Abstract

Objective: To report on a multi-institutional series of non-robotic urological laparoendoscopic single-site surgery in Japan. Methods: Consecutive cases of laparoendoscopic single-site surgery carried out between February 2009 and December 2012 at nine academic institutions were included. We examined the surgical outcomes, including conversion and complications rates. Results: Four hundred and sixty-nine cases were included in the analysis. The most common procedure was adrenalectomy (n = 177) and the second most common procedure was radical nephrectomy (n = 143). The procedures also included nephroureterectomy (n = 40), living donor nephrectomy (n = 40), pyeloplasty (n = 30), urachal remnant excision (n = 9), simple nephrectomy (n = 7), radical prostatectomy (n = 6) and others (n = 17). The access sites included umbilicus (n = 248, 53%) and other sites (n = 221, 47%). A transperitoneal approach was used in 385 cases (82%), and retroperitoneal approach in 84 cases (18%). The median operation time of all procedures was 198 min. Conversion to reduced port surgery, conventional laparoscopy, or open surgery was noted in 27 cases (5.8%), 12 cases (2.6%), and two cases (0.4%), respectively, with an overall conversion rate of 8.7%. Intraoperative complications occurred in 10 cases (2.1%). Post-operative complications were noted in 29 cases (6.2%), including five major complications (1.1%). No mortality was recorded in this series. Conclusions: Non-robotic laparoendoscopic single-site surgery is technically feasible and safe for various urologic diseases in Japan. Furthermore, urological laparoendoscopic single-site surgery is a promising minimally invasive surgical option that is feasible for experienced urological surgeons in intermediate-volume centers as well as high-volume centers.
