Emergency percutaneous nephrostomy in the septic kidney.

From 250 upper tract obstructive uropathy cases we have studied 64 patients hospitalized with toxico-septic shock. The constant symptom was arterial hypotension. Other 3 patients with long-standing urinary infection due to lithiasis developed this dreaded complication after PNL (staghorn stones-2, pyelic stone-1). In complicated obstructive uropathy cases associated with toxico-septic shock, percutaneous nephrostomy for high urinary derivation in emergency is usually made under local anaesthesia. Its aim is rapid and efficient clearance of kidney obstruction, with minimal damage for the patient; then it is followed by strong antibiotherapy associated with other reanimation and intensive care measures. There were 11 deaths. The stone generating obstructive uropathy was removed subsequently, after the improvement of biological constants and general state of the patient, under the protection of percutaneous nephrostomy.
