BACKGROUND: There are special requirements for draining a pouch, e.g. length, flexibility and ability to drain highly viscous urine. METHODS: We checked in vitro the flow time of pure and synthetic urine thickened with hydroxyethylcellulose (0.125% and 0.250%, HEC) on selected catheters. RESULTS: We found for SpeediCath Compact Male (SCCM) as a CH12 catheter the shortest flow times for undiluted and urine thickened with 0.125% and for SafetyCath Plus for urine thickened with 0.250%. For catheters with CH14 we found significantly shorter flow times for all tested solutions. The flow time does not depend on amount and area of the catheter eyes; we found no difference in the flow time for 4-eye (MobiStom) and 2-eye catheters.
