Effect of Bladder Filling on Changes in UltrasoundParameters of the Lower Urinary Tract in Women withStress Incontinence

Overview

Objective of the Study:
was to evaluate the effect of filling the bladder on position and mobility ofUV junction, and to determine other possible changes of measured ultrasound parameters of thelower urinary tract in relation to filling of the bladder.Type of Study: prospective randomized clinical studyName and Address of the Workplace: Department of Gynaecology -⁠ Obstetrics, 1 st Faculty ofMedicine of Charles University and VFN in PragueMethodology: 20 women were included in our study with proved stress incontinence of urine(—GSIii). Their average age was 46 years, average weight 70 kg, average parity 1.57. Perineal andintroital ultrasound examination was performed in a supine position, using Acuson 128 XP 10equipment, a convex probe of 5 MHz frequency and a vaginal probe of 7.0 MHz.Position and mobility of UVJ was monitored based on the following parameters: angle g g, abscissasp, h, x, y. Bladder filling was 300 ml, 200 ml and empty bladder.Results: Statistically significant differences were observed in UVJ mobility during contractions ofpelvic floor muscles between measurements, when the bladder contained 300 ml of liquid, or wasempty (p = 0.00983). UV-junction of and empty bladder is higher during a contraction, and themobility is greater (p = 0.006). Distances x, y, p in case of an empty bladder are shorter duringcontraction and the g g angle is smaller (p = 0.01). The thickness of the bladder wall was greater inan empty bladder (p = 0.01). Changes in area and thickness of the urethral sphincter were notsignificant.Conclusion: Based on our preliminary results we can state that a bladder filling of 300 ml is notsignificant for evaluation of UV-junction mobility. Rather the opposite; a higher mobility of UV-junction was observed with an empty bladder. Monitoring of the inner orifice of the urethra withan empty bladder presents a slight problem. To evaluate vesicalisation of the proximal urethraand to confirm insufficiency of the inner sphincter (ISD), a filling in the bladder is necessary. Thethickness of the bladder wall is measured with an empty bladder.
