摘要
The causes oflGH （Isolated gross hematuria）, as the only symptom or associated with ARU （acute retention of urine） caused by clots in the urinary tract in patients who do not have a previous diagnosis of urological malignant pathology and to study the immediate mortality in patients with that sign are described. A descriptive observational study of the etiologies of patients shows the above mentioned symptomatology from the 1 st of January to the 30th of June of 2008 in the Emergency Department which received follow-up treatment up to December 2010. It also describes the mortality before the definitive diagnosis and the days between receiving attention in the Emergencies Department and the diagnostic tests. One hundred and four cases with the criteria described above were evaluated. Of these, 20.0% turned out to have bladder, prostate or kidney cancer; the bladder being the most affected organ. Of all the pathology, benign and malignant, the most frequent one is the benign hypertrophy of the prostate （49.8% of the total）. Of the total, 4.8% of the patients died in the following weeks before finishing the diagnostic study. Isolated gross hematuria is a clinical symptom closely related to urological malignant pathology and it does not have an insignificant mortality rate in a short period of time. For these reasons it is necessary to accelerate the diagnostic tests as soon as the patient presents the symptom.
