Summary

Prostatitis and interstitial cystitis share symptoms, suggesting a common lower urinary epithelial dysfunction. Most prostatitis patients exhibit positive potassium sensitivity tests, similar to interstitial cystitis patients.

Area of Science:

  • Urology
  • Nephrology
  • Pathophysiology

Background:

  • Prostatitis and interstitial cystitis present overlapping symptoms.
  • Urinary epithelial dysfunction is common in interstitial cystitis, indicated by potassium sensitivity tests.
  • This study investigates epithelial dysfunction in prostatitis patients.

Purpose of the Study:

  • To assess urinary epithelial dysfunction in men diagnosed with prostatitis using the potassium sensitivity test.
  • To explore the relationship between prostatitis and interstitial cystitis.

Main Methods:

  • Administered the potassium sensitivity test to 44 men diagnosed with prostatitis.
  • Collected data on urinary symptoms and pain locations via self-evaluation questionnaires.
  • Patients had already received at least one course of antibiotic treatment.

Main Results:

  • 84% of prostatitis patients had positive potassium sensitivity test results.
  • 89% reported urinary urgency/frequency, and 82% reported pelvic pain.
  • 75% experienced pain during sexual intercourse.

Conclusions:

  • The high rate of positive potassium sensitivity tests in prostatitis mirrors that in interstitial cystitis.
  • Prostatitis and interstitial cystitis may represent a spectrum of lower urinary epithelial dysfunction.
  • Reclassifying this condition as 'lower urinary dysfunctional epithelium' is suggested.
