Introduction:
Benign prostrate hyperplasia (BPH) is a leading source of healthcare problem in aging men around the world including India. Both International Prostate Symptom Score (IPSS) and New Visual Prostate Symptom Score (VPSS) are used to assess the lower urinary tracts symptoms (LUTSs) in men. The present study was planned to compare these two scores, IPSS and VPSS in Indian rural men prospectively and their efficacy was compared with urodynamic evaluation of the patients.
Materials And Methods:
With Institutional Ethical Committee approval, this study was conducted on 100 patients having LUTS and BPH after obtaining written informed consent. Patients' educational status was noted. All the patients were requested to complete the IPSS and VPSS questionnaire, and they were correlated. The urodynamic study was performed on all the patients with uroflowmeter. Two parameters of uroflowmetry, Qmax (maximum urine flow rate expressed in ml/s) and Qavrg (average urine flow rate expressed in ml/s) were measured and correlated.
Results:
Most of the patients (55%) in this study were uneducated. Out of 100 patients, 83% were able to fill the VPSS questionnaire without assistance as compared to only 40% patients in IPSS questionnaire (Z = 6.557, P < 0.001). There was a positive correlation between IPSS and VPSS total score in this study (r = 0.453 and P ≤ 0.001). It was noticed that IPSS Question 2 for frequency of urination had a positive correlation with VPSS Question 1 (day time frequency of urination) r = 0.645 (P = 0.000). Similarly, IPSS Question 7 for night frequency when compared with VPSS Question 2 (nocturia); the value for r was found to be 0.536 (P = 0.000). The IPSS Question 5 for straining when compared to the VPSS Question 3, i.e., the question for the strength of stream during micturition; the positive correlation was found to be 0.266 (P = 0.007). There was a negative correlation between IPSS total score and Qavrg with value - 0.368 (P = 0.000) and between IPSS total score and Qmax of - 0.433 (P = 0.000). A negative correlation is also noted between VPSS total score and Qavrg of value 0.497 (P = 0.000) and VPSS total score and Qmax of value - 0.719 (P = 0.000).
Conclusion:
VPSS correlates significantly with the IPSS to quantify the LUTS due to BPH. The VPSS can be used instead of the IPSS for the assessment of symptom severity in men with LUTS, who are illiterate or have limited education.
