Presented here is the case of a minimally invasive percuta- neous antegrade approach that should be considered. Multi-length ureteral stents are indicated in many benign and malignant urological pathologies. Complications include stent irritation, encrustation, knot- 1,2 ting, and migration. Predictors of proximal stent migra- tion include low stent-to-ureter length ratio based on ureterovesical-to-ureteropelvic junction measurement, upper calyx placement of the proximal stent curl, and proximal migration may also be related to the degree of 3,4 proximal stent curl, and increased indwelling time. Measurement of actual ureteral length can be estimated by height, body habitus, imaging such as intravenous pyelog- raphy, or directly measured with a guidewire or ureteral catheter.
