The efficacy of ultrasonography for the detection of upper tract urothelial carcinoma.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeUltrasonography and computed tomography urography are two commonly used modalities to image the upper tracts for the evaluation of hematuria. This study evaluated the efficacy of ultrasonography for the detection of upper tract urothelial carcinoma compared to computed tomography urography as a standard reference.
methodsThis retrospective study included patients with urothelial carcinoma of the renal pelvis and/or ureter who were diagnosed using computed tomography urography and underwent surgical treatment. We calculated the sensitivity of ultrasonography in upper tract urothelial carcinoma diagnosis, further classified the degree of hydronephrosis on ultrasonography, and analyzed the relationship between the sensitivity and the degree of hydronephrosis and tumor location. Additionally, the usefulness of the combination of the screening ultrasonography findings, the presence of gross hematuria, and/or urine cytology was analyzed.
resultsThis study included 136 patients with upper urothelial carcinoma. Ultrasonography in the diagnosis had 45.6% sensitivity, and ultrasonography findings, including the detection of hydronephrosis, were present in 72.8%. The presence of hydronephrosis and tumor location were associated with detection by ultrasonography. The tumor was identified in a total of 134 (98.5%) patients by combining tumor detection and hydronephrosis using ultrasonography with gross hematuria and positive urine cytology as screening.
conclusionUltrasonography showed acceptable sensitivity for upper tract urothelial carcinoma diagnosis. Considering the hydronephrosis findings, ultrasonography is a useful screening tool for upper tract urothelial carcinoma. Additionally, excessive computed tomography examinations can be reduced by adding gross hematuria and positive urine cytology.
