N2 - Objective: To prospectively compare outcomes of laparoendoscopic single-site and multiport laparoscopic radical nephrectomy and partial nephrectomy, focusing on postoperative pain and analgesic requirement. Methods: Nonrandomized, prospective comparison of laparoendoscopic single-site and multiport laparoscopic radical nephrectomy and partial nephrectomy. Thirty-four patients underwent laparoendoscopic single-site (17 radical nephrectomy/17 partial nephrectomy); 42 underwent multiport laparoscopy (28 radical nephrectomy/14 partial nephrectomy) from February 2009 to February 2010. Laparoendoscopic single-site transperitoneal access was obtained by periumbilical incision through which all trocars were inserted. Laparoendoscopic radical nephrectomy/partial nephrectomy recapitulated steps of multiport laparoscopic radical nephrectomy/partial nephrectomy. Demographics/tumor characteristics, outcomes, and complications were analyzed. Results: Forty-two of 42 multiport laparoscopic and 32/34 laparoendoscopic single-site cases were successfully performed. Mean follow-up was 16.2 months. For laparoendoscopic single-site and multiport laparoscopy groups mean operating room time (min) was 159.3 vs 158.9 (P =.952); mean estimated blood loss (mL) was 175.7 vs 156.1 (P =.553); percent transfused was 2.9% vs 0% (P =.925). No significant differences in complications were noted (P =.745). Significant decrease in analgesic use (6 morphine equivalents vs 11.6, P <.001) and discharge pain score (1.7 vs 2.7, P <.01) were noted in laparoendoscopic single-site vs multiport laparoscopic radical nephrectomy. For laparoendoscopic single-site partial nephrectomy and multiport laparoscopic partial nephrectomy, no significant differences were noted for tumor diameter (1.8 vs 2.0 cm, P =.57), RENAL score (0.962), ischemia time (28.6 vs 27.5 minutes, P =.70), and preoperative (P =.78)/postoperative creatinine (P =.32). For laparoendoscopic single-site radical nephrectomy and multiport laparoscopic radical nephrectomy, no significant differences were noted for mean tumor diameter (5.6 vs 5.3 cm, P =.63), RENAL score (P =.815), and mean operative time (142.3 vs 155.4 minutes P =.13). Conclusion: In this well-matched, prospective comparison, laparoendoscopic single-site is comparable with multiport laparoscopic surgery in terms of perioperative parameters and may confer benefit with respect to analgesic requirement. Randomized evaluation and longer-term follow-up are necessary.
