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]
Pelvic abscess is a collection of pus in the pelvis, typically occurring following lower abdominal surgical procedures, or as a complication of pelvic inflammatory disease (PID), appendicitis, or lower genital tract infections. [1] Signs and symptoms include a high fever, pelvic mass, vaginal bleeding or discharge, and lower abdominal pain. [1]
Bladder outlet obstruction is included in the spectrum of congenital anomalies of the kidney and urinary tract (CAKUT). CAKUT is the most common cause of birth defects, occurring in 1 out of 1000 live births, and accounts for approximately half of all cases of chronic kidney disease and end-stage renal disease in children.
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;
The exam ends when the person voids while the radiologist is watching under fluoroscopy. Consumption of fluid promotes excretion of contrast media after the procedure. It is important to watch the contrast during voiding, because this is when the bladder has the most pressure, and it is most likely this is when reflux will occur.
Initially, a thin tube is placed through the skin just above the pubic bone into the bladder, often with the assistance of ultrasound imaging. [2] This catheter initially remains in place for up to a month while the tissue around it scars and forms a tract ( sinus ) between the bladder and the body exterior.
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 this case, the procedure may require more extensive preparation and take more time to perform. Also, fine-needle aspiration is the main method used for chorionic villus sampling, [3] as well as for many types of body fluid sampling. It is also used for ultrasound-guided aspiration of breast abscess, [4] of breast cysts, and of seromas. [5]
