Ultrasonography of the kidneys (renal ultrasound) is part of a complete examination of the abdomen. Ultrasound is used to determine the size, shape, and exact position of the kidneys. Renal ultrasound provides important information regarding kidney function, related blood vessels, kidney stones, renal cysts, tumors, or hydronephrosis (suggestive of obstruction or blockage of the kidney).
The kidneys are scanned on longitudinal and transverse planes. Patients should avoid carbonated drinks such as soda or seltzer the day before, and have a full bladder for the test.
Lithotripsy is a therapeutic ultrasound procedure used to shatter simple stones in the kidney or upper urinary tract.

LithotripsyMRI Resource Directory:<br> - Ultrasound Therapy -
 
(ESWL) Extracorporeal shock wave lithotripsy is a special use of kidney ultrasound, where high intensity focused ultrasound pulses are used to break up calcified stones in the kidney, bladder, or urethra. Pulses of sonic waves pulverize dense renal stones, which are then more easily passed through the ureter and out of the body in the urine. The ultrasound energy at high acoustic power levels is focused to a point exactly on the stone requiring an ultrasound scanning gel for maximum acoustic transmission.
Air bubbles in the ultrasound couplant, regardless of their size, degrade the performance of Lithotripsy and have the following effect:
Air bubbles smaller that 1/4 wavelength cause scattering of the sound waves as omni directional scatterers and less acoustic energy reaches the focal point. The result is less acoustic power at the focal point to disintegrate the kidney stone.
Air bubbles larger than 1/4 wavelength act as reflectors and deflects the acoustic energy off in a different direction. These results in less acoustic energy at the focal point.
Microbubbles dispersed throughout the ultrasound couplant layer change the average acoustic impedance of the gel layer (which reduces the total transmitted energy) and, due to refraction, change the focal point.

Reflux SonographyMRI Resource Directory:<br> - Renal -
 
Reflux sonography, as an alternative to micturating cystography (MCU), evaluates vesico-ureteral reflux (VUR), a common problem in children. Contrast enhanced pulse-inversion imaging shows best results. During the instillation of an ultrasound contrast agent into the bladder, (as for a conventional MCU) the lower ureters and renal pelves are scanned transabdominally as the bladder is filled to stimulate micturition.
Advantages for reflux sonography are a high sensitivity and the avoidance of X-rays. A disadvantage is the poorer depiction of the posterior urethra. However, for girls and for all follow-up studies, the ultrasound MCU has become standard in many pediatric ultrasound departments.

Urologic UltrasoundMRI Resource Directory:<br> - Kidney -
 
Urologic ultrasound includes the examination of the kidneys, renal vessels, urinary tract, bladder, prostate, and scrotum.
Usual gray scale ultrasound equipment and standard probes are sufficient to examine the kidney parenchyma and renal pelvis, the urinary tract and bladder. Doppler ultrasound is a useful adjunct to kidney ultrasound. High ultrasound system performance is desirable to show the arterial system, because advanced power Doppler is significantly more sensitive to blood flow than standard color Doppler.
Transurethral sonography may be used to examine the bladder and urethra. Transrectal sonography is used to scan and treat the prostate e.g., with brachytherapy or high intensity focused ultrasound. Very small probes are used for these applications. Reflux sonography is especially used in pediatric ultrasound.

(AUS) Abdominal ultrasound, (TAE) transabdominal echography, abdomen sonography, sonogram, (FAST) focused assessment
Ultrasonography is an ideal clinical tool for determining the source of abdominal pain. An abdominal ultrasound includes the liver, gallbladder, biliary tree, pancreas, spleen, kidneys and blood vessels of the abdomen. Conventional ultrasound is cheap, safe, non-invasive and is a practical first line investigation. High resolution ultrasound, endoscopic ultrasound and contrast enhanced Doppler techniques assist in detecting small lesions. The best preparation is nothing to eat or drink from midnight the night before the exam (minimum 8 hours).

Indications:
point abdominal pain;
point stones in the gallbladder or kidneys;
point inflammation;
point cancer, metastasis.

FAST is a rapid diagnostic test of the trauma patient that sequentially detects the presence of free fluid in pericardium (hemopericardium) and in 4 views of the abdomen. These views, the right upper quadrant (RUQ), left upper quadrant (LUQ), the subcostal, and suprapubic views detect a hemoperitoneum in patients with potential truncal injuries. The Morison pouch between the liver and right kidney (RUQ) is a space in which intraperitoneal fluid can accumulate. Emergency abdominal ultrasonography is indicated for the evaluation of aortic aneurysm, appendicitis, and biliary and renal colic, as well as blunt or penetrating abdominal trauma.
