CHRONIC BLADDER OUTLET OBSTRUCTION: REVIEW OF THE RADIOLOGIC FINDINGS IN A 5 YEAR OLD MALE CHILD: A CASE REPORT
Bladder outlet obstruction (BOO) is a blockage that occurs at the base of the bladder causing an impairment to the normal flow of urine. It is regarded as the common cause of lower urinary tract symptoms in both sexes. The incidence of BOO is different and has a variation in both age and gender, although with a male preponderance.
This is a case of a five-year-old male child referred for micturating cystourethrography (MCUG) and retrograde cystourethrography (RUCG) on account of difficult micturition since birth. The RUCG failed following failure of passage of the smallest size catheter raising a suspicion of urethral stenosis. The MCUG however showed a contrast filled urinary bladder with thickened and irregular shaped walls that showed multiple contrast filled outpouches with a contrast filled column between the outpouches and urinary bladder; diverticula having a spoke-wheel appearance. No contrast is demonstrated within the urethra following attempts at micturition. Bilateral grade I vesicoureteric reflux were also demonstrated. Complimentary abdominopelvic ultrasonography showed bilateral moderate to severe hydroureteronephrosis with a thick-walled urinary bladder. Normal abdominal situs was demonstrated. A diagnosis of chronic bladder outlet obstruction following severe urethral stenosis was made.
We report the radiologic features of chronic bladder outlet obstruction following severe urethral stenosis.
