Vanishing hypercalciuric kidney stones after treating underlying acromegaly
UNLABELLED A 53-year-old male presented with recurrent calcium oxalate kidney stones as a first sign of underlying acromegaly, which vanished when his acromegaly was controlled. The exact mechanism behind hypercalciuria and urolithiasis in acromegaly is not yet clear. By discussing this case, a short overview of the pathophysiology of hypercalciuria in acromegaly and practical insights are give...
متن کاملSignificance of the calcium to creatinine concentration ratio of a single-voided urine specimen in patients with hypercalciuric urolithiasis.
Thirty-six patients with recurrent calcium oxalate nephrolithiasis were selected from the stone clinic. Fourteen were normocalcemic and had normal daily urinary calcium excretion. Among 22 patients with idiopathic hypercalciuria, 10 received thiazide diuretics for the prevention of new stone formation. Single-voided urine samples were collected at the outpatient clinic and 24-hour urine at the ...
متن کاملUrine with stones: nephrocalcinosis and vitamin D
Background Nephrocalcinosis (NC) refers to diffuse, fine, renal parenchymal calcification, as assessed by radiology or ultrasonography. In medullary NC, the calcification tends to occur in the area of the renal pyramids. It is typically associated with elevated urinary calcium, phosphate, and oxalate, or it can occur with alkaline urine. Any disorder that can lead to hypercalcemia or hypercalci...
متن کاملIntestinal Calcium Absorption among Hypercalciuric Patients with or without Calcium Kidney Stones.
BACKGROUND AND OBJECTIVES Idiopathic hypercalciuria is a frequent defect in calcium kidney stone formers that is associated with high intestinal calcium absorption and osteopenia. Characteristics distinguishing hypercalciuric stone formers from hypercalciuric patients without kidney stone history (HNSFs) are unknown and were explored in our study. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS...
متن کاملUrine risk factors in children with calcium kidney stones and their siblings
Calcium nephrolithiasis in children is increasing in prevalence and tends to be recurrent. Although children have a lower incidence of nephrolithiasis than adults, its etiology in children is less well understood; hence, treatments targeted for adults may not be optimal in children. To better understand metabolic abnormalities in stone-forming children, we compared chemical measurements and the...
