An obstructed infected system

A hypothetical patient has fever, flank pain, reduced blood pressure and imaging showing a ureteral stone with an obstructed collecting system. Urine and blood sampling are being arranged without delaying urgent care. A colleague proposes waiting for definitive culture identification before responding, while another wants immediate elective-style laser stone fragmentation as the only intervention. The team needs to distinguish resuscitation, antimicrobial treatment and drainage from the later definitive management of the calculus. No drug dose, drainage route or operative technique is specified in the case because those require the actual patient, anatomy, available expertise and current local protocol. The task concerns priorities and mechanism, not a stand-alone procedural instruction.
