Urogenital Tract: the ISUD Classification System

Classification of Urological Diseases

ISUD developed a Classification System of Urological Diseases reflecting today's everyday Urology practice. The classification rationale is simple: firstly, according to the organ affected; secondly, according to the symptom or disease;  thirdly, according to the intervention (diagnostic or therapeutic).  Lastly, the intervention is individualized among differente diagnostic and therapeutic options. The ISUD Classification System is useful for codifying the website material  and using terms as "key-words" when searching.

The numbers added to codification correspond to the most common diseases of the specific organ. Numerical order starts from Congenital and Anatomical Diseases, then follow Functional Diseases and in the end come Tumors. In large chapters of Urology Oncology, there is further subclassification.

For example, prostate cancer is subclassified in localized, metastatic, hormone-refractory. Also, Prostate Cancer falls in a special category related to Bone Disease induced either by cancer itself or its therapy (bone metastases and osteoporosis, respectively).
