Systemic inflammatory response syndrome (SIRS) is a severe complication of acute obstructive pyelonephritis (AOP) that is caused by ureteral stones before urosepsis develops. Ureteral stone-related AOP is a urological emergency because it can cause a rapid loss of renal function and quickly develop to urosepsis or even septic shock within hours [Percutaneous nephrostomy (PCN) and retrograde ureteral stent insertion (RUSI) are the two most commonly used emergency drainage methods, and the more effective method remains controversial.
