Correlation of intravesical prostatic protrusion with clinical evaluation parameters in BPH patients / 中华男科学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the correlation of the degrees of intravesical prostatic protrusion (IPP) measured by transabdominal ultrasound with the clinical evaluation parameters in BPH patients.</p><p><b>METHODS</b>We measured the length of IPP in the mid-sagittal section by transabdominal ultrasound in 275 BPH outpatients with lower urinary tract symptoms, and analyzed the correlations of the degree of IPP with the age, prostatic volume (PV), international prostatic symptom score (IPSS), maximum uroflow rate (Qmax), and postvoid residual urine volume (PVR) of the patients.</p><p><b>RESULTS</b>The degree of IPP was correlated positively with the age (r = 0.210, P < 0.01), PV (r = 0.534, P < 0.01) and PVR (r = 0.314, P < 0.01), but negatively with the Qmax (r = -0.364, P < 0.01) of the BPH patients. There was no significant correlation between the degree of IPP and IPSS (r = 0.064, P = 0.299).</p><p><b>CONCLUSION</b>The degree of IPP may be associated with the age and prostatic volume of BPH patients. Transabdominal ultrasound measurement of IPP is a useful noninvasive method to assess the presence and severity of bladder outlet obstruction in BPH patients.</p>
