Abstract: High-volume intravenous urography was performed in 63 women with surgically proven endometriosis. Subtle abnormalities were found in 15.9% of these women. No patient had urologic symptoms, and there was no evidence of hydroureter or ureteral obstruction on the IVP. Long-term follow-up study will be required to determine whether or not these lesions will progress and cause ureteral obstruction.
Which is the apt title for the abstract? option1: Ureteral abnormalities in women with endometriosis. option2: Selective management of blunt splenic trauma.
Output:
Ureteral abnormalities in women with endometriosis.
