Outcome Measures

Primary Outcomes (1)

  • The effect of stents on body pain

    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.

    Two weeks after stents inserting and two weeks after stents removing

Secondary Outcomes (5)

  • The effect of stents on stone-free rate

    Two weeks after stents inserting and two weeks after stents removing

  • The effect of stents on urinary symptoms

    Two weeks after stents inserting and two weeks after stents removing

  • The effect of stents on daily activities and psychological well-being

    Two weeks after stents inserting and two weeks after stents removing

  • The effect of stents on clinical presentation

    Two weeks after stents inserting and two weeks after stents removing

  • The effect of the stent on learning

    Two weeks after stents inserting and two weeks after stents removing

Study Arms (2)
