Urological Outcome of the Xiao Procedure in Children with Myelomeningocele and Lipomyelomeningocele Undergoing Spinal Cord Detethering.

Purpose: Although previous studies have revealed high success rates (70% to 85%) after an intradural somatic-to-autonomic nerve transfer procedure in children with spinal dysraphism, no study has had a control group or blinded observers. We report a rigorously designed study to investigate the effectiveness of the Xiao procedure.

Materials And Methods: Children with neurogenic bladder dysfunction related to myelomeningocele or lipomyelomeningocele who required spinal cord detethering were randomized to 2 groups at surgery, with half undergoing only spinal cord detethering and half undergoing the Xiao procedure in addition to detethering.

Lack of efficacy of an intradural somatic-to-autonomic nerve anastomosis (Xiao procedure) for bladder control in children with myelomeningocele and lipomyelomeningocele: results of a prospective, randomized, double-blind study.

OBJECTIVE Xiao et al. and other investigators have studied an intradural somatic-to-autonomic (e.g.

Attempted bladder reinnervation and creation of a scratch reflex for bladder emptying through a somatic-to-autonomic intradural anastomosis.

An intradural somatic-to-autonomic anastomosis, or Xiao procedure, has been described to create a "skin-CNS-bladder" reflex that improves bladder and bowel function in patients with neurogenic bladder and bowel dysfunction. The authors present their experience with a 10-year-old boy with chronic neurogenic bladder and bowel dysfunction related to spinal cord injury who underwent the Xiao procedure. After undergoing a left L-5 ventral root to left S2-3 intradural anastomosis, the patient reported that his bladder and bowel dysfunction improved between 6 and 12 months.

Computerized tomography findings in pediatric renal trauma--indications for early intervention?

Purpose: We sought to determine if initial computerized tomography findings in pediatric patients suffering blunt renal trauma with urinary extravasation were predictive of the need for operative intervention.

Materials And Methods: A total of 17 patients with grade IV blunt renal trauma and urinary extravasation were identified between 2000 and 2007. Each computerized tomogram was reviewed to determine location, size and number of sites of extravasation, as well as the presence of contrast material in the ipsilateral ureter.

Is ureteroscopy first line treatment for pediatric stone disease?

Purpose: We report our current outcomes for ureteroscopic management of pediatric stone disease.

Materials And Methods: We carried out a retrospective review of all ureteroscopic procedures for kidney or ureteral calculi performed between 2001 and 2005. Stone location and size, preoperative and postoperative stenting, intraoperative dilation, use of ureteral access sheath, stone-free rates and complications were noted.

Metastatic intratesticular alveolar rhabdomyosarcoma discovered after induction of systemic chemotherapy.

Alveolar rhabdomyosarcoma is an aggressive cancer that can metastasize to a variety of organs. We present what we believe to be the first reported case of metastatic intratesticular rhabdomyosarcoma in a patient presenting with testicular pain shortly after the induction of systemic chemotherapy. The published data regarding this unusual condition are reviewed.

Primary malignant mesothelioma of the penis: case report and review of the literature.

We present an unusual case of primary malignant mesothelioma of the penis in an adult male. The clinical features and microscopic, immunohistochemical, and ultrastructural characteristics that help to identify this entity are described. A discussion of the behavior of malignant mesothelioma follows, as well as a possible explanation for its origin in the penis.
