OBJECTIVE Urethral-enteric fistulae with hypoplastic/atretic distal urethra in boys with anorectal malformations are amenable to management via sequential dilation of the distal urethra (P.A.D.U.A.) and subsequent repair of the fistula, but failure of this technique occasionally requires complex reconstruction. We present a novel surgical approach, along(More)
Pathologic staging in colorectal adenocarcinoma (CA) is based on the concept that the timing of metastatic tumor spread is directly related to the depth of the primary tumor invasion. To evaluate the temporal sequence of CA metastasis, we performed microdissection mutational profiling at multiple microscopic sites of primary and metastatic CA specimens.(More)
PURPOSE In the setting of signs and symptoms of testicular torsion the absence of diastolic flow and/or color flow on Doppler ultrasound has traditionally prompted emergent scrotal exploration. This practice emanates largely from the difficulty on ultrasound of distinguishing salvageable torsed testes from those that are not salvageable. We identified(More)
PURPOSE We evaluated the usefulness and interobserver concordance of a novel grading system for dynamic ureteral hydrodistention. MATERIALS AND METHODS Between May 1, 2002 and July 1, 2008 the hydrodistention grade in 697 ureters was prospectively assigned and recorded, including H0-no hydrodistention, H1-ureteral orifice open but tunnel not evident,(More)
PURPOSE Management of neonatal torsion is controversial, since the likelihood of testicular salvage and metachronous contralateral torsion must be weighed against the risk of neonatal anesthesia. We reviewed a large series of such cases and stratified neonatal torsion based on time of presentation to determine the potential for testicular salvage. To our(More)
OBJECTIVE Criteria for success following endoscopic vesicoureteral reflux (VUR) surgery vary greatly. We sought to define outcomes based on radiographic and long-term clinical follow up. METHODS We reviewed the charts and interviewed parents of children who underwent endoscopic treatment for primary VUR (grades I-IV). All patients had a postoperative(More)
PURPOSE Biofeedback is known to effect symptomatic and objective cure in children with dysfunctional voiding. While some authors advocate animation assisted biofeedback to achieve success, we previously demonstrated similar success without animation. We recently used animated biofeedback aimed at simplifying muscle isolation and encouraging patient(More)
The aim of this article is to assess the treatment efficacy of percutaneous endopyelotomy and laparoscopic pyeloplasty to establish a new algorithm in the minimally invasive treatment of ureteropelvic junction obstruction (UPJO). Hospital records, office charts, and radiographic studies of patients with UPJO treated either endoscopically (n = 50),(More)
BACKGROUND AND PURPOSE Minimally invasive office-based treatments for benign prostatic hyperplasia (BPH) are challenging the traditional surgical and medical management options for symptomatic BPH. We conducted a meta-analysis of published randomized controlled trials that compared high-energy transurethral microwave thermotherapy (HE-TUMT) with(More)
