The use of LiCl in clinical psychiatry is routinely complicated by overt nephrogenic diabetes insipidus (NDI), the mechanism of which is incompletely understood. In vitro studies indicate that lithium can induce renal medullary interstitial cell cyclooxygenase 2 (COX2) protein expression via inhibition of glycogen synthase kinase-3beta (GSK-3beta). Both COX1 and COX2 are expressed in the kidney...

Introduction: Nocturia is categorized into many categories. Each category requires different approaches and treatment. We aimed to obtain data regarding nocturia, classified into categories according to its pathogenesis, in Thai patients. Methods: We reviewed 133 medical records and voiding diaries of the patients who attended a urologic clinic in a tertiary teaching hospital during year 2009-2...

PURPOSE The precise etiology and classification of nocturia in women is not enough. We evaluated age related changes and classified the type of nocturia by age in women. METHODS We included 118 women 20 years or older with nocturia at least one time during night time. Subjects were divided into three groups by the age: group 1, under 40 years; group 2, 40 through 59 years; group 3, 60 years a...

Urinary dysfunction is a common complaint following spinal cord injury (SCI) and is a leading issue for individuals with SCI that impacts their quality of life. One urinary complication that has received little attention is SCI-induced polyuria, even though individuals with SCI will significantly restrict their fluid intake to decrease urine production, leading to sequelae of medical complicati...

The mechanism of lithium-induced diabetes insipidus was investigated in 96 patients and in a rat model. Polydipsia was reported by 40% and polyuria (more than 3 liter/day) by 12% of patients receiving lithium. Maximum concentrating ability after dehydration and vasopressin was markedly impaired in 10 polyuric patients and was reduced in 7 of 10 nonpolyuric patients studied before and during lit...

BACKGROUND We investigated risk factors for lower urinary tract (LUT) dysfunction and LUT symptoms in patients who successfully underwent renal transplantation (RTX). MATERIAL AND METHODS Ninety-five patients (54 males and 41 females) undergoing RTX (median age: 45 years old) at Hokkaido University Hospital were included in this study. Uroflowmetry (UFM), postvoid residual urine volume (PVR),...
