Summary
Serum creatinine and blood urea levels can help identify patients with benign prostatic hypertrophy (BPH) likely to have significant urinary obstruction on intravenous urograms (IVU), saving costs and reducing radiation exposure.
Area of Science:
- Urology
- Radiology
Background:
- Benign prostatic hypertrophy (BPH) is a common condition in aging men.
- Intravenous urograms (IVU) are used to assess urinary tract obstruction.
- Identifying patients who will benefit from IVU is crucial for efficient healthcare.
Purpose of the Study:
- To determine if pre-operative serum creatinine and blood urea levels can predict significant obstructive disease on IVU in BPH patients.
- To identify cost-effective and radiation-sparing methods for selecting patients for IVU.
Main Methods:
- Retrospective analysis of 120 consecutive patients undergoing prostatectomy for BPH.
- Review of pre-operative intravenous urograms (IVU).
- Correlation of IVU findings with serum creatinine and blood urea levels.
Main Results:
- 78 out of 120 patients (65%) had normal IVUs.
- 42 patients had abnormal IVUs.
- Serum creatinine > 2.0 mg% and Blood urea > 35 mg% were valuable predictors of obstructive disease on IVU.
Conclusions:
- Elevated serum creatinine and blood urea levels are useful indicators for selecting BPH patients likely to have significant obstructive uropathy on IVU.
- This approach can lead to cost savings and reduced radiation exposure for patients.
- Biochemical markers can optimize the use of diagnostic imaging in BPH management.
