Abstract

Introduction: Ureteropelvic junction obstruction (UPJ obstruction) is the insufficient expulsion of urine

from renal pelvis to ureter which is caused by a congenital or acquired pathologies. MAG-3 or DTPA renal

scintigraphy and rarely Whitaker test are used for the diagnosis of this disease. Open, endourologic or

laparoscopic techniques can be used for the treatment of the disease. Percutaneous endopyelotomy, cautery

balon endopyelotomy, ureteroscopic endopyelotomy or laparoscopic pyeloplasty are the techniques which can

be used. Each of these techniques has both advantages and disadvantages. In this review, we evaluated the

advantages, disadvantages, success rates and complications of endourological techniques with the support of

the current literature.
