importance of objective assessment in evaluating sexual function after prostate surgery.
