title: [Extracorporeal lithotripsy by shock waves: results in 185 patients].
abstract: Extracorporeal shock wave lithotripsy has become the treatment of choice of nephrolithiasis with surgical indication. Our unit is managing urinary tract stones using the Sonolith 3000 lithotritor since April 1991. The procedure is performed in ambulatory patients and requires analgesia and mild sedation. We report the experience in the treatment of the first 185 patients. In 87% of them, the stones disappeared completely, 8.7% of patients were left with residual fragments without indication of further treatments and in 4.3% the procedure failed. There was no mortality. In 13 occasions, obstructive complications at the distal ureter were produced by the stone fragments that required ureteroscopy in only three patients and 11 patients had severe renal colic. We conclude that this procedure is safe and effective in the treatment of urinary tract stones.
