Objectivization of the Laek of urine during urogynaecological Ultrasound Examination

Overview

Objective:
The objective of our study was to objectify a leak of urine during perineal ultrasoundexamination using a color doppler (CDV), and to compare it with some other ultrasound parameters.Design: A prospective, pilot study.Setting: Department of Gynecology -⁠ Obstetrics of the General Teaching Hospital and the 1stMedical Faculty of the Charles University in Prague, Apolinářská 18, 120 00 Praha 2.Methods: 20 women with stress type of incontinence were included in the study. For all women,we assessed the position and mobility of the bladder neck and we performed an examinationusing a color doppler (CDV). Thereafter, an introital examination followed to detect occurrence offunneling. Subsequently, we performed a perineal examination using an ultrasound contrast me-dium and the CDV, and we compared all examinations performed.Results: During examination without using a contrast medium, a leak of urine was diagnosed byCDV in 14 patients (70% sensitivity), and a funneling in 18 women (90% sensitivity). During exami-nation with a contrast medium, a funneling was present in all 20 patients. In 19 cases, a leak wasdetected using CDV after filling with a contrast substance (95% sensitivity).Conclusion: By a color doppler imaging (CDV) we can objectify a leak of urine, determine theposition of urethra in which such leakage of urine occurs. A contrast medium significantly increases the sensitivity of doppler examination.
