To the Editor:—
The drainage of ureteral catheters into sterile bottles and receptacles has been a traditional but most unsatisfactory practice for years. The use of rubber tubing for drainage has not been practical because the lumen of a small tube is predisposed to clogging by urine and its constituents, whereas adaptors for larger tubing are usually bulky and unsatisfactory. This problem has been met satisfactorily by the use of discarded intravenous polyethylene tubing. One end of the tube has already been designed to fit perfectly into the hub of a needle (see illustration). The lumen of this plastic tube is much larger than that of a rubber tube of comparable size, and its smooth surface lessens the tendency of blood and urine precipitates to adhere to its walls. Sterilization is carried out by cleansing with a detergent, flushing with saline solution, and soaking in a 1:500 solution of benzalkonium
