Introduction

The role of Nagoya University Hospital is clinical practice, research and education. The important role in the clinical medicine is development and practice of advanced medical technology and treatment, and creation of scientific evidence. In the research activity, our important mission is to conduct clinical studies to develop an advanced medical technology and provide useful scientific evidence, and to perform basic investigation, especially translational researches, the outcome of which leads to an innovation of clinical medicine. The department of Urology, Nagoya University Graduate School of Medicine practices a wide range of clinical medicine in the field of Urology and also conducting a basic investigation focusing on translational researches.
In our clinical practice, we perform (1) urological endoscopic surgery (laparoscopic surgery for urothelial cancer in the renal pelvis, ureter and bladder, prostate cancer, adrenal tumors; laparoscopic retroperitoneal lymph node dissection; endoscopic surgery for benign prostatic hyperplasia and urinary tract stones), (2) renal transplantation, (3) medical treatment for malignant tumors in the urinary tract (medical treatment of renal cell carcinoma with molecularly-targeted therapy and immune checkpoint inhibitor, chemotherapy or radiotherapy for urothelial cancer and testicular cancer, hormonal treatment/brachytherapy /IMRT/chemotherapy for prostate cancer), (4) robot-assisted surgery using the da Vinci surgical system such as prostatectomy for prostate cancer/partial nephrectomy for renal cell carcinoma/radical cystectomy for bladder cancer), (5) treatment of lower urinary tract dysfunction (benign prostatic hyperplasia, overactive bladder, neurogenic bladder, interstitial cystitis, etc), (6) implantation of artificial urethral sphincter, (7) reconstruction of the urinary tract (construction of neo-bladder, bladder augmentation, pyeloplasty, closure of vesico-vaginal fistula or uretero-vaginal fistula, etc), (8) treatment of the disorders in the field of female Urology (stress urinary incontinence, pelvic organ prolapse, etc), (9) regenerative treatment in Urology field, (10) urinary care for the elderly people (refer to the home page of Nagoya University Continence Information Center: www.med.nagoya-u.ac.jp/haisetsu/). We are also conducting clinical and basic researches in these fields.

Research Projects

1. Basic research for regeneration of the lower urinary tract using adipose-derived stem cells (ASCs)
i) Tissue engineering of the lower urinary tract using adipose-derived stem cells
 The lower urinary tract is regenerated by a Scaffold Free-Bio 3D printer using human adipose-derived mesenchymal stem cells (Adipose-derived Stem Cells; ASCs), which is low-serum cultured. We already constructed the urethra and successfully implanted it to a nude mouse.

ii) Treatment of interstitial cystitis using ASCs with mannose
 We confirmed the improvement of bladder function, bladder pain, blood flow in the bladder and urothelial construction (by immunostaining and electron microscopic findings) in an interstitial cystitis model rat by intravesical instillation of human adipose-derived stem cells with mannose. We are continuing the research aiming at clinical application of this regenerative treatment modality.

iii) Basic research for regeneration of urethral sphincter function using autologous adipose-derived stem cells
 Adipose-derived stem cells (ASCs) are injected to the periurethral space and external urethral sphincter to improve the urethral sphincteric function. By the injection of ASCs, we confirmed an increase of the urethral resistance. In addition, the injected ASCs differentiated into the smooth muscle and produced cytokines such as VEGF and HGF. Since the treatment of stress incontinence by the injection of ASCs would be indicated to the patients undergoing radical prostatectomy for prostate cancer, the effect of ASCs to the growth of prostate cancer cells was investigated. Co-culture of ASCs with prostate cancer cells demonstrated a decrease of PSA level in the medium. Subcutaneous transplantation of prostate cancer cells into a nude rat with ASCs decreased the size of the tumor. These results suggested that ASCs do not have promoting effect of prostate cancer cells.

iv) We are conducting other variety of researches for regenerative treatments, such as regeneration of the kidney using ASCs and treatment of lower urinary tract dysfunction using dental pulp-derived mesenchymal stem cells.

2. A first-in-man study of treatment of stress urinary incontinence by periurethral injection of autologous adipose-derived regenerative cells (ADRCs)
 Approved by the Nagoya University Ethics Committee and the MHWL, we conducted a clinical study to treat stress urinary incontinence caused by the urethral sphincter deficiency by the periurethral injection of ADRCs. This was a first-in-man clinical study of regenerative treatment to treat the urethral sphincter deficiency using ADRCs. In the treatment of 14 male and 4 female patients, the amount of urine leakage decreased and one patient obtained complete continence. In addition, the blood flow in the injected area progressively increased and urethral function was also improved.

3. Investigator-initiated multicenter clinical trial of periurethral injection of autologous ADRCs for stress urinary incontinence due to the urethral sphincter dysfunction caused by prostatectomy
 We started the investigator-initiated multicenter clinical trial for the periurethral injection of the autologous adipose-derived regenerative cells approved by the PMDA. Kanazawa, Shinshu and Dokkyo University participated in this clinical trial, with Nagoya University being the center institute. We aim at completing the clinical trial until 2018 and obtaining an approval by the MHWL and coverage by the national insurance.

4. Basic researches on lower urinary tract dysfunction
 In a variety of animal models of the lower urinary tract dysfunction such as prostatitis model rats, interstitial cystitis model rats and bladder outlet obstruction model rats, basic researches to investigate the new treatment modalities are conducted. In particular, experimental studies for a gene therapy using HSV vector concerning TRIPV1 and NGF are ongoing. The effect of bladder ischemia and oxidative stress on the lower urinary tract function, and treatment of these conditions are also the target of the investigation.

5. Application of the multidisciplinary computational anatomy to predict the renal function before surgical intervention.
 We are trying to elucidate a renal compensation mechanism, to explore a prognostic factor of renal function and to establish a predictive model for renal function using the multidisciplinary computational anatomy. For example, by using this method, we could establish a surgical simulation model to minimize the postoperative renal function loss before the partial nephrectomy for renal cell carcinoma.

6. Elucidation of clinicopathological prognostic factor in prostate cancer.
 We found that intraductal carcinoma in the prostatic cancer tissue was a strong prognostic factor for the patients with prostate cancer in cooperative study with Prof. Tsuzuki of Department of Pathology, Aichi Medical school. We are further investigating the clinicopathological role of intra-ductal carcinoma in relationships with surgical treatment, hormonal therapy and chemotherapy.

7. Clinical studies for the treatment of the disorders in the Urological fields.
 A variety of clinical studies of high evidence level (the sample sizes > 200-300 patients) are conducted in Nagoya University Urological group. Our group also has a large number of surgery patients; radical prostatectomy for prostate cancer of >800 cases / year, nephrectomy for RCC of >300 cases / year, radical cystectomy for bladder cancer of >150 cases/year. We also operate on many patients in the urogynecological field such as pelvic organ prolapse and stress urinary incontinence (more than 500 cases / year) and conducting clinical studies.
