Comparison of running and interrupted vesicourethral anastomoses in a porcine model.

Purpose: To compare running and interrupted suturing techniques for porcine vesicourethral anastomosis with regard to procedure time, histopathologic effects, and leakage.

Materials And Methods: Twelve domestic pigs were randomized to a running (N = 6) or an interrupted (N = 6) vesicourethral anastomosis with polyglycolic acid sutures. In each case, the bladder was drained for 7 days.

Enhanced renal cryoablation with hilar clamping and intrarenal cooling in a porcine model.

Objectives: To evaluate the effects of renal vascular control and intrarenal cooling on the size of renal lesions attainable with a 3.4-mm cryoprobe.

Methods: Three groups of pigs underwent unilateral laparoscopic renal cryoablation with a 3.

Renal hypothermia achieved by retrograde endoscopic cold saline perfusion: technique and initial clinical application.

We describe the technique and initial clinical results with application of a novel method to achieve renal parenchymal hypothermia using retrograde ureteral access. A 38-year-old man was scheduled to undergo an open right partial nephrectomy for renal cell carcinoma. Before the open procedure, a ureteral access sheath was advanced to the ureteropelvic junction under fluoroscopic guidance; through the access sheath, a 7.
