Our Proven Process for Outstanding Urologic Care
Understanding what happens during your urologic care journey brings confidence and peace of mind. At Modern Urology, our systematic approach blends evidence based medicine with genuine compassion, ensuring you receive exceptional results while feeling valued and supported at every stage.
Your journey begins with a comprehensive initial consultation. We schedule extended appointments because rushed visits lead to missed details and incomplete understanding. Dr. Carolyn Fronczak carefully reviews your complete medical history, current symptoms, lifestyle factors, medications, and personal health goals. This thorough discussion helps identify not only immediate concerns but also opportunities for prevention and long term wellness. We perform detailed physical examinations and conduct appropriate diagnostic testing right in our office, including kidney, bladder, and prostate ultrasounds, urinalysis, and advanced imaging when medically indicated.
Â
After your evaluation, we develop your personalized treatment strategy. This is where Modern Urology’s expertise truly distinguishes us. We offer both surgical and nonsurgical options, always starting with the least invasive appropriate choice for your specific situation. For enlarged prostate symptoms, we provide advanced treatments including Urolift and Aquablation procedures. Patients experiencing urinary incontinence can access multiple solutions such as bladder botox, Bulkamid injections, midurethral sling placement, posterior tibial nerve stimulation, sacral neuromodulation, and E coin technology. Those managing stone disease benefit from precision laser treatments, while Peyronie’s disease patients receive Xiaflex therapy.
Cancer screening and diagnosis utilize the most sophisticated technologies available in modern urology. Our UroNav fusion guided prostate biopsy combines MRI and ultrasound imaging for unprecedented accuracy. We employ comprehensive genomic testing through SelectMDX, isoPSA, 4K score, Decipher genomic testing, and Confirm DX to assess the likelihood of clinically significant prostate cancer. This precision medicine approach empowers you to make well informed decisions based on solid scientific evidence. We also participate actively in clinical trials for bladder pain, interstitial cystitis, and genetic testing for cancer patients, providing access to breakthrough treatments before they become widely available.
Throughout your treatment, we provide continuous support and careful monitoring. Many procedures happen in our comfortable office setting, eliminating hospital visits and their associated stress. We’re committed to making your urologic care seamless and worry free.
Why Choose Modern Urology as Your Boulder Urologist
A Patient Centered Partnership Approach
Selecting the right urologist in Boulder, CO means finding a genuine partner in your healthcare journey. Modern Urology offers a refreshingly different approach to urologic care. Dr. Fronczak, our board certified founder and medical director, believes in treating the whole person rather than just managing symptoms. We listen attentively to your concerns, educate thoroughly about your condition, and collaborate with you to develop treatment plans that align with your personal goals and active Boulder lifestyle.
Established in 2023 and built on over a decade of Dr. Fronczak’s specialized expertise, our practice represents an alternative to impersonal corporate healthcare. Since earning board certification from the American Board of Urology in 2019, Dr. Fronczak has dedicated herself to transforming urologic care through evidence based medicine and compassionate service. We’re independently owned and operated, which means we prioritize your wellbeing over profit margins and bureaucratic protocols. This independence allows us to spend adequate time with each patient and make decisions based solely on what serves your best interests.
Advanced Technology and Root Cause Solutions

Frequently Asked Questions About Boulder Urology Services
What urologic conditions does Modern Urology diagnose and treat?
We provide comprehensive diagnosis and treatment for urologic conditions affecting both men and women, plus specialized male reproductive health care. Common conditions include urinary tract infections, kidney stones, overactive bladder, stress and urge incontinence, benign prostatic hyperplasia, prostate cancer, erectile dysfunction, male infertility, bladder tumors, kidney cancer, and Peyronie’s disease. Our specialties encompass general urology, urologic oncology, female urology, and stone disease management with the most advanced treatment options available.
When should I see a urologist instead of my primary care physician?
Consider consulting a urologist if you experience blood in your urine, recurrent urinary tract infections, difficulty urinating or weak urine stream, frequent nighttime urination, loss of bladder control, persistent pelvic or bladder pain, kidney stones, elevated PSA levels, sexual dysfunction, or concerns about prostate health. Your primary care doctor may refer you to us for specialized evaluation and treatment, though you can also contact us directly to schedule a consultation without a referral.
What can I expect during my first appointment at Modern Urology?
Your initial visit includes comprehensive medical history review, detailed discussion of your symptoms and concerns, and thorough physical examination. We perform in office diagnostic testing such as urinalysis, ultrasound imaging, or other evaluations based on your presenting condition. Dr. Fronczak takes time explaining findings in clear, understandable terms and discussing all available treatment options with their benefits, risks, and expected outcomes. Most patients find the experience comfortable and reassuring, especially since we offer nitrous oxide for anxiety management during procedures.
Does Modern Urology treat women as well as men?
Absolutely. We provide comprehensive urologic care for both women and men. While urology is often associated with male health, women frequently consult urologists for conditions such as recurrent UTIs, overactive bladder, stress incontinence, urge incontinence, pelvic pain, kidney stones, and bladder conditions. Modern Urology offers specialized female urology services including advanced treatments for urinary leakage like bladder botox, Bulkamid injections, midurethral sling procedures, and sophisticated neuromodulation techniques tailored to women’s unique needs.
How does Modern Urology approach kidney stone treatment and prevention?
Our kidney stone treatment approach depends on stone size, location, and composition. Small stones often pass naturally with increased fluid intake and appropriate pain management support. For larger or problematic stones, we offer advanced laser lithotripsy to break stones into smaller fragments that pass more comfortably. We also provide comprehensive metabolic evaluation to identify the underlying causes of stone formation and create personalized prevention strategies including dietary modifications and medical management. Our goal extends beyond treating current stones to preventing future episodes through individualized care plans.
