The "Garganta" used by Hollows in Hueco Mundo to enter the Human World or Soul Society was an instinctive use of a Hollow's spatial powers.
By analyzing the spatial power of the Garganta, Urahara Kisuke had managed to create a Senkaimon. He truly deserved his reputation as the most intelligent man among the Soul Reapers.
Because the Senkaimon Urahara Kisuke had created was essentially a "smuggling route," its safety could not be guaranteed. While passing through the spatial passage, they might encounter spatial storms or temporal turbulence like the Gokuto.

What a cautious fellow...
Urahara Kisuke was slightly startled.
The passage within this Senkaimon had deliberately been left unfinished by Urahara
