    Resistant pediatric priapism: A real challenge for the urologist
    (CANADIAN UROLOGICAL ASSOCIATION, 2015-08-10) ŞEKERCİ, ÇAĞRI AKIN; Sekerci, Cagri Akin; Akbal, Cem; Sener, Tarik Emre; Sahan, Ahmet; Sahin, Bahadir; Baltacioglu, Feyyaz; Simsek, Ferruh
    Priapism in pediatric patients is a rare entity. We present an 8-year-old boy with known cerebral palsy. He came to the emergency department with sustained painful erection for 12 hours. Physical examination showed rigid penis. Blood count and biochemical analysis were normal. Although penile Doppler ultrasound revealed normal arterial and venous flow, cavernosal blood gas was hypoxic. A total of 50 mL of dark blood was aspirated, and 2 mL of 0.001% adrenalin solution was applied to both corpus cavernosum, twice within 20 minutes, which eventually did not achieve detumescence. A distal Winter shunt was performed at the end of which the penis was semi-flaccid. By the 18th hour of surgery, the penis re-gained painful erection status, so an Al-Ghorab shunt was performed. After the Al-Ghorab shunt, the penis was still in the semi-flaccid state. The next day, an angiography was performed and an arteriovenous fistula was discovered and treated by embolization. The flaccid state was achieved and the patient was discharged the day after the embolization.

    Differentiation of ureteral stones and phleboliths using Hounsfield units on computerized tomography: a new method without observer bias
    (SPRINGER, 2017) ŞEKERCİ, ÇAĞRI AKIN; Tanidir, Yiloren; Sahan, Ahmet; Asutay, Mehmet Kazim; Sener, Tarik Emre; Talibzade, Farhad; Garayev, Asgar; Tinay, Ilker; Sekerci, Cagri Akin; Simsek, Ferruh
    To differentiate ureteral stones and phleboliths by measuring density [as Hounsfield unit (HU)] and volume (as mm(3)) of the opacities in the bony pelvis on unenhanced computerized tomography (U-CT). A total of 52 patients, who underwent semirigid ureteroscopy and laser lithotripsy for distal ureteral stone and had isochoronous phleboliths in U-CT, were included. Images were reviewed for density and volume of the opacities. Data were compared, and a cut-off value was defined with receiver operating characteristics curve analysis to differentiate the nature of the opacity. Using the cut-off values of 171 mmA(3) for volume (sensitivity 75 %, specificity 100 %) and 643 HU for density (sensitivity 75 %, specificity 93 %), differentiation between stone and phlebolith was achieved. Differentiation of pelvic opacities needs meticulous observation with certain signs on U-CT. On the other hand, our study offers a new method, with certain cut-off values, such as 643 HU and 171 mm(3), which can be used to precisely predict the actual nature of opacities of interest.

    The Significance of the Contralateral Testis Size Measurement with Ultrasonography in Predicting Monorchism in Boys with Nonpalpable Testicles
    (GALENOS YAYINCILIK, 2017-06-16) ŞEKERCİ, ÇAĞRI AKIN; Sekerci, Cagri Akin; Tanidir, Yiloren; Sener, Tarik Emre; Asadov, Ruslan; Sahan, Ahmet; Tarcan, Tufan; Simsek, Ferruh; Akbal, Cem
    Objective: The aim of this study was to determine the significance of contralateral testis size in predicting monorchism in pediatric patients with unilateral undescended testis. Materials and Methods: The data of patients who underwent surgical operation by a single pediatric urologist for undescended testis between 2013 and 2016 was evaluated retrospectively. The patients were grouped as having monorchism (M), nonpalpable intra-abdominal testis (NPIAT), and palpable undescended testis (PUDT). The dimensions of the testes were measured ultrasonographically and recorded before operation. Patients with nonpalpable testis underwent diagnostic laparoscopy and patients with PUDT underwent inguinal orchiopexy. Results: A total of 57 children with a mean age of 31 (11-60) months were evaluated. Of the children, 12 had M, 9 had NPIAT and 36 had PUDT with a similar mean age (p>0.05). The size of the descended testis was found to be significantly small in NPIAT* and PUDT** groups compared to the M group (*p<0.05, **p<0.001). However, the size of the undescended and descended testes was found to be similar between NPIAT and PUDT groups (p>0.05). Conclusion: The size of the testis in the scrotum might help to localize the position of the undescended testis.
