suprapubic catheterization

suprapubic catheterization

An emergency procedure offering immediate relief to a patient with a full bladder and total obstruction to urinary outflow. Under local anaesthesia a TROCAR and surrounding CANNULA are passed directly through the abdominal wall in the mid line at a point about one third of the distance from the pubis to the navel. The cannula is pushed into the bladder and the trocar removed to that urine can flow out. In children an intravenous cannula can be used.
