Pyelonephritis (PN) diagnosis relies on clinical symptoms and imaging. Computed Tomography (CT) offers superior detection of complicated PN, including emphysematous changes and abscesses, compared to Ultrasound (USG).
Area of Science:
- Nephrology
- Radiology
- Infectious Diseases
Background:
- Pyelonephritis (PN) is a significant kidney infection requiring accurate diagnosis for effective management.
- Assessing the severity of PN often necessitates advanced radiological imaging beyond clinical and laboratory parameters.
Purpose of the Study:
- To compare clinical and biochemical markers with radiological findings (Ultrasound - USG, Computed Tomography - CT) in patients diagnosed with Pyelonephritis (PN).
Main Methods:
- Retrospective review of 100 Pyelonephritis (PN) patient records from January 2016 to December 2016.
- Comparison of clinical and biochemical data against USG and CT findings.
- Statistical analysis using SPSS version 15.0.
Main Results:
- Pyelonephritis (PN) was more common in females (62%), with a mean age of 48.7 years.
- The classical triad of PN symptoms was present in 87% of patients; 47% had acute kidney injury.
- Computed Tomography (CT) detected Pyelonephritis (PN) in 70% of cases, including 4% with Emphysematous PN (EPN) and 3% with renal abscess, outperforming USG in identifying these complications.
Conclusions:
- The clinical triad of fever, flank pain, and dysuria is common in Pyelonephritis (PN), though urine cultures are often negative.
- Ultrasound (USG) is effective for diagnosing uncomplicated Pyelonephritis (PN), but CT is superior for detecting complications like Emphysematous PN (EPN) and renal abscesses.
