Abstract

[Ita:]Introduction: The aim of this study was to assess the prevalence of urinary tract involvement diagnosed on transvaginal ultrasound examination in women gynecological cancers. The diagnostic performance of transvaginal ultrasound in detecting ureteral and bladder involvement was also evaluated. Methods: This is a multicenter prospective study. Women with gynecological cancers or recurrence undergoing ultrasound examination were included. Transvaginal ultrasound is simple and non-invasive method. Ureters, vesico-uterine septum, bladder involvement were evaluated. Sensitivity, specificity, positive predictive values (PPV), negative predictive value (NPV) of ultrasound were calculated. Surgery or imaging methods (MRI or CT scan) were considered as reference standard. Results: A total of 569 patients were enrolled and 547 of them had diagnosis of malignancy. 56/547 (10.2%) had a diagnosis of urinary tract infiltration at ultrasound examination. On ultrasound examination, both ureters were clearly visualized in the vast majority of cases (507/547, 92.7%), whereas only one ureter was identified in 21/547 (3.8%) patients and both ureters were not visualized in 19/547 (3.5%). Ultrasound examination demonstrated high specificity (>99.0%) and high NPV (>97.0%) for all ultrasound parameters; sensitivity was good for bladder wall infiltration (83.3%) and for vesico-uterine septum infiltration (80.8%), and low for right (69.23%) and left (65.4%) ureter infiltration. Conclusions: The prevalence of pelvic urinary tract infiltration on transvaginal ultrasound examination in women with gynecologic malignancy was 10%. We believe that pelvic urinary tract assessment plays a key role during transvaginal ultrasound examination, in order to plan the management of patients with gynecologic cancers.
