title: [Pathogenesis of urological complications after radiation therapy].
abstract: Radiation therapy is a treatment modality that is often used in the uro-oncological setting. The common indication for the radiation therapy in the urological sphere is prostate cancer, whether it is used primarily as a radical approach, or postoperatively as adjuvant or salvage therapy. All urological organs are sensitive to radiation injury with the urinary bladder being the most susceptible with a typical cascade including acute and late changes, arising in the dose-dependent manner. The common indication for radiation therapy in urology is prostate cancer, which collaterally affects the urinary bladder and rarely urethra (especially the bulbo-membranous urethra). Ureteral damage and stricture formation is almost always restricted to the cases of intraoperative therapy and external beam radiation therapy for other urological malignancies (gynecological organs, rectum, retroperitoneal soft tissue tumors) and should not be underestimated. Postradiotherapeutic tissue changes, especially of the prostate, can cause difficulties for pathologists and urologists with regard to diagnosis of prostate cancer recurrence and salvage therapy.
