[Augmentation ureterocystoplasty in children: 7-years follow-up].

OBJECTIVES

We retrospectively reviewed our experience of augmentation ureterocystoplasty in children to evaluate its long-term results.

MATERIALS AND METHODS

From February 1996 to March 1999 four children (2 boys and 2 girls) with neurogenic bladder had augmentation cystoplasty using dilated ureter in our institute. After trans-uretero-ureterostomy the lower two thirds of the unilateral ureter was used to perform the augmentation cystoplasty. Follow-up varied between 59 and 96 months (mean 85).

RESULTS

In early post-operative period bladder volume and compliance increased from 96 (64-150) to 113 (40-220) ml and from 2.7 (1.3-5.8) to 4.5 (2.0-11.0) ml/H2O respectively. Incontinence was improved in all children and two had dry interval of 3-hour catheterization. Although bladder volume and compliance kept increasing gradually (239 (237-241) ml, 11.5 (5.7-18.5) ml/H2O respectively) over 5 years postoperatively, 2 elder patients had repeat augmentation cystoplasty using gastrointestinal tract because of hydronephrosis and deterioration of renal function.

CONCLUSION

Our long-term result of ureterocystoplasty was no good. Ureter is not an ideal material to provide adequate bladder capacity and compliance for elder children unless their bladder becomes as large as that of adults early post-operatively.
