Öğe Brucella and peritoneal dialysis related peritonitis: case report and review of literature(Dustri-Verlag Dr Karl Feistle, 2014) Koz, Suleyman; Sahin, Idris; Kayabas, Uner; Kuzucu, CigdemIsolated case reports of peritonitis due to Brucella spp. during peritoneal dialysis (PD) continue to surface in the medical literature. However, the optimal treatment regimen for these patients, in particular with regards to the fate of PD catheter, is still largely unknown. We report a case of brucella peritonitis successfully treated with intraperitoneal administration of amikacin, along with oral rifampicin and doxycycline but without catheter removal. Furthermore, we have reviewed the literature up until present day.Öğe BRUCELLOSIS INDUCED ACUTE RENAL FAILURE IN AN ELDERLY PATIENT(Gunes Kitabevi Ltd Sti, 2011) Sahin, Idris; Sahin, Huseyin Avni; Eminbeyli, Lokman; Kaba, IsmetAlthough subclinical renal involvement in brucellosis is not rare, brucellosis is a rare cause of acute renal failure. Here, we present an uncommon case of Brucella-induced acute renal failure in a previously healthy 85-year-old male farmer. He was admitted with acute renal failure and vasculitic rash on his legs. He had a 20-day history of fever, malaise, anorexia, and vomiting, and a 10-day history of vasculitic rash on his legs. He had no history of reduced urine output in this period The diagnosis was established by serological tests. Skin biopsy was concordant with leucocytoclastic vasculitis. Steroid and antibiotherapy was started. The serum creatinine began to decrease slowly after starting the specific antibiotherapy. On day 15, the renal parameters and urinalysis returned to normal. Antibiotic therapy was continued for six weeks. Brucella infection must be considered as a rare cause of acute renal failure in endemic areas.Öğe CHARACTERISTICS AND SURVIVAL RESULTS OF PERITONEAL DIALYSIS PATIENTS SUFFERING FROM COVID-19 IN TURKEY: A MULTICENTER NATIONAL STUDY(Karger, 2022) Gursu, Meltem; Ozturk, Savas; Arici, Mustafa; Sahin, Idris; Goekcay Bek, Sibel; Yilmaz, Murvet; Koyuncu, SumeyraBackground: We aimed to study the characteristics of peritoneal dialysis (PD) patients with Coronavirus disease-19 (COVID-19), determine the short-term mortality and other medical complications, and delineate the factors associated with COVID-19 outcome.Methods: In this multicenter national study, we included PD patients with confirmed COVID-19 from 27 centers. The baseline demographic, clinical, laboratory, and radiological data and outcomes at the end of the first month were recorded.Results: We enrolled 142 COVID-19 patients (median age:52 years). 58.2% of patients had mild disease at diagnosis. Lung involvement was detected in 60.8% of patients. 83 (58.4%) patients were hospitalized, 31 (21.8%) patients were admitted to intensive care unit and 24 needed mechanical ventilation. 15 (10.5%) patients were switched to hemodialysis and hemodiafiltration was performed for four (2.8%) patients. Persisting pulmonary symptoms (n=27), lower respiratory system infection (n=12), rehospitalization for any reason (n=24), malnutrition (n=6), hypervolemia (n=13), peritonitis (n=7), ultrafiltration failure (n=7) and in PD modality change (n=8) were reported in survivors. 26 patients (18.31%) died in the first month of diagnosis. The non-survivor group was older, comorbidities were more prevalent. Fever, dyspnea, cough, serious-vital disease at presentation, bilateral pulmonary involvement, and pleural effusion were more frequent among non-survivors. Age (OR:1.102; 95%CI: 1.032-1.117; p: 0.004), moderate-severe clinical disease at presentation (OR:26.825; 95%CI: 4.578-157.172; p<0.001) and baseline CRP (OR:1.008; 95%CI; 1.000-1.016; p:0.040) were associated with first-month mortality in multivariate analysis.Conclusions: Early mortality rate and medical complications are quite high in PD patients with COVID-19. Age, clinical severity of COVID-19, and baseline CRP level are the independent parameters associated with mortality.