TRANSITIONAL CELL TUMORS OF THE RENAL PELVIS IN ANALGESIC ABUSERS (Reprinted from Scandinavian Journal of Urology and Nephrology, vol 2, pgs 145-150, 1968)

摘要

In a clinical series of 242 patients with chronic non-obstructive pyelonephritis, 142 patients were classed as chronic abusers of drugs containing phenacetin. Seventy-nine per cent of all the patients were followed up for one to eleven years (average 5.3 years). Eight patients (about 8 per cent) in the group of analgesic abusers developed transitional cell tumors of the renal pelvis, but no such tumors arose in the non-abusers.
