Introduction: PCNL has been widely established as a standard technique for treatment of renal stones. Now further technological advancement has made it possible to manage the renal stones by decreasing the tract size to micro levels. Materials and Methods: We demonstarates the technique of micro PCNL which employs use of special set of micro-instruments which is a three part 5.5 Fr optical needle housing 0.8mm flexible fibreoptic telescope for direct visualisation during puncture.As in standard PCNL,cystoscopy and ureteric catheter is passed on operating side and patient turned to prone position. After puncturing the stone bearing calyx,three way connector is attached to micro needle through which irrigations,telescope and laser fibre is introduced for fragmentation of stone. Another 8 Fr sheath is also used in case lithoclast is used to fragment the stone.After complete clearance DJ is placed and no nephrostomy kept. conclusion: Micro-PCNL is a new technological advancement with potential of reducing morbidity associated with conventional PCNL in selective cases.
