[Right Essential Renal Hematuria that Can Not Be Coagulated with a Ureteroscope Treated by Hydrogen Peroxide Instillation : A Case Report].

ABSTRACT

We report a case of right essential renal hematuria treated by hydrogen peroxide instillation. A twentythree-year-old man visited our hospital with gross hematuria, urinary retention and right pelvic pain. Our diagnosis was right renal essential hematuria. A bleeding point was found in the right renal calix using a flexible ureteroscope. Bleeding was prolonged in spite of ureteroscopy and diathermy fulguration. We performed treatment with hydrogen peroxide instillation. The patient made a satisfactory recovery postoperatively, and no complications have been observed. Retrograde hydrogen peroxide instillation therapy is a useful treatment for essential renal hematuria that can not be coagulated with a ureteroscope.
