Ascending uretero-pyelography in renal failure
Clinical Radiology
|September 1, 1977
Summary
Ascending uretero-pyelography (AUP) is a safe and effective diagnostic tool for patients with undiagnosed renal failure. This study found AUP helpful in diagnosing or ruling out obstructive uropathy, aiding management.
Area of Science:
- Urology
- Radiology
- Nephrology
Background:
- Undiagnosed renal failure necessitates accurate diagnostic methods.
- Ascending uretero-pyelography (AUP) is a potential imaging modality for evaluating renal failure.
Purpose of the Study:
- To evaluate the safety and diagnostic utility of AUP in patients with undiagnosed renal failure.
- To assess complications, including ureteric injury and urinary infection, associated with AUP.
Main Methods:
- Retrospective analysis of 97 consecutive patients undergoing AUP over 13 years.
- Data collected on patient demographics, uropathy status (obstructive vs. non-obstructive), procedure details, and outcomes.
- Assessment of diagnostic yield, complications, and impact on renal function.
Main Results:
- AUP was diagnostic in 46% of patients and ruled out obstructive uropathy in the remainder.
- The procedure was largely performed under local anesthesia, averaging 20 minutes per examination.
- Low morbidity observed, with only two anesthetic complications, no mortality, and no significant ureteric injury or deterioration in renal function.
Conclusions:
- Ascending uretero-pyelography is a safe and valuable diagnostic tool for patients with renal failure.
- AUP provides crucial information for the diagnosis and management of obstructive uropathy and other renal conditions.
- The procedure demonstrates a favorable safety profile with minimal complications in experienced hands.
