Background: Percutaneous nephrolithotomy (PCNL) procedures in the United States typically cost between 9000 to 16000 USD. In developing countries like Iran, healthcare performance is hindered by issues such as high bed occupancy rates. Therefore, performing PCNL in an outpatient setting could significantly reduce surgical costs and improve healthcare outcomes by reducing bed occupancy and associated complications. Objectives: This study aimed to explore the feasibility of same-day discharge for selected PCNL patients. Methods: Out of 142 patients, 32 were discharged within 12 hours post-operation (Study Group), while 32 randomly selected patients from the remaining 110 served as the control group. Same-day discharge criteria included stable vital signs, tolerance to oral intake, appropriate mobility, and normal laboratory results. Exclusion criteria encompassed the need for red blood cell transfusion, hemoglobin drops exceeding 2 mg/dL, and abnormal post-operative laboratory findings. Results: Patient characteristics and medical histories did not significantly differ between the study and control groups. Additionally, stone laterality (P-value = 0.606), location (P-value = 0.731), size (P-value = 0.334), and density (P-value = 0.065) showed no significant differences between the two groups. The post-surgical observation period in the study group (mean: 7.88 hours) was significantly shorter than that in the control group (mean: 62 hours) (P-value < 0.001). The mean hemoglobin level change was 1.48 mg/dL (SD: ± 1.02) in the study group and 1.31 mg/dL (SD: ± 0.91) in the control group. Similarly, the change in creatinine levels was 0.13 ± 0.04 in the study group and 0.23 ± 0.03 in the control group. Conclusions: This study demonstrates that outpatient PCNL procedures are feasible without increasing perioperative complications. However, careful patient selection based on strict criteria is crucial for successful implementation.
背景:在美国,经皮肾镜取石术(PCNL)的费用通常在 9000 到 16000 美元之间。在伊朗等发展中国家,高病床占用率等问题阻碍了医疗服务的改善。因此,在门诊环境下进行 PCNL 可显著降低手术成本,并通过减少病床占用率和相关并发症来改善医疗效果。研究目的本研究旨在探讨 PCNL 患者当天出院的可行性。方法:在 142 名患者中,32 名患者在术后 12 小时内出院(研究组),其余 110 名患者中随机抽取 32 名患者作为对照组。当天出院的标准包括生命体征稳定、能耐受口服摄入、活动自如、化验结果正常。排除标准包括需要输注红细胞、血红蛋白下降超过 2 毫克/分升以及术后化验结果异常。结果研究组和对照组的患者特征和病史无明显差异。此外,两组患者的结石侧位(P 值 = 0.606)、位置(P 值 = 0.731)、大小(P 值 = 0.334)和密度(P 值 = 0.065)均无明显差异。研究组的术后观察时间(平均:7.88 小时)明显短于对照组(平均:62 小时)(P 值 < 0.001)。研究组的平均血红蛋白水平变化为 1.48 mg/dL (SD: ± 1.02),对照组为 1.31 mg/dL (SD: ± 0.91)。同样,研究组的肌酐水平变化为 0.13 ± 0.04,对照组为 0.23 ± 0.03。结论这项研究表明,门诊 PCNL 手术是可行的,不会增加围手术期并发症。然而,根据严格的标准谨慎选择患者是成功实施手术的关键。

Background: Urinary stone disease (USD) refers to the presence of stones or salt crystals within the urinary tract, with calcium stones accounting for approximately 80% of cases. Increased urinary calcium and phosphorus excretion predispose individuals to urinary stones, with hypercalciuria being the most significant risk factor. Vitamin D plays a pivotal role in modifying urine calcium and phosphorus excretion, and it enhances calcium and phosphorus reabsorption in the kidneys. Urinary stone disease is a recognized risk factor for chronic kidney disease (CKD) and may also lead to life-threatening complications such as perinephric abscesses, urosepsis, and urinary tract malignancies. The role of serum vitamin D and its effects on serum calcium and phosphorus in urinary stone formation have been subjects of controversy. Objectives: This study aims to evaluate the associations between serum calcium, phosphorus, and vitamin D levels and urinary stones. Methods: This retrospective study involved two groups of 90 patients, one with urinary stones and the other without. Demographic and biochemical data, including serum calcium, phosphorus, and 25-(OH) vitamin D levels, were recorded for all patients. Patients were categorized into four groups based on their serum vitamin D levels: Excess, sufficient, insufficient, and deficient. The presence and characteristics of urinary stones were assessed using non-contrast CT scans. Results: The mean age of the patients was 54.62 ± 15.46 years. Laboratory investigations revealed mean serum calcium, phosphorus, and vitamin D levels of 9.56 ± 0.65 mg/dL, 3.53 ± 0.79 mg/dL, and 25.05 ± 12.96 ng/mL, respectively. This study demonstrated a significant correlation between serum calcium levels and the maximum diameter of urinary stones (correlation = 0.313, P-value = 0.005). No other significant associations were found between serum calcium, serum phosphorus, and serum vitamin D levels and the number of kidney stones, stone laterality, and type of kidney stone. There was also no significant difference between the two groups. Conclusions: In conclusion, the role of serum calcium, phosphorus, and 25-(OH) vitamin D levels in urinary stone formation remains controversial. This study suggests that there is no significant association between serum calcium, phosphorus, or 25-(OH) vitamin D and urinary stones, except for a positive association between serum calcium and the diameter of the stone.
