Replacement of ureteric segments by intubated neo-ureterotomies (modified Davis technique) using autologous bladder and omentum in dogs.
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.
