“…Naito et al showed the effectiveness of the microwave tissue coagulator for reducing blood loss when nephron-sparing surgery is performed without arterial occlusion. 7 This procedure was expected to prevent ischemic damage induced by vascular clamping. If so, residual renal function would be lower after conventional PNx compared to that after non-clamping PNx.…”

Background : Partial nephrectomy (PNx) has been performed with temporary renal arterial occlusion and in situ renal hypothermia (conventional PNx). However, the impact of temporary renal arterial occlusion on residual renal function has not been well assessed. To address this question, we performed renal scintigraphy with 99m technetium-dimercaptosuccinic acid (DMSA) for the quantitative measurement of postoperative residual renal function after conventional PNx and partial nephrectomy without arterial occlusion (non-clamping PNx). Methods : Thirty-four patients underwent postoperative DMSA scintigraphy after PNx for renal cell carcinoma. No obvious difference in preoperative renal function between the diseased kidney and the contralateral kidney was found in any of the patients. Of these patients, 24 underwent conventional PNx, and 10 underwent non-clamping PNx. Residual renal function was evaluated using the relative DMSA uptake of the operated kidney.Results : The relative DMSA uptake of the operated kidney was 39.9 ± 7.3% (25.1-58.8) after conventional PNx compared to 34.8 ± 8.9% (13.5-45.5) after non-clamping PNx. This difference was not statistically significant ( P = 0.15). Total ischemic time during conventional PNx had no adverse influence on the residual renal function. In the analysis of the other determinant factors influencing residual renal function, tumor size was the only significant factor that inversely correlated with the relative DMSA uptake. Conclusion : Our results showed that arterial clamping during PNx has no negative impact on the functional residual capacity as long as in situ renal hypothermia is adequately performed.

“…Although a major problem associated with traditional LPN is the control of bleeding from the resected site, hemostasis has been safely obtained by various procedures such as tumor resection after radiofrequency ablation [8] or microwave tissue coagulation [9,10] around a tumor, ultrasound dissection [11], hydro-jet dissection [11], and usage of argon beam coagulation [12] or a holmium:YAG laser [12] after tumor resection.…”

“…The microwave tissue coagulator, which was introduced by Tabuse [13], is useful for controlling parenchymal bleeding in solid vascular organs. Kagebayashi et al [9] and Naito et al [10] reported that this apparatus was also useful in PN, and some reports have described its effectiveness during LPN [14]. Microwaves cause thermal coagulation in renal tissues around the electrode, and a bloodless area is obtained through the vascular constriction caused by this thermal effect.…”

Transumbilical laparoendoscopic single-site partial nephrectomy using a microwave tissue coagulator

et al. 2012

Transumbilical single-port laparoscopy has emerged as a method to further enhance cosmetic benefits and reduce morbidity. We present an initial experience with transumbilical laparoendoscopic single-site partial nephrectomy (LESS-PN). A 36-year-old woman visited our hospital for the treatment of a left exophytic renal cell carcinoma, 17 mm in diameter, located at the lower pole. We decided to use transumbilical LESS-PN to treat this case. A multichannel port was placed through the center of the umbilicus, and the tumor was exposed using bent laparoscopic instruments. The tumor was then removed after microwave tissue coagulation. All procedures were performed without renal artery occlusion, and only slight bleeding occurred. Transumbilical LESS-PN using a microwave tissue coagulator was performed with an excellent cosmetic outcome and no complications. To the best of our knowledge, this is the first report of LESS-PN using a microwave tissue coagulator.

“…The technique remains largely experimental although some early clinical experience has been described [50,51]. The technique has also been described as an adjunct to open partial nephrectomy in order to provide a bloodless plane before resection [52].…”
