Endotoxemia and bacteremia in patients following ultrasonic lithotripsy

Summary The incidence of endotoxemia was studied in 17 patients who underwent ultrasonic lithotripsy (USL), and compared with the incidence in 11 patients who underwent transurethral resection (TUR) and in 8 patients who underwent other operations. Fourteen of 17 patients (82%) who underwent ultrasonic lithotripsy had endotoxemia. The incidence of endotoxemia after USL was significantly higher than that after TUR (9%) or after other operations (12.5%). Only 2 of the 17 patients (12%) who underwent USL had bacteremia. The organisms isolated were P. mirabilis and S. sanguis, respectively. Six of the 14 patients with endotoxemia after USL suffered high fever. These data suggest that endotoxemia is a factor which causes high fever after USL.
