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]
In the top-right image, the cystoscope has been bent within the bladder to look back on itself. The bottom two images show an inflamed urethra. If a patient has a stone lodged higher in the urinary tract, the physician may use a much finer calibre scope called a ureteroscope through the bladder and up into the ureter. (The ureter is the tube ...
Infants and smaller children can lie down on a table and pee onto absorbent pads. For those children or infants with a neuropathic bladder, pressure on the suprabic region can help them to pee. [2] Fluoroscopic spot images and videos are taken during the micturition phase to detect any reflux.
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 ]
Trabeculated bladder on ultrasound indicates high risk of developing urinary tract abnormalities such as hydronephrosis and stones. [10] A voiding cystourethrography study uses contrast dye to obtain images of the bladder both when it is full and after urination which can show changes in bladder shape consistent with neurogenic bladder. [9]
Abdominal ultrasound is of some benefit, but not diagnostic. Features that suggest posterior urethral valves are bilateral hydronephrosis, a thickened bladder wall with thickened smooth muscle trabeculations, and bladder diverticula. [citation needed] Voiding cystourethrogram (VCUG) is more specific for the diagnosis.
Hemorrhagic cystitis or haemorrhagic cystitis is an inflammation of the bladder defined by lower urinary tract symptoms that include dysuria, hematuria, and hemorrhage.The disease can occur as a complication of cyclophosphamide, ifosfamide and radiation therapy.
The part of the urogenital sinus related to the bladder and urethra absorbs the ends of the Wolffian ducts and the associated ends of the renal diverticula. This gives rise to the trigone of the bladder and part of the prostatic urethra. The remainder of this part of the urogenital sinus forms the body of the bladder and part of the prostatic ...
