Percutaneous nephrolithotomy (PCNL) is a minimally-invasive procedure to remove stones from the kidney by a small puncture wound (up to about 1 cm) through the skin. It is most suitable to remove stones of more than 2 cm in size and which are present near the pelvic region.
Laser lithotripsy (LL) has been evaluated against Extracorporeal Shock Wave lithotripsy (ESWL), finding both to be safe and effective. [3] [4] ESWL may be safer for small stones (<10 mm), but less effective for 10–20 mm stones. [3]
Percutaneous nephrolithotomy or, rarely, anatrophic nephrolithotomy, is the treatment of choice for large or complicated stones (such as calyceal staghorn calculi) or stones that cannot be extracted using less invasive procedures. [56] [7]
Surgery was the only method to remove stones too large to pass until French surgeon and urologist Jean Civiale in 1832 invented a surgical instrument (the lithotrite) to crush stones inside the urinary bladder without having to open the abdomen.
Postoperative wounds are those wounds acquired during surgical procedures. Postoperative wound healing occurs after surgery and normally follows distinct bodily reactions: the inflammatory response, the proliferation of cells and tissues that initiate healing, and the final remodeling.
A nephrostomy or percutaneous nephrostomy is an artificial opening created between the kidney and the skin which allows for the urinary diversion directly from the upper part of the urinary system (renal pelvis). [2] It is an interventional radiology/surgical procedure in which the renal pelvis is punctured whilst using imaging as guidance.

Dr. Janak D. Desai is an Indian urologist (M.S.; M.Ch; FRCS) best known for developing the technique of Ultra-Mini PCNL [1] which involves kidney stone removal by a minimally invasive key-hole technique which reduces the blood loss, pain and hospitalization for a patient suffering from kidney stone.
