摘　　要：目的评价腔内导管超声诊断上尿路疾病的可行性和有效性。方法上尿路疾病患者68例。男30例，女38例。年龄17～81岁，平均58岁。采用频率10MHz、外径8F微探头腔内导管超声探测显示肾盂及周围病变48例，输尿管及周围病变20例；其中双侧检测2例，随访检测3例，共73例次。根据患者病变病理或临床随访结果评价腔内导管超声诊断的有效性。结果68例患者中，成功检测62例（91％），其中肾盂及周围病变46例（96％）、输尿管及周围病变16例（80％）。导管超声检出肾盂及周围病变异常41例（89％），其中经手术病理诊断28例、经临床随访和根据其他检查确诊7例、未被证实6例；检出输尿管及周围病变异常者12例（75％）。20例输尿管及周围病变者中经手术病理诊断或临床随访和根据其他检查确诊18例，14例行输尿管手术，输尿管微结石4例采用保守治疗。结论上尿路腔内微探头导管超声探测能清晰显示腔内病灶的形态、大小、回声和部位，而且能精细、准确、实时地显示腔外结构，为上尿路疾病诊断提供了一种新方法。Objective To evaluate the feasibility and efficiency of endoluminal catheter-based ultrasonography on diagnosis of upper urinary tract diseases. Methods From January 1997 to December 2006, the clinical data of upper urinary tract of 68 cases who examined by endoluminal ultrasonography with a 10 MHz miniature ultrasound transducer and a 8 F outer catheter were reviewed. There were 30 males and 38 females aged 17-81 years with an average of 58 years. The renal pelvis and its surrounding structures were examined in 48 cases and the ureter and its surrounding structures were examined in 20 cases. The total of 73 sides had experienced by this technique. The accuracy of diagnosis with endoluminal catheter-based ultrasonography was evaluated by the pathology and clinical fol-low-up. Results The total success rate of the ultrasound probe introduced into ureter was 91G in 68 cases. In the pelvis group it was 96 G （46/48） and the ureter group 80 G （16/20）. In renal pelvis abnomalities, the detectable rate of abnormal by ultrasonography was 89 G （41/46）. The total detecta ble rate in ultrasound probe group was significantly higher than that in other equipment groups （P〈0.01）. The detectable rate of ultrasonography on ureter disease was 75%（l2/16）. Conclusion Endoluminal catheter-based ultrasonography is an effective, safe technique for the diagnosis of diseases in the upper urinary tract.
