Weak correlation between bladder outlet obstruction and probability to void to completion.

Summary

Bladder outlet obstruction (BOO) alone poorly predicts postvoid residual urine volume. Combining bladder outlet resistance with bladder contractility significantly improves prediction accuracy for voiding completion.

Area of Science:

  • Urology
  • Men's Health
  • Lower Urinary Tract Symptoms

Background:

  • The provisional International Continence Society (ICS) nomogram is used to diagnose bladder outlet obstruction (BOO) in men.
  • A weak correlation has been observed between BOO diagnosis and postvoid residual urine volume (PVR).

Purpose of the Study:

  • To investigate the weak correlation between BOO and PVR.
  • To determine if incorporating bladder contractility improves PVR prediction.

Main Methods:

  • 131 male patients underwent pressure flow studies.
  • Multivariate logistic regression analysis was used to assess the relationship between voiding to completion and various resistance and contractility indexes.

Main Results:

Related Experiment Videos

  • The ICS nomogram and BOO index showed weak predictive power for PVR (AUC 0.63-0.64).
  • Augmenting the BOO index with bladder contractility significantly improved PVR prediction (AUC 0.89).

    • Conclusions:

    • Bladder emptying depends on both outlet resistance and contractility.
    • A new index, "relative bladder outlet resistance," combining these factors, accurately predicts voiding completion and PVR.
    • This improved prediction offers a better understanding of "relative BOO."
