The differentiation of renal from bladder bacteriuria is difficult on clinical grounds alone. To evaluate the correlation between site of infection and urinary beta-glucuronidase activity, 46 patients with well documented recurrent bacteriuria were studied by bilateral ureteral catheterization. Urinary beta-glucuronidase activity was also determined in 46 control subjects. In general, asymptomatic patients with renal bacteriuria, either unilateral or bilateral, had levels of enzyme activity in their urine comparable to patients with infection confined to the bladder and to normals. Only 4 of 25 patients with renal bacteriuria had significant elevations of urinary beta-glucuronidase. After localization of infection, 9 of 10 patients treated with kanamycin, a potentially nephrotoxic drug, developed significant elevations of urinary beta-glucuronidase. The results of these studies indicate that determination of beta-glucuronidase activity in urine is not useful in predicting the site of infection in patients with bacteriuria but may find a role in screening for early nephrotoxicity.

The aim of the paper was to study the urinary beta-glucuronidase activity in 30 patients with renal cell carcinoma (RCC), histopathologically proven after surgery, and 32 healthy subjects taken as controls. Classification of patients was done using the TNM system. A statistically significant increase (p < 0.01) in this enzyme was found in RCC patients, without relation to the changes in the urinary sediment (hematuria, pyuria, bacteriuria) or tumor dissemination. Urinary beta-glucuronidase is a useful marker in the diagnosis of malignant renal tumors.
