Urinary catheterization is a medical procedure that involves inserting a catheter—a thin, flexible tube—into the bladder through the urethra to drain urine. This is typically performed when a patient is unable to urinate naturally due to conditions like urinary retention, incontinence, or following certain surgeries. The catheter may be indwelling (left in place) or used intermittently, depending on the patient's needs. Proper technique and hygiene are crucial to minimize the risk of urinary tract infections.
