Reflex anuria and uremia from unilateral ureteral obstruction.

A 59-year-old man had anuria of 32 hours' duration that was associated with unilateral calculous ureteral obstruction. Retrograde pyelography showed a normal contralateral collecting system. Initial technetium pentetate (DTPA) scanning showed diminished uptake of radioactivity by the unobstructed kidney compared with the obstructed kidney, whereas a follow-up study, after relief of ureteral obstruction, showed a reversal of this pattern. Previously reported cases of "reflex anuria" are reviewed along with the relevant experimental literature. Vascular or ureteral spasm related in part to abnormality of the autonomic nervous system may underlie this rare entity.

Changes in erythrocyte membrane ouabain-sensitive adenosine triphosphatase after renal transplantation.

1. Intracellular electrolytes, and erythrocyte membrane adenosine triphosphatase (ATPase) activity, was studied in twenty patients after renal transplantation. 2. The mean ouabain-sensitive ATPase activity in the erythrocyte membranes of the transplant patients was 122 nmol of inorganic phosphorus (Pi) h-1 mg of tissue-1 (SEM 14), compared with 62 nmol of Pi h-1 mg of tissue-1 (SEM 8) in a group of paired, healthy controls. 3. The increase in ouabain-sensitive ATPase was most marked in the 4 months after transplantation. However, a significant increase in ouabain-sensitive ATPase persisted for more than 8 months after transplantation. 4. This increase in ouabain-sensitive ATPase was associated with a decrease in intracellular sodium in the erythrocytes of the transplant patients.
