A-G图及AG数诊断膀胱出口梗阻的应用价值

Clinical value of diagnosis for bladder outflow obstruction using A-G nomogram and AG number

为了探讨A－G图及AG数诊断及定量判断膀胱出口梗阻（BOO）及其临床应用价值，对205例前列腺增生（BPH）患者进行压力-流率测定。结果表明：171例患者被诊断为BOO，34例为非梗阻；151例患者位于A－G图梗阻区（O区），39例位于可疑区（E区），15例位于非梗阻区（U区）。E区患者中，20例为梗阻者，19例为非梗阻者；O区、E区、U区患者AG数分别为195．6±38．2、32．3±5．8及-32．4±15．6。32例前列腺摘除术患者术后AG数降低203．3±23．6，O区病例数降低26例，U区病例数增加29例。认为在临床工作中，使用A－G图诊断BOO以及使用AG数对BOO进行定量判断具有重要意义；

To use A-G nomogram and AG number for diagnosing and quantitating the bladder outflow obstruction (BOO), 205 patients with benign prostatic hyperplasia (BPH) underwent the pressure-flow studies. The results showed that 171 of 205 patients were diagnosed as BOO, 34 unobstructed; 151 patients located on the obstructed area, 39 the equivocal one, 15 the unobstructed one; 20 patients were obstructed and 19 unobstructed in the patients located on equivocal area;AG number on obstructed,equivocal and unobstructed area was respectively 195. 6±38. 2, 32. 3±5. 8,-32. 4±15. 6. The AG number reduced 203. 3±23. 6, the patients located on obstructed aera reduced 26 cases and the patients on unobstructed aera increased 29 cases post opertion in 32 patients unde-rgone prostatectomy. lt was important that BOO was diagnosed using A-G nomogram and BOO was quantitated using AG unmber in clinical works.
