Abstract
Introduction The clinical and experimental repair of long ureteral defects remains a challenging problem. An ideal ureteral substitute should simulate the form and function of the normal ureter. The use of Fallopian tube as a conduit to replace ureter is suggested by the following features: (1) The anatomic proximity of the two organs. (2) The expendability of Fallopian tube. (3) The fact that both possess a mucosal lining and a muscular wall with peristaltic activity. (4) The manipulable blood supply of the tube, which need not be compromised when used as a pedicle graft to replace a segment of ureter. (5) The avoidance of problems of antigenicity and foreign-body reaction when an autogenous graft, rather than a homologous structure or an inorganic tube, is substituted for ureter. This report is concerned with the experimental reconstruction of long ureteral defects by the use of substitute Fallopian tube pedicle grafts. Method Nineteen
