ObjectiveTo investigate the risk factors for the complication of erectile dysfunction after transurethral bipolar plasma enucleation in the treatment of benign prostatic hyperplasia. MethodsA total of 90 patients diagnosed as benign prostatic hyperplasia undergoing transurethral bipolar plasma enucleation were selected. Among them, 9 patients complicated with postoperative erectile dysfunction were included in the dysfunction group, and 81 patients non-complicated with erectile dysfunction were included in the normal group. Univariate and multivariate analyses were performed on the clinical data of the two groups to explore the risk factors for erectile dysfunction in patients with benign prostatic hyperplasia after transurethral bipolar plasma enucleation. ResultsUnivariate analysis results showed that there were no statistically significant differences in BMI, smoking, prostate volume, operation time, bladder irrigation time, and urinary catheter indwelling time between the two groups (all P＞0.05); there were statistically significant differences between the two groups in age, disease course, history of hypertension, history of diabetes, maximum urine flow rate, residual urine volume, intraoperative blood loss, and history of urological surgery (all P＜0.05). Multivariate logistic regression analysis results showed that age ≥65 years old, history of hypertension, history of diabetes, maximum urine flow rate ＜6 mL/s, and history of urological surgery were independent risk factors for the complication of erectile dysfunction after transurethral plasma enucleation in benign prostatic hyperplasia patients (all P＜0.05). ConclusionAttention should be paid to evaluate the presence of risk factors for the complication of postoperative erectile dysfunction in patients with benign prostatic hyperplasia, and predictive intervention should be conducted to decrease the incidence of postoperative erectile dysfunction.
