Asymptomatic emphysematous pyelitis-a rare clinical entity. A 62-year-old asymptomatic woman with diabetes was referred to the urology department from nephrology due to deterioration in renal function with accompanied right-sided hydronephrosis on ultrasound. CT imaging subsequently revealed a right-sided staghorn calculus and a significant volume of gas in the right collecting system from the kidney to the distal ureter, in keeping with emphysematous pyelitis. She was admitted and managed with antibiotics and insertion of right nephrostomy in the first instance, followed by percutaneous nephrolithotomy to definitively manage the stone. The patient remained asymptomatic throughout the process.
