Patients were segregated to one of two groups, depending on management of AUR (in\u2010and\u2010out catheterization at one time: Group 1 or indwelling catheter: Group 2). To characterize the optimal patient characteristics particularly fitting for Group 1 among each success subgroup, Fisher's linear discriminant analysis (LDA) was then conducted. Using an equation from LDA, the hit ratio was evaluated in a prospective trial from July to December 2009.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>TWOC success rate was 25.1% for Group 1 and 30.3% for Group 2. In successful cases, age, retention volume, and prostate sizes were significantly lower than those of failure counterparts in both Groups 1 and 2. Among these, age and retention volume were finally selected for LDA. When comparing successful cases, these two were significantly lower in Group 1 than Group 2. LDA showed an 81.6% hit ratio for cases with successful TWOC. In a prospective trial of 28 patients, using an equation from LDA, five of seven patients in Group 1 (71.4%) and 16 of 21 patients (76.2%) in Group 2 succeeded in their initial TWOC.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>These results suggest the efficacy of in\u2010and\u2010out catheterization as a way of attempting TWOC, particularly for the patient with relatively low retention volume and younger age.
