What is the best drainage method for a Perinephric abscess?
Percutaneous drainage of a perinephric abscess is an effective minimally invasive treatment modality. Therefore, when a PNA has to be drained, we recommend PCD as the primary drainage method because, as shown in our series, it can save 69% of patients an open surgery.
How do you drain Perinephric abscess?
Perinephric abscesses larger than 3 cm should be drained while abscesses smaller than 3 cm should be initially treated with an antibiotic. Percutaneous catheter drainage should be done if symptoms and radiographic abnormality persist after several days of appropriate antibiotics treatment.
Can kidney abscess be treated without draining?

What is Perinephric fluid collection?
Perinephric fluid is a critical finding of ultrasonography in daily clinical practice. The condition includes a broad spectrum of diseases and the fluid may arise from the kidney or adjacent retroperitoneal structures. We present a case series of patients with perinephric fluid collection with ultrasound images.
What is Perinephric abscess?
A perinephric abscess is a collection of suppurative material in the renal parenchyma or perinephric space, with a presentation that is insidious (> 14 d). This abscess formation occurs secondary to urinary tract obstruction and/or hematogenous spread from infection sites.
What is a Perinephric abscess?
What causes fluid around kidneys?
Hydronephrosis is swelling of one or both kidneys. Kidney swelling happens when urine can’t drain from a kidney and builds up in the kidney as a result. This can occur from a blockage in the tubes that drain urine from the kidneys (ureters) or from an anatomical defect that doesn’t allow urine to drain properly.
What is the best treatment for A perinephric abscess?
When kidneys are not functioning or are severely infected, nephrectomy (open or laparoscopic) is the classic treatment for perinephric abscesses. Percutaneous drainage is relatively contraindicated in large abscess cavities that are filled with a thick purulent fluid.
What is the pathophysiology of perinephric abscess?
Perinephric abscesses may arise from non-renal contiguous infections. These infections may originate from trauma, an extension of infection in other body organs including liver, cervix, pancreas, gallbladder, and appendix or from small bowel Crohn’s disease, or vertebral osteomyelitis.
Does a negative U/a rule out A perinephric abscess?
