[Nephrostomy with coaxial balloon occlusion of the ureters for the treatment of a patient with multiple post-radiation vesicovaginal and vesicorectal fistulas].

Post-radiation fistulas are one of the most severe complications of radiotherapy performed for pelvic malignant tumours. A method of coaxial nephrostomy with a putting an occlusive balloon has been proposed for palliative treatment, preparation to surgical treatment or improving the quality of life of patients with contraindications for surgical procedures. A clinical case of a patient with multiple post-radiation vesicovaginal and vesicorectal fistulas who was successfully treated using the proposed method, is presented in the article.
