Robotic-assisted laparoscopic vesiculectomy for lower urinary tract obstruction by a large seminal vesicle cyst

Abstract INTRODUCTION 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. PRESENTATION OF CASE We describe the case of a 17.2 cm 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. DISCUSSION 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. CONCLUSION 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.
