Segmental replacement of the ureter using Sparks' mandrils. An experimental study.
Segmental ureteral replacement with free autogenous fibroelastic Dacron tube grafts in three dogs was unsuccessful during preliminary trials. However, a proliferation of urothelium, smooth muscle, and blood vessels throughout the length of the grafts was demonstrated, providing an encouraging potential for further investigations. Technical refinements are suggested that may provide for improved success with experimental ureteral replacement.
