Patient Care

Urological malignant tumor

Prostate cancer

We perform cystoprostatectomy and radiotherapy for the patients in early stage as radical treatments.
We started to perform robot-assisted cystoprostatectomy in 2013. Erectile dysfunction and urinary incontinence are major complications and aftereffects of cystoprostatectomy. We proactively perform nerve-sparing surgery based on the cancer condition to keep erectile function and improve urinary incontinence early.
Lymph node dissection may be required with prostatectomy to treat locally advanced cancer.
As for radiotherapy, we cooperate with the radiology department to perform radiotherapy at lower risk of side effect such as Intensity Modulated Radiation Therapy (IMRT). We try to provide treatments in enough consideration of patients’ needs.
As medications for advanced prostate cancer with metastasis, we provide wide range of treatments including hormone therapy, chemotherapy, and treatments based on the result of a genetic test.

Renal cell cancer

We proactively perform partial nephrectomy for renal cell cancer smaller than 7 cm in diameter.
We perform robot-assisted surgery for partial nephrectomy. For a large tumor, we perform laparoscopic surgery or laparotomy to resect it.
In some case with renal cancer, tumor progresses to inside of the inferior vena cava. For such cases, we perform tumorectomy in cooperation with hepatic surgeons and vascular surgeons.
We also provide pharmacotherapy for the cases with metastasis.
There are molecular targeted drug, immune checkpoint inhibitor, etc. as medication for renal cancer. These medicines have risks which cause severe adverse events.
We have a system to deal with adverse events relevant to immunity in cooperation with internal medicine physicians.

Urothelial cancer

We perform transurethral resection of bladder tumor (TURBT) for superficial urinary bladder cancer, and administer medication to suppress recurrences based on the pathological result.
We perform total cystectomy for invasive bladder cancer. In order to decrease the chance of recurrence after surgery, we provide the patients with chemotherapy before surgery.
Urinary diversion is required for total cystectomy, so that we basically create an ileal conduit diversion or a urinary reservoir.
For ureteral cancer and renal pelvic cancer, we make diagnoses of them using fiberscope and perform laparoscopic total nephroureterectomy.
For advanced cancer with metastasis, we perform pharmacotherapy including chemotherapy and immune checkpoint inhibitor, etc.

Other malignant tumors

We treat other malignant tumors in the field of urology (testicle cancer, penis cancer, etc.) with surgery or pharmacotherapy.

Robot-assisted surgery, laparoscopic surgery

We perform proactively robot-assisted surgery and laparoscopic surgery for minimal invasion and functional preservation.
We introduced “Da Vinci System” in 2013 and perform about 100 cases of robot-assisted surgery a year.

We perform the following robot-assisted surgery

Robot-Assisted Radical Prostatectomy (RARP) for prostate cancer
Robot-Assisted Partial nephrectomy (RAPN) for renal cell cancer
Robot-Assisted Radical Cystectomy (RARC) for urinary bladder cancer
Robot Assisted Pyeloplasty (RAPP) for pyeloureteral junction stenosis

We perform the following laparoscopic surgery

Laparoscopic nephrectomy
Laparoscopic total nephroureterectomy
Laparoscopic adrenalectomy

Urinary lithiasis

Based on the location and size of the calculi, we decide therapeutic methods.
We proactively try to remove calculi as early as possible by endoscopic surgery intended to not only crush the stones but also remove stone fragments.
We have various therapeutic options such as Extracorporeal Shock Wave Lithotripsy (ESWL), Transurethral Ureterolithotripsy (TUL, f-TUL), Percutaneous Nephrolithotripsy (PNL), etc. We also perform Endoscopic Combined Intrarenal Surgery (ECIRS) which is a method combines TUL with PNL.

Prostatic Hyperplasia

We perform Transurethral Resection of Prostate (TURP), Holmium Laser Nucleation of the Prostate (HoLEP) as surgical treatments for prostate enlargement.


We proactively perform surgery for urethral stenosis.
We have had good outcomes of surgery for urethral stenosis with grafting oral mucous membrane for intractable cases.

Phallocampsis, Peyronie disease

In cooperation with our Reproduction Center, we perform a lot of surgery for phallocampsis and peyronie disease.

Other diseases

In the field of andorology, we cover male sexual dysfunction and male menopause, which has recently become a popular topic. We treat the cases with male sexual dysfunction in need of special treatments or male infertility in cooperation with our Reproduction Center. Besides, we treat particular pediatric diseases in need of surgical treatments in cooperation with the department of pediatric surgery.
