Robot-assisted intracorporeal ileal conduit: Marionette technique and initial experience at Roswell Park Cancer Institute.

Objectives: To present our technique and initial experience with patients who underwent robot-assisted intracorporeal creation of ileal conduit and to compare them with patients who underwent extracorporeal ileal diversion after robot-assisted radical cystectomy.

Methods: Twenty-six patients diagnosed with invasive transitional cell carcinoma of the bladder underwent a robot-assisted radical cystectomy with bilateral extended pelvic lymphadenectomy with ileal conduit diversion. Total intracorporeal ileal conduit creation was performed in the last 13 patients.

Percutaneous biopsy of renal cell carcinoma underestimates nuclear grade.

Objectives: To assess the accuracy of renal biopsy for predicting the final nuclear grade and histologic subtype. Small renal masses can be safely observed in select patients who are poor surgical candidates. Renal biopsy may help identify patients who are candidates for observation.
