Abstract:
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 uhrasonography 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 follow-up. Results The total success rate of the ultrasound probe introduced into ureter was 91%in 68 cases.In the pelvis group it was 96%(46/48)and the ureter group 80%(16/20).In renal pelvis abnomalities,the detectable rate of abnormal by ultrasonography was 89%(41/46).The total detectable 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%(12/16). Conclusion Endoluminal catheter-based ultrasonography is an effective,safe technique for the diagnosis of diseases in the upper urinary tract.
