We developed a new technique to determine the laterality of microscopic hematuria by means of gas cystoscopy.
An originally designed catheter system consisted of two catheters. On the tip of an inner catheter, a urine dipstick for blood was attached, with a cap on the tip of an outer catheter to keep the dipstick dry. In order to react a dipstick with the urine coming out from a ureteral orifice in the bladder, CO2 was insufflated into the bladder through a cystoscope (gas cystoscopy). The laterality of microscopic hematuria was determined in the bladder, based on the color reaction on the dipstick.
This technique was performed successfully in 14 (88%) of 16 cases with microscopic hematuria. The laterality of microscopic hematuria was determined to be ipsilateral in 6 patients, which coincided with the side of a urological upper urinary tract disorder. In contract, bilateral microscopic hematuria was confirmed in 8 patients with glomerular disorders.
The diagnostic process in patients with microscopic hematuria remains unsolved for urologists and nephrologists. This technique may provide a new approach in diagnosing microscopic hematuria.
我们开发了一种通过气体膀胱镜检查来确定显微镜下血尿侧别的新技术。
最初设计的导管系统由两根导管组成。在内导管的尖端附着一个用于检测血液的尿试纸条，在外导管的尖端有一个帽，以保持试纸条干燥。为了使试纸条与从膀胱输尿管口流出的尿液发生反应，通过膀胱镜向膀胱内注入二氧化碳（气体膀胱镜检查）。根据试纸条上的颜色反应，在膀胱内确定显微镜下血尿的侧别。
在16例显微镜下血尿患者中，有14例（88%）成功实施了该技术。6例患者显微镜下血尿的侧别被确定为同侧，这与泌尿系统上尿路疾病的一侧相符。相比之下，8例肾小球疾病患者被证实为双侧显微镜下血尿。
对于泌尿外科医生和肾内科医生来说，显微镜下血尿患者的诊断过程仍然没有解决。这项技术可能为诊断显微镜下血尿提供一种新方法。
