Kidney Stones

Dehydration is the most common cause of kidney stones. This leads to not making enough urine, which in turn can cause the crystallization and making of kidney stones. Most kidney stones start out in the kidney. If that stone drops down into the ureter — the tube draining from your kidney to your bladder — it can be extremely uncomfortable and may block the flow of urine, leading to painful symptoms. Urologist Dr. Nathan Grunewald helps prevent and manage recurrent kidney stones. And if you need surgery, Sauk Prairie Healthcare has the technology and laser capable of treating all stones.

Genitourinary Cancer

The genitourinary system is the collection of organs in your body related to urination. These organs include the kidneys, bladder, ureters, urethra, and adrenal glands. For men, the organs responsible for reproduction — the penis, testicles, and prostate — are also part of the genitourinary tract. Genitourinary cancers are those that originate in one of the genitourinary organs. Urologist Dr. Nathan Grunewald is able to diagnose and treat kidney cancer, bladder cancer, prostate cancer, and testicular cancer.

Men’s Health

Men’s health conditions are quite common, such as enlarged prostate (BPH), prostate cancer, testicular cancer, male infertility, low testosterone, and erectile dysfunction. Numerous treatment options exist today which can help improve your quality of life and may even help save your life. Urologist Dr. Nathan Grunewald will help you feel comfortable talking about your men’s health condition and will work with you to determine your best treatment plan.

Overactive Bladder

Overactive bladder causes a sudden and frequent urge to urinate that feels almost impossible to control. You might also leak urine right after you feel the need to go. Using the bathroom more than eight times in a 24-hour time period is another common symptom of overactive bladder. And needing to urinate two or more times during the night could signify overactive bladder as well. Lifestyle changes, medications and surgery are possible ways to treat overactive bladder.


Urinary incontinence is an involuntary and uncontrollable leakage of urine. Urinary incontinence in men is often related to issues with the prostate. For women, a higher rate of incontinence is seen in those who have had children or undergone menopause. Treatment could include behavioral therapy, medical interventions and/or leakage management. Urologist Dr. Nathan Grunewald specializes in incontinence and provides a comfortable environment for you to discuss your symptoms. He will answer your questions openly and honestly, explain your condition thoroughly, and create a treatment plan just for you — enabling you to live life free from accidents once again.

Recurrent UTI

A urinary tract infection, or UTI, is a bacterial infection that can be located in any part of your body’s urinary system. In both males and females, the urinary system is comprised of the kidneys, ureters, bladder, and urethra. If you have two UTIs in a six-month period, or three UTIs in a 12-month period, most urologic physicians will classify it as a recurrent UTI. Long-term, recurring UTIs can cause complications such as kidney disease or damage, sepsis, or delivering a baby prematurely. Urologist Dr. Nathan Grunewald specializes in conditions of the urinary tract and can offer an accurate diagnosis and effective course of treatment.
