【摘要】：背景： 兒童陰莖顯露不良是指陰莖不能顯露或不能完全顯露的一組疾病，隱匿陰莖包含其中。目前，疾病的診斷及療效評(píng)估主要依靠醫(yī)生主觀判斷，缺乏客觀指標(biāo)。本研究旨在數(shù)據(jù)統(tǒng)計(jì)的基礎(chǔ)上，探討一項(xiàng)客觀標(biāo)準(zhǔn)，，以用于臨床對(duì)隱匿陰莖的診斷及療效評(píng)估。 材料和方法： 選擇2012年6月到2013年3月門診行包皮環(huán)切術(shù)的包莖患兒55例（B組，對(duì)照組，年齡2.5歲~14歲）和住院行陰莖整形術(shù)的隱匿陰莖的患兒58例（A組，實(shí)驗(yàn)組，年齡2歲~13.3歲）。兩組病人由小兒泌尿外科主治以上資歷的醫(yī)師進(jìn)行診斷，都排除了尿道下裂、尿道上裂、小陰莖或蹼狀陰莖。對(duì)兩組個(gè)體術(shù)前的陰莖體的顯露長度和陰莖實(shí)際長度分別進(jìn)行測(cè)量，數(shù)據(jù)換算得到陰莖指數(shù)（Penis Index,PI）。 結(jié)果： A組患兒PI范圍在0~0.760之間，平均為0.386。B組患兒PI范圍在0.487~1.0之間，平均為0.852，兩組平均數(shù)經(jīng)過t檢驗(yàn)，得到p接近于0，即P0.001，統(tǒng)計(jì)學(xué)上差異具有非常顯著意義。 結(jié)論： 經(jīng)過對(duì)陰莖測(cè)量后獲得的陰莖指數(shù)的分析比較，得出隱匿陰莖患兒的平均指數(shù)（以下簡(jiǎn)稱PI值）顯著小于包莖患兒的PI值（P≤0.001）。基于以上分析，我們推測(cè)PI=0.5可以作為一個(gè)診斷臨界值，即：PI≥0.5診斷為包莖，反之PI＜0.5診斷為隱匿陰莖。
[Abstract]:Background: underexposure of the penis in children is a group of diseases in which the penis cannot or is not fully exposed. At present, the diagnosis and evaluation of the disease mainly depend on the subjective judgment of the doctor and lack of objective indicators. The purpose of this study was to explore an objective criterion based on statistical data to evaluate the clinical diagnosis and efficacy of concealed penis. Materials and methods: from June 2012 to March 2013, 55 cases (group B, control group, aged 2.5 ~ 14 years) underwent circumcision of phimosis and 58 cases (group A) of concealed penis in hospital undergoing penile plastic surgery. Experimental group, aged from 2 to 13.3). Both groups were diagnosed by a pediatric urologist or above who ruled out hypospadias, small penises or webbed penises. The exposure length of penile body and the actual length of penis were measured before operation in two groups. The penile index (Penis Index,PI) was obtained by data conversion. Results: the range of PI in group A was between 0 and 0.760, and that in group B was 0.386.B, the range of PI was between 0.487U and 1.0, and the average was 0.852.The average value of the two groups was obtained by t test, p being close to 0, that is, P 0.001. The statistical difference is very significant. Conclusion: the average index (PI) of the children with concealed penis was significantly lower than that of the children with phimosis (P 鈮
