Ex vivo ultrathin endoscopy of the seminal vesicles

Abstract

Purpose: We used a newly developed ultrathin endoscope to examine the interior of the seminal vesicles ex vivo.

Materials and methods: Resected specimens of bladder (8 patients) and prostate (2) cancer were examined.

Results: Examination was successful in 3 specimens with an antegrade approach. The tortuous lumen of the seminal vesicles made passage of the guide catheter difficult. The mucosa of the seminal vesicles and vas deferens was clearly visible.

Conclusions: Our results suggest that ultrathin endoscopy in useful for diagnosis and evaluation of disorders of the seminal vesicles.
