obstruction: analysis of 593 patients in a prospective national database," World Journal of Urology, vol.
In our manuscript, we report the case of a 15-year-old boy with a longstanding history of unilateral ureteropelvic junction
obstruction who was presented for right flank pain of three-month duration.
obstruction (UPJO) is a condition where flow of urine from the renal pelvis to the proximal ureter is hindered.
The role of percutaneous endopyelotomy for ureteropelvic junction
Therefore, this study aimed to evaluated laparoscopic ureterocalicostomy as treatment of experimental ureteropelvic junction
(UPJ) obstruction in pigs.
We performed a computed tomography (CT) scan of the patient's abdomen, which revealed bilateral hydronephrosis secondary to ureteropelvic junction
stenosis: vascular anatomical background for endopyelotomy.
Moderate and severe cases with diameters greater than 15 mm (grades 3 and 4) are often associated with ureteropelvic junction
obstruction, posterior urethral valves, and vesicoureteral reflux (VUR); mild cases (grades 1 and 2) mostly resolve spontaneously (7).
The management of congenital ureteropelvic junction
(UPJ) obstruction has evolved over the past 20 years.
Congenital anomalies of the kidney and urinary tract (CAKUT) comprise a spectrum of malformations that occur at the level of the kidney (e.g., hypoplasia and dysplasia), collecting system (e.g., idiopathic hydronephrosis, ureteropelvic junction
obstruction, and megaureter), bladder (e.g., ureterocele and vesicoureteral reflux), or urethra (e.g., posterior urethral valves) .
Calculi locating in proximal ureters which were from ureteropelvic junction
to the upper edge of the pelvis would be considered to be treated with LU.
