Occurrence of pyuria and bacteriuria in asymptomatic hemodialysis patients.
Patients with end-stage renal disease on hemodialysis have documented defects in their immune responses, and infections contribute significantly to their morbidity and mortality. This study prospectively detected and quantitated leukocyturia and bacteriuria in asymptomatic hemodialysis patients. Thirty-one percent of asymptomatic hemodialysis patients had significant pyuria (> 10 white blood cells per high-power field) and 25% had bacteriuria of pathologic dimensions, (> 1 x 10(5)/mL of a single microorganism). Pyuria was a good marker for significant bacteriuria in these patients. These results demonstrate that the urinary tract, even in ESRD patients on hemodialysis, may represent a significant reservoir for infection.
