In the lower part of the abdomen, the right ureter sits behind the lower mesentery and the terminal ileum, and the left ureter sits behind the jejunum and the sigmoid colon. [2] As the ureters enter the pelvis, they are surrounded by connective tissue, and travel backward and outward, passing in front of the internal iliac arteries and internal ...
The Okabayashi space (or medial division of the pararectal space) is an anatomical potential space in the pelvis. [ 1 ] The ureter divides the pararectal space into the Okabayashi space medially and the Latzko space laterally.
Ultrasound of the urinary tract is performed by a probe placed on the abdominal wall, called a transducer. [1] This occurs while a person is lying down. [1] It is then moved around to better visualise different parts of the urinary tract. [1] Gel is used on the abdominal wall, allowing smooth movement and improve sound conduction. [1]
The renal pelvis is the location of several kinds of kidney cancer and is affected by infection in pyelonephritis. [citation needed] A large "staghorn" kidney stone may block all or part of the renal pelvis. The size of the renal pelvis plays a major role in the grading of hydronephrosis.
The pelvic cavity is a body cavity that is bounded by the bones of the pelvis. Its oblique roof is the pelvic inlet (the superior opening of the pelvis). Its lower boundary is the pelvic floor. The pelvic cavity primarily contains the reproductive organs, urinary bladder, distal ureters, proximal urethra, terminal sigmoid colon, rectum, and ...
In placental mammals, urine enters the bladder via the ureters and exits via the urethra during urination. [1] [2] In humans, the bladder is a distensible organ that sits on the pelvic floor. The typical adult human bladder will hold between 300 and 500 ml (10 and 17 fl oz) before the urge to empty occurs, but can hold considerably more. [3] [4]
The vesicouterine pouch is a fold of peritoneum over the uterus and the bladder, forming a pelvic recess. [1] It is continued over the intestinal surface and body of the uterus onto its vesical surface, which it covers as far as the junction of the body and cervix uteri, and then to the bladder.
IVP was previously the test of choice for diagnosing ureter obstruction secondary to urolithiasis but in the late 1990s non-contrast computerized tomography of the abdomen and pelvis replaced it because of its increased specificity regarding etiologies of obstruction. [17]
