title: [A "small" kidney tumor].
abstract: The authors think it necessary to distinguish small tumors of the kidney--a neoplasm 4 cm in size maximum. The number of such small tumors account for 1/3 of all renal newgrowths. An important role in detection of small tumors belongs to ultrasonography. Ultrasonic finding of the tumor should be followed by spiral computer tomography with 3-dimensional reconstruction of the image of the tumor, calyceal-pelvic system and renal vessels. Small tumors are asymptomatic in 71.4 cases, in many cases benign, in renal cell carcinoma their cells are well differentiated, they do not invade paranephral fat. Morphological verification is effective and safe in puncture biopsy of the tumor under ultrasound control. Adequate treatment depends on correct diagnosis of the tumor nature. Surgery of choice in small tumor of the kidney is resection.
