Supplementary Material for: Gross Hematuria Is More Common in Male and Older Patients with Renal Tuberculosis in China: A Single-Center 15-Year Clinical Experience

Objectives: This study aimed to investigate the
clinical features of renal tuberculosis and identify the age- and
gender-related differences. Methods: A total of 419
patients at the Peking University First Hospital from January 2000 to
July 2015 were retrospectively reviewed. Data on demographic
characteristics, clinical presentation, complications, laboratory
results, radiologic imaging, surgical procedures, and pathology features
were collected and compared between genders and 3 different age groups
(under 40 years, 41-60, years and over 60 years). Results:
The most common local presentations were lower urinary tract symptoms
(65.2%), flank pain (37.9%), and gross hematuria (26.3%). Constitutional
symptoms were also observed in 38.9% of the patients. Gross hematuria
was more common in male patients (32.2%) and older patients (45.5%).
Flank pain was more common in female patients (43.6%). Patients younger
than 40 years of age had lower frequencies of calcification of the
urinary tract (22.2%) and kidney atrophy (4.2%) in CT. In the
postoperative pathological reports, atrophy (35.9%) and fibrosis (38.5%)
were found to be significantly more common in older patients. Conclusions:
While gross hematuria is more prevalent in older patients and male
patients, flank pain is more common in female patients. Radiological and
pathological features including calcification of the urinary tract,
fibrosis, and kidney atrophy are more common in older patients.
