Catheter Placement for Dialysis or Urinary Drainage

Catheter placement is a minor medical procedure used to allow dialysis access or urinary drainage when normal pathways are not adequate. For dialysis, a catheter is placed into a large vein to enable blood flow during treatment. For urinary drainage, a catheter is inserted into the bladder to drain urine safely. The procedure is usually performed under sterile conditions with local anesthesia. Catheter placement helps relieve symptoms, prevents complications, and supports effective treatment and patient comfort.
