Position of kidneys, urinary and genital organs

in the female (anterior aspect, schematic drawing).

The excursions of the kidneys with the respiratory

movements of the diaphragm are indicated.

Retroperitoneal organs of the female (anterior aspect). View of

the female pelvis showing uterus with uterine ligaments, ovary, and

urinary bladder (from Lütjen-Drecoll, Rohen, Innenansichten des

menschlichen Körpers, 2010).

The organs of the urinary system (kidney, ureter,

and, in the female, genital organs ) are located

together with vessels and nerves (aorta, inferior

vena cava, plexus solaris, etc.) within the retroperitoneal space.

The upper part of the kidneys reaches the level

of the margin of the lung. During respiration,

the kidneys move slightly within their fasciae of

Gerota. Parallel with the vertebral column, the

ureter runs towards the urinary bladder. The

great center of the autonomic nervous system,

the solar plexus (celiac ganglion, etc.), is located

in front of the abdominal aorta.

The genital organs of the female (uterus,

uterine tube, ovary) are located within the

pelvic cavity. In the male, the testis has moved

out of the abdominal cavity and penetrated the

inguinal canal to be finally located within the

extragenital organs.

324 Position of the Urinary Organs

Horizontal section through the abdominal cavity at the level of the first lumbar vertebra

(from below).

Positions of urinary organs (posterior aspect, schematic drawing).

Notice that the upper part of the kidney reaches the level of the

margin of pleura and lung.
