用膀胱尿逆流显像诊断前列腺增生所致膀胱输尿管返流

Radionuclide imaging in the diagnosis of vesicoureteral reflux consequent upon benign prostate hyperplasia

目的 探讨膀胱尿逆流显像对前列腺增生 (BPH)所致膀胱输尿管返流 (VUR)的诊断价值。方法 随机对 30例BPH患者行间接法膀胱尿逆流显像 ,检测VUR ,同时行排尿性膀胱尿道造影(MCU)。结果 30例患者中膀胱尿逆流显像检出VUR 7例 ,占 2 3.3% ,其中 3例肾功能有不同程度受损 ;MCU检出VUR 2例 ,占 6 .7% ,2项检查均阳性 2例 ,均阴性 2 3例 ,符合率为 83.3%。结论 膀胱尿逆流显像有利于BPH患者VUR的诊断。

Objective To determine the clinical value of vesicoureteral reflux (VUR) imaging in detecting VUR consequent upon benign prostate hyperplasia(BPH). Methods Indirect VUR imaging and X ray micturition cystourethrography (MCU) were performed on 30 patients. Results By the VUR imaging, 7 in 30 cases were diagnosed with VUR. The positive rate was 23.3%, and 3 cases were detected with renal insufficiency; but by MCU, the positive rate was 6.7%. Two positive cases and 23 negative cases got the same results by both methods, the total concordance was 83.3%. Conclusion VUR imaging is a sensitive, with much lower radiation exposure technique for detecting VUR and for evaluating renal function and it is suitable for BPH patients.
