OBJECTIVE
To evaluate the measurement of intravesical prostatic protrusion (IPP) by transabdominal ultrasonography (TAUS) in the diagnosis of benign prostatic obstruction (BPO).
METHODS
We studied the clinical data of 109 BPH patients referred for lower urinary tract symptoms (LUTS) from April 2005 to December 2006. IPP was measured by TAUS, urodynamic parameters such as Qmax and PdetQmax obtained by urodynamic studies and AG values calculated. The patients were divided into an obstruction and a non-obstruction group according to their AG values.
RESULTS
IPP was found statistically different between the obstruction and non-obstruction groups (P<0.001) and positively correlated with the AG value (r=0.729, P=0.001). With the cutoff at IPP > or = 10 mm for the diagnosis of BPO, the sensitivity, specificity and accuracy of the diagnosis were 89.9%, 97.5% and 92.7%, respectively.
CONCLUSION
The measurement of IPP by TAUS offers a valuable help for the diagnosis of BPO.
目的
评估经腹部超声检查（TAUS）测量膀胱内前列腺突入（IPP）在良性前列腺梗阻（BPO）诊断中的价值。
方法
我们研究了2005年4月至2006年12月因下尿路症状（LUTS）转诊的109例良性前列腺增生（BPH）患者的临床资料。通过TAUS测量IPP，通过尿动力学研究获得尿动力学参数如最大尿流率（Qmax）和最大逼尿肌压（PdetQmax）并计算AG值。根据AG值将患者分为梗阻组和非梗阻组。
结果
梗阻组和非梗阻组的IPP在统计学上有差异（P<0.001），且与AG值呈正相关（r=0.729，P=0.001）。以IPP≥10mm作为BPO诊断的临界值，诊断的敏感性、特异性和准确性分别为89.9%、97.5%和92.7%。
结论
TAUS测量IPP对BPO的诊断有重要帮助。
