Clinical application of the second morning urine method for estimating salt intake in patients with hypertension

Abstract

Estimation of salt intake by cumbersome 24-h urine collection is not suitable for individual patients because of substantial daily variation in intake. We developed the second morning urine (SMU) method for monitoring daily salt intake in healthy subjects by calculating the daily creatinine excretion and measuring the ratio of sodium to creatinine in the SMU specimen. To determine whether the SMU method was applicable to hypertensive patients, we tested it in hospitalized patients under an equilibrated sodium balance as a model population. This review focuses on application of the SMU method in hypertensive patients with mild target organ damage.     

Urinary albumin excretion in a population based sample of 1011 middle aged non-diabetic subjects

Jensen JS, Feldt-Rasmussen B, Borch-Johnsen K, Jensen G and The Copenhagen City Heart Study Group. Urinary albumin excretion in a population based sample of 1011 middle-aged non-diabetic subjects. Scand J Clin Lab Invest 1993; 53: 867-872

Increased urinary albumin excretion rate (UAER) especially in the range of 20-200 μg min^?1, termed microalbuminuria, has been proposed as a risk marker and predictor for cardiovascular disease in non-diabetic subjects. Thus it would be of importance to describe the distribution of UAER in the non-diabetic population. Among 1011 30-70-year-old subjects without diabetes mellitus or urinary tract infection, who were invited to participate in a population based epidemiological study, the albumin concentration was measured in an overnight urine sample. The measurement was performed by an ELISA method. The UAER was calculated in units of μgmin^?1 as urinary albumin concentration × urine volume/urine collection time. The distribution of UAER was positively skewed with a median value of 2.3μgmin^?1 and a 5-95 inter-percentile range of 0-11.0μgmin^?1. The UAER held constant with age, but males had higher UAER than females, 2.6 (0-13.5)μgmin^?1 vs 2.2 (0-8.3)μgmin^?1; p < 0.005. The prevalence of microalbuminuria, defined as an UAER in the range of 15-150μgmin^?1 in an overnight urine sample, was 3% (95% C.I. interval: 1.9-4.0). These findings suggest, that the level of UAER which might notify increased cardiovascular risk, is lower than in patients with diabetes mellitus, if it is considered to be of any clinical relevance.     

Factors Provoking Lower Urinary Tract Infection in Women

Our aim was to evaluate possible risk factors, other than sexual activity, for urinary tract infection (UTI) in women. A case-control study was designed. 50 cases and 50 controls were included.

A larger fraction of cases than controls reported that episodes of the following preceded the UTI: voluntary deferred voiding (Odds ratio 5.0, 95% confidence interval 1.7; 20.1), cold hands (4.7, 1.3; 25.3), cold feet (5.8, 2.0; 22.8), and cold buttocks (5.5, 1.2; 51.0).

Cold body parts should be further evaluated as a possible risk factor for UTI in UTI-prone women.     

体外冲击波碎石治疗泌尿系结石8702例临床总结

目的探讨体外震波碎石（ESWL）治疗泌尿系结石的临床效果。方法回顾性分析ESWL治疗的8702例泌尿系病人的临床资料。结果7572例泌尿系结石2月内排尽；673例6月内排尽；376例未排尽；81例无效，无效者在最后一次治疗后1月行开放性手术。结论ESWL是治疗泌尿系结石的首选方法，安全有效，易被患者接受，但要注意病例的选择。     

无张力阴道吊带术治疗女性压力性尿失禁(附20例报告)

目的 评价无张力阴道吊带术(tension-free vaginal tape，TVT)治疗女性压力性尿失禁的疗效。方法 总结采用TVT术治疗女性压力性尿失禁20例的临床资料。结果 平均手术时间26.5min。拔除尿管后，19例病人控尿满意，1例仍有轻微尿失禁。术后平均随访12(3-24)个月，20例病人均无尿失禁。合并症有1例膀胱穿孔，1例术后轻度排尿不畅，2例尿频尿急。结论 TVT术操作简便快捷，创伤小，合并症少，术后康复快，是一种治疗女性压力性尿失禁的理想方法。     

产后盆底肌训练对盆底功能的恢复效果观察

目的观察产后盆底肌训练对提高盆底肌力、改善尿失禁及盆腔脏器脱垂的效果。方法选取94例产后盆底功能障碍性疾病患者,随机分为两组,各47人。观察组采用标准的盆底肌训练,每周进行2次,5周为1个疗程;对照组完成相关健康教育和练习产后操。两组患者治疗前后均进行盆底肌力测定以及评价压力性尿失禁和盆腔脏器脱垂的发生情况。结果观察组与对照组盆底肌力治疗有效率分别为66.0%和89.4%,压力性尿失禁治疗有效率分别为59.6%和78.7%,盆腔脏器脱垂治疗有效率分别为57.4%和74.5%,差异均有统计学意义(P<0.05)。结论产后盆底肌训练对提高盆底肌力、改善尿失禁及盆腔脏器脱垂效果较好,值得推广应用。     

改良TIP尿道成形术:恢复尿道解剖结构

目的 分析尿道板背侧纵切卷管尿道成形术(TIP)基础上覆盖Buck筋膜联合尿道海绵体(BC)和背侧包皮筋膜组织(P)在无阴茎下弯或轻度阴茎下弯的小儿中远段型尿道下裂的治疗效果。 方法 回顾性分析104例中远段型尿道下裂患儿的病例资料。其中行BC-P-TIP手术72例(A组); 行传统术式TIP+背侧包皮筋膜组织(P-TIP手术)32例(B组)。术后1,3,12月进行门诊随访。术后3月参照尿道下裂客观评分系统(HOSE)对患儿进行手术效果评估,对两组病例的一般资料、HOSE评分、并发症情况进行统计学分析。 结果 A,B组术后3月HOSE评分平均分分别为15.42及13.90,差别有统计学意义(P<0.01)。A,B组的尿瘘发生率为8.3%及25%,差别有统计学意义(P<0.05)。A,B组的尿道狭窄发生率为4.2%及0%,差别无统计学意义(P>0.05)。 结论 BC-P-TIP改良术式相对于P-TIP术式能有效减少尿瘘发生,术后外观满意、排尿功能良好,手术操作简单易学,取材方便,解剖损伤小,且接近正常尿道的解剖结构,值得进一步探讨及推广。
