Abstract:
Objective This study is to explore the safety,feasibility and efficacy of robotic laparoendoscopic single-site(LESS) zero-ischemia partial nephrectomy.Methods Two patients underwent robotic laparoendoscopic single-site zero-ischemia partial nephrectomy by our urologic surgical team at 22-May-2017 and 31-May-2017 in our institution.The salient patient demographics and tumor characteristics,including age,gender,body mass index (kg/m2),Charlson Co-morbidity Index (Age-weighted),tumor laterality,diameter (cm),R.E.N.A.L.nephrometry score and preoperative split renal function GFR [ml/(min · 1.73 m2)] were:73/56,female/male,25.2/19.8,2/0,lcft/right,1.8/1.4,5a/4a,left 43.8、right 49.2/left 38.8 、right 48.7 respectively.A 2-3 cm longitudinal skin incision was made at 4 cm below the inferior margin of rib arch at the level of midaxillary line (case NO.1) or peri-umbilicus (case NO.2).The da Vinci Si robotic Single-siteTM Port was inserted.The line of Toldt was incised with the colon medially mobilized.Gerota's fascia was opened,the main renal artery or its branches were dissected,then the renal mass fully dissected and exposed.The renal mass was entirely removed with approximately 0.5-1.0 cm surrounding normal renal parenchyma (unclamping in case NO.1,and selective branch clamping in case NO.2) and kidney reconstruction was conducted with 1-0 Quill Suture via hem-o-lock sliding technique.Results The two procedures were smoothly completed without any extra skin incision.Operative duration,estimated blood loss and skin incision length was respectively 230/190 min,100/60 ml,3.6/2.5 cm.Duration of two selective renal artery branches clamping in case NO.2 was 39 and 24 min.Postoperative pain measured by the visual analog pain scale (VASP) at day 1,day 2,day 3 was 5/4,3/3,2/1,Time off oral intake,duration of drainage and length of stay after surgery was 2/4 d、2/4 d、6/7d,respectively.The recovery of both patients were uncomplicated and discharged smoothly.Pathological examination revealed oncocytoma in case NO.1 and papillary renal cell carcinoma in case NO.2.Conclusions The initial experience shows the robotic laparoendoscopic single-site zero-ischemia partial nephrectomy is a safe,feasible and efficacious procedure.It may exhibit clinical benefits for patients in terms of pain control,convalescence and cosmesis,but in this early stage the clinical indications should be strictly controlled.
