Changes in Structure, Interstitial Cajal-like Cells and Apoptosis of Smooth Muscle Cells in Congenital Ureteropelvic Junction Obstruction
OBJECTIVE The goal of this study is to evaluate some structural changes in muscular, collagenous and neural components as well as expression of Cajal-like cells and apoptosis of smooth muscle cells in congenital ureteropelvic junction obstruction (UPJO). METHODS Tissue specimens were obtained from 25 patients with UPJO and compared with normal ureteropelvic junction regions of 19 autopsies. I...
متن کاملRenal osteodystrophy secondary to congenital bilateral ureteropelvic junction obstruction.
A 4-year-old girl presented with progressive distension of the abdomen and bowing of the legs (genu valgum) since birth. She was anemic, with a blood pressure of 180/110 mmHg. The serum level of creatinine was 1.7 mg/dL. She had hypocalcemia, and elevated serum level of phosphorous and parathyroid hormones. Ultrasonography revealed bilateral grossly hydronephrotic kidneys with thinned out paren...
متن کاملResults of Pyeloplasty in patients with Ureteropelvic Junction Obstruction in Pediatric Surgery Center in Bandar Abbas
Introduction: Ureteropelvic junction obstruction (UPJO) is associated with inadequate urine drainage from renal pelvis into ureter. UPJO results from incomplete recanalization of proximal ureter during fetal period which finally leads to hydrostatic distention of renal pelvis and calyces. Diagnosis is based on clinical symptoms, ultrasound, and diuretic isotopic renogram. Various surgical metho...
متن کاملCongenital Ureteropelvic Junction Stenosis
Introduction Congenital ureteropelvic junction (UPJ) stenosis is a disturbance in the flow of urine at the crossover point from the kidney pelvis to the ureter, with a dilatated and obstructed renal-pelvic calyceal system (Figure 89.1). UPJ obstruction is the most frequent congenital malformation of the genitourinary system. Its incidence is around 1 out of 1,000 newborns. The first sonographic...
متن کاملDelayed maturation of interstitial cells of Cajal in meconium obstruction.
BACKGROUND/PURPOSE The etiology of meconium obstruction without cystic fibrosis is unclear. Interstitial cells of Cajal (ICC) function as pacemakers in gut motility and may play a role in the pathophysiology of the disease. METHODS The ICC were examined by immunohistochemical staining with anti-c-kit antibody in the bowel walls of 6 neonates who had meconium obstruction without cystic fibrosi...
