How do you treat Perinephric abscess?
The mainstay of treatment for perinephric abscess is drainage. Antibiotics are mainly used as an adjunct to percutaneous drainage because they help to control sepsis and to prevent the spread of infection.
What does Perinephric mean?
or occurring around the kidney
(pĕr″ĭ-nĕf′rĭk) [Gr. peri, around, + nephros, kidney] Located or occurring around the kidney.
What is the management of pyelonephritis?
Outpatient oral antibiotic therapy with a fluoroquinolone is successful in most patients with mild uncomplicated pyelonephritis. Other effective alternatives include extended-spectrum penicillins, amoxicillin-clavulanate potassium, cephalosporins, and trimethoprim-sulfamethoxazole.
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 causes Perinephric fluid?
Ultrasonography (US), computed tomography (CT), and magnetic resonance imaging (MRI) can not only show and characterize the fluid, but also may help determine the underlying cause of the perinephric fluid collection, such as ureteric obstruction, kidney injury, infection, or renal lymphangiectasia.
How is Perinephric abscess diagnosed?
In order to identify the abscess and define its extent, computed tomography (CT) scans are often used. CT scans can also help determine the presence of any radiological abnormalities that may be indicative of an abscess. In some cases, ultrasonography can also be used to identify the presence of an abscess.
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.
Which antibiotics treat a kidney infection?
Commonly used antibiotics for kidney infections include ciprofloxacin, cefalexin, co-amoxiclav or trimethoprim. Painkillers such as paracetamol can ease pain and reduce a high temperature (fever). Stronger painkillers may be needed if the pain is more severe.
What is a perinephric abscess?
Perinephric abscess refers to the accumulation of infected material and consequent necrosis of tissues within the perinephric space, surrounding the kidneys. It can result from complications of pyelonephritis or it can be due to spread of infection from other body organs through the bloodstream.
What is the initial modality of treatment for perinephric abscess?
Medical Therapy. Therefore, a trial of percutaneous drainage should be the initial modality of treatment for perinephric abscess. This approach is contraindicated in the setting of bleeding diathesis and when a hydatid cyst may be present. Administer broad-spectrum intravenous antibiotics before the procedure.
When should percutaneous drainage be delayed in perinephric abscess?
Empiric therapy can be delayed for percutaneous drainage in a stable patient if drainage can be done immediately to identify the causative organism. Perinephric abscesses larger than 3 cm should be drained while abscesses smaller than 3 cm should be initially treated with an antibiotic.
When is nephrectomy indicated in the treatment of perinephric abscess?
Surgical drainage of the abscess and/or nephrectomy is warranted in a patient that failed medical treatment. Nephrectomy is also warranted in patients with a chronically infected and atrophic kidney that develop a perinephric abscess.
