Excretory urography before prostatectomy

Area of Science:

• Urology
• Radiology

Background:

• Benign prostatic hyperplasia (BPH) is a common condition in aging men.
• Urinary retention is a frequent complication of BPH.
• Pre-operative assessment aims to identify potential surgical risks.

Purpose of the Study:

• To evaluate the utility of pre-operative excretory urography in patients undergoing prostatectomy for BPH.
• To determine the incidence and significance of upper urinary tract abnormalities in BPH patients.

Main Methods:

• Retrospective review of pre-operative excretory urograms from 205 patients who underwent prostatectomy for BPH over a 5-year period.
• Correlation of urographic findings with clinical examination and laboratory values (urea and creatinine).

Main Results:

• 74.1% of urographic abnormalities were directly attributable to prostatic enlargement.
• Significant upper tract abnormalities (duplex kidneys, poor renal excretion, small kidneys) were found in 11.0% of cases.
• No upper tract tumors or calculi were identified; abnormalities did not contraindicate surgery if renal function was normal.

Conclusions:

• Routine pre-operative excretory urography provides limited value for managing BPH patients with urinary retention.
• The cost and delay associated with routine urography outweigh its benefits in this patient population.
• Pre-operative imaging should be reserved for cases with specific indications beyond uncomplicated BPH.
