From: A prospective evaluation of the impact of trans-rectal prostate biopsy on the voiding function of patients

  1. All variables are expressed as mean ± standard deviation
  2. 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
  3. *p value (paired samples t test) < 0.05 is significant
