Selective versus nonselective arterial clamping during laparoscopic partial nephrectomy: impact upon renal function in the setting of a solitary kidney in a porcine model.

Introduction: Laparoscopic partial nephrectomy has emerged as a standard of care for small renal masses. Nevertheless, there remains concern over the potential for irreversible insult to the kidney as a result of exposure to warm ischemia. We aim to investigate the utility of selective segmental arterial clamping as a means to reduce the potential for ischemic damage to a solitary kidney during laparoscopic partial nephrectomy utilizing a porcine model.

Open versus laparoscopic retroperitoneal lymph node dissection: assessing adequacy of dissection in a porcine model.

Background And Purpose: Laparoscopic retroperitoneal lymph node dissection (L-RPLND) is emerging as a viable alternative to traditional open retroperitoneal lymph node dissection (O-RPLND). Despite numerous reports confirming clinical oncologic equivalency between the two approaches, however, concerns still remain over the adequacy of laparoscopic dissection. We therefore sought to compare the completeness of dissection between O-RPLND and L-RPLND in a porcine model.

Comparison of laparoscopic and percutaneous cryoablation of renal tumors: a cost analysis.

Cryoablation of renal masses is an evolving in situ ablative technique for the management of localized renal masses and can be performed in a laparoscopic or percutaneous manner. Its usefulness is increasing and correlates with the increasing frequency of incidentally diagnosed renal lesions. At present, this technique has been applied to patients deemed to be poor surgical candidates for extirpative therapy or those with a strong desire to avoid surgery, at least until long-term data become available to fully evaluate its cancer-control effectiveness.

Laparoscopic urological surgery: a review.

In this manuscript some of the more common laparoscopic procedures and their indications will be reviewed.

Renal-artery pseudoaneurysm after laparoscopic partial nephrectomy.

Background And Purpose: Laparoscopic partial nephrectomy (LPN) has emerged as a minimally invasive treatment for small renal masses. The most common complications include hemorrhage and urinary-fistula formulation. Renal-artery pseudoaneurysm has been described after open nephron-sparing surgery.

Vesicoureteral reflux: diagnosis and management.

Vesicoureteral reflux is the retrograde passage of urine from the bladder into the ureter and kidneys during voiding. This commonly-treated entity is frequently managed by different disciplines that include Urology, Nephrology and Pediatrics. The pathophysiology of vesicoureteral reflux seems to be related to the valve mechanism of the ureterovesical junction.
