Application of the Ureteroscope for Diagnosis and Treatment of the Seminal Vesicle Diseases.

The objective of this paper is to apply the transurethral endoscopic technique with the ureteroscope for diagnosis and treatment of the seminal vesicle and ejaculatory duct disorders. At present there is no special equipment designed to enter directly into the seminal vesicle cavity under direct vision. Sixty patients with disorders of the seminal vesicle were included in this study. A 6.5 F rigid ureteroscope (Richard Wolf GmbH, Knittlingen, Germany) was inserted into the posterior urethra to find the verumontanum. Then a 3F catheter (Shanghai Kangge JJMC, Shanghai, China) was inserted into the verumontanum. After that the 6.5 F ureteroscope was introduced into the ejaculatory duct and seminal vesicle to examine them under direct observation. A total of 55 patients were diagnosed and cured successfully with the ureteroscope; 42 (76.4%) patients were discovered to have hemospermia. They were given an anti-inflammatory and seminal vesicle washing. Eight (14.5%) patients who had small stones in the seminal vesicle were offered the operation of the stones removal. Five (9.1%) patients were found to have seminal vesicle gland cysts. The orifices of ejaculatory duct were not found in 3 patients among 5 who were operated unsuccessfully. The ureteroscope failed to enter the seminal vesicle in 2 patients. Some diseases of the seminal vesicle and ejaculatory duct can be easily diagnosed and treated in the clinical practice using a ureteroscope. Transurethral endoscopy technique with the ureteroscope for diagnosis and therapy of the seminal vesicle and ejaculatory duct disorders is safe and practicable.
