Urinary infection in renal stone patients.

Urinary infection is found in less than 10% of renal stone formers. It is three times more common in women than in men. Urea-splitting bacteria (Proteus, Klebsiella, pyocyaneus, staphylococcus) leading to stone formation are identified in two thirds of the cases. The percentage of the different bacteria varies depending upon the sex and degree of resistance to therapy. The sensitivity of bacteria to eight commonly used drugs was investigated.

High fluid-low calcium intake: not all renal stone formers adhere to this simple treatment.

FActors predisposing to renal stone formation have been studied in 309 patients. Dehydration before diagnosis of urolithiasis was due in 12% of the cases to frequent diarrhea and in 36% to bad working conditions. Daily fluid intake was less than 1 liter in 25% of the patients before stone formation and was persistently low in 11% after stone discovery. 41% of the patients drank irregularly over the day, before stone formation, and 11% continued to do so after its detection. Immobilization was present in the patient's history in over 20% of the cases. Normocalcemic hypercalciuria was found in 26% of the patients. 24% of the patients drank water with a calcium concentration of 100--500 mg/l before the lithiasis was diagnosed; 21% continued to do so after stone discovery or paradoxically even drank harder water than before stone detection.

Effect of rapid variation of renal function on plasma calcitonin and parathyroid hormone in man.

Plasma levels of immunoreactive calcitonin (iCT) and parathyroid hormone (iPTH) have been measured sequentially in 6 patients following successful renal transplantation (RT) and in 3 patients during the recovery phase of acute renal failure (ARF). iCT and iPTH returned to normal values within a few days when glomerular filtration improved; both hormones rose in cases of acute graft rejection. Unlike iPTH iCT did not follow closely the variations of creatinine, iCT even rising before creatinine in one graft rejection. These observations could possibly be explained by a dissociation between the renal metabolism of iCT and the glomerular filtration.

Parathyroid hormone and calcium blood levels in acute renal failure. With special reference to one patient developing transient hypercalcemia.

Parathyroid hormone (PTH), creatinine, calcium and phosphate blood levels were repeatedly measured in 5 patients with acute renal failure. 1 patient developed hypercalcemia during the recovery phase of the illness. PTH was elevated in all cases before starting hemodialysis treatment and returned to normal when renal function recovered. Calcium and PTH were inversely correlated in 3 patients including the patient with transient hypercalcemia. These data show that parathyroid function in acute renal failure is closely related to changes in renal function and the hypercalcemia, when occurring, is not necessarily due to parathyroid hyperactivity.

Chemical analysis of renal stones from 377 Belgian patients by using qualitative or quantitative methods.

The renal stones of 377 patients from the Brussels' area have been studied by chemical methods; 239 stones were submitted to qualitative analysis and the other 138 to a quantitative analysis. The results of the study demonstrate that, in Belgium as well as in other Western countries like the USA and Great Britain, calcium oxalate, calcium phosphate and magnesium ammonium phosphate are, in decreasing order of frequency, the major constitutents of renal calculi. The fact that calcium oxalate-containing stones are mainly found in men associated with sterile urine, and magnesium ammonium phosphate stones in women associated with urinary infection, is confirmed in the present series. The percentage of uric acid-containing stones is similar to that in the USA and Great Britain, but lower than that observed in several European countries including France, Spain, Germany, Czechoslovakia and Sweden. A small group of Mediterranean patients living in Belgium show no specific pattern, suggesting that the formation of calculi could be more dependent upon environmental than upon ethnic factors.

The use of a test for the differential diagnosis of hypercalciuria.

28 renal stone formers (18 men and 10 women) with idiopathic hypercalciuria (IH) and 27 controls have been subjected to a test proposed for the diagnosis of absorptive, resorptive and renal hypercalciurias. Fasting serum calcium concentration, urinary calcium and cyclic AMP excretion were measured after overnight fasting and an oral load of calcium. Absorptive hypercalciuria was demonstrated in 14 patients. High fasting urinary calcium first suggested resorptive or renal hypercalciurias in 5 other patients, but since fasting urinary calcium was normalized following cellulose phosphate therapy, absorptive hypercalciuria was more likely. Renal hypercalciuria was a possibility in 1 single case. Both fasting and post-load urinary calcium were normal in 7 men and 1 woman. The test did not appear as useful as expected since it was of no diagnostic value in about 30% of the cases and erroneously suggested resorptive or renal hypercalciuria in about 15% of the cases. On the other hand it indicated that absorptive IH is common and renal IH exceptional.

Metabolism of human PTH by the kidney and the liver.

Immunoreactive PTH was measured by amino terminal and carboxyl terminal specific assays in the femoral artery, the right renal vein and the suprahepatic vein of ten hyperparathyroid patients. A marked arterio venous difference for amino terminal immunoreactivity was observed in the kidney and the liver. In contrast, the arterio venous difference for carboxyl terminal immunoreactivity was small in the kidney and not significantly in the liver. It is concluded that intact PTH and possibly amino terminal fragments of the hormone are metabolized by the kidney and the liver. Considering the fact that a carboxyl terminal specific antiserum is also capable of recognizing intact hormone, the finding of a small positive arterio venous difference for carboxyl terminal immunoreactivity does not permit us to exclude the possibility that the kidney and/or the liver are capable of generating carboxyl terminal fragments.
