Overview
Diagnostic Study of Choice
Study of choice
Some of the diagnostic techniques for ectopic kidneys include:
- Ultrasound: This procedure makes use of a transducer that directs painless sound waves to provide an image of the internal organs. This procedure may be performed in a hospital or an outpatient center.
- Intravenous Pyelogram (IVP): This is an x-ray of the urinary tract, obtained following injection of a dye, which travels to the kidney and passes through the urinary tract. Thus, any structural anomalies in the urinary tract can be detected.
- Radionuclide Scan: In this procedure, low doses of radioactive chemicals are injected into the patient to identify the path of the chemical in the organ of choice. Ectopic kidneys can be identified based on the location and any block in the ureters can be detected.
- Magnetic Resonance Imaging (MRI): This technique uses magnets and radio waves to provide images of the internal structures of the body. A contrast dye may be used to detect the internal structures.
- Voiding Cystourethrogram (VCUG): This is a procedure that utilizes a contrast dye in the bladder and the urethra. The dye is injected and the x-ray images are obtained when the bladder is full as well as when the individual urinates. The process of urination determines any issue with the bladder and urethra and if urine is regurgitating into the kidney.
[Name of the investigation] is the gold standard test for the diagnosis of [disease name].
OR
The following result of [gold standard test] is confirmatory of [disease name]:
- [Result 1]
- [Result 2]
OR
[Name of the investigation] must be performed when:
- The patient presents with [symptom/sign 1], [symptom/sign 2], and [symptom/sign 3].
- A [name of test] is positive for [sign 1], [sign 2], and [sign 3] in the patient.

[Name of the investigation] is the gold standard test for the diagnosis of [disease name].
OR
The diagnostic study of choice for [disease name] is [name of the investigation].
OR
There is no single diagnostic study of choice for the diagnosis of [disease name].
OR
There is no single diagnostic study of choice for the diagnosis of [disease name], but [disease name] can be diagnosed based on [name of the investigation 1] and [name of the investigation 2].
OR
[Disease name] is primarily diagnosed based on the clinical presentation.
OR
Investigations:
- Among the patients who present with clinical signs of [disease name], the [investigation name] is the most specific test for the diagnosis.
- Among the patients who present with clinical signs of [disease name], the [investigation name] is the most sensitive test for diagnosis.
- Among the patients who present with clinical signs of [disease name], the [investigation name] is the most efficient test for diagnosis.
The comparison of various diagnostic studies for [disease name]
| Test | Sensitivity | Specificity |
|---|---|---|
| Test 1 | ...% | ...% |
| Test 2 | ...% | ...% |
[Name of test with higher sensitivity and specificity] is the preferred investigation based on the sensitivity and specificity
Diagnostic results
The following finding(s) on performing [investigation name] is(are) confirmatory for [disease name]:
- [Finding 1]
- [Finding 2]
Sequence of Diagnostic Studies
The [name of investigation] must be performed when:
- The patient presented with symptoms/signs 1, 2, and 3 as the first step of diagnosis.
- A positive [test] is detected in the patient, to confirm the diagnosis.
OR
The various investigations must be performed in the following order:
- [Initial investigation]
- [2nd investigation]
