Excretion of urinary enzymes after extracorporeal shock wave lithotripsy: a critical reevaluation.
The excretion of the urinary enzymes alanine aminopeptidase, alkaline phosphatase, gamma-glutamyl-transferase and N-acetyl-beta-D-glucosaminidase, and the 99mtechnetium-diethylenetriaminepentaacetic acid isotope clearance were studied in 35 patients treated with extracorporeal shock wave lithotripsy (ESWL*). Enzyme measurements were made before and consecutively on days 1, 2 and 5, and at 3 months after treatment. A control group investigated at the same intervals was included. Posttreatment enzyme values were not significantly different from those before treatment except for alkaline phosphatase on day 1 after ESWL. Some individuals had short-term increases of enzymuria that were greater than biological variations in the control group. The transient changes of enzymuria after ESWL had no predictive value for kidney function, since no decreased renal function was observed in individual patients with high enzyme excretions after ESWL.
