    Penile Doppler ultrasonography and elastography evaluation in patients with erectile dysfunction
    (2018) Altinbas, Namik Kemal; Tıp Fakültesi
    Purpose: To evaluate the relationship between erection grade, erectile function score, Doppler ultrasonography (US) indexes, and elasticity score (ES) according to Doppler US diagnosis in patients with erectile dysfunction (ED). Material and methods: Real-time strain type penile elastography was performed during penile Doppler US examination for 88 patients with ED. The diagnosis according to Doppler US was determined. Erection score according to the Erection Hardness Grading Scale was evaluated. A scoring for erectile function was performed with the International Index of Erectile Function (IIEF-5), and the Sexual Health Inventory for Men (SHIM) was defined. The relationships, according to Doppler diagnosis, of ES, IIEF-5 score, SHIM scale, and erection score were evaluated. Results: Among the patients, 50 (57%) had abnormal penile Doppler US findings. According to Doppler US findings, patients were classified as normal (n = 38), borderline for arterial insufficiency (n = 4), arterial insufficiency (n = 5), and venous insufficiency (n = 41). The lowest erection hardness grades and IIEF-5 scores were detected in patients with arterial failure. When compared to the normal group, in terms of ES, the arterial failure borderline group and venous failure group had lower scores, and the arterial failure group had a higher score. However, the only significant difference was obtained in the left cavernous body of the venous failure group. Conclusions: Sonoelastography seems to add additional value for determination of stiffness of the penile cavernous body in routine evaluation of ED.

    Sonoelastographic evaluation for benign neck lymph nodes and parathyroid lesions
    (2018) Altinbas, Namik Kemal; Tıp Fakültesi
    Aim: The aim of the study was to evaluate the performance of real-time strain sonoelastography for comparison of perithyroidal lymph nodes of Hashimoto thyroiditis patients, jugular lymph nodes of healthy individuals and parathyroid lesions. Material and methods: Fifty parathyroid lesions (Group 1), 52 lymph nodes in Hashimoto thyroiditis patients (Group 2) and 51 reactive jugular lymph nodes (Group 3) were examined by ultrasound, and elastography was performed for a total of 95 patients. Real-time strain sonoelastography using elasticity score (E-index) was performed. The differences in E-index between the three groups were evaluated. Results: The mean E-index and size of parathyroid lesions were 2.30 ± 0.91 and 13.46 ± 5.69 mm, respectively. Parathyroid hyperplasia was detected by parathyroidectomy in two patients (2/37; 5%) with a total of four lesions (4/50; 8%). The remaining lesions were considered as adenomas. The mean E-index and size in Group 2 were 2.70 ± 0.93 and 7.83 ± 3.35 mm, respectively. The mean E-index and size in Group 3 were 1.88 ± 0.59 and 11.60 ± 4.96 mm, respectively. There were statistically significant differences between the groups in terms of E-index (p <0.01). Conclusions: When reactive jugular lymph nodes, perithyroidal lymph nodes of Hashimoto thyroiditis patients and parathyroid lesions are compared, it seems that strain sonoelastography indices add a benefit to routine practice in the differential diagnosis of parathyroid lesions and benign neck lymph nodes.
