Ureteropelvic junction obstruction repair: when, how, what?
OBJECTIVE
To review factors that affect the success of ureteropelvic junction obstruction repair and recent developments in minimally invasive procedures for the repair of ureteropelvic junction obstruction.


RESULTS
Recent reports and studies further confirm earlier findings that the success rate of endopyelotomy is decreased when a crossing vessel is the primary cause of ureteropelvic junction obstruction, poor renal function and significant hydronephrosis. Various minimally invasive procedures have emerged recently for the treatment of ureteropelvic junction obstruction. These include laparoscopic pyeloplasty, robotically assisted laparoscopic procedures, and percutaneous endopyeloplasty. These procedures offer potential advantages over conventional endopyelotomy, including better success rates in the presence of crossing vessels, wider caliber reconstruction of the ureteropelvic junction, and full-thickness healing with primary intent.


CONCLUSIONS
With such a large variety of minimally invasive procedures for the treatment of ureteropelvic junction obstruction available, the treatment choice for ureteropelvic junction obstruction must be based on several factors, including the success and morbidity of the procedures, the surgeon's experience, the cost of the procedure, and the patient's choice.
