Preoperative superselective transarterial embolization in laparoscopic partial nephrectomy: technique, oncologic, and functional outcomes.

Introduction: We report the mid-term oncologic and functional results of a series of 110 patients treated with transperitoneal laparoscopic partial nephrectomy (LPN) after superselective arterial embolization (SEA).

Materials And Methods: Between August 2003 and August 2007, 110 patients underwent LPN after SEA for T1 renal tumors. All data were collected in a prospectively maintained database.

Retrograde placement of ureteral stent and ureteropelvic anastomosis with two running sutures in transperitoneal laparoscopic pyeloplasty: tips of success in our learning curve.

Purpose: We report our experience of transperitoneal laparoscopic dismembered pyeloplasties describing our step-by-step surgical technique, and we retrospectively analyze the impact on operative times of technical modifications that were introduced during the learning curve.

Patients And Methods: From November 2002 to May 2008, 84 consecutive patients with ureteropelvic junction (UPJ) obstruction were selected for laparoscopic pyeloplasty (LP). The main steps of the surgical procedure are described.

Superselective embolization as first step of laparoscopic partial nephrectomy.

Objectives: Laparoscopic partial nephrectomy is currently very hard to perform because of the great difficulty in obtaining renal parenchymal hemostasis during tumor excision and the consequent high risk of bleeding. The aim of this study was to propose a method to decrease the risk of bleeding, consisting of the superselective embolization of tumor vessels before performing the laparoscopic partial nephrectomy.

Methods: Fifty patients with small, solitary, enhancing, predominantly exophytic renal tumors underwent a superselective radiographically guided embolization of tumor vessels.
