Decreased linear growth associated with intestinal bladder augmentation in children with bladder exstrophy

Area of Science:

• Pediatric Surgery
• Urology
• Developmental Biology

Background:

• Bladder exstrophy is a congenital condition requiring complex surgical reconstruction.
• Enterocystoplasty is a common surgical technique used to augment bladder capacity and improve continence in patients with bladder exstrophy.

Purpose of the Study:

• To investigate the impact of enterocystoplasty on linear growth in patients with bladder exstrophy.
• To compare growth patterns in patients who underwent intestinal bladder augmentation with those who did not.

Main Methods:

• A case-controlled study was conducted with 50 patients undergoing enterocystoplasty and 50 matched controls with nonaugmented bladder exstrophy.
• Growth charts were analyzed for 17 augmented and 15 nonaugmented patients with at least one pre- and post-operative height measurement.

Main Results:

• 82% of augmented patients (14/17) experienced a significant decrease in percentile height post-surgery (mean loss of 15.6 percentile points).
• Delayed growth occurred in 33% of controls (5/15) after age 7.7 years, but the overall group showed average growth.
• The mean age at surgery was 7.7 years, with follow-up periods of 5.7 and 7.3 years for augmented and control groups, respectively.

Conclusions:

• Intestinal bladder augmentation is strongly associated with a near-universal reduction in percentile height.
• Long-term monitoring and investigation into metabolic changes are crucial for developing strategies to mitigate growth impairment.
