Kidney Stones: Risk Factors and Preventions

The prevalence of kidney stones in the United States has increased over the last decade. As many as 1 in 10 Americans have a kidney stone at some point in their lives, and every year more than half a million Americans go to emergency rooms for kidney stone related complications.

What are kidney stones?

A kidney stone is a small, hard deposit that forms in the kidneys. Stones occur when the urine concentration of crystal-forming substances—such as calcium, oxalate and uric acid—is more than the fluid in the urine can dilute.

They begin as small crystals and grow into larger masses (stones), which then make their way through the urinary tract. Unfortunately, a stone can get stuck on its way out of the urinary system, resulting in an unbearable pain that comes in waves until the stone eventually passes.

What causes kidney stones?

Genetics is one of the risk factors. If you have family members who had kidney stones, you are at a higher risk of having them yourself. Your risk is also higher if you have had kidney stones in the past.

Dehydration is another major cause of kidney stones, which is why more kidney stones occur in the summer. In fact, kidney stone frequency is known to vary by geographic location, with warmer climates having the highest rates of stone formation.

What you eat and drink makes a huge difference. Drinking enough fluids to make over two liters of urine a day reduces the risk of stone formation. Actually, as a rule, you should always check your urine for signs of dehydration. If your urine is dark or yellow, then you are not drinking enough fluid and run the risk of having stones.

Factors that increase dehydration will contribute to kidney stone formation. For instance, excess salt or sodium in food, such as in processed or fast foods, increase dehydration as the excess salt requires a lot of fluid to excrete. So reducing the sodium in your diet will minimize your risk of stone formation.

How do you know that you have kidney stones?

Kidney stones cause pain by getting stuck in the urinary system. Since the kidneys continue to make urine, which in turn can’t get out due to the blockage, the urine builds up, stretches the kidneys and leads to severe pain.

You will know you have kidney stones when you have severe, excruciating pain that comes in waves. The pain typically occurs in the back and does not get better with a change in position. Patients who have had kidney stones and also delivered children report that the stones are more painful than giving birth. In addition to pain, you may have fever, nausea, and even vomiting.

Kidney stones may require a trip to the emergency room if you have severe pain, nausea, vomiting, and a fever greater than 100.3 degrees. These symptoms constitute a urological emergency because they signal both a blockage and an infection. With the blockage preventing antibiotics from getting out via urine, you can get very sick, very quickly; hence the need for emergency care.

Emergency treatment with IV fluids at a hospital may be necessary if you are having nausea and vomiting to the point of dehydration. Emergency care is also appropriate when you have pain that cannot be alleviated by over-the-counter pain medicine.

What is the treatment for kidney stones?

The treatment for kidney stones depends on the size and location of the stone, and on the clinical stability of the patient. The most common approach is medical expulsion therapy—a conservative approach for healthy patients with stones that are small enough to pass on their own and with no fever or other signs of infection.
With medical expulsion, you are encouraged to drink a lot of fluid to help the stone pass on its own. You are also given medications to control the pain and to accelerate passage. If the stone is 5 millimeters or smaller (about half of your thumbnail), there is a 50% chance it will pass on its own and you will avoid surgery.

If you have severe pain, fever, chills and an inability to drink fluids, you may not qualify for medical expulsion therapy. In that case, a surgical procedure may be needed. There are two common surgical options: (1) ureteroscopy or laser lithotripsy, and (2) extracorporeal shockwave lithotripsy.

Ureteroscopy and laser lithotripsy are fancy ways of saying you go to sleep, a camera is inserted through your urethra to the stone, and a laser is used to break the stone into smaller fragments for removal. Extracorporeal shockwave lithotripsy means you go to sleep and sound waves are sent through your skin to fracture the stone into small pieces that can pass on their own in urine.

The advantage of shockwave lithotripsy is that nothing goes into your body, making it less invasive. However, the disadvantage is that the stone fragments still have to pass on their own, a process which can be painful and uncomfortable.

How do you prevent kidney stones?

1. Increase calcium intake

There is a misconception that increasing dietary calcium increases the risk of calcium oxalate stones. This is not true. In fact, eating more calcium rich foods, such as milk or cheese, ensures the oxalate in the diet binds to calcium. When oxalate binds to calcium in the intestines, it is not absorbed in the bloodstream and ends up in stool.

