Kidney stone disease, also known as renal calculus disease, nephrolithiasis or urolithiasis, is a crystallopathy where a solid piece of material (renal calculus) develops in the urinary tract. [2] Renal calculi typically form in the kidney and leave the body in the urine stream. [2] A small calculus may pass without causing symptoms. [2]
Nephrocalcinosis is closely associated with nephrolithiasis, and patients frequently present with both conditions, however there have been cases where one occurs without the other. [1] Calcium oxalate and calcium phosphate crystals form when the concentration of the reactants exceeds the limit of solubility of these compounds under the ...
Human gallstones, all removed from one patient. Grid scale 1 mm. Calculi in the inner ear are called otoliths; Calculi in the urinary system are called urinary calculi and include kidney stones (also called renal calculi or nephroliths) and bladder stones (also called vesical calculi or cystoliths).
Where available, a noncontrast helical CT scan with 5 millimeter sections is the diagnostic modality of choice in the radiographic evaluation of suspected nephrolithiasis. [ 16 ] [ 17 ] [ 18 ] All stones are detectable on CT scans except very rare stones composed of certain drug residues in the urine. [ 19 ]
Medullary sponge kidney is a congenital disorder of the kidneys characterized by cystic dilatation of the collecting tubules in one or both kidneys.Individuals with medullary sponge kidney are at increased risk for kidney stones and urinary tract infection (UTI).
The signs and symptoms of hydronephrosis depend upon whether the obstruction is acute or chronic, partial or complete, unilateral or bilateral. Hydronephrosis that occurs acutely with sudden onset (as caused by a kidney stone) can cause intense pain in the flank area (between the hips and ribs) known as a renal colic. Historically, this type of ...
Hydronephrosis is the enlargement of one or both of the kidneys caused by obstruction of the flow of urine. Interstitial nephritis is inflammation of the area of the kidney known as the renal interstitium. Kidney stones (nephrolithiasis) are a relatively common and particularly painful disorder. A chronic condition can result in scars to the ...
Most patients present with both manifestations, but some present with loin pain or hematuria alone. Pain episodes are rarely associated with low-grade fever and dysuria, but urinary tract infection is not present. The major causes of flank pain and hematuria, such as nephrolithiasis and blood clot, are typically not present. Renal arteriography ...
