Abstract
Analgesic nephropathy can present as an obstructive uropathy by ureteric impaction of a sloughed renal papilla. Five out of 12 patients admitted with analgesic nephropathy presented with obstructive renal failure. Endoscopic surgery to deal with the obstruction was successful in every case. Removal of the necrotic renal papilla with a Dormia ureteric stone basket was performed six times whilst ureteric catheterization was sufficient to restore urine flow on two occasions. Two of the 5 patients had had a previous nephrectomy for obstructive pyelonephritis. These results suggest that endoscopic surgery is safe and effective in the treatment of acute obstructive renal papillary necrosis.
