Vidit Sharma, Tanner S Miest, Tristan S Juvet, Amir Toussi, Vignesh Packiam, Karim Chamie, Surena F Matin, Stephen A Boorjian, R Houston Thompson, Igor Frank, Matthew K Tollefson, Aaron M Potretzke,

<h4>Introduction</h4>Diagnostic ureteroscopic biopsy for upper tract urothelial carcinoma (UTUC) has been hypothesized to increase intravesical recurrence of urothelial carcinoma after radical nephroureterectomy (RNU). Moreover, the impact of ureteroscopy without biopsy or percutaneous biopsy on intravesical recurrence remains unknown. Herein, we compared post-RNU intravesical recurrences across UTUC diagnostic modalities.<h4>Methods</h4>Patients undergoing RNU ... Read more >>

Percutaneous resection of metastatic renal cell carcinoma.

Amir Toussi, Deepak Agarwal, Bradley Leibovich, Aaron Potretzke,

<h4>Introduction</h4>Metastasis-directed therapy of small solitary foci of metastatic renal cell carcinoma has been associated with improved survival. Percutaneous resection of tumors in the upper tract urinary system has been widely used for treatment of localized urothelial carcinoma, however, its role in renal cell carcinoma has not been described. Herein, we ... Read more >>

Small Renal Masses in Close Proximity to the Collecting System and Renal Sinus Are Enriched for Malignancy and High Fuhrman Grade and Should Be Considered for Early Intervention.

Andres F Correa, Amir Toussi, Milon Amin, Ronald L Hrebinko, Bishoy A Gayed, Anil V Parwani, Jodi K Maranchie,

INTRODUCTION:Recent reports show a correlation between renal tumor radiographic characteristics and pathologic features. We hypothesize that a more central location within the relatively hypoxic renal medulla might confer a more aggressive tumor phenotype. To test this, radiographic tumor characteristics were compared with tumor grade and histology. MATERIALS AND METHODS:We retrospectively ... Read more >>
