Hydronephrosis is a condition that typically occurs when a kidney becomes enlarged due to the absence of the normal drainage of urine from the kidney to the bladder itself. The swelling most commonly affects only one kidney, but both kidneys may be affected. Hydronephrosis is not a disease but a structural condition: it is the result of a blockage or obstruction in urinary tract. Although the condition occurs in about 1 in 100 adults, it is quite common in children. according to the Boston Children's Hospital, hydronephrosis affects about one person in 500 (BHC).
causes
The hydronephrosis is not a real disease, but can be caused by a number of internal and external conditions that affect the kidneys and the renal system of urine collection.

The treatment chosen by the doctor depends on the cause of the obstruction;
if the condition was caused by a dependent block ureter, you may perform the following procedures:
Insertion of a ureteral stent (a tube that allows to empty the ureter into the bladder)
Insertion of a nephrostomy tube (which allows urine to flow through the blocked back)
Antibiotics to fight infection
It is possible that the doctor decides to remove the obstruction by means of a surgical intervention. If the obstruction is due to scar tissue or a blood clot, or similar causes, it is possible that the affected area is removed completely. The surgeon can then reconnect the healthy ureter ends to restore the normal flow of urine.
If the cause of hydronephrosis is a kidney stone, you may need surgery to remove it. A possible kidney stone can be removed endoscopically using small surgical instruments that allow the surgeon to drill smaller incisions and drastically reduce the time required for healing and convalescence. Your doctor may also prescribe low doses of antibiotics to help prevent the development of kidney
