Urodynamic Studies: Uroflowmetry

Uroflowmetry is a non-invasive urodynamic test designed to measure various aspects of urination, including volume, flow rate, and the time to void. This test is crucial for diagnosing and assessing conditions such as bladder outlet obstruction, bladder dysfunction, incomplete bladder emptying, incontinence, and urinary tract blockages caused by benign prostatic hyperplasia (BPH) and urethral strictures.Pre-Test Instructions:Before a uroflowmetry test, patients are typically advised to drink...

Summary

Yōni.Fit, an intravaginal insert, effectively reduced stress urinary incontinence (SUI) symptoms and pad usage compared to a sham device. While adverse events were more frequent, they were generally mild, indicating potential as a nonsurgical SUI treatment.

Area of Science:

  • Urology
  • Gynecology
  • Medical Devices

Background:

  • Stress urinary incontinence (SUI) significantly impacts women's quality of life.
  • There is a demand for non-surgical treatment options for SUI.

Purpose of the Study:

  • To evaluate the safety and efficacy of Yōni.Fit, a novel intravaginal insert, for treating SUI.
  • To compare Yōni.Fit against a sham device in a randomized controlled trial.

Main Methods:

  • A multicenter, single-blind, randomized, sham-controlled trial was conducted.
  • Participants used either Yōni.Fit or a sham device daily for 12 hours.
  • The primary outcome was the responder rate, defined as a ≥50% reduction in pad weights.

Main Results:

  • Yōni.Fit demonstrated a significantly higher responder rate (53.0% vs. 23.3%, P=0.013) compared to the sham device.
  • A greater proportion of Yōni.Fit users achieved SUI responder status (96.3% vs. 27.2%, P<0.001).
  • Yōni.Fit was rated as more useful, though adverse events were more common but generally mild.

Conclusions:

  • Yōni.Fit is an effective nonsurgical treatment for SUI, significantly reducing symptoms and improving usefulness.
  • The device shows promise, but further research is needed to assess long-term safety and efficacy.
