The authors examined 133 patients with urolithiasis, treated with hydrochlorothiazide and 81 patients treated with allopurinol. In those treated with hydrochlorothiazide the calciuria and Ca/creat. index declined, and uricaemia rose. After treatment uricosuria increased significantly in 41% patients. The detection of diabetes did not exceed the prevalence in the population. In patients treated with allopurinol the uricaemia and uricosuria declined, a hepatic disorder with supraliminal rise of ALT was recorded in 23% of the patients and led to discontinuation of treatment in 15% of the patients.

We have prospectively studied 37 adult patients (15 males, 22 females; age 31 +/- 10.6 years) with previously undiagnosed isolated hematuria in which hypercalciuria or hyperuricosuria was found. Eighteen of them had had episodes of gross hematuria. Isolated hypercalciuria (4.4 to 10.4, X 5.6 +/- 1.9 mg/kg/24 hr) was found in nine patients (Group I), isolated hyperuricosuria (784 to 1500, X 1088 +/- 228 mg/24 hr) in 11 (Group II), and both hypercalciuria (4 to 8, X 4.9 +/- 1 mg/kg/24 hr) and hyperuricosuria (752 to 1476, X 1042 +/- 181 mg/24 hr) in 17 patients (Group III). Thiazide treatment for patients with hypercalciuria and allopurinol for those with hyperuricosuria were administered; calciuria and uricosuria became normal by the first month of therapy in every case. In 22 (59.4%) cases (Responder patients) hematuria resolved completely as soon as calciuria and uricosuria became normal. In the remaining 15 cases (Nonresponder patients) hematuria persisted despite the normal calcium and uric acid excretions. Several disorders that explained hematuria were diagnosed later in most of Nonresponder patients. Responder patients persisted without hematuria on the follow-up; only in three patients a transient relapse of hematuria was seen associated with a sudden increase of calciuria and uricosuria because of treatment withdrawal. There were no differences in age, male/female ratio nor in the basal values of calciuria and uricosuria between Responder and Nonresponder patients. A familial history of urolithiasis was found more frequently in Responder patients (64%) than in Nonresponders (20%) (P less than 0.05). We conclude that hypercalciuria and hyperuricosuria are definable and potentially reversible causes of hematuria in adult patients.

Urolithiasis diagnosis by uroliths presence reflects insufficient knowledge of the disease pathogenesis. 42 patients with oxalocalcium nephrolithiasis and 20 healthy patients were examined for differences in the urine and plasma composition. The authors studied factors involved in regulation of mineral metabolism and urinary elimination of crystal-forming substances. The patients with urinary stones compared to the control are characterized by low total crystal-inhibiting activity, hyperosmia, hypodipsia, decreased surface free energy, high quantities of ionized calcium, low ionized magnesium in the urine, oligo- and uricosuria. Shifts in hormonal regulation in nephrolithiasis result from slight elevation of urinary cyclic adenosine monophosphate, a relative rise in the levels of aldosterone and parathyroid hormone, low blood calcitonin, all the changes being statistically significant.

Hyperuricosuria (HU), defined as a urinary acid excretion higher than 95 percent of normal values, is an important lithogenic factor, accounting for about 5-20% of recurrent hematuria in childhood. We prospectively studied 30 children (15 male, 15 female; aged 3 to 13 years old) with previously undiagnosed isolated hematuria and HU for 6 to 36 months. The family history of nephrolithiasis was positive in 40%. Idiopathic hypercalciuria (IH), UCa > 4 mg/kg/day, was not found initially, but was diagnosed after 6 to 24 months in 20% of the patients. The following treatments were utilized: restricted purine diet (13%), allopurinol (4%) and potassium citrate (1%). No specific treatment was given to 82% of the patients. Therapy normalized uricosuria with resolution of hematuria over 6-12 months. Thirteen percent and 6% of untreated patients developed urolithiasis after 6 and 12 months respectively. The data suggest that HU, like IH, is associated with hematuria. Furthermore, recognition of this association may prevent unnecessary, and in some cases, invasive diagnostic manoeuvres.
