Abstract
A method for the sterilizing filtration of Renacidin, a urologic irrigating solution, was evaluated. Renacidin irrigation was prepared and sterilized by microporous membrane filtration. A sterilizing membrane filtration apparatus was challenged by inoculating a batch of irrigation by inoculating a batch of irrigation solution with Escherichia coli. The sterility of both intentionally contaminated and routinely prepared batches was evaluated. The stability of the solution was monitored by pH measurement, visual examination, maintenance of a vacuum, and absorbance spectrum of a 1:100 dilution in deionized water over a wavelength range from 400 to 200 nm. The time required to prepare three one-liter units was about two hours. No microbial growth was detected in any of the samples. The predicted minimum shelf-life at 10°C was six months. Because the prepared solution contains some unreacted citric acid and bicarbonates, storage at room temperature could produce excessive pressure inside the container from carbon dioxide gas evolution. Refrigerated storage is recommended. This method for the preparation and sterilization of Renacidin irrigation is reasonably expedient, economical, and reliable.