Öğe Comparison of dialysate and plasma NTproBNP in prediction of clinical outcomes of diabetic and nondiabetic peritoneal dialysis patients(Dustri-Verlag Dr Karl Feistle, 2018) Koz, Suleyman; Sahin, Idris; Kayatas, Mansur; Koz, Sema TulayBackground: Plasma level of N-terminal pro-brain natriuretic peptide (P-NTproBNP) is a useful marker in prediction of mortality in peritoneal dialysis (PD) patients. However, the predictive value of spent dialysate counterpart (D-NTproBNP) of plasma NTproBNP on mortality and dropout is not known. Materials and methods: Simultaneous P-NTproBNP and D-NTproBNP assays were performed after an overnight dwell in 44 scheduled ambulatory PD patients. Patients were followed for similar to 47 months. Deceased patients or patients who were transferred to hemodialysis were regarded as dropouts. Results: 14 patients (31.8%) dropped out at similar to 4 years (9 deaths and 5 transfers to hemodialysis). Diabetics, males, and patients with higher membrane permeability had higher dropout rates. Patients with P-and D-NTproBNP higher than median values had higher mortality and dropout rates (Kaplan-Meier test, log-rank Test p < 0.05). Odds ratios of D-NTproBNP for death and dropouts were (3.807 (0.907-15.971), p = 0.068) and (2.87 (1.009-8.138) p = 0.048), respectively; odds ratios of P-NTproBNP for death and dropouts were (4.652 (0.914-23.693), p = 0.064) and (2.67 (0.924-7.716), p = 0.07), respectively; in ROC analysis for death, AUC for P-and D-NTproBNP were 0.762 (0.578-0.946, p = 0.016) and 0.765 (0.590-0.940, p = 0.015), respectively. Exclusion of diabetic patients from the analyses resulted in significant changes in the predictive value P-and D-NTproBNP. Although death and dropout rates were still higher in nondiabetic patients with higher NTproBNP levels, the differences between groups lost statistical significance. Conclusion: Both P-NTproBNP and D-NTproBNP are significant predictors of outcomes of interest. Predictive value of NTproBNP might be different in diabetics and non-diabetic CAPD patients.Öğe Comparison of gastrointestinal symptoms and findings in renal replacement therapy modalities(Bmc, 2022) Karahan, Dogu; Sahin, IdrisObjective Chronic kidney disease (CKD) affects gastrointestinal system (GIS) and causes histological, functional and mucosal changes. There are scarce data investigating GIS symptoms and findings in patients with CKD stage III-V, receiving hemodialysis (HD) and peritoneal dialysis (PD). In this study, we aimed to evaluate the frequency of gastrointestinal symptoms and findings and compare between renal replacement therapies. Method A total of 290 patients (97 in CKD stage III-V, 92 PD, 101 HD) were included in this study. Gastrointestinal complaints, diseases, background characteristics of patients and drugs they used were questioned by interviews, forms were filled and examinations of patients were performed. Results of upper GIS endoscopy, colonoscopy, abdominal ultrasonography and tomography of patients were evaluated. Results The most common signs were dyspepsia (50%), nausea (45%) and epigastric pain (44%) among all patients, generally. Gastrointestinal disorders like gastritis (62%) and gastroesophageal reflux (39%) were frequent in patients. Prevalence of patients with weight loss was 20% in predialysis and 8% in PD and the ratio was higher in predialysis group statistically significantly (p = 0,016). The prevalence of gastritis was 70% in PD, 55% in HD and the prevalence of hemorrhoids was 24% in PD and 12% in HD. The prevalence of gastritis and hemorrhoids was higher in the PD group than in the HD group statistically significantly (p = 0.043, p = 0.028), otherwise, there wasn't a difference between the PD and predialysis groups, statistically significantly. Conclusion This study showed that; gastrointestinal symptoms and disorders were very common in CKD, besides this; while gastritis and hemorrhoids were more frequent in the PD, esophagitis and hiatal hernia were more frequent in the HD.