Primary outcome measure(s)
- The effect of stents on body pain — Two weeks after stents inserting and two weeks after stents removing
Inquire whether the child has experienced body pain, especially lumbar pain after the insert or removal of the stent. If yes, assign a value of 1; if no, assign a value of 0. The higher the score, the worse the stent is in terms of relieving lumbar pain.
