Purpose: We investigated the association between transient receptor potential vanilloid (TRPV) expression in human urothelium tissue and lower urinary tract dysfunction (LUTD). Materials and Methods: We prospectively enrolled men who planned to undergo surgical treatment for benign prostatic obstruction to analyze TRPV1 and TRPV4 expression in the urothelium using enzyme-linked immunosorbent assay and immunofluorescence staining. Patients were divided into two groups based on urodynamics: the detrusor underactivity (DU) group and the non-DU group. Levels of TRPV1 and TRPV4 were compared between the two groups. We also divided patients into two groups according to degree of subjective urinary urgency symptoms using a 5-point urinary sensation scale and compared the differences in TRPV1 and TRPV4 levels between the two groups. The correlations between urodynamic parameters with TRPV1 or TRPV 4 in all patients were also analyzed. Results: The levels of TRPV1 and TRPV 4 were not significantly different between the DU group (n=10) and the non-DU group (n=11). When we divided the patients according to degree of subjective urgency, the level of TRPV1 was not significantly different between the urgency group (n=10) and the non-urgency group (n =11), but the level of TRPV4 was significantly increased in the urgency group (p=0.029). There was no significant correlation between the level of TRPV1 or TRPV4 and urodynamic parameters in any patients. Conclusions: TRPV4 could be a useful diagnostic biomarker for patients with LUTD.
