title: [Orienting studies of the formaldehyde residue in urologic instruments following sterilization with formaldehyde gas].
abstract: At an orientating investigation the formaldehyde residue at catheters and tubing was defined after formaldehyde gas sterilisation and a varying dependence of the residue of the concentration of the agent solution, the sterilisation time and the tube resp. catheter material was found. The formaldehyde residues lay in the region of micrograms/cm2. They are higher as in the judgement of the equipment producer. The necessity of the investigation of toxicological importance of the residue is mentioned.
