Also, a small hematoma which appears hyperechoic on US and a high-attenuation collection on CT may be seen at the uterine incision site or the prevesical
space (4, 8).
(9) A large anterior rectal wall haematoma with near total occlusion of the rectal lumen following a TRUS-guided prostate biopsy has also been reported and sizeable prevesical
space of Retzius haematomas have likewise been described.
Those in the superior portion of the supravesical fossa usually result in external hernias, while those arising in the inferomedial part may become lodged in the prevesical
space of Retzius to form an internal hernia.
Table 1: Computed tomography grading of rectus sheath haematoma (5) Type Description I The haematoma is intramuscular, unilateral and does not dissect along the fascial planes II The haematoma can be unilateral or bilateral, with blood between the muscle and the transversalis fascia III Blood is seen to track along the fascial lines, into the peritoneum and the prevesical
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.

. Se realizan cuatro incisiones pequenas en la ingle, dos a cada lado, las superiores se hacen por debajo del tendon del abductor largo a nivel del capuchon del clitoris y las inferiores se realizan 3 cm por debajo y 2 cm lateral a las incisiones superiores.
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.
Then identify the following pelvic structures: uterine fundus, round ligaments, infundibulopelvic (IP) ligaments, posterior cul-de-sac, anterior cul-de-sac, prevesical
peritoneum, and pelvic brim.
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.
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.
The peritoneum covers the bladder dome with creation of an anterior fold with the pelvic wall called prevesical
recess, and a posterior fold with the uterus known as the vesicouterine pouch or anterior cul-de-sac.
After excising the fistulous tract, the first layer sutured is the bladder mucosa, followed by the detrusor and/or prevesical
or endopelvic fascia, and the third or fourth layer incorporates vaginal epithelium.
