Patient 4: In the prenatal 27th week, bilateral multicystic kidney,
megaureter and patent urachus were detected.
It may be due to.1 Transient hydronephrosis, pelviureteric junction obstruction, vesicoureteric reflux,
megaureter, multicystic dysplastic kidneys.
The differential diagnosis of ANH, in order of likelihood, includes transient primary hydronephrosis, uretero-pelvic junction obstruction (UPJO), vesicoureteric reflux (VUR), uretero-vesical junction obstruction (UVJO) or primary non-obstructive
megaureter, ureterocele, ectopic ureter and causes of megacystis.
Keating, "Vesicoureteral reflux and
megaureter," in Campbell's Urology, P.
Megaureter quadruplicado associado a duplicacao ureteral contralateral: relato de caso.
He had bilateral hydronephrosis with
megaureter and grade V vesicoureteral reflux to the left and grade I to the right kidney.
In most cases, the renal pelvis and ureters are not dilated, although primary
megaureter can occur with megacalyces [14, 15].
The abnormal findings diagnosed in 15 (18.1%) patients included: mild to severe hydronephrosis in all cases, one
megaureter and one case suspected of nephrolithiasis.
All patients had been diagnosed as primary VUR or primary obstructive
megaureter and undergone cross-trigonal intravesical reimplantation before receiving TBM.
Magnetic resonance (MR) urogram confirmed the presence of narrowing at the ureterovesical junction consistent with primary obstructive
megaureter. Procedure Left intravesical/extravesical ureteral reimplantation with a transverse lower abdomen incision.
