When there is salvageable renal function, treatment options include pyeloplasty and pyelotomy. Traditionally, open dismembered pyeloplasty has been the gold standard.
We report a rare case of an ante-grade malpositioned and extruded ureteral stent outside of the renal pelvis and its unique successful management via percutaneous antegrade nephroscopic holmium:yttrium aluminium garnet (YAG) laser pyelotomy - a procedure that has not been reported in the literature to date.
