Ureterocystoplasty in bilaterally functional kidneys.

Area of Science:

• Urology
• Pediatric Surgery
• Reconstructive Surgery

Background:

• Traditional augmentation cystoplasty using gastrointestinal segments can lead to metabolic issues and potential carcinogenesis.
• There is a need for alternative bladder augmentation techniques lined by urothelium.

Purpose of the Study:

• To evaluate the clinical and functional outcomes of ureterocystoplasty in children with neurogenic bladder.
• To assess the efficacy and safety of using ureters for bladder augmentation.

Main Methods:

• Ureterocystoplasty was performed on 7 children (ages 1-7) with neurogenic bladder, incontinence, and high-grade reflux.
• Patients underwent pre- and post-operative voiding cystourethrography (VCU) and Technetium-99m DTPA renal scintigraphy.
• Follow-up included assessment of continence, bladder capacity, intravesical pressure, renal function, and voiding patterns.

Main Results:

• Postoperatively, mean intravesical pressure decreased from 45.6 to 18.9 cm H2O, and mean bladder capacity increased to 279.3 ml.
• All patients achieved continence, and VCU confirmed the absence of reflux.
• Renal function showed mild to moderate improvement; 43% could void spontaneously, while 57% required clean intermittent catheterization.

Conclusions:

• Ureterocystoplasty is an effective bladder augmentation method for children with bilaterally functional kidneys.
• The procedure demonstrates an acceptable complication rate and provides stable long-term results.
• This urothelium-lined technique offers a viable alternative to gastrointestinal segments for bladder augmentation.
