Abstract：Objective:To compare the efficacy of percutaneous ultrasonography-guided endoscopic lavage and open drainage for perinephric abscess.Methods:The files of 90 patients who underwent drainage for perinephric abscesses from January 2011 to January 2016 in Department of Urology in People's Hospitalof Xinjiang Uygur Autonomous Region were evaluated.The method of drainage for each patient was performed according to the clinical decision of the treating physician.Percutaneous ultrasonography-guided endoscopic lavage was used for drainage of the abscess in 45 patients (endoscopic group),and remaining 45 patients were managed with open drainage (open drainage group).Cure was defined as complete obliteration of the abscess cavity.The cure rates,complications,and postoperative hospital stay were compared between two groups.Results:The study included 52 males and 38 females with mean age of (45.3± 16.1) years old.The most common predisposing factors were stones and diabetes mellitus.There was no statistically significant difference in cure rate between two groups (95 ％ vs.97 ％,P＞0.05).Percutaneous ultrasonography-guided endoscopic lavage of perinephric abscesses resulted in shorter postoperative hospital stay than open drainage (4.0 vs.11.8 d,P＜0.05).Complications were observed in 6.6％ of endoscopic group and 11.1 ％ of open drainage group (P＞0.05).Conclusions:Percutaneous ultrasonography-guided endoscopic lavage is an effective and safe minimally invasive treatment for patients with perinephric abscesses.
