Xiphoid process: • Inferior: Pubic bone and iliac crest: Level of L4. • Umbilicus: Level of IV disc L3-L4 Abdominal Quadrants Formed by two intersecting lines: Vertical & Horizontal Intersect at umbilicus. Quadrants: Upper left. Upper right. Lower left. Lower right Abdominal Regions Divided into 9 regions by two pairs of planes: 1- Vertical Planes: -Left and right lateral planes - Midclavicular planes -passes through the midpoint between the ant.sup.iliac spine and symphysis pupis 2- Horizontal Planes: -Subcostal plane - at level of L3 vertebra -Joins the lower end of costal cartilage on each side -Intertubercular plane: -- At the level of L5 vertebra - Through tubercles of iliac crests.

Axial CT Cystogram
81 y/o male with abdominal pain s/p cystoscopy Edward Gillis, DO David Karimeddini, MD Axial CT Cystogram Axial CT Cystogram Axial CT Cystogram Coronal CT Cystogram ? Intra- and extraperitoneal bladder rupture Axial CT Cystogram: At the mid pelvis, contrast is seen extravasating into the left paracolic gutter, indicating an intraperitoneal component. Axial CT Cystogram: Lower down, perivesical contrast is seen. Foley catheter is present within the bladder. Axial CT Cystogram: Contrast extravasation localized around the right ureterovesical junction. Coronal CT Cystogram: Perivesical contrast around the dome of the bladder (blue arrow). Contrast is also demonstrated in the left paracolic gutter, indicating an intraperitoneal component (green arrow). Sagittal CT Cystogram: Defect in the bladder dome (yellow arrow) with perivesical contrast. Bladder Rupture Imaging Features • Intraperitoneal rupture – Contrast extravasates into the paracolic gutters and outlines loops of bowel. – Layering of contrast in dependent areas (Pouch of Douglas, Morrison’s Pouch) – Look for bladder dome defect • Extraperitoneal Rupture – Extravasation into extraperitoneal spaces, most commonly the retropubic space of Retzius – May see contrast extravasation into the anterior abdominal wall, thigh, and scrotum Bladder Rupture General Features • Extraperitoneal – 62% of all bladder ruptures – Usually secondary to pelvic fracture; fragment lacerates the base of the bladder. – Treatment is usually medical management with Abx and catheterization • Intraperitoneal – 25% of bladder ruptures – Trauma to abdomen with full bladder – May mimic acute renal failure – Treatment requires surgery to repair bladder dome • Combined – 12% of ruptures – Findings of both intraperitoneal and extraperitoneal ruptures References 1.

Anatomy of Pelvic Floor Dysfunction
Anatomy of Pelvic Floor Dysfunction Marlene M. Corton, MD KEYWORDS Pelvic floor Levator ani muscles Pelvic connective tissue Ureter Retropubic space Prevesical space NORMAL PELVIC ORGAN SUPPORT The main support of the uterus and vagina is provided by the interaction between the levator ani (LA) muscles (Fig. 1) and the connective tissue that attaches the cervix and vagina to the pelvic walls (Fig. 2).1 The relative contribution of the connective tissue and levator ani muscles to the normal support anatomy has been the subject of controversy for more than a century.2–5 Consequently, many inconsistencies in termi- nology are found in the literature describing pelvic floor muscles and connective tissue. The information presented in this article is based on a current review of the literature. LEVATOR ANI MUSCLE SUPPORT The LA muscles are the most important muscles in the pelvic floor and represent a crit- ical component of pelvic organ support (see Fig. 1). The normal levators maintain a constant state of contraction, thus providing an active floor that supports the weight of the abdominopelvic contents against the forces of intra-abdominal pressure.6 This action is thought to prevent constant or excessive strain on the pelvic ‘‘ligaments’’ and ‘‘fascia’’ (Fig. 3A). The normal resting contraction of the levators is maintained by the action of type I (slow twitch) fibers, which predominate in this muscle.7 This baseline activity of the levators keeps the urogenital hiatus (UGH) closed and draws the distal parts of the urethra, vagina, and rectum toward the pubic bones. Type II (fast twitch) muscle fibers allow for reflex muscle contraction elicited by sudden increases in abdominal pressure (Fig. -

The anatomy of the pelvic floor and its fascial components are currently poorly described and misunderstood. This systematic search and review aimed to explore and summarize the current state of knowledge on the fascial anatomy of the pelvic floor in women. Methods: A systematic search was performed using Medline and Scopus databases. A synthesis of the findings with a critical appraisal was subsequently carried out. The risk of bias was assessed with the Anatomical Quality Assurance Tool. Results: A total of 39 articles, involving 1192 women, were included in the review. Although the perineal membrane, tendinous arch of pelvic fascia, pubourethral ligaments, rectovaginal fascia, and perineal body were the most frequently described structures, uncertainties were Citation: Roch, M.; Gaudreault, N.; identified in micro- and macro-anatomy. -

If you have any further questions or concerns, please contact our office prior to your procedure so that we may clarify any pertinent issues. Definition: Retropubic Sling (SPARC) is a surgical procedure that uses a narrow strip of permanent mesh to correct stress urinary incontinence (SUI). This procedure is completed through the vagina and two small incisions on the lower abdomen just above the pubic bone; it creates stabilization and support for the urethra, the tube carrying urine from the bladder to the outside of the body. Once placed, the sling creates a V-shape that supports the urethra, therefore preventing urinary leakage during episodes of increased abdominal pressures, such as coughing, sneezing, or lifting. Procedure: After sedation from general anesthesia is achieved, a catheter is placed in the bladder. The surgeon will begin by making a small incision in the vagina under the urethra and two small incisions on the lower abdominal wall just above the pubic symphysis. -
