报告肾周围感染４１例，除２０例经应用大剂量抗生素治愈外，余２１例主要经手术引流治愈，其中９例切开引流，６例经皮穿刺抽吸或置管引流，６例经皮肾镜置管引流冲洗。对肾周围感染的病因、诊断、治疗，尤其是手术引流方式等进行了讨论，认为肾外因素致肾周围感染不容忽视，强调Ｂ超尤其是ＣＴ可明确诊断并指导治疗。 Reported 41 cases of perinatal infection, except for 20 cases cured by high-dose antibiotics, the remaining 21 cases were mainly cured by surgical drainage, including 9 cases of drainage and drainage, 6 cases of percutaneous aspiration or catheter drainage, 6 cases of percutaneous Renal tube drainage tube flushing. The etiology, diagnosis and treatment of perinatal infection, especially the way of surgical drainage are discussed. It is concluded that renal peripheral infection caused by extra-renal factors should not be neglected. It is emphasized that B-ultrasonography, especially CT, can definitely diagnose and guide the treatment.
