Department of Urology

Introduction

Patient care at our department

The Department of Urology is responsible for the management of urological diseases in general. In particular, we are working on professional and advanced treatment for the three pillars of urological diseases: urological malignancy, urolithiasis, and dysuria.

We place emphasis on radical cure for the treatment of urological malignancy. In addition to open surgery, we also perform minimum incision endoscopic surgery (MIES). In addition to conventional standard therapies, we also incorporate the latest treatments such as immune checkpoint inhibitors (Nivolumab, Ipilimumab, Pembrolizumab) for metastatic kidney cancer and metastatic urinary tract cancer and Radium-223 treatment for bony metastasis of prostate cancer. Furthermore, we can perform unique multimodal treatments, such as a low-volume cisplatin based chemoradiotherapy with partial resection of the bladder for invasive bladder cancer, and high dose rate radiation therapy (HDR) for local progressive prostate cancer in cooperation with the Department of Radiation Oncology.

For urolithiasis, we can choose the treatment that best suits the patient's condition. For example, we may use a combination of the two surgeries, transurethral ureterolithotripsy and percutaneous nephrolithotomy (Endoscopic Combined IntraRenal Surgery: ECIRS), or the extracorporeal shock wave lithotripsy (ESWL) technique.

For dysuria caused by prostatic hyperplasia or neurogenic bladder, we are able to fully understand the condition through ultrasonic examination and urodynamics examination, after which we perform surgery and administer drug therapy. In the past, we have performed the modified autologos midurethral sling surgery (Yamada procedure), developed in our department, for stress urinary incontinence in women. This treatment provides the option of treatment without using artificial mesh materials.

The outpatient clinic is available Monday to Saturday and closed on Sunday and public holidays. If you are a first visit patient, please complete the reception process between 8:30 am and 11:00 am. Please be aware that we do not accept any new patients without a referral letter. Thank you very much for your understanding.

If you are currently taking any medications, please bring them or a medication record book so that we can have a clear understanding of what you are taking.

To the Medical Institutions

To the medical students and residents

With the rapid aging of the population, there is a growing need for urologists to treat malignant tumors, urinary tract stones, dysuria, and among others. Based on a variety of clinical cases in our department, we aim to advance the comprehensive clinical ability of our urologists, which are translatable anywhere in the world. In addition, we aim to foster a 'Scientific Surgeon' who can conduct clinical research that is useful to patients.
Our strengths:

• Kawagoe is the third largest city in Saitama Prefecture and has recently been attracting the attention of foreigners and tourists. As we are a core university hospital in the region, many patients can visit us and benefit from a wide range of medical experiences.
• Since we are a comprehensive medical center, we practice a wide range of treatments.
• In addition to our surgery treatment options, we have staff who are friendly and helpful and are willing to assist even with academic presentations and thesis preparation.

If you are a resident or medical student who is interested in clinical urology, please feel free to contact us at this department (Chief Okada: okada@saitama-med.ac.jp). Given the lack of manpower that we often experience here in Kawagoe, we encourage the addition of hardworking persons. You are, of course, welcome to come on board after the completion of your training.

Presentations for academic societies and papers in our department in recent years:

We study new tumor markers for prostate cancer, urinary tract cancer, and renal cancer and conduct original clinical research on unknown characteristics of testicular torsion. We have launched a joint research collaboration with the Division of Gene Regulation and Signal Transduction, Saitama Medical University Research Center for Genomic Medicine, and we strive to provide novel results that are translatable and useful to patients.
In addition, our young medical staff have conducted several case reports from our extensive clinical cases. We also offer training for academic presentations and writing papers.
