The objective of this research is to investigate the surgical outcomes of minimally invasive percutaneous nephrolithotomy(MPCNL) and retrograde intrarenal surgery (RIRS)for patients with renal stone larger than 1cm.
It is pointed out that there is the disadvantage of conventional PCNL technique which showed dramatic decrease in Hb and renal damage even though it has some advantages of a short operation time and a high stone-free rate. MPCNL and RIRS has recently been considered as very efficacious methods.

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.
Time frame: postoperative 1 month
pain
Visual analogue scale will be measured: 0 (no pain) -\> 10 (the most worst pain ever experienced)
Time frame: postoperative 1 day
hemoglobin drop
preoperative Hb level - Hb level of immediate postoperative 1 day
Time frame: postoperative 1 day
occurrence of complications
occurrence of stricture in non-contrast CT scan history taking of hematuria or fever
Time frame: postoperative 1 day, and the postop 1month at OPD
hospital stay
calculation of days of hospital stay
Time frame: postoperative 1 month
