[A new approach in the diagnosis of obstructive azoospermia].

The author describes a new approach to the diagnosis of obstructive azoospermia. The method consists of administration of Panetblau in the seminal duct by an operative way and blue staining is anticipated in urine. This method gives a possibility to examine the patency of seminal pathways at proximal direction. This method was used in 78 patients with mean age of 29 years, suffering from chronic nonspecific epididymitis and obstructive azoospermia and fertile problems. Allergic reaction, caused by Patenblau occurred only in one patient. The proposed method has the following advantages: it is an objective method for establishment of the patency of the seminal pathways, the drug used is water solution, which does not irritate and does not obstruct the lumen of seminal duct, and this method avoids roentgenological irradiation of patients with disturbed spermatogenesis and has a definite economic effect as well.
