[Renal lesions in patients with chronic lymphocytic leukemia].

32 patients with chronic lymphoid leukemia (CLL) were examined to specify reasons of renal damage. Measurements were made of blood urea, creatinine, total protein, electrolytes, uric acid. Also, urinary sediment, diurnal loss of protein and creatinine with urine, glomerular filtration rate, concentration ability of the kidneys were studied. Urinary system was assessed by ultrasound. Most CLL patients studied had renal affection characteristic for chronic pyelonephritis with chronic renal insufficiency. The ultrasonic investigation stated reduced size of the kidneys, thinning of the cortex, extension of the renal pelvis and calyces, concrements. The kidneys and ureters were pressed and displaced by enlarged spleen, liver, lymph nodes. The plan of CLL patients' examination must include ultrasonic investigation of the abdominal organs for early detection of renal lesions.
