Kidney function of pyelonephritis patients with impaired renal function treated with mezlocillin.

Ten patients with pyelonephritis and impaired renal function were treated with 2.0 g mezlocillin (Baypen) 8-hourly. They all recovered from urinary tract infection and showed a distinct improvement of their kidney function measured by blood urea nitrogen, serum creatinine and creatinine clearance. No side effects were seen and the blood coagulation remained within normal limits. An overview of the literature on urinary tract infections treated in patients with impaired kidney function is given.
