Additionally, a peer reviewed study titled Reservoir Alternate Surgical Implantation Technique: Preliminary Outcomes of Initial PROPPER Study of Low Profile or Spherical Reservoir Implantation in Submuscular Location or Traditional Prevesical
Space authored by Edward Karpman, et al, was published in the Journal of Urology in January 2015.
The control pump is implanted within the scrotum, and the balloon reservoir is placed either intra-abdominally or in an extraperitoneal prevesical
space of Retzius.
These segments are associated with the Waldeyer's Sheath and the prevesical sphincter described by S.
Protection against vesicoureteral reflux is provided by the submucosal ureteral tunnel next to the Waldeyer's muscular sheath and by the circular muscular fibres of the prevesical sphincter at the distal ureter.
This is connected to a balloon that is implanted into the prevesical space, which in turn is connected to a small, finger-operated pump that is implanted into one side of the labia.
Implantation is done using a suprapubic incision to open the prevesical space.
AMS says the Acticon Neosphincter is a silicone-based prosthesis consisting of an occlusive cuff implanted around the anal canal, a pressure-regulated balloon implanted in the prevesical
space, and a control pump.
