What causes hydronephrosis in both kidneys

The occurrence of bilateral hydronephrosis may be related to factors such as urinary tract stones, urogenital tumors, prostate hyperplasia, etc. The specific analysis is as follows:

1. Urinary tract stones The

stones in the renal calyx, ureter, bladder, urethra and other parts will cause urinary tract obstruction, resulting in poor urine discharge, so that urine accumulates in the urinary system, causing bilateral hydronephrosis.

2. Urinary reproductive system tumors

Kidney cancer, renal pelvis cancer, ureter cancer, penile cancer and other diseases will lead to obstruction of urinary tract patency, affecting urine discharge, resulting in increased kidney pressure, causing bilateral hydronephrosis.

3. Prostatic hyperplasia

occurs after prostatic hyperplasia, prostate volume increases, compression urethra, resulting in poor urination, urine retention in the bladder, resulting in increased kidney pressure, so that renal parenchyma atrophy, renal function decline, resulting in bilateral hydronephrosis.
