NCT02648386

Brief Summary

Erectile dysfunction (ED) is one of the commonest complications in men after rectal cancer treatment. The purpose of this study is to assess the safety and efficacy of autologous bone marrow mononuclear cells (BMMCs) or allogeneic human umbilical cord-derived mesenchymal stem cells (HUC-MSCs) combined with NeuroRegen scaffold transplantation in men with erectile dysfunction after rectal cancer treatment.

Biological: NeuroRegen scaffold/HUC-MSCs transplantation

Interventions

Completely resected rectal tumor.

Laparoscopic surgery

After completely resected rectal tumor, exposed pelvic autonomic nerves, and then transplanted NeuroRegen scaffold to the nerve.

NeuroRegen scaffold transplantation

Completely resected rectal tumor, exposed pelvic autonomic nerves, and then transplanted NeuroRegen scaffold loaded with 5 million bone marrow mononuclear cells to the nerve.

NeuroRegen scaffold/BMMCs transplantation

Completely resected rectal tumor, exposed pelvic autonomic nerves, and then transplanted NeuroRegen scaffold loaded with 5 million human umbilical cord mesenchymal cells to the nerve.
