Association between self-perception period of lower urinary tract symptoms and International Prostate Symptom Score: a propensity score matching study.

Background Most studies focusing on progression of BPH have been limited to the relationship between age and BPH progression, and only few studies have focused on the time duration to start treatment. This study aimed to investigate the association between self-perception period (S-PP) of lower urinary tract symptoms (LUTS) and International Prostate Symptom Score (IPSS).
