“…Female gender was associated with a higher rate of negative URS. Females have an increased prevalence of pelvic phleboliths on imaging which may be mistaken for urinary stones [21][22][23]. Furthermore, females have a higher prevalence of medullary sponge kidney, which may result in parenchymal calcifications being mistaken for urinary stones [24].…”

Purpose of Review While ureteroscopy (URS) is a common procedure for ureteric stones, this window between diagnosis and treatment leaves the possibility for a 'negative', 'stoneless' or 'diagnostic' URS. We perform a systematic review to look at the rate of 'negative ureteroscopy' and risk factors associated with it. Recent Findings From a total of 3599 articles and 68 abstracts, 4 studies (1336 patients) were selected. The negative URS rate varied from 4 to 14%. Common predictors seem to be female gender, small stones, radiolucent stones and distal ureteric stones. Summary Although infrequent, negative ureteroscopy should be avoided in patients with ureteric stones by performing a lowdose CT scan on the day of surgery. This should especially be performed for females and those with smaller, radiolucent or distal ureteric stones.

“…They occur more often in women, more often on the left, and they increase in number with advancing age. 57,58 The appearance of phleboliths on sonography can mimic ureteral stones, but the use of Doppler can distinguish between the two by determining the presence or absence of venous flow. Pelvic phleboliths are generally considered to be harmless, but on rare occasions, they have been associated with venous thrombosis.…”

The standard for performing an antepartum obstetrical sonogram primarily involves the examination of the fetus; however, both the American Institute of Ultrasound in Medicine (AIUM) and American College of Radiology (ACR) guidelines suggest the evaluation of maternal structures as well. The authors present 35 incidental findings that were discovered on routine antepartum obstetrical sonography. These include abdominal wall, gastrointestinal, reproductive, urinary, and vascular anomalies in the maternal structures. A review of the literature demonstrates that many of these findings have clinical significance, which highlights the wisdom of the AIUM and ACR guidelines, and it also stresses the importance of seeking and reporting them.

“…The major limitation of this technique is the difficulty in differentiating confidently distal ureteral calculi from periureteral pelvic phleboliths. Phleboliths are calcified concretions within a vein wall as a result of thrombosis, and their incidence increases with age [1][2][3].…”

Distinguishing pelvic phleboliths from distal ureteral calculi: thin-slice CT findings

et al. 2004

View full text Add to dashboard Cite

The objective is to evaluate the appearance of phleboliths and distal ureteral stones by determining their roundness and presence of central lucency on thin-slice CT. Seventy-seven patients with pelvic radioopacities at unenhanced CT were selected. Those patients consequently underwent thin-slice CT with 1-mm collimation, a FOV of 10 cm, a pitch of 1:1 and a bone reconstruction algorithm. Three radiologists reviewed all images for roundness and the presence of central radiolucency. No calculi showed central lucency on either imaging technique used. Thin-slice CT revealed central lucency in 60% of phleboliths with 100% specificity. Three of 40 ureteral stones showed round contour. Thin-slice CT revealed a round contour in 97% of phleboliths with 93% specificity. Central lucency is a characteristic finding of pelvic phleboliths on thin-slice CT. This finding can therefore be used in combination with roundness as a problem-solving tool in differentiating phleboliths from distal ureteral stones.
