A better understanding of urogenital tuberculosis pathophysiology based on radiological findings

Renal Tuberculosis in the Modern Era

“…21 Ultrasonography, computerized tomography, and magnetic nuclear resonance will demonstrate grossly distorted ureters, with alternating stenotic and dilated areas, reduced bladder volume, hydronephrosis, and reduced kidneys in advanced disease. 21,22 Intravenous urography may show chalice distortion or cavities suggestive of pelvic lesions of TB and loss of right kidney function. 21,23 CUTANEOUS AND RENAL TUBERCULOSIS There is association between renal and cutaneous TB.…”

Think global, act local: chronic dysuria and sterile pyuria in an Eritrean-American woman

“…In both instances, organisms spread from the lungs to the kidneys via haematogenous dissemination, with subsequent involvement of the ureters and bladder through descending infection of the collecting system and genital organs 43 44. As in this patient, reactivation of latent TB may occur many years after primary infection and most patients have no pulmonary symptoms.…”

Usefulness of computed tomography performed immediately after excretory urography in patients with delayed opacification or dilated upper urinary tract of unknown cause

“…Multiple typical findings of renoureteral tuberculosis were found in one patient in CT: focal infundibular stenosis with dilated calyces, smooth, low density, and long thickening of the ureter and thickening of the bladder wall around the ureteral meatus (Fig. 5) [10]. Positive urine culture for Mycobacterium tuberculosis confirmed the diagnosis.…”

“…[4] Caliectasis with contrast-water levels without contrast in the pelvis [1] Pyelocaliectasis with no ureteral contrast [10] Pyelocaliectasis with no ureteral contrast and suspicious calcification in the ureteral tract [4] Pyelocaliectasis and ureterectasis with ureteral filling defect [12] Pyelocaliectasis and ureterectasis with ureteral stenosis [5] Pyelocaliectasis and ureterectasis with normal filling bladder [1] Pyelocaliectasis and ureterectasis with bladder filling defect [2] Ureteral stenosis with low density, smooth, and long mural thickening suspicious of inflammatory/infectious changes [7].…”

“…Urothelial carcinoma [10] Bladder transitional cell carcinoma [4] Infiltrating periureteral mass [3] and crossing vessels) and follow-up allowed diagnosis in 13 cases. Diagnosis of suspicious benign ureteral stenosis (inflammatory, infectious, postsurgical, postradiotheraphy, or ureteropelvic junction stenosis) was obtained by the clinical history (n = 2), bacterial culture (n = 2) and follow-up, or ureteroscopic biopsy or surgery (n = 4).…”
