Kidney Stone Treatment with Flexible Method

This is the first time this method has been applied to a stone of this size.
The patient recovered from a 6 cm kidney stone in one and a half hours.

67-year-old Mürvet Gülbay, who lives in ISTANBUL, got rid of her pain for 5 years with a painless and no-incision operation for one and a half hours. Urology Specialist Faruk Yencilek, who pointed out that the operation performed by the method of breaking stones inside the kidney with a flexible system (flexible) is a first in the world in terms of the size of the stone, said, “Our aim was to pulverize the stones of this size and we succeeded”.

Method of breaking kidney stones in the flexible system (Flexible) implemented in Turkey for nearly 15 years. In the operation performed with a closed method without disturbing the integrity of the body, the kidney is reached by following the urinary tract upwards. The stone in the kidney is pulverized by laser. Stating that he has been applying the flexible method to his patients since 2003, Yeditepe University Hospital Chief Physician and Urology Specialist Prof. Faruk Yencilek said that they have broken such a large stone with the Flexible method for the first time in the world and in our country.

“This big stone, not yet seen in the literature”

Underlining that thousands of patients have been treated with this method without pain and suffering for years, Dr. Faruk Yencilek said, “Over time, our experience in this method we use has increased. In this method, which was initially applied to smaller stones, we reached up to 6 centimeters with the last operation. According to the literature review I conducted, until now, a 6 cm stone was not operated on to clean the kidney stone with a flexible system. The operation Ms. Mürvet underwent is a first. Our main goal was to grind such a large stone into powder and we did just that. We placed a stent inside the kidney to expel small dust. “After one month, the system will be completely cleaned and we will take that stent and finish the process,” he said.

Kidney stones cause chronic kidney failure!

Emphasizing that our country is located in the hot zone called the stone belt, Professor Yencilek said, “Kidney stones are seen in approximately 14 percent of our country. One of the most common causes of chronic kidney failure in Turkey is kidney stone disease. Therefore, they must be treated. If kidney stones are not treated, they progress and damage the kidney. In addition, it should be noted that stones can recur after only one treatment, if not followed up adequately. Cleaning the stones is important in this respect. Just as we are a normal risk group for childhood diseases in childhood, we are starting to be a normal risk group for urological diseases even if we have no complaints above the age of 40. Although stones can be seen at any age, especially everyone over the age of 40 should undergo a urological examination once. People with stone disease and obese in the family should be careful, drink plenty of fluids, exercise should be done instead of adopting a sedentary lifestyle “.

“I can no longer look at the stones”

Mürvet Gülbay, who explained that she had pain in her kidneys for 5 years, said that she always postponed the treatment and took painkillers. Expressing that she went to the hospital immediately after the blood he saw in his urine, Gülbay stated:

“In the examinations, first it was revealed that there was an infection, then a 6 cm stone was detected in my kidney. Some nights I had severe pain that I could not stand, barely making it to the morning. I did not experience any pain during and after the operation. I was discharged from the hospital overnight. I feel so good that I still can’t believe it. I’m passing gravel right now, but I have no pain. I excrete stones out of the urine in powder form. I drink plenty of water. Even words are not enough to describe my happiness.

I regret that I have not consulted a physician until this time. I’m telling everyone that ‘just go right now and have a kidney examination’. I can no longer look at the stones, but I am very good, thank God. I just can’t believe it.”

Tarkan Gülbay, the son who explained that his mother was sleepless at night due to pain, said, “Her pain was very disturbing to my mother. It made her sleepless at night. We helped him as best we could. We immediately took action when we observed blood in urine. We are very happy that she got over the disease comfortably, “he said.


What is Prostate Cancer? What are the Risk Groups?

Focal Therapy in Prostate Cancer

With the newly developed focal treatment, the tumor focus in prostate cancer is burned and destroyed. Yeditepe University Hospitals Urology Department Head Faruk Yencilek states that thus, side effects that can occur in classical surgery and radiation therapy are not observed and the cancer focus can be eliminated.

Prostate cancer, which is quite common in men in the world, ranks first among men in the USA. Every year, 650-700 thousand people in the USA and 350 thousand people in Europe are diagnosed with prostate cancer. Prostate cancer is found in 24 percent of men diagnosed with cancer.

Emphasizing that prostate cancer ranks second after lung cancer in our country, Yeditepe University Koşuyolu Hospital Chief Physician and Urologist Prof. Faruk Yencilek added; “On average, one out of 12 men is diagnosed with prostate cancer. It is estimated that around 30 thousand men in our country each year get prostate cancer. However, only 4-5 thousand of them can be diagnosed. The most important factor in this result is the insufficient awareness of early diagnosis and screening methods. “

Risk Factors That Increase Prostate Cancer

Certain risk factors in prostate cancer are listed as increasing age, ethnicity and genetic factors. The incidence of prostate cancer increases with age. While prostate cancer is seen in one out of 10,000 men under the age of 40, this rate rises to 1 percent in the 40-60 age group. If it is over 60, it is seen in one in eight men. Another risk factor is ethnicity. Prostate cancer is most common in African Americans (black Americans) in the world. This is followed by American whites and European countries.

