  2. Renal cyst - Wikipedia

    en.wikipedia.org/wiki/Renal_cyst

    Simple renal cyst. A renal cyst is a fluid collection in or on the kidney. There are several types based on the Bosniak classification. The majority are benign, simple cysts that can be monitored and not intervened upon. However, some are cancerous or are suspicious for cancer and are commonly removed in a surgical procedure called nephrectomy.

  3. Renal ultrasonography - Wikipedia

    en.wikipedia.org/wiki/Renal_ultrasonography

    Cysts cause posterior enhancement as a consequence of reduced attenuation of the ultrasound within the cyst fluid (Figure 5). The simple cyst is a benign lesion, which does not require further evaluation. [1] Complex cysts can have membranes dividing the fluid-filled center with internal echoes, calcifications or irregular thickened walls.

  4. Urinary tract ultrasound - Wikipedia

    en.wikipedia.org/wiki/Urinary_tract_ultrasound

    Ultrasound involves a probe that is placed near a structure and uses the transmission of ultrasound waves through a structure to produce images, after computer processing. [1] Ultrasound of the urinary tract is performed by a probe placed on the abdominal wall, called a transducer. [1] This occurs while a person is lying down. [1]

  5. Hydronephrosis - Wikipedia

    en.wikipedia.org/wiki/Hydronephrosis

    For incidentally detected prenatal hydronephrosis, the first study to obtain is a postnatal renal ultrasound, since as noted, many cases of prenatal hydronephrosis resolve spontaneously. This is generally done within the first few days after birth, although there is some risk that obtaining an imaging study this early may miss some cases of ...

  6. Renal cell carcinoma - Wikipedia

    en.wikipedia.org/wiki/Renal_cell_carcinoma

    Ultrasonographic examination can be useful in evaluating questionable asymptomatic kidney tumours and cystic renal lesions if computed tomography imaging is inconclusive. This safe and non-invasive radiologic procedure uses high frequency sound waves to generate an interior image of the body on a computer monitor.

  7. Multicystic dysplastic kidney - Wikipedia

    en.wikipedia.org/wiki/Multicystic_dysplastic_kidney

    Multicystic dysplastic kidney (MCDK) is a condition that results from the malformation of the kidney during fetal development. The kidney consists of irregular cysts of varying sizes. Multicystic dysplastic kidney is a common type of renal cystic disease, and it is a cause of an abdominal mass in infants. [5]

  8. Renal pelvis - Wikipedia

    en.wikipedia.org/wiki/Renal_pelvis

    The renal pelvis is the location of several kinds of kidney cancer and is affected by infection in pyelonephritis. [citation needed] A large "staghorn" kidney stone may block all or part of the renal pelvis. The size of the renal pelvis plays a major role in the grading of hydronephrosis.

  9. Kidney tumour - Wikipedia

    en.wikipedia.org/wiki/Kidney_tumour

    The RENAL Nephrometry Scoring System is used to measure the complexity of kidney tumors for determining whether a renal mass is appropriate for partial or radical nephrectomy, and is estimated by CT scan as follows: [7] The nephrometery score takes into account the size of the tumor (Radius), how much of the tumor is inside or outside of the ...
