Hyperphosphaturia

Hyperphosphaturia is renal phosphate wastage. It frequently results in hypophosphatemia. Also osteoporosis and nephrocalcinosis can be observed.

Physiology

Phosphat metabolism

Diseases

Dent disease
Hyperphosphaturia is sometimes difficult to measure. However, it is of cardinal importance to the development of nephrocalcinosis and hypophaspatemia related bone disease.
Fanconi renotubular syndrome 2
Renal phosphate wasting is observed along with other symptoms of proximal tubular damage..
Hypophosphatemic rickets with hyperparathyroidism
Hyperphosphaturia is caused by downregulation of phosphate transporters.
Osteoglophonic dysplasia
Hyperphosphaturie is caused by disrupted intracellular signaling in proximal tubulus cells.
