title: Robotic-assisted laparoscopic vesiculectomy for lower urinary tract obstruction by a large seminal vesicle cyst.
abstract: BACKGROUND
  Seminal vesicle (SV) cysts are rare, benign lesions. Most of them are congenital in origin and are usually diagnosed incidentally due to extensive imaging. When symptomatic, surgical excision is recommended.
  
  
  METHODS
  We describe the case of a 17.2cm seminal vesicle cyst removed using a transperitoneal, robotic-assisted laparoscopic approach in a 45-year old male with lower urinary tract symptoms and no other genitourinary abnormality.
  
  
  CONCLUSIONS
  Laparoscopic excision of seminal vesicle cysts is a minimal invasive alternative to the open technique with single-center studies reporting high success rates. With the advent of the robotic platform, urologists have shifted to this approach especially for confined anatomical spaces such as the pelvis. To our knowledge this is the largest seminal vesicle cyst described in the literature that has been managed by minimally invasive surgery.
  
  
  CONCLUSIONS
  With the advantage of combined 3D vision and wristed instrumentation, excision of large seminal vesicle cysts by robotic assisted laparoscopic approach is feasible, safe and regarded as a natural continuity of conventional laparoscopy. Previous experience in Robotic assisted laparoscopic prostatectomy (RALP) especially in the posterior dissection technique is recommended.
