12 adult patients with medullary sponge kidney (MSK), followed up for 1 to 14 years (mean 7 years) are presented. MSK was initially diagnosed in 4 cases. In 8 cases the initial diagnosis included pyelonephritis, nephrocalcinosis, and nephrolithiasis. Renal calculi (4 patients), urinary tract infection (8) and hematuria (5) were the most frequent symptoms. Renal tubular acidosis was documented in 2 patients and hypercalciuria without hyperparathyroidism in 2. Over the years renal calculi increased in size in 4 patients. Renal function was stable in 11. In one patient with associated, well controlled hypertension, serum creatinin rose from 141 to 298 mumol/l over 14 years.

The authors report 17 personal cases of lithiasis of the upper urinary tract discovered in the course of pregnancy. They discuss the diagnostic and therapeutic problems, taking into account the double risk of mother and foetus. The essential diagnostic sign is renal colic, with or without fever. Spontaneous excretion of these calculi is possible, but in 8 of the 17 cases, a ureteric catheter had to be passed or an operation was required. Neither the delivery nor the health of the infants delivered seemed to be harmed by this renal calculi disease. The authors recall that the most common cause of non-obstetrical abdominal pain in the course of pregnancy is in fact urinary calculi. The incidence is about 1 cases of lithiasis per 1,000 pregnancies. It appear that a physiological hyperparathyroidism of pregnancy is responsible for a hypercalciuria which could be a factor favouring the development of lithiasis during pregnancy. The important point is to know how to distinguish those forms of pyelonephritis of pregnancy which are due to a stone obstructing the upper urinary tract, as any purulent retention in the upper tract can lead to a pyonephrosis, a bacteraemia or even a septicaemia. The presence of the foetus makes interpretation of a plain abdominal film difficult. In any case, its indication is questionable, whenever the urine is septic, particularly with Proteus.(ABSTRACT TRUNCATED AT 250 WORDS)

The patient, a 30-year-old woman, was admitted to Itoh Hospital in February, 1979 for hyperthyroidism. She had a history of pyelonephritis and recurrent urinary tract infection. Laboratory data on admission revealed overt hyperthyroidism (T3: 405 ng/dl, T4: 22.5 micrograms/dl and T3U: 57.--%), severe hypercalcemia of 12.6 mg/dl and hypercalciuria. The PSP excretion and GFR were both decreased. Serum c-PTH was nondetectable. As the thyroid function improved, there was a gradual decrease and later normalization of plasma calcium, phosphate and urinary calcium excretion. When subtotal thyroidectomy was performed on October 19, 1979, hypertrophy of the parathyroid gland was not demonstrated. In comparison with 98 other hyperthyroid patients, the pathogenesis of hypercalcemia was discussed. In conclusion, hypercalcemia in the patient, T. Y., was regarded as a kind of disequilibrium hypercalcemia which resulted from a combination of increased bone turnover and decreased calcium excretion by the kidney.

We reevaluated the medical records of 112 children with urolithiasis. The prevalence of this condition was 1/4.500 children admitted to our hospital. The mean age was 8.2 years and 54.4% of the afflicted patients were males. Fifty percent of the patients studied had a family history of urolithiasis. The two most frequent etiologies were urinary tract infections and metabolic disorders (hypercalciuria states, distal renal tubular acidosis and cystinuria). The etiology of the urolithiasis was unknown in 15% of our patients. The levels of magnesium and citrate, inhibitors of crystallization, were moderately low in some of the cases in which it was determined. Fifty percent of the children with urolithiasis showed urinary or renal complications. The extracorporeal lithotripsy was an effective treatment of urolithiasis in the patients in which it was performed. The recurrence rate was 8%. In one third of the urolithiasis associated with urinary infections and/or urinary tract malformations we found chronic pyelonephritis.

The exposure of the lumbar region to interference currents in combination with radon baths conducted in 37 patients with chronic pyelonephritis inhibited activity of the inflammation, hypercalciuria and hyperoxaluria, improved function of the kidneys. The same clinical effects were achieved in 32 patients who had received interference therapy in combination with intake of radon water.

We identified 40 pediatric patients with urolithiasis. There were 27 boys and 13 girls. Initial symptoms were abdominal pain, with or without microscopic hematuria in 40% of the cases, and urinary tract infection/pyelonephritis in 25% of the cases. Stones were made of struvite (35% of the cases), calcium-phosphate (25%) or calcium-oxalate (20%). The high prevalence of struvite stones reflects the importance of urinary tract infection a major cause of urolithiasis in that specific age group. Hypercalciuria was the most common urinary biochemical abnormality, found in more than 50% of the children. In the absence of a spontaneous passage of the stone, extra-corporeal shock wave lithotripsy represents an excellent therapeutic option. This article emphasizes the importance of stone analysis and extensive biochemical investigations in children with urolithiasis, in order to avoid recurrence and potential progression towards chronic renal failure.

We report the case of a female patient with incomplete distal renal tubular acidosis with nephrocalcinosis. She was admitted to the hospital because of acute pyelonephritis. Imaging studies showed dual medullary nephrocalcinosis. Subsequent evaluations revealed hypokalemia, hypocalcemia, hypercalciuria, and hypocitraturia with normal acid-base status. A modified tubular acidification test with NH4Cl confirmed a defect of urine acidification, which is compatible with incomplete distal tubular acidosis. We treated our patient with potassium citrate, which corrects hypokalemia and prevents further deposition of calcium salts.
