Introduction
Under normal circumstances, a urinary catheter should be left in place for 1 day after surgery, 7 days in cases of urinary retention, and 14 days if there is a urethral disease. Patients are advised to follow medical instructions for symptomatic treatment. Specific analysis is as follows: The most common scenario is undergoing general anesthesia, which affects the patient's normal urination function, thus requiring urinary catheterization, typically for about 1 day.

Under normal circumstances, it is appropriate to leave a urinary catheter in place for 1–14 days, with the specific duration depending on the type of catheter used. For surgical procedures, a catheter is typically left in place for 1–3 days; for urinary retention, around 7 days is appropriate; and for patients with urethral diseases, up to 14 days may be necessary. Patients are advised to follow medical instructions and receive treatment according to their specific condition. Detailed analysis is as follows:

In surgical procedures, a urinary catheter is placed to facilitate monitoring of urine output during and after surgery, and to prevent urine retention from interfering with surgical operations or postoperative recovery. Generally, the catheter remains in place for 1–3 days after surgery. Once the patient regains consciousness from anesthesia and bodily functions begin to recover sufficiently to allow voluntary urination, the catheter can be considered for removal. In cases of acute urinary retention caused by conditions such as benign prostatic hyperplasia or urethral stricture, urgent catheterization is required to drain urine and relieve excessive bladder distension. After approximately 7 days of observation, as the patient's urination function gradually returns to normal, the catheter can be removed.

For patients with urethral diseases, the duration of catheterization may be longer, usually around 14 days. Intermittent catheterization is often used—urination is assisted at regular intervals based on factors such as residual urine volume, rather than maintaining continuous catheter placement. Healthcare providers must closely monitor for potential complications such as urinary tract infections and implement appropriate care measures, including regular replacement of the catheter and urine collection bag, and bladder irrigation when necessary, to minimize harm from complications.

The duration of urinary catheterization should be determined comprehensively based on the patient’s specific condition and recovery progress, aiming to ensure therapeutic effectiveness while minimizing the risk of complications.
