Nonoliguric renal failure after transurethral prostatic resection

Six cases of acute nonoliguric renal failure following transurethral prostatectomy were studied. This condition usually has a milder clinical course than the oliguric type; but some patients will need dialysis and fatalities can occur. Although it is relatively rare, every urologist shoud be aware of the entity. The first clue is usually increasing azotemia despite a normal or increased urine output.
