Abstract

Objective: To investigate the success rate and the factors affecting the success of percutaneous nephrostomy catheter reinsertion using the existing percutaneous tract. Materials and methods: Retrospective analysis was performed in 47 adult patients who underwent percutaneous nephrostomy catheter reinsertion through existing tract between December 2020 and December 2021. We reviewed the success rate of the reinsertion, the relationship between that rate, the dislodged catheter size, the indwelling time (time between placement and dislodgement) and the timeline that the original tract can be used for reinsertion procedure. Results: The overall success rate for reinsertion through existing tract was 70.21%. Success rate of reinsertion was associated with longer catheter indwelling times compared to patients who failed reinsertion (82.27 vs 34.21 days, p < 0.001) and shorter reinsertion times compared to patients who failed reinsertion (13.21 vs 65.86 hours, p < 0.001). Receiver Operating Characteristic (ROC) curve analysis demonstrated that the cut-off time for reinsertion was 33 hours, with 84.80 % sensitivity and 85.70 % specificity. Conclusions: Reinsertion of the percutaneous nephrostomy catheters using the existing tract has many advantages over the new tract intervention. Reinsertion can be performed successfully after the first 24-36 hours of dislodgement. Success rates vary based on indwelling and reinsertion times.

Abstract

PURPOSE We aimed to investigate the correlation between the color Doppler imaging (CDI) results and parameters determined by spectral domain optical coherence tomography (SD-OCT) in cases with pseudoexfoliation syndrome (XFS). METHODS 99 participants were included in this prospective study. Retinal nerve fiber layer (RNFL), ganglion cell complex (GCC), optic nerve head (ONH) measurements were recorded. Perfusions of the ophthalmic artery (OA) and central retinal artery (CRA) were determined and resistivity indices (RI) were calculated. RESULTS No statistically significant differences were determined between the groups regarding the RNFL and ONH parameters. Only the minimum GCC thickness value was determined to be reduced in XFS group (n = 49) when compared to the controls (n = 50) (p = 0.018). The OA-RI and CRA-RI values of XFS group were significantly higher than the control group (p

Abstract

Objective: In most of the gynecological studies conducted using the Shear Wave Elastography (SWE) method in the literature, the menstrual cycle period was not taken into account. Current study, we aimed to describe the sonoelastographic features of normal myometrium and ovaries in healthy women and to define their variability during the different phases of the menstrual cycle using the SWE method. Material and methods: All cases were selected from individuals between the ages of 24-31, with regular menstrual cycles and no systemic disease. Each case was called in, 1-5th, 12-16th, 21-24th day of their menstrual cycles and was evaluated by B-mode imaging and SWE in pelvic ultrasonography. The relationship of menstrual phases with uterine and ovarian elasticity was investigated by comparing all measurements made in different menstrual phases. Results: No statistically significant difference was observed between the volume of right and left ovaries in terms (p> 0.05). There was no statistically significant difference in terms of elastography measurements obtained from the uterus, right and left ovaries for each menstrual phase according to Bonferroni Correction (p> 0.0163). Conclusion: Although there was a slight decrease in myometrial SWE measurements in the follicular phase, there was no significant difference regarding the SWE measurements of uterus and ovaries in early follicular, peri-ovulatory, and luteal menstrual stages. Further studies with a large number of participants are needed to suggest whether gynecological studies planned to be carried out with the shear wave elastography method should be planned in a specific menstrual phase.
