目的:探讨经尿道等离子前列腺剜除术（TUERP）术后急性附睾-睾丸炎的危险因素。方法:回顾性分析大连医科大学附属第二医院2015年6月至2018年9月710例良性前列腺增生患者的临床资料。其中，行TUERP治疗220例，行经尿道前列腺切除术（TURP）治疗490例。比较两种术式患者术后急性附睾-睾丸炎发生情况，分析影响TUERP患者术后急性附睾-睾丸炎的危险因素。结果:TUERP患者术后附睾-睾丸炎发生率明显高于TURP患者[9.55%（21/220）比4.08%（20/490）]，差异有统计学意义（n χ2 = 8.33，n P3 d、术前尿白细胞阳性、前列腺体积>80 ml和手术时间>90 min是TUERP患者术后发生急性附睾-睾丸炎的危险因素（n P3 d是影响TUERP患者术后发生急性附睾-睾丸炎的独立危险因素（n OR = 12.402和3.642，95% n CI 4.581~33.579和1.218~11.204，n P3 d是TUERP患者术后急性附睾-睾丸炎的独立危险因素。“,”Objective:To explore the risk factors of acute epididymo-orchitis after transurethral plasma enucleation and resection of prostate (TUERP).Methods:The clinical data of 710 patients with benign prostatic hyperplasia (BPH) from June 2015 to September 2018 in the Second Hospital of Dalian Medical University were retrospectively analyzed. Among them, 220 cases were treated with TUERP and 490 cases were treated with transurethral resection of prostate (TURP). The incidence of postoperative acute epididymo-orchitis was compared between 2 groups and the risk factors of acute epididymo-orchitis were analyzed.Results:The incidence of epididymo-orchitis in TUERP patients was significantly higher than that in TURP patients: 9.55% (21/220) vs. 4.08% (20/490), and there was statistical difference (n χ2 = 8.33, n P 3 d, preoperative leukocyte positive, prostate volume > 80 ml and operation time > 90 min were the risk factors of acute epididymo-orchitis after TUERP (n P 3 d were the independent risk factors of acute epididymo-orchitis after TUERP (n OR = 12.402 and 3.642, 95% n CI 4.581 to 33.579 and 1.218 to 11.204, n P 3 d are independent risk factors of acute epididymo-orchitis after TUERP.
