Recruiting at 2 sites in Israel. Open to female participants aged 18 Years to 99 Years. Per ClinicalTrials.gov, last updated 2026-03-25.

Study 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 underwent benign vaginal surgeries.

What researchers measure

Primary outcomes

  1. Post-void residual volume>150 CC

    after the first void following catheter removal

    Time frame: The following 7 days after surgery

Secondary outcomes

  1. Success rate of voiding trial

    no need for recatheterization

    Time frame: The following 7 days after surgery

  2. Pain during micturition

    Pain during micturition, using The Visual Analogue Scale (VAS) 0-10. O means no pain, 10 means worst pain imaginable.

    Time frame: The following 7 days after surgery

  3. UTI

    in the 7 days following the surgery

    Time frame: The following 7 days after surgery

  4. Urinary retention

    REST\>150 ml

    Time frame: The following 7 days after surgery

  5. Post-void residual volume

    in ml

    Time frame: The following 7 days after surgery
