Contrast-enhanced voiding US for grading of reflux in adult patients prior to antireflux ureteral implantation.
PURPOSE: To prospectively assess contrast material-enhanced voiding ultrasonography (US) for grading of vesicoureteral reflux (VUR) and to compare results with those of voiding cystourethrography (VCUG) in adult patients undergoing antireflux ureteral implantation. MATERIALS AND METHODS: Thirty-seven consecutive adult patients who had undergone renal transplantation with Politano-Leadbetter (18 patients) or Lich-Gregoire (19 patients) technique were included on the basis of previous urinary tract infections (UTIs) and time elapsed after renal transplantation. Exclusion criterion was current UTI. US was performed by one of two sonologists with injection of saline and microbubble suspension and was recorded on videotape. Sonologists assigned VUR diagnosis in consensus after videotape review. VCUG was performed by one of two radiologists immediately after US. Radiologists were blinded to US findings and assigned VCUG diagnoses in consensus. Contingency table was used to compare US and VCUG. Agreement between US and VCUG was determined with kappa statistics. RESULTS: With VCUG, VUR was diagnosed in 15 patients and not diagnosed in 22 patients. US and VCUG results were in agreement in 14 patients with VUR and 21 patients without VUR. US sensitivity and specificity for detection of VUR were 93% (14 true-positive results in 15 abnormal cases) and 95% (21 true-negative results in 22 normal cases), respectively. Agreement between US and VCUG was 95% (kappa = 0.89, P <.001). In 11 of 14 patients, VUR grades were in agreement for US and VCUG. In three of 14 patients, US indicated a higher grade than did VCUG. VUR was diagnosed in seven of 18 Politano-Leadbetter cases and eight of 19 Lich-Gregoire cases. CONCLUSION: A high rate of agreement was seen between voiding US and VCUG.

The accuracy of voiding urosonography in detecting vesico-ureteral reflux: a summary of existing data.
UNLABELLED: The primary objective of this review was to assess the diagnostic accuracy of voiding urosonography (VUS) in detecting reflux (VUR). As a secondary objective, the reported technical suggestions and diagnostic mistakes were shown to improve the examination protocol and provide the most accurate results. Using a Medline Database search, the published articles comparing the grey-scale (GS) or colour-Doppler (CD) VUS with voiding cystourethrography (VCUG) as the gold standard were selected. Articles were excluded when data were not sufficient to construct 2x2 tables or when the gold standard was different from VCUG. For the analyses of diagnostic accuracy values, 95% confidence intervals were given. Agreements in the results of GSVUS and VCUG and in those of CDVUS and VCUG were determined by Kappa statistics. GSVUS and CDVUS were compared for diagnostic accuracy by the McNemar test. Results showed that the range of GSVUS sensitivity and specificity in detecting VUR was 69%-100% and 86%-97%, respectively. The agreement between GSVUS and VCUG diagnoses ranged from 90% to 97% (K score range 0.61-0.92; P<0.001). The range of CDVUS sensitivity and specificity in detecting VUR was 93%-100% and 86%-93%, respectively. The agreement between CDVUS and VCUG diagnoses ranged from 89% to 96% (K score range 0.77-0.91; P<0.001). One study comparing both VUS modalities with VCUG in the same group of patients, showed that the diagnostic accuracy of CDVUS was significantly higher than that of GSVUS (96% versus 90% of cases correctly classified; McNemar chi squared =4; P<0.05). CONCLUSION: the existing data indicate that false-negative voiding urosonographic diagnoses (8%-31%) and underestimated reflux grading cases using the same technique are related to anatomical conditions, patient cooperation and contrast medium administration. False-positive (3%-14%) and overestimated reflux grading cases using voiding urosonography could be correctly assessed cases. The intermittent nature of vesico-ureteral reflux is better detected by a technique employing a prolonged observation time, such as voiding urosonography. This might question the current role of voiding cystourethrography in the investigation of reflux.

Presacral epidermoid cyst. A case report.
INTRODUCTION: Most of the primitive cystic neoplasms arising in the retrorectal presacral space are congenital. Presacral epidermoid cysts are classified as a type of developmental cysts, resulting from an error during the embryogenesis. They have a slowly-progressive growth that only lately can cause clinically remarkable symptoms. Most patients are middle-aged women. They are often asymptomatic. The discovery is almost always casual. It happens during controls like US, CT MRI, gynecological visit. The surgical treatment must be effected for a correct diagnosis of nature of the lesion and to remove the mass. In fact, infective complications may occur and the increasing volume of the cyst can give clinical symptoms. Posterior approach is indicated for low or mid presacral space tumors; it is the most commonly followed route. The abdominal approach may be adequate for large developmental cysts. CASE REPORT: A case of an incidentally found large presacral epidermoid cyst in a young woman, which was excised through an abdominal approach is reported.
