Item Transpaeritoneal Laparoscopic Simple Nephrectomy: A Single Center Experience(2014) Cicek, Tufan; Sen, Erhan; Gonen, Murat; Gonulalan, Umut; Kosan, Murat; Ozturk, Bulent; 0000-0003-1944-1722; AAJ-8576-2021; AAA-7140-2021Purpose: In this study, we planned to evaluate the efficacy and perioperative outcomes of transperitoneal laparoscopic simple nephrectomy at Baskent University Konya Application and Research Center. Material and Methods: The demographic and perioperative data of patients who underwent transperitoneal laparoscopic simple nephrectomy at Baskent University Konya Application and Research Center Urology clinic between February 2005 and November 2013 were analyzed retrospectively. Operative time, perioperative laboratory results, the durations of hozpitalization and follow-up, perioperative complications and demographic characteristics of each patient were recorded. Results: Overall, 58 patients were included. 27 patients were male (46%) and 31 patients were female (54%). The mean age was 45.3 +/- 17.12 (6-79). The mean operative time was 104.4 +/- 36.5 (40-185) minutes. The mean hospitalization duration was 2.7 +/- 0.7 (2-5) days. The mean preoperative and postoperative hemoglobin levels were 13.7 +/- 1.74 and 12.4 +/- 1.73 mg/dl, respectively. Postoperative hemoglobin levels were statistically significatly lower than preoperative hemoglobin levels (p<0.001). 4 patients (%6.9) needed blood transfusion. 5 patients had grade I, 4 patients had grade II and 2 patients had grade III complications according to modified Clavien classification system. Conclusion: Transperitoneal laparoscopic simple nephrectomy seems to be a safe and efficacious treatment option as having low complication rates.Item Laparoscopic Transperitoneal Adrenalectomy: Experience with the First 10 Patients(2014) Cicek, Tufan; Karagulle, Erdal; Turk, Emin; Demir, Canan Cicek; Kosan, Murat; 0000-0003-4766-3373; AAJ-5609-2021; JBF-7113-2023; AAK-4857-2021Purpose: In this study we aimed to assess the outcomes and complications of laparoscopic transperitoneal adrenalectomy operation performed in our clinic Materials and Methods: Medical records of patients operated with laparoscopic transperitoneal adrenalectomy between February 2007 and November 2013 at Baskent University Konya Application and Research Center Urology Clinic are examined retrospectively. The demographic characteristics, preoperative and postoperative laboratory results, operation times, complications, and duration of hospital stay and follow- up were recorded. Results: A total of 10 patients underwent laparoscopic transperitoneal adrenalectomy. Seven of these were male and 3 were female. The mean age was 48 +/- 17.4 (27-71) years. The operation time was 104.4 +/- 36.5 (40-185) on average and the mean amount of blood loss was 43.5 +/- 121.2 ml. The average mass size was 41.6 +/- 23.8 (15-90) mm. The mean duration of hospital stay was 3.8 +/- 1.3 (2-6) days. The patients were followed for an average of 45.8 +/- 28.7 (4-85) months. The operation was turned to open technique in two patients. Mean preoperative and postoperative hemoglobin levels of the patients were 13.38 +/- 1.91 and 11.6 +/- 1.7 mg/dl, respectively. Postoperative hemoglobin level was on average lower than the preoperative level (p< 0.001). One patient required blood transfusion. Conclusion: We suggest that the complication rate of laparoscopic adrenalectomy would be lowered by selecting appropriate patients, more detailed assessment of adrenal functions, and increased surgical experience. Laparoscopic transperitoneal adrenalectomy is regarded as a safe and efficient treatment method.Item Renal Stone Composition Does not Affect The Outcome of Percutaneous Nephrolithotomy in Children(2018) Kaygisiz, Onur; Turegun, Fethi Ahmet; Satar, Nihat; Ozen, Ender; Toksoz, Serdar; Dogan, Hasan Serkan; Piskin, Mehmet Mesut; Izol, Volkan; Sarikaya, Saban; Kilicarslan, Hakan; Cicek, Tufan; Ozturk, Ahmet; Tekgul, Serdar; Onal, Bulent; 29761226Purpose We sought to investigate the association between renal stone composition and percutaneous nephrolithotomy outcomes in pediatric patients and define the characterization of the stone composition. Methods The data of 1157 children who underwent percutaneous nephrolithotomy between 1991 and 2012 were retrieved from the multicenter database of the Turkish Pediatric Urology Society. The study population comprised 359 children (160 girls, 199 boys) with stone analyses. Patients were divided into five groups according to the stone composition [group 1: calcium oxalate; group 2: calcium phosphate; group 3: infection stones (magnesium ammonium phosphate, ammonium urate); group 4: cystine; group 5: uric acid, xanthine stones]. Results Patient characteristics, perioperative, postoperative, and stone characteristics were compared considering the stone composition. There were no significant differences between the groups concerning age, sex, side involved, preoperative hematocrit levels, and solitary renal unit. Patients with cystine stones were more likely to have a history of stone treatment. Groups 2 and 5 had mostly solitary stones. However, group 3 had staghorn stone more often, and group 4 frequently had multiple stones. Overall stone-free rate (79.4%) was similar among the groups. Although stone composition was related to blood transfusion and prolonged operative and fluoroscopy screening times on univariate analysis, it was not a significant predictor of them on multivariate analysis. Conclusions Stone composition was not a predictor of outcomes of pediatric percutaneous nephrolithotomy. However, cystine and infection stones, which are larger and filled multiple calyxes due to the nature of stone forming, were more challenging cases that need multiple tracts.
