Learning objectives
- We review the indications for and contraindications to percutaneous nephrolithotripsy (PNL)
- We discuss the importance of multimodality imaging in planning the operative approach
- We review the necessary patient preparation,
positioning and access site planning using fluoroscopy and ultrasound prior to PNL
- We describe standard percutaneous access techniques and discuss more advanced techniques employed in complex cases of urolithiasis such as combined calyceal and ureteral calculi,
calyceal diverticula and renal anatomical variants such as horseshoe kidneys,
duplex collecting systems and uretero-pelvic junction obstruction
- We discuss post-procedure care and patient management including post-procedure imaging,
stent placement and potential complications
- We highlight the importance of close interaction between the radiologist and urologist in optimizing stone clearance rates in patients undergoing PNL
