[Cystoscopy and its importance in urology].

From the enumeration of modern endoscopic methods for diagnosis and treatment of urological disease, the characteristics of their value and their importance for modern urology becomes evident that by means of these methods, the basis of which was created 100 years ago with the introduction of the cystoscopy, examination and treatment became possible in all regions of the urinary tracts. Based on cystoscopy a subspeciality in urology developed, which might be called endoscopic surgery in urology. The endoscopic treatment methods are relatively atraumatic and loaded with a more insignificant complication rate than the open operative interventions. However, they demand an exact knowledge of the indications and contraindications. By the great possibilities which nowadays open the modern methods of endoscopic diagnostics and therapy we are indebted to their inventors still 100 years after the detection of the cystoscope, among the inventors German researchers and masters play an important role.
