As far as I know, “self-hydraulic urethral dilation,” as mentioned by Raimund Schmitz, has not been validated in scientific studies, and, crucially, the question is whether the pressure exerted by the bladder is sufficiently high to help expand the fibrosing tissue of a scarred urethra.
I am not aware of any scientific studies that have investigated the transplantation of embryonic umbilical cord vein, as mentioned by Professor Klippel, and I am sure it plays no real part in clinical routine. Such a procedure would surely have to be investigated in clinical studies.
Stoffregen has contributed interesting insights into the topic of the history of treatment for urethral strictures, which reminds us how long this topic has been the subject of discussion in medicine.
