Overview

As per the report of the WHO, approximately 9 million people worldwide suffer from kidney or renal tuberculosis. Due to organ transplantation, the person goes through immunosuppressive therapies, which weakens their immune system. This is the biggest reason their immune system cannot tolerate infection, which leads to tuberculosis of the kidney. On the other hand, immunocompetent persons are less susceptible to Renal Tuberculosis or kidney tuberculosis. Kidney tuberculosis (TB) is an often overlooked and potentially fatal disease. Understanding the basics of kidney tuberculosis is important to protect yourself and your loved ones better.

What Is Tuberculosis of The Kidney?

Kidney tuberculosis is a serious infection that can be difficult to diagnose. It is usually caused by bacteria that enter the body through a break in the skin or a cut in the mouth or nose. The bacteria responsible for tuberculosis of the kidney (or renal TB) are members of the Mycobacterium tuberculosis complex, which differ from the free-living environmental mycobacteria in that they are obligate pathogens and have stringent growth requirements. They preferentially proliferate in a few sites, the kidney, epididymis, fallopian tube, and brain, and produce localised lesions called granulomata. They can also cause the destruction of the glomeruli and the medullary interstitium and, more rarely, infect the renal papillae.

Tuberculosis of the Kidney Symptoms ( Renal Tuberculosis )

There are no early symptoms of kidney tuberculosis, and most people have no signs or symptoms until they have been diagnosed. The clinical symptoms of urogenital TB are insidious and can be difficult to diagnose and treat. Symptoms can include:

- Persistent fever
- Weight loss
- Night sweats
- Dysuria
- Sterile pyuria
- Hematuria
- Flank or abdominal pain
- Nocturia

These symptoms can also be associated with a genital mass or pelvic tenderness, obstructive urination, and abdominal colic. In addition, patients may develop interstitial nephritis and acid-fast bacilli, which tests can identify.

What Causes Tuberculosis of the Kidney?

Renal or kidney tuberculosis is caused by Mycobacterium tuberculosis and is one of the most common forms of TB. It usually develops in adults, but it is also possible to have kidney TB in children.

Kidney TB is more likely to develop in those with pulmonary tuberculosis. This is because lung TB can spread to the kidneys by lymphatic or hematogenous means. Moreover, if the bacilli have been displaced from the lung by anti-TB drugs, they can spread to the kidneys through the bloodstream.

Tuberculosis of The Kidney Diagnosis

The kidney is a common site of tuberculosis (TB) infection. The risk of renal disease is significantly increased in immunosuppressed individuals, including those on dialysis and recipients of renal transplants. However, diagnosing renal tuberculosis can be difficult and involves using microbiological tests to identify the causative organism from urine or biopsy material on conventional solid media.

Imaging

CT is the most reliable imaging technique to diagnose renal tuberculosis. It helps identify the presence of granulomas or abscesses and for evaluating their location. It is also useful in detecting other complications of tuberculosis.

MRI

In addition, MRI scans can aid in detecting tuberculoma growth, which may help select appropriate antituberculosis drugs and ensure their effectiveness.

Kidney TB can be diagnosed using a variety of clinical, microbiological, molecular, and imaging tests such as x-rays and ultrasounds, which can help determine the site of infection, obtain tissue samples for diagnosis, plan medical or surgical management, and monitor response to treatment.

Tuberculosis of the Kidney Treatment Options

Treatment for kidney tuberculosis includes antibiotics and other medicines. If the condition is left untreated, it can lead to serious complications, such as kidney failure or death.

Medications

Anti-tuberculosis medications are the most common type of treatment for renal tuberculosis. They help fight the infection by killing the bacteria causing it. These medications include Ethambutol, Isoniazid, Pyrazinamide, and Rifampicin. These anti-tuberculosis medicines stop the growth of infectious bacteria and kill them.

Surgery

Surgery is also a common treatment for renal tuberculosis. This involves removing infected tissue or parts of the body (nephrectomy).

Tuberculosis of the Kidney Prevention

The prevention of kidney tuberculosis begins with early diagnosis, which is made possible by regular screening for TB in those with risk factors for the disease, such as a long history of TB or a weakened immune system.

Conclusion

Kidney tuberculosis (or renal TB) is a serious infection that can be difficult to diagnose. If you are suffering from this chronic disease, you must refer to a nephrologist and discuss all the possible treatment options.
