Diagnostic Role of Intravesical Prostatic Protrusion and Visual Prostate Symptom Score in Lower Urinary Tract Symptoms in Male

INTRODUCTION: In this study, it was aimed to evaluate non-invasive, effective and low-cost diagnostic methods of bladder filling and voiding abnormalities in male patients. METHODS: Visual Prostate Symptom Score (VPSS) and the International Prostate Symptom Score (IPSS) were completed by the patients. Patients' intravesical prostatic protrusion (IPP), prostate volume, and post voiding residual urine (PVR) were measured by suprapubic ultrasound. Bladder Outlet Obstruction Number (BOON) was used to calculate urethral resistance. Patients with a BOON value above -20 were considered obstructive. RESULTS: This study included 219 male patients aged 50 years and over.The number of patients with a BOON value over -20 were 34 (obstructed) and below -20 were 61 (non-obstructed). There was a significant difference between these two groups in terms of PSA, prostate volume, IPP, Qmax, PVR, IPSS, and VPSS. It was observed that IPSS and VPSS were correlated (r=0.786, p=0.001). Obstructive (r=0.779, p=0.000) and irritative symptoms (r=0.813, p=0.000) of IPSS and VPSS were also observed to be correlated. DISCUSSION AND CONCLUSION: VPSS was found to be equivalent to IPSS in the diagnosis of lower urinary tract symptoms (p=0.001). IPP is an important, practical, and non-invasive method that correlates with IPSS, VPSS, and BOON.
