INTRODUCTION Appendicovesicostomy (APV) and Monti ileovesicostomy (Monti) are commonly used catheterizable channels with similar outcomes on short-term follow-up. Their relative long-term results have not been previously published. OBJECTIVE Our goal was to assess long-term durability of APV and Monti channels in a large patient cohort. STUDY DESIGN In(More)
PURPOSE Occult tethered cord syndrome applies to patients with signs and symptoms consistent with a caudal spinal cord malformation despite normal neuroimaging. Although several reports of successful surgical treatment exist, controversy remains with respect to patient selection and efficacy. We present a large series with excellent clinical followup,(More)
PURPOSE We report the long-term outcome of the Malone antegrade continence enema procedure in the treatment of chronic constipation and fecal incontinence in children with neuropathic bowel. MATERIALS AND METHODS We performed a retrospective chart review of 256 Malone antegrade continence enema procedures. Patient age at surgery, bowel segment used,(More)
Obstruction of the upper urinary tract induces a progressive loss in renal mass through apoptotic renal cell death. Although TNF-alpha has been implicated in ischemia-reperfusion-induced apoptotic renal cell death, its role in obstructive renal cell apoptosis remains unknown. To study this, male Sprague-Dawley rats were subjected to left unilateral ureteral(More)
INTRODUCTION The treatment of urogenital sinus malformations is complex and controversial. Despite numerous and significant contemporary surgical advances, the dissection of the urogenital sinus remains technically challenging. METHODS Based on total urogenital mobilization, we describe a technique whereby this dissection is limited to the pubourethral(More)
The past several decades have seen multiple advances in the surgical reconstruction for girls born with Disorders of Sexual Differentiation. This surgery can be technically very demanding, and must be individualized for each patient, as the degree of virilization and level of confluence of the vagina and urogenital sinus will dictate the surgical(More)
PURPOSE Bladder augmentation has revolutionized the care of children with a neuropathic bladder but it remains a major surgical procedure. However, the need for subsequent bladder surgery has not been well defined in a large series with long-term followup. MATERIALS AND METHODS We retrospectively reviewed the records of the first 500 bladder augmentations(More)
Neurofibromatosis is a hamartomatous disorder of neural crest derivation characterized by cutaneous pigmentation and tumor formation in various tissues. Visceral involvement is typically insidious, progressive, and difficult to treat. Plexiform neurofibroma of the urinary tract is rare. Involvement of nearly every genitourinary structure by these lesions(More)
PURPOSE Vitamin B12 deficiency is a feared complication of enterocystoplasty but it has never been demonstrated in pediatric patients who have undergone ileal enterocystoplasty. We reviewed our series of more than 500 bladder augmentations in an attempt to define the timing and risk of vitamin B12 deficiency in pediatric patients after bladder augmentation.(More)
An isolated segment of stomach was used for bladder augmentation in 10 patients or construction of a continent urinary reservoir in 3. Diagnosis in these 13 patients included cloacal exstrophy (5), myelodysplasia (4), posterior urethral valves (2), radiation cystitis (1) and neurogenic bladder secondary to a rectal pull-through procedure (1).
