输尿管镜检术在早期泌尿系结核中的诊断价值

Diagnostic value of ureteroscopy and mucosa biopsy in early urinary system tuberculosis

目的:探讨输尿管镜镜检并活检术诊断早期泌尿系结核的价值。方法:回顾分析45例泌尿系结核患者的临床资料及应用输尿管镜取黏膜活检的诊断结果,并对比分析其与同期进行的尿沉渣抗酸杆菌检测(AFB)和泌尿系统影像学检查。结果:所有患者均成功行输尿管活检术,45例中有40例活检病理诊断证实为泌尿系结核,诊断阳性率为88.89%,高于同期的尿沉渣抗酸杆菌检查诊断的30例(阳性率为66.67%)和泌尿系影像学检查诊断的22例(阳性率为48.89%);活检术分别与两者差异均有统计学意义(P<0.05)。所有病例术后均无严重并发症发生。结论:输尿管镜镜检并活检术是有效、安全的诊断泌尿系结核的方法。

Objective To evaluate the diagnostic value of ureteroscopy and mucosa biopsy in early urinary system tuberculosis. Methods The clinical data and mucosa biopsy results of 45 patients underwent ureteroscopy were retrospectively analyzed, and were compared with the results of urinary urine acid fast bacilli （AFB） detection and urinary radiology administered simultaneously. Results All patients received mucosa biopsy of the ureter with ureteroscopy, the positive rate of urinary system tuberculosis diagnosed by ureteroscopy and mucosa biopsy was 88.89%, which was higher than those of AFB detection （66.67%, 30/45） and urinary radiology （48.89%, 22/45） （P 〈 0.05 ）. There was no severe complications occurred. Conclusion It was regarded that ureteroscopy and mucosa biopsy is one of the effective and safe methods for the diagnosis of urinary system tuberculosis.