背景:尿路结石病(USD)是指尿路中出现结石或盐类结晶,其中钙结石约占 80%。尿钙和磷排泄量增加易导致尿路结石,其中高钙尿症是最重要的风险因素。维生素 D 在改变尿钙和磷的排泄方面起着关键作用,它还能促进肾脏对钙和磷的重吸收。尿石症是公认的慢性肾脏病(CKD)的危险因素,还可能导致肾周脓肿、尿毒症和尿路恶性肿瘤等危及生命的并发症。血清维生素 D 及其对血清钙和磷的影响在泌尿系结石形成中的作用一直存在争议。研究目的本研究旨在评估血清钙、磷和维生素 D 水平与泌尿系结石之间的关系。研究方法:这项回顾性研究涉及两组共 90 名患者,一组患有泌尿系结石,另一组没有。研究记录了所有患者的人口统计学和生化数据,包括血清钙、磷和 25-(OH) 维生素 D 水平。根据血清维生素 D 水平将患者分为四组:过量组、充足组、不足组和缺乏组。使用非对比 CT 扫描评估尿路结石的存在和特征。结果显示患者的平均年龄为(54.62 ± 15.46)岁。实验室检查显示平均血清钙、磷和维生素 D 水平分别为 9.56 ± 0.65 mg/dL、3.53 ± 0.79 mg/dL 和 25.05 ± 12.96 ng/mL。这项研究表明,血清钙水平与尿路结石的最大直径之间存在明显的相关性(相关性 = 0.313,P 值 = 0.005)。在血清钙、血清磷和血清维生素 D 水平与肾结石数量、结石侧位和肾结石类型之间没有发现其他明显的相关性。两组之间也无明显差异。结论总之,血清钙、磷和 25-(OH) 维生素 D 水平在泌尿系结石形成中的作用仍存在争议。本研究表明,除了血清钙与结石直径呈正相关外,血清钙、磷或 25-(OH) 维生素 D 与泌尿系结石之间并无明显关联。

Background: Healthcare-associated urinary tract infections (HAUTIs) are the most prevalent healthcare-associated infection worldwide. They can lead to major problems in hospitalized patients, including the increase in the length of the hospital stay, the cost of the hospitalization, and the inappropriate administration of antibiotics. Objectives: We aim to investigate the prevalence and antibacterial sensitivity of various bacteria that cause HAUTIs. Methods: This cross-sectional study was conducted in three referral hospitals in Isfahan, Iran. Urine specimens were taken from urinary catheters of the patients with a suspected diagnosis of HA-UTI. Bacteria were identified by conventional methods, and antimicrobial sensitivity testing was performed by disk diffusion and E-test methods according to standard guidelines. Data was extracted from WHONET software, and further statistical analysis was performed by SPSS v.21. Results: Among 283 HAUTIs, Escherichia coli was the most prevalent pathogen (33.2%), followed by Enterococcus spp. (25.9%), Klebsiella pneumonia (16.6%), Pseudomonas aeruginosa (8.8%), and Acinetobacter baumannii (8.8%). Escherichia coli was more common in females. The most active antibiotics against Gram-negative isolates were nitrofurantoin (69.8%), carbapenems (69.7%), and aminoglycosides (68.3%), and the most effective antibiotics against Gram-positive isolates were linezolid (100%) and nitrofurantoin (74.5%). Conclusions: This study showed that nitrofurantoin, carbapenems, and aminoglycosides are the most effective antibiotics against Gram-negative causes of HAUTIs. Also, linezolid and nitrofurantoin demonstrated significant activity against Gram-positive isolates. As a result, for the empiric treatment of nosocomial UTI in the area under study, judicious use of the mentioned antibiotics is recommended.
