<prompt> According to Weige Meyer rule of duplication of ureter, the lower pole ureter in urinary bladder is:Lateral and cephalad to the upper pole ureterLateral and caudal to the upper pole ureterMedial and cephalad to the upper pole ureterMedial and caudal to the upper pole ureter  <response>: Types Incomplete duplication: Both ureters join together and a single ureteric opening Complete duplication: Both ureters open separately Weige-Meyers rule: - In case of complete duplication, the upper ureter and the lower pole ureter rotate on their long axes so that the upper pole ureteric orifice is medial caudal to the lower pole orifice. - Lower pole is lateral and cephalad to the upper pole
