Abstract
To compare the results of percutaneous and open drainage for perinephric abscess. The files of 86 patients who underwent drainage for perinephric abscesses from April 2001 through March 2008 were evaluated. The method of drainage for each patient was performed according to the clinical decision of the treating physician. Percutaneous tube drain (PCD) was used for drainage of the abscess in 43 patients (group 1), while the other 43 patients were managed with open drainage (group 2). Cure was defined as complete obliteration of the abscess cavity. The cure rates, complications, and hospital stay were compared between both groups. The study included 50 males and 36 females with mean age 44.2 + or - 17.3. The most common predisposing factors were diabetes mellitus and/or stones. Open drainage of perinephric abscesses resulted in a statistically significant higher cure rate (98% versus 69%, p < 0.001) and shorter hospital stay than PCD (3.6 versus 6 days, p < 0.001). Failure of complete drainage of multilocular abscess was observed in 8 of 13 cases (61.5%) in group 1 and one of 38 cases (2.6%) in group 2 (P < 0.001). Complications were observed in 7% of group 1 and 11.5% in group 2 (P = 0.45). After mean follow-up of 19 months, 9 of 46 patients (19.6%) had recurrence; 7 of them were in group 1. Percutaneous drainage of perinephric abscess is an effective minimally invasive treatment. However, PCD is not the optimal method for drainage of multilocular abscess because open surgical drainage provided higher cure rates and shorter hospitalization than PCD.
Highlights
Perinephric abscess (PNA) is defined as an abscess outside the renal capsule but within Gerota’s fascia
After the advent of various imaging modalities such as ultrasonography and computed tomography, percutaneous drainage (PCD) with radiological guidance has become widely used for most abdominal abscesses including selected cases of PNA (3)
The computerized files, radiographic images, operative and postoperative data of 86 patients who were treated for perinephric abscess at our center from April 2001 through March 2008 were retrospectively assessed
Summary
Perinephric abscess (PNA) is defined as an abscess outside the renal capsule but within Gerota’s fascia. They are rare in comparison to other infections involving the genitourinary tract but they can cause significant morbidity and mortality (1). The first report of open surgical drainage of PNA was described by the French physician Germain. There have been many reported studies that have evaluated PCD as a minimally invasive treatment for PNA (3-6). To our knowledge no previous series has compared PCD versus open drainage in the management of PNA.
