Analysis of risk factors for epididymitis after transurethral resection of prostate

Objective To investigate the risk factors associated with epididymitis after transurethral resection of prostate. Methods A retrospective analysis of 352 patients with benign prostatic hyperplasia (BPH) who underwent transurethral resection of prostate in X′an Aerospace General Hospital from January 2015 to December 2017 was performed. There were 14 cases of epididymitis and 338 cases of non-epididymitis. Measurement data were expressed as (±s), t test was used for comparison between groups; count data was expressed by rate (%), and chi-square test was used for comparison between groups. Univariate and multivariate logistic regression analyses were used for factors that may lead to post-urethral epididymitis. Results Univariate logistic regression analysis showed that preoperative leukocytic positive, urine glucose positive and prostate volume had significant effects on postoperative epididymitis (P<0.05). Multivariate logistic regression analysis showed that prostate volume increased (OR=0.182, P=0.005) was an independent risk factor for postoperative epididymitis. Conclusion The enlargement of prostate volume is an independent risk factor for postoperative epididymitis. For large-volume prostate surgery, the purpose of relieving obstruction can be achieved.
