Surgical practices for urological tumors: A nation‐wide survey in Japan in 2005

Abstract

Objective: To clarify how popularly the minimally invasive surgeries for urological tumors are currently conducted in Japan and to predict future trends. Methods: A nation-wide survey was performed by the Japanese Association for Minimum-Incision Endoscopic Surgery under the support of the Japanese Urological Association (JUA). A questionnaire was sent to 1186 JUA-certified educational institutions asking about surgical practices for representative urological tumors performed in 2005 and those to be performed in the near future. Surgical modalities were categorized into open, laparoscopic and minimized-incision surgeries, defined as that the operator considers the incision to be minimal and including minimumincision endoscopic surgery but not limited. Results: 506 of the 1186 institutions (43%) responded and 20 193 surgical procedures were reported with radical prostatectomy being most frequently performed. Overall 20% and 6% of the procedures were performed with laparoscopic and minimized-incision surgeries, respectively. More than 20% of the respondents performed open surgery with reduced incision size than before. Surgical procedures without inserting fingers or hand were reported in 5-11% of the open surgeries and 33-45% of the minimized-incision surgeries. Endoscopy was utilized in 4-14% of the open surgeries and 24-59% of the minimized-incision surgeries. There was no difference in the incidence of complications among the surgical modalities. 40% and 27% of the respondents are aiming at laparoscopic surgery and at minimized-incision surgery, respectively. Conclusions:The results of this nation-wide survey indicate that minimally invasive surgeries, currently performed in 26% of urological tumor surgeries, are aimed at by the majority of the survey respondents.

Simple prophylactic procedure of inguinal hernia after radical retropubic prostatectomy: Isolation of the spermatic cord

“…A robust increase of prostate cancer in Japan has rendered the radical retropubic prostatectomy (RRP) the most frequently performed major tumor surgery in the urological field 1,2 . Urinary incontinence and erectile dysfunction are the two major complications after RRP, and extensive efforts have been devoted to overcome them 3 .…”

Characteristics and management of erectile dysfunction after various treatments for prostate cancer

“…The use of this procedure continues to increase in many countries worldwide. In a nation‐wide survey performed by the Japanese Association for Minimum‐Incision Endoscopic Surgery with the support of the Japanese Urological Association, 13% of the institutions that responded to the survey were performing minimally invasive surgery, and more than half of them were aiming at introduction of the surgery in the near future 6 . The goal of minimally invasive surgery such as LRP is to achieve a lower perioperative complication rate, earlier postoperative recovery, good oncological results, and better functional outcome including preservation of potency and earlier recovery of urinary continence.…”

Gasless single‐port access endoscopic surgery in urology: Minimum incision endoscopic surgery, MIES

“…With societal acceptance, certification as advanced surgery, and coverage by the Japanese universal health insurance system, MIES is now performed in most prefectures in Japan and the number of hospitals offering this operation has increased steadily. At the same time, minimization of the incision in open surgery, deemed to be the preparatory stage in MIES, is also becoming prevalent across Japan 52 . A formal MIES society, ‘The Japanese Society of Minimum Incision Endoscopic Urological Surgery’, was established in 2008 22 .…”
