Efficacy of ultrasound-guided percutaneous drainage in the treatment of psoas abscess

Aim: In this study, we aimed to evaluate the efficacy of ultrasound-guided percutaneous drainage applied to cases determined with psoas abscess, and to investigate predisposing factors and micro-organisms causing the disease.Material and Methods: Twenty-eight patients were examined, including 15 males and 13 females, aged 22-87 years, who underwent ultrasound-guided percutaneous drainage. Predisposing factors for the development of psoas abscess, the need for an additional surgical procedure after percutaneous abscess drainage, length of stay in hospital after the procedure, complications, and agent micro-organisms were evaluated. The efficacy of percutaneous drainage in the treatment was investigated.Results: The most common agents were determined to be Staphylococcus aereus, Escherichia coli, and Mycobacterium tuberculosis. Primary psoas abscess was determined in 6 (21.4%) patients and secondary psoas abscess in 22 patients. In cases with secondary psoas abscess, skeletal origin predisposing factors (spondylodiscitis, history of abdominal or vertebral surgery) were seen to most often play a role in the etiology. In 20 of the 22 (78.5%) patients with secondary psoas abscess, effective treatment was applied with antibiotherapy and percutaneous drainage. The mortality rate was 10.7%.Discussion: Low morbidity and mortality rates are the greatest advantages of percutaneous drainage. Although CT has emerged as a better diagnostic method for psoas abscess, ultrasound-guided percutaneous drainage has the advantages of easy availability, low cost, and it does not contain radiation. Ultrasound -guided percutaneous drainage is an effective and reliable method in the treatment of psoas abscess.
