    Analysis of Suprapubic and Transrectal Measurements in Assessment of Prostate Dimensions and Volume Is Transrectal Ultrasonography Really Necessary for Prostate Measurements?
    (UROL & NEPHROL RES CTR-UNRC, 2009) Ozden, Eriz; Gogus, Cagatay; Kilic, Ozcan; Yaman, Onder; Oezdiler, Erol
    Introduction: The objective of this study was to evaluate the correlation of suprapubic ultrasonography and transrectal ultrasonography in measurements of prostate dimension and volume. Materials and Methods: One hundred consecutive patients with lower urinary tract symptoms were examined by suprapubic and transrectal ultrasonography modalities in a same session. Measurements of the 3 dimensions of the prostate (anteroposterior, transverse, and craniocaudal) and its volume performed by suprapubic ultrasonography were compared with the corresponding measurements by transrectal ultrasonography in order to determine the correlation of the measurements. Prostate volumes were calculated using the ellipsoid formula. Data were further analyzed in subgroups according to prostate volumes smaller or larger than 50 mL, measured by suprapubic ultrasonography. Results: The mean prostate volume of the 100 patients, measured by suprapubic and transrectal ultrasonography were 65.9 +/- 35.8 mL and 62.5 +/- 32.0 mL, respectively (r = 0.94; P < .001). The craniocaudal diameters had the strongest correlation among dimension measurements (r = 0.89; P < .001). Suprapubic and transrectal ultrasonography measurements also showed significant correlations for both prostates smaller or larger than 50 mL. Eighty-five percent of the patients had both volume measurements under or above this limit. Conclusion: There was strong correlation between suprapubic and transrectal ultrasonography measurements of the prostate sizes, including both for volume or specific dimension measurements.

    Histomorphological Differences of Spermatic Cords regarding Subinguinal versus Inguinal Levels: A Cadaveric Study
    (KARGER, 2009) Tuccar, Eray; Yaman, Onder; Erdemli, Esra; Zeyrek, Tugba; Esmer, Ali Firat; Kilic, Ozcan; Avunduk, Mustafa Cihat
    Aim: Varicocele is a common disorder among male population and is the most common cause of secondary infertility. Microsurgical inguinal or subinguinal operations are the preferred approaches but the two differ in technical difficulty. Therefore, we examined the histomorphological differences of spermatic cords at both subinguinal and inguinal levels in this cadaveric study. Methods: Spermatic cords from 9 adult male cadavers were examined at both the inguinal and subinguinal levels using a light microscope with an image analysis program in the anatomy and histology laboratories of Ankara University Medical School between July 15, 2006 and February 15, 2007. Results: In terms of number and wall thickness, we did not observe any significant histomorphological differences in spermatic cord veins and arteries between the subinguinal and inguinal levels. Conclusion: We conclude that the subinguinal approach is not a harder technique than the inguinal approach concerning vessel dissection, but more studies must be made to compare subinguinal versus inguinal varicocelectomy.
