[Parenteral feeding after ureterosigmoidostomy: nitron balance, free plasma amino acids and state of proteins].

The postoperative protein metabolism of 11 patients who had required either a colon conduit or ureterosigmoidostomy urinary diversion was examined. From the 3rd to 10th postoperative day day, each patient received a standard parenteral alimentation (100 g amino acids and 2000 kcal/24 h). Nitrogen balance, plasma level of the free amino acids, and the C3c-, C4-complement and transferrin fraction in plasma were determined regularly. The results showed that this substitution therapy succeeded in avoiding serious alterations in the parameters measured.