背景:卫生保健相关性尿路感染(HAUTIs)是世界范围内最普遍的卫生保健相关感染。它们会给住院病人带来重大问题,包括住院时间的延长、住院费用的增加以及抗生素的不当使用。目的:了解引起HAUTIs的各种细菌的流行情况和抗菌敏感性。方法:本横断面研究在伊朗伊斯法罕的三家转诊医院进行。从怀疑诊断为HA-UTI的患者的导尿管中取尿标本。采用常规方法进行细菌鉴定,采用纸片扩散法和e -试验法进行药敏试验。数据由WHONET软件提取,采用SPSS v.21进行进一步统计分析。结果:283例HAUTIs中,以大肠埃希菌为主(33.2%),其次为肠球菌(25.9%)、肺炎克雷伯菌(16.6%)、铜绿假单胞菌(8.8%)和鲍曼不动杆菌(8.8%)。大肠杆菌在女性中更为常见。对革兰氏阴性菌株最有效的抗生素是呋喃妥因(69.8%)、碳青霉烯类(69.7%)和氨基糖苷类(68.3%),对革兰氏阳性菌株最有效的抗生素是利奈唑胺(100%)和呋喃妥因(74.5%)。结论:本研究表明呋喃妥因、碳青霉烯类和氨基糖苷类是治疗革兰氏阴性致HAUTIs最有效的抗生素。此外,利奈唑胺和呋喃妥英对革兰氏阳性菌株有显著的抑制作用。因此,对于经验性治疗院内尿路感染的研究地区,建议审慎使用上述抗生素。

Background: A complete adherence to treatment is essential for patients undergoing hemodialysis treatment. This health behavior is the product of various overlapping variables that may change over time. Objectives: This study aimed to investigate treatment adherence based on general health and demographic characteristics among hemodialysis patients. Methods: This was a descriptive-correlation research conducted based on structural equation modeling. The population included all patients with chronic kidney disease in Tehran, Iran, of whom 200 patients undergoing hemodialysis admitted to 2 medical centers from September to March 2022 were selected by convenience sampling. The data were collected using the General Health Questionnaire (GHQ) and End-Stage Renal Disease Adherence Questionnaire (ESRD-AQ). The data were analyzed using correlation analysis and path analysis in SPSS v. 19 and SmartPLS v. 3. Results: The results showed the direct and significant effect of general health (P = 0.001) and age (P = 0.017) on treatment adherence. However, sex, marital status, level of education, and duration of dialysis treatment had no significant effect on treatment adherence. Conclusions: Considering the power of general health and age in predicting treatment adherence, these two variables can be included in training, clinical, and psychological interventions.

Introduction: Renal artery stenosis (RAS) is defined by a decrease in the internal diameter of one or both of the renal arteries. This can lead to renal insufficiency. RAS mostly occurs due to atherosclerosis; however, other conditions can cause this complication. Case Presentation: We present a 66-year-old man who was initially presented with abrupt bilateral lower limbs and scrotal edema in Shahid Beheshti Hospital of Qom. The patient had been regularly visiting the nephrology clinic for mild CKD. Due to the increased levels of creatinine (Cr) and urea in serum, he underwent angiography with suspicion of RAS, and 99% stenosis was confirmed in the left renal artery. Immediately after the diagnosis, we subjected the patient to angioplasty. After removing the arterial stenosis, the patient passed 8 liters of urine during one day, and his symptoms, including generalized edema, weight gain, and dyspnea, were improved gradually. The patient was discharged after 8 days of hospitalization with dramatically improved kidney function and relatively good general conditions. Conclusions: This patient had an uncommon presentation for a unilateral RAS and significant narrowing in the healthy renal artery. Angioplasty and stenting yielded a satisfactory result as a definite and effective treatment, and the patient enjoyed a relatively normal life with preserved kidney function during 4 years of follow-up.
