Effect of Voiding Position (Standing in the Shower vs. Sitting) on Post-Void Residual Urine Volume (PVR) After Removal of Urinary Catheter in Women Following Benign Vaginal Gynecologic Surgery
A study testing Voiding position - Standing in the shower and Voiding position - Sitting on the toilet in people with Post-void Residual Volume and Recatheterization, run by Assuta Ashdod Hospital at 2 sites in Israel.
Trial summary
The goal of this clinical trial is to learn if voiding in a standing position in the shower, rather than sitting on a toilet, may reduce pain associated with the act of voiding, thereby facilitating micturition and decreasing both post-void residual volume and the risk of subsequent urinary retention in women that… Read more about this study

About this study
Official title: Effect of Voiding Position (Standing in the Shower vs. Sitting) on Post-Void Residual Urine Volume (PVR) After Removal of Urinary Catheter in Women Following Benign Vaginal Gynecologic Surgery: A Double-Blind Randomized Controlled Trial
The goal of this clinical trial is to learn if voiding in a standing position in the shower, rather than sitting on a toilet, may reduce pain associated with the act of voiding, thereby facilitating micturition and decreasing both post-void residual volume and the risk of subsequent urinary retention in women that underwent benign vaginal surgeries.
- Conditions
- Post-void Residual Volume, Recatheterization, Pain, UTI, Urinary Retention
- Being tested
- Voiding position - Standing in the shower, Voiding position - Sitting on the toilet
- Medical subject headings
- Pain, Urinary Retention
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Voiding position - Standing in the showerBehavioural
After the removal of urine catheter, for the first micturation the woman will stand in the shower with the water on her vulvar area
Voiding position - Sitting on the toiletBehavioural
After the removal of urine catheter, for the first micturation the women will sit on the toiled
| Study group | Role | What they receive |
|---|---|---|
| Voiding position - Standing in the shower | Other | After removal of urine catheterization, during first micturation, the patient will stand in the shower with the water on her vulvar area Receives: Behavioral: Voiding position - Standing in the shower |
| Voiding position - Sitting on the toilet | Other | After the removal of urine catheter for the first micturation - the patient will sit on the toilet Receives: Behavioral: Voiding position - Sitting on the toilet |
What is being measured
The primary outcome is the main question the study is designed to answer.
Post-void residual volume>150 CC
after the first void following catheter removal
Measured: The following 7 days after surgery
Secondary outcomes (5)
Success rate of voiding trial
no need for recatheterization
Measured: The following 7 days after surgery
Pain during micturition
Pain during micturition, using The Visual Analogue Scale (VAS) 0-10. O means no pain, 10 means worst pain imaginable.
Measured: The following 7 days after surgery
UTI
in the 7 days following the surgery
Measured: The following 7 days after surgery
Urinary retention
REST>150 ml

Questions about this trial
What is this clinical trial studying?
A study testing Voiding position - Standing in the shower and Voiding position - Sitting on the toilet in people with Post-void Residual Volume and Recatheterization, run by Assuta Ashdod Hospital at 2 sites in Israel.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 25 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in Israel. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does the primary outcome measure?
Post-void residual volume>150 CC (time frame: The following 7 days after surgery). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