2. Reduce oxalate rich foods

Foods high in oxalate, such as beets, chocolate, tea, coffee, spinach, kale, rhubarb, nuts and beer contribute to stone formation. You may have to eat smaller portions of these foods alongside calcium-rich foods or avoid them altogether.

3. Stay hydrated

Drinking plenty of water will ensure that substances in your urine are diluted and cannot form crystals. As a rule, strive to drink enough water to pass two liters of urine every day—which is drinking roughly eight standard 8-ounce cups per day. It also helps to include some citrus beverages, such as orange juice and lemonade, as the citrate in these beverages helps to block stone formation.

4. Reduce sodium intake

A high salt or sodium diet increases the amount of calcium in your urine and triggers stone formation. Excess salt also wastes the fluid you take as a lot more fluid is necessary for salt-water balance. Make sure to limit your daily sodium intake to 2300mg or less to reduce your risk of kidney stones.

5. Minimize intake of animal protein

Animal protein, such as red meat, eggs, poultry, or seafood, increases the level of uric acid in the body and may cause kidney stones. A high protein diet will also reduce your urinary citrate—the chemical in urine that prevents stones from forming. You can limit animal proteins or replace them with plant-based proteins.

At Advanced Urology Institute, we offer a range of treatments for kidney stones depending on the severity of symptoms and the type, size and location of the stones. We also run tests to find out why they form and give you advice on how to prevent them.

If you or a relative has had kidney stones, consider meeting with one of our urologists for specific ways to reduce your risk. For more information on kidney stone causes, risk factors, diagnosis, treatment and prevention, visit the Advanced Urology Institute website.

Robotic Surgery Effective in Partial Nephrectomy


Robotic partial nephrectomy involves using an advanced surgical robot to remove part of the kidney, usually the portion with a tumor. Initially, robotic surgery enjoyed tremendous success with surgical removal of the prostate (prostatectomy), but in recent years its usage in kidney operations also has yielded remarkable results. In fact, robotic partial nephrectomy has become the preferred treatment option for most patients with benign kidney tumors, small renal masses and early-stage cancer. During the procedure, tumors are removed with the least possible disruption of the rest of the kidney — a nephron-sparing approach that maximizes post-operative kidney function.

Why is the da Vinci surgical system suited for partial nephrectomy?

The da Vinci surgical robot provides superior maneuverability that is suited for the delicate slicing, cutting and stitching involved in the removal of a portion of the kidney. The surgical robot offers a three-dimensional view of the targeted area, allowing for a broader range of motion of the surgical devices. Urologists using the robot find it much easier to make the complex maneuvers required during the procedure.

Since it uses smaller incisions and doesn’t involve making cuts through bone or muscle, the da Vinci partial nephrectomy causes less scarring and minimal trauma to patients. The recovery time is typically only 2 weeks compared to the 6-8 weeks recovery time after open kidney surgery. Likewise, blood supply to the kidney is blocked for a shorter duration, leading to less overall blood loss and quicker recovery compared to laparoscopy.

How is the robotic partial nephrectomy performed?

During robotic partial nephrectomy, the surgeon makes a series of tiny incisions in your abdomen. The camera and robotic surgical instruments are inserted through these incisions. To create enough room for manipulation of the surgical instruments and enable easy access to the cancerous tissue, the abdomen is inflated with gas (carbon dioxide gas). The doctor then moves the colon away from the kidney and trims off the fat covering the kidney to expose the kidney surface.

With the kidney exposed, the surgeon halts the blood flow to the kidney temporarily to prevent potential bleeding as the tumor is cut and the remaining portion of the kidney sutured together. At the end of the procedure, the urologist reconstructs the kidney, restores blood flow and then inspects the kidney carefully to make sure there is no bleeding.

Who should undergo robotic partial nephrectomy?

The da Vinci partial nephrectomy is the surgical treatment of choice for patients with smaller kidney tumors, usually not bigger than 4 cm in size. However, even patients with tumors ranging from 4 cm-7 cm also may undergo the procedure if they are to be treated in certain areas. Similarly, robotic partial nephrectomy is appropriate in cases where removing the whole kidney could trigger kidney failure or the need for dialysis.

