Newborn hydronephrosis right 1.4, left 1.1 what to do

Patient's question:

Kidney hydronephrosis on both sides for 45 days

Doctor's answer:

1. Remove the cause, relieve obstruction.
2. If the condition is too severe or the cause is complex, percutaneous renal drainage can be performed first.
3. In cases of severe hydronephrosis or pyonephrosis with good function of the contralateral kidney, nephrectomy should be performed.
4. For patients who cannot undergo surgical resection, a double "T" tube or stent tube can be placed.
