nephrostomy

This requires drainage, best performed by nephrostomy.

A nephrostomy is created when the flow of urine is diverted directly from the kidneys to the abdominal wall.

First planned nephrostomy.

They popularized nephrostomy drainage, percutaneous stone extraction, and urethral stenting.

Percutaneous nephrostomy .

Percutaneous nephrostomy or ureteral stent placement may be indicated to relieve obstruction caused by a stone.

Acute obstruction of the upper urinary tract is usually treated by the insertion of a nephrostomy tube.

More recently, flexible ureteroscopy has been adapted to facilitate retrograde nephrostomy creation for percutaneous nephrolithotomy.

The most common cause of blockage necessitating a nephrostomy is cancer, especially ovarian cancer and colon cancer.

A nephrostomy is performed whenever a blockage keeps urine from passing from the kidneys, through the ureter and into the urinary bladder.

If the cause is obstruction of the urinary tract, relief of the obstruction (with a nephrostomy or urinary catheter) may be necessary.

Percutaneous nephrostomy is an interventional radiology/surgical procedure in which the renal pelvis is punctured whilst using imaging as guidance.

A comparative analysis of nephrostomy, JJ stent and urgent in situ extracorporeal shock wave lithotripsy for obstructing ureteric stones.

A nephrostomy is an artificial opening created between the kidney and the skin which allows for the urinary diversion directly from the upper part of the urinary system (renal pelvis).

Pyelonephritis requires antibiotic therapy, and sometimes surgical intervention such as ureteroscopy, percutaneous nephrostomy or percutaneous nephrolithotomy, as well as treatment of any underlying causes to prevent its recurrence.

Vascular access devices (VAD) and other artificial indwelling devices (i.e., percutaneous nephrostomy tubes, biliary drainage tubes, gastrostomy or jejunostomy tubes) are other commonly implicated sources of infection.

Chemolysis is usually achieved through the use of oral medications, although in some cases, intravenous agents or even instillation of certain irrigating agents directly onto the stone can be performed, using antegrade nephrostomy or retrograde ureteral catheters.
