Abstract

Purpose: In men, lower urinary tract symptoms (LUTS) similar to interstitial cystitis/bladder pain syndrome (IC/BPS) are difficult to diagnose, and treatment outcomes are poor. This study investigated clinical characteristics and videourodynamic study (VUDS) parameters, pathophysiology, and treatment outcomes in men with IC-like LUTS.

Methods: Men with frequency, urgency, dysuria, and bladder pain initially diagnosed as IC/BPS by ESSIC criteria were assessed to rule out other lower urinary tract diseases (LUTD) by voiding diary, digitorectal examination, urinalysis, VUDS, and cystoscopic hydrodistention. Subsequent treatments for LUTD and specific treatment for IC/BPS were based on VUDS and cystoscopic findings. Clinical VUDS characteristics and treatment outcomes were compared with those of women with IC/BPS.

Results: Seventy consecutive men (median age 54.5 years) were enrolled. The median maximum bladder capacity under cystoscopic hydrodistention was 650 mL (IQR 495-763) and glomerulation grade was 2 (1.0-2.0). The patients had moderate anxiety and depression severity; 49% had improved treatment outcomes. On VUDS, 42 (60%) patients had variable LUTD, including detrusor overactivity (n = 14), bladder neck dysfunction (n = 15), dysfunctional voiding (n = 3), and poor relaxation of the external sphincter (n = 24); also, 22 (31.4%) had a previous bladder outlet procedure. The self-reported treatment outcome was significantly better for patients with vs. without LUTD (p = 0.014).

Conclusions: Men with IC-like LUTS diagnosed as IC/BPS may have bladder outlet dysfunction as well as bladder dysfunction, causing a hypersensitive and painful bladder. The IC-like symptoms in the patients with LUTD might, in part, originated from bladder outlet dysfunction rather than the bladder alone.
