Objective To investigate the prevalence of restless legs syndrome (RLS) in peritoneal dialysis patients and analyze the related risk factors.Methods This study was a cross-sectional study.The patients receiving maintenance peritoneal dialysis from January 2017 to December 2017 in the Peritoneal Dialysis Center of the Second Hospital Affiliated to Soochow University were selected as the study subjects.RLS was screened for peritoneal dialysis patients by epidemiological field investigation based on the RLS diagnostic criteria of the International Restless Leg Syndrome Research Group in 2014.Clinical data and laboratory examinations of selected patients were collected and the differences of clinical indicators between RLS and non-RLS patients were compared.The risk factors related to RLS were analyzed by logistic regression.Results Seventy-six cases of RLS were screened out from 396 PD patients.The prevalence of RLS was 19.2％.Compared with non-RLS group,RLS group patients had longer dialysis age,less 24 hours urine volume,and elevated blood intact Parathormone (iPTH) and alkaline phosphatase (AKP) (all P ＜ 0.05).There was no significant difference in primary disease ratio,sex,age,body mass index,blood pressure,hemoglobin,creatinine,urea nitrogen,uric acid,ferritin,serum iron,transferrin saturation,blood calcium,blood phosphorus,total cholesterol,triglyceride,low density lipoprotein,high density lipoprotein,eGFR,Kt/V,Ccr between RLS and non-RLS group patients (all P ＞ 0.05).Multivariate logistic regression analysis showed that long dialysis age (OR=1.010,95％CI 1.001-1.018,P=0.022) and high blood AKP (OR=1.005,95％CI 1.001-1.010,P=0.021) were independent risk factors for RLS in peritoneal dialysis patients (both P ＜ 0.05).Conclusions The prevalence of RLS is high in peritoneal dialysis patients.Long dialysis age and high blood AKP are independent risk factors for RLS.

To compare the efficacy, safety and economic cost of endoscopic ultrasound (EUS)-guided puncture sclerotherapy and laparoscopic decapitation decompression for the renal cysts in the upper pole, data of patients with renal cysts in the upper pole who received EUS-guided puncture sclerotherapy (the EUS group, n=9) or laparoscopic decapitation decompression (the laparoscopy group, n=16) in the Second Affiliated Hospital of Soochow University from January 2021 to August 2022 were analyzed retrospectively. The effective rate, operation time, intraoperative blood loss, incidence of complications, hospital stay and treatment cost of the EUS group and the laparoscopy group were compared. Results showed that the effective rate was comparable in the EUS group and laparoscopy group (9/9 VS 14/16, P=0.520). The operation time was shorter (29.8±4.8 min VS 70.1±11.1 min, t=10.207, P<0.001), intraoperative blood loss less (0 mL VS 26.1±5.9 mL, t=13.089, P<0.001), postoperative hospital stay shorter (3.5±0.7 days VS 5.4±2.0 days, t=2.663, P=0.014), and total cost lower (10 547.85±2 388.19 yuan VS 15 316.09±5 352.45 yuan, t=2.517, P=0.019) in the EUS group compared with those in the laparoscopy group. There was no significant difference in the total hospital stay (8.1±2.0 days VS 9.3±3.1 days, t=1.019, P=0.319) or operation cost (3 946.79±490.82 yuan VS 3 860.18±857.42 yuan, t=-0.277, P=0.784) between the EUS group and laparoscopy group. There was 1 case of puncture bleeding, 1 case of hematuria, and 1 case of lumbago in the laparoscopy group, while no complication occurred in the EUS group. In conclusion, it is preliminarily believed that EUS-guided puncture sclerotherapy for renal cysts in the upper pole has similar clinical effects with higher safety, shorter postoperative hospital stay and lower total hospitalization cost compared with those of laparoscopic decapitation decompression, which is worth of clinical promotion.

Objective: To discuss the neuroimaging characteristics of transcranial ultrasound in end-stage renal disease (ESRD) with restless legs syndrome. Methods: Transcranial sonography (TCS) was performed in ESRD with restless legs syndrome (RLS+ group, n=41), ESRD without restless legs syndrome (RLS- group, n=57) and control group (n=47), who were enrolled in the Second Affiliated Hospital of Soochow University from January 2017 to December 2018. The differences of the neuroimaging characteristics of TCS in substantia nigra (SN), brainstem raphe (BR) and red nucleus(RN) among the three groups were analyzed. Results: The rate of SN hypoechogenicity was significantly higher in RLS+ group (36.6%, 15/41) than that in RLS- group (19.3%, 11/57) and control group(8.5%, 4/47) (χ²=10.6, P<0.05). The rate of abnormal BR echogenicity was significantly higher in RLS+ group (34.1%, 14/41) and RLS- group (29.8%, 17/57) than that in control group(10.6%, 5/47) (χ²=7.7, P<0.05). The rate of RN hyperechogenicity was significantly higher in RLS+ group (51.2%, 21/41) than that in RLS- group (21.1%, 12/57) and control group (10.6%, 5/47) (χ²=19.8, P<0.05). Between RLS+ and RLS- groups, when SN, BR and RN were all of positive performance, the accuracy of diagnosing RLS+ reached 70% (7/10). Conclusions The echogenicity changes of SN, BR and RN on TCS could provide valuable neuroimaging information for the clinical diagnosis and treatment of ESRD with restless legs syndrome.
