Abstract
Summary— In 14 dogs, using a modified Davis technique, excised segments of ureters were replaced by free, partial‐thickness bladder grafts vascularised by omentum. Eight of the 14 dogs had satisfactory radiological appearances of the operated upper tracts at 12 months, and 9 of the 14 were unobstructed urodynamically at this time. Graft segments did not appear to contract. Urothelial and smooth muscle regeneration was observed.
