- Purpose: This study examined the characteristics, current treatment trends, and outcomes of patients with emphysematous pyelonephritis (EPN) in Korea.
Materials andMethods: Two hundred and seventeen patients diagnosed with EPN were evaluated using abdominal computed tomography in 2011-2021 at 15 institutes in Korea. The patients’ demographic and clinical characteristics, treatment modalities, and treatment outcomes were analyzed. The total study period was divided arbitrarily into groups A (2011-2014), B (2015-2017), and C (2018-2021) to analyze the trends in the EPN treatment.
Results: The mean age of the patients was 65.1 years; there were more female patients (74.2%) than male patients. The overall mortality rate was 10.6%. Ninety-five (43.8%), 98 (45.2%), and 24 (11.0%) patients were treated with medical, minimally invasive, and surgical management, respectively; the corresponding mortality rates were 13.7%, 6.1%, and 16.7%. There was no significant change in the proportion of patients treated with medical management over time (group A=46.5%, group B=47.0%, and group C=38.8%). The proportion of patients treated with minimally invasive management gradually increased over time (group A=35.2%; group B=43.9%; group C=55.0%), while those who underwent surgical management decreased gradually over time (group A=18.3%, group B=9.1%, and group C=6.3%). No differences in mortality rates were observed between the groups.
Conclusions: EPN with medical and minimally invasive management had a relatively high treatment success rate, which increased gradually, while surgical management decreased gradually over time in Korea. The mortality rate was relatively lower than that reported in studies published before the 2010s.

Abstract

- Urinary tract infection is responsible for major morbidity and mortality in the patients with the bladder dysfunction. Several factors appear to be responsible for an increased risk of infection in the bladder dysfunction. Significant residual urine, elevated intravesical pressure, frequent exposure to antibiotics and catheter use contribute to an increased risk of symptomatic urinary tract infection. The goals of lower urinary tract management in voiding dysfunction patients include achieving complete bladder emptying, maintenance of low intravesical pressures. Through these measures the aim is to prevent renal damage, while maximizing the patient's quality of life and independence.
