Department of Urology
Urolithiasis treatment.
1.f-URS/RIRS
f-URS: flexible uretero-renoscopy/RIRS: Retrograde intra-renal surgery.
Perform lithotripsy using ureteroscopes through the urethra.
2.PNL/ECIRS
PNL: Percutaneous nephron-lithotripsy/ ECIRS: Endoscopic combined intra-renal surgery.
Perform lithotripsy using both nephroscope and ureteroscope bilaterally from the kidney and urethra.
Our history of endourological stone treatment.
- We have been devoting ourselves to treating urolithiasis since 2003.
We have been performing endoscopic treatments such as transurethral lithotripsy (f-URS/RIRS) and combined percutaneous and transurethral lithotripsy (PNL/ECIRS). - We have been actively offering patients with stone diseases to be treated by endoscopic maneuvers to achieve a “ stone-free “ condition.
- From the beginning, we have been performing laser lithotripsy targeting the entire urinary tract using a flexible ureteroscope (f-URS/RIRS).
- For large renal and ureteral stones, we have been conducting percutaneous lithotripsy to minimize the treatment period (PNL/ECIRS).
*Since 2003, over 5,000 RIRS and 500 cases of PNL/ECIRS have been conducted.
Treatment of lithotripsy (kidney stones and ureteral stones)
・What is urolithiasis?
Stones in the kidney can grow in the kidneys or get stuck in the ureters, causing pain and hematuria. It is a disease that causes various symptoms, such as fever, which is sometimes caused by bacterial infection.
Diagnosis of urinary stones
Ultrasound (swelling of the kidneys), urine examination (confirmation of occult hematuria and bacteriuria), X-ray (abdominal imaging and CT examination) By doing so, find out the severity of stone disease. If you have a fever, draw blood and see if you need emergency surgery. We will diagnose whether or not. When bacteriuria is present, a culture test is performed to determine the type of bacteria.
Treatment of urinary stones
If the pain continues and the pain medication is ineffective, if there is swelling of the kidneys, or if the stones are large. Spontaneous excretion is impossible, so we will suggest the following surgical treatments.
・Transurethral urinary lithotripsy surgery (f-URS/RIRS) → Length of hospitalization: 2 nights and 3 days is standard.
・Percutaneous transurethral lithotripsy (PNL/ECIRS) → standard length of hospitalization: 1 week.
Our advantages for treating Urolithiasis.
1. Active fragment extraction by the surgeon
3. Control intra-renal pressur
5. Make stones to dust using advanced laser equipment
1. Endoscopic lithotripsy
Urolithiasis (kidney stones or ureteral stones) is a painful disease.
Therefore, our department will propose early hospitalization and surgery.
We are working to minimize pain during and after surgery.
2. Urolithiasis: Pain management
Specific Initiatives for Postoperative Pain Countermeasures
- Three anesthesiologists perform anesthesia.
- Endoscopic lithotripsy can be performed with either general anesthesia, epidural anesthesia,
or epidural spinal anesthesia. - An thanesthesiologist performse spinal anesthesia for ureteral stenting.
- For male patients, flexible cystoscopes (cameras of the soft bladder) are actively used.
- In order to reduce the pain of the catheter after surgery, an epidural tube (in which anesthetic is continuously injected) is actively used until the next morning.
- For male patients, urinary catheters with local anesthesia are actively used.
- When removing the ureteral stent after surgery, a flexible cystoscope (soft bladder camera) is used.
3. Urolithiasis: Equipment
- 6 lasers are utilized for stone disease and prostatic hypertrophy surgeries.
- Single-use ureteroneoscopes are ready to use.
- An automatic perfusion system for lithotripsy is adopted to control intra-renal pressure related to postoperative fever.
- In addition to Ho: YAG laser, which is commonly used for lithotripsy, Thulium fiber laser （TFL） is lined up to maximize treatment effect since 2024.
- A flexible and navigable suction ureteral access sheath（FANS devices) is adopted to remove stones and sand.
Benign prostatic hyperplasia: The treatment we aim for
In our department, we can perform three surgeries for benign prostatic hyperplasia
1. Ho: LEP
Surgery to hollow out the prostate gland with a laser
２．CVP
Dissolving the prostate with a laser: Transpiration surgery
３．PUL
(Prostatic urethral lift): Widening the urethra with an implant
(wires implanted in the prostate)
* The three surgeries require appropriate treatment from the doctor depending on the size and shape of the prostate, physical strength, and degree of bladder function.
We recommend it. For more information about the surgery, please see the homepage video.
Benign prostatic hyperplasia performed in our department
Laser Prostate Surgery
Insertion of a camera and laser through the urethra
 Ho:LEP |
 CVP |
|
|
Prostatic Urethral Lift (PUL)
Insert a camera and a single-use instrument through the urethra
- Using a special endoscope, implants (metal and sutures) are implanted in the prostate gland
- It is permanently placed and has the effect of widening the urethra.
Moderate or lower prostate indicated
Our target diseases and medical fees.
- We actively offer patients with stone diseases and enlarged prostate to be treated by endoscopic maneuvers.
- According to our department’s policies, we will charge the medical fees determined by our department for the above treatments.
- If you would like to know an estimate of medical fees in advance, please contact us by e-mail.
