The impact of neuropathic pain in the chronic pelvic pain population.

Purpose: Patients with chronic pelvic pain disorders often present with neuropathic features. We examined a cohort of patients with a primary complaint of chronic pelvic pain for the presence of neuropathic pain symptoms.

Materials And Methods: Patients with chronic pelvic pain disorders from 2 tertiary referral centers were prospectively evaluated. The validated S-LANSS (Self-Administered Leeds Assessment of Neuropathic Symptoms and Signs) survey was used to examine pain symptoms of neuropathic origin. Patients completed SF-12v2™ to assess mental/physical health domains. The 2-tailed t test and chi-square analysis were used to compare physical and mental component summaries in patients with vs without neuropathic symptoms.

Results: A total of 142 patients mean age of 45 years were included in analysis. Of the patients 72.5% with chronic pelvic pain carried more than 1 primary diagnosis. The S-LANSS survey identified symptoms suggestive of neuropathic pain in 44 patients (31%). A greater proportion of patients with a neuropathic component had altered sensation in the affected area (86.4% vs 24.5%). Patients with neuropathic pain scored 4.28 and 5.45 points lower on the physical and mental component summaries (p = 0.053 and 0.008, respectively).

Conclusions: A large proportion of patients with chronic pelvic pain present with neuropathic features and report decreased quality of life compared with the general population. Those with neuropathic symptoms have significantly lower quality of life than those without such symptoms. Clinicians can identify patients to use targeted therapies and use a multidisciplinary approach to care.
