Bladder diverticula, outpouchings in the bladder wall, are common in men with prostatism. These diverticula correlate with age and can lead to upper urinary tract dilation.

Area of Science:

  • Urology
  • Diagnostic Imaging

Background:

  • Bladder diverticula are outpouchings of the bladder wall.
  • Their incidence and clinical significance in patients with prostatism require further investigation.

Purpose of the Study:

  • To determine the incidence of bladder diverticula in patients referred for prostatism.
  • To explore the associations between bladder diverticula and patient age, imaging findings, and urodynamic parameters.

Main Methods:

  • Retrospective analysis of 104 patients referred for prostatism.
  • Cystography and urography performed on 69 patients.
  • Correlation analysis with age, upper tract dilatation, residual urine volume, bladder instability, bladder neck-verumontanum distance, maximal flow rate, and bladder capacity.

Main Results:

  • Bladder diverticula were detected in 51% of patients by cystography and 30% by urography.
  • Diverticula incidence significantly increased with age.
  • A significant association was found between diverticula and upper tract dilatation.
  • Diverticula showed a tendency towards association with increased residual urine volume and bladder instability.

Conclusions:

  • Bladder diverticula are frequently observed in patients with prostatism, with cystography being more sensitive than urography for detection.
  • Age is a significant factor in diverticula development.
  • The presence of bladder diverticula is associated with upper urinary tract changes and may be linked to bladder dysfunction.
