Clinical trials: Ureteral Stent
Kidney Disease
A Prospective Comparison Between Ureteral Stent and Nephrostomy Tube for an Urgent Drainage of Obstructed Kidney
Kidney obstruction might be caused by a stone in the urinary tract. In case of accompanying fever or renal failure, an urgent drainage might be needed. This can be done either by placing an ureteral stent or a nephrotomy tube.
