title: Ceftazidime concentrations in renal cysts.
abstract: Levels of ceftazidime (CAZ) in uninfected renal cysts of 25 patients were investigated. Seventeen patients received 2 g CAZ about 140 min prior to puncture of the cysts (group I), and eight patients were treated with 2 x 2 g CAZ one day before, and with a further dose of 2 g 2 h prior to puncture (group II). In eight cases (two of group I and six of group II) the concentration of the cyst fluid was also assessed at 4 h and 6 h after completion of the CAZ infusion. In group I, CAZ concentrations were 0.5 to 1.13, micrograms ml-1, mean 0.71; in group II CAZ concentrations were 3.6 to 6.7 micrograms ml-1, mean 5.55. At 4 h and 6 h after infusion the mean cyst concentrations were 4.4 and 2.9 micrograms ml-1, respectively.
