Hydronephrosis without obstruction 3 Posted in 2013 Megaureter and megacystis are two problems that often occur together. Megaureter is the  congenital dilatation of all or a portion of the ureter without obstruction.    Megacystis means  enlargement of the bladder, which may affect function in that the bladder may be slow to empty, and in some cases this may mean that intermittent catheterization is needed to empty the bladder.  Both megaureter and megacystis are frequently associated with renal  dysplasia.

Hydronephrosis without obstruction 2 Posted in 2013 Prune belly syndrome occurs almost exclusively in boys; there is a controversy whether  there is a variant in girls.  It consists of a group of findings including:   decreased or absent  abdominal muscles, cryptorchidism (failure of the testicles to descend into the scrotum; they remain in the abdomen), and dilatation of the ureters and bladder, often with associated  renal dysplasia.  Frequently the dilated ureters come with vesicoureteral reflux (VUR; see  below).    The boys are sterile and unable to make sperm, even if the testicles are surgically brought down, but they function normally sexually.  The bladder may be large and floppy and  not contract and empty like it should, ...

Hydronephrosis without obstruction 1 Posted in 2013 Hydronephrosis without obstruction means dilatation of the ureter and collecting system of the kidney but not because of backup above an area of narrowing and obstruction, rather primary dilatation of the collecting system and ureter.  The conditions causing this that I will discuss are: * Prune belly syndrome * Vesicoureteral reflux * Primary megaureter with or without megacystis My advise 1....

Birth defects .... Obstruction of Urinary tract 5

Birth defects ....  Obstruction of Urinary tract 5 Brought to U.... http://successgain.us     and    http://successgain.info My memories 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 ...

Posterior urethral valves is a fairly common defect, and it occurs because a fold or two of extra tissue grow in the urethra...
