There were 12 patients, with CIC bladder management strategy, recruited as the subjects of the research under the specification of the Institutional Review Board (IRB): 10510-003 of Chi Mei Medical Center. Table 3 is recognized as an overview of their demographic and clinical features. The age of patients ranged from 21 to 51 years old with an average of 39.25 years old. The recruited patients were interpreted by clinicians and their cytometric capacity, intravesical pressure and compliance were in the normal range, and their bladder pressure was highly correlated with the volume [4; 24; 32]. Level of injury primarily fell on C (58.4%) and T (33.3%). The majority of these patients chose to conduct CIC indoors (91.7%) and 33.3% of them kept a record of each voided volume, while 66.7% were in fear of excess voided volume. This study observed that only 25% of the patients returned for OPD follow-up after one year or more. CIC assistant system automatically records and uploads the precise amount of catheterization and statistics, as shown in Figure 5. Figure 6 shows the regressive curve of urine volume measurement between CIC assistant device and graduated cylinder, its R-square was 0.99. Records are displayed on the app on the client's screen. After collection and calculation, the feedback system reminds patients to modify their lifestyles or to return to the hospital for further inspection in order to reduce UTIs and other complications. Furthermore, the accessible luxatory function shows the shortest route to the most suitable luxatory after patients enter their requirements. This saves considerable time for patients when searching for a toilet. Table 4 represents the frequency in a month for voided urine volume \(>\)550 mL of 12 patients with CIC strategy. Fewer SCI patients with bladder sensations encountered even more problems of excess voided volume in comparison with those without bladder sensations. \begin{table}

Table 3: Demographic and clinical features (\(n=12\)). Figure 7 shows how the accessible lavatory function in the app provided information regarding all the nearby accessible lavatories with a filter function. Patients could also add a new lavatory on our cloud system after verification. The results of patients looking for a lavatory in an unfamiliar environment with this function were shown by the following data: unfamiliar 43.1%, semi-familiar 27.2%, and familiar 17.6%. The time spent searching for a lavatory independently was 22.5 min, 15.8 min, and 13.6 min respectively. By using the accessible lavatory function, the arrival time decreased

SCI patients with CIC were inclined to perform CIC at home, or at least indoors, because of the inconvenience of searching for an accessible lavatory in an open area (Table 3). A reduced motivation for going out could lead to social detachment, psychological disorders, and an unpleasant lifestyle [19].
