Objective: We evaluated reconstructive and oncological laparoendoscopic single-site surgery (LESS) combined with mini-laparoscopic instruments as standard equipment. Patients and Methods: 30 patients underwent reconstructive and oncological LESS: mini-laparoscopic-assisted LESS pyeloplasty (LESS-P, n = 18), mini-laparoscopic-assisted LESS partial nephrectomy (LESS-PN, n = 7) or mini-laparoscopic-assisted LESS radical prostatectomy (LESS-RP, n = 5). Perioperative data were prospectively collected. Results: The 18 LESS-P cases had operative times ranging between 120 and 180 min (average 147.9 min). Estimated blood loss ranged between 100 and 300 ml (average 202.1 ml). Two patients required additional management for failed reconstruction. LESS-PN was performed in 7 patients with tumor size ranging between 2.5 and 3.8 cm (average 2.7 cm). Average operative time and blood loss were 155 (140-180) min and 321.4 (250-550) ml, respectively. Renal artery clamping took place in 1 case. LESS-RP was performed in 5 patients; average operative time was 156 (140-180) min and average blood loss 196 (100-400) ml. Functional and oncological outcome was directly comparable to laparoscopic radical prostatectomy. Conclusion: The combination of LESS and mini-laparoscopic instrumentation as routine equipment of reconstructive LESS reveals a different perspective for ‘scarless' urologic surgery.
