Emphysematous pyelonephritis (class IIIa) managed with antibiotics alone

Area of Science:

• Nephrology
• Infectious Diseases
• Radiology

Background:

• Emphysematous pyelonephritis is a severe necrotizing infection of the kidney.
• Class IIIa emphysematous pyelonephritis typically requires aggressive intervention like nephrectomy.

Observation:

• A 54-year-old male with diabetes presented with symptoms suggestive of acute pyelonephritis.
• Imaging revealed extensive emphysematous pyelonephritis (class IIIa) involving the left kidney and perinephric space.
• The patient refused surgery or percutaneous drainage, opting for medical management.

Findings:

• The patient received empirical antibiotics and insulin for uncontrolled diabetes.
• Remarkable clinical improvement was observed with conservative management alone.
• Follow-up ultrasound after 4 months showed normal renal morphology.

Implications:

• This case suggests that conservative management may be a viable option for select patients with class IIIa emphysematous pyelonephritis.
• It highlights the potential for successful non-surgical treatment in specific clinical scenarios.
• Further research is warranted to establish guidelines for conservative management of this severe condition.
