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.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| RIRS (retrograde intrarenal surgery) | Active Comparator | Use of flexible ureteroscopy to access and remove renal stones without percutaneous nephrostomy tract |
|
| 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 |

| Measure | Description | Time Frame |
|---|---|---|
| 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 |
| Measure | Description | Time Frame |
|---|---|---|
| pain | Visual analogue scale will be measured: 0 (no pain) -> 10 (the most worst pain ever experienced) | postoperative 1 day |
| hemoglobin drop | preoperative Hb level - Hb level of immediate postoperative 1 day |