Öğe Correlation between vitamin D status and Wechsler Adult Intelligence Scale's comprehension subtest in patient with end-stage renal diseases(Wiley-Blackwell, 2016) Karaoglan, Mehmet; Emre, Memet Hanifi; Demirtas, Yasemin; Sahin, Idris; Taskapan, Hulya[Abstract Not Available]Öğe Course of Encephalopathy in a Cirrhotic Dialysis Patient Treated Sequentially with Peritoneal and Hemodialysis(Hindawi Ltd, 2015) Koz, Suleyman; Sahin, Idris; Terzi, Zafer; Koz, Sema TulayEnd-stage kidney disease and advanced cirrhosis are sometimes seen concomitantly. There is no consensus on dialysis modality in terms of determining the optimal way of treating these patients. It has been suggested that peritoneal dialysis is a better choice for these patients, but efficacy of hemodialysis in stable cirrhotic patients has not been evaluated sufficiently. We report a case with advanced cirrhosis and end-stage kidney disease who was faced with hepatic encephalopathy episodes up on starting renal replacement therapy. The case is also interesting in that it reveals effects of hemodialysis and peritoneal dialysis on hepatic encephalopathy episodes and quality of life of the patient.Öğe The Effects of HCV Infection on Serum Lipid Profile in Hemodialysis Patients(Turk Nefroloji Diyaliz Transplantasyon Dergisi, 2010) Sahin, Idris; Eminbeyli, Lokman; Sahin, Huseyin Avni; Kaba, IsmetObjective: We aimed to investigate effects of hepatitis C virus infection on serum lipid profile in hemodialyzed patients. Method: The serum lipid profile was determined in 108 patients who had been on regular hemodialysis for at least two months. Serum total cholesterol (TC), triglyceride (TG), HDL (high density lipoprotein), VLDL (very low density lipoprotein) and LDL (low density lipoprotein) levels were compared between two groups. Results: The study included 55 HCV- negative (% 58 male) and 53 HCV-positive (% 64 male) hemodialysed patients. Mean age was 43 +/- 16 years in the HCV- negative group and 43 +/- 14 years in the HCV- positive group. There were no significant differences between the two groups with respect to age and gender. Mean duration of HD was 20 +/- 16 months in the HCV (-) group and 50 +/- 32 months in the HCV (+) group. Mean hemodialysis time was longer in HCV (+) patients than HCV (-) patients (p<0.0001). Mean serum TC (129 +/- 27 vs 148 +/- 42 mg/dL; p=0.006), TG (137 +/- 55 vs 162 +/- 64 mg/dL; p=0.032), and HDL levels (32 +/- 11 vs 36 +/- 11 mg/dL; p=0.036) were significantly lower in the HCV-ositive group than in the HCV- negative group. Mean serum LDL and VLDL levels were similar in the two groups. Although we did not find a statistical difference between serum lipid levels and ALT levels; there was a statistically significant correlation between serum AST level and TC, TG, and VLDL-c levels. Serum TC, VLDL levels were significantly higher in patients with AST >30 iu/dL than in patients with AST <30 iu/dL. Conclusion: The present study suggests that HCV infection is associated with lower TC, TG and VLDL-c levels in hemodialysed patients. An increase in serum AST levels was associated with a decrease in lipid levels.Öğe EFFECTS OF RENAL REPLACEMENT THERAPY ON FIBROMYALGIA SYNDROME IN PATIENTS WITH CHRONIC KIDNEY DISEASE(Carbone Editore, 2018) Berber, Ilhami; Sahin, Idris; Gorgel, Ahmet; Cagin, Yasir Furkan; Bag, Harika Gozukara; Berber, Nurcan KiriciIntroduction: Although musculoskeletal disorders are among the major complications of chronic kidney disease (CKD), there are scarce data to investigate fibromyalgia syndrome (FMS) in these patients. We aimed to investigate the prevalence of FMS in the patients with CKD. Material and methods: A total of 289 (119 predialysis (PD), 85 hemodialysis (HD), 85 continuous ambulatory peritoneal dialysis (CAPD)) patients were included. Diagnosis of FMS was based on American College of Rheumatology (ACR) 1990 FMS criteria. Results: Mean age was 52 +/- 16 years (range 18-89 years). One-hundred-sixty-four (56.7%) of them were male. A total of 46 patients (10 male/36 female) (15.9%) were diagnosed FMS. The prevalence of FMS was 28.8% in females and 6.1% in males. Compared to males, females had a significantly higher rate of FMS (p<0.001). The prevalence of FMS was 19.3% in PD group, 17.6% in the CAPD group, and 9.4% in the HD group. Although the frequency of FMS was lower in HD group compared to both the PD and the CAPD groups, the differences were not statistically significant (for HD vs PD, p=0.052; for HD vs CAPD, p=0.113). In PD group, hemoglobin (Hb) levels were significantly higher in patients with FMS than without FMS. Parathormone (PTH) levels were significantly lower in CAPD patients with FMS than without FMS. Although the prevalence of FMS was increased in PD and CAPD patients, this increase did not reach statistical significance. FMS was markedly more prevalent in female patients. While the Hb level was lower in the PD patients with FMS, PTH level was lower in the CAPD patients diagnosed with FMS. Conclusions: Our study demonstrated that the rate of FMS was higher in PD and CAPD patients compared to HD patients, although our results did not reach statistical significance. Among the entire demographic and laboratory parameters, female gender was found to be significant risk factor for development of FMS. Future multicenter studies which have large sample size are clearly needed to determine other factors related to development of FMS in patients with CKD.Öğe Elimination of NTproBNP in peritoneal dialysis patients Does peritoneal membrane type make a difference in plasma level and elimination of NTproBNP?(Dustri-Verlag Dr Karl Feistle, 2016) Koz, Suleyman; Sahin, Idris; Temel, Ismail; Koz, Sema T.; Terzi, ZaferBackground: Brain natriuretic peptide and its derivative peptide NTproBNP are utilized to exclude cardiac diseases, and predicting risk of mortality in dialysis patients. Our aim was to evaluate both elimination of NTproBNP through dialysate and a possible relationship between plasma and/or dialysate NTproBNP level and membrane transport status of peritoneal dialysis patients. Methods: 57 plasma (P) and dialysate (D) samples of 44 peritoneal dialysis (PD) patients were analyzed for NTproBNP. Modified peritoneal equilibration test (PET) results and other variables were obtained from the charts. Results: Median (IQR) NTproBNP concentrations (pg/mL x 1,000) in P and D were 3.3 (1 - 13) and 0.5 (0.2 - 3.6), respectively. There was a linear correlation between P-NTproBNP and D-NTproBNP (r = 0.928, p = 0.0001; regression equation was y = 0.897(*)x -0.28). Mean P/D-NTproBNP ratio was 5.5 +/- 0.5. Median P and D-NTproBNP levels by the membrane transport status were aligned as high (H) > high average (HA) > low average (LA), and the difference between H and LA was statistically significant (p < 0.001). Mean arterial pressure (MAP), residual Kt/V and dialysate/plasma ratio of crearinine (D/P Cr) were significant predictors of D-NTproBNP; whereas only MAP and residual Kt/V were significant predictors of P-NTproBNP in multiple regression analysis. Both P-and D-NTproBNP have significant and similar size of correlations with MAP, albumin, D/P Cr ratio, and Na. Conclusions: D-NTproBNP level is similar to 1/5 of P-NTproBNP, and the issue of relationship between membrane transport status and natriuretic peptide levels needs more work.Öğe Estimated Dialysate Magnesium Clearance in Peritoneal Dialysis Patients(Wiley-Blackwell, 2015) Koz, Suleyman; Sahin, Idris; Koz, Sema Tulay; Terzi, Zafer; Ataman, Engin; Akkus, Hadi[Abstract Not Available]Öğe Evaluation of hepatosteatosis and gallstone disease in patients with chronic kidney disease(Wiley, 2024) Karahan, Dogu; Sahin, IdrisIntroduction: The prevalence rates of hepatosteatosis and gallstones are increasing owing to the multifactorial causes of chronic kidney disease, and the prevalence may change with the availability of different forms of renal replacement therapy. We aimed to