    Abstract:
    PURPOSE: We present the long-term results of simultaneous "teapot" ureterocystoplasty and ureteral Mitrofanoff in patients with bilateral megaureters due to neurogenic bladder, and compare urodynamic results before and after the procedure. MATERIALS AND METHODS: We treated 13 children (mean age 7.3 years) with end stage neurogenic bladder and refluxing megaureters (mean diameter 5.5 cm) with simultaneous teapot ureterocystoplasty and Mitrofanoff appendicovesicostomy between April 1995 and May 2001. The larger ureter was used for teapot bladder augmentation while keeping its distal 2 cm tubularized. The Mitrofanoff channel was then created using the opposite ureter. RESULTS: Followup ranged from 109 to 169 months (median 121). At the end of the followup period all patients were dry with clean intermittent catheterization and/or voiding. No repeat augmentation was needed and there were no bladder calculi during followup. Median postoperative bladder capacity was 430 ml (IQR 380 to 477), which was increased significantly compared to preoperative evaluations (210 ml, IQR 181 to 230, p = 0.001). During followup bladder compliance also improved significantly (p = 0.001) and serum creatinine level decreased (p = 0.021). CONCLUSIONS: Although neurogenic bladder and high grade reflux are poor prognostic factors for ureterocystoplasty, the present modification resulted in enduring bladder augmentation with no calculus formation. Bladders remained compliant with good capacity, presumably because sufficient tissue and blood supply were provided for the augmented flap.
