Effect of herb medicines for urolithiasis on urinary oxalate excretion in rats.

The oxalate content in choreito and urocalun, both herb medicines, is minimal, and their contents of Ca, Mg, and P are also small. A rat experiment was performed to clarify their effect on oxalate excretion. They did not seem to have any adverse effect on urinary oxalate excretion. They had no diuretic effect and did not promote urinary oxalate excretion in rats. Therefore, they can be used in stone-formers for long periods.

Renal autotransplantation for localized amyloidosis of the ureter.

Localized amyloidosis of the ureter is a relatively rare disease, causing at times ureteral stenosis with hydronephrosis and renal function impairment to various extent. Although it is not malignant nearly all reported cases have been treated by nephroureterectomy because it is clinically difficult to differentiate this entity from ureteral malignancy. We report a case in which the ipsilateral kidney was salvaged successfully by renal autotransplantation. To the best of our knowledge, this is the first case reported of renal autotransplantation for localized amyloidosis of the ureter in the English literature. We suggest that renal autotransplantation be considered in cases of localized ureteral amyloidosis.

Xanthogranulomatous pyelonephritis in childhood: case report and review of English and Japanese literature.

Xanthogranulomatous pyelonephritis is an uncommon disease that is usually seen in middle-aged women and is much rarer in children. We report a case of diffuse xanthogranulomatous pyelonephritis in a 3-year-old boy who had a nonfunctioning hydronephrotic right kidney on an excretory urogram. A review of the English and Japanese literature on xanthogranulomatous pyelonephritis in childhood revealed 2 remarkable differences regarding the incidence of sex and radiological findings. The majority of patients were girls in the English literature, whereas the opposite sex was seen in the majority of cases in Japan. The involved kidney was functioning on an excretory urogram in the majority of cases reported in the English literature, however, in all cases from Japan the involved kidney was non functioning. These findings further support the newer concept that xanthogranulomatous pyelonephritis in childhood exists in focal as well as diffuse forms.

A case of multiple extra-adrenal pheochromocytomas.

A 22 year old man with two extra-adrenal pheochromocytomas located in the mediastinum and in the pelvis is presented. We believe this is the first report in Japan of extra-adrenal multiple pheochromocytomas in adult located in the two distant places.

Plasma erythropoietin activity before and after renal homotransplantation in humans.

Plasma erythropoietin levels were determined by Keighley's method to study the changes in erythropoiesis before and after human renal homotransplantation. Results. Erythropoietin titres in pre-transplant patients were low, while they returned to normal after successful renal transplantation. In acute rejection they were significantly high. After its reversal normal levels of erythropoietin were obtained in accordance with a normalization of the graft functions. Reticulocyte counts paralleled with erythropoietin values. Conclusion. High levels of plasma erythropoietin contribute to the diagnosis of acute rejection. Normalization of the plasma erythropoietin levels after the acute rejection could be regarded as an indication for good function of the graft. The grafted kidneys seem to function in producing erythropoietin.
