What medical reason to stop inserting a indwelling catheter?

An indwelling catheter should be stopped if there is evidence of a urinary tract infection (UTI), as continuing use can exacerbate the infection and lead to further complications. Additionally, if there are signs of urethral injury or severe discomfort in the patient, catheterization should be halted. Other reasons include the patient's recovery of normal urination, potential allergic reactions to the catheter material, or the presence of blood in the urine indicating possible trauma.
