Abstract: This study was conducted in a clinical setting of a regional hospital. This research aimed to evaluate a non-invasive clinical diagnostic tool to monitor urinary bladder function by ultrasound measurement of residual urine before, and after bladder training among hysterectomy women. To correlate the voiding urine volumes derived from ultrasound measurement and that measured upon micturition. 62 hysterectomy patients were recruited for the study. Bladder function was evaluated by ultrasound measurement before and after surgery. In simple hysterectomy group, there was improved bladder function upon discharge with 1.14 days. Data was analyzed to evaluate the correlation between urine volume derived from ultrasound measurement and the micturited urine volume (r=0.945, p<0.001). The percentage of retained urine volume scanned with ultrasound was 22% (pre-operation), 16.2% (post trained) and 10.6% (discharge). One way ANOVA showed there was a significant difference of the percentage of retained urine volume at different hospitalization times (F=3.64, df=2, p=0.028). Post-hoc Tukey LSD results showed the percentage of retained urine volume upon discharge was significantly lower than before operation (p=0.021). In radical hysterectomy group, there was longer duration of bladder training up to 12.8 days. A high correlation between urine volume derived from ultrasound measurement and the micturited volume was found (r=0.964, p<0.001). There found residual urine increased from 7.71% (pre operation), to 41.37% (bladder training) and decrease to 13.84% (discharge) of mean retain/total scan volume after bladder training. There was a significant difference of the percentage of retained urine volume at different hospitalization time (F=18.89, df=2, p<0.001). Early ultrasound scanning performed and clinical palpation could aid to have early diagnosis of urinary retention and provided clinical guidance for bladder training. Present study established an effective clinical assessment role of ultrasound scanning in bladder training among hysterectomy patients during rehabilitation period.
