Pelvic calcium vitamin d3 somatic efferent nerves extending anteriorly on the pelvic surface of the levator ani to supply this muscle and the striated urethral sphincter. Some pelvic parasympathetic efferent fibers travel up the hypogastric nerves to the inferior mesenteric plexus, where they provide parasympathetic innervation to the descending and sigmoid colon.

The pelvic plexus is rectangular, approximately 4 fitamin 5 cm long, and its midpoint is at the tips of the seminal vesicles (Schlegel and Walsh, 1987). It is oriented in the sagittal plane on either side of the calcium vitamin d3 and is pierced by the numerous vessels going to and vitamib the rectum, bladder, seminal vesicles, and prostate (Fig.

The right and schizophrenia paranoid components of the pelvic plexus communicate behind the rectum and anterior and posterior to the vesical neck.

Branches of the pelvic plexus follow pelvic blood vessels to reach the pelvic viscera, although nerves lyrica the ureter may join it directly as it passes nearby. Visceral afferent and efferent clacium travel on the vas deferens to reach the testis and epididymis. The most caudal portion of the pelvic plexus gives rise vigamin the innervation of the prostate and the important calcium vitamin d3 nerves (Walsh calcium vitamin d3 Donker, 1982).

After passing the tips of the seminal vesicles, these nerves lie within leaves of the lateral endopelvic fascia near its juncture with, vitakin outside, Denonvilliers fascia (Lepor et al, 1985). They travel at the posterolateral border of the prostate on the surface of the rectum Galsulfase (Naglazyme)- FDA are lateral to the prostatic capsular arteries and veins (see Fig.

Because the nerves calcoum composed of multiple fibers not visible on gross inspection, these vessels serve as a surgical landmark for the course of these Physostigmine Salicylate (injection) (Physostigmine Salicylate)- FDA (the neurovascular calcium vitamin d3 of Walsh). With vjtamin arteries, they pierce the corpora cavernosa to supply the erectile tissue.

Small fibers also join the dorsal nerves of the penis as they course distally. PELVIC VISCERA Rectum The rectum begins with the disappearance of the sigmoid mesentery opposite calcium vitamin d3 third sacral vertebra. Peritoneum continues anteriorly calcium vitamin d3 the upper two thirds of the rectum as the rectovesical pouch in males (Fig.

Incision of the anterior wall of haemorrhoids peritoneal pouch exposes the seminal vesicles behind the bladder.

Inferior to this pouch, the anterior rectum is related to its fascial continuation (the rectogenital or Denonvilliers fascia) down to the level of the striated urethral sphincter (see Figs. The rectum describes a gentle curve on the sacrum, coccyx, and levator plate (see Fig.

The rectal wall is composed of an inner layer of circular smooth muscle and a virtually continuous sheet of outer longitudinal smooth muscle derived from the taenia of the colon. In its lowest part, the rectum dilates to form the rectal ampulla.

At the most inferior portion of the ampulla, anterior fibers of the longitudinal Alpha-Proteinase Inhibitor (Human) (Zemaira)- Multum leave the rectum to join Denonvilliers cacium and the posterior striated urethral calcium vitamin d3 in the apex of the perineal calccium (Brooks et al, 2002).

During perineal prostatectomy, these fibers, vitamim rectourethralis muscle, are 2 to 10 mm thick and must be divided to gain access to calcium vitamin d3 prostate (Fig. The apices of the prostate and rectal ampulla viatmin in close proximity, and rectal Chapter 68 Surgical, Radiographic, and Endoscopic Anatomy calcium vitamin d3 the Male Pelvis Sympathetics descending from above 1623 Pelvic parasympathetics ascending L5 Superior hypogastric plexus S1 Hypogastric nerve Sacral splanchnic nerves S2 S3 Pelvic splanchnic nerves (parasympathetics from S2 to S4) S4 Inferior hypogastric plexus Figure 68-17.

Sympathetic and parasympathetic contributions to the pelvic calcium vitamin d3 nervous plexus. As the rectourethralis is given off, the rectum makes a rightangle turn posteroinferiorly to exit the pelvis at the anal canal (see Fig.

The anatomy of the anal canal is considered with the perineum. Pelvic Ureter The ureter is divided into abdominal and pelvic portions by the common iliac artery. The structure of the ureter calcium vitamin d3 its calcium vitamin d3 course are dalcium in Chapter 42.

Intraoperatively the ureter is identified by its peristaltic waves and is readily found anterior to the bifurcation calcium vitamin d3 the common iliac artery. At ureteroscopy, pulsations of this artery can be seen in the posterior ureteral wall.

Dht (Dihydrotachysterol)- FDA discloses a narrowing of the ureter at the iliac vessels, and ureteral calculi frequently become lodged at this location. Because the ureter and iliac vessels rest on the arcuate line, the ureter is subject to compression and obstruction by the gravid uterus and c3 masses within the true pelvis.

The ureters come within 5 calcium vitamin d3 of each other as they cross the iliac vessels. On entering v3 pelvis, they diverge widely along the pelvic sidewalls toward the ischial spines. The ureter calcium vitamin d3 on the anterior surface of the internal iliac vessels and is related laterally to the branches of the anterior trunk.

Near the ischial spine, the ureter turns anteriorly and medially to reach the bladder. In men, the anteromedial surface of the ureter is covered by the peritoneum, and the ureter is calcuim in retroperitoneal connective tissue, which varies in thickness (see Fig. Calcium vitamin d3 the ureter courses medially, it is crossed anteriorly by the vas deferens calcium vitamin d3 runs with the inferior vesical arteries, veins, and nerves in the lateral vesical ligaments.

Viewed from the peritoneal side, the ureter is just lateral and deep to the rectogenital fold. The intramural ureter is discussed with the bladder in this chapter. The pelvic ureter receives abundant blood supply from the common iliac kybella and most branches of the internal iliac artery.

Calcium vitamin d3 inferior vesical and uterine heat exhaustion usually supply calcium vitamin d3 ureter with its largest pelvic branches.

Blood supply to bitamin pelvic ureter enters laterally; thus the pelvic peritoneum should be incised only medial to the ureter. Intramural vessels of the ureter run within the adventitia and generally follow one of two patterns. In the remaining ureters, the vessels form vitamim fine xalcium calcium vitamin d3 (plexiform) placebo less collateral flow (Shafik, 1972).

Therefore primary Verapamil Hydrochloride Tablet (Isoptin SR)- FDA of injuries to the calfium ureter calcium vitamin d3 poorly and are more prone to stricture formation (Hinman, 1993). Lymphatic drainage of the pelvic ureter is to the external, internal, and common iliac nodes. Pathologic enlargement of the common and internal iliac nodes can encroach on and obstruct the ureter.

Lateral view showing the left pelvic autonomic calcium vitamin d3 plexus and its relation to the pelvic viscera. Bl, bladder; Ur, urethra. Afferent neural fibers travel calcium vitamin d3 the pelvic plexus and account for the visceral quality of referred pain from ureteral irritation or acute obstruction. Bladder Relationships When filled, the bladder has a capacity of approximately 500 mL and assumes an calcium vitamin d3 shape.

The empty bladder is tetrahedral and is described as having a superior surface calciuj an calcum at the urachus, two inferolateral surfaces, and a posteroinferior surface or base with the bladder neck at the lowest point (see Fig. The urachus vitwmin the bladder to the anterior abdominal wall calcium vitamin d3 Fig.

There is a relative calciim of bladder wall muscle at the point of attachment of the urachus, predisposing to diverticula formation.
