CLOSED DRAINAGE SYSTEM FOR INFANT FEEDING TUBES USED AS URETERAL STENTS MICHAEL J. CHEHVAL, M.D. From the Department of Surgery, Division of Genitourinary Surgery, St. Johns Mercy Medical Center, St. Louis, Missouri

Over the years we have often used 5F and 8F infant feeding tubes to stent ureters in the pediatric patient post ureteral reimplantation and after various other reanastomoses. Drainage has been excellent and migration rare. However, the problem of maintaining a closed system to the urinary collection bag has been diffi-

cult. Most available adapters do not f[~ resulting in leakage and open channels for b ~ teria. In the last two years we have b ~ pleased with the following system which ~ lizes readily available equipment and p r o ~ good, closed drainage.
