🔹 [10 Surgeries in One Day] Full Operation Room Activity on Saturday – A Day in the Urology OR

6月 21st, 2025

At Kameda Medical Center, the third Saturday of every month is our dedicated “Urology Surgery Day.”

As expected, the operating rooms were in full swing from early morning.

✅ Total Surgeries: 10 Cases in One Day

Robot-assisted radical prostatectomy (RARP): 2 cases Transurethral resection of bladder tumor (TURBT): 2 cases Laparoscopic sacrocolpopexy (LSC): 2 cases Circumcision: 2 cases Flexible ureteroscopic stone removal (fTUL): 1 case Urethral caruncle excision: 1 case

🏥 Why Saturdays?

There are many reasons why patients prefer surgery on Saturdays:

Busy with work during the week Traveling from Tokyo or other distant areas Easier to coordinate pre-op and post-op care Prefer day surgery or short hospital stays

Our weekend surgery program aligns well with the needs of patients balancing work and family life.

🔧 OR “Reserved” for Urology

On this day, the OR was almost fully booked with urology procedures — essentially a “private session” for the urology team.

From morning until evening, surgeries proceeded non-stop, smoothly and safely.

This would not be possible without the incredible support from our anesthesia team, nurses, and clinical engineers. Their coordination and expertise deserve the highest praise.

👨‍⚕️ A Great Opportunity to Train Young Urologists

These intensive surgery days also provide valuable time to operate alongside younger doctors.

We take the time to teach and refine each surgical step, ensuring that our residents steadily improve their skills.

Watching their growth and confidence build is one of the most rewarding aspects of this work.

✨ Closing Thoughts

While 10 surgeries in a single day may sound overwhelming, with a skilled and well-organized team, it becomes a productive and fulfilling experience — both for patients and medical staff.

Weekend surgeries like this represent a modern and flexible approach to healthcare.

We will continue to provide safe, high-quality surgical care while nurturing the next generation of urologists.
The theme: Urinary Continence and Erectile Function Preservation in Robot-Assisted Radical Prostatectomy

4月 16th, 2025

[Conference Presentation Announcement]

Selected for the Annual Meeting Video Award at the Japanese Urological Association!

On April 17, 2025, Dr. Nakazono will be presenting at the Annual Meeting of the Japanese Urological Association.

His work has been selected for the prestigious Annual Meeting Video Award in the video presentation category!

The theme: Urinary Continence and Erectile Function Preservation in Robot-Assisted Radical Prostatectomy

This presentation showcases a highly skilled surgical video that directly addresses the challenging issue of preserving urinary continence and erectile function during robot-assisted radical prostatectomy. It is accompanied by a detailed and meticulously compiled set of clinical data.

“How many years has he been practicing?!” — International surgeons stunned by his skills

When international doctors viewed Dr. Nakazono’s surgery, they were astonished, asking,

“How many years has he been in practice?!”

His precise and delicate technique, particularly in nerve-sparing procedures, has earned widespread recognition. The video reflects not only his technical mastery but also his deep consideration for each patient’s long-term quality of life.

Aiming for “zero thermal injury” to the neurovascular bundles

The featured video focuses on nerve-sparing techniques that aim to preserve erectile function by avoiding thermal damage.

Dr. Nakazono carefully minimizes the use of electrocautery or sealing devices near the nerves, and this is clearly explained in the presentation.

This approach has the potential to significantly improve postoperative outcomes in terms of both erectile function and urinary continence.

Evolving techniques: From open surgery to laparoscopic and robot-assisted approaches

At Kameda Medical Center, we have pursued this theme for many years.

Our approach has evolved from open surgery to laparoscopic and now to robot-assisted techniques.

Yet, the philosophy of “nerve preservation above all” has remained consistent throughout.

To all urologists — Don’t miss this presentation!

Radical prostatectomy is not only about cancer cure but also about preserving postoperative quality of life.

This presentation will offer one ideal approach to that goal — with compelling surgical footage and robust data.

If you’re attending the conference, we strongly encourage you to watch Dr. Nakazono’s presentation.

Don’t miss it — April 17, 2025 (Thursday)!
– A Rare Case of Postoperative Urinary Retention –

4月 3rd, 2025

Can’t Urinate After Prostate Removal?

Recently, we received a call from a patient who had undergone laparoscopic radical prostatectomy and had already been discharged. He reported being unable to urinate—a rare concern following this type of surgery. Fortunately, a local hospital in Shizuoka promptly placed a urinary catheter. Since then, his condition has improved, and after the catheter was removed yesterday, he has been urinating well with almost no leakage. We were relieved to hear that his recovery is progressing smoothly.

Now, you might be surprised to hear about urinary retention after prostate removal. In fact, it’s extremely uncommon. After radical prostatectomy, the more typical issue is urinary incontinence, not difficulty passing urine. Cases of immediate postoperative urinary retention are rare and only occasionally reported in the medical literature.

So, why does this happen?

In rare cases, urinary retention shortly after surgery may be caused by urethral edema (swelling), temporary narrowing at the bladder-urethral anastomosis, or a small hematoma (blood collection). In such situations, forcing urination is not advisable. Instead, the safest and most effective approach is to reinsert a urinary catheter and wait for the inflammation and swelling to subside naturally.

According to the literature, conservative management with catheter reinsertion is the standard of care for such cases (Tewari et al., 2007; Campbell-Walsh Urology, 11th edition).

It’s also worth noting that postoperative symptoms such as urinary leakage or difficulty urinating are typically temporary and improve over time. In this case, the patient regained stable urination early on and had minimal leakage, making this a particularly favorable outcome.

This experience reminded us once again that successful surgery is not just about removing disease—it’s also about supporting patients through recovery and maintaining their quality of life (QOL) by addressing even the smallest postoperative issues with care and attention.

“Record-Breaking Surgery Day at Kameda General Hospital”

2月 19th, 2025

Saturday, February 15, 2025, marked our busiest surgical day yet!

A huge thank you to the anesthesiology team, nurses, co-medical staff, and ward team at Kameda General Hospital for their incredible support.

On this day, we performed three radical prostatectomies:

✅ Two nerve-sparing procedures – one using robotic surgery, the other with laparoscopy

✅ One non-nerve-sparing procedure – unfortunately, preservation was not possible

Nerve Preservation in Prostate Cancer Surgery

Whenever we perform radical prostatectomy, we always consider nerve preservation.

During surgery, we carefully observe:

🔹 The color difference between normal prostate tissue and cancerous tissue

🔹 The firmness of the tissue – infiltrated tissue tends to be harder than normal

🔹 The surgical margin – ensuring complete cancer removal while preserving function

While some cases are straightforward, in more advanced cases, distinguishing cancer from normal tissue becomes difficult. When that happens, the disease is often already in a progressed stage, meaning nerve preservation is no longer an option.

Why Is Nerve Preservation Important?

Most people associate nerve-sparing surgery with erectile function, but it also plays a crucial role in urinary continence.

The best nerve-sparing outcome is when post-surgery function remains unchanged from pre-surgery.

If recovery takes several months, it usually means the nerves sustained some level of damage and are slowly healing.

This is why precise surgical technique is critical—preserving nerve function from the start leads to the best possible recovery.

Surgical Precision Matters

Minimally invasive techniques, whether robotic or laparoscopic, allow for:

✅ Better visualization during surgery

✅ Careful tissue handling to reduce damage

✅ Improved functional outcomes for both erectile function and continence

By refining our techniques and advancing our understanding of nerve preservation, we continue to push for better outcomes for our patients.
