Can kidney tuberculosis be transmitted between couples

There is a possibility of transmission of renal tuberculosis between spouses, but the probability is relatively low. Renal tuberculosis is mainly transmitted through Mycobacterium tuberculosis, with lower infectivity than pulmonary tuberculosis. The main transmission routes include respiratory droplets, close contact, and shared items. If one party suffers from active renal tuberculosis and has open lesions in the urinary system, it may be transmitted through sexual contact or sharing of daily necessities. But in most cases, the number of tuberculosis bacteria in the urine of renal tuberculosis patients is relatively small, and the risk of transmission is relatively limited.

The transmission of renal tuberculosis needs to meet three conditions at the same time: the infectious source has active tuberculosis focus, the transmission route is unblocked, and the immunity of the contact person is low. In daily contact between spouses, if no tuberculosis bacteria are found in the patient's urine test, or if they have received standardized anti tuberculosis treatment for more than two weeks, the infectivity will be significantly reduced. Maintaining personal hygiene, avoiding sharing personal items such as towels, and taking protective measures during sexual activity can further reduce the possibility of transmission. When one spouse is diagnosed with renal tuberculosis combined with urinary tract fistula, purulent urine, or has not received standardized anti tuberculosis treatment, the risk of transmission will significantly increase. In such cases, strict isolation of the patient's secretions is required, and the spouse should promptly undergo screening with a tuberculin test or interferon release test. People with impaired immune function, such as diabetes patients and those who take immunosuppressants for a long time, need to improve their awareness of prevention.

It is recommended that both husband and wife maintain a regular daily routine and balanced diet, and supplement high-quality protein and vitamin A appropriately to enhance immunity. After being diagnosed with renal tuberculosis, standardized anti tuberculosis treatment should be completed for 6-9 months, and regular follow-up urine routine and urine tuberculosis bacterial tests should be conducted during the treatment period. If a spouse experiences long-term symptoms such as low-grade fever, frequent urination, urgency, and lower back pain, they should promptly seek medical attention and examination at the infectious disease department or urology department. Pay attention to opening windows for ventilation in daily life, disinfect patients' clothing and bedding by exposing them to sunlight, and boil shared utensils.
