ABSTRACT
Renal function, the anatomic and functional status of the vena cava inferior, renal arteries and veins, and spermatic veins were evaluated in healthy individuals and patients with varicocele before and 12 months after laparoscopic ligation of the left spermatic vein. The renal vessels were assessed by color Doppler ultrasonography and renal function was examined by complex radionuclide study with 99mTc-pentatech. There were no significant changes in the diameter of renal arteries and vena cava inferior and the right arterial blood flow velocities in healthy individuals and patients. No difference were found in the diameter of renal veins and in the blood flow velocity in renal arteries and veins. The enlarged renal veins and decreased mean blood flow velocity in the left renal vein in healthy persons and patients with varicocele and lower blood flow in the left renal artery than in the right one indicate left-sided renal hypertension that is attributable to left renal vein overload due to a great variety of collaterals and to compression at the site of "a forcepts". At the same time 12-month postoperative ultrasonic, Doppler and complex radionuclide studies revealed no significant changes in the diameter and blood flow velocity in the left renal vein.

The paper reports 5 cases of rare renal disease, multilocular cyst. Pathogenetic, pathomorphological, clinical and visual diagnostic aspects of the cyst presented in the literature are reviewed. Special emphasis is placed on diagnostic potential of ultrasound investigation. Current values of computed tomography and conventional X-ray urological techniques, difficulties in differential diagnosis of multilocular cyst with other cysts and renal carcinoma are shown. The authors think it valid to use combined radiological methods in determination of pathological process origin and its details, calcificates, in particular.
