Can renal tuberculosis be transmitted to outsiders

Renal tuberculosis is generally not transmitted to outsiders through daily contact, but there are very few special circumstances that may cause transmission. Renal tuberculosis is a disease caused by infection with Mycobacterium tuberculosis, mainly transmitted through droplets, but the kidneys themselves are not the main excretory organs. If patients with renal tuberculosis only have local renal infection and do not have concomitant pulmonary tuberculosis, they usually do not transmit tuberculosis bacteria through coughing, sneezing, or daily contact. Mycobacterium tuberculosis is mainly transmitted through respiratory droplets, while the probability of bacterial excretion in urinary tuberculosis is relatively low, unless the patient also has active pulmonary tuberculosis or urinary tuberculosis leading to extremely high urine bacterial content. When patients with renal tuberculosis are complicated with active pulmonary tuberculosis, tuberculosis bacilli may be released into the air through coughing or sneezing, causing transmission. In rare cases, if a patient's urine contains a large amount of Mycobacterium tuberculosis and is not cleaned in a timely manner after contact with others, there is also a theoretical risk of transmission. People with low immune function should pay special attention to protective measures when coming into contact with patient excreta.

Preventing the spread of renal tuberculosis requires attention to personal hygiene, avoiding contact with patient excreta, and maintaining indoor ventilation. Diagnosed patients should receive standardized treatment and take medication on time until fully recovered. If close contacts experience long-term symptoms such as low-grade fever and fatigue, they should seek medical examination in a timely manner. There is no need to worry excessively about ordinary social contact, but immunocompromised individuals need to strengthen protection.
