Background: Erectile dysfunction (ED) after a prostate-transurethral resection (P-TUR) is one of the problems in the treatment of benign prostatic hyperplasia (BPH) that may affect the quality of life in middle-aged and older men. The aim of this study was to investigate the impact of P-TUR on ED in BPH patients.
Methods: This study was conducted on 83 patients suffering from BPH that underwent a P-TUR. Clinically, testosterone levels, prostatic-specific antigen (PSA) levels, and prostate volume were measured before the P-TUR. Erectile function was measured prior to the P-TUR, as well as at 1 and 3 months after the P-TUR using the International Index of Erectile Function (IIEF). Suitability test of the model was done in a structural equation. Data were analyzed using the chi-square (χ2,) test by Analysis of Moment Structure (AMOS) software version 21.
Results: The effects of PSA to IIEF before, 1 month after, and 3 months after P-TUR were 0.116, 0.084, and 0.097, respectively. The effects of body mass index to IIEF before, 1 month after, and 3 months after P-TUR were 0.180, 0.066, and 0.164, respectively. The effects of prostate volume to IIEF before, 1 month after, and 3 months after P-TUR were 0.049, 0.004, and 0.011, respectively. The effects of testosterone to IIEF before, 1 month after, and 3 months after P-TUR were –0.029, –0.453, and –0.415, respectively. The effects of age to IIEF before, 1 month after, and 3 months after P-TUR were –0.444, 0.921, and 0.911, respectively.
Conclusion: There was a significant improvement of erectile function in patients that underwent P-TUR who previously had preoperative ED, especially 3 months after the surgery.
