Nefrostomía percutánea bilateral como tratamiento de la cistitis hemorrágica severa

objective: to report a case of severe hemorrhagic cystitis successfully treated by bilateral percutaneous nephrostomy. methods: the case of a 67-year-old female patient who had monosymptomatic gross hematuria with clots is reported. results: standard conservative treatments failed and the patient developed a clot-retention plugged bladder. endoscopic evacuation and electrocoagulation of bleeding areas was unsuccessful. due to persistent hematuria and development of renal failure and hemodynamic instability, bilateral percutaneous nephrostomy was performed. at 24 hours, hematuria ceased, patient recovered hemodynamic stability, and no additional blood transfusions were required. conclusions: bilateral percutaneous nephrostomy may be a valuable option for the treatment of hemorrhagic cystitis when standard conservative measures have failed and as a prior step to performance of other more invasive procedures.