导言:肾动脉狭窄(RAS)是指一条或两条肾动脉内径减小。这会导致肾功能不全。RAS主要发生于动脉粥样硬化;然而,其他情况也可能导致这种并发症。病例介绍:我们报告了一位66岁的男性,他最初在库姆的Shahid Beheshti医院出现了突然的双侧下肢和阴囊水肿。该患者因轻度CKD而定期去肾脏病诊所就诊。由于血清肌酐(Cr)和尿素水平升高,怀疑RAS行血管造影,99%狭窄位于左肾动脉。诊断后,我们立即对患者进行血管成形术。切除动脉狭窄后,患者1天排尿8升,全身性水肿、体重增加、呼吸困难等症状逐渐好转。患者住院8天后出院,肾功能明显改善,一般情况较好。结论:该患者具有罕见的单侧RAS和健康肾动脉明显狭窄的表现。血管成形术和支架置入术是一种明确有效的治疗方法,疗效满意,随访4年,患者生活相对正常,肾功能得以保留。

Background: Colistin is a drug of choice against multidrug-resistance (MDR) bacteria. The most important side effect of colistin is nephrotoxicity, observed in 20 - 54% of patients. According to the studies that examined its antioxidant effect, it can reduce the kidney toxicity of various drugs, including colistin. Objectives: This study aimed to investigate melatonin's effect on reducing colistin-induced kidney toxicity to use this drug with fewer complications. Methods: This double-blind, randomized clinical trials with two groups involved 56 critically ill adults infected by MDR bacteria. The intervention group received 3 mg of oral melatonin simultaneously with intravenous colistin, which continued until the end of the treatment. The control group received placebo orally with IV colistin. We measured urine volume, blood creatinine, and BUN daily and determined the patients with renal failure using the KDIGO guideline. STATA software analyzed data with a P-value of less than 0.05 as the significance level. Results: Data obtained from recipients were analyzed for age (P-value = 0.357), gender (P-value = 0.945), weight (P-value = 0.438), APACHE score (P-value = 0.162). We did not observe significant difference in AKI criteria between the two groups. Compared to the control group, melatonin did not decrease blood creatinine (P-value = 0.110) and BUN (P-value = 0.567) and, made no change of urinary volume (P-value = 0.913). There was no decrease in kidney failure in the intervention group compared to the control group. As a result, we did not find a significant difference in outcome of the two groups. Conclusions: We did not reveal any significant difference in the AKI criteria including blood creatinine, BUN, and daily urine volume with the addition of melatonin in participants receiving colistin; However, no complication was observed in the intervention group who received melatonin.
背景:粘菌素是抗多药耐药(MDR)细菌的首选药物。粘菌素最重要的副作用是肾毒性,在20 - 54%的患者中观察到。根据检验其抗氧化作用的研究,它可以减少包括粘菌素在内的各种药物的肾毒性。目的:本研究旨在探讨褪黑素对减少粘菌素引起的肾毒性的作用,以减少该药物的并发症。方法:该双盲、随机临床试验分为两组,涉及56例MDR细菌感染的危重患者。干预组在静脉注射粘菌素的同时口服褪黑素3mg,直至治疗结束。对照组患者口服安慰剂并静脉注射粘菌素。我们每天测量尿量、血肌酐和BUN,并使用KDIGO指南确定肾功能衰竭患者。STATA软件以p值小于0.05为显著性水平分析数据。结果:对受者的年龄(p值= 0.357)、性别(p值= 0.945)、体重(p值= 0.438)、APACHE评分(p值= 0.162)进行分析。我们没有观察到两组之间AKI标准的显著差异。与对照组相比,褪黑素没有降低血肌酐(p值= 0.110)和BUN (p值= 0.567),没有改变尿量(p值= 0.913)。与对照组相比,干预组的肾衰竭发生率没有下降。因此,我们没有发现两组的结果有显著差异。结论:我们没有发现在接受粘菌素治疗的受试者中,加入褪黑素后AKI标准(包括血肌酐、BUN和日尿量)有任何显著差异;然而,在接受褪黑素治疗的干预组中,没有观察到并发症。

