Abstract
|
|
|
There have been some pros and cons about the of routine intravenous pyelography in benign prostatic hyperplasia.
Herein we analyzed 196 patients who underwent intravenous pyelography before prostatectomy at Dept. of Urology, Seoul National University Hospital from Jan. 1976. to Dec. 1983. Of 196 patients 140 (72%) showed normal upper tract with cystogram compatible with benign prostatic hyperplasia(Group I), 22(11%) dilated upper tract(Group II), 20(10%) incidental upper tract abnormalities including 9 urolithiasis(Group III), and 14(7%) completely normal findings(Group IV). There was a significant relationship between Group II and serum BUN value. Cystoscopy revealed evidence of prostatic enlargement in 14 cases and other abnormal findings including bladder tumor which were not shown on routine IVPs.
We conclude that intravenous pyelography is not always necessary in diagnosis of benign prostatic hyperplasia when urine analysis and serum BUN are normal Instead, we recommend KUB to observe renal outline and calculi, and preoperative routine cystoscopy to evaluate prostatic enlargement and bladder neck obstruction.
