As far as I know, the penile urethra is used as part of the vaginal lining at dr. Schaff in Munich, Germany and at dr. Djinovic in Belgrade, Serbia. Others may have experimented with that in the past, by no longer do it. Dr. Brassard in Montreal, Canada and dr. Bowers in California use the penile urethra as the lining of the inner part of the labia minora, but not in the vaginal canal. All other big-name surgeons just throw it away.
I do not know of any surgeon who uses glans material inside the vagina nowadays. It is sometimes mentioned as part of the GRS history - 1960s, 1970s. That was back in time when many surgeons (all of them male) were not educated about the importance of the clitoris and only focused on the vaginal canal.
