Renal functional changes following relief of obstruction were investigated with a prospective aspect in a series of 15 postoperative patients using standard renal function measurements with emphasis on osmolar and free water clearance. Sequential measurements of free water clearance revealed earlier changes of postoperative renal function than that of standard renal function. The advantage of this measurement was in postoperative patients with adequate amount of urine output or diuresis. It may be helpful to the management of patients with obstructive uropathy and to early prediction of acute renal failure, especially in patients with post-obstructive diuresis.

The present experiment was designed to investigate renal function in conscious rabbits. Pentobarbital caused some reduction of urinary volume and hemohynamics, but the changes were not significant. UnaV, UkV, UclV were not changed by pentobarbital in dose of 3.0~9.0mg/kg i.v.. Urinary flow snd UclV were not changed by pentothal sodium, 5.0mg/kg i.v., but the UnaV and UclV increased from 30.61 to 66.19 uEq/min, from 28.29 to 62.91 uEq/min respectively, after pentothal sodium. There was no change in urinary potassium secretion after pentothal sodium. Left renal arterial infusion of pentothal sodium caused small changes in GFR, and clear increments of UnaV and UclV localized in that kidney in the urethane anesthetized rabbit. Natriuretic and chloruretic effect of pentothal sodium were not seen in mannitol diuresis. These data suggest that 1) the effects of pentobarbital and pentothal may not be the sam in conscious rabbit renal function, 2) natriuretic and chloruetic effect by pentothal may be caused by direct inhibition of sodium reabsorption in the distal nephron in the rabbit.

In this study, effects of the intraventricular and intravenous dimethylphenylpiperazinium (DMPP) on the renal function of rabbits were investigated. Intraventricular DMPP (100 microgram) elicited diuresis following antidiuresis concomitant with the changes in renal blood flow, glomerular filtration rate and urinary excretory amount of electrolytes (Na and K). The changes in urine flow correlated with the changes in renal blood flow, glomerular filtration rate and excretory rates of electrolytes in urine. Intravenous DMPP (50 microgram/kg) did not affect the renal function.

PURPOSE: This is a descriptive study conducted in order to survey sleep patterns and factors responsible for sleep disturbance among adolescent cancer patients after hospital admission. METHODS: The study group included 46 adolescent cancer patients aged 10 to 19 who received admission care in multi-bed hospital rooms from March to June 2016. Data on patterns and quality of sleep, and factors causing sleep disturbance were recorded using the Verran and Snyder-Halpern (VSH) Sleep Scale, the Pittsburgh Sleep Quality Index (PSQI), and a sleep disturbance questionnaire. RESULTS: There was no difference in patterns and quality of sleep prior to and after hospital admission in the study group. However, patients experienced sleep disturbance, as defined by PSQI > 5, both before (5.43) and after (6.30) admission. The most important physical, emotional and environmental factors causing sleep disturbance after admission were nocturnal diuresis, monotony of admission care, and crying of younger patients respectively. CONCLUSION: This study focused on sleep patterns and factors causing sleep disturbance after hospital admission for adolescent cancer patients. Future studies should aim to develop nursing interventions resulting in an environment that improves sleep quality. Additional studies should focus on developing daytime programs to determine the impact of admission care on other quality of life parameters.

Nocturnal polyuria is one of the main pathogenic mechanisms of enuresis. Disturbance of circadian rhythm of antidiuretic hormone (ADH or AVP), hypercalciuria, and/or solute diuresis are considered to cause nocturnal polyuria, which in turn causes enuresis in patients with relatively small bladder capacity and high threshold for awakening. Evaluation of these factors would guide the therapeutic approach for enuresis.

BACKGROUND: Low dose dopamine is widely used during the perioperative period to preserve renal perfusion. Low dose dopamine (3-5 microgram/kg/min) was administrated to partial hepatectomy patients and BUN, creatinine in serum were measured to determine the effects of low dose dopamine on renal function. METHODS: Liver group (n = 28) were administered low dose dopamine (3-5 microgram/kg/min) and the stomach group (n = 23) were not administered any vasoactive drugs during the operation. Perioperative plasma BUN, and creatinine, creatinine clearance, BUN/creatinine ratio, serum Na+ and K+, and central venous pressure (CVP) were checked 3 times, just after starting operation, 4 hours after starting the operation, and at PACU for both groups. We also evaluated intravascular volume status using the CVP and the BUN/creatinine ratio. Changes in BUN, and creatinine level during the operation in both group were compared. All the patients in this study were confirmed as having euvolemia by CVP and BUN/creatinine ratio. RESULTS: Urine volume increased significantly in the liver group with low dose dopamine compared to the stomach group (P < 0.05). The BUN level in the liver group increased significantly versus the stomach group (P < 0.05). In both groups, the creatinine level increased significantly (P < 0.05) and the plasma Na+ level decreased significantly (P < 0.05). CONCLUSIONS: We confirmed that low dose dopamine significantly increases urine volume in euvolemia status cases during liver surgery. But we were unable to determine why increased diuresis by the administration of low dose dopamine during operation and has a renal protective effect.

It is well recognized that dilation of upper urinary tract can occur in the absence of either reflux or mechanical obstruction. The demonstration of the cause of upper urinary tract dilation may critically alter the management of a patient. So several diagnostic methods were designed to demonstrate it, but their clinical application were not satisfactory due to inaccuracy, invasiveness and technical difficulty. Diuresis renography has recently been introduced as a method of evaluating upper urinary tract dilation found on intravenous urography. It is a simple, rapid, non invasive test which has enable to define the cause. 23 cases which have equivocal upper urinary tract dilation on intravenous urography were examined by diuresis renography in the Department of Urology, Kyung Hee University Hospital, during the period from October 1980 to March 1982 and three differential categories were obtained as follows. 1. Normal type (9 cases): Both standard and diuresis renograms were normal. 2. Obstructive type (3 cases): Initial renogram was obstructive and remained so during diuresis. 3 cases in this category were confirmed by operation and follow-up intravenous urography. 3. Atonic type (11 cases): Initial renogram tracing was obstructive but rapid isotope elimination occurred after diuresis.
