    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.

    Objective: Renal cell carcinoma (RCC) is the 14th most common tumor in the world. In 2010, the protocol for the examination of kidney specimens with invasive carcinoma of renal tubular origin was updated. The aim of our study was to review 1-year RCC patients of our hospital according to the new protocol, classification, and staging systems with respect to their morphological and immunohistochemical features.. Methods: The medical records of 54 RCC patients between July 2012 and July 2013 were retrospectively reviewed. They were classified according to the WHO 2004 classification system and newly defined subtypes. The following variables were determined in each case: age, sex, histological subtype, stage, and Fuhrman nuclear grade. Results: In our study, 30 (55.6%) men and 24 (44.4%) women were diagnosed with RCC out of 54 patients. The median age was 56 years. In total, 21 patients had (55.2%) right-and 17 had (44.74%) left-sided tumors. Thirty-eight (70.3%) clear cell, 6 (11.1%) papillary, 7 (12.96%) chromophobe, 1 (1.85%) multilocular, 1 (1.85%) unclassified, and 1 (1.85%) tubulocystic RCC were seen. According to primary tumor, 33 (61.1%) pT1, 10 (18.51%) pT2, 9 (16.66%) pT3, and 2 (3.70%) pT4 patients were reported. Chromophobe RCCs were excluded from the Fuhrman grading (G) system; of the remaining 2 (4.17%) were G1, 30 (62.5%) were G2, 13 (27.08%) were G3, and 3 (6.25%) were G4 tumors. Conclusion: Although RCC constitutes the majority of renal tumors, different subtypes are also encountered. In our study, clear cell RCCs were the most common type of tumors consistent with the literature. The remarkable point was that chromophobe RCCs were more frequent in our study. Because of infrequency, more examples are required to distinguish newly defined subtypes.
