RAPIDLY REVERSIBLE ACUTE-RENAL-FAILURE FROM URETERAL OBSTRUCTION IN PREGNANCY

We report a case of acute renal failure due to bilateral ureteral obst ruction that rapidly resolved after delivery, Acute renal failure seco ndary to bilateral ureteral obstruction is rare; to our knowledge, onl y 18 cases have been reported in the English literature, Review of the se cases reveals that twin pregnancies, polyhydramnios, and obstructio n of the solitary kidney seem to increase the risk of obstructive rena l failure. Measures including induced delivery, amniocentesis, and ins ertion of ureteral stents or nephrostomy tubes undertaken to relieve t he ureteral obstruction usually lead to rapid improvement in urine flo w and renal function, Acute renal failure secondary to bilateral urete ral obstruction is a rare but reversible complication of pregnancy.
