[Sonographic findings in analgesic nephropathy].
Demonstration of circular papillary calcifications in renal sonography, frequently combined with urinary retention and reduction of kidney size, can be used as evidence of analgesic nephropathy. This previously not described sonomorphologic pattern was observed in 8 out of 10 patients on dialysis treatment with previously known abuse of analgesics and in 5 out of 8 patients with compensated reduction of renal function and established abuse of analgesics. In addition, this sonographic pattern was also reported in 6 patients with increased serum creatinine concentration of unknown origin. This resulted in detection of a previously unknown abuse of analgesics.
