SERRANO, Álvaro et al. Unilateral essential hematuria: diagnosis, endoscopic treatment, and new diagnostic-therapeutic algorithm. Arch. Esp. Urol. [online]. 2007, vol.60, n.2, pp.155-164. ISSN 0004-0614.

Objectives: To perform a long-term evaluation of 15 patients with unilateral essential hematuria, with the aim of determining the causes of bleeding and the response to endoscopic treatment. To design a diagnostic-therapeutic algorithm for patients with unilateral essential hematuria. Methods: We retrospectively review the clinical data of 15 patients with unilateral essential hematuria evaluated by rigid ureterorenoscopy (15 cases), flexible ureteropyelocalycoscopy (15 cases) and percutaneous nephroscopy (3 cases). In 4 patients electric fulguration of the pyelocalicial lesions was carried out. Results: 14 of the 15 patients were successfully treated endoscopically. Only one patient presented recurrence of the hematuria. Mean follow-up time was 64 months (4-168 months). No patient suffered any relevant complication secondary to the endoscopic treatment. Conclusions: The cause of bleeding in patients with unilateral essential hematuria is determined only in a few, but endoscopic treatment is successful in a high percentage of cases. We consider that upper urinary tract endoscopy, mainly flexible ureteropyelocalycoscopy, has strongly impacted the diagnosis and treatment of essential unilateral hematuria. We present a new diagnostic-therapeutic algorithm, based on the usefulness of flexible instrumentation.
