Obstruction in Children," Urology, vol.
With shorter hospital stay and better cosmetic results, laparoscopic dismembered pyeloplasty has the potential to replace open surgery and, provided there is availability of expertise, it should be considered the first option for the treatment of ureteropelvic junction
Percutaneous surgery for ureteropelvic junction
obstruction (endopyelotomy): Technique and early results.
In a study of 213 children with mild to moderate hydronephrosis, there was a 39% significantly obstructive uropathy (ureteropelvic junction
obstruction, vesicoureteral stenosis, and posterior urethral valves) (11).

Clinical indication for endoscopic biopsy included bladder tumor (n = 36), ureteral tumor (n = 21), nephrolithiasis (n = 13), renal tumor (n = 13), hydronephrosis (n = 12), hematuria (n = 11), ureteropelvic junction
obstruction (n = 4), ureteral stricture (n = 2), and ureteral obstruction (n = 2), with a few cases in which an indication was not provided (n = 4).

Following diagnosis and successful treatment of the UTI, the doctor may order tests to detect abnormalities such as vesicoureteral reflux (backflow of urine from bladder to ureter and/or kidneys), ureteropelvic junction
blockage (thinning or blockage of the junction of ureter and kidney), ureterovesicular junction blockage (blockage of the junction of ureter and bladder), and urethral blockage.
Bilateral traumatic lumbar hernias with injuries of the right renal pelvis and ureteropelvic junction
Renal ultrasound, for example, detected a left ectopic ureter with a right ureteropelvic junction
obstruction in a duplicated system bilaterally.
