What are the treatment of hydronephrosis? We have a lot of people do not know what is hydronephrosis, hydronephrosis patients will lead to urinary tract infection, because the hydronephrosis patients urine will arrest in patients with renal and ureteral calculi, this environment is the most conducive to bacterial reproduction, but also concurrent patients pyelonephritis and ureteritis.

1, segmental function: due to ureteropelvic junction or upper ureteral segmental muscle agenesis and hypoplasia or anatomical structure disorder, affecting the normal peristalsis of the ureter, causing obstruction of power. Such lesions, such as at the entrance of the ureter and bladder, form a congenital ureter, which results in the expansion of the kidney and ureter.

2, intrinsic ureteral stricture: mostly occurred in the pelvis and ureter junction, narrow segment usually is 1 ~ 2mm, also can be up to 1 ~ 3cm, produce incomplete obstruction and secondary distortion. Under the electron microscope, excessive collagen fibers can be seen in the middle of the obstructed segment muscle cells and around cells, long muscle cells are damaged, the formation of stenosis mainly collagen inelastic hinders urine transmission. Hydronephrosis.

3, ureteral distortion, adhesion, band or PEG valve structure: this can be congenital or be acquired, at the junction of the lumbar segment of ureter and renal pelvis and ureter often occurs in children and infants, accounted for almost 2/3.

4, ectopic vascular compression at ureteropelvic junction in front of the other, with a horseshoe kidney and embryo kidney hindered rotation etc..

5, ureteral high opening: may be congenital, but also because of peripelvic renal fibrosis or vesicoureteral reflux caused by asymptomatic hydronephrosis, cause ureteropelvic junction sites relative to the transfer in the operation can not be found stenosis.

6 patients also have renal atrophy, mainly due to patient eduction, this time the pelvis will expand, will increase the inner pressure of kidney, renal tissue blood vessels will cause renal ischemic compression, patients with progressive atrophy, renal failure and damage. Patients with severe general atrophy of renal tissue is difficult to repair, and that will cause a huge hydronephrosis, this time is very easy to cause patients with traumatic rupture or spontaneous rupture, serious threat to the lives of patients.
