Lower urinary tract symptoms associated with prostatitis.

Author(s): J. Curtis Nickel, MD, FRCSC

Lower urinary tract symptoms (LUTS) associated with pain (e.g., prostatitis) tend to have a more substantial impact on patient quality of life than other LUTS presentations. There are several categories of prostatitis, each with their own clinical profile in terms of the expected symptom types (pain, voiding, storage). Furthermore, one can characterize the types of symptoms seen in prostatitis through the use of a novel mnemonic (UPOINT). Making treatment decisions according to the presence or absence of each of the UPOINT symptom types has been associated with excellent results. The following review outlines this phenotypic approach to prostatitis and the results that have been reported to date when treating according to this approach.

LUTS and pain in prostatitis: Overview

There are four categories of prostatitis: acute bacterial prostatitis (category I), chronic bacterial prostatitis (category II), chronic prostatitis/chronic pelvic pain syndrome (category III), and asymptomatic prostatitis (category IV). Each of these categories has a different profile with respect to LUTS (Table 1).

Overall, investigation of an international prostatitis database showed that 50% to 60% of men in the database had urinary LUTS.[sup.1] The most common sites of pain were perineal (63.3% of patients), and testicular (57.6%). Other commonly reported sites were ejaculatory pain (44.7%), dysuria (43.3%), pubic area (42.3%) and the tip of the penis (32.4%).[sup.1] The most bothersome of these was ejaculatory pain. The variables found to be associated with reduced quality of life in this study were increased pain severity, increased pain frequency and number of pain localizations.

Recommended evaluation of prostatitis

The Canadian Urological Association (CUA) guidelines[sup.2] on prostatitis, published in 2011, recommend that the evaluation of men with symptoms of prostatitis include a detailed history and, for chronic cases, the use of the National Institutes of Health chronic prostatitis symptom index (NIH-CPSI).[sup.3] In the history, the assessment should include characterization of pain (location, severity, frequency, and duration) and LUTS (obstructive/voiding and irritative/storage), as well as other associated symptoms (e.g., fever, other pain syndromes) and the impact of the symptoms on activities and quality of life. Furthermore, the comprehensive systems review should document past medical and surgical (particularly urologic) history, history of trauma, medications and allergies.

Use of the NIH-CPSI is important in that it affords patients the opportunity to tell their physician how severe they perceive their pain or symptoms to be. It is also useful as a way to measure change over time and monitor the effectiveness of treatment.

Prostatitis treatment

For chronic prostatitis and chronic pelvic pain syndrome, the CUA guidelines include a treatment algorithm that outlines a number of different treatment modalities (Fig. 1).[sup.2] Taken individually, each of these interventions has been shown to have a statistically significant, but not necessarily clinically relevant, beneficial impact on symptoms.[sup.4] Collectively, however, use of the appropriate treatments can have a substantial benefit on symptoms and overall quality of life. Avoidance of any identified causes or triggers is also an important part of overall management.

UPOINT

As mentioned above, there is now a novel approach to the characterization of patients with prostatitis that seeks to maximize the impact of pharmacotherapy through the identification of specific phenotypes that are likely to respond to a given therapy. The UPOINT mnemonic stands for Urinary, Psychosocial, Organ-centric, Infection, Neurogenic/systemic and Tenderness. Research has shown that if patients are identified by UPOINT phenotype and treated accordingly (Fig. 2), there is an 84% response rate (response defined as a six-point fall in CPSI), with a CPSI decrease of 12 points, from 25.2 to 13.2.[sup.5]

Conclusion

Traditional therapies for LUTS associated with chronic pelvic pain syndrome can be effective if they are used in new evidence- and rationale-based strategies.
