Results:Among the28cases,there were7cases of ureteral valve,6cases of duplication of ureter and pelvis,3cases of ureterocele,2cases of diverticula of bladder,2cases of malrotation of kidney,2cases of megaureter,2case of supernumerary kidney,1case of pelvic diverticulum,1cases of ectopic ureter,1case of renal column hypertrophy and1case of pneumogastric vascular near by the ureter.
Results Among these 65 cases,29 were diagnosed as hydronephrosis,3 with salitary renal cyst,10 with multicystic dysplastic kidney,7 with polycystic kidney,5 with renal agenesis,3 with renal deficit,2 with renal enlargement,4 with ureterocele,1 with large bladder,1 with bladder exstrophy and 14 accompanied with other systemic abnormalites.
According to the sonographic patterns of size, shape, periodical change,1 case hydronephrosis, surgical and pathological results, 32 adult ureter cysts were divided into four types: type Ⅰ, papillary(12);
Ectopic ureterocele is a malformation, principally encountered in infants and children.
In all cases the ultrasound studies outlined the ectopic ureterocele within the fluid-filled bladder and in one case added additional information regarding the non-functional portion of the duplication and its ureter.
The diagnosis of "ectopic ureterocele" is based on indirect evidence.
A huge ureterocele may have a small ureter, and massive reflux into a lower pole ureter may make the diagnosis of duplication difficult.
Ureterocele "lookalikes", and effacement or intussusception of the ureterocele are cystographic pitfalls.
