[Which studies are needed for the prediction of postoperative serum creatinine in unilateral nephrectomy? A retrospective analysis of 136 nephrectomies].

Abstract

Among 136 patients with unilateral nephrectomy between 1985 and 1988 at the Marienhospital Gelsenkirchen the renal function was evaluated in the postoperative course. The serum creatinine value did increase from 88.4 +/- 5.3 mumol/l preoperatively to 168.8 +/- 13.3 mumol/l on the 10th postoperative day. The elevation was significantly higher in patients with more than one associated disease (e.g. diabetes, hypertension). The extent of creatinine elevation could predicated safe by both preoperative creatinine value and isotope renal split function analysis. Therefore, functional isotope examination may not be indicated in patients without impairment of renal function.