While prostate cancer is 65 per hundred thousand in Europe, this rate is 37 per hundred thousand in our country. It is seen at least in Chinese, South East Asian countries in the world. Another important factor is genetics.  This disease is a type of cancer that has the potential to be passed on from father to son. If a person has prostate cancer in a first degree relative, that person’s risk of developing prostate cancer is twice as high. The risk increases five times if there are two people in close relatives, and 11 times if there are three.


How Prostate Cancer Develops, How is the Diagnosis Made?

What are the symptoms of Prostate Cancer?

There is no specific finding for prostate cancer. Prostate cancer cannot be diagnosed based on a complaint. Any findings that suggest benign prostate enlargement can also be a finding for malignant prostate cancer. These findings related to benign prostatic enlargement such as difficulty in urination, bifurcated urination, feeling as if there is urine remaining  after urinating, frequent urination at night, can also be a sign of malignant growth. Sometimes people can get prostate cancer without any symptoms.


What Should be Done After Prostate Cancer Diagnosis, What are the Treatments?

Focal Approach to Treatment

Saying that the most important point in patients diagnosed with prostate cancer is the staging of the disease, Yeditepe University Kozyatağı Hospital Chief Physician Prof. Faruk Yencilek also stated: “Because the treatment approach changes according to the stage of the disease. Today, more prostate cancers caught in the early stages (limited to the prostate) brought new treatment approaches with it.

In the past, only surgery or radiotherapy was applied to all organ-limited tumors, but now the concept of “Focal Therapy” has entered the literature and practice in the world. Focal Therapy (HIFU) provides relief from cancer in early stage tumors that do not extend beyond the prostate, while reducing the likelihood of complications of the disease. In other words, in this method, early detected tumor focus in the prostate is burned and destroyed. “

You should know!

* Screening in prostate cancer is done by PSA and rectal examination.

* If cancer is suspected, ask your doctor for Multiparametric Prostate MRI.

* Have your prostate biopsy under mp-MRI guidance.

* If you have prostate cancer, ask your doctor the following questions: Is the cancer local, that is, is it limited to the organ, is it locally advanced (has spread beyond the prostate but has not spread elsewhere), is it metastasized (has spread elsewhere)?

* If local, find out which risk group (low, moderate, high) they are in. If you are in the low and moderaterisk group, be sure to talk about HIFU treatment.


Molecular Imaging and Treatment in Prostate Cancer

What is Ga-68 PSMA PET / CT Used in Prostate Cancer Imaging?

PSMA is a smart molecule used in both imaging and treatment of prostate cancer. Ga-68-PSMA PET / CT is the method used in imaging high-risk prostate cancer and detecting its spread to the body.

Patients with increased PSA (biochemical recurrence) after prostate surgery or radiotherapy may show higher rates of recurrence according to MRI and bone scintigraphy. It is also the most sensitive method in detecting spread (metastases) to lymph nodes, organs and bones. It is also used for patient selection suitable for Lu-177-PSMA treatment of metastatic and hormone resistant prostate cancer.


How is Ga-68 PSMA PET-CT Applied?

With this method, very high amount of radiation is not administered to patients. The procedure takes 30-45 minutes. In conventional FDG PET/CT imaging, sugar metabolism is examined. Many cancers can be detected. However, it doesn’t work very well in prostate cancer. PSMA PET / CT is used only in prostate cancer and is very effective. We use Ga-68 PSMA PET/CT imaging to find and view tumor cells in the body at the molecular level.  


Where Is Ga-68 PSMA Used?

  • In the initial staging of medium and high risk prostate cancer
  • In case of PSA relapse (> 0.2ng / ml) after radical prostatectomy / radiotherapy
  • In the presence of suspicious lesions in other methods
  • In planning Lu-177-PSMA (Lutetium) treatment
  • In radiotherapy planning
  • In study of treatment response

When Is Lutetium (Lu-177-PSMA) Therapy Used in Prostate Cancer?

Lu-177-PSMA (Lutetium) treatment has been used as a new treatment option in the treatment of metastatic and hormone-resistant prostate cancer in recent years. It is a smart molecule that finds prostate cancer cells in the body and enters it. It kills the cancer cell by irradiating inside the cells. In this way, while affecting the tumors, it irradiates the surrounding healthy tissues very little. Damage to normal tissues remains very low. Therefore, this treatment is called targeted therapy with smart molecules.

After Lu-177-PSMA treatment, PSA values ​​decrease more than 50 percent in about half of the cases. During the treatment, the patient does not feel any side effects. After the treatment, a partial decrease in the functions of the salivary glands can be observed.


How is Lutetium (Lu-177-PSMA) Treatment Applied in Prostate Cancer?

Lutetium 177 DOTATATE treatment is usually applied as 3 or 4 cycles at 6-8 weeks intervals. It can be applied up to 6-8 cycles according to the course of the disease, kidney functions, blood values and dosimeter calculations. Patients eligible for treatment are determined by examination by experienced Nuclear Medicine physicians. This treatment is given to patients in a protected special room under the supervision of experienced health personnel, nurses and physicians in the form of slow infusion between 20-30.
