Urethral catheterization is a medical procedure that involves inserting a thin tube, called a catheter, into the urethra to drain urine from the bladder. This procedure is often performed when a patient is unable to urinate naturally due to various medical conditions, surgeries, or injuries. The catheter can be left in place for a short or long duration, depending on the patient's needs. It is important to maintain proper hygiene during the procedure to reduce the risk of urinary tract infections (UTIs) and other complications. Regular monitoring is also essential to ensure the catheter is functioning correctly.
