| 目的 探讨X线数字断层融合技术（DTS）诊断输尿管结石的价值。方法 收集经临床手术证实为输尿管结石的患者224例，均于发病当天接受过超声、泌尿系平片（KUB）及DTS检查。结石总数240枚，上段55枚，中下段185枚。以临床手术结果为金标准，比较3种检查方法的检出率。结果 DTS、KUB、超声对所有结石、上段结石、中下段结石的检出率分别为：87.50%（210/240）、45.83%（110/240）、56.25%（135/240），90.91%（50/55）、70.91%（39/55）、100%（55/55）和86.49%（160/185）、38.38%（71/185）、43.24%（80/185）。两两比较除上段结石中DTS与超声（P=0.022）、中下段结石中KUB与超声（P=0.341）、所有结石中KUB与超声（P=0.022）检出率差异无统计学意义之外，其余两两比较差异均有统计学意义（P均<0.0167）。结论 DTS对输尿管结石具有较高的检出率，特别在较难诊断的输尿管中下段结石上表现出明显优势，其检出率明显高于KUB及超声，具有较高的临床应用价值。 |

| Objective To explore the value of X-ray digital tomosynthesis (DTS) in diagnosis of ureteral calculi. Methods Totally 224 patients with ureteral calculi confirmed by clinical surgery underwent the ultrasound, plain film of kidney-ureter-bladder (KUB) and DTS check on the same day. The total number of calculi was 240, and out of which 55 were in the upper segment, and 185 in middle-lower segment. Taking the clinical results as the golden standard, the detection rates of the three methods were obtained and compared. Results The detection rates of DTS, KUB and ultrasound in all ureteral calculi, upper calculi, and middle-lower calculi were 87.50% (210/240), 45.83% (110/240), 56.25% (135/240);90.91% (50/55), 70.91% (39/55), 100% (55/55); 86.49% (160/185), 38.38% (71/185), 43.24% (80/185). There were no significant differences of the detection rates in DTS and ultrasound in upper ureteral calculi (P=0.022), KUB and ultrasound in middle-lower ureteral (P=0.341), KUB and ultrasound in all calculi (P=0.022). And significant differences were found in other pairwise comparisons (all P<0.0167). Conclusion DTS has a high value in detection of ureteral calculi, especially of calculi in the middle-lower ureter, and the detection rate is higher than those of ultrasound and KUB. |
