Questions after a CT scan?
Due to hematuria, the patient visited the urology department, where a CT scan of the urinary system revealed several tiny cysts in both kidneys.
One of them appears hyperdense on non-contrast enhanced CT, suggestive of a complicated cyst, Bosniak type II.
The bilateral adrenal glands are unremarkable.
I would like to ask the physician:
1.
How often should renal cysts be monitored?
2.
Is it more appropriate to follow up with urology or nephrology? What are the differences between the two specialties?
3.
Does "bilateral adrenal glands are unremarkable" indicate any issues?
4.
What is the likelihood of this type of renal cyst worsening?
5.
Are there any other specific concerns that need attention? Thank you!

1.
How often should renal cysts be monitored? A: Currently, there are no clinical treatment guidelines that specify a standard follow-up interval, so please follow your clinician's recommendations for monitoring.
2.
Is it more appropriate to follow up with a urologist or a nephrologist? What are the differences between the two specialties? A: You may consider following up with the physician who arranged your CT scan.
The difference between the two specialties is that urology is surgical, while nephrology is medical, thus they manage different types of conditions.
3.
What does "Bil.
adrenal glands are not unusual" indicate? A: It means there are no issues.
4.
What is the likelihood of malignancy for this type of renal cyst? A: According to the literature (Eur Radiol.
2017; 27(6): 2239–2247), the malignancy rates for renal cysts are as follows: Bosniak I (3.2%, 95% CI 0–6.8, I2 = 5%), Bosniak II (6%, 95% CI 2.7–9.3, I2 = 32%), Bosniak IIF (6.7%, 95% CI 5–8.4, I2 = 0%), Bosniak III (55.1%, 95% CI 45.7–64.5, I2 = 89%), Bosniak IV (91%, 95% CI 87.7–94.2, I2 = 36).
5.
Are there any other specific concerns to be aware of? A: The answer to this question varies depending on the individual patient's situation, so it is advisable to consult your clinician.

More Info
Understanding kidney cysts, particularly in the context of a recent diagnosis involving several tiny cysts in both kidneys, is crucial for managing your health effectively. Based on the information provided, let's address your questions systematically.
1. How often should kidney cysts be followed up?
The frequency of follow-up for kidney cysts largely depends on the characteristics of the cysts and any associated symptoms. For Bosniak type II cysts, which are typically benign and have a low risk of malignancy, follow-up imaging is generally recommended every 6 to 12 months. However, your healthcare provider may adjust this schedule based on your specific circumstances, including any changes in symptoms or kidney function.
2. Should follow-up be done in Urology or Nephrology? What are the differences between the two specialties?
Urology and Nephrology are two distinct medical specialties that deal with different aspects of kidney health. Urology focuses on the surgical and medical management of urinary tract disorders, including kidney stones, tumors, and cysts. Nephrology, on the other hand, deals with the medical management of kidney diseases, particularly those affecting kidney function and systemic conditions like hypertension and diabetes. For your case, since you have been diagnosed with kidney cysts, follow-up with a Urologist may be more appropriate, especially if there are concerns about the cysts' characteristics or if surgical intervention is a possibility. However, if you have underlying kidney function issues or systemic conditions affecting your kidneys, a Nephrologist may also be involved in your care.
3. What does "bilateral adrenal glands are not unusual" mean?
This statement indicates that the appearance of your adrenal glands on imaging is considered normal and does not show any abnormalities. The adrenal glands, located on top of each kidney, produce hormones that are essential for various bodily functions. If there were any concerns regarding these glands, your healthcare provider would likely have discussed them with you.
4. What is the risk of malignancy for this type of kidney cyst?
According to literature, Bosniak type II cysts have a malignancy rate of approximately 6%. This means that while the majority of these cysts are benign, there is a small risk that they could develop into something more serious over time. Regular monitoring through imaging is essential to detect any changes in the cysts that may warrant further investigation or intervention.
5. Are there other considerations to be aware of?
Yes, there are several important factors to consider. First, maintaining regular follow-up appointments is crucial for monitoring the cysts and overall kidney health. Additionally, it is essential to manage any risk factors that could affect kidney function, such as hypertension, diabetes, and lifestyle factors like diet and exercise. Staying hydrated and avoiding nephrotoxic substances (such as certain medications and excessive alcohol) can also help protect your kidney health. If you experience any new symptoms, such as increased pain, changes in urination, or blood in your urine, you should contact your healthcare provider promptly.
In summary, understanding the nature of your kidney cysts and the appropriate follow-up care is vital. Regular monitoring, appropriate specialist consultations, and proactive management of your overall health can help ensure that any potential issues are addressed early and effectively. Always feel free to discuss any concerns or questions with your healthcare provider to ensure you receive personalized care tailored to your specific needs.
