How is obstructive nephropathy caused?

summary

If the obstruction does not affect the renal parenchyma, it is generally not called obstructive nephropathy, but obstructive uropathy. Hydronephrosis is usually the clinical manifestation of obstructive nephropathy, but many obstructive nephropathy (such as intrarenal obstruction) do not necessarily have hydronephrosis. At the same time, many cases, especially congenital ureteral malformation, can have renal pelvis dilation, but not necessarily hydronephrosis. How is obstructive nephropathy caused? Let's talk about it

How is obstructive nephropathy caused?

Ureter itself, as well as outside the ureter. Ureter itself can be divided into two categories: obstruction in cavity and obstruction of ureter wall. Calculus is the most common cause of intraluminal obstruction. It can occur in any part of the ureter, but most often in the natural turning or stenosis, or in the small lumen of the kidney. Renal calculi are usually caused by metabolic disorders, such as uric acid crystallization or taking sulfonamides with poor solubility

The dysfunction of ureteral wall itself can be divided into functional and anatomical abnormalities. The former is often caused by the abnormal operation of the running muscle in the ureter, and can be caused by the obstruction of the longitudinal or circular running muscle of the ureter, resulting in the abnormal descending of urine. In the ureteropelvic junction is more, in children are mostly bilateral, the left kidney is often more serious, so the performance is often more prominent. In the other group, ureterovesical junction disorders were mainly male, mostly unilateral.

Urinary tract obstruction caused by bladder dysfunction is mostly neurogenic, which can be caused by congenital muscular dysplasia or spinal cord dysfunction. Acquired diabetes is common in diabetes, cerebrovascular disease, multiple sclerosis or Parkinson's disease. Ureteral wall lesions caused by anatomical lesions include stricture caused by inflammation and tumor. Obstruction outside the urinary tract is often caused by the reproductive system, gastrointestinal system, and other vascular or retroperitoneal lesions.
