title: Transurethral endoscopic treatment of seminal vesicle cysts (report of seven cases).
abstract: OBJECTIVE
  Seminal vesicle cysts are a rare disorder of the male reproductive system. The goal of this report was to summarize the radiological manifestations and transurethral endoscopic treatment of large seminal vesicle cysts.
  
  
  METHODS
  The clinical data of seven cases of giant seminal vesicle cysts, including their symptoms, radiological images, transurethral endoscopic treatment, and postoperative follow-up, were retrospectively reviewed.
  
  
  RESULTS
  Computerized tomography and magnetic resonance imaging (MRI) demonstrated the cysts behind the bladder, above the prostate, and away from the midline. The lesions ranged in size from 8.26 cm × 7.98 cm × 4.85 cm to 9.27 cm × 8.95 cm × 8.15 cm. Two cases were associated with ipsilateral renal and ureteral agenesis and were classified as congenital malformations. The other five cases were simple seminal vesicle cysts thought to be secondary to acquired ejaculatory duct obstruction. All seven cases were successfully treated using transurethral endoscopic unroofing with cautery of the mucosa. All the seminal vesicle cysts were confirmed by pathologic examination. No malignant disease was found. All preoperative symptoms resolved after surgery. No complications were observed. No patient developed abnormalities of erection, ejaculation, or orgasm. No bladder or rectal injuries were noted. The seminal vesicle cysts were significantly decreased in size or absent 3-6 months after treatment.
  
  
  CONCLUSIONS
  MRI best characterized seminal vesical cysts and their cause. Transurethral unroofing with cautery of the mucosa is an extension of well-accepted cystoscopic techniques. It is safe, easy to perform, and effective. It is the preferred method for the treatment of large seminal vesicle cysts.
