Objective To manage double-J ureteral stent placed in urology patients and to prevent complications. Methods A total of 3,260 patients were chronologically assigned to a control group (n=986) and an intervention group (n=2,274). The control group used paper-based health records that the information about double-J stent was written by the surgeon after surgery, while the intervention group used electronic-based health records that an embedded warning system was designed and integrated into the hospital information system for double-J stent information recording. Nurses followed up patients in both groups and reminded them return to the hospital for management of double-J stent in time. Results Surgeon spent less time on recording in the intervention group compared with the control group (P<0.05). The incidence rates of delayed management of double-J stent and complications except stent dislodgement were significantly lower in the intervention group than those in the control group (all P＜0.05）. Conclusion The application of warning system for the indwelling double-J ureteral stent can help medical staff to enhance work efficiency and reduce complications.
