[Influence factors of erectile dysfunction in patients with localized prostate cancer after radical surgery]

To analyze the influential factors of erectile dysfunction (ED) in patients with localized prostate cancer (LPC) after radical surgery.

The clinical data of 150 male patients diagnosed with LPC and normal erectile function (EF) before surgery admitted to the Department of Urology of the Eastern Theatre General Hospital from January 2021 to January 2023 were retrospectively analyzed. The EF status of the patients 6 months after surgery was assessed using the International Erectile Function Index -5(IIEF-5). Age, Gleason score, PSA level, TNM stage, preoperative International prostatic symptom score (IPSS), preoperative prostate volume, smoking index, alcohol consumption index, educational level, comorbidities, operation mode, and psychosexual state were used as influencing factors to analyze their effects on postoperative ED.

Of the 150 patients, 88 had ED and 62 had normal EF. Univariate analysis showed that age, preoperative IPSS, preoperative prostate volume, comorbidities and sexual and psychological status were significantly correlated with postoperative ED. Further multivariate logistic regression analysis showed that age, preoperative prostate volume, comorbidities and sexual and psychological status were independent factors influencing the occurrence of ED after RP in LPC patients.

The recovery of sexual function of patients with localized prostate cancer after radical surgery is generally poor, and the incidence of ED is high. Its independent influencing factors include age, preoperative prostate volume, comorbidities and sexual psychological state, etc. Correct intervention of different influencing factors is required in clinical work. In order to provide a better diagnosis and treatment scheme for LPC patients undergoing radical treatment, reduce the incidence of postoperative ED and improve the quality of life of patients after surgery.
