Background and Objective: Acquired kidney cysts usually occur in end stage renal disease (ESRD) patients undergoing long-term hemodialysis. Increasing growth of cysts is also seen in asymptomatic patients and they can cause complications such as retroperitoneal and intrarenal bleeding, Erythrocytosis, infection of cysts and renal cell carcinoma with distant metastases. This study was designed to evaluate the prevalence of acquired kidney cysts and its related factors in hemodialysis patients.
Methods: In this descriptive-analytical study, 123 patients (mean age 55.22+13.23 years) were selected from hemodialysis patients referred to dialysis center. Patients with autosomal polycystic kidney disease, medullary sponge kidney and medullary cystic kidney disease were not included. Diagnosis of acquired kidney cysts of Patients was performed by ultrasonography.
Results: The overall prevalence of kidney cysts was 44.6%. 30 percent of diabetic patients had kidney cysts, while kidney cysts were present in 51.2% of nondiabetic patients. 32.4% of patients were received twice a week dialysis and 42.4% of patients were received three times a week dialysis had kidney cysts. Mean±SD of duration of dialysis history in patients with cystic kidneys was 22.02±22.65 months, while these measures in patients with noncystic kidneys were 22.65±14.65 months. There was a relationship between kidney cysts and the numder of hemodialysis per week (P<0.05). There was a relationship between prevalence of kidney cysts and the qulity of hemodialysis (P<0.05)
Conclusion: This study showed that there was a relationship between prevalence of kidney cysts and the qulity of hemodialysis and the numder of hemodialysis per week.

Background and Objective: Ensuring suitable access to hemodialysis, which provides high-quality dialysis over an extended period, is a significant challenge for patients with End-Stage Renal Disease (ESRD). One crucial aspect of this is maintaining the performance of hemodialysis catheters. Our study, which aimed to evaluate the one-year performance of long-term catheters in chronic hemodialysis patients in Golestan Province, is a critical step toward improving patient care in this population.
Methods: This descriptive-analytical study was conducted on 99 patients (34 men and 65 women) with ESRD who were candidates for starting or continuing dialysis with a catheter in the educational and therapeutic centers of Golestan Province, Iran during 2021-22. Transjugular catheters were placed for the patients, and after one year, variables such as age, gender, history of diabetes, history of hypertension, catheter placement site (right or left jugular), and antiplatelet medication use were evaluated concerning the performance of long-term catheters in providing adequate flow for hemodialysis.
Results: In 91 patients (91.9%), the one-year catheter performance was assessed as satisfactory. The age of 61.6% of the patients were over 60 years old. Sixty-nine patients (69.7%) had a history of hypertension, and 58 patients (58.6%) had a history of diabetes. Fifty-seven patients (57.6%) received antiplatelet medication. The catheters were placed on the right side in 82 patients (82.8%). Catheter performance in patients taking antiplatelet medication was non-significantly higher than in those not taking antiplatelet medicines.
Conclusion: The performance of long-term catheters in chronic hemodialysis patients with ESRD showed no significant correlation with age, gender, diabetes, hypertension, antiplatelet medication use, or the side of the jugular vein where the catheter was placed.
