Relationship of Sex and Diagnosis With Symptoms and Illness Impact in Urologic Chronic Pelvic Pain; A Mapp Network Analysis.

OBJECTIVE

To assess differences in clinical presentation and illness impact in men and women presenting with urologic chronic pelvic pain syndrome (UCPPS) and between men diagnosed with interstitial cystitis/bladder pain syndrome (IC/BPS) or chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS).

METHODS

356 men and 605 women from six sites across the United States were assessed using a comprehensive set of demographic, symptom, and illness impact measures. Multivariable regression analyses examined differences between men and women and between men previously diagnosed with CP/CPPS or IC/BPS. In a stepwise manner, analyses tested group differences, controlling for demographic variables including symptom duration and presence of bladder pain that varied with filling and voiding.

RESULTS

Men diagnosed with IC/BPS had the most severe UCPPS symptoms, followed by women with IC/BPS, and then men with CP/CPPS only. While men and women showed similar patterns of symptoms across most of the variables, women had increased widespread non-pelvic pain, greater pelvic floor tenderness on exam, and higher self-reported sensory sensitivity compared to men. About 60% of men diagnosed with CP/CPPS only reported bladder symptoms of painful filling or relief with voiding.

CONCLUSIONS

A generally shared symptom pattern was found across men and women irrespective of diagnostic labels suggesting the use of key marker symptoms, such as severity of bladder symptoms and widespread pain, to better identify subgroups of UCPPS rather than diagnostic category. Women may have an increased likelihood of increased sensitivity and central sensitization than men, including those men with IC/BPS.
