uretero pelvic junction (upj) obstruction is a common cause of hydronephrosis in infants. the frequent use of fetal ultrasound is allowing early (prenatal) diagnosis of numerous uropathies previously delayed until the child either became symptomatic or had a palpable mass. newborn with severe obstruction often has marked improvement following correction, therefore, early diagnosis and operation...
conclusions the severity of pathological changes in renal parenchyma, due to upjo, is a good predictor of renal function recoverability, after pyeloplasty. the orus, with drf > 35%, usually have normal (grade i) renal biopsy and might be expected to present better functional recoverability after pyeloplasty. results this study showed a linear relationship between the severity of histological ch...
BACKGROUND Percutaneous nephrolithotomy is a well known therapeutic modality for stone diseases of childhood. Antegrade and retrograde endopyelotomies are also well defined options of treatment for secondary ureteropelvic junction obstruction. Yet there are few reports regarding endoscopic therapy of intrinsic ureteropelvic junction obstruction. To our knowledge, there exist only a few reports ...
PURPOSE We report our experience with auto-expandable metallic stents for treating ureteropelvic junction obstruction. MATERIALS AND METHODS We treated 4 patients with a mean age of 45 years who had ureteropelvic junction obstruction with placement of a self-expandable intraureteral metallic stent (Wallstent, Schneider, Zurich, Switzerland). All patients presented with recurrent ureteropelvic...
Purpose: To determine the importance of MRI with contrast-enhanced MRA for the detection or exclusion of aberrant or obstructing renal arteries in ureteropelvic junction obstruction in children. Materials and Methods: Key word-based search in RIS database (ureteropelvic junction obstruction/ MRI) and retrospective comparison of arterial findings from preoperative contrast -enhanced MRA and intr...
BACKGROUND Laparoscopic pyeloplasty is rapidly becoming an acceptable procedure for ureteropelvic junction obstruction in the pediatric population. We present our experience with transperitoneal laparoscopic pyeloplasty for ureteropelvic junction obstruction in pelvic kidneys in pediatric patients. METHODS A transperitoneal laparoscopic approach was used for performing a pyeloplasty in 4 pati...
This case report describes a distal ureteral atresia along with ureteropelvic junction obstruction which occurred in a 19-month-old female child. It is easily to be misdiagnosed as mere ureteropelvic junction obstruction and omitted the combined diagnosis of distal ureteral atresia. Dismembered pyeloplasty was done in local hospital after admission, however with the result of recurrent fever wh...
PURPOSE To evaluate the results of a sequence of 47 laparoscopic Anderson-Hynes pyeloplasties for the treatment of patients with ureteropelvic junction obstruction, independently of the etiology. MATERIALS AND METHODS Twenty male and 27 female patients diagnosed with ureteropelvic junction obstruction were treated by Anderson-Hynes transperitoneal laparoscopic dismembered pyeloplasty from Apr...
