Owing to technological advances, flexible URS has expanded its indications to include the stones in kidney [].The indication of flexible URS for renal stones is the stones less than 15 mm which do not respond to SWL [].The one of the advantages of flexible URS is the possibility of treating renal and ureteral stones in the same patient in a … In 1976 Shockwave lithotripsy (SWL) and ureteroscopy (URS), perfected over the past decades, together with PCNL, make up the three main surgeries used for stone removal.The straightforward answer is that large kidney stones (greater than 2 cm or 1 inch) are best treated by PCNL as URS and SWL often fail to remove all the stone material leaving behind residual fragments. Compared to those kept overnight, patients selected for “ambulatory” PCNL tend to be healthier, have less complex stone disease, and an uncomplicated operation Approximately 13% of patients present to emergency departments within a month after surgery The risk of developing a post-operative infection following PCNL ranges from 2.5 – 20%.

They start small, but they can grow bigger as more minerals stick to them.

Surgeons who favor this approach say that stone free rates and overall complications are similar to prone positions, but the supine approach is faster – easier positioning, and may also lead to fewer postoperative fever events The most critical step of the procedure is gaining access to the kidney.
