If you were tasked with implanting silicone gel testicular prostheses in a beagle dog, which would be the more effective procedure, “under the tunica albuginea” or “under the tunica vaginalis”?
Tong-li Hao (Department of Urology, General Hospital of Chinese People’s Liberation Army, Beijing, China) and
Peng Chen (Department of Electromagnetics and Laser Biology, Radiation Medicine Institute, Academy of Military Medical Sciences, Beijing, China) recently performed a study to find out. For background, the team remind us that :
“Implantation of testis prosthesis under the tunica albuginea has been considered to be the standard method in the most of the reports. However, postoperative scrotal appearance, the mobilization and the palpitation of the prosthesis are not always satisfactory to all the patients.”
Their comparative experimental tests with nine beagles indicated :
“Prostheses implanted under the tunica vaginalis showed a more satisfying mobilization and palpation than those implanted under the tunica albuginea.”
But noting however :
