The validity of methods for determining urethral length and the precise location of the mid\u2010urethral complex for SUI treatment have been sparsely studied. The aim of this study was to investigate the agreement between urethral lengths measured with a catheter and by transperineal ultrasound.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Fifty\u2010seven women with SUI or mixed urinary incontinence (MUI) with predominant stress symptoms were recruited. The urethral length was assessed with 3D transperineal ultrasound and measurements were taken offline from the postero\u2010inferior margin of the pubic symphysis to the bladder neck. Then, it was measured with a foley catheter by another evaluator, blinded to the ultrasound data. The distance between the inflated balloon and the urethral meatus was considered.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Thirty\u2010three women (58%) had SUI and 24 (42%) had MUI. The mean urethral length evaluated with ultrasound and the catheter were 3.03\u2009\u00b1\u20090.34\u2009cm and 3.02\u2009\u00b1\u20090.41\u2009cm (<jats:italic>P<\/jats:italic>\u2009=\u20090.857), respectively. Agreement between the two methods as assessed by the intra\u2010class correlation coefficient was 0.90 (CI0.82\u20100.94, <jats:italic>P<\/jats:italic>\u2009\u2264\u20090.001). Limits of agreement (Bland\u2010Altman) were +0.46 to \u22120.45\u2009cm, with a mean difference of \u22120.01\u2009\u00b1\u20090.23\u2009cm.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Findings of this study, reveal an excellent agreement between a simple catheter technique and ultrasound assessment for measuring urethral length, with a small mean bias and clinically acceptable limits of agreement. This provides relevant information in clinical practice for determining optimal placement of periurethral material or mid\u2010urethral tape for SUI treatment.<\/jats:p><\/jats:sec>","DOI":"10.1002\/nau.23805","type":"journal-article","created":{"date-parts":[[2018,9,4]],"date-time":"2018-09-04T06:43:32Z","timestamp":1536043412000},"page":"2875-2880","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Agreement
