Abstract:
Objective To evaluate the long-term functional results, complications and patient's satisfaction level in patients performed augmented enterocystoplasty and continent urinary diversion using the appendix. Methods From 1999 to 2005, there were 22 children (12 males and 10 females) underwent augmented enterocystoplasty and continent urinary diversion using the appendix. Surgical results were reviewed retrospectively. There were 11 eases with bladder and urethra dysfunction attributed to neurogenic bladder, 2 cases with complex genitourinary malformation associated with an imperforated anus, 2 cases with exstrophy-epispadias complex, 2 cases with posterior urethral valves, 3 cases with failed urethrovaginal fistula repair and 2 epispadias cases with post failure of Young-Dees- Leadbetter bladder neck reconstruction. Upper urinary tract dilatation and hydroureteronephrosis were found in 17 eases (28 units), including grade Ⅱ-Ⅴ vesicoureteral reflux in 15 children (24 units). Simultaneous procedures included ureteral reimplantation in 15 cases and bladder neck closure in 14 cases. The appendix was used as the catheterizable conduit placed in the right lower abdomen and clean intermittent catheterization was performed in all patients. Outcomes were assessed by urodynamic study, IVU, ultrasound, voiding cystourethrography, BUN, Cr and electrolyte test. Results Mean follow-up was 3.6 years, ranging from 1.5-6 years. Complications included stomal stenosis requiring dilatation in 2 cases and leakage in 2 cases without bladder neck closure and 1 case required surgical revision. All patients achieved excellent stomal continence. No metabolic acidosis and bladder stone was noted. Upper urinary tract impairment had not worsened in all patients. Conclusion Augmented enterocystoplasty and continent urinary diversion using the appendix are associated with high continence, compliance and satisfaction rate and a low complication rate in the treatment of pediatric patients with disorders related to bladder and urethral dysfunction.
