Off-clamp renal tumourectomy by retroperitoneoscopy in posterior renal tumors of medium complexity (Padua score 8–9)

摘要: Abstract Background The guidelines recommend partial surgery for T1 renal tumors. Various aspects of this have evolved in recent years, including the clamping method and duration, enucleation, retroperitoneoscopic approach use 3 mm ports. We present our initial series on laparoscopic tumourectomy by retroperitoneoscopy (LRTR) analyse learning curve 3-mm instrumentation. Material methods From January 2011 to 2015, we performed LRTR 50 patients with posterior or convex After 10 cases, technique changed off-clamp, 11 cases were subsequently Results mean tumor size was 34.36 mm (14–62), a PADUA score 8.42 (5–12). operative time 163.1 min (75–300), warm ischemia 4.21 min (0–28). main artery not clamped 41 (82%) patients, no vessel (zero ischemia) 39 (78%) patients. Seven had positive margins (6 focal). Eleven LRTRs instrumentation, shorter surgical times, less intraoperative bleeding hospital stays. Conclusions Retroperitoneoscopy coupled enucleation enables extirpation without tumors, relatively short curve. material be performed, although experience it has resulted higher rate margins.
