Space
Retropubic space
The extraperitoneal plane behind the pubic symphysis
High-yield
Retropubic and peritoneal spaces are different compartments; bladder injury can produce a collection in one or both depending on the tear.
Overview
The space of Retzius lies between the pubic region and anterior bladder. Loose connective tissue and fat accommodate changes in bladder volume and connect with surrounding extraperitoneal planes. Vascular and supporting structures lie along its inferior and lateral margins.
Reference facts
- Boundaries
- Pubic symphysis and anterior pelvic wall in front; bladder and male prostatic region behind; outlet supports and pelvic-floor fascia below.
- Contents
- Loose fat and connective tissue with related venous channels and pubovesical/puboprostatic supports; its cavity is not lined by peritoneum.
- Communications
- Extends toward anterior abdominal-wall extraperitoneal tissue superiorly and paravesical planes laterally.
Clinical correlation
Pelvic fracture and extraperitoneal bladder injury can cause blood or urine to accumulate here. Collections may extend into adjacent prevesical or abdominal-wall extraperitoneal tissues.
