Successful Treatment of Renal Cell Carcinoma with Contralateral Humeral Metastasis by Gasless Laparoendoscopic Single-Port Radical Nephrectomy via Retroperitoneal Anterior Subcostal Incision

The positioning and type of incision are important initial steps for successful surgery without complications. We occasionally encounter the Renal Cell Carcinoma (RCC) patients who are suitable for supine positioning rather than flank positioning in Radical Nephrectomy (RN). Thus, we developed an approach via a small Retroperitoneal Anterior Subcostal Incision (RASI) in the supine position for RN by gasless laparoendoscopic single-port surgery (GasLESSRN) which is one of the minimally invasive surgeries. This is the first case report of RCC with contralateral humeral metastasis managed by GasLESSRN via RASI in the supine position and suggests that the approach via a small RASI is an alternative useful approach for GasLESSRN in RCC patients who are considered suitable for supine positioning.
