ABSTRACT
Objective:To investigate the effect of optimized catheter clipping training and automatic balloon retraction ureteral catheter removal on first urination of patients after neurosurgery, and provide guidance for postoperative micturition of these patients.Methods:From August 2020 to August 2021, 208 patients admitted to Department of Neurosurgery, the Affiliated Hospital of Xuzhou Medical University, undergoing craniocerebral surgery under general anesthesia and indurating catheter were selected as the study subjects by convenient sampling. They were divided into control group ( n=69), observation group A ( n=69) and observation group B( n=70) by random number table method. The control group received routine catheter clipping training and routine ureteral catheter removal, the observation group A received optimized catheter clipping training and routine ureteral catheter removal, and the observation group B received optimized catheter clipping training and automatic balloon retraction ureteral catheter removal. The first micturition time, first micturition volume, micturition circumstance, pain score and urethral irritation sign of the three groups were observed and compared. Results:The first urination time in observation group A and B were (11.58 ± 6.59) min and (10.06 ± 5.91) min, respectively, lower than (37.14 ± 13.74) min in control group, and the difference was statistically significant ( t=13.94, 15.07, both P<0.05); there was no significant difference between observation group B and observation group A ( P>0.05). The first urine volume were (303.66 ± 43.74) ml in control group, (299.06 ± 41.26) ml in observation group A and (299.28 ± 43.17) ml in observation group B, and the difference was not statistically significant ( P>0.05). The incidence of urination (spontaneous urination, induced urination and urinary retention) in observation group A was better than control group ( χ2=16.47), while observation group B was better than observation group A and control group ( χ2=8.59, 37.83), the differences were statistically significant (all P<0.05). There was no significant difference in pain score of ureteral catheter removal between observation group A (2.71 ± 0.67) and control group (2.87 ± 0.78) ( P>0.05). The score of observation group B (1.41 ± 0.65) was lower than that of control group and observation group A, the differences were statistically significant ( t=11.93, 11.62, both P<0.05). There was no significant difference of the incidence of urethral irritation (grade 0, 1, 2, and 3) between observation group A and control group ( P>0.05). Observation group B was lower than control group and observation group A, the differences were statistically significant ( t=38.81, 25.27, both P<0.05). Conclusions:Optimized catheter clipping training and automatic balloon retraction ureteral catheter removal can effectively shorten the first urination time of patients after neurosurgery, reduce the pain of ureteral catheter removal and urethral irritation during the first urination, improve the success rate of the first urination, and effectively prevent the occurrence of urinary retention.
