The purpose of this study is to establish a predictive factors which are associated with stress urinary incontinence (SUI) due to intrinsic sphincter scarcity (ISD) in women.Between Jan 2008 as well as December 2009, 185 women with urodynamically proven SUI were included in this study as well as retrospectively reviewed a medical record. Preoperative SUI symptoms were classified by Stamey grade. Valsalva leak indicate pressure (VLPP) determination array was repeated two times in each subject after finishing one array of VLPP measurement. The patients were classified into three groups according to VLPP; 1) ISD: VLPP60 cm H(2)O, 2) equivocal: 60<VLPP90 cm H(2)O, 3) anatomical incontinence (AI): VLPP>90 cm H(2)O. Chi-square exam as well as multivariate (logistic retrogression test) analyses were performed to establish a factors associated with ISD.The mean patient age was 54.2 years (range, 44.5 to 68.4 years). Seventy-one women (38.3%) were in a ISD group as well as 70 (37.8%) in a AI group. The results of univariate as well as multivariate analyses found which women with ISD had a higher symptom class than women with AI (P=0.001 as well as 0.0001, respectively). The series of patients in a ISD as well as AI group in accordance with a symptom class were 7 (10%) as well as 44 (62%) in class I, 50 (54%) as well as 23 (25%) in class II, as well as fourteen (63%) as well as 3 (14%) in class III respectively. There was no association between VLPP as well as other clinical factors.High symptom class was a usually independent clinical factor which predicted a participation of ISD. This should be considered when conversing a patients with SUI.
