The use of ileocecal pouch with appendix as an urethral substitute in patients who are willing to have a orthotopic bladder replacement - point of technique.

INTRODUCTION

The authors describe the technique of orthotopic bladder replacement with an ileocecal pouch and unaltered appendix used as an orthotopic urethral substitute. Additional procedures with regard to the bothersome voiding symptoms will be described.

MATERIAL AND

METHODS

In a small cohort of 5 patients with muscle invasive bladder cancer with tumor involvement of the bladder neck or proximal urethra (2 males/3 females) we performed the following reconstruction. A low pressure reservoir was achieved by antimesenteric longitudinal transection of terminal ileum and cecum/colon ascendens and formation of a pouch. To develop the neourethra, the appendix together with it is accompanying mesentery was drawn through the pelvic floor and sutured to the bulbar urethra in males or formed as a complete neourethra in female patients respectively.

RESULTS

There were no intraoperative nor early postoperative unwanted sequelae. Both male patients experienced recurrent anastomotic urethral stricture, consequently a Memokath stent and artificial urinary sphincter was implanted resulting in normal voluntary micturition. All female patients remained socially continent during the follow up period, one of them performing (clean intermittent catheterization) CIC.

CONCLUSION

The technique described offers the possibility of orthotopic bladder replacement even in traditionally unsuitable, but highly motivated patients, who are requesting orthotopic bladder replacement for improved body image. It allows extension of urethral resection and provides additional continence support. However, additional measures such as urethral stenting, CIC or artificial urinary sphincter implantation may be necessary for long lasting success. Although, not being a routine method for urinary diversion this technique may be used in select patients.
