Abstract
OBJECTIVES: To evaluate the current status of urological laparoendoscopic single-site and reduced port surgery in Japan. METHODS: Of the 152 institutions to which councilors of the Japanese Society of Endourology belong, 42 (28%) have carried out laparoendoscopic single-site and reduced port surgery. A total of 32 of these institutions agreed to participate in this survey. Patients who had undergone surgery between January 2008 and March 2014 were included in the present study. RESULTS: Overall, 1145 cases of laparoendoscopic single-site and reduced port surgery were recorded during the study period. The most frequent procedures were adrenalectomy and radical nephrectomy. Laparoendoscopic single-site and reduced port surgery represented 12% (872/7311) of all laparoscopic procedures carried out at participating institutions. The number of patients who underwent pyeloplasty, donor nephrectomy and simple nephrectomy tended to increase, whereas those who underwent adrenalectomy, radical nephrectomy and nephroureterectomy peaked in 2012, and then tended to decrease in 2013. The rates of conversion, perioperative and postoperative complications, were 2.7%, 2.2% and 4.5%, respectively. CONCLUSIONS: The number of laparoendoscopic single-site and reduced port urological surgeries in Japan has increased for benign indications, such as pyeloplasty, donor nephrectomy and simple nephrectomy. In contrast, procedures such as adrenalectomy and radical nephrectomy are trending down after reaching a peak in 2012. Overall, laparoendoscopic single-site and reduced port urological surgery in Japan is being safely carried out when compared with other reported series of laparoendoscopic single-site surgery and conventional laparoscopic surgery.
