Endoscopic Dilation-Endopyelotomy 



What is Endopyelotomy?

Endopyelotomy is an endoscopic procedure to treat ureteropelvic junction (UPJ) obstruction. The kidney is either approached through the Percutaneous Nephrostomy tube (from the side i.e. Antegrade Endopyelotomy) or through the urethra and urinary bladder (Retrograde Endopyelotomy). Endopyelotomy relieves the obstruction in the upper part of the ureter called the renal pelvis.

Why is Endopyelotomy performed?

Obstruction of the ureteropelvic junction (UPJ) can be caused by congenital abnormalities like horseshoe kidney, fibrous scarring due to stone or previous operation, a blood vessel which may kink the UPJ or a stone that gets impacted in the upper part of ureter. This can cause damage to kidney tissue and eventually lead to pain, stone formation, infection, high blood pressure, deterioration of kidney function and eventually kidney failure. Endopyelotomy is a popular procedure to relieve all these symptoms.
