  • Upper urinary tract urothelial carcinoma on multidetector CT: spectrum of disease. [Review]
    Abdom Radiol (NY) 2019Ali O, Fishman E, Sheth S
  • Urothelial carcinoma of the upper urinary tract (UUT) is a relatively uncommon genitourinary malignancy, accounting for about 5-7% of urothelial tumors. The significant features of this tumor are multifocality and high rate of recurrence. Computed tomography urography (CTU) has replaced excretory urography (EU) and retrograde pyelography (RP) for imaging of upper tract urothelial carcinoma. While…
  • [Follow-up surveillance of muscle-invasive urinary bladder cancer after curative treatment]. [Journal Article]
    Urologe A 2019; 58(9):1093-1106Schulz GB, Stief CG, Schlenker B
  • Follow-up care of patients with muscle-invasive bladder cancer is subdivided into oncological and functional surveillance. More than 80% of local relapses and distant metastases occur within the first 2 years. Recurrences in the remnant urothelium also occur several years after radical cystectomy. Urinary cytology and a computed tomography (CT) scan of the abdomen and thorax including a urography…
  • Image quality and pathology assessment in CT Urography: when is the low-dose series sufficient? [Journal Article]
    BMC Med Imaging 2019; 19(1):64Kataria B, Nilsson Althén J, … Sandborg M
  • CONCLUSIONS: Visualisation of renal anatomy was as expected with each post-contrast phase showing favourable scores compared to the native phase. No statistically significant differences in the assessment of pathology were found between the three phases. The low-dose CT (LDCT) seems to be sufficient in differentiating between normal and pathological examinations. To reduce the radiation burden in certain patient groups, the LDCT could be considered a suitable alternative as a first line imaging method. However, radiologists should be aware of its limitations.
