At the time of admission, hypercalciuria and nephrocalcinosis
and/or nephrolithiasis were found in 46/57 (81%) of cases with available data and 33/68 patients (48.5%) of cases with available data, respectively.
The median age at diagnosis of PH1 is between 4.2 and 11.5 years, depending on whether nephrocalcinosis
(calcification in the renal parenchyma, the functional part of the kidney) is present.5 Fifty percent of patients with PH1 reach end-stage renal disease by their mid-30s.
Presence of nephrolithiasis or nephrocalcinosis
by x-ray, ultrasound, or CT Age, years <50 BMD, bone mineral density; DEXA, dual-energy x-ray absorptiometry; CT, computed tomography; MRI, magnetic resonance imaging; VFA, vertebral fracture assessment.
is the precipitation of calcium phosphate crystals in the renal tubules that can result in nephrolithiasis and cause or further provoke an obstructive uropathy.
Kidney ultrasonography showed cortical nephrocalcinosis
. We observed shortening of the third metacarpal of the left hand during physical examination and radiography (Figure 2a, b).
5: Common fish diseases observed at participating laboratories Disease name Causative organism(s) or conditions Noninfectious High C[O.sub.2] (e.g., > 12 mg/l) in nephrocalcinosis

Starvation, gout, renal disease, nephrocalcinosis
(vitamin D excess), dehydration, and chronic hypovitaminosis A may cause changes in the uric acid concentration.
A total of 12 infants were excluded from the study because of abnormalities incidentally detected by sonographic evaluation (7 hydronephrosis, 1 nephrocalcinosis
and 4 surrenal haematoma).

Maintaining serum calcium in the low-normal range 8.0 mg/ dL (2.00-2.12 mmol/L), maintaining serum phosphorus within a normal range, and maintaining a calcium-phosphate product below 4.4 [mmol.sup.2]/[L.sup.2] (55 [mg.sup.2]/d[L.sup.2]) without developing hypercalciuria, which leads to nephrocalcinosis
or nephrolithiasis, and renal impairment.