determine the incidence or prevalence rates of hepatosteatosis, cholelithiasis, and acute cholecystitis in patients with chronic kidney disease and compare them between renal replacement therapy modalities. Methods: A total of 270 patients (90 with chronic kidney disease stages III-V, 90 undergoing peritoneal dialysis, and 90 undergoing hemodialysis) were included and categorized into the pre-dialysis, hemodialysis, and peritoneal dialysis groups. The patients were questioned about previous gallbladder surgeries and chronic diseases. The results of abdominal ultrasonography, tomography, and magnetic resonance imaging were retrospectively evaluated with respect to the findings on the hepatobiliary system. Hepatosteatosis and cholelithiasis were diagnosed by expert radiologists on the basis of abdominal ultrasonography, tomography, and magnetic resonance imaging findings. The prevalence rates of hepatosteatosis, cholelithiasis, and other liver findings were compared between the groups. Findings: Hepatosteatosis and cholelithiasis were detected in 16.7% and 21.5% of the 270 cases, respectively. Hepatosteatosis was present in 17.8%, 25.6%, and 6.7% of patients in the pre-dialysis, hemodialysis, and peritoneal dialysis groups, respectively. The prevalence of hepatosteatosis was significantly higher in patients undergoing hemodialysis than in patients undergoing peritoneal dialysis (p = 0.002). However, no statistically significant difference was found between the peritoneal dialysis and pre-dialysis groups or between the hemodialysis and pre-dialysis groups (p >0.05). The prevalence rates of cholelithiasis were 15.6%, 28.9%, and 20.0%, in the pre-dialysis, hemodialysis, and peritoneal dialysis groups, respectively, and there were no statistically significant differences among the groups. The incidence of acute cholecystitis was significantly higher in the hemodialysis group than in the pre-dialysis group (p = 0.006). Discussion: Our study showed that the hepatobiliary system is frequently affected in chronic kidney disease and that the findings may differ depending on the renal replacement therapy modality.Öğe Evaluation of Outcomes of Peritoneal Dialysis Patients in the Post-COVID-19 Period: A National Multicenter Case-Control Study from Turkey(Karger, 2023) Ozturk, Savas; Gursu, Meltem; Arici, Mustafa; Sahin, Idris; Eren, Necmi; Yilmaz, Murvet; Koyuncu, SumeyraIntroduction: There are not enough data on the post-CO-VID-19 period for peritoneal dialysis (PD) patients affected from COVID-19. We aimed to compare the clinical and laboratory data of PD patients after COVID-19 with a control PD group. Methods: This study, supported by the Turkish Society of Nephrology, is a national, multicenter retrospective case-control study involving adult PD patients with confirmed COVID-19, using data collected from April 21, 2021, to June 11, 2021. A control PD group was also formed from each PD unit, from patients with similar characteristics but without COVID-19. Patients in the active period of COVID-19 were not included. Data at the end of the first month and within the first 90 days, as well as other outcomes, including mortality, were investigated. Results: A total of 223 patients (COVID-19 group: 113, control group: 110) from 27 centers were included. The duration of PD in both groups was similar (median [IQR]: 3.0 [1.88-6.0] years and 3.0 [2.0-5.6]), but the patient age in the COVID-19 group was lower than that in the control group (50 [IQR: 40-57] years and 56 [IQR: 46-64] years, p < 0.001). PD characteristics and baseline laboratory data were similar in both groups, except serum albumin and hemoglobin levels on day 28, which were significantly lower in the COVID-19 group. In the COVID-19 group, respiratory symptoms, rehospitalization, lower respiratory tract infection, change in PD modality, UF failure, and hypervolemia were significantly higher on the 28th day. There was no significant difference in laboratory parameters at day 90. Only 1 (0.9%) patient in the COVID-19 group died within 90 days. There was no death in the control group. Respiratory symptoms, malnutrition, and hypervolemia were significantly higher at day 90 in the COVID-19 group. Conclusion: Mortality in the first 90 days after COVID-19 in PD patients with COVID-19 was not different from the control PD group. However, some patients continued to experience significant problems, especially respiratory system symptoms, malnutrition, and hypervolemia.