Abstract：To investigate the relationship between the degree of intravesical prostatic protrusion(IPP) and acute urine retention(AUR)． Methods: According to the occurrences of AUR, 97 benign prostatic hyperplasia(BPH) patients were divided into 3 groups． Group A included 54 patients who had never underwent AUR, and group B included 36 patients who had surffered AUR once or twice, while group C, the remaining 7 had suffered AUR at least three times. The IPP and prostatic volume(PV) was measured by transabdominal ultrasound(TAUS). We compared the clinical data of the three groups. Results: In the clinical data, there was statistical significance in the PV between A and B or A and C groups(P<0.05). But there was no significance in the PV between B and C groups(P<0.05). The degree of IPP has strong statistical significance between the three groups(P<0.05)． There was positive correlation between IPP and PV(r=0.681, P<0．01). Conclusions: The IPP can reflect the changes of PV, the presence and severity of bladder outlet obstruction． The IPP assessed by TAUS has important clinical significance to determine the severity of BPH and occurrence of AUR.
