反復性尿路感染症における男子重複尿道の1例

Abstract

A dorsal incomplete duplicated urethra was found in a 13-year-old male, who had noticed occasional urinary incontinence and recurrent urinary tract infection. The accessory urethra lay dorsal from the glans to bladder neck in parallel with the normal ventral urethra. The external orifice of the accessory urethra was also dorsal to the normal urethral orifice in the glans. Voiding cystourethrogram demonstrated double stream but the patient did not notice it because of pseudophimosis. Retrograde urethrogram showed the accessory urethra which arised from the dorsal surface of the prostatic urethra with a parallel normal urethra. The pendular portion of the accessory urethra was surgically removed, the glans portion of the urethra and posterior urethra were cautilized with electrocoagulation for the purpose of preservation of urinary continence. The patient was postoperatively free from urinary tract infection and urinary incontinence.
