输尿管软镜在CT尿路成像阴性上尿路血尿中的应用（附10例报告）*

Application of flexible ureteroscopy in upper urinary tract hematuria of computed tomography urography negative (10 cases)*

摘要:

目的??探讨及评价上尿路血尿患者CT尿路成像（CTU）检查阴性行输尿管软镜检查的临床意义，提高上尿路血尿患者的病因诊断率。方法?回顾分析该院收治的10例CTU检查阴性的上尿路血尿患者。其中，男7例，女3例，左侧上尿路血尿4例，右侧上尿路血尿6例。均行输尿管软镜检查进一步明确诊断并采取相关治疗措施。结果?输尿管软镜镜检发现3例肾盂肿瘤，1例为肾动静脉瘘，3例考虑为非特异性炎症，3例未见明显异常。结论?CTU检查阴性上尿路血尿患者行输尿管软镜检查对诊断有重要的临床意义。

Abstract:

Objective?To investigate and evaluate the clinical significance of flexible ureteroscopy in computed tomography urography negative patients with upper urinary tract hematuria. To improve the diagnostic rate of patients with upper urinary tract hematuria.?Methods?We retrospectively reviewed the cases of 10 computed tomography urography negative patients with upper urinary tract hematuria. The age ranges from 38 to 75 years old, and the average of them is 45.2 years old. The patients consist of 7 male patients and 3 female patients. Among them, 4 cases were on the left upper urinary tract cases, 6 cases were right upper urinary tract. All patients received flexible ureteroscopy to confirm the diagnosis and take the relevant treatment.?Results?In the total of 10 patients, 3 patients (30%) were diagnosed with tumors of renal pelvis, a renal arteriovenous fistula was found in 1 case (10%), 3 patients (30%) were considered non-specific inflammation, other 3 patients (30%) had no obvious abnormalities. ?Conclusions?Flexible ureteroscopy has significantly clinical diagnosis in computed tomography urography negative patients with upper urinary tract hematuria.
