Bladder neck obstruction caused by a large simple ureterocele in a young male

Abstract

The most common clinical presentation of ureterocele is infection of the urinary tract. Much less common is obstruction of the bladder outlet by prolapse of the ureterocele into the urethra. Even less common is simple occlusion of the bladder outlet by a nonprolapsing ureterocele. We present such a case where a large, simple ureterocele in a young male led to such obstruction.

Ureterocele prolapse eliciting unusual patient behavior to control intermittent voiding

“…Although ureterocele prolapse is frequently due to an ectopic ureterocele, 3 our patient presented with prolapse of a simple ureterocele. VCUG findings showed that the ureterocele was not sufficiently large to be pushed by the wall of the bladder dome and had migrated to the bladder neck, causing bladder outlet obstruction.…”

“…1 The most common manifestations of ureteroceles are urinary tract infections, and rarely, bladder outlet obstruction by a ureterocele prolapse occurs. 2 , 3 Moreover, ureteroceles that present with sudden cessation of the urinary stream while voiding in childhood are exceedingly rare. 3 …”

Anomalies of the Distal Ureter, Bladder, and Urethra in Children: Embryologic, Radiologic, and Pathologic Features

“…The defect leading to this anomaly is thought to be a persistent Chwalla membrane with consequent obstruction at the fusion point between the mesonephric duct and urogenital channel (34). It can often be followed into a dilated ureter deep within the bony pelvis and can occasionally obstruct the bladder (36). A simple ureterocele may be demonstrated at US, VCUG, or IVU (35).…”
