Ultrasound show dilation kidney but it far from accurate diagnosis. diagnosed intravenous pyelography (IVP), computed tomography urography (CTU) magnetic resonance (MRU). Mild hydronephrosis good excretory times followed without surgical intervention. But severe should corrected surgery. treatment involves excision part bringing anterior by ureteroureteral ureteropelvic anastomosis. Open, laparoscopic robotic surgeries different modalities. Transperitoneal retroperitoneal approaches options for In this paper we report case managed ureteroureterostomy.
