A52.75
Syphilis of kidney and ureter
Clinical Classification Guidelines
Inclusion Terms
- Syphilitic glomerular disease
Medical Intelligence & Overview
Syphilis of the kidney and ureter, classified under ICD-10 code A52.75, is a rare manifestation of systemic syphilis caused by the bacterium Treponema pallidum. This condition involves the infection of the kidneys and the ureters, which are part of the urinary system. Its most notable feature is syphilitic glomerular disease, where the microscopic filtering units of the kidney are affected. Due to its rarity and subtle symptoms, it can be challenging to diagnose without specific tests, but awareness is crucial for appropriate management and prevention of potential complications.
Causes & Symptoms
Clinical Causes: Primary cause is infection with Treponema pallidum, the bacterium responsible for syphilis. Progression of untreated or inadequately treated syphilis leading to secondary or tertiary stages. Hematogenous spread of the bacteria from the primary or secondary site to the kidneys and ureters. Immune-mediated damage resulting from the body's response to the infection.
Key Symptoms: Asymptomatic in early stages; kidney involvement may be discovered during routine testing. Flank pain or discomfort due to inflammation or swelling in the renal area. Hematuria (blood in the urine) caused by damage to glomeruli. Proteinuria (excess protein in urine), indicating glomerular damage. Systemic symptoms such as fever, malaise, or weight loss in more advanced stages. Signs of impaired kidney function like swelling in the legs or abdomen. Ureteral symptoms may include urinary frequency or discomfort, if the ureters are involved.
Diagnostic & Treatment
Diagnosis Path: Serologic testing for syphilis, including non-treponemal (RPR, VDRL) and treponemal (FTA-ABS) tests. Urinalysis to detect protein or blood in the urine. Renal function tests such as serum creatinine and blood urea nitrogen (BUN). Imaging studies like ultrasound or CT scans to evaluate kidney and ureter structure. Kidney biopsy in uncertain cases to confirm syphilitic glomerular disease and assess tissue damage. Blood tests to exclude other causes of nephritis.
Treatment Protocols: Antibiotic therapy, primarily high-dose penicillin, to eradicate Treponema pallidum. Monitoring of serologic response to ensure treatment efficacy. Supportive measures for kidney function, such as managing hypertension or edema if present. Addressing any ongoing urinary symptoms or complications. Regular follow-up with a healthcare provider to monitor for recurrence or residual damage.
