    A rare cause of erectile dysfunction: left ventricular diastolic dysfunction
    (Edizioni Minerva Medica, 2020) Ceyhun, Gokhan; Erbay, Guven
    BACKGROUND: The aim of this study was to investigate the association between left ventricular diastolic dysfunction (LVDD) and erectile dysfunction (ED) without overt cardiovascular disease. METHODS: A total of 80 patients with LVDD and without a history of coronary artery disease were compared with 80 age- and gender-matched healthy controls. The International Index of Erectile Function Questionnaire (IIEF-5) was used to diagnose and grade ED. LVDD and its relation with ED severity were assessed. RESULTS: The mean age, Body Mass Index, total testosterone, low- and high-density lipoprotein cholesterol, and triglyceride levels did not significantly differ between the LVDD and control groups (P>0.05). There was a negative correlation between the stage of LVDD and IIEF-5 score (r=-0.635, P<0.05). Additionally, the left atrial volume index, peak TR velocity and E/e' ratio were independent risk factors for lowering the IIEF-5 score. CONCLUSIONS: This study indicates that LVDD is significantly associated with ED. There were significant associations between the increased severity of ED and the presence of LVDD in middle-aged men.

    Renal Parenchymal Volumetric Expansion Assessed by CT Imaging After Laparoscopic Cyst Decortication
    (Urol & Nephrol Res Ctr-Unrc, 2020) Gultekin, Mehmet Hamza; Yalcin, Ahmet; Erbay, Guven
    Purpose: To delineate the expansion of the renal parenchyma using volumetric CT imaging before and after the laparoscopic cyst decortication procedure and to determine the possible associations between parenchymal expansion and laboratory parameters and cyst volume. Materials and Methods: Thirty-five patients who underwent laparoscopic cyst decortication were included in this prospective study. Abdominal contrast-enhanced CT was performed in all patients in the preoperative and postoperative period. Semi-automatic volume quantification was undertaken offline, and renal parenchymal volumes before and after cyst decortication, as well as serum creatinine and estimated glomerular filtration rate (eGFR) were compared. Results: The changes in serum creatinine and eGFR in the postoperative period were non-significant. The mean postoperative renal parenchymal volumes were higher compared to the preoperative measurements for both observations (P = .014 and .034 for the first and second measurements, respectively). There was no correlation between the volumetric change and the cyst volume (r = -0.18, P = .560). Conclusion: In patients undergoing laparoscopic cyst decortication, post-operative parenchymal expansion can be detected using volumetric CT imaging to confirm the immediate benefits of the procedure.
