    (2020-01-01) İlktaç, Abdullah; Akbulut, Habib; Akçay, Muzaffer; Ersöz, Cevper; Doğan, Bayram; İLKTAÇ, ABDULLAH; DOĞAN, BAYRAM; ERSÖZ, CEVPER; AKÇAY, MUZAFFER; AKBULUT, HABİB
    Purpose: To assess the relationship between testicular germ cell tumors (TGCT) and neutrophil to lymphocyte ratio (NLR) and to determine whether this ratio can be used as a serum tumor marker. Material and Methods: Sixty-one patients with testicular germ cell tumors were included into the study. Patients were grouped as localized and non-localized. Histologically patients were categorized as seminoma and nonseminomatous germ cell tumors. Complete blood cell count was measured the day before surgery and at the postoperative 1st month. Preoperative and postoperative mean NLR values were compared. Results: Thirty-six patients (59%) had seminomas and 25 patients (41%) had nonseminomatous testicular cancer. Forty-fi ve patients (73.8%) had localized and 16 patients (26.2%) had non-localized testicular cancer. There was a statistically signifi cant difference between preoperative and postoperative mean NLR of the localized patients (p=0.001) but no such difference was detected for non-localized patients (p=0.576). Nineteen patients with localized seminomas had normal preoperative serum tumor markers. There was a signifi cant difference between preoperative and postoperative mean NLR in this group of patients (p=0.010). Twenty-six patients with localized tumors had preoperative increased serum tumor markers which normalized after orchiectomy. Mean NLR of these patients signifi cantly decreased from 3.10±2.13 to 1.62±0.59 postoperatively (p=0.010). Conclusions: NLR appears to be a useful marker for TGCT. It is successful in predicting localized and non-localized disease in early postoperative period.

    Comparison of Scoring Systems in Predicting Success of Percutaneous Nephrolithotomy
    Background: Scoring systems are useful to inform the patients about the success and complication rates of the operation prior the surgery. Aims: To determine the applicability of the popular scoring systems (Guy’s, stone size, tract length, obstruction, number of involved calices, and essence/stone density and Clinical Research Office of the Endourological Society) by means of examining preoperative data of patients treated with percutaneous nephrolithotomy. Study Design: Cross sectional study. Methods: We retrospectively reviewed files of the patients who had undergone percutaneous nephrolithotomy in our center between 2011 and 2015. Excluded from the study were patients aged <18 years, and those who were not assessed preoperatively with computed tomography. Preoperative computed tomography images of all patients were assessed by a single observer, and patients were graded based on three scoring system. Demographic data were analyzed along with perioperative data (operation, fluoroscopy, length of hospital stay, changes in hematocrit values, location, and number of access sites, stone-free and complication rates). Results: A total of 298 patients who had been treated with 300 procedures were enrolled into the study. Mean age, stone burden, number of stones, and density were 48.1±12.9 years, 663.5±442.8 mm2, 1.8±1.1 and 888.3±273 HU respectively. Scores of the cases based on Guy’s, stone size, tract length, obstruction, number of involved calices, and essence/stone density, and Clinical Research Office of the Endourological Society scoring system were calculated as 2, 7.6, and 222.1 points respectively. 81.6% of the patients were stonefree. Complications were detected in 30 (9.9%) patients. Based on receiver operating characteristic curve analysis a positive correlation was detected between success rate and scoring systems, i.e., Guy’s (p=<0.001, r=-0.309), stone size, tract length, obstruction, number of involved calices, and essence/stone density (p=<0.001, r=-0.295), and Clinical Research Office of the Endourological Society (p=<0.001, r=0.426). The Clinical Research Office of the Endourological Society scoring system had the highest predictive value. The sensitivity rates rates for Guy’s, Clinical Research Office of the Endourological Society and Stone scoring system were as 78.78%, 80% and 82.34% respectively. Conclusion: All of scoring systems predicted correctly the success of the percutaneous nephrolithotomy procedures. The Clinical Research Office of the Endourological Society scoring system had the highest predictive value.

