摘要目的:探讨经皮肾镜联合超声负压吸引术治疗肾周脓肿的临床疗效和安全性。方法:回顾性分析2013年1月至2021年2月浙江省人民医院收治的11例肾周脓肿患者的病例资料。男4例，女7例；平均年龄59(51~76)岁。脓肿位于左侧4例，右侧7例。脓肿最大径平均11.2(8.1~19.2)cm。患者均有发热、腰痛、腹部肿块表现，伴有膀胱刺激征6例，肉眼血尿5例，腹胀、恶心、纳差3例。合并2型糖尿病7例，类风湿性关节炎2例，同侧肾输尿管结石6例。11例中6例有尿路感染病史，1例有上呼吸道感染史，1例为外伤后肾破裂肾周血肿继发感染，3例为经皮肾镜术后肾周血肿继发感染。11例均由单一术者行局麻下经皮肾镜联合超声负压吸引术。分析手术时间、术中出血量、术中抽出脓液量、术后引流管留置时间、术后体温恢复至正常时间、术后住院时间、治疗效果及并发症情况。结果:本组11例手术均顺利完成，其中行单通道8例，双通道2例，三通道1例。手术时间平均44(20~74)min，术中出血量平均15(10~20)ml，术中抽出脓液量平均325(200~500)ml，术后引流管留置时间平均8(6~12)d，术后体温恢复至正常时间平均0.9(0.5~2.0)d，术后住院时间平均9.6(7.0~14.0)d。出院前复查CT均显示肾周脓肿基本消失。术中、术后均无严重并发症。术后随访时间平均4.4(3~8)个月，均无脓肿复发。结论:经皮肾镜联合超声负压吸引术治疗肾周脓肿，创伤小、恢复快、引流彻底、效果确切、并发症少，手术安全、有效。

abstractsObjective:To evaluate the clinical efficacy and safety of ultrasound negative pressure suction with percutaneous nephroscope in the treatment of perirenal abscess.Methods:The clinical data of 11 patients with perirenal abscess admitted to Zhejiang Provincial People's Hospital from January 2013 to February 2021 were retrospectively analyzed. There were 4 males and 7 females. The average age was 59(51-76) years. The abscess was located on the left side in 4 cases and on the right side in 7 cases. The average diameter of abscess was 11.2(8.1-19.2) cm. All patients had fever, low back pain and abdominal mass, accompanied by bladder irritation in 6 cases, gross hematuria in 5 cases, abdominal distension, nausea and anorexia in 3 cases. There were 7 cases with type 2 diabetes, 2 cases with rheumatoid arthritis and 6 cases with ipsilateral kidney and ureter stone. Among the 11 patients, 6 had a history of urinary tract infection, 1 had a history of upper respiratory tract infection, 1 had secondary infection of perirenal hematoma after traumatic renal rupture, and 3 had secondary infection of perirenal hematoma after percutaneous nephroscopy. All patients were treated with ultrasound negative pressure suction with percutaneous nephroscope under local anesthesia by single operator. The operation time, intraoperative blood loss, drainage volume, drainage tube indwelling time, postoperative body temperature returned to normal time, postoperative hospital stay, therapeutic effect and complications were analyzed.Results:All operation procedures of 11 patients were successfully completed, including 8 cases of single channel, 2 cases of double channels and 1 case of three channels. The average operation time was 44(20-74)min, the average amount of blood loss was 15(10-20)ml, the average amount of pus was 325(200-500)ml, the average indwelling time of drainage tube was 8(6-12)d, the average time of body temperature returned to normal was 0.9(0.5-2.0)d, and the average hospitalization time was 9.6(7.0-14.0)d. Before discharge, CT reexamination showed that the perirenal abscess disappeared. There were no serious complications during and after operation. The average follow-up time was 4.4(3-8) months. There was no recurrence in all patients.Conclusions:Ultrasound negative pressure suction with percutaneous nephroscope is one of the safe and effective surgical methods for the treatment of perirenal abscess. It has the advantages of small trauma, quick recovery, complete drainage, exact effect and fewer complications.
