Another 75 patients of the entire 907 subjects who were tracked had other conditions (ureterocele: eight cases; stones: seven cases; cystic dysplasia: 43 cases; megaureter
: 15 cases; and Wilms' tumor: two cases) that did not progress to CKD.
Congenital anomalies of the kidney and urinary tract (CAKUT) comprise a spectrum of malformations that occur at the level of the kidney (e.g., hypoplasia and dysplasia), collecting system (e.g., idiopathic hydronephrosis, ureteropelvic junction obstruction, and megaureter
), bladder (e.g., ureterocele and vesicoureteral reflux), or urethra (e.g., posterior urethral valves) .
an obstructive megaureter
in three patients and ectopic obstructive ureterocele in two patients.
Se encontraron otras condiciones anatomico funcionales asociadas al RVU tales como: anillo uretral (5/41), post trasplante renal (5/41), doble sistema colector (2/41), vejiga neurogenica (2/41), megaureter
(2/41), valvas de uretra posterior (1/41) y ureterocele (1/41).
is defined as dilated ureter with or without dilatation of the renal pelvis and calyces.
Se han descrito anomalias genitourinarias en el 20% de los casos reportados como agenesia o displasia renal y megaureter
, entre otras.
Ureteral and urethral abnormalities Ureteropelvic junction obstruction Ureteral duplication/bifid ureter Vesicoureteral reflux Primary megaureter
Ureteral ectopia Posterior urethral valves In combination with A, B, or C III.
In children, ultrasound is useful as a screening examination to evaluate for hydro nephrosis, megaureter
, and renal ectopia.
