Psoas Muscle Edge Symptom

The symptom of the Edge of the Psoas Muscle is one of the signs of hydronephrosis, which is manifested by distortion of the shape of the X-ray shadow of the renal pelvis. In this case, the medial edge of the pelvis looks obliquely cut. This symptom is caused by displacement of the atonic wall of the renal pelvis by the lateral edge of the psoas major muscle.

Hydronephrosis is a disease in which the renal pelvis expands and the outflow of urine from the kidney is impaired. This can be caused by various reasons, such as poor blood supply to the kidney, stones in the urinary tract, or tumors.

The Psoas Muscle Edge symptom is an important sign of hydronephrosis and can be detected during an X-ray examination of the kidneys. It indicates the presence of compression of the renal pelvis by the lateral edge of the psoas major muscle.

It is important to note that the Psoas Muscle Edge Symptom is not the only sign of hydronephrosis and can be combined with other symptoms such as low back pain, urinary problems and high blood pressure. If such symptoms are detected, you should consult a urologist for diagnosis and treatment.

Thus, the Psoas Muscle Edge Symptom is an important sign of hydronephrosis, which can be detected by X-ray examination of the kidneys. If this symptom is detected, you must consult a doctor for diagnosis and treatment.



The psoas margin sign is one of the symptoms that can be detected during kidney and urinary tract examinations. This symptom manifests itself in a distortion of the shape of the renal pelvis on an x-ray, and its medial edge looks obliquely cut. This phenomenon is observed in hydronephrosis, which is a serious disease that leads to impaired kidney function. Today we will look at this symptom in more detail, find out its causes and how this symptom can help in diagnosing hydronephrosis.

What is Cray's sign?

Cray's sign occurs with the appearance of transmural ascending nephrosclerosis (TAN). This is a condition in which changes in the renal circuit are noted. The walls of the renal veins contract when high blood pressure occurs and are soon restored to their original state. Because of this, veins may reappear on the 9th day after blood pressure returns to normal. Later they become fibrotic and begin to lose their ability to stretch. Renal veins that have become severely constricted in response to high blood pressure may lie close to the renal arteries. Because fibrous veins obstruct blood flow, the kidneys work to the limit