At Advanced Urology Institute, we perform hundreds of robotic partial nephrectomy every year with amazing results for our patients. The procedure takes a short time, reduces the problems caused by benign or small kidney tumors and is effective in helping patients recover from kidney cancer. The minimally-invasive nature of the procedure guarantees less scarring, minimal trauma and quicker recovery for our patients. But we always ensure that patients are closely monitored for post-operative pain and complications, accomplishing cancer-free and happier lives for our patients.

What Does Dr. Nicole Szell Say About Women’s Urinary Incontinence?

KEY TAKEAWAYS:

  • Urinary incontinence in women can be classified into different types, such as stress or urge incontinence, which require different treatment approaches.
  • Treatment for urinary incontinence can involve lifestyle changes, pelvic floor exercises, medications, and in some cases, surgery.
  • It’s essential to consult a urologist for appropriate diagnosis and treatment for urinary incontinence to improve symptoms and quality of life.

When you complain to us about urinary incontinence, we will take quick vital steps to help you. For instance, if you are able to immediately provide a clean-catch urine sample, we will do a urinalysis to rule out urinary tract infection. We also will ask you to keep a three-day voiding diary to enable us to classify and identify the cause and severity of your incontinence. Then we will schedule a follow-up visit before we begin treatment to review the timing, quantity, severity and circumstances of your typical episodes of urine leakage, particularly those that you find most troubling.

Types of Urinary Incontinence

The treatment approach we adopt for each case depends on the type of incontinence and severity of symptoms. In women, the most common types are stress or urge incontinence, but some women may have mixed incontinence, where urge and stress incontinence occur simultaneously. When episodes of urine leakage occur following a physical act like sneezing, coughing, heavy lifting or bending over, that is stress incontinence. On the other hand, urine loss associated with a strong uncontrollable need to void is urge incontinence. So we will use the three-day voiding diary, medical history, physical exam and any necessary tests to determine what type of incontinence you have in order to administer the right treatment.

Lifestyle Changes

Once the type of incontinence is determined, we will embark on appropriate treatment for your condition. For example, if we find that you have early-stage incontinence with rare or less troubling symptoms, we will reassure you that your condition is not that bad and recommend a number of lifestyle changes to improve your situation. We are good at building close and abiding relationships with our patients, so we will explain the diagnosis caringly and instruct you compassionately on what lifestyle changes we want you to make. For instance, since timed voiding is quite helpful with nocturnal urge incontinence, we may instruct that you set an alarm every night an hour before the usual time you wake up with a deep sense of urgency and empty your bladder before it gets full to the point of leakage. We also may advise that you reduce your overall fluid intake, avoid caffeine, spicy foods or carbonated drinks.

Pelvic Floor Exercises

We often recommend Kegel (pelvic floor) exercises for women with stress incontinence. Well-timed, regular Kegel and bladder retraining exercises help to relieve symptoms and treat the condition. We will instruct you on the right technique for these exercises and work with you on a plan to help you practice them until they become second nature. We recommend that you begin by exercising the pelvic floor muscles 4 times a day and gradually increase this to 8 times a day, making sure also to use bladder retraining exercises to increase the interval of time you take between your bathroom visits. We will guide you all the way, checking on you to find out if there is any relief from the symptoms as you implement the exercise regimen.

Anticholinergic Medications

In case of a severe, debilitating urinary incontinence with very bothersome and embarrassing symptoms, we may give anticholinergic (anti-muscarinic) medications to eliminate bladder spasms and relieve the symptoms of incontinence. Some common medications we may recommend include Detrol, Vesicare, Ditropan XL, Enablex, Urispas and Oxytrol, with Oxytrol being available even without prescription. Apart from medications, we may advise you to use absorbent pads, panty liners or similar products, to prevent urine leakage or possible embarrassment from a potential leakage. A good example is the pessary, a plastic insert into the vagina, which we may recommend for supporting your bladder’s neck and preventing urine leakage associated with stress incontinence.

