Table 1 Results of PoCUS compared with RRUS for hydronephrosis in 50 patients

From: Evaluation of a short formation on the performance of point-of-care renal ultrasound performed by physicians without previous ultrasound skills: prospective observational study

  RRUS + RRUS −
PoCUS + 19 (38%) 9 (18%)
PoCUS − 0 (0%) 22 (44%)
  Sensitivity: 100% [82–100%]
NPV: 100% [85–100%]
Specificity: 71% [52–86%]
PPV: 68% [48–84%]
  1. PoCUS point-of-care ultrasound; RRUS radiologist’s renal ultrasound; NPV negative predictive value; PPV positive predictive value
