The objective of this paper is to report our initial experience in laparoendoscopic single-site surgery (LESS). One patient underwent LESS varicocelectomy and another patient underwent LESS pyeloplasty. The Triport was inserted into the abdomen through the umbilical incision. In the varicocelectomy, testicular vessels were coagulated by a vessel-sealing system, and transected. In the pyeloplasty, a 2-mm needlescopic port was added to facilitate the procedure, and a dismembered procedure was performed. Total operative duration was 60 min for the varicocelectomy and 240 min for the pyeloplasty. Blood loss was minimal and no perioperative complications occurred. At the 3-month follow up, no postoperative complications were observed and there was no complaint of pain. LESS varicocelectomy and pyeloplasty were successfully performed with excellent cosmetic results and no complications.
