Correlation Between Residual Volume of Male Patients After Uroflowmetry and Random Residual Volume

Objectives Our aim was to examine correlation between Post‐void residual urine (PVR) after uroflowmetry and random PVR. Methods Male patients reporting to the Urology outpatient clinic with LUTS were selected. Patients' age, prostate volume, bladder capacity, voided volume, maximum flow rate, average flow rate, random PVR and PVR after uroflowmetry were recorded. We evaluated the correlations between these parameters. Also we assessed if there was a difference between random PVR and PVR after uroflowmetry. We divided PVR after uroflowmetry and random PVR into three groups: Group 1: 0–50 mL, Group 2: 51–100 mL and Group 3: >100 mL. Also we divided the patients into two groups according to bladder capacity as Group 1: ≤400 mL and Group 2: >400 mL. We compared these groups to determine whether a significant difference. Results Seventy‐seven patients applying to the urology outpatient clinic were assessed between 2013 and 2014. PVR after uroflowmetry was significantly higher than random PVR (P 400 mL, PVR after uroflowmetry was different, but random PVR was similar (P
