What reason is hydronephrosis caused

summary

The kidney is a very important organ in our body, we should pay attention to protect it at ordinary times, otherwise it is easy to appear abnormal, many people will have hydronephrosis, what is the reason for this? Now let me introduce it to you.

What reason is hydronephrosis caused

* first, the appearance of hydronephrosis is actually due to the expansion of the renal pelvis and calyx caused by obstruction of the urinary system, and the retention of urine is collectively called hydronephrosis. The main cause of hydronephrosis is ureteropelvic junction obstruction.

Second, some adverse external factors caused their own hydronephrosis, obstruction caused by foreign lesions, including artery and vein lesions; Female reproductive system diseases; Pelvic tumor and inflammation; Gastrointestinal diseases; Retroperitoneal lesions

Third, the normal peristalsis of this segment of ureter is affected by segmental muscle absence, hypoplasia or anatomical structure disorder at the junction of renal pelvis and ureter, resulting in dynamic obstruction. If the lesion occurs at the entrance of ureter and bladder, congenital megaureter will be formed, resulting in renal and ureteral dilatation and hydronephrosis.

matters needing attention

Because of the accumulation of urine in the kidney, the pressure increases, so that the renal pelvis and calyces expand and renal parenchyma atrophy. If the retention urine is infected, it * s called infectious hydronephrosis.
