Vesicoureteral reflux (VUR) is the most common underlying etiology responsible for febrile urinary tract infections (UTIs) or pyelonephritis in children. Along with the morbidity of pyelonephritis, long-term sequelae of recurrent renal infections include renal scarring, proteinuria, and hypertension. Treatment is directed toward the prevention of recurrent(More)
PURPOSE The benefits of minimally invasive surgery in pediatric urology, such as reduced length of hospital stay and postoperative pain, are less predictable compared to findings in the adult literature. We evaluated the choices that adult patients make for themselves and their children regarding scar location. MATERIALS AND METHODS We surveyed the(More)
PURPOSE No consensus exists regarding the most effective procedure for neovagina formation. We describe our experience with modified single Monti tube colovaginoplasty in pediatric patients with disorders of sexual differentiation. MATERIALS AND METHODS Six patients were retrospectively identified who underwent primary sigmoid vaginoplasty with a modified(More)
PURPOSE The vesicoureteral reflux index is a novel tool designed to predict spontaneous reflux resolution in infants younger than 2 years. We performed a multi-institutional validation study to confirm the discriminatory power of the vesicoureteral reflux index to predict the vesicoureteral reflux resolution rate in young children. MATERIALS AND METHODS(More)
PURPOSE Molecular characterization of renal cell carcinoma may help differentiate benign oncocytoma from malignant renal cell carcinoma subtypes and predict metastasis. Chemokines, eg IL-8 and chemokine receptors such as CXCR4 and 7, promote inflammation and metastasis. SDF-1 is a CXCR4 and 7 ligand with 6 known isoforms. We evaluated the expression of(More)
In an effort to preserve renal function, nephron-sparing approaches such as partial nephrectomy are now routinely performed for the treatment of small renal masses (SRMs). To date, several groups have studied the utility of examining the renal parenchyma contained beyond the tumor margin of partial nephrectomy specimens for histopathologic evidence of(More)
BACKGROUND Molecular profiling of renal cell carcinomas (RCCs) may improve the distinction between oncocytoma and malignant RCC subtypes and aid in early detection of metastasis. The hyaluronic acid (HA) family includes HA synthases (HAS1, HAS2, HAS3), hyaluronidases (HYAL-1, HYAL-2, HYAL-3, HYAL-4, PH20, HYAL-P1), and HA receptors (CD44s, CD44v, RHAMM). HA(More)
Renal cell carcinoma (RCC) is largely diagnosed incidentally on imaging taken for unrelated reasons. The management of localized lesions is primarily extirpative with excellent results. Treatment of advanced RCC has evolved over recent years with the use of targeted therapies such as tyrosine kinase inhibitors, mammalian target of rapamycin inhibitors, and(More)
Renal cell carcinoma with tumor thrombus of the inferior vena cava presents a special surgical challenge. The use of surgical techniques derived from the field of transplantation surgery have previously been shown to enable optimal control of inferior vena cava, allowing for the extirpation of most tumors via a transabdominal approach without the need for(More)
PURPOSE Despite ongoing advances in the field of endourology, there are few reports describing specific changes adopted by urologists that have come as a result. We investigated the progression of single surgeon's clinical practice over a 12-year period, noting differences in ureteroscopes, ancillary equipment, and indications for surgery over that time.
