A suprapubic catheter is a medical device used to drain urine from the bladder. It is inserted through the abdominal wall, just above the pubic bone, and is typically used when a patient cannot use a regular urethral catheter due to blockages, injuries, or other medical conditions. This type of catheter is often preferred for long-term use because it can reduce the risk of urinary tract infections and is generally more comfortable for the patient. Regular care and maintenance are essential to prevent complications and ensure proper function of the suprapubic catheter.
