Abstract
The current study was conducted at Ain Shams
University Maternity Hospital from September 2014 to
December 2015. After informed written consent was
obtained from each participant prior to inclusion criteria in
the study.
The aim of this study was to determine the
effectiveness of three dimension transvaginal ultrasound in
diagnosis of stress urinary incontinence in comparison to
urodynamic study.
The current study included 140 patients divided into
two groups, a case group which suffer from SUI diagnosed
by history and urodynamic study and a control group
which is normal patients which mainly infertile patients,
with mean age 53.1±6.5 in case group and 51.9±3.9 in
control group, and with mean BMI 28.4±3.6 in case group
and 27.2±.3 in control group.
Regarding to the results of this study 65 (92.8%)
patients in case group and 5 (7.1%) patients in control
group have IUS tear by 3DUS, we found that 21 (30%)
patients have distal tear, 13(18.5%) patients have proximal
tear and 31 (44.2%) patients have proximal and distal tear
in 3DUS. With 92.9% specificity, 82.9% sensitivity, 92.1% positive predictive value and 84.4% negative predictive
value of 3DUS in diagnosing SUI. And there was mild to
moderate agreement between 3DUS and urodynamic study
as evidenced by a Cohen Kappa Coefficient of 0.473 (95%
CL, 0.297 to 0.648).
