What causes hydronephrosis

Hydronephrosis is a common urinary system disease, which may be caused by congenital abnormalities, urinary system infections, kidney stones or tumors, urethral meatus stenosis or atresia.

1.

Congenital abnormalities in infants at birth can lead to abnormal kidney development, resulting in hydronephrosis.

2. Urinary system infections

can cause urethral stricture, which hinders urination. Long-term poor urination can lead to hydronephrosis.

3. Kidney stones or

tumors can block urinary tract drainage, causing hydronephrosis.

4. Urinary meatus stenosis

or atresia can lead to urinary drainage difficulties, resulting in hydronephrosis.
