Birth defects ....  Obstruction of Urinary tract 5
Posted in 2013


Ureterovesical (UVJ) obstruction is much less frequent than is UPJ obstruction, and like UPJ
obstruction, can be unilateral or bilateral.    It is an abnormality in the insertion of the ureter
into the bladder, blocking the flow of the urine into the bladder, and is fixed by surgically
reinserting the ureter into the bladder, the same as is done for vesicoureteral reflux (see
hydronephrosis without obstruction).
A ureterocele is a cystic dilatation of the ureter as it inserts into the bladder.  The cystic
area "pouches" into the bladder and causes the opening for urine flow from the ureter into
the bladder to be very constricted, resulting in obstruction and hydronephrosis.     It can
often be handled at cystoscopy, with excision of the abnormal tissue with a small knife

passed through the cystoscope.  There can be associated dysplasia on the side of the
ureterocele, but not always.
A neurogenic bladder is usually associated with a problem with the spinal cord, the most
common being a myelomeningocele (often referred to by the lay public as spina bifida).
This is a defect where the vertebrae in the lumbosacral area are not properly fused all the
way around the spinal cord, and so a sac protrudes from the spinal cord with a mass of
nerves all tangled together.   In these nerves are those to the bladder, so that it has no
functional nerve supply.  The bladder then tends to fill and fill and only empty by overflow
when it is quite full.  There is often backpressure to the kidneys.  This can lead to
vesicoureteral reflux (explained later in this treatise) and chronic infection and scarring of the

kidneys, with eventual renal failure.


My advise
1..... Follow healthy habits and give birth to Healthy child
