Abscess (sometimes referred to as a pus collection) is a cavity filled with pus and surrounded by the membrane of inflammatory tissue. Depending on its size and localization, it can be treated conservatively by antibiotics, by surgical excision or by insertion of drainage tube. Percutaneous tube placement is minimally invasive procedure, which results in shorter hospital stay and faster recovery period. As such, in well-considered cases it is advantageous compared to surgery.
CORE BIOPSY means removing a piece of living tissue from an organ or other part of the body using a bigger spring loaded needle. It is usually performed by a radiologist but may sometimes involve a team consisting of a radiologist, surgeon and pathologist.
Sometimes the aspiration is performed to remove the fluid around the lung or from the abdomen in order to relieve the pressure. In that case it can be both diagnostic and therapeutic.
Ureteric stent is a plastic tube that restores the urine flow from the kidney to urinary bladder through the blocked ureter. Like nephrostomy, it will relieve the pressure in the kidney and prevent its damage. The common cause for the blockage is stone and rarely scar or tumor. The procedure is performed either by the urologist through the bladder, or by the radiologist through the kidney.
Biliary drainage means placement of the soft plastic tube into the liver biliary ducts that are blocked usually by the stone or tumor. The purpose is to release pressure within the liver and avoid its damage as well as to prevent backflow of bile into the blood and consequent damage of the brain and other organs. The tube will allow the bile to pass around the blockage or to drain outside the body into the collection bag.
Nephrostomy means placement of the soft plastic tube into the kidney which is blocked. The purpose is to release pressure within the kidney and prevent its destruction. It is sometimes performed to divert urine flow from the injured ureter and allow healing process.