    Comparison of intrarenal pelvic pressure during micro-percutaneous nephrolithotomy and conventional percutaneous nephrolithotomy
    (2014-06-01T00:00:00Z) TEPELER, Abdulkadir; AKMAN, Tolga; SILAY, Mesrur Selcuk; Akcay, MUZAFFER; Ersoz, CEVPER; Kalkan, SENAD; ARMAGAN, Abdullah; SARICA, Kemal; AKÇAY, MUZAFFER; ERSÖZ, CEVPER; KALKAN, SENAD
    The micro-percutaneous nephrolithotomy (microperc) is a recently introduced percutaneous nephrolithotomy (PNL) technique that is performed through a 4.8Fr all-seeing needle. We aimed to measure the intrarenal pelvic pressure (IPP) during microperc and compare it with the levels of conventional PNL. A total of 20 patients with 1- to 3-cm renal calculi resistant to shock wave lithotripsy were treated either with microperc (Group-1, n: 10) or conventional PNL (Group-2, n: 10) by the same surgical team. The IPP was measured during different stages (entrance into the collecting system, stone fragmentation, and before termination) of the procedures by an urodynamic machine using the 6Fr ureteral catheter. All the variables were statistically compared between the two groups. The demographic values of the patients were similar. The operation time and duration of hospitalization were significantly prolonged in conventional PNL group (p = 0.034, p = 0.01, respectively). The mean drop in hematocrit levels was significantly lower in microperc group (3.5 +/- A 1.5 vs. 1.8 +/- A 0.8; p = 0.004). The IPP was significantly higher in microperc group during all steps of the procedure. The highest level of the IPP was measured as 30.3 +/- A 3.9 and 20.1 +/- A 3.1 mmHg in Group 1 and Group 2, respectively (p < 0.0001). However, the complication and success rates were found comparable. In conclusion, we demonstrate that the level of IPP is significantly increased during microperc compared to conventional PNL. Microperc should be used cautiously in cases with impaired drainage of the collecting system.

    Is the Percutaneous Nephrolithotomy Procedure Complicated in Patients with Anterior Caliceal Stones?
    (2013-01-01T00:00:00Z) TEPELER, Abdulkadir; BOZKURT, Omer Faruk; RESORLU, Berkan; SILAY, Mesrur Selcuk; OZYUVALI, Ekrem; Ersoz, CEVPER; Akcay, MUZAFFER; AKMAN, Tolga; ARMAGAN, Abdullah; UNSAL, Ali; ERSÖZ, CEVPER; AKÇAY, MUZAFFER
    Objectives: It was the aim of this study to evaluate and compare the outcomes of percutaneous nephrolithotomy (PNL) for the treatment of posterior and anterior caliceal stones. Patients and Methods: We performed a retrospective analysis of 86 patients with isolated caliceal stones who underwent PNL between 2011 and 2012. The patients were classified into two groups according to the localization of the stone, either in the anterior (group 1, n = 41) or posterior (group 2, n = 45) calyx, on axial plane computed tomography. Results: The mean age, male/ female ratio and stone size and location were similar in both groups. Fluoroscopy, operation time and duration of hospitalization were also similar between groups. Patients in group 1 had a greater postoperative hemoglobin drop than patients in group 2. Blood transfusion was required for 5 patients in group 1 and for 4 patients in group 2. In addition, open conversion was required for 2 patients in group 1 during the early postoperative period because of extensive bleeding. Hemodynamics were stabilized with angioembolization in 2 patients with prolonged hematuria in group 1. The overall success and complication rates were similar in both groups. Conclusion: Although the postoperative hemoglobin drop did not significantly differ between groups, hemorrhaging was more severe in patients with anterior caliceal stones than in those with posterior caliceal stones.

    Circumcision during the phallic period: does it affect the psychosexual functions in adulthood?
    The aim of this study was to elucidate whether circumcision during the phallic period (3-to 6-year old) has a negative impact on psychosexual functions in adulthood. Over a 6-month period, healthy and sexually active men between 30 and 40years without any comorbidities were involved. Participants were evaluated with detailed history, physical examination, International Index of Erectile Function (IIEF), Premature Ejaculation Diagnostic Tool (PEDT) and Beck Depression Inventory. Cases were divided into two groups according to the age at circumcision (group-1: phallic period, group-2: nonphallic period). Student-s t-test and Kruskall-Wallis were used for statistical analysis. Of the 321 participants, a total of 302 men were eligible for the study (group-1: n=135, group-2: n=167). No statistical difference was found between the mean total IIEF scores (group-1: 25.1 +/- 4.8, group-2: 25.4 +/- 4.6, P>0.05). The subdomains of IIEF; erectile function, orgasm, sexual desire, intercourse satisfaction, overall satisfaction were also found to be comparable. Additionally, the PEDT scores were similar between the two groups (group-1: 8.2 +/- 4.8, group-2: 8.7 +/- 5.4, P>0.05). Finally, Beck depression scores were also found to be comparable between the groups (group-1: 10.8 +/- 10.4, group-2: 9.8 +/- 8.9, P>0.05). Our results suggest that circumcision during the phallic period does not negatively affect the psychosexual functions in adulthood.
