medullary sponge kidney/potassium

Renal tubular function, with special emphasis on potassium excretion, was studied in three patients with medullary sponge kidney (MSK). Urinary acidification and concentration abilities were impaired, while glomerular filtration rates remained normal. After short-term intravenous (IV) potassium

OBJECTIVE Medullary sponge kidney (MSK) is a renal malformation typically associated with nephrocalcinosis and recurrent calcium stones. Incomplete distal renal tubular acidosis, hypocitraturia, and hypercalciuria are common. For stone prevention, patients with MSK generally receive the standard

OBJECTIVE In medullary sponge kidney (MSK)-a common malformative renal condition in patients with calcium nephrolithiasis-hypercalciuria, incomplete distal renal tubular acidosis, and hypocitraturia are common. Clinical conditions with concomitant hypercalciuria and/or incomplete distal renal

A case of successful renal calculus dissolution by the combined treatment which consists of irrigation with ethylenediaminetetraacetic acid (EDTA), potassium citrate, and extracorporeal shock-wave lithotripsy (ESWL) is described here. Renal irrigation via nephrostomy, which was the main treatment,

A 55-year-old man with normotensive primary aldosteronism, hypopituitarism, epilepsy, and medullary sponge kidney is reported. Seventeen years before admission, he had been noted to have hypokalemia associated with high potassium clearance, suppressed plasma renin activity, metabolic alkalosis, and

Medullary Sponge Kidney (MSK) disease is a rare congenital malformation of the distal nephron where cystic dilatation is appreciable in the collecting ducts and renal papillae. Most cases of the malformation are thought to arise from a malfunction within neurotrophic factor and tyrosine kinase

Medullary sponge kidney (MSK) is a renal malformation typically associated with nephrocalcinosis and recurrent calcium nephrolithiasis. Approximately 12% of recurrent stone formers have MSK, which is generally considered a sporadic disorder. Since its discovery, three pedigrees have been described

Eight patients (6 women and 2 men) with osteoporosis caused or aggravated by renal acidification defects are presented. Three of the female patients were premenopausal; the others were 9, 20 and 22 years postmenopausal, and two of them were on hormonal replacement therapy. Two patients had

The functions of a kidney, whether normal or cystic, can be conceptualized in terms of anatomy (glomerulus, proximal tubule, loop of Henle, distal convolution, and collecting duct), activity (volume regulation, dilution and concentration, acid-base regulation, potassium excretion, transport of

Very few patients with familial hypomagnesemia, hypercalciuria and nephrocalcinosis have been described. Information about clinical course, familial studies or evolution after renal transplantation is very scant. We have studied eight patients with this syndrome who belong to five different
