Overview
Early diagnosis of hydronephrosis is important because most of the cases can be reversed if not treated promptly lead to irreversible renal injury.Hydronephrosis is usually diagnosed using an ultrasound scan.
Diagnostic Study of Choice
Study of choice
- Renal ultrasonography is the diagnostic study of choice for the diagnosis of hydronephrosis.[1]
- The following results of ultrasonography is confirmatory of hydronephrosis:[2][3][4][5]
The comparison of diagnostic studies for hydronephrosis
| Test | Positive predictive value | Negative predictive value | Sensitivity |
|---|---|---|---|
| Ultrasonography | 0.77 | 0.71 | 98%[6] |
