Objective: To explore the application of urodynamic monitoring instrument in indwelling catheterization in severe patients, aiming at early detection and prevention of acute kidney injury, providing a new method of bladder exercise, and reducing the occurrence of catheter-related complications. Methods select intensive medicine of zhejiang province peoples hospital in January 2021 - December 2021 patients expected to more than 7 days, placing a urinary catheter to group by random number table method, the timing of the control group were treated by routine urine mode, experimental group were treated by dynamic monitor urine flow monitoring mode, three days later by the open mode to the constant voltage mode to train regularly, The results were analyzed. Results The bladder volume of the experimental group was 427.31±46.34 mL, and that of the control group was 400.24±39.01 ml, the difference between the two groups was statistically significant (P<0.05). There was no significant difference in the incidence of catheter-related infection between experimental group 10/102(10%) and control group 12/98(12%) (P>0.05). The mean intra-abdominal pressure was 7.24±3.18mmHg. Five patients were predicted to have acute kidney injury. Conclusion Urodynamic monitoring during indwelling catheterization in severe patients can predict acute kidney injury, increase bladder safety capacity and exercise bladder function.
