Ultrasound imaging is useful for detecting stones in situations where X-rays or CT scans are discouraged, such as in children or pregnant women. [67] Despite these advantages, renal ultrasonography in 2009 was not considered a substitute for noncontrast helical CT scan in the initial diagnostic evaluation of urolithiasis. [66]
Figure 18. Renal stone located at the pyeloureteric junction with accompanying hydronephrosis. [1] With US, larger stones (>5–7 mm) within the kidney, i.e., in the calyces, the pelvis and the pyeloureteric junction, can be differentiated, especially in the cases with accompanying hydronephrosis (Figure 18 and Figure 19).
Some stone types (mainly those with substantial calcium content) can be detected on X-ray and CT scan; Many stone types can be detected by ultrasound; Factors contributing to stone formation (as in #Etiology) are often tested: Laboratory testing can give levels of relevant substances in blood or urine
A kidney stone is a hard object, which can be as small as a grain of salt or as big as a golf ball, made from chemicals—calcium oxalate, uric acid, struvite, and cystine—found in our urine ...
This has the advantage of showing whether there is any obstruction of flow of urine causing hydronephrosis as well as demonstrating the function of the other kidney. Many stones are not visible on plain X-ray or IVU but 99% of stones are visible on CT and therefore CT is becoming a common choice of initial investigation. CT is not used, however ...
Patients with a kidney stone and obstruction are usually required to stay in hospital for monitoring or further treatment. An Emergency IVP is carried out roughly as follows: plain KUB or abdominal X-ray; an injection of contrast media, typically 50 ml; delayed abdominal X-ray, taken at roughly 15 minutes post injection.