Öğe Features of Hemodialysis in Cirrhotic Patients: Single Center Experience(Turk Nefroloji Diyaliz Transplantasyon Dergisi, 2015) Koz, Suleyman; Sahin, Idris; Terzi, Zafer; Koz, Sema TulayOBJECTIVE: End-stage kidney disease and advanced cirrhosis are sometimes seen concomitantly. Our purpose was to compare hemodialysis (HD) sessions in critically ill cirrhotic patients from ICU versus stable cirrhotic patients from outpatient clinic, and observe endurance of both stable and acutely ill cirrhotic patients to intermittent HD. MATERIAL and METHODS: All of the Child-Pugh class B or C cirrhotic patients requiring renal replacement therapy during a period of three years were included in the study. If hypotension, arrhythmia, bleeding, or any other health problems were present during dialysis, the dialysis session was regarded as a troubled session. RESULTS: There were two groups of patients. All of the stable patients lived more than three months, whereas all patients in the ICU group died within a month. Mean ultrafiltration volume per session was 1786 +/- 210 ml in ICU and 1616 +/- 266 ml in stable patients (p>0.05). The number of the troubled sessions was 24 in ICU and 1 in stable patients (p<0.0001). Bleeding was a problem in a minority of the patients. CONCLUSION: Intermittent HD may be an acceptable choice for stable cirrhotic dialysis patients. Hypotension is a frequent complication of intermittent HD in ICU patients.Öğe Hypernatremia in the Emergency Department(Turk Nefroloji Diyaliz Transplantasyon Dergisi, 2012) Yucel, Neslihan; Sahin, Idris; Akgun, Feride Sinem; Koz, Suleyman; Berber, Ilhami; Ozdemir, Muzaffer GalipINTRODUCTION: To determine the symptoms, clinical characteristics, prevalence and outcome of patients with hypernatremia who presented at the emergency department. MATERIA LAND METHODS: We retrospectively studied patients who presented at the emergency department with hypernatremia (Na>148 meq/l) from January 2008 to December 2008. RESULTS: A total of 25.545 cases presented at the Emergency Department and hypernatremia was seen in 86 patients. The prevalence of hypernatremia was 0.34%. The mean age was 69.5 +/- 15.2 (2096, median age: 75) years and 51 of them (59%) were male. Forty percent of the patients died. There were no significant differences according to age, gender and admission Na levels. A comorbid disease were seen 99% of patients. Cerebrovascular disease(CVD), dementia/Alzheimer and hypertension were the most common co-morbid diseases (respectively, 34%, 34%, and 27%). Central neurological system disorders (such as thrombotic or hemorrhagic CVD, Alzheimer, etc.) were seen in 72% of the cases. Fifty patients had acute infection at the time of admission. Acute urinary infection, pneumonia and acute CVD were the most common acute illnesses. CONCLUSION: Hypernatremia is usually seen in the geriatric population and associated with a high mortality and morbidity rate and the majority of patients with hypernatremia have a comorbid disease. The prevalence of hypernatremia was 0.34% in our emergency department.Öğe Increased serum ferritin levels in patients with Crimean-Congo hemorrhagic fever: can it be a new severity criterion?