Ex Input:
Question: Do empirical aminoglycosides for peritonitis affect residual renal function?
Answer: In our patients, there was no evidence of an accelerated decline in RRF when using an empirical regimen containing aminoglycosides for peritonitis. Because there are few data to contradict this finding, we recommend the continued use of these drugs in peritonitis regimens, even in patients with significant RRF.

Ex Output:
no
