Urethral diverticulum: Complication of abdominoperineal pull-through procedure

Diverticulum of the Male Urethra with a Giant Stone and Multiple Calculi

“…Other predisposing factors of urethral stone formation are a ureteral or bladder calculus that is lodged in the urethra, calcification around a foreign body or hair (scro tal flap plasty), urethral stenosis and trauma [8], In the present case, urethral trauma due to long-standing ure thral catheter drainage and use of a Cunningham penis clamp thereafter, associated with chronic infection, are the causes to consider for diverticulum and diverticular calculi formation. When present, diverticular calculi are solitary [9] (in contrast to our case) and may attain con siderable size without causing severe symptoms.…”

Posterior urethral diverticula: a complication of surgery for high anorectal malformations

“…Within the above definition, the pouches that we have described are not true diverticula, since their walls have colonic mucosa with an underlying functional muscular coat. Indeed, in all the five other cases described in the literature, the histological examination of the excised diverticula showed colonictype mucosa [9][10][11]. This finding is not surprising, since the pouches actually represent the remains of the original rectourethral connection.…”

“…The onset of recurrent urinary tract infections, as in four of our five cases, or the development of enuresis or dribbling incontinence in a previously dry child (present in three of the five) are strongly suggestive of the diagnosis. Indeed, this has been the mode of presentation in all the cases described in the literature [9][10][11]. The exact symptomatology depends to some extent on the location and size of the diverticulum and fistulous track.…”
