CRBD is related to different degrees of irritation caused by the volume of the balloon in the urinary catheter, and when CRBD occurs, it may cause severe postoperative pain and trauma by self-removal of the catheter, further leading complications. Although many drugs can improve CRBD, measures that can be immediately intervened by non-nursing staff at any time and even have different side effects on patients due to drug use.Therefore, the author wants to use this study to explore the reduction of catheter balloon volume can effectively reduce the degree of CRBD, is a non-invasive and immediately executable nursing treatment.the quality of clinical care and hospitalization of the patient can be further improved, reducing the patient's inappropriate, thereby improving the quality of medical care.

Catheter-Related Bladder Discomfort (CRBD) has been attached importance in recent years. Reducing the discomfort of patients with effective treatment is a part of our medical and nursing care that needs to be paid more attention to. The literature has pointed out that CRBD is related to different degrees of irritation caused by the volume of the balloon in the urinary catheter, and when CRBD occurs, it may cause severe postoperative pain and trauma by self-removal of the catheter, further leading to urethral injury and subsequent urethral stricture, and complications such as bleeding, surgical wound dehiscence, and arrhythmia. Although many drugs can improve CRBD, measures that can be immediately intervened by non-nursing staff at any time and even have different side effects on patients due to drug use.

In the past 20 years, only one piece of literature has discussed the effect of catheter balloon volume on CRBD, and the sample size is relatively small and even not related to the Asian region. Therefore, the author wants to use this study to explore the reduction of catheter balloon volume can effectively reduce the degree of CRBD, the investigators will collect in different procedure(stone procedure, herniarraphy, nephrectomy), and the investigators used different urinary catheter balloon size(10ml and 5ml), tp investigate the patient with the severity of catheter-related bladder discomfort.In addition to reducing the side effects of patients due to drug use, is a non-invasive and immediately executable nursing treatment.

Further, if post-evidence nursing intervention can effectively reduce the CRBD generated, thereby increasing the patient's comfort, and allowing the patient to cooperate more with the treatment to achieve an effective therapeutic effect, thereby improving the quality of care and the enlargement of recovery.

Eventually, the quality of clinical care and hospitalization of the patient can be further improved, reducing the patient's inappropriate, thereby improving the quality of medical care.