Surgery

If these treatments fail to give enough relief, we may opt for surgery. For instance, we may surgically implant small nerve stimulators just beneath your skin to stimulate the nerves controlling the pelvic floor area and manipulate the contraction of the muscles within your pelvic floor. Or we may opt for the sling procedure, a surgical intervention in which a strap of natural tissue or synthetic mesh is added to support the urethra. We also may conduct procedures to restore your bladder to its original position.

Are you worried about urine loss when you sneeze or cough? Do you always have to stop what you are doing and rush to the bathroom whenever your bladder is full? Or do you fear going out with your friends because of a possible urine leakage? Do not suffer in silence. At Advanced Urology Institute, we have been treating urinary incontinence in women for many years and have the tools and personnel to solve your problem. Whether you just started having urine leaks recently or have had the problem for so long that you have decided to avoid the social activities you used to love, we will give you the right treatment to help you recover.

Hi, I’m Dr. Nicole Szell, I’m a board certified urologist with Advanced Urology Institute.

I think the first thing that’s really important to understand when a patient comes in with these issues is how debilitating is it for them?

Are they in the early stages, it doesn’t bother them that much, they just need to be reassured that it’s something that happens to a lot of women, it could get worse, or it could remain the same, or is it become so debilitating to them that they are willing to have surgery or other invasive maneuvers in order to help prevent it.

Webb McCanse Becoming a Urologist

Are you blessed with a great sense of humor? Do you have the courage to openly talk about sensitive and awkward issues? Or are you just interested in helping very sick people get better? If so, you are just like me and an ideal person to serve as a urologist. People feel uneasy about seeing urologists because the issues we tackle are in an uncomfortable area of the body. But as a urologist, you are always called upon to make patients open up and speak about their problems honestly. It is a challenging task, but one that is very satisfying. Who would not feel gratified and fulfilled after smashing the barriers that make people suffer silently from genitourinary disorders and help them to find relief from embarrassing symptoms?

Becoming a Urologist

The opportunity to work in the Navy was very attractive to me. So I pursued medicine as a path to serving my country. With the United States
Navy taking care of my fees, I completed my medical school training at the University of Kansas and joined the University of Nebraska’s Medical Center for a six-year urology residency. Upon completion, I served in the United States Naval Hospitals of Pensacola and Guam, with sporadic assignments in Cuba and Okinawa, Japan. Following a satisfying naval service, I moved to Advanced Urology Institute.

Areas of Expertise

My extensive training exposed me to a number of advanced technologies and medical procedures. I am an expert in minimally invasive surgical procedures, particularly laparoscopic surgery and robot-assisted surgery for a wide range of genitourinary disorders. At AUI, I see patients with urologic cancers (bladder, penile, urethral and prostate), kidney stones, benign prostatic hyperplasia (BPH), overactive bladder and urinary incontinence, among other conditions. I no longer serve in the Navy, but I am still proud to serve my country by helping its citizens overcome some of the most painful and embarrassing conditions.

Job Satisfaction

Urology is a very interesting profession, with each day presenting new challenges. We educate patients on living healthy lives, achieving their goals and making informed decisions.

My Journey to Urology

Women’s health interested me from a very young age, driving me into many years of service as a volunteer and researcher in various women’s health programs and organizations. So when I went to college, my mind was already made up. I just wanted to pursue female urology and pelvic floor medicine. Being a native of the Midwest and Cleveland, Ohio, I went to Radford University in Radford for my bachelor of science in biology and chemistry. Upon graduation, I joined the College of Osteopathic Medicine, East Lansing, MI, for my medical school degree. Then I went to St. John’s Providence Health System, Detroit, for my urology residency program. I specialized in voiding dysfunction, pelvic floor disorders, sexual dysfunction, urologic reconstruction and pelvic organ prolapse, though I also handle general urology disorders such as kidney stones and bladder cancer.

Job Satisfaction

Urology is a field that challenges the intellect daily. It also inculcates the capacity to develop relationships based on trust. But most importantly, it offers the opportunity to solve women’s health problems, something I have been committed to since I was a young girl. As a urologist, I am able to engage with women in different situations and suffering from various conditions. It is a great privilege to listen to them, help them relax and find hope even in the face of a devastating diagnosis. I love my job because each day offers the chance to relieve discomfort, solve embarrassing conditions and improve the quality of life.
