[Renal ultrasound. Urologic and nephrologic viewpoint].

Renal ultrasound examination is an integral part of urologic and nephrologic clinical examination. It brings very useful information about kidney morphology (B-mode) and haemoperfusion (renal color coded duplex ultrasonography). Standard examination technique is required for recognition of normal findings, urinary transport disturbances of diverse causes (stones, intrinsic or extrinsic compression), kidney tumours and kidney injury. Typical ultrasound findings of these abnormalities were demonstrated. Renal ultrasound with new techniques (sono-CT, harmonic tissue imaging, power mode etc.) is for urology and nephrology an indispensable diagnostic method. In combination with patient history, clinical and laboratory examination takes important part in accomplishing the diagnosis.
