Diagram of rigid wall, fixed-volume reservoir for urinary bladder prosthesis. Transcutaneous stomal cap contains a replaceable air-permeable, water-impermeable membrane. Transcutaneous and anastomotic components of the silicone rubber reservoir are bonded with porous alloplasts to achieve watertight unions. An endoscopically exchangeable “urethral valve” could be placed at bladder outlet.
