Publication Metadata only 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, MUZAFFERBackground 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.Publication Open Access The relationship of neutrophil to lymphocyte ratio with testicular cancer(2020-01-01) İlktaç, Abdullah; Akbulut, Habib; Akçay, Muzaffer; Ersöz, Cevper; Doğan, Bayram; İLKTAÇ, ABDULLAH; DOĞAN, BAYRAM; ERSÖZ, CEVPER; AKÇAY, MUZAFFER; AKBULUT, HABİBPurpose: 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.Publication Metadata only Is lymph node dissection necessary for staging while undergoing nephrectomy in patients with renal cell carcinoma?(2020-08-06T00:00:00Z) Ersöz, Cevper; Demir, Tarık; Aliyev, Altay; Beşiroğlu, Mehmet; Araz, Murat; Köstek, Osman; Sakin, Abdullah; Shbair, Abdallah T M; Çoban, Ganime; Şeker, Mesut; Türk, HACI MEHMET; ERSÖZ, CEVPER; TÜRK, HACI MEHMETPublication Open Access Mesh related vesico-peritoneal fistula presenting with urinary ascites: A case report(2019-03-01T00:00:00Z) İLKTAÇ, ABDULLAH; ERSÖZ, CEVPER; DOĞAN, BAYRAM; KALKAN, Senad; İLKTAÇ, ABDULLAH; ERSÖZ, CEVPER; DOĞAN, BAYRAM; KALKAN, SENADVesicoperitoneal fistula is a very rare entity of epithelialized communication between peritoneal cavity and bladder.1 It results in accumulation of urine in peritoneal cavity and causes elevated urea and creatinine levels mimicking acute renal failure. Incisional hernia is common complication of abdominal surgery and often repaired with non-absorbable mesh.2 Using dual mesh can reduce mesh related complications but migration to adjacent organs can still happen and cause severe complications. Here we present a case of mesh related vesico-peritoneal fistula presenting with urinary ascites 2 years after incisional hernia repair.Publication Metadata only Histopathological Features of Paratesticular Solid Tumors: 5 Years Experience(2020-05-01T00:00:00Z) Çoban, Ganime; Yıldız, Pelin; Kıran, Tuğçe; Ersöz, Cevper; ÇOBAN, GANİME; YILDIZ, PELİN; KIRAN, TUĞÇE; ERSÖZ, CEVPERPublication Metadata only The association of GLUT-1, Galectin 3 and Claudin 1 staining with the type of renal tumors(2019-01-01T00:00:00Z) ÇOBAN, GANİME; TURNA, SEVAL; YILDIZ, PELİN; ÜNVER, NURCAN; BÜYÜKPINARBAŞILI, NUR; ERSÖZ, CEVPER; GÜCİN, ZÜHAL; TURNA, SEVAL; YILDIZ, PELİN; ERSÖZ, CEVPER; GÜCİN, ZÜHALPublication Open Access Comparison of Scoring Systems in Predicting Success of Percutaneous Nephrolithotomy(2019-01-01T00:00:00Z) AKÇAY, MUZAFFER; Tosun, Muhammed; GEVHER, FATİH; KALKAN, Senad; ERSÖZ, CEVPER; Kayali, Yunus; Tepeler, Abdulkadir; AKÇAY, MUZAFFER; TOSUN, MUHAMMED; GEVHER, FATİH; KALKAN, SENAD; ERSÖZ, CEVPER; KAYALI, YUNUSBackground: 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.

Remzi; TOPAKTAS, Ramazan; Ersoz, CEVPER; ERSÖZ, CEVPERPublication Metadata only 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, SENADThe 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.Publication Unknown IS PERCUTANEOUS NEPHROLITHOTOMY PROCEDURE COMPLICATED IN PATIENTS WITH ANTERIOR CALICEAL STONES?(2012-09-01T00:00:00Z) Tepeler, Abdulkadir; Resorlu, Berkan; Ozyuvali, Ekrem; Akman, Tolga; ERSÖZ, CEVPER; AKÇAY, MUZAFFER; Silay, Mesrur Selcuk; Armagan, Abdullah; Unsal, Ali; ERSÖZ, CEVPER; AKÇAY, MUZAFFER
