A case of unilateral nephrocalcinosis was presented in a 14-year-old Korean adolescent, with chief complaints of vague or dull pain of the left flank region for about 2 months duration, especially during exertion. Clinical and radiological study confirmed that the left kidney showed total and diffuse calcification and Accordingly stony consistency proved. Postoperatively. Surgical removal of the kidney was successful and uneventful with complete disappearancesof the complaints Brief review of literature was also made.

Acute phosphate nephropathy (APhN) following oral sodium phosphate solution (OSP) ingestion as a bowel purgative has been frequently reported. It was recently suggested that APhN could progress to chronic kidney disease (CKD) and a history of APhN might be considered as one of the causes of CKD. However, there are few reports proving APhN as a cause of CKD. Here, we report a case of APhN that progressed to CKD, as proven by renal biopsy.

Renal involvement is not uncommon in primary Sjogren's syndrome; however, it is clinically insignificant in most cases. Distal renal tubular acidosis accounts particularly for the majority. While the underlying distal renal tubular acidosis is an important cause of nephrocalcinosis and urolithiasis, nephrocalcinosis is rarely a presenting feature of primary Sjogren's syndrome. We report a 65-year-old woman who was diagnosed with distal renal tubular acidosis accompanied by primary Sjogren's syndrome, according to nephrocalcinosis, which was incidentally identified by an abdominal ultrasonography during a medical examination.

There are several diseases characterized by neurologic abnormalities and renal disease. Joubert syndrome is one of them. Joubert syndrome is a relatively rare autosomal recessive syndrome. The most significant and constant neurologic finding is hypoplasia of the cerebellar vermis. Joubert syndrome is associated with hypotonia, retinal dystrophy, abnormal eye movement, delayed development, abnormal respiratory pattern (neonatal episodic tachypnea or apnea) and nephronophthisis. We report a boy with Joubert syndrome associated with nephrocalcinosis and agenesis of the cerebellar vermis. This patient had also abnormal eye movement, hypotonia, abnormal respiratory pattern, delayed development and chronic renal failure.

Renal stone and nephrocalcinosis are common clinical manifestations of type 1 renal tubular acidosis. In normal state, citrate plays the most critical role in suppressing stone formation as it combines with calcium. In type 1 RTA, increased reabsorption of citrate in proximal tubule results in low citrate excretion, which precipitates renal stone formation. We report a case of type 1 RTA accompanying renal stone and nephrocalcinosis caused by hypocitraturia. A 16-year-old male patient who had renal stone and nephrocalcinosis showed hypocitraturia. Incomplete type 1 RTA was proved as the cause of hypocitraturia by bicarbonate and ammonium loading test in the patient.

Bartter syndrome is characterized by markedly reduced or absent salt transport by the thick ascending limb of Henle. The phenotype of Bartter syndrome is renal salt wasting, hypokalemic metabolic alkalosis, increased renin-angiotensin-aldosterone system, with normal or low blood pressure. Most of the cases have been noted in the pediatric age group and adult-onset cases are rare. Nephrocalcinosis is common in antenatal Bartter syndrome. We report a case of adult-onset Bartter syndrome associated with nephrocalcinosis.

Distal renal tubular acidosis (RTA) is characterized by a decreased net H+ secretion in the collecting tubules, which results in a failure of urine acidification and results in metabolic acidosis, hypokalemia, and nephrocalcinosis. The acquired form of distal RTA is associated with tubulointerstitial involvement of immune-mediated disorders such as Sjogren's syndrome and systemic lupus erythematosus (SLE). Only a few case reports have indicated that distal RTA precedes SLE by months to years. We present a 39-year-old woman who had manifestations of distal RTA for 21 years before the development of overt symptoms of SLE.
