ABSTRACT
Objective: To investigate the relationship between the Post-Void Residual (PVR) volume and severity of Lower Urinary Tract Symptoms (LUTS) in a sample of patients of a Sri Lankan population. Method: This is a descriptive, cross-sectional study performed using the data obtained from patients attending the urology laboratory at the University of Peradeniya, Sri Lanka. International Prostate Symptom Score (IPSS) was used to assess the severity of LUTS in patients. PVR values were collected from the reports given by the urology laboratory. Data analysis was performed using Pearson test and graphical analysis. Results: Study group consisted of 297 patients where 88.1% of the group was male and 11.9 % was female. Incomplete evacuation, intermittency, frequency and total IPSS showed a significant correlation with both PVR and the percentage of PVR. Highest correlation was observed between incomplete evacuation and PVR (.347). When the percentage of PVR out of Pre-Void Volume (PVV) was plotted against total IPSS score in males and females separately, a distinct pattern was shown only in males. Conclusions: Severity of LUTS is significantly correlated with PVR volume. That relationship is clearly visible when the PVR volume is measured as a percentage of PVV. Correlation between total IPSS and PVR volume is distinct in males than in females.
