Measurements were recorded during 313 orchidopexies to assess the rela
tive 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 o
f the lateral bands is an essential step to achieve a successful orchi
dopexy.
