World War I was over, and The Jikei University School of Medicine urology Department was established as the first Department of Urology in Japan in February, 1922 (1922) when Washington navy arms limitation treaty Washington Treaty on the Limitation of Naval Armament was linked. It was the next year of the The Jikei University authorization than establishment of Seiikai Kosyujyo which was forerunner of The Jikei University School of Medicine 41 years later.
When Kanehiro Takaki of navy army surgeon opened Seiikai Kosyujyo in 1881 (Meiji 14), The Jikei University School of Medicine begins.

There was not Department of Urology, and the field of urology department was treated with dermatology and a surgical part in those days. Therefore studying abroad in Europe persuaded Bunzo Asakura (figure 1) who was the same period in the same class of President Eigoro Kanasugi The Jikei University, too and received in The first professor.

He wrote "the value of the destruction by fire method of his refuse gone intravesical sphincter region for anischuria" and "cystoscopy" in the clinical achievements. He untied particularly cystoscopic importance, and there was big contribution in making a special ability of this technique universality. He made a phosphorus gray improvement type cystoscope and a mirror of the same type in Japan in the sixth urinary disease congress in 1917, and a demonstration did this, and even this country showed what a cystoscope could make (86 pages of seven Japanese urinary disease society magazines 2).

In 1922, Bunzo Asakura closed Asakura Hospital taking the opportunity of what reached the 60-year-old sixtieth birthday, but we were invited as Professor in February, 1922 by The Jikei University School of Medicine.

  • Figure 17 The Jikei University Kashiwa Hospital (Kashiwa-shi, Chiba):

It is the change of the outpatient department new patient number of patients figure 19 We showed the foreign new patient total number (figure 19) and number of the bladder urethroscopy according to the year of outpatient department section in (figure 20). 2000-3000 a year new patients received our department with each hospital and showed tendency to increase year by year.  We performed bladder urethroscopy with each hospital urology department in outpatient department for these 20 years, and we were alone, and person who received multiple endoscopy carried out around 1,000 a year bladder urethroscopy although we were, and it was almost calculation that endoscopy was done as for one of three of newly ill patient.

It is the change of the number of cystoscope enforcement figure 20 Decrease in urogenital tuberculosis that was specific infectious disease was recognized as each hospital for main urinology infectious disease from about 1985, and after that 1981 through 1986 showed tendency to decrease to sexually transmitted disease (STD) at peak.  It was different, and, as for acute cystitis, the year did not have the increase and decrease with each hospital either, but we received designation in The Jikei University Hospital as identification function Hospital in 1994, and it was that purpose, or, as for this disease, it was one of the diseases that there was few indicating decrease.
We almost showed tendency to increase with each hospital, each malignant tumor for malignant tumor, but increase from the late 1980s when abdominal ultrasonography came to be carried out in generalists as for the kidney malignant tumor positively was remarkable, and prostate cancer increased from the early 1990s when prostate specific antigen(PSA) spread.

It is the change of the hospitalization number of patients figure 21 We show the hospitalization total number (figure 21) according to the year, the operation total number (figure 22) in hospitalization section.
We showed tendency to increase with the number of the hospitalization, the number of the operations at each hospital, and, in approximately 700, each outbuilding, around 300-400 were hospitalized with The Jikei University Hospital a year recently.
But measure shortening for length of stay because we have limit to urology department bed capacity with each hospital; is under the pressure of necessity. As for both tumors, increase was remarkable except testicular tumors for malignant tumor, and it followed that we supported change of recent this country cancer number of patients.
We increased with increase of each disease and were still placed as TUR-P, TUR-BT as main operations of each hospital urology department from the number of the operations even now in TUR which was representative endoscopic operation of the urology department.
As for the Urinary stone treatment, outside the body expression shock wave lithodialysis device (ESWL) is installed in The Jikei University Hospital since 1987 (EDAP LT-02, Dornier Lithotripter D)
We assume ambulatory medical treatment as, principle. The Urinary stone hospitalization number of patients showed tendency to increase including The Jikei University Hospital with each hospital, too. As for the operation for Urinary stone, skill in open cut stone was carried out flourishingly until about 1984, but it took as PNL,TUL afterwards and was taken place, and it became clear that PNL,TUL decreased with adaptation expansion of ESWL more.
We gave an outline in this About us, study, medical treatment situation as things mentioned above.
