A 55-year-old woman was referred to our hospital with dysuria. We were unable to catheterize her using a nelaton catheter because of a urethral stricture, resulting in a large residual urine volume on ultrasonography. The circumference of the periurethral tissue was also thickened and the entire length of the urethra was stenotic, without apparent cause, on magnetic resonance imaging. Biopsy did not reveal malignancy. The pathological diagnosis of the periurethral tissue was simply fibrosis, and there was no definitive diagnosis...

Holmium laser enucleation of the prostate (HoLEP) is a standard surgical procedure for treatment of benign prostatic hyperplasia (BPH). A low incidence of postoperative urinary incontinence in association with anteroposterior dissection HoLEP was recently reported. We evaluated 66 patients with BPH who underwent anteroposterior dissection HoLEP from March 2013 to November 2014. The International Prostate Symptom Score (IPSS), quality of life (QOL) index, maximum flow rate (Qmax), and post-void residual urine volume (PVR) were assessed preoperatively and at 1 and 3 months after treatment...

Approximately 8 million health care workers are unnecessarily exposed to highly toxic drugs used to treat cancer; antineoplastic drugs can contribute to negative health effects for these workers. The drugs have been detected in the urine of workers and on the floors and counters of worksites. Safety precautions that could reduce the risk of exposure are underutilized. This cross-sectional study of 163 oncology health care workers used a survey to measure workplace and individual factors, and environmental sampling to measure surface contamination...

Many patients on hemodialysis retain significant residual renal function (RRF) but currently measurement of RRF in routine clinical practice can only be achieved using inter-dialytic urine collections to measure urea and creatinine clearances. Urine collections are difficult and inconvenient for patients and staff, and therefore RRF is not universally measured. Methods to assess RRF without reliance on urine collections are needed since RRF provides useful clinical and prognostic information and also permits the application of incremental hemodialysis techniques...

Different highly selective sorbents have been evaluated for the treatment of food and biological samples to determine chloramphenicol residues by ion mobility spectrometry (IMS). Combination of a selective solid-phase extraction (SPE) and dispersive liquid-liquid microextraction allowed a highly sensitive determination of chloramphenicol in water, milk, honey, and urine samples. The performance of selective SPE supports such as immunoaffinity chromatography (IAC) and molecular imprinted polymers (MIP) have been compared in terms of selectivity, sensitivity, trueness, precision, and reusability...

Guidelines for monitoring multiple myeloma patients expressing light chains only (light chain multiple myeloma; LCMM) rely on measurements of the monoclonal protein in urine. Alternatively serum free light chain (sFLC) measurements have better sensitivity over urine methods, however, demonstration that improved sensitivity provides any clinical benefit is lacking. Here we compared the performance of serum and urine measurements in 113 (72κ, 41λ) newly diagnosed LCMM patients enrolled onto the IFM-2009 trial...

Besides their development for therapeutic purposes, non-steroidal selective androgen receptor modulators (non-steroidal SARMs) are also known to impact growth associated pathways as ligands of androgenic receptors (AR). They present thus a potential for abuse in sports and food producing animals as an interesting alternative to anabolic androgenic steroids (AAS). These compounds are easily available and could therefore be (mis)used in livestock production as growth promoters. To prevent such practices, dedicated analytical strategies have to be developed for specific and sensitive detection of these compounds in biological matrices...

Triclosan (TCS) is a broad spectrum antibacterial agent present as an active ingredient in some personal care products such as soaps, toothpastes and sterilizers. It is an endocrine disrupting compound and its increasing presence in water resources as well as in biosolid-amended soils used in farming, its potential for bioaccumulation in fatty tissues and toxicity in aquatic organisms are a cause for concern to human and environmental health. TCS has also been detected in blood, breast milk, urine and nails of humans...

Residual kidney urea clearance in dialysis patients typically is calculated as the per minute excretion of urea nitrogen, obtained during the 24-48 hour collection period that usually ends just prior to a dialysis session, divided by the time-averaged serum water urea nitrogen concentration during the collection period. This concentration is difficult to estimate unless a formal kinetic modeling program is being used. We used a urea kinetic modeling program to derive an equation to estimate the time-averaged serum water concentration during urine collection periods of various lengths collected during various interdialytic intervals, for 3/week or 2/week dialysis schedules...

The differentiation of clenbuterol abuse and unintentional ingestion by contaminated meat is crucial with respect to the valuation of an adverse analytical finding in human sports doping control. The proportion of the two enantiomers of clenbuterol may serve as potential discriminating parameter. For the determination of the individual enantiomers, specific methods were developed and validated for the different matrices under investigation based on chiral chromatography coupled to tandem mass spectrometry. Data from the administration of clenbuterol from a pharmaceutical preparation and from cattle meat and liver containing residues to humans are presented...

BACKGROUND: Recent reports have suggested the possible benefit of beginning hemodialysis (HD) at a rate less frequent than three times weekly and incrementally increasing the dialysis dose. However, the data regarding the benefits and safety of incremental HD are insufficient. METHODS: We analyzed 927 patients with newly initiated HD from the Clinical Research Center for End-Stage Renal Disease cohort from 2008 to 2014. The patients were classified into a thrice-weekly initiation group or an incremental initiation group (one to two sessions per week) according to the frequency of HD per week at baseline...

Activation of the thick ascending limb (TAL) Na+-K+-2Cl--cotransporter (NKCC2) by the antidiuretic hormone arginine-vasopressin (AVP) is an essential mechanism of renal urine concentration and contributes to extracellular fluid and electrolyte homeostasis. AVP effects in the kidney are modulated by locally and/or by systemically produced epoxyeicosatrienoic acid derivates (EET). The relation between AVP and EET metabolism has not been determined. Here we show that chronic treatment of AVP-deficient Brattleboro rats with the AVP V2 receptor analog desmopressin (dDAVP; 5ng/h, 3d) significantly lowered renal EET levels (-56 ± 3% for 5,6-EET, -50 ± 3...
