Inclusion criteria

  1. Diagnosed as upper urinary calculi by B-ultrasound, kidney and upper bladder (KUB), intravenous urogram (IVU) or computerized tomography (CT) before surgery with the ages between 20 and 70 years.
  2. Having ureteral residual fragments post URL and the diameter more than 5mm.
  3. The lithotripsy went smoothly with expected outcomes and without any ureteral perforation, mucous exfoliation, kidney or bladder injury, serious bleeding or any other complications.
  4. Willing and able to participate in this study and comply with all scheduled visits, treatment plans and complete the clinical observations.

Exclusion criteria

Exclusion Criteria:

  1. Pregnancy, severe diabetes, or renal insufficiency.
  2. Ureteral stricture and lower urinary tract obstruction.
  3. Concomitant treatment with α1-receptor antagonists, or Chinese traditional medicines who can be used to relieve stranguria and expel stone, or any other treatment that might interference the efficacy evaluation.
  4. Unwilling or unable to comply with the administration regimen described in the protocol, or having an incomplete profile, hence their efficacy and safety couldn't be evaluated.
  5. Severe adverse events and need to withdraw from the study.

What researchers measure

Primary outcomes

  1. the stone expulsion time, stone-free time

    The diminishing or vanishing of residual fragment identified by post-surgery B-ultrasound or KUB could suggest a residual fragment expulsion. Evaluation with KUB showing the shadow of calculi disappearing completely followed by a confirmation using CT could suggest a residual fragment clearance.

    Time frame: From baseline to 12 weeks of treatment

Secondary outcomes

  1. the stone expulsion rate and stone-free rate.

    The diminishing or vanishing of residual fragment identified by post-surgery B-ultrasound or KUB could suggest a residual fragment expulsion. Evaluation with KUB showing the shadow of calculi disappearing completely followed by a confirmation using CT could suggest a residual fragment clearance.

    Time frame: From baseline to 12 weeks of treatment
