What are the causes of hydronephrosis? Hydronephrosis is a common type of kidney disease. There are many reasons for hydronephrosis, and patients should be diagnosed before treatment. Below, I have introduced the etiology of hydronephrosis, hoping to help everyone.
What are the causes of hydronephrosis?
1、 Congenital factors
1. What are the causes of hydronephrosis? "At the entrance to the ureter and bladder, if there is a dynamic obstruction due to segmental muscle deficiency, hypoplasia, or anatomical structure disorder at the junction of the renal pelvis and ureter, or in the upper ureter, congenital megaureter can form, with the consequences of renal and ureteral dilatation and hydrops.".
2. What are the causes of hydronephrosis? "There are excessive collagen fibers around and between the muscle cells in the obstructive segment. Over time, the muscle cells are damaged, forming an inelastic narrow segment dominated by collagen fibers, which hinders the transmission of urine and forms hydronephrosis.".
2、 Acquired obstruction
1. Post-inflammatory or ischemic scars lead to local fixation. Stone and trauma, as well as scar narrowing after trauma.
2. Neoplasms such as tumors and polyps in the renal pelvis and ureter may be primary or metastatic.
3. What are the causes of hydronephrosis? "Cystoureteral reflux causes ureteral distortion, coupled with periureteral fibrosis, which ultimately leads to obstruction of the ureteropelvic junction or ureter.".
3、 The causes of hydronephrosis also include lesions in arteries and veins, lesions in the female reproductive system, pelvic tumors, and inflammation; Gastrointestinal lesions, retroperitoneal lesions, and so on.