(Elsevier Sci Ltd, 2010) Barut, Sener; Dincer, Fatma; Sahin, Idris; Ozyurt, Huseyin; Akkus, Mehmet; Erkorkmaz, UnalObjectives: Serum ferritin is one of the markers indicating hemophagocytosis that may have a role in the pathogenesis of Crimean-Congo hemorrhagic fever (CCHF). This study was designed to determine any correlation between serum ferritin and routine diagnostic laboratory markers of CCHF, and to investigate the relationship between serum ferritin levels and disease severity. Methods: Sixty-six patients with CCHF admitted to the hospital during the spring and summer months of 2006 and 2007 were included in the study. Serum ferritin levels were measured in sera obtained during the initial days of hospitalization. Data from 53 patients showing decreasing platelet counts over the first three days were used for further analysis and these patients were divided into two groups according to disease severity: group A included severe cases with lowest platelet counts <= 20 x 10(9)/l and group B included mild cases with lowest platelet counts > 20 x 10(9)/l. Results: Forty patients (60.6%) were male (mean age 43 +/- 17 years). Three patients died, thus the fatality rate was 4.5%. Fifty-one patients (77.3%) had abnormal serum ferritin levels, with levels above 500 ng/ml in 62.1%. There was a significant negative correlation between ferritin levels and concordant platelet counts (p < 0.001; r = -0.416) and ferritin was also found to be positively correlated with aspartate aminotransferase (p < 0.001; r = 0.625), alanine aminotransferase (p < 0.001; r = 0.479), and lactate dehydrogenase (p < 0.001; r = 0.684). Group A had higher ferritin levels than group B (p < 0.001). Receiver operating characteristic analysis revealed that a ferritin level of >= 1862 ng/ml had a sensitivity of 87.5% and a specificity of 83.8% in differentiating severe cases from mild ones. Conclusions: Increased serum ferritin levels may suggest a significant role of hemophagocytosis in the pathogenesis of CCHF and may be a useful marker for diagnosis, disease activity, and prognosis.

Hanifi; Demirtas, Yasemin; Sahin, Idris; Taskapan, Hulya[Abstract Not Available]Öğe Management of non-vascular complications following renal transplantation using percutaneous approach(Edizioni Luigi Pozzi, 2018) Yildirim, Ismail Okan; Berktas, Bayram; Saglik, Semih; Piskin, Turgut; Dogan, Murat; Sahin, Idris; Taskapan, HulyaOBJECTIVE: Non-vascular complications following renal transplantation can cause graft failure. In this study, we present our two-year experience with percutaneous treatment for non-vascular complications following renal transplantation. PATIENTS AND METHODS: A total of 30 patients who underwent percutaneous radiological treatment between March 2014 and July 2016 were included in the study. RESULTS: Following renal transplantation, a total of 36 percutaneous radiological procedures which includes hydronephrosis secondary to ureteral stricture (n. 15), clinical symptom producing lymphocele due to pressure (14) and creatinine elevated nondilated grafts (n. 7) after excluding other reasons of creatinine elevation, were performed. Six patients received percutaneous treatment for both ureteral stricture and lymphocele. The patients underwent balloon dilatation and double-J ureteral stent due to ureteral stricture. The mean pre- and post-procedural creatinine levels were 4.36 +/- 2.84mg/dL and 2.17 +/- 1.24 mg/dL respectively (p=0.004), indicating a significant difference. For lymphocele treatment, sclerosing agents were injected and lymphatic leakage areas were injected with percutaneous glue. The mean pre- and post-procedural creatinine values were 2.97 +/- 1.78 mg/dL and 1.75 +/- 1.18 respectively (p=0.002), indicating a significant difference. Nephrostomy catheters were placed for patients with elevated creatinine levels and non-dilated collecting system. The mean pre- and post- nephrostomy creatinine levels were 3.55 +/- 2.36 mg/dL and 2.57 +/- 1.82 mg/dL respectively (p>0.05), indicating no statistically significant difference. CONCLUSION: The results of our study suggest that percutaneous treatment is an effective method for the treatment of non-vascular complications following renal transplantation, and, therefore, should be the first option for the preservation of graft functions.
