Ultrasound of the urinary tract involves the use of an ultrasound probe to image parts of the urinary tract. The urinary tract is the path that urine follows after it is formed within the kidneys , and involves a left and right ureter , the bladder , and the urethra .
Urinary bladder disease includes urinary bladder inflammation such as cystitis, bladder rupture and bladder obstruction (tamponade).Cystitis is common, sometimes referred to as urinary tract infection (UTI) caused by bacteria, bladder rupture occurs when the bladder is overfilled and not emptied while bladder tamponade is a result of blood clot formation near the bladder outlet.
A bladder ultrasound may be conducted to view how much urine is within the bladder, indicating urinary retention. A urinary tract ultrasound , conducted by a more trained operator, may be conducted to view whether there are stones, tumours or sites of obstruction within the bladder and urinary tract.
Common findings, determined by ultrasound of the bladder, include a slow rate of flow, intermittent flow, and a large amount of urine retained in the bladder after urination. A normal test result should be 20–25 ml/s peak flow rate. A post-void residual urine greater than 50 ml is a significant amount of urine and increases the potential for ...
Neurogenic bladder dysfunction, often called by the shortened term neurogenic bladder, refers to urinary bladder problems due to disease or injury of the central nervous system or peripheral nerves involved in the control of urination. [1] [2] There are multiple types of neurogenic bladder depending on the underlying cause and the symptoms.
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.
Ultrasound scan of a fetus with megacystis. Fetal megacystis is diagnosed during pregnancy by ultrasound imaging procedures. Since it can be associated with genetic abnormalities, further ultrasounds and tests may be administered during pregnancy.
[1] [2] Urine normally travels in one direction (forward, or anterograde) from the kidneys to the bladder via the ureters, with a one-way valve at the vesicoureteral (ureteral-bladder) junction preventing backflow. The valve is formed by oblique tunneling of the distal ureter through the wall of the bladder, creating a short length of ureter (1 ...
