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.

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 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)
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)
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)
The mainstay of treatment for renal cell carcinoma with invasion of the inferior vena cava (IVC) is complete surgical extirpation. Cases complicated by adherent or invasive tumor thrombus represent a special technical challenge due to the need for resection of a large segment of the IVC. The aim of this review is to describe the indications and surgical(More)
OMNEX (Ethicon, Inc.; Somerville, NJ) is a cyanoacrylate-based synthetic surgical sealant. To date, the use of OMNEX has only been described in a limited number of vascular surgery procedures. We present the cases of two patients who underwent successful extracorporeal renal artery aneurysm repair with the aid of OMNEX sealant. This report is the first(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)
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)
OBJECTIVE To describe a modified open surgical technique for the resection of renal cell carcinoma with level I or II tumor thrombus. METHOD In our modified technique, the renal artery is ligated early and the tumor thrombus is secured ahead of kidney mobilization by either milking into the renal vein or with extirpation from the inferior vena cava. We(More)
