A urinary tract stone that is causing obstruction while the patient presents with signs of urinary tract infection — including sepsis — and/or anuria.
The obstructed kidney with all signs of urinary tract infection (UTI) and/or anuria is a urological emergency. The co-occurrence of obstruction with active infection or cessation of urine output demands immediate clinical action.
Management requires urgent decompression of the collecting system — followed immediately by antimicrobial therapy, with escalation to intensive care when the clinical picture demands it. Definitive stone treatment is deferred until the acute phase is fully resolved.
Resolution of sepsis.
