To determine cohort urethral length, identify epidemiological factors influencing the parameter and to establish the percentage of cases with clinically relevant outsized urethras.
Prospective cohort study conducted in two tertiary clinical centers between 2013 and 2017. Nine hundred and twenty seven consecutive adult, Caucasian females attending outpatients' clinics were included. The urethral length has been measured in pelvic floor ultrasound examination. The exclusion criteria were inadequate bladder filling (<200 mL; >400 mL), previous history of pelvic floor surgery, and no consent.
Urethral length varied from 19 to 45 mm. The distribution of the examined parameter was normal. Obese patients had significantly longer urethras as compared to non-obese subjects. Number of vaginal deliveries was connected with shorter urethral length. The limitations of the study are: analysis only of Caucasian patients and subjects without previous pelvic floor surgeries.
Differences in urethral length in the female population were demonstrated. Thirty percent of patients have atypical urethras that may be a risk factor for sling surgery failure. We therefore postulate introduction of urethral measurement before the procedure.
确定队列尿道长度，确定影响该参数的流行病学因素，并确定具有临床相关过大尿道的病例百分比。
2013 年至 2017 年在两个三级临床中心进行的前瞻性队列研究。纳入 927 例连续成年白人女性门诊患者。在盆底超声检查中测量尿道长度。排除标准为膀胱充盈不足（<200 毫升；>400 毫升）、既往盆底手术史和不同意。
尿道长度从 19 毫米到 45 毫米不等。所检查参数的分布呈正态分布。肥胖患者的尿道明显长于非肥胖患者。阴道分娩次数与尿道长度较短有关。本研究的局限性在于：仅分析白种人患者和无既往盆底手术史的患者。
证明了女性人群中尿道长度的差异。30%的患者存在非典型尿道，这可能是吊带手术失败的危险因素。因此，我们假设在手术前进行尿道测量。
