The role of common urinary constituents in the precipitation of ammonium acid urate.

A high proportion of the inhibitory activity shown by urine toward precipitation of ammonium acid urate is ultrafilterable and most of this can be accounted for by the common, low molecular weight components of urine. The individual inhibitory effects of sodium chloride, sodium sulphate, potassium chloride, calcium chloride, magnesium sulphate, sodium dihydrogen phosphate, sodium pyrophosphate, citric acid, hippuric acid, creatinine and urea upon the precipitation of ammonium acid urate have been quantified in an aqueous test system.

Factors affecting the solubility of ammonium acid urate.

Evidence is presented that sodium acid urate exists in aqueous solution in a non-colloidal state. The levels of ammonium and urate ions required to precipitate ammonium acid urate have been established for some aqueous media. The effect of pH on the formation product of ammonium acid urate is described. Evidence is presented that there is no epitaxial relationship between this salt and calcium oxalate monohydrate.

Orthopaedic problems of renal transplantation.

One in six patients receiving renal transplants has orthopaedic problems. Osteoporosis with accompanying fractures is common, as is avascular necrosis of the hips, knees, and other bones. Immunosuppressive therapy with steroids is implicated and its mode of action discussed. No means of prophylasix is known. If treated conservatively, aseptic necrosis of bone is much more disabling than is commonly believed as judged by the critical assessment technique of Charnley. The authors therefore recommend that a surgical approach should be adopted whenever possible.

The diagnosis and treatment of lymphocoeles associated with renal transplantation. A report of 6 cases and a review of the literature.

Six patients have developed a lymphocoele after renal transplantation, an incidence of 4%. A lymphocoele should be suspected in a patient who develops a rising creatinine with a pelvic mass or pressure effects on the pelvic veins 1 or more months after operation. The diagnosis is confirmed by intravenous urography, venography and ultrasonography: the use of the latter as a diagnostic measure is recommended. Treatment is by marsupialisation into the peritoneum or external drainage with breakdown of all loculi. Aspiration is unsatisfactory.

The endemic bladder stones of Indonesia---epidemiology and clinical features.

Bladder stone is a relatively common disease of childhood in West Sumatra with an incidence of 8.3/100,000 population per year. We have studied 87 cases with a peak age of onset of 2-4 years and a male/female ratio of 12:1. The majority of these are from poor families with a diet low in protein and phosphate. Diarrhoea is common. The composition of the stones is primarily ammonium acid urate. Patients with sterile urine have shown significantly higher levels of urinary ammonia than controls, and only approximately 50% of patients' urine were infected. This is consistent with excretion of a high acid load, due both to an acidogenic rice diet and diarrhoea, combined with a low level of phosphate. This condition was once endemic in Europe but is now confined to a belt of countries from the Balkans through Asia.
