摘要
目的：探讨膀胱内前列腺突入程度（IPP）与良性前列腺增生（BPH）患者发作急性尿潴留（AUR）次数的关系。方法：97例确诊为BPH的患者，按照发生AUR的次数分为A组（0次，54例）、B组（1~2次，36例）、C组（>2次，7例）3个组别。经腹B超（TAUS）测量IPP和前列腺体积（PV）。分别比较3组间IPP值、PV值的差异以及对IPP值和PV值做相关分析。结果：3组的年龄分布相同，差异不具有显著性（P>0．05）。A组与B组、C组的PV值比较有显著性差异（P<0．05），而B组和C组的比较无显著性差异（P>0．05）。A组IPP值为（5.61±4.30）mm，95%可信区间（CI）为4.44~6.79mm；B组IPP值为（17.69±6.00）mm，95%CI为15.66~19.73mm；C组IPP值为（30.71±12.84）mm，95%CI为18.84~42.59mm。3组IPP值的两两比较结果显示任意两个组的差别均有显著性（P<0．05）。PV值与IPP值相关性分析结果显示有明显的相关性（r=0.681，P<0．01）。结论：IPP值>7mm的患者易发作AUR，且IPP值>20mm的患者拔出导尿管后再发AUR的风险将会增加。采用简单、实用的TAUS评估IPP，对评价AUR、指导判断BPH严重程度和外科干预时机可能有重要的临床意义。
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.
