BACKGROUND AND PURPOSE: Several disposable platforms have been introduced for laparoendoscopic single-site (LESS) surgery. Besides technical issues, cost is one of the main limiting factors for their widespread use. We present our experience with LESS surgery for kidney pathologies using the first completely reusable LESS platform. PATIENTS AND METHODS: We performed LESS kidney procedures in 29 patients including nephrectomy (18), partial nephrectomy (3), pyeloplasty (4), and renal cyst ablation (4). All procedures were performed using a completely reusable single-port device (X-Cone) with a simplified combination of standard and prebent instruments. We obtained perioperative and demographic data including a visual analog pain scale (VAS); complications were recorded using Clavien grading. RESULTS: Mean patient age was 49.31 years. Conversion to standard laparoscopy was necessary in one and addition of a needlescopic instrument in four cases. No open conversion was necessary. Intra- and postoperative complications occurred in two (Clavien II) cases. Mean operative time was 110, 90, and 89 minutes, and hospital stay was 4.9, 3.1, and 3.6 days for nephrectomy, partial nephrectomy, and pyeloplasty, respectively. Mean VAS was 2.13, 1.67, and 1.5 while blood loss was 81.3 mL, 140 mL, and 17.5 mL, respectively. There were no positive resection margins. CONCLUSIONS: LESS with a completely reusable platform is feasible for different upper urinary tract procedures yielding favorable functional and cosmetic results. A simplified combination of standard straight instruments and a single prebent grasper facilitates handling and shortens the learning curve. Reusable materials significantly reduce cost and may help to further adopt LESS surgery in surgical practice.
