A Modified Approach of Cystic Puncture With Contrast Medium Injection for Diagnosis of Obstructed Hemivagina and Urinary Tract Anomalies

This study investigated the diagnostic value of a modification of the conventional technique of X-ray imaging after cystic puncture with injection of contrast medium for obstructed hemivagina and related urinary tract anomalies in girls. The modified procedure made the following diagnostic findings: ipsilateral obstructed hemivagina in one patient with renal agenesis; vaginal ectopic ureter and ipsilateral obstructed hemivagina in one patient with renal dysplasia; and vaginal ectopic ureter, Gartner's duct cyst and ipsilat-eral obstructed hemivagina in six patients with renal dysplasia or aplasia. This modified method might have improved diagnostic value over the traditional method, and accurately identify genitourinary tract anomalies. It could therefore serve as an alternative and complementary method of sonography.
