URETEROSCOPIC ENDOPYELOTOMY IN AN ECTOPIC KIDNEY

A patient with an ectopic, pelvic kidney with congenital ureteropelvic junction obstruction was treated by retrograde, ureteroscopic endopye lotomy without percutaneous access. Preoperative ureteral stent placem ent and angiography facilitated the procedure. The patient had an unev entful recovery with improved drainage from the involved collecting sy stem demonstrated by renal scintigraphy 6 months postoperatively. Uret eroscopic endopyelotomy avoids the need for percutaneous access, which may be difficult in patients with ectopic, malrotated kidneys and app ears particularly well suited to the treatment of ureteropelvic juncti on obstruction in such cases.
