Warm Ischemia Time Articles

BERKELEY, CA (UroToday.com) - Frankly, I was a little surprised by the results of this study. I was expecting to see no difference in the postoperative renal function between the two groups.

SAN DIEGO, CA USA (UroToday.com) - The transition from open to robot-assisted partial nephrectomy (RAPN) has been gaining momentum in recent years, with advances in instrumentation and technology.

One of the most important steps of the partial nephrectomy (PN) is hemostatic control of tumor bed which also effects the warm ischemia time (WIT). Argon beam coagulation (ABC) for decades is a well-known method for surface controls during major open surgical sites.

In the interest of renal functional preservation, partial nephrectomy has supplanted radical nephrectomy as the preferred treatment for T1 renal masses. This procedure usually involves the induction of renal warm ischemia by clamping the hilar vessels prior to tumor excision.

To analyze and compare the intraoperative and post-operative outcomes of "on-clamp" laparoscopic partial nephrectomy (LPN) with "preoperative super-selective angioembolization" before LPN.

To evaluate the outcomes of robotic partial nephrectomy compared with those of laparoscopic partial nephrectomy for T1 renal tumors in Japanese centers.

Patients with a T1 renal tumor who underwent robotic partial nephrectomy were eligible for inclusion in the present study.

Robot-assisted partial nephrectomy (RAPN) outcomes might be importantly affected by increasing surgical experience (EXP). The aim of the study is to investigate the effect of EXP on warm ischemia time (WIT), presence of at least one Clavien-Dindo ≥2 postoperative complication (CD ≥ 2), and positive surgical margins (PSMs) to define the learning curve for RAPN.
