Purpose
We have investigated the technical and clinical success of percutaneous catheter drainage (PCD) in retroperitoneal abscesses and factors that may affect the outcome.

Material and methods
The study cohort included 45 patients (17 females and 29 males, with mean age of 56.3 years) that were treated between 2012 and 2020. Forty-seven abscesses were managed with PCD under ultrasonography, computed tomography, or fluoroscopy guidance. Patients’ demographics, lesion locations, predisposing factors, clini­cal presentation, etiology, radiological findings, technical factors, and outcome parameters were presented using exploratory and descriptive statistics.

Results
Abscesses were located in the psoas (n = 25, 55.3%), renal-perirenal (n = 7, 14.8%), and pararenal (n = 14, 29.7%) compartments. The mean preprocedural volume was 263.3 (30-1310) ml. Pain (abdominal and back) (57.4%) and fever (17%) were the most frequent presenting symptoms. The most common predisposing factors were previous surgery (n = 17, 36.1%) and diabetes mellitus (n = 11, 25.5%). Clinical success was attained in 89.3% of abscesses (definitive treatment 72.3% and partial success 17.0%). There was a statistically significant difference between the iatrogenic and non-iatrogenic groups regarding clinical success (p = 0.031). No mortality was encountered. The complication rate was 6.6% and were all minor. The average rate of recurrence was 10.6%. The mean time to catheter removal was 15.8 ± 13.2 days.

Conclusions
PCD is a safe and effective procedure in the treatment of retroperitoneal abscesses. Procedure-related mortality, morbidity, and complication rates are low. Underlying etiology is a significant factor affecting the outcome. Nevertheless, PCD may provide definitive treatment in the majority of patients.
