[Functional reconstruction of urinary bladder exstrophy: long-term follow-up of urinary continence].
The author followed up a group of seven patients 5 to 29 years after functional reconstruction without augmentation on account of classical exstrophy of the urinary bladder. The plastic operation to ensure continence was performed in 5 boys and 2 girls at the age of two and a half to 23 months, in six cases by the Young-Dees' method and in one patient by Leadbetter's method. Posterior iliac osteotomy was performed in two and an antireflux plastic operation was performed in four patients. In one patient a disruption of the plastic operation of the abdominal wall occurred on the fourth day after reconstruction. Continence was excellent in five patients and satisfactory in two. Among the many factors for urinary continence a plastic operation of the posterior urethra and neck of the bladder is most important as it creates the appropriate length of the continence zone and the adequate pressure on closure. In the discussion the author emphasizes the advantage to start with the reconstruction of the abdominal wall and bladder during the neonatal period and to proceed in stages. The functional closure of the bladder and its neck with the posterior urethra should be implemented after a minimal capacity of 60 ml has been attained. Augmentation enterocystoplasty is indicated on account of urinary incontinence as a secondary operation if the function of the urethra and neck of the bladder is satisfactory and achieved capacity is less than 100 ml.(ABSTRACT TRUNCATED AT 250 WORDS)
