May rarely present with features of acute kidney injury or chronic kidney disease. [patient.info]
IH patients present frequently with gross or microscopic hematuria, abdominal pain and a variety of urinary tract complaints (frequency-dysuria syndrome, enuresis, recurrent tract infection), with-noncalculus manifestation more prevalent than stone disease [eurekaselect.com]
Arguments are presented for the concept that the primary abnormality in idiopathic hypercalciuria is neither renal calcium hyperexcretion nor intestinal calcium hyperreabsorption, but a more fundamental disturbance in calcium metabolism of as yet unknown [jci.org]

- Weakness
FHHNC patients.Some authors reported elevated PTH early in the courseof the disease independent of GFR.2 The usual presenting features of this syndrome arepolyuria, increased frequency and excessive thirst.Tetanic convulsions, muscle cramps and muscle weakness [japi.org]
A weak negative correlation between renal Sr 2+ clearance (CR E ) and plasma concentrations of PTH was observed in normocalciuric patients, indicating the control that PTH exerts similar on tubular Sr 2+ reabsorption as on tubular Ca 2+ transport ( 15 [clinchem.aaccjnls.org]
- Fatigue

Gastrointestinal
- Diarrhea
Pregnant women, patients with intestinal pathologies, chronic diarrhea or using corticoids were excluded. [nutritionj.biomedcentral.com]
Musculoskeletal
- Osteopenia
Recently, osteopenia has been found in a high percentage of IH children even at the time of diagnosis. [eurekaselect.com]
Morbidity associated with idiopathic hypercalciuria is chiefly related to kidney stone disease and bone demineralisation leading to osteopenia and osteoporosis. [cochrane.org]

Urogenital
- Polyuria
These children were checked for polyuria, concentrating defects, and their fluid intake. The renal functions in all patients were checked and if there was any decrease in renal function, they were excluded from the study. [sjkdt.org]
Hypercalcaemia: polyuria and polydipsia, nausea and vomiting. May cause hypertension. [patient.info]
The transplant outcome and acute rejectionrates were similar to control subjects.4 To our knowledgethere is only one previous case report from India byRakesh Lodha et al,6 a fourteen year old girl with failureto thrive, polyuria and polydypsia. [japi.org]
The young man had polyuria and radiological nephrocalcinosis demonstrated by a concentration defect resistant to pitressin (260 mOsm/l), which seemed to contribute to the existing hypokalaemia (2.5-3.2mEq/l), given the secondary hyperaldosteronism. [revistanefrologia.com]
- Kidney Failure
Although kidney stones are not a significant cause of kidney failure, epidemiological data suggest that most people who develop kidney stones have mildly compromised kidney function (Gillen 2005). [cochranelibrary.com]
- Renal Insufficiency
Chronic hypercalcinuria may lead to impairment of renal function, nephrocalcinosis, and renal insufficiency. Patients with hypercalciuria have kidneys that put out higher levels of calcium than normal. [en.wikipedia.org]

Treatment
If diagnosed promptly and appropriate treatment is provided, then the outlook is good If the individual responds to various treatment measures, the prognosis is generally better, compared to those who do not respond favorably to treatment Additional and [dovemed.com]
Several pharmacological treatments have been described that can decrease the levels of urinary calcium or its index of urinary crystallization. [cochrane.org]
They were randomly allocated to treatment group or control group. The mean age of the patients in the treatment group was 8.02 ± 1.67 years, and in control group was 8.47 ± 1.64 years ( P = 0.20). [sjkdt.org]
A variety of genes participating in the mechanisms of Ca homeostasis, have attracted the interest of researchers in order to elucidate the pathogenetic mechanism of the disease and thus determining the appropriate treatment for any distinct patient. [eurekaselect.com]

Prognosis
What is the Prognosis of Idiopathic Hypercalciuria? (Outcomes/Resolutions) The prognosis of Idiopathic Hypercalciuria depends on the severity of the condition. [dovemed.com]
Prognosis The prognosis depends mainly on the aetiology of the nephrocalcinosis. [patient.info]
