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]
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 ...
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 ...
Nephrolithiasis (kidney stones) Can cause hydronephrosis (swollen kidneys) and kidney failure; Can predispose to pyelonephritis (kidney infections) Can progress to urolithiasis; Urolithiasis (urinary bladder stones) Can progress to bladder outlet obstruction; Cholelithiasis (gallstones)
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 ]
Dent's disease (or Dent disease) is a rare X-linked recessive inherited condition that affects the proximal renal tubules [1] of the kidney.It is one cause of Fanconi syndrome, and is characterized by tubular proteinuria, excess calcium in the urine, formation of calcium kidney stones, nephrocalcinosis, and chronic kidney failure.
Non-contrast CT (at left) showing peripelvic fluid accumulations, which may be hydronephrosis. CT urography (at right) reveals non-dilated calyces and pelvises. The fluid accumulations are thus peripelvic cysts. Parapelvic cysts originate from around the kidney at the adjacent renal parenchyma, and plunge into the renal sinus. Peripelvic cysts ...
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).
