Influence of transurethral resection on sexual dysfunction in patients with prostate cancer.
OBJECTIVE
To evaluate retrospectively the potential influence of disease-related factors and transurethral resection of the prostate (TURP) on the sexual function of patients who had undergone curative radiotherapy for prostate cancer.


METHODS
The study comprised 104 patients (median age 69.5 years, range 49-81) who had been treated with curative radiotherapy and no first-line hormones: 16, 52, 33 and three patients had T1, T2, T3 and T4 tumours, respectively. TURP was performed in 73 patients before RT, and needle biopsy alone in 31 patients. They were interviewed about their past and present sexual lives using a questionnaire designed to evaluate the potency of the patients at age 45 years, at 1 year before the diagnosis of the disease, before radiotherapy (after TURP or needle biopsy) and at the last follow-up. Information concerning associated diseases, routine medication and the weight of the resected material was also collected.


RESULTS
Before diagnosis, 20 patients had no erections while 84 were potent. Of the 60 potent patients undergoing a TURP, 31 (51%) indicated complete impotence immediately thereafter. There was no statistical difference between impotent and potent patients after TURP in age, associated diseases, medical treatment and the weight of the resected material.


CONCLUSIONS
TURP may lead to impotence in a significant proportion of patients. As TURP is an important component of "conservative' treatment approaches, its potential sexual morbidity should be taken into consideration in the comparative risk-benefit analysis of different therapeutic strategies.
