PURPOSE OF REVIEW: Urologic pain conditions such as chronic prostatitis/chronic pelvic pain syndrome, interstitial cystitis/bladder pain syndrome and chronic orchialgia are common, yet diagnosis and treatment are challenging.
Current therapies often fail to show efficacy in randomized controlled studies. Lack of efficacy may be due to multifactorial causes and heterogeneity of patient presentation. Efforts have been made to map different phenotypes in patients with urologic pain conditions to tailor more effective therapies. This review will look at current literature on phenotype classification in urologic pain patients and their use in providing effective therapy.
RECENT FINDINGS:There has been validation of the 'UPOINT' system (urinary symptoms, psychosocial dysfunction, organ specific findings, infection, neurologic/systemic and tenderness of muscle) to better categorize male chronic prostatitis/chronic pelvic pain syndrome and interstitial cystitis/bladder pain syndrome. Refinement of domain systems and recent cluster analysis has suggested possible central processes involved in urologic pain conditions similar to systemic pain syndromes such as fibromyalgia, chronic fatigue and irritable bowel syndrome.
SUMMARY:Domain characterization of urologic pain conditions via phenotype mapping can be used to better understand causes of chronic pain and hopefully provide more effective, targeted and multimodal therapy.
