Abstract

Management and decision-making in patients with bilateral renal masses are controversial. To report our experience of surgical management in patients with bilateral renal masses undergoing surgery at a high-volume center. We retrospectively collected data from patients trea- ted with partial nephrectomy (PN) or radical nephrectomy for bilateral renal masses at a single referral institution between June 2008 and June 2019. Patient- and tumor- related features, timing (one vs two stage), and surgical approach (open vs robotic) were analyzed. A one- versus two-stage strategy was adopted according to the opportunity to perform at least one PN using a clampless or selective-clamping approach, in order to avoid acute kidney injury. Operative time, warm ischemia time, and intra- and postoperative com- plications were recorded. Histopathological results and tumor histology were assessed. Overall, 41 patients were included. The median age was 67 yr and the median preoperative estimated glomerular filtration rate (eGFR) was 84 ml/min/1.73 m2. The median Preoperative Aspects and Dimensions Used for an Anatomical (PADUA) score was 8 (interquartile range [IQR] 7–8) for both sides. In 17 (42%) patients, a simultaneous approach was chosen, with a pure robotic approach in 11/17 cases, while among the 24 (58.6%) patients treated with a two-stage strategy, 15 (62.5%) were treated with a robotic approach on both sides. Intraoperative complica- tions and postoperative major (CDC 3) complications were recorded in 7.3% and 4.9% of cases, respectively. The overall positive surgical margins rate was 2.4%. At a median follow-up of 42 (IQR 18–59) mo, the median eGFR was 73 (IQR 64–80) ml/min/1.73 m2, while disease-free survival and cancer-specific mortality were 90.2% and 7.3%, respectively. Our experience underlines that both simultaneous and staged surgical treatment of patients with bilateral renal masses are feasible and safe if grounded on proper patient selection.
