Outcome Measures

Primary Outcomes (1)

  • stone-free rate

    We will check the non-contrast CT scan at postoperative 1month when the patient visit the outpatient department. If the patient does not have any residual stone fragment, it will be reported to 'success.' Otherwise, we will measure the size of each stone of residual fragments.

    postoperative 1 month

Secondary Outcomes (4)

  • pain

    postoperative 1 day

  • hemoglobin drop

    postoperative 1 day

  • occurrence of complications

    postoperative 1 day, and the postop 1month at OPD

  • hospital stay

    postoperative 1 month

Study Arms (2)

RIRS (retrograde intrarenal surgery)

ACTIVE COMPARATOR

Use of flexible ureteroscopy to access and remove renal stones without percutaneous nephrostomy tract

Device: RIRS

MPCNL (mini-perc)

EXPERIMENTAL

A new technique that reduced the size of percutaneous tract to make renal stone into small pieces. Patients will be randomized and assigned to each group at the ratio 1:1

Device: MPCNL
