Abstract

Aim

We aimed to study the clinical profile, prognostic factors, and the 6-month outcome of patients with emphysematous pyelonephritis (EPN)

Methods

All patients admitted with a diagnosis of emphysematous pyelonephritis between January 2001 and July 2007 were included.

Results

Overall 19 cases were diagnosed to have emphysematous pyelonephritis. There were 16 females and three males. Fourteen cases had type 2 diabetes mellitus. Fourteen cases had unilateral involvement and five had bilateral involvement. Eleven cases were classified as having class 1 or 2 disease and eight cases had class 3 and 4 disease. E. coli was the most common organism cultured (68.4%). Five cases underwent percutaneous drainage of the collecting system and three cases had nephrectomy of which 10.5% (two with advanced disease) expired. Shock at admission (p = 0.03), serum creatinine >5.0 mg/dl (p = 0.035) and DIC (p = 0.017) were independent poor prognostic factors. There was no difference in the prognosis between patients who had ≥2 or <2 poor prognostic factors (p = 0.16). However, prognosis was not related to disease class, unilateral vs. bilateral involvement, sepsis or the age of the patient. At 6 months, two patients were on maintenance hemodialysis.

Conclusions

In cases of EPN, shock, serum creatinine >5.0 mg/dl and DIC at admission are poor prognostic factors. Larger prospective studies are needed to confirm our findings.
