How to set variable in store procedure also pass its value to another statement using SQL Server

I have a stored Procedure 

CREATE PROCEDURE DeleteDataByUserID
@UserID int
as
BEGIN

delete from staffskills where StaffProfileID=(select s.StaffProfileID from staffprofiles s where s.userid=@UserID)
delete from staffLanguages where StaffProfileID=(select s.StaffProfileID from staffprofiles s where s.userid=@UserID)
delete from staffLocations where StaffProfileID=(select s.StaffProfileID from staffprofiles s where s.userid=@UserID)

END

Now I want Code Like 

CREATE PROCEDURE DeleteDataByUserID
@UserID int
as
BEGIN
int staffID=select s.StaffProfileID from staffprofiles s where s.userid=@UserID
delete from staffskills where StaffProfileID=staffID
delete from staffLanguages where StaffProfileID=staffID
delete from staffLocations where StaffProfileID=staffID

END

In case of first one for every statement i am going to db and fetching staffid everytime.

How to over come this one .
