Variables	Timing in relation to prostate biopsy			p values*
Variables	D0	D7	D14	D0 versus D7	D7 versus D14	D7 versus D14
IPSS-T	12.5 ± 7.2	14.7 ± 8.2	11.3 ± 8.1	0.003	0.001	0.138

Bother Score	3.3 ± 1.6	3.6 ± 1.7	2.9 ± 1.7	0.025	0.001	0.072

All variables are expressed as mean ± standard deviation
IPSS: International Prostate Symptom Score, IPSS-T: total IPSS score, IPSS-S: IPSS storage symptoms sub-score, IPSS-V: IPSS voiding symptoms sub-score, PFR: peak flow rate, D0: baseline values, D7: 7th day post-biopsy values, D14: 14th day post-biopsy values
*p value (paired samples t test) < 0.05 is significant
