Due to the anatomic characteristics of the lower calyx, lower pole stones are difficult to be eliminated through the ureter, even if the stones had been fragmented. Retrograde intrarenal surgery (RIRS) can be used to deal with lower pole stones of 1.0-2.0 cm, while percutaneous nephrolithotripsy (PCNL) is mainly used to deal with lower pole stones with larger diameter or when RIRS failed to resolve the stone. This study was conducted to compare mini PCNL and retrograde intrarenal surgery (RIRS) for the management of lower pole kidney stones in terms of efficacy.

| Mini-PCNL | Procedure | Mini-PCNL will done as follows. A 6 Fr ureteral catheter will be introduced through cystoscopy and dye will be instilled to opacify the pelvicalyceal system. After elaborating the calyceal system through fluoroscopy, selective calyceal will be punctured and tract will be dilated using 16 F sheath. Miniature nephroscope 14 Fr will be then introduced and stones will be fragmented by holmium: YAG laser. Afterwards the collecting system will be examined through nephroscope and fluoroscopic confirmation will be done to ensure complete stone clearance. In all the cases, 6 Fr 24 cm DJ stent will be placed and if remained uneventful, the patient will be discharged on postoperative day 2 with oral antibiotics. |

| RIRS | Procedure | RIRS will be performed as follows. In this procedure a double J stent will be placed to dilate the calyceal system 2 weeks prior the surgery. During the procedure, cystoscopy will be done, and 0.035-inch guide wire will be placed in the pelvi-calyceal system. Ureteric access sheath of 12 Fr will be placed and with the help of digital polyscope the stone will be fragmented using Holmium: YAG laser using 220 μm fiber. DJ stent 6F 24 cm will be placed in all the cases. In uneventful surgery patient will be discharged on postoperative day 1 with oral antibiotics |
