Use of dual energy CT urography in evaluation of urinary stone and complex cyst.

BACKGROUND: Dual-energy computed tomography scans can provide significant benefits to the urinary system. The aim of this study is to determine the limitations and benefits of using dual energy CT urography in patients with urinary system stones and cysts. METHODS: In the analysis of the images, the virtual noncontrasted images obtained from the combined nephrogenicexcretory phase and the true noncontrasted images were evaluated. The true noncontrast images were accepted as the gold standard for stone detection. RESULTS: Eighty-three different stones were detected in 26 of the 115 patients included in the study. Sensibilities of virtual noncontrast images in detecting urinary system stones were 66.7% and 65.4% according to the first and second radiologists, respectively. In this study, 32 hyperdense cysts were detected. According to iodine map images, there was no enhancement in 26 of 32 cysts; only 5 cysts showed minimal contrast enhancement. One patient could not decide on contrast enhancement. DISCUSSION: As a result, if CT urography is performed with dual energy, it can provide additional information in patients with urinary system disorder.

Use of the forgotten joint score (FJS)-12 to evaluate knee awareness after isolated anterior cruciate ligament reconstruction with and without meniscus repair or partial meniscectomy.

PURPOSE: The aim of this study was to compare knee awareness, based on the FJS-12 score, among three patient groups: Anterior cruciate ligament reconstruction (ACLR), ACLR + meniscus repair and ACLR + partial meniscectomy. The relationship between FJS-12 scores and scores on other instruments (Lysholm Knee Scoring Scale, Tegner Activity Level Scale, KOOS and WOMAC) was also evaluated. METHODS: Forty-three patients were divided into group A (isolated ACLR) group B (ACLR + meniscectomy) and group C (ACLR + meniscus repair). Graft thickness, femoral tunnel width, tibial tunnel width, tibial screw thickness and follow-up time were evaluated in all three groups. The subjective knee scores (KOOS, WOMAC, Lysholm Knee Scoring Scale, Tegner Activity Level Scale and FJS-12) of the groups were then compared. RESULTS: FJS-12 scores of 43 patients were evaluated. The mean age was 26.1 ± 6.5 years (range: 18-40 years). Group A: 23; group B: 9 and group C include 11 patients. The mean FJS-12 score of group B (median: 100 [range: 98-100]) was higher than that the others. Spearman's rho test showed that the FJS-12 is highly compatible with the other scores. CONCLUSION: According to this study, FJS-12 and the other scoring systems showed that ACLR with partial meniscectomy is the most effective surgical method to restore normal sensation in the knee.
