目的:比较B超和X线对肾积水的诊断标准,为临床提供有价值的诊断依据。方法:对经手术和临床确诊的207例尿路梗阻性肾积水病例的B超与X线平片和静脉肾盂造影的特点进行回顾性分析。结果:B超显示肾积水174例,阳性率84.05%;X线显示肾积水91例,阳性率47.39%。结论:B超对少量、轻度肾积水诊断的特异性明显优于X线;对肾绞痛、尿频尿急或伴血尿等临床表现者,如B超检查发现肾窦分离>0.7cm者应随访。
Objective: To compare diagnostic criteria of B-ultrasound and X-ray to hydronephrosis and provide valuable diagnostic evidence for clinical practice. Methods: The characteristics of B - ultrasonography, X - ray plain film and intravenous pyelography in 207 patients with urinary tract obstructive hydronephrosis diagnosed surgically and clinically were analyzed retrospectively. Results: B ultrasound showed hydronephrosis 174 cases, the positive rate of 84.05%; X-ray showed hydronephrosis in 91 cases, the positive rate of 47.39%. Conclusion: The specificity of B-ultrasound in diagnosis of small amount and mild hydronephrosis is obviously better than that of X-ray. For those with clinical manifestations such as renal colic, urinary urgency or hematuria, B-mode ultrasonography found> 0.7cm Should be followed up.
