RESUMO

ABSTRACT Objective There is limited data regarding surgeon volume and partial nephrectomy outcomes. The aim of this study is to report trifecta outcomes of robot-assisted partial nephrectomy (RAPN) performed by the low volume surgeon. Materials and Methods Thirty-nine patients with clinical T1-2 renal tumors who underwent RAPN between 2012 and 2018 were included in this study. Trifecta was defined as negative surgical margins, warm ischemia time ≤20 minutes, and no operative complications. Patient demographics, R.E.N.A.L. nephrometry score, operation time, estimated blood loss, warm ischemia time, length of hospital stay, renal functions, and oncological outcomes were analyzed retrospectively. Complications were graded based on the modified Clavien-Dindo classification system. Results The median R.E.N.A.L. nephrometry score was 6 (4-10). RAPN was successfully performed in all but one patient. The median operation time was 180 (90-240) minutes. Warm ischemia was performed only by segmental renal artery control in 35 and, by main renal artery control in three patients. The off-clamp technique was used in two patients. The median warm ischemia time was 16 (0-31) minutes. Seven patients had a warm ischemia time of longer than 20 minutes. Three patients had postoperative complications. The surgical margin was positive in one patient. As a result, the trifecta was achieved in 30 of the 39 patients (77%). Conclusion RAPN is a safe and effective minimally invasive alternative in the treatment of renal masses. The present study suggests that reasonable trifecta rates can be achieved even by low volume surgeons.

RESUMO

ABSTRACT Introduction Cancer is one of the most important leading cause of death in man and woman in the world. The occurrence of new cancer has become more frequent in recent years due to strict screening protocols and occupational and environmental exposure to carcinogens. The incidence of secondary malignancies has also increased due to close medical follow-up and advanced age. Herein, we report a case and its management diagnosed as synchronous peritoneal malignant mesothelioma and muscle-invasive urothelial carcinoma. Case Description A 71-year-old male presented with macroscopic hematuria and abdominal distension increasing gradually. A contrast enhanced computerized tomography demonstrated bladder mass and diffuse ascites with nodular peritoneal thickening and umbilical mass. He was treated with the multidisciplinary team working including urologist, medical oncologist and general surgeon. Conclusions To our knowledge, this is the first case of peritoneal malign mesothelioma with synchronous muscle-invasive urothelial carcinoma. Because of the rarity of this condition, there is still no consensus on the definitive treatment protocols, yet. Individualized treatment with multidisciplinary close follow-up might improve the survival outcomes.
