[Vesicostomy in children].
OBJECTIVE
To evaluate the upper urinary tract morphology and function in children undergoing vesicostomy for different causes.


METHODS
We report on 27 children aged 1 month to 12 years who had undergone a Blocksom vesicostomy procedure. Twenty had a neuropathic bladder and 3 had posterior urethral valves.


RESULTS
In the 20 children with neuropathic bladder, renal function improved in 95% and the associated vesicoureteral reflux improved in 56%. The morphology of the upper urinary tract returned to normal prior to the definitive operation in all cases. Only one of the patients with posterior urethral valves has preserved satisfactory renal function two years following vesicostomy. The most common complication was prolapse (14.8%).


CONCLUSIONS
In our view, vesicostomy is the best urinary diversion procedure in the cases described herein. Vesicostomy closure must be performed following definitive treatment of the underlying condition, except in those cases with neuropathic bladder who require augmentation cystoplasty to keep upper urinary tract pressures low.
