Three-Dimensional Laparoscopic Management of Primary Obstructive Megaureter

Abstract

Abstract Introduction and Objective: Megaureter (MGU) is a disease including variable anomalies. It may be caused by either a primary cause or secondary to specific pathologic origin. The cause of primary obstructive MGU typically is an aperistaltic juxtavesical segment 2 or 3 cm long that is unable to propagate urine at acceptable rates of flow. The result of lower ureteral obstruction can lead to renal failure due to silent obstruction of the ureter and can be complicated by potential loss of renal function. We present a video demonstration of three-dimensional (3D) laparoscopic management of primary obstructive megaureter. Materials and Methods: Case 1: A 7-year-old male with h/o right dull loin pain and recurrent urinary-tract infection (UTI) on and off for 1 year. Imaging protocol included ultrasound (USG), micturating cystourethrogram, and MRI, which revealed grossly dilated tortuous ureter with obstruction at the right vesicouretral junction (VUJ). Laparoscopic tailored reimplantation was performed...
