How does hydronephrosis drain out

Hydronephrosis can only be discharged by percutaneous nephrostomy or by treating the primary disease. Hydronephrosis is mainly caused by kidney disease itself, ureteral obstruction, lower urinary tract obstruction (such as prostatic hyperplasia) and other reasons, if the complications are more serious and complex, temporarily unable to treat the primary disease, can take percutaneous nephrostomy surgery to lead out the ponding, reduce the condition and symptoms of hydronephrosis, thus reducing the oppression of the kidney, but this is only expedient.

only active treatment of primary disease, the primary disease treatment, urination channel unobstructed, hydronephrosis will naturally be discharged along the ureter.
