    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.

    (2016-01-01) Kalkan, SENAD; Ersoz, CEVPER; ARMAGAN, Abdullah; TASCI, Ali Ihsan; SILAY, Mesrur Selcuk; KALKAN, SENAD; ERSÖZ, CEVPER
    Objective: There are 2 critical steps of stent placement during laparoscopic pyeloplasty (LP) in children. Introduction to the ureteropelvic junction and passing through the ureterovesical junction. We aimed at overcoming those 2 steps by creating a modified technique. Methods: Consecutive 27 children undergoing transperitoneal laparoscopic dismembered pyeloplasty by a single surgeon were prospectively enrolled into this study. The modifications of our technique are using an Amplatz dilator and a closed tip stent. Results: The mean age of the children was 6.7 (range 4 months-17 years). The mean time of stent insertion was 2.7 +/- 2.0 (2-6) min and the operative time was 128.3 +/- 17.6 (90-180) min. The mean number of days of hospital stay was 2.0 +/- 0.4 (1-3). After a mean follow-up period of 20.3 +/- 4.2 (14-30) months, no operative failure was detected. Conclusion: Our modified technique is a completion of the current armamentarium for stent placement during LP in infants and children. (C) 2016 S. Karger AG, Basel
