However cheap 200mg cardarone amex, micturating cystourethrography and scinti- graphy are considered the gold standard investigations for reflux and scarring, respectively. Age Symptoms 1 month Failure to thrive to 2 years Feeding problems Diarrhoea Unexplained fever UTI in this age group can also masquerade as gastrointestinal colic. Vesicoureteric reflux Abnormal retrograde flow of urine from the bladder into the ureter and renal collecting system is termed vesicoureteric reflux. Reflux may occur as a result of a congenital abnormality at the vesicoureteric junction or may be associated with a neurogenic bladder or a partial bladder outlet obstruction. Reflux is significant because it predisposes the whole of the urinary tract to ascending infection. Chronic or recurrent inflammation of the kidney (pyelonephritis) can lead to renal cortical scarring with increased risk of hypertension and renal failure in later life. Hydronephrosis Hydronephrosis is the dilation of the renal pelvi-caliceal collecting system pro- ximal to an obstructing lesion (Fig. A pelvi-ureteric junction obstruction is the common- est cause of hydronephrosis and may result from intrinsic stenosis, functional obstruction or compression of the pelvi-ureteric junction by an aberrant artery or fibrous band. Unilateral or bilateral hydronephrosis can be seen in the presence of a urete- rocele at the vesicoureteric junction and will also be associated with dilatation of the ureter(s). Simple renal dilatation can occur without obstruction in condi- tions such as vesicoureteric reflux and in such cases may be a transient phenomenon. Posterior urethral valves Posterior urethral valves are the commonest cause of lower urinary tract obstruc- tion in boys and result from mucosal folds that obstruct the urethra and cause bladder outlet obstruction. The diagnosis is often made prenatally with ultra- sound showing a dilated fetal urinary system and reduced amniotic fluid volume. Posterior urethral valves may be detected in the postnatal period fol- lowing clinical examination of a healthy neonate with a distended bladder and poor urinary stream. Occasionally the condition presents with overflow inconti- nence or urinary tract infection in later childhood. Micturating cystourethrogra- phy in these cases will demonstrate bilateral obstructive hydronephrosis which may also be associated with vesicoureteric reflux7.

The same applies to large more conservative approach is appropriate here than for osteochondromas of the proximal humerus, which can the lower extremities. On the forearm osteochondromas the risk of deformation is much less than for the leg. In the upper extremity, neither lesion usually re- on this classification, the corresponding treatment shown quires treatment. In young patients we use Osteochondromas of the distal radius and ulna should the clavicles as a replacement for the proximal humerus. The ulna can be lengthened via an acromioclavicular joint and fixed to the residual fragment intramedullary Prévot nail, which prevents bowing of the of distal humerus[8] (⊡ Fig. Enchondromas on the hand can occasionally prove troublesome if they cause the bone to expand. Removal by curettage is indicated in such cases, and the defect can be filled with a cancellous bone graft.

Since the subtalar joint a runs at an oblique angle to the horizontal best 200 mg cardarone, the joint is not clearly visualized on the lateral view. In particular, the coalition cannot be seen on a conventional x-ray when the connection is fibrous or purely cartilaginous. A much clearer picture is obtained with an oblique x-ray of the rearfoot, in which the beam is inclined at 45° to the hori- zontal. Views in various oblique positions are sometimes needed to visualize a bone connection clearly since the overlaying of bone structures can be mistaken for a bridge b formation (⊡ Fig. An MRI scan shows a characteristic, of polydactyly are also observed in Ellis-van-Creveld hyperintense subchondral zone, even if the coalition is syndrome. Classification Treatment The treatment of symptomatic tarsal coalition is surgical.
