Abstract
PURPOSE We aimed to evaluate technical and clinical success and safety of computed tomography fluoroscopy (CTF)-guided percutaneous pigtail drainage (PPD) placement in patients with infected renal and perirenal fluid collections. METHODS This retrospective analysis comprised 44 patients (52.27% men;age, 57.1 +/- 18.5 years) undergoing low-milliampere (10-20 mA) CTF-guided PPD placement in 61 sessions under local anesthesia from August 2005 to November 2016. Infected fluid collections (n=71) included infected renal cysts (12.68%), renal and perirenal abscesses due to comorbidities (23.94%), or fluid collections after renal surgery or urological intervention (63.38%). Technical success was defined as PPD placement with consecutive fluid aspiration, clinical success as normalization or marked improvement of clinical symptoms (e.g., flank pain, fever) and inflammatory parameters (leukocyte count, C-reactive protein) after minimally invasive combination therapy (intravenous broad-spectrum antibiotics and drainage). Complications were classified according to the CIRSE classification. RESULTS Overall, 73 single lumen PPD (7.5-12 F) were utilized (1 PPD per session, 69.86%;2 PPD per session, 15.07%). In 4 cases, PPD could not be inserted into the fluid collection (4.11%) or could not be aspirated (1.37%), yielding overall 94.5% primary technical success. Mean duration of functioning PPD before removal was 10.9 days. Adverse events within 30 days comprised PPD failure (2.27%) or secondary dislocation (Grade 3, 11.36%) and one death (Grade 6, unrelated to intervention, 2.27%). Additional invasive measures after primary CTF-guided PPD were required in 5 patients (nephrectomy 6.82%, partial nephrectomy 2.27%, surgical drainage 2.27%). Thus, clinical success using only minimally invasive measures was achieved in 39 of 44 patients (88.64%). CONCLUSION Given a minor proportion of patients requiring surgical revision, combined antibiotics and CTF-guided PPD of infected renal and perirenal fluid collections provides an excellent technical and clinical outcome.
