Retropubic space

Retropubic space is a potential avascular space located between the pubic symphysis and the urinary bladder. The retropubic space is a preperitoneal space, located behind the transversalis fascia and in front of peritoneum.

Other names for the retropubic space are "Cave of Retzius" or "Retzius' space", named after the Swedish anatomist Anders Retzius (1796-1860).

The space is a useful landmark in different gynecological and urological surgeries.
