title: Intraoperative catheter management during laparoscopic excision of a giant bladder diverticulum.
abstract: BACKGROUND
  Massive bladder diverticula present a technical challenge to the laparoscopic surgeon. We describe a laparoscopic approach to transperitoneal diverticulectomy, using a specific catheter arrangement to allow excellent control of the various portions of the procedure.
  
  
  METHODS
  A 49-year-old male with longstanding frequency was diagnosed with a 1000 cc bladder diverticulum and bladder neck outlet obstruction. Laparoscopic transperitoneal diverticulectomy was performed using a triple catheter arrangement: endoscopic placement of a Councill catheter in the diverticulum, fluoroscopic positioning of an occlusion balloon catheter in the renal pelvis, and placement of a Cope loop suprapubic tube. Additionally, a transurethral incision of the prostate was performed.
  
  
  RESULTS
  The procedure was completed laparoscopically using a four port transperitoneal approach. During the procedure, the diverticulum could be filled and emptied as needed; the catheter across the diverticular neck facilitated subsequent closure of the bladder wall defect. The diverticulum was completely excised. The remaining defect in the bladder was then closed in 2 layers. The patient was discharged on postoperative day 3.
  
  
  CONCLUSIONS
  Careful planning and arrangement of catheters in the bladder, ureter, and diverticulum facilitates laparoscopic transperitoneal diverticulectomy of even a very large volume diverticulum.
