Orchidopexy: the relative importance of each step of mobilisation.

Measurements were recorded during 313 orchidopexies to assess the relative importance of each step of the procedure. Division of the sac or processus accounts for 60% of the increased length of the cord (1.453 cm), whilst the remaining 40% (1.048 cm) of the total net gain (2.501 cm) is due to dissection within the internal inguinal ring. Division of the lateral bands is an essential step to achieve a successful orchidopexy.
