To evaluate the long-term efficacy of electrofulguration in women with recurrent urinary tract infections.
After institutional review board approval, a retrospective study of women who underwent electrofulguration alone was carried out. All patients had recurrent urinary tract infections defined as three or more urinary tract infections/year, and a preoperative office cystoscopy showing inflammatory lesions, categorized by location: urethra, bladder neck, trigone and beyond the trigone. All lesions were cauterized during outpatient electrofulguration under anesthesia. On 6-month postoperative office cystoscopy, endoscopic success was defined as resolution of all lesions previously seen and no new lesions. The primary outcome was urinary tract infections/year, with urinary tract infection defined as antibiotic treatment for urinary tract infection-like symptoms and/or for positive urine culture. Clinical cure was defined as no further urinary tract infections, clinical improvement as less than three urinary tract infections/year, and clinical failure as three or more urinary tract infections/year.
Of 95 women who met the study criteria between 2004 and 2016, 62 (65%) were endoscopically successful, and 33 (35%) were endoscopic failures based on postoperative cystoscopy. Among all patients, over a median follow-up period of 4.9 years, the median number of urinary tract infections/year was 0.8. Endoscopically successful patients had fewer urinary tract infections/year compared with endoscopic failures (0.6 vs 0.9, P = 0.03). Clinically, 14 (15%) patients were cured, 69 (73%) were improved and 12 (13%) failed. Compared with clinically improved patients, clinical failures were more likely to have infections with multiple organisms (92% vs 35%, P < 0.001) and highly resistant organisms (92% vs 23%, P < 0.001).
In our experience, nearly two-thirds of women with recurrent urinary tract infection can be successfully treated with electrofulguration, and >80% experience long-term clinical cure or improvement in urinary tract infections.
评估电灼术治疗复发性尿路感染的长期疗效。
本研究经机构审查委员会批准,对单独接受电灼术治疗的女性患者进行了回顾性研究。所有患者均患有复发性尿路感染,定义为每年发生 3 次或以上尿路感染,术前门诊膀胱镜检查显示炎症病变,按部位分类:尿道、膀胱颈部、三角区和三角区以外。所有病变均在全身麻醉下门诊电灼时烧灼。术后 6 个月门诊膀胱镜检查时,内镜成功定义为先前所见所有病变消退且无新发病变。主要结局为每年尿路感染次数,尿路感染定义为尿路感染样症状抗生素治疗和/或尿液培养阳性。临床治愈定义为无进一步尿路感染,临床改善定义为每年尿路感染次数少于 3 次,临床失败定义为每年尿路感染次数为 3 次或以上。
在 2004 年至 2016 年间符合研究标准的 95 名女性中,62 名(65%)内镜成功,33 名(35%)内镜失败。所有患者中位随访时间为 4.9 年,中位每年尿路感染次数为 0.8 次。与内镜失败患者相比,内镜成功患者每年尿路感染次数更少(0.6 次比 0.9 次,P=0.03)。临床方面,14 名(15%)患者治愈,69 名(73%)患者改善,12 名(13%)患者失败。与临床改善患者相比,临床失败患者更有可能感染多种病原体(92%比 35%,P<0.001)和高度耐药病原体(92%比 23%,P<0.001)。
根据我们的经验,近三分之二的复发性尿路感染女性可以通过电灼术成功治疗,超过 80%的患者在尿路感染方面具有长期临床治愈或改善。
