3,5] Patients with ureteral duplication may potentially have urinary stones, ureterocele
, vesicoureteral reflux (VUR) and obstructive uropathy.
Neither ultrasound nor MRI studies were able to demonstrate hydroureter or ureterocele
The right ureterocele
was excised and Cohen type ureteroneocystostomy was performed.
We consider that patients with high risk for ureteral injury are those with a large median lobe, a ureter orifice that is atypically close to the bladder neck, a large ureterocele
, a severe ureteral kink, and a history of pelvic radiotherapy or transurethral resection of the prostate.
1) In ultrasound imaging, irregular and edematous walls and adequate openings of the ureterocele
can be detected by radiologists.
Suggested terminology for duplex systems, ectopic ureters and ureteroceles

Other authors have questioned the clinical significance of hydronephrosis and suggest resorting to VCUG when the patient has ultrasound findings consistent with renal dysplasia or hypoplasia, renal cystic disease, cortical thinning, loss of corticomedullary differentiation, high-grade unilateral or bilateral dilation, alteration in the kidney number or kidney size, presence of ureteroceles
or hydroureteronephrosis, or suspected bladder outlet obstruction (such as thickening of the bladder wall or ureters) (1,6.
The etiology of hydroureteronephrosis was neurogenic bladder secondary to meningomyelocele in five patients, a posterior urethral valve (PUV) in four patients, an obstructive megaureter in three patients and ectopic obstructive ureterocele
in two patients.
De los pacientes tratados con RVU grado II, 8 casos (80%) presentaron UCGM normales, mientras que los 2 casos restantes (el 20%) disminuyeron su grado de reflujo a I, estando relacionados a un ureterocele
destechado y a una disfuncion del vaciamiento vesical respectivamente.
intravesical em caes normalmente e assintomatica e, apesar de poucos diagnosticos, sao causas importantes de obstrucao (1,2,4,5).
Thirty three urograms showed normal outline of the urinary system while, 94 were abnormal due to calculi, cystocele, ureterocele
, pelvi ureteric junction obstruction, pelvic mass and perinephric abscess.
