Dr. Xu Weikai reply Urology


Hello, regarding the relationship between erection and saliva secretion, it's rare for physicians to make such a correlation.
However, if the goal is simply to reduce saliva production, you might consider consulting a neurologist, as there are certain medications that can effectively decrease saliva secretion.
Since this involves neural stimulation, further information may be required.
If there are any unclear points, feel free to ask again, and we can discuss and research further.
This is a response from Dr.
Hsu Wei-Kai, Director of Urology at Taitung Hospital, Department of Health, Executive Yuan.

More Info


Ewing's Sarcoma is a type of bone cancer that primarily affects children and adolescents. It is known for its responsiveness to chemotherapy, with control rates reaching up to 60%. In the case you presented, the 15-year-old boy experienced complications following chemotherapy, specifically bladder inflammation and hematuria (blood in urine), which can occur as a side effect of certain chemotherapeutic agents, particularly if hydration protocols are not properly followed.

1. Potential for Permanent Damage: The acute bladder inflammation and hematuria experienced by the boy are concerning but may not necessarily lead to permanent damage. Acute reactions to chemotherapy can cause temporary issues, and with appropriate management, many patients recover fully. However, ongoing monitoring is essential. If the inflammation persists or worsens, there could be a risk of long-term complications, including bladder dysfunction or recurrent urinary tract infections. The kidneys are typically less affected by bladder issues unless there is significant backflow of urine (reflux) or obstruction, which could lead to hydronephrosis (swelling of the kidney due to urine buildup). The doctor’s assurance that the kidneys are undamaged is reassuring, but continued vigilance is necessary.

2. Kidney Damage Concerns: While the doctor has stated that there is no kidney damage, it is crucial to monitor renal function closely, especially given the boy's symptoms. If the bladder is severely inflamed, there is a possibility of urinary reflux, which could affect kidney function over time. If the boy continues to experience hematuria or other symptoms, further investigation, such as imaging studies or urodynamic tests, may be warranted to assess kidney health and function.

3. Diagnosis Accuracy: Ewing's Sarcoma is typically diagnosed through a combination of imaging studies and histopathological examination of the tumor. While misdiagnosis is rare, it is not impossible. If there are lingering doubts about the diagnosis or treatment plan, seeking a second opinion from a pediatric oncologist specializing in Ewing's Sarcoma is advisable. Different specialists may have varying interpretations of the same pathology, and a second opinion can provide reassurance or alternative treatment options.

4. Seeking a Second Opinion: It is entirely reasonable for the family to seek a second opinion, especially if they have concerns about the diagnosis or treatment. Consulting with a pediatric oncologist who specializes in Ewing's Sarcoma can provide additional insights and confirm the current treatment plan's appropriateness. This can help alleviate any doubts and ensure that the boy is receiving the best possible care.

5. Legal Actions and Hospital Accountability: If the family believes that the hospital's error in administering chemotherapy has led to significant harm, they may consider consulting with a legal professional who specializes in medical malpractice. Documenting all medical records, treatment plans, and communications with healthcare providers will be essential in any potential legal proceedings. Additionally, they can file a formal complaint with the hospital administration to address the issue and prevent similar occurrences in the future.

In summary, while the immediate complications from chemotherapy can be distressing, with proper management and monitoring, many patients recover without permanent damage. Continuous follow-up with healthcare providers is crucial to ensure the boy's health and address any emerging issues promptly. Seeking a second opinion can provide peace of mind and confirm the best course of action moving forward.