Background: Sperm cryopreservation can reduce the quality of sperm. Antioxidants can improve sperm parameters by decreasing oxidative stress. Objectives: This study was performed to determine the effect of supplementing sperm freezing media with cysteamine on the quality of sperm after freezing. Methods: This descriptive-analytical research was conducted at Omolbanin Center for Infertility Treatment in Dezful, Iran, in 2022. The samples included 60 men with normosperm based on the World Health Organization standards. Each sample was divided into three parts: 1. fresh semen group, 2. semen frozen with 10 mmol cysteamine supplementation, and 3. semen frozen without cysteamine supplementation. Viability, motility, morphology, total antioxidant capacity (TAC), and malondialdehyde (MDA) levels were evaluated. The results were described using SPSS version 22, and the significance level was considered P ≤ 0.05. Results: The mean of progressive motility was significantly higher in the fresh semen group (48.3 ± 4.74) compared to the two other groups. The mean progressive motility was significantly lower in the group without cysteamine supplementation (24.4 ± 3.38) than in the group with cysteamine supplementation (35.3 ± 4.9). Moreover, TAC was significantly higher in the group with cysteamine supplementation (816.6 ± 4.36) than in the other groups. We found that the MDA level was significantly higher in the group without cysteamine supplementation than in the other groups (36.5 ± 2.51). Conclusions: According to the results of the present study, appropriate conditions for preserving the sperm parameters after cryopreservation could be created by adding cysteamine to the sperm cryopreservation media as an antioxidant effective on sperm parameters.
背景:精子低温保存会降低精子质量。抗氧化剂可以通过减少氧化应激来改善精子参数。目的:研究在精子冷冻培养基中添加半胱胺对精子冷冻后质量的影响。方法:这项描述性分析研究于2022年在伊朗Dezful的Omolbanin不孕症治疗中心进行。这些样本包括60名符合世界卫生组织标准的正常精子男性。每个样本分为三个部分:1。新鲜精液组,2。用10毫摩尔半胱胺冷冻精液,3。没有补充半胱胺的冷冻精液。对其活力、运动性、形态、总抗氧化能力(TAC)和丙二醛(MDA)水平进行评估。结果采用SPSS版本22进行描述,认为显著性水平P≤0.05。结果:新鲜精液组进行性运动平均值(48.3±4.74)明显高于其他两组。未添加半胱胺组的平均进行性运动指数(24.4±3.38)明显低于添加半胱胺组(35.3±4.9)。此外,添加半胱胺组TAC(816.6±4.36)显著高于其他各组。我们发现,未添加半胱胺组的MDA水平显著高于其他组(36.5±2.51)。结论:根据本研究结果,在精子冷冻保存培养基中添加半胱胺作为对精子参数有效的抗氧化剂,可为精子冷冻后参数的保存创造合适的条件。

: The urachus closes naturally after birth. Its opening leads to anomalies in which secondary complications, including urachus calculi, may be formed. This disease is often discovered incidentally in radiographic examinations and is rare in adults. The purpose of this study is to present a rare case of urachus calculus in an adult located precisely in the anterior wall of the bladder, at the junction of the bladder and urachus. Our case was a 38-year-old man with complaints of abdominal pain. The computerized tomography (CT) scan images showed a calculus attached to the anterior and inner wall of the bladder in inserting the urachus into the bladder. Cystoscopy showed the calculus is connected to the urachus duct without any mass/tumor. The collection of evidence suggests a calcified urachus. The patient was discharged with conservative treatment and a mild analgesic.
胎儿出生后,输卵管自然闭合。其开口导致异常,可能形成继发性并发症,包括尿管内结石。此病常在影像学检查中偶然发现,在成人中罕见。本研究的目的是提出一个罕见的病例尿路结石的成人恰好位于膀胱前壁,在膀胱和尿路交界处。我们的病例是一位38岁的男性,主诉腹痛。计算机断层扫描(CT)图像显示,在将尿囊插入膀胱时,结石附着在膀胱前壁和膀胱内壁上。膀胱镜检查显示结石与尿管内相连,未见肿块/肿瘤。证据表明这是一个钙化的urachus。患者在保守治疗和轻度止痛药治疗下出院。
