Aims The diagnosis of bladder outlet obstruction is made by pressure-flow studies, which is an invasive method. This study was conducted to evaluate non-invasive, effective, and low-cost diagnostic methods in male patients with bladder filling and emptying abnormalities.~Methods The study included 219 male patients aged 50 and over, who were admitted between March 2020 and August 2020. Patients completed the Visual Prostate Symptom Score (VPSS) along with International Prostate Symptom Score (IPSS). Intravesical prostatic protrusion (IPP), prostate volume, bladder volume, and post voiding residual urine (PVR) were measured by suprapubic ultrasound. Urethral resistance was calculated using the Bladder Outlet Obstruction Number (BOON), and patients over -20 were considered obstructed.
