Cystometrograms obtained at 28 days after induction of prostatic inflammation. The mean number of NVCs was significantly greater in formalin-vehicle rats (Formalin) than that in sham-saline rats (Sham) (P < 0.05), and VI was significantly decreased in formalin-vehicle rats compared to sham-saline rats (P < 0.05). The 3α-Adiol administration in formalin-treatment rats (Treatment) recovered these changes. There was no significant difference in MVP and RV among three groups. VI, voiding Interval; NVCs, non voiding contractions; MVP, maximum voiding pressure; RV, residual volume; N = 5 per group. P < 0.05 between groups.
