Salvage robotic transmesenteric off-clamp partial nephrectomy after multiple prior open kidney surgeries. [PDF]

Urol Case Rep, 2020
Repeat renal surgery is technically demanding with a high morbidity rate. We describe a novel surgical approach, a salvage robotic transmesenteric off-clamp partial nephrectomy for the management of a renal cell carcinoma in a patient with a history of ...

Cholinergic feedback to bipolar cells contributes to motion detection in the mouse retina

Cell Reports, 2021
Summary: Retinal bipolar cells are second-order neurons that transmit basic features of the visual scene to postsynaptic partners. However, their contribution to motion detection has not been fully appreciated.

Safety of on- vs off-clamp robotic partial nephrectomy: per-protocol analysis from the data of the CLOCK randomized trial [PDF]

, 2019
Purpose To compare the safety of on- vs off-clamp robotic partial nephrectomy (RAPN). Methods 302 patients with RENAL masses <= 10 were randomized to undergo on-clamp (150) vs off-clamp (152) RAPN (CLOCK trial-ClinicalTrials.gov NCT02287987) at seven ...

Off-Clamp Robot-Assisted Partial Nephrectomy for Complex Renal Tumors

Journal of Endourology, 2012
Considering the potential impact of warm ischemia time (WIT) on renal functional outcomes after robot-assisted partial nephrectomy (RAPN), many techniques that reduce or eliminate WIT have been studied. We present our institutional experience and progression using one such technique-off-clamp RAPN-as well as the results of this technique in the ...

Off-Clamp Robot-Assisted Partial Nephrectomy: Initial Washington University Experience

Journal of Endourology, 2012
Because of the impact warm ischemia time may have on renal function, various surgical techniques have been proposed to minimize or eliminate warm ischemia. The purpose of this study is to evaluate our initial renal functional outcomes of off-clamp robot-assisted partial nephrectomy (RAPN), while assessing the safety profile of this unconventional ...
