A total of 270 muscles, 45 of each of the six individual muscles studied (the sartorius m., the gracilis m., the semitendinous m., the semimembranous m., the greatest gluteal m., the internal obturator m.) were followed up with the aim of evaluating their length parameters and blood and nerve supply. The aim of the study has been to choose the muscle most suitable for transposition and reconstruction of the neosphincter. From the point of view of their anatomy, the internal obturator muscle has been found the most suitable for the purpose.
