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.
In pregnancy, dextrorotation (rotation to the right) of the uterus can cause compression on the right ureter, thus making hydronephrosis more common in the right kidney than in the left kidney. Besides, hormones such as estrogen, progesterone, and prostaglandin can cause ureter dilatation, thus causing hydronephrosis despite the absence of ...
A pelvic kidney, also known as an ectopic kidney, is a normal kidney located in the pelvis, instead of the abdomen. This occurs when a kidney does not ascend from its original location in the pelvis to its final location during prenatal development. They usually present no symptoms, but can increase risk of certain illnesses and healthcare problems
The kidney is surrounded by tough fibrous tissue, the renal capsule, which is itself surrounded by perirenal fat, renal fascia, and pararenal fat. The anterior (front) surface of these tissues is the peritoneum, while the posterior (rear) surface is the transversalis fascia. The superior pole of the right kidney is adjacent to the liver.
Pyelectasis is a dilation of the renal pelvis.It is a relatively common ultrasound finding in fetuses and is three times more common in male fetuses. In most cases pyelectasis resolves normally, having no ill effects on the baby.
Pyonephrosis (from Greek pyon 'pus' and nephros 'kidney' [1]) is a dangerous kidney infection that is characterized by pus accumulation in the renal collecting system. [2] It is linked to renal collecting system blockage and suppurative renal parenchymal destruction, which result in complete or nearly complete kidney failure. [3]
Nephroptosis is rare and abnormal condition in which the kidney drops down (ptosis) into the pelvis when the patient stands up. It is more common in women than in men. It has been one of the most controversial conditions in terms of both its diagnosis and its treatments.
The renal calyces (sg. calyx) are conduits in the kidney through which urine passes. The minor calyces form a cup-shaped drain around the apex of the renal pyramids.Urine formed in the kidney passes through a renal papilla at the apex into the minor calyx; four or five minor calyces converge to form a major calyx through which urine passes into the renal pelvis (which in turn drains urine out ...
