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 ...

background & importance: infections of the craniocervical junction are rare. case presentation: we present a case of infection by methicillin-sensitive staphylococcus aureus and streptococcus mitis that was not previously reported. conclusion: neurosurgeons must suspect for diagnosis and initiate broad antimicrobial therapy, including active agents against gram-negative and then initiate a targ...

background: field matching problems in abutting electron fields can be managed by using spoilers. objective: the aim of this study was to design a monte carlo framework for the assessment of spoiler application in abutting electron fields. methods: a siemens primus treatment head was simulated for a 5 mev electron beam using beamnrc and dosxyznrc, egsnrc user codes. validation of beam model was...

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...

background: this study aimed to investigate the pedicle dimension and angulation in cervicothoracic junction (ctj) using the findings of computed tomographic (ct) to help accurate insertion of pedicular screw. methods: forty three patients with high quality ct images of ctj were evaluated. pedicle width (pw), pedicle height (ph), pedicle axis length (pal), transverse angle (ta) and sagittal ang...

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...
