    Objective: To compare the results of transperitoneal laparoscopic nephrectomy in patients with atrophic and hydronephrotic kidneys. Material and methods: Clinical data were collected from 35 patients who had undergone laparoscopic nephrectomies for atrophic or hydronephrotic non-functioning kidneys between January 2010 and March 2014. Comparative analysis was carried out between the two groups examining demographic characteristics, imaging modalities, etiology, operative times, port numbers, conversion to open surgery, complications, pre- and post-operative hemoglobin and creatinine values, transfussion rates and length of hospital stays. Results: Laparoscopic nephrectomy was performed for atrophic kidneys in 20 (57%) patients and for hydronephrotic kidneys in 15 (42%) patients. In the atrophic group, 3 patients (15%) required transfusion because of bleeding but none of the patients required conversion to open surgery. In the hydronephrotic group one patient (6.6%) required transfusion and conversion to open surgery because of bleeding. Both of the groups were similar in terms of postoperative hospital stay but compared to the atrophic kidneys, hydronephrotic ones were associated with a longer total operative times (90.1 min vs. 73.6 min, p=0.03). Any serious complication (except for bleeding) and mortality were not encountered in both groups. Conclusion: Laparoscopic nephrectomy is a safe and effective minimally invasive technique that can be used in atrophic and hydronephrotic non-functioning kidneys.

    The Role of Microperc in the Treatment of Symptomatic Lower Pole Renal Calculi
    (2013-01-01T00:00:00Z) TEPELER, Abdulkadir; ARMAGAN, Abdullah; Sancaktutar, Ahmet Ali; SILAY, Mesrur Selcuk; Penbegul, Necmettin; AKMAN, Tolga; Hatipoglu, Namik Kemal; Ersoz, CEVPER; ERDEM, Mehmet Remzi; Akcay, MUZAFFER; ERSÖZ, CEVPER; AKÇAY, MUZAFFER
    Background and Purpose: The treatment of symptomatic lower pole (LP) calculi poses a challenge because of lower clearance rates. We present our experience with microperc in the treatment of LP renal calculi.

    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.
