Predictive value of bedside effective renal plasma flow for renal recovery in severe XXXX .

Single injection, single blood sample, effective renal plasma flow (ERPF) estimated by 131I-orthoiodohippurate can be performed accurately and conveniently without urine collection at the bedside. The purpose of this study was to determine if ERPF early in the course of severe @entity810 ( @entity810 ) predicts recovery of renal function in hemodynamically stable @entity1 . Over 18 months, ERPF was determined in 33 such @entity1 with @entity810 in whom an etiologic diagnosis could be established. Eight @entity1 died within 2 months of onset and while on dialysis, did not have an autopsy, and were not considered further. Six @entity1 (Group A) either remained on dialysis after at least 6 months follow-up or had irreversible @entity8 at autopsy. In Group B (19 @entity1 , 13 of whom were dialyzed), serum @entity1011 returned to less than 2.0 mg/dL (n = 16) or was decreasing without dialysis. Peak serum @entity1011 (Group A 11.2 +/- 1.4; Group B 10.1 +/- 1.3 mg/dL) did not differ between groups. @entity1458 was present in 75% of Group A @entity1 and in 25% of Group B @entity1 . Initial ERPFs differed (p less than 0.001) between Group A (90 +/- 11) and Group B (204 +/- 20 mL/min). Initial ERPF was greater than 125 mL/min in 15 Group B @entity1 but in no Group A @entity1 ; the false-positive rate was 21% and the false-negative rate was 0%.(ABSTRACT TRUNCATED AT 250 WORDS)
