EAU and AUA recommendations based on renal stone size and location.

Anatomical Location in Collecting System	Stone Size	Type of Intervention (EAU)	Type of Intervention (AUA)
Upper/middle calyces/renal pelvis	<10 mm	1. SWL or URS (first line) 2. PCNL (second line)	SWL or URS
	10–20 mm	PCNL/URS or SWL	SWL or URS
	>20 mm	1. PCNL (first line) 2. URS or SWL (second line)	1. PCNL (first line) 2. URS or SWL (second line)
Lower pole	<10 mm	1. SWL or URS (first line) 2. PCNL (second line)	SWL or URS
	10–20 mm	SWL or URS/PCNL (favourable factors for SWL) PCNL/URS as first line, SWL as second line (unfavourable factors for SWL)	1. PCNL/URS (first line) 2. SWL (second line)
	>20 mm	1. PCNL (first line) 2. URS or SWL (second line)	1. PCNL (first line) 2. URS or SWL (second line)

SWL—shockwave lithotripsy, URS—ureteroscopy, PCNL—percutaneous neprolithotomy.
