Renal hydronephrosis caused by urethral tumors?


Hello Director Zhang,
My mother (51 years old) recently underwent a health check-up (she had no discomfort) and an X-ray revealed that one of her kidneys appeared enlarged.
The physician suspected it might be hydronephrosis.
Subsequently, additional tests were arranged, and a tumor approximately the size of a thumb was discovered in her urethra.
The examining physician mentioned that after finding this tumor, they encountered an obstruction that prevented further internal imaging, so they could not confirm the situation.
They plan to arrange for her to be hospitalized for further evaluation.
The physician informed her that they would first attempt to remove the tumor using an endoscope, and if that is unsuccessful, they would need to perform open surgery.
After returning home, I researched information about urethral tumors, but there seems to be limited literature on the subject, which has caused me concern.
Aren't tumors classified as benign or malignant? What is the typical nature of urethral tumors? Are there any specific precautions we should be aware of? Thank you.

DS, 30~39 year old female. Ask Date: 2008/01/14

Urethral tumors, while relatively rare, can have significant implications for kidney health and overall well-being. In your mother's case, the discovery of a tumor in the urethra, especially following an incident where kidney enlargement was noted, raises several important considerations.

Firstly, it’s essential to understand that urethral tumors can be either benign or malignant. Benign tumors, such as urethral polyps or fibromas, typically do not pose a significant risk to health and can often be removed with minimal intervention. However, malignant tumors, such as transitional cell carcinoma or squamous cell carcinoma, can be more serious and may require more extensive treatment, including surgery, chemotherapy, or radiation therapy.

The relationship between urethral tumors and kidney health is particularly important. The urethra is part of the urinary tract, which includes the kidneys, ureters, bladder, and urethra. A tumor in the urethra can potentially obstruct the flow of urine, leading to complications such as hydronephrosis (swelling of the kidney due to urine buildup) or urinary tract infections. In your mother’s case, the initial suspicion of hydronephrosis indicates that the kidney may already be affected by the blockage caused by the tumor. This situation necessitates prompt evaluation and intervention to prevent further kidney damage.

The diagnostic process for urethral tumors typically involves imaging studies, such as ultrasound, CT scans, or MRI, to assess the extent of the tumor and its impact on surrounding structures, including the kidneys. Cystoscopy, a procedure that allows direct visualization of the urethra and bladder, is often performed to evaluate the tumor and potentially remove it. If the tumor is found to be large or invasive, a more extensive surgical approach may be required.

In terms of treatment, if the tumor is deemed operable, the initial approach may involve endoscopic resection, where instruments are inserted through the urethra to remove the tumor. If this is not feasible, open surgery may be necessary. The choice of treatment will depend on the tumor's size, location, and whether it has invaded surrounding tissues.

As for the prognosis, it varies significantly based on the tumor type and stage at diagnosis. Early detection and treatment generally lead to better outcomes. If the tumor is malignant, additional treatments such as chemotherapy or radiation therapy may be recommended to reduce the risk of recurrence and manage any potential metastasis.

In summary, your mother’s situation requires careful monitoring and intervention. It is crucial to follow up with her healthcare team for further evaluations and to discuss the best treatment options. Additionally, maintaining open communication with her doctors about any symptoms, such as changes in urination, pain, or other concerns, is vital for her health and recovery. It’s understandable to feel anxious about the diagnosis, but being proactive in seeking information and treatment can significantly impact the outcome.
