We have reported diagnosed preoperatively in 41 years old male with complaints of intermittent right flank pain, with gross hematuria, urinary frequency, nocturia, tenesmus, and high fever. I.V.P. revealed delayed dye excretion on the right side with pyelocalyectasis and ureterectasis of upper ureter and stenotic portion beneath ureter was non visualization. R.G.P. revealed same as I.V.P. and right ureter was `sickle shape` course and its descent alonged over the right side of 4th and 5th lumbar vertebra column. On post operation 8th days, I.V.P. revealed slightly reduced of previous marked dilated right pelviocalyceal system with upper ureter and preoperative placed ureter was corrected to normal course.
