A Repeatability Study of Measurement of Micturition With Voiding Sonography and Uroflowmetry of Asymptomatic Women
Aims
This study aimed to assess the intra- and inter-tester repeatability of voiding sonography measures in asymptomatic women and to examine the effect of perineal transducer placement on uroflowmetry.
Methods
A prospective observational study of 32 asymptomatic women was conducted using ultrasound with simultaneous uroflowmetry. Participants completed four voids (two per day). The ultrasound transducer placed on the perineum assessed bladder neck and urethral displacement during micturition. On Day 1, a void with ultrasound and uroflow recorded by a sonographer was compared to a void recorded with uroflowmetry only to determine whether the transducer placement affected voiding. On Day 2, two sonographers evaluated the voids with ultrasound and uroflowmetry. Each sonographer measured their own images. One sonographer also made measures on the images recorded by the second sonographer. Uroflowmetry measures and void patterns were evaluated. The repeatability of ultrasound measures was analyzed using intraclass correlation coefficient (ICC 2,1) and Bland–Altman analysis, and t tests examined the transducer's impact on uroflowmetry.
Results
Some changes in flow rate and flow pattern (20% of participants) were observed with placement of the transducer. Most sonographic measures showed good to excellent inter- and intra-tester repeatability, and between measures made by the different testers on the same image. During void, bladder neck and urethral diameter were more repeatable if measures were made at the time of maximum flow estimated from the simultaneous uroflowmetry.
Conclusion
Voiding sonography is both feasible and repeatable. Perineal transducer placement affected micturition for some individuals. Voiding sonography combined with uroflowmetry shows promise for a noninvasive urogynecology functional assessment.
期刊介绍：
LUTS is designed for the timely communication of peer-reviewed studies which provides new clinical and basic science information to physicians and researchers in the field of neurourology, urodynamics and urogynecology. Contributions are reviewed and selected by a group of distinguished referees from around the world, some of whom constitute the journal''s Editorial Board. The journal covers both basic and clinical research on lower urinary tract dysfunctions (LUTD), such as overactive bladder (OAB), detrusor underactivity, benign prostatic hyperplasia (BPH), bladder outlet obstruction (BOO), urinary incontinence, pelvic organ prolapse (POP), painful bladder syndrome (PBS), as well as on other relevant conditions. Case reports are published only if new findings are provided.
LUTS is an official journal of the Japanese Continence Society, the Korean Continence Society, and the Taiwanese Continence Society. Submission of papers from all countries are welcome. LUTS has been accepted into Science Citation Index Expanded (SCIE) with a 2011 Impact Factor.
