Abstract

INTRODUCTION: In this study we aimed to evaluate the efficacy of artificial urinary sphincter (AUS) surgery in the treatment of incontinence especially due to sphincter incompetence after prostate surgery,retrospectively according to surgical outcomes and patient satisfaction. METHODS: In our clinic the data of patients who underwent AUS surgery between 2009 and 2018 were evaluated retrospectively. In order to evaluate the incontinence status of the patients before and after the operation, the success rate of AUS surgery and patients satisfaction after AUS surgery, the ICIQ-SF (International Consultation on Incontinence Questionnaire Short Form), which is a questionnaire for urinary incontinence evaluation before and after the operation, was filled. RESULTS: The mean age of the patients was 67.92 +- 24.08 years and the mean follow-up period was 66.38 +- 11.17 months. Daily amount of pad usage and ICIQ-SF score were 4.23 +- 1.49 and 16.84 +- 4.64 in the preoperative period and 1.33 +- 1.01 and 2.91 +- 0.64 in the postoperative period respectively. When these results were compared, there was a statistically significant difference in terms of both the consumption of pads and the ICIQ-SF score (p

Abstract

OBJECTIVES The aim of this study was to determine the role of semiquantitative strain elastography for differentiation of benign and malignant solid renal masses. METHODS Seventy-one patients with solid renal masses were prospectively examined with ultrasound elastography after grayscale sonography. Strain elastography was used to compare the stiffness of the renal masses and renal parenchyma. The ratio of strain in a renal mass and nearby renal parenchyma was defined as the strain index value. Mean strain index values for benign masses (n = 29; 24 angiomyolipomas and 5 oncocytomas) and malignant masses (n = 42; 34 renal cell carcinomas, 4 transitional cell carcinomas, 3 metastases, and 1 lymphoma) and mean strain index values for angiomyolipomas and renal cell carcinomas were compared. RESULTS There were no significant differences in the mean age of the patients, mean diameter of the masses, and mean probe-mass distance between benign and malignant groups. The mean strain index value ± SD for malignant masses (4.05 ± 2.17) was significantly higher than the value for benign masses (1.43 ± 0.94; P < .05). The mean strain index value for renal cell carcinomas (4.30 ± 2.27) was significantly higher than the value for angiomyolipomas (1.28 ± 1.01; P < .0001). CONCLUSIONS Strain elastography may be a useful imaging technique for differentiation between benign and malignant solid renal masses.

Abstract

Renal leiomyomas are not uncommon mesenchymal neoplasms of the kidney, found in 5% of autopsy specimens and comprising 0.3% of all treated tumors. These tumors arise from the smooth muscle cells of the kidney and are mostly located in the renal capsule. Typical imaging features of renal leiomyomas include a peripheral location, well-defined margins, and hyperattenuation on nonenhanced computed tomography (CT) images. The differential diagnosis of renal leiomyomas includes benign and malignant solid neoplasms of the kidney. Familiarity with typical renal leiomyoma imaging findings may help in the management of these patients and prevent unnecessary surgery.
