Determination of how much urine is in the bladder, for example to assess for urinary retention. To look for evidence and the cause of chronic kidney disease, for example shrunken kidneys. [1] To assist with an interventional procedure, such as the taking of a biopsy, or draining of an abscess or cyst. [1] To monitor a kidney transplant. [1]
The kidneys are easily examined, and most pathological changes in the kidneys are distinguishable with ultrasound. US is an accessible, versatile inexpensive and fast aid for decision-making in patients with renal symptoms and for guidance in renal intervention. [1] Renal ultrasound (US) is a common examination, which has been performed for ...
loss of bladder control (incontinence) or overactive bladder; (Although, the American Urogynecologic Society does not recommend that cystoscopy, urodynamics, or diagnostic renal and bladder ultrasound are part of initial diagnosis for uncomplicated overactive bladder.) [2] [3] unusual cells found in urine sample; need for a bladder catheter;
Abdominal ultrasound can be used to diagnose abnormalities in various internal organs, such as the kidneys, [1] liver, gallbladder, pancreas, spleen and abdominal aorta.If Doppler ultrasonography is added, the blood flow inside blood vessels can be evaluated as well (for example, to look for renal artery stenosis).
Abnormal kidney function may cause too much or too little urine to be produced. The ability of the kidneys to filter protein is often measured, as urine albumin or urine protein levels, [2] measured either at a single instance or, because of variation throughout the day, as 24-hour urine tests.

In radiology and urology, a cystography (also known as cystogram) is a procedure used to visualise the urinary bladder. Using a urinary catheter, radiocontrast is instilled in the bladder, and X-ray imaging is performed. Cystography can be used to evaluate bladder cancer, vesicoureteral reflux, bladder polyps, and hydronephrosis.
In urology, voiding cystourethrography (VCUG) is a frequently performed technique for visualizing a person's urethra and urinary bladder while the person urinates (voids). It is used in the diagnosis of vesicoureteral reflux (kidney reflux), among other disorders. [1]
Additionally, urodynamic testing and a kidney bladder ultrasound are typically performed to assess characteristics of the urinary tract prior to surgery. [20] The urodynamics test should be done within 2 years prior to the procedure and the ultrasound within 1 year. [20]
