Flow matters 2: How to improve irrigation flow in small-calibre percutaneous procedures-the purging effect.

Introduction: Aim of this study was to investigate whether the combination of high-pressure irrigation inflow combined with simultaneous sensor-controlled suction could improve irrigation turnover without leading to high peak intrarenal pressure in small-calibre percutaneous instruments (SCPI). M + M: A MIP XS sheath (9.5 Fr.

Laparoendoscopic partial nephrectomy in single-incision triangulated umbilical surgery (SITUS) technique: early experience.

Background: Nephron sparing surgery for renal tumors has evolved as the standard of care for resectable renal tumors. Laparoscopic partial nephrectomy (PN) has gained recognition after technical refinements were able to match the well-established criteria for open partial nephrectomy. Laparoendoscopic surgery (LESS) is one of the approaches to further minimize invasiveness of laparoscopic surgery.

New ex vivo organ model for percutaneous renal surgery using a laparoendoscopic training box: the sandwich model.

Purpose: Percutaneous renal surgery (PRS) is a challenging procedure for urologic surgeons and requires a large variety of different skills. Our objective was to improve the preexisting porcine kidney-training model for percutaneous renal access and PRS.

Methods: For our biologic training model, we use porcine kidneys with preserved ureter.

Minimally invasive percutaneous nephrolithotomy: an alternative to retrograde intrarenal surgery and shockwave lithotripsy.

Purpose: There is a lack of studies comparing shock wave lithotripsy (SWL), retrograde intrarenal surgery (RIRS) and minimally invasive percutaneous nephrolithotomy (MIP) in renal stone treatment. This study compared treatment outcome, stone-free rate (SFR) and stone-free survival (SFS) with regard to stone size and localization.

Methods: This analysis included 482 first-time-treated patients in the period 2001-2007.

Laparoscopic radical cystectomy: initial experience using the single-incision triangulated umbilical surgery (SITUS) technique.

Introduction: As could be demonstrated for simple and radical nephrectomy, single-incision triangulated umbilical surgery (SITUS) is an interesting alternative to laparoscopic single-site surgery. We present our initial experience with the SITUS technique in radical cystectomy.

Materials And Methods: Between September 2010 and September 2011, eight patients underwent SITUS radical cystectomy (SITUS Cx), pelvic lymph node dissection and extracorporeal urinary diversion.
