To evaluate the association of intravesical prostatic protrusion (IPP) and overactive bladder (OAB) in male patients with lower urinary tract symptoms (LUTS). IPP has been suggested to correlate with storage symptoms in addition to bladder outlet obstruction. ⋯ IPP is not a good predictor of OAB in men presenting with LUTS. However, grade 3 IPP indicates higher frequency of nocturia.
