Sudden PSA and Testosterone Level Changes After Surgery - Urology

More Info

---

After undergoing a robotic-assisted laparoscopic prostatectomy (Da Vinci surgery) for prostate cancer, monitoring your PSA (Prostate-Specific Antigen) levels is crucial for assessing the effectiveness of the surgery and detecting any potential recurrence of cancer. Your current PSA level of 0.191 ng/mL, which has slightly increased from 0.186 ng/mL, is still considered low and generally indicates that there is no significant residual prostate cancer. Typically, a PSA level below 0.2 ng/mL is regarded as a favorable outcome post-surgery.

Regarding your testosterone levels, the sudden increase from 30.5 ng/dL to 231.43 ng/dL is indeed significant and warrants further investigation. Testosterone levels can fluctuate due to various factors, including hormonal therapy, stress, weight changes, and even the time of day when the blood sample was taken. In men, testosterone levels are usually highest in the morning and can vary throughout the day.
The relationship between testosterone levels and PSA is complex. Testosterone can stimulate prostate tissue, which may lead to an increase in PSA levels. However, after prostatectomy, the prostate gland is removed, which typically results in a significant decrease in PSA production. Therefore, while elevated testosterone levels might theoretically influence PSA levels, in your case, the impact may be minimal due to the absence of prostate tissue.
It is important to note that fluctuations in PSA levels can occur for various reasons, including inflammation, infection, or even recent sexual activity. Since you have undergone surgery, it is also possible that the body is still adjusting hormonally, which could contribute to the observed changes in testosterone levels.
In your situation, it would be prudent to continue monitoring both PSA and testosterone levels over time. Regular follow-ups with your healthcare provider will help determine if these fluctuations are part of a normal recovery process or if they indicate a need for further evaluation. If your PSA levels continue to rise or if there are significant changes in your testosterone levels, additional testing may be warranted to rule out any underlying issues.

In summary, while a sudden increase in testosterone levels can potentially affect PSA levels, the absence of the prostate gland after surgery typically mitigates this effect. Your current PSA levels remain low, which is a positive sign. Regular monitoring and open communication with your healthcare provider will be essential in managing your health post-surgery.
