Abstract
Background: A potential complication of gynecologic surgery is ureteral injury, which if unidentified can result in significant morbidity for the patient. Intraoperative cystoscopy is currently used to screen for ureteral injury during pelvic surgery. Color Doppler sonography has previously been reported as a possible screening modality for ureteral injuries in postoperative patients.
Technique: Color Doppler sonography is a minimally invasive procedure that can document ureteral jets. Ureteral jets are episodic flame shaped areas within the color Doppler range that correspond to turbulent flow as urine passes from the ureteral orifices into the bladder. An absent ureteral jet indicates absent flow of urine through the ureteral orifice suggesting ureteral injury proximal to the ureteral orifice. This technique does not require use of dyes or contrast agents for direct visualization.
Experience: We present a series of twenty women where intraoperative transabdominal color Doppler sonography documented bilateral ureteral jets with cystoscopy confirming ureteral patency in all patients.
Conclusion: Transabdominal color Doppler sonography is technically feasible to evaluate for ureteral jets intraoperatively. Larger studies are needed to determine whether color Doppler sonography can be used for intraoperative screening for ureteral injury.
Keywords: Ureteral injury, hysterectomy, color Doppler sonography, gynecologic surgery.

RARE CASES IN GYNECOLOGY-OBSTETRICS
With the development of diagnostic and therapeutic techniques (such as ART techniques) and the immersion of new pathologies (such as COVID19), we are witnessing an increase in the incidence of pathologies that were previously described as rare or exceptional. the practitioner sometimes confronts difficult situations in these cases in diagnostic ...read more
