Purpose: This study was conducted to evaluate the potential role of shear wave elastography (SWE) in the evaluation of testes in patients with varicocele. Methods: A total of 116 testes of 58 patients with left-sided varicocele and 58 testes of 29 agematched healthy controls were included in the study. The patients' testes were classified into groups A (normospermic) and B (oligospermic) based on the presence of oligospermia. The mean SWE values and volume of the testes with varicocele were compared with the contralateral normal testes of the patients and the testes of healthy controls. Results: The mean SWE value of the left testes in groups A (4.77±1.16 kPa) and B (6.15±1.96 kPa) exceeded that of the healthy controls (3.79±0.94 kPa) (P<0.001). The mean SWE value of the left testes in group B (6.15±1.96 kPa) exceeded that of group A (4.77±1.16 kPa) (P=0.002). No correlation was observed between testicular stiffness and the grade of varicocele (r=0.102, P=0.423). Conclusion: The testes with varicocele were stiffer than the contralateral testes and the testes of healthy controls, and SWE might play an auxiliary role to conventional ultrasonography in assessing pathologic alterations in the testis owing to varicocele.

Introduction-Erectile dysfunction (ED) is a condition that is very common all over the world, concerns about men and causes very important social problems. The aim of this study is to perform quantitative penile corpus cavernosum (CC) stiffness measurements by using SWE for patients with both types of vascular ED.Methods-In our study, we handled the data of 101 participants in total. The average age of the participants was 56.36. We divided the participants after color Doppler US (CDUS) into three groups: normal group (n = 30), arterial insufficiency (n = 51), and venous insufficiency (n = 20). SWE measurements were made in both groups in the CC flaccid (f) and rigid (r) positions, and the results were noted. International Index of Erectile Function (IIEF-5) questionnaire and Erection score (ES) were evaluated.Results-The mean CC f SWE and r SWE measurement values were 20.2 AE 0.8 and 17.15 AE 0.54 kPa, 3.84 AE 0.13 and 2.78 AE 0.11 m/s in the arterial insufficiency group; 15.72 AE 0.58 and 12.52 AE 0.33 kPa, 2.88 AE 0.06 and 2.09 AE 0.11 m/s in the venous insufficiency group; 14.75 AE 0.51 and 13.41 AE 0.36 kPa, 2.63 AE 0.1 and 2.34 AE 0.11 m/s in the control group, respectively. The CC measurement of f SWE and r SWE values as kPa showed significant differences between the groups (P < .001).Conclusion-SWE can provide quantitative data with high specificity and sensitivity while evaluating CC penile stiffness noninvasively. It seems to contribute to the radiological evaluation of ED cases with useful data.

In this study, we aimed to evaluate the frequency of anatomic variations of the paranasal sinus region by using multidetector computerized tomography (MDCT). Methods: Between November 2009 and February 2012, 5832 adult patients (2980 females, 2852 males) with a mean age of 39.1±15.4 years (range; 19-85), who underwent MDCT imaging of the paranasal sinus region, were retrospectively evaluated by using the picture archiving and communication system (PACS). All the images were evaluated by three radiologists. Frequency distribution and descriptive statistics of the variants were analysed. Results: Nasal septal deviation was the most commonly detected variation (59.1%) and most were rightward (26.5%). Middle concha pneumatization was the second most commonly encountered variation (57.2%), whereas nasal septum pneumatization was the third most common one (34.8%). Maxillary sinus aplasia was detected in one patient and it was the least common variation (0.05%). Dehiscence of the maxillary nerve (0.4%) and internal carotid artery (0.5%) and sphenoid sinus aplasia (0.5%) were infrequently encountered variations in our study. Conclusion: It is important for the radiologist to know the anatomical variations of the paranasal sinus region in order to consider their possible pathological consequences. Guiding the surgeon in the preoperative period is essential to avoid potential complications.
