Voiding Function Clinical Trial
Official title:
Influence of the Urine Stream Interruption Exercise on the Micturition
This study assess micturition characteristic during and after a urine stream interruption exercise in patient without neurological or urologic disease.
Urine stream interruption during voluntary voiding is often performed by women as a pelvic
floor muscle exercise to develop urinary strength and avoid urinary incontinence. To our
knowledge, there is no recommendation for performing urine stream interruption. Without
evidence based data, stooping the urinary flow is reported as a risk of post void residual
and urinary infection. The experts did not recommended to practice urine stream interruption
as a pelvic floor exercise in urinary incontinence. However, during pelvic floor muscle
training for urinary incontinence, exercises of urine stream interruption are often performed
without knowledge of their consequences. The aim of this study is to assess micturition
characteristic during and after a urine stream interruption exercise.
In this study, the investigators will compare the two uroflowmetries usually done in a
Neuro-urology department of a University Hospital. Patient without neurological or urologic
disease, consulting for a global evaluation of functional digestive disease and performing an
urodynamic study will be included. During the urodynamic evaluation, two uroflowmetries are
performed : one conventional uroflowmetry complying with the International Continence Society
(ICS) recommendations and one uroflowmetry during exercise of urine stream interruption, as
usually done in the department. Each uroflowmetry will be performed when the patient will
feel a ''normal'' desire to void. For the urine stream interruption micturition, patients
will be asked to "begin the micturition, stop at 3 seconds of micturition, when the stream is
interrupt, start again voiding, again stop at 3 seconds of micturition and repeat this
maneuver until the end of the micturition". As usual, sonographic estimation of post-void
residual volume will complete each uroflowmetry.
The investigators will compare the voiding volume, the post-void residual volume, the maximal
flow rate, the time to reach the maximal flow rate, the voiding time and the slope of the
uroflowmetry (corresponding to the flow velocity acceleration) between the two
uroflowmetries. For each voiding sequence of the urine stream interruption micturition the
following parameters will be reported and compared: voiding volume and duration, maximal flow
rate, time to reach the maximal flow rate, the latency to restart the micturition between
each voiding sequence and the slope of the uroflowmetry.
Statistical analysis will be carried out using R 3.2.3 software (R Development Core Team,
http://www.R-project.org) and R studio version 1.0.136. Differences between the two
uroflowmetries will be evaluated using Student test. Correlation between the place of the
voiding sequence in the urine stream interruption micturition and the different parameters
will be evaluated using Pearson's correlations.
