“…Reduced renal blood flow and glomerular filtration rate manifest in a CT image as weaker enhancement of the renal parenchyma ( 8 , 9 ) . Obstruction of urine outflow results in weaker contrast enhancement of the kidney and delayed contrast agent passage into the urine (without the possibility of precise quantification) ( 3 , 9 ) . Renal artery stenosis also results in a reduced enhancement of the renal parenchyma, with the difference that in the arterial phase it is usually possible to quantify the degree of stenosis, and in the excretory phase there is a discernible passage of the contrast agent into the urine (without a possibility of accurate quantification).…”

“…Contrast-enhanced ultrasonography is a recognized method for the assessment of kidney lesions and perfusion disorders resulting from impaired patency of the renal vessels (2)(3)(4)(10)(11)(12) . Modern ultrasonography contrast agents persist in the vessels, without interstitial diffusion and glomerular filtration.…”

“…Kidney enhancement curves represent the influx peak followed by successive waves of recirculation. During the examination, only one kidney is imaged, which makes it difficult to compare the degree of enhancement of one in weaker contrast enhancement of the kidney and delayed contrast agent passage into the urine (without the possibility of precise quantification) (3,9) .

Aim: The study aimed to evaluate the usefulness of contrast-enhanced ultrasonography in renal perfusion disorders caused by obstructive uropathy. Case description: We present a case of a patient with a horseshoe kidney, in which the urine outflow from the right part of the kidney was blocked due to the presence of a bladder tumour infiltrating the ureter. Perfusion disorders in both parts of the kidney, visible in computed tomography, were partially reflected in the ultrasound image. Conclusions: Doppler ultrasound and contrast-enhanced ultrasound may be useful for monitoring perfusion disorders in the course of obstructive uropathy, provided that appropriate methodology is developed to compare blood flow in both kidneys.

Urothelial tumours are the fourth most common cancer in the world and account for the majority of tumours involving the bladder. The symptom that often leads to diagnosis is the presence of haematuria. Diagnosis is made by cystoscopy, which is currently the gold standard in bladder cancer. Computed tomography (CT) performed with pre- and post-contrastographic phases is essential in order to assess the loco-regional and distant extension of disease. The diagnosis and staging of upper tract urothelial cancer (UTUC) are best done with computed tomography urography and flexible ureteroscopy (URS). In the acquisition protocol of this type of tumour, a urographic phase is mandatory, which allows for an accurate diagnostic assessment of the renal pelvis, ureter and bladder, especially in papillary forms. The use of multiple acquisition phases, especially in this type of patient who will have to perform follow-up CTs, leads to the problem of overexposure to ionising radiation, as well as the frequent administration of iodinated contrast medium. For this reason, in recent year, the focus has been put on advanced technologies such as dual-energy CT (DECT), that is a method that can offer some advantages for both radiologist and patient, in the diagnosis of cancer and, in particular, urinary tract disease.
