Urinary tract obstruction resulting from ureteropelvic junction obstruction or strictures within the ureter or urethra can be challenging conditions to manage effectively. With careful patient selection and proper technique, endoscopic incisions, including endopyelotomy, endoureterotomy, and visual urethrotomy, can be valuable treatment options. Endoscopic management offers the advantage of reduced operative morbidity and postoperative recovery with acceptable success rates. This chapter will cover the indications, equipment, and techniques of endopyelotomy, endoureterotomy, and visual urethrotomy.
