title: [Percutaneous surgery in renal lithiasis. Current indications].
abstract: The indiscriminate use of extracorporeal shock waves in the treatment of urinary calculi has changed the place of percutaneous surgery in the treatment of renal lithiasis. The authors analyse current indications of PCN highlighting stone size. In their view, calculi greater than 2 cm warrant treatment by PCN since only 15-20% of patients are completely stone-free following a single session of ESWL. Attention is focussed on the staghorn calculus and the percutaneous approach. They describe the difficulty encountered in the fragmentation of the cystine calculus owing to its hardness and discuss the difficulties that may arise when using the percutaneous approach in patients with coexisting renoureteral conditions, in the treatment of lithiasis in children and in the obese patients.
