  • the accuracy of noncontrast helical computed tomography versus Intravenous Pyelography in the diagnosis of suspected acute urolithiasis a meta analysis
    Annals of Emergency Medicine, 2002
    Co-Authors: Andrew Worster, Ian Preyra, Bruce Weaver, Ted Haines
    Abstract:

    Abstract Study objectives: We determine the accuracy of noncontrast helical computed tomography (NHCT) compared with that of Intravenous Pyelography (IVP) in diagnosing acute urolithiasis. Methods: Computerized searches of MEDLINE and EMBASE were combined with hand reviews of major journals and of articles from reference lists. Articles were assessed according to a priori criteria for inclusion. Study eligibility was independently assessed by 2 reviewers in a blinded fashion. Test results were combined and analysis of log-transformed data was conducted by using general linear models. Results: No disagreement was found between the 2 investigators in terms of articles that met the inclusion criteria or between the results of the studies. Four studies involving a total of 296 patients met all of the a priori criteria. The pooled positive likelihood ratios (LR+) for NHCT and IVP are 23.15 (95% confidence interval [CI] 11.53 to 47.23) and 9.32 (95% CI 5.23 to 16.61), respectively. The pooled negative likelihood ratios (LR−) for NHCT and IVP are 0.05 (95% CI 0.02 to 0.15) and 0.33 (95% CI 0.23 to 0.48), respectively. The differences between NHCT and IVP were statistically significant for both LR+ ( P =.046) and LR− ( P =.013). Differences among trials were not statistically significant in either analysis ( P =.125 for LR+; P =.114 for LR−). Conclusion: The studies analyzed consistently demonstrated NHCT to be superior to IVP in accurately diagnosing acute urolithiasis, and differences between the 2 tests for both LR+ and LR− were statistically significant.

  • computerised tomography and Intravenous Pyelography in urinary tuberculosis a retrospective descriptive study
    International Journal of Tuberculosis and Lung Disease, 2015
    Co-Authors: Y Wang, G C Qin, Zhuping Zhou, X Dou, Bin Zhu, H Q Guo
    Abstract:

    OBJECTIVE To assess the radiological findings of urinary tuberculosis (TB) in patients from multiple centres to improve understanding of this disease among urologists and radiologists. MATERIALS AND METHODS A total of 192 consecutive patients (98 males and 94 females) with urinary TB underwent computed tomography; 28 of the 192 also underwent contrast agent-enhanced Intravenous Pyelography of the kidney, ureter and bladder (KUB/IVP). RESULTS The most common finding was hydronephrosis, observed in 79.1% of the patients, with 81.4% of the destructive renal lesions identified in the medulla. The numbers of lesions in the dorsal medulla and the lower pole of the renal medulla were greater than those in the ventral, middle and upper poles (P = 0.0361). CONCLUSION Hydronephrosis is a frequently observed radiological finding among patients with urinary TB. Most TB lesions were observed in the renal medulla, especially the dorsal and lower poles of the medulla.
