Stomach versus sigmoid colon in children undergoing major reconstruction of the lower urinary tract

Area of Science:

• Urology
• Surgical Innovation
• Reconstructive Surgery

Background:

• Bladder augmentation is crucial for conditions like neurogenic bladder and bladder exstrophy.
• Intestinocystoplasty (ICP) and gastrocystoplasty (GCP) are established techniques for bladder reconstruction.
• Long-term outcomes and specific complications require continued evaluation.

Purpose of the Study:

• To review the clinical and metabolic outcomes of 50 patients undergoing ICP or GCP.
• To compare the efficacy and complications of ICP versus GCP.
• To assess the overall success rate and identify factors influencing outcomes.

Main Methods:

• Retrospective review of 50 patients undergoing augmentation cystoplasty or total bladder replacement over 8 years.
• Analysis of clinical data, metabolic parameters, and surgical complications.
• Categorization of diagnoses including neurogenic bladder and bladder exstrophy.

Main Results:

• Overall success rate of 79.15% for both ICP and GCP.
• Mild hyperchloremic acidosis noted in 36% after sigmoid augmentation (ICP).
• Dysuria-hematuria syndrome (DHS) observed in 50% of GCP patients; no operative mortality.

Conclusions:

• ICP effectively increases lower urinary tract compliance but poses risks of stones, mucus, and electrolyte imbalance.
• GCP minimizes electrolyte absorption, making it suitable for patients with renal compromise and potentially enabling normal voiding in some cases.
• Patients should be informed about the potential for DHS, which warrants further investigation.
