Neoseminal vesicle created from retained mullerian duct to preserve the vas in male infants.

Patients with retained mullerian ducts who have a predominantly male phenotype must undergo removal of the mullerian structure in addition to preservation of male structures. Often the vas conjoins with the vaginal wall. Whereas formerly we divided the vas from the mullerian structures, we now attempt to preserve the vas to maintain as much testicular function as possible by creation of a neoseminal vesicle. This procedure can be done separately or can accompany hypospadias reconstruction.
