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]
15 minute X-ray of just the renal area. At this point, compression may or may not be applied (this is contraindicated in cases of obstruction). In pyelography, compression involves pressing on the lower abdominal area, which results in distension of the upper urinary tract. [8] If compression is applied: a 10 minutes post-injection X-ray of the ...
Under normal conditions, the ureter is not seen with US. However, in, e.g., urinary obstruction and vesicoureteric reflux with dilation of the ureter, the proximal part in continuation with the renal pelvis, as well as the distal part near the ostium can be evaluated (Figure 14). [1]
In children, abdominal x-ray is indicated in the acute setting: Suspected bowel obstruction or gastrointestinal perforation; Abdominal x-ray will demonstrate most cases of bowel obstruction, by showing dilated bowel loops. [1] Foreign body in the alimentary tract; can be identified if it is radiodense. [1] Suspected abdominal mass [1]
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. It requires less radiation than pelvic CT, although it is less sensitive and specific than MRI or CT.
It is, however, only since the 1500s that the term "ureter" has been consistently used to refer to the modern structure, and only since the development of medical imaging in the 1900s that techniques such as X-ray, CT, and ultrasound have been able to view the ureters.
An open cystolithotomy is performed under general anesthesia as an inpatient procedure. The first step is a cystoscopy to examine the bladder, then an incision is made in the lower abdomen. Once the stone is removed, the bladder is repaired with an absorbable stitch, and a catheter is inserted into the bladder via the urethra .
Retrograde pyelogram (RPG): X-ray study of the kidney, focusing on the urine-collecting region of the kidney and ureters. Antegrade nephrostogram. CT scan: An imaging technique that uses a computer to collect multiple X-ray images into a two-dimensional cross-sectional image. MRI with intravenous gadolinium. A special technique used to image ...
