Retrospective comparison of complex cystic renal lesions which are found with computed tomography (CT) and were controlled with contrast enhanced ultrasound (CEUS).
All subjects receive an contrast enhanced CT due to different clinical indications. When a complex cystic renal lesion is found an evaluation with CEUS is performed. The CEUS protocol included a native baseline examination of both kidneys. After a bolus injection of 1.5 ml SonoVue (Bracco, Milano, Italy) an examination of the affected kidneys is performed over a time period of at least three minutes. An optional dose will be given when the initial examination is not conclusive, e. g. when the arterial phase is partly missed. When both examinations are done the lesions were classified using the Bosniak classification system and a comparison of both methods will be done.

Kidney Neoplasms
Tumors or cancers of the KIDNEY.
Kidney Papillary Necrosis
A complication of kidney diseases characterized by cell death involving KIDNEY PAPILLA in the KIDNEY MEDULLA. Damages to this area may hinder the kidney to concentrate urine resulting in POLYURIA. Sloughed off necrotic tissue may block KIDNEY PELVIS or URETER. Necrosis of multiple renal papillae can lead to KIDNEY FAILURE.
Kidney Cortex
The outer zone of the KIDNEY, beneath the capsule, consisting of KIDNEY GLOMERULUS; KIDNEY TUBULES, DISTAL; and KIDNEY TUBULES, PROXIMAL.
Kidney Tubules
Long convoluted tubules in the nephrons. They collect filtrate from blood passing through the KIDNEY GLOMERULUS and process this filtrate into URINE. Each renal tubule consists of a BOWMAN CAPSULE; PROXIMAL KIDNEY TUBULE; LOOP OF HENLE; DISTAL KIDNEY TUBULE; and KIDNEY COLLECTING DUCT leading to the central cavity of the kidney (KIDNEY PELVIS) that connects to the URETER.
Neoplasms By Site
A collective term for precoordinated organ/neoplasm headings locating neoplasms by organ, as BRAIN NEOPLASMS; DUODENAL NEOPLASMS; LIVER NEOPLASMS; etc.
