Introduction The performance of robot‐assisted laparoscopic pyeloplasty has recently been increasing in frequency. However, patients with duplicated renal pelvises and ureters can present challenges. Case presentation A 71‐year‐old woman presented flank pain was diagnosed ureteropelvic junction obstruction an incomplete collecting system. Preoperative imaging did not reveal the details stenosis...

Objective: The aim of this study was to scintigraphically investigate the preoperative and postoperative renal functions patients operated due ureteropelvic junction obstruction, discuss factors affecting indication surgery emphasize important points consider during scintigraphic examination. Method: We retrospectively analyzed pediatric cases who underwent pyeloplasty obstruction. Patients for...

background : hydronephrosis (hn) or calycial dilatation is the most common prenatal urologic abnormality. the aim of this study was to identify the possible changes in demographic and clinical manifestations of infantile hn in previously and recently diagnosed patients.   methods : 193 children with infantile hn admitted to ali-asghar children's hospital in two different periods (group 1 1997-2...

PURPOSE It is thought that the 3 narrowest points of the ureter are the ureteropelvic junction, the point where the ureter crosses anterior to the iliac vessels and the ureterovesical junction. Textbooks describe these 3 sites as the most likely places for ureteral stones to lodge. We defined the stone position in the ureter when patients first present to the emergency department with colic. ...

BACKGROUND AND OBJECTIVES We aimed to assess the feasibility and outcomes of complex ureteropelvic junction obstruction cases submitted to robotic-assisted laparoscopic pyeloplasty. METHODS The records of 131 consecutive patients who underwent robotic-assisted laparoscopic pyeloplasty were reviewed. Of this initial population of cases, 17 were considered complex, consisting of either atypical...

Congenital obstructive nephropathy is the principal cause of renal failure in infants and children. The underlying molecular and cellular mechanisms of this disease, however, remain largely undetermined. We generated a mouse model of congenital obstructive nephropathy that resembles ureteropelvic junction obstruction in humans. In these mice, calcineurin function is removed by the selective del...
