超声测定膀胱内前列腺突出长度与良性前列腺增生患者膀胱出口梗阻的关系

目的了解膀胱内前列腺突出(IPP)长度与良性前列腺增生(BPH)患者膀胱出口梗阻(BOO)的关系,探讨诊断BOO的简便方法。方法选择41例临床确诊的BHP患者,进行国际前列腺症状评分(IPSS),行腹部超声检查测量IPP长度,同时行尿流动力学检查测量残余尿(PVR)、最大尿流率(Qmax)、排尿期最大逼尿肌压力(PdetQmax),并计算AG值。结果 41例BHP患者中,18例患者IPP<10mm,23例患者IPP≥10mm。与IPP<10mm的BHP患者比较,IPP≥10mm的BHP患者IPSS较高[(21.06±5.97)分vs(15.28±3.21)分],Qmax较低[(7.99±1.72)ml/svs(11.06±3.11)ml/s],且差异均有统计学意义(t值分别为-4.495、3.857,P均<0.01);IPP≥10mm的BHP患者PVR高于IPP<10mm的BHP患者[(85.39±45.02)mlvs(60.05±40.68)ml],但差异无统计学意义。18例IPP<10mm的BHP患者中,7例患者AG<40,11例患者AG>40;23例IPP≥10mm的BHP患者中,2例患者AG<40,21例患者AG>40。与IPP<10mm患者比较,IPP≥10mm患者BOO梗阻情况更严重,且差异有统计学意义(χ2=8.637,P<0.01)。结论 IPP长度可以区分BPH患者是否存在BOO。IPP长度联合Qmax可作为诊断BOO的简便方法 。

Relation between the length of intravesical prostatic protrusion and bladder outlet obstruction in benign prostatic hyperplasia patients

Objective To analyze the relationship between the length of intravesical prostatic protrusion （IPP） and bladder outlet obstruction （BOO） in patients with benign prostatic hyperplasia （BPH） and explore a simple method for the diagnosis of the disease. Methods The length of IPP were measured by transabdominal ultrasound in 41 patients diagnosed with BPH, Qmax, PVR and PdetQmax was measured by urodynamie tests and the AG was calculated. Results Among the 41 BHP patients, 18 patients had IPP 〈 10 mm and 23 ones had IPP~〉10 mm. Compared with the patients whose IPP 〈 10 mm, international prostate symptom （IPSS） score of the patients that IPP I〉 10 mm were higher E （21.06 ± 5.97 ） scores vs （ 15.28 ± 3.21 ） scores] , and Qmax were lower[ （7.99 ± 1.72） rn/s vs （ 11.06 ± 3. 11 ） m/s ] , both results showed statistically difference（ t = -4. 495, 3. 857, both P 〈 0.01 ）. PVR of the patients whose IPP〉~ 10 mm were higher than the IPP 〈 10 mm cases I （ 85.39 ± 45.02） ml vs （60.05 -± 40.68 ） ml ], with no statistical significance. Of the 18 patients that IPP 〈 10 mm, 7 patients had AG 〈40, and 11 patients had AG 〉40; 2 of the 23 patients whose IPP i〉 10 mm had AG 〈 40, other 21 patients showed AG 〉 40. BOO of the IPP I〉 10 mm patients were more serious than the IPP 〈 10 mm cases, with significance difference （x2 = 8. 637,P 〈 O. O1 ）. Condusions The length of IPP can predict the existence of BOO, with the combination of Qmax. It can be used for the diagnosis of BOO in BPH patients.
