[The urodynamics of the lower urinary tract after reconstructive operations in bladder exstrophy].

The results of plastics of the bladder with local tissues in its exstrophy in 34 children were appraised according to the findings of clinical, functional, and morphological studies. The cosmetic effect was satisfactory in 22 patients, but control over urination remained unsuccessful as a rule. Enuresis after sphincteroplasty was linked with functional insufficiency of the trigonal muscle due to tissue dysembryogenesis. Another component of enuresis was dysfunction of the bladder attended by intravesical hypertension and uninhibited contractions when its size was small. The results of morphological studies allowed the authors to explain the character of the urodynamic disorders and the inefficacy of their nonoperative correction.
