131 patients with chronic renal failure treated with furosemide, which is a drug in the treatment of oedema and hypertension. In chronic renal failure with chronic glomerulonephritis, the glomerular filtration rate rises after administration of furosemide in stage I of chronic renal failure. Long term administration of high dose of furosemide did not ameliorate renal function in stage chronic renal failure with chronic glomerulonephritis.

BACKGROUND/AIMS: Transtubular potassium gradient(TTKG) is known as the most accurate indicator of aldosterone activity. TTKG may be used to monitor the effectiveness of aldosterone antagonist which is prescribed generally for the management of cirrhotic ascites. Spot urine [Na]/[K] ratio may also be used for the same purpose. METHODS: After measuring TTKG, spot urine [Na]/[K] ratio, and plasma aldosterone concentration in each of the 23 patients all who had cirrhotic ascites, 100 mg of spiron-olactone was prescribed to be taken daily for 5 days. When no diuretic response occurred and TTKG was more than 3.5 at the end of 5 days, the dose of spironolactone was increased by 100 mg/day at the interval of 5 days until TTKG decreased to below 3.5. Furosemide was added to the non-responders if their TTKG had dropped to below 3.5. RESULTS: Basal plasma concentration of aldosterone was higher than upper normal limit in 13(57%) patients, and correlated with TTKG significantly(r=0.60, p=0.002). TTKG was calculated to be 3.5+/-0.67 when assuming the aldosterone activity has been completely blocked. Spot urine [Na]/[K] ratio had significant negative correlation with TTKG before and after the administration of spironolactone. In most patients, diuretic response appeared with the fall of TTKG (especially below 3.5) and with the rise of spot urine [Na]/[K] ratio. In patients who did not respond to a low dose spironolactone, further treatment plan (to increase dose of spironolactone or to add furosemide) was guided by TTKG, and all were successful. CONCLUSIONS: TTKG and spot urine [Na]/[K] ratio are good indicators of aldosterone activity, and might be used as useful guidelines in the diuretic management of cirrhotic ascites.

This study was undertaken to compare the effects of furosemide on the serum concentration of sodium and osmolality after transurethral prostatic resection(TURP) using cytal solution, and to determine the adequate time of administration of frurosemide. At the end of prostatic resection, 15 patients were allocated randomly to receive furosemide (furosemide group) and were compared with 15 patients without administration of furosemide (control group). There was no difference in mean serum concentation of sodium between two groups. Serum osmolality in furosemide group was significantly increased as compared with control group one hour after operation. So cytal solution used during staged TURP and short operation within one hour do not affect serum corcentration of sodium and administration of furosemide is not associated with a change in serum concentration of sodium. But furosemide meaningfully increases the serum osmolality and it is more effective to administer it with administration at the end of prostatic reseetion.

BACKGROUND: The interactions between furosemide and muscle relaxants is controversial. In this study, the effects of furosemide on the recovery from neuromuscular blockade induced by vecuronium were investigated in thirty ASA class 1 or 2 adult patients undergoning elective orthopedic surgery under the general aneshtesia with O2-N2O-enflurane. METHODS: Furosemide was administered intravenously at 20% spontaneous recovery of first twitch height of TOF(T1) under the neuromuscular monitoring using Relaxograph?(Datex Co. Finland) as follows: placebo in control group, 5mg in group 1 and 20mg in group 2. Recovery index(RI) defined as the time from 25% to 75% recovery of T1, urinary output during this period and serum K+ levels at 10% and 75% recovery of T1 were measured. RESULTS: RI was shortened significantly in group 1 (11.2+/-3.4 min.) and group 2 (14.9+/-2.7 min.) compared with control group (19.3+/-4.0 min.)(P<0.05). The urinary output was significantly greater in the groups received furosemide than that in the control group(P<0.05), but serum K+ levels were not significantly changed after administration of furosemide. CONCLUSIONS: Furosemide facilitates recovery of neuromuscular blockade induced by vecuronium.

PURPOSE: A prospective randomized controlled trial was performed to investigate the effects of intravenous hydration, both with and without diuretics, on the fragmentation and passage of an upper ureteral stone during ESWL. MATERIALS AND METHODS: We analyzed 65 patients with upper ureteral stones, primarily treated with piezoelectric LT-02 lithotripter, between November, 2001 and March, 2002. The patients were divided in 3 groups; the 20 patients in group A were injected with 500ml of normal saline for intravenous hydration, and 20mg of furosemide for diuretic effect during the ESWL; the 20 patients in group B were injected with normal saline without furosemide, and the remaining 25, group C, were used as controls. The same energy settings for the shockwaves in one session were equally applied to all the patients during the ESWL, with a 4Hz shockwave frequency, 100% power, a 50 minute treatment and 43 minute storage time. After 2 weeks, the degrees of stone fragmentation, and the residual fragments, were evaluated on the post-ESWL KUB and compared with the pre-ESWL KUB. RESULTS: After a single ESWL treatment, the stone-free rate was 70% (14 of 20 patients) in group A, 60% (12 of 20 patients) in group B and 28% (7 of 25 patients) in group C (p<0.05). The stone-free rates of groups A and B were significantly higher than that of group C, but there was no statistical difference between groups A and B. The stone-free rates, after a single session, according to the stone size was higher in groups A (77.8%) and B (73.3%) than in group C (38.9%) for stones smaller than 10mm (p<0.05), but they were similar between the three groups for stones larger than 10mm (p>0.05). CONCLUSIONS: Intravenous hydration with normal saline, both with and without a furosemide injection for diuretic effect, during ESWL would be an effective method to facilitate the fragmentation and passage of upper ureteral stones smaller than 10mm.

Breathlessness is a frequent and distressing symptom in terminal cancer patients. Refractory breathlessness is defined as a state that does not respond to conventional disease-specific therapy with an exclusion of reversible underlying causes, and the main classes of symptomatic drug treatments include opioids and benzodiazepines. Korean Family Medicine Palliative Medicine Research Group discussed two terminal cancer patients in whom severe breathlessness with different causes were treated with inhalation of nebulized furosemide, which is an emerging option of palliative treatment. It still remains unclear how it becomes effective or how much it is effective, therefore, its routine use seems to be somewhat early. Nevertherless, if a patient with intractable breathlessness does not have a marked obstructive airway lesion, its use should be considered. Based on the discussion in the seminar, we want to share our experience of the application of inhaled furosemide with other palliative care practitioners and strongly recommend further research on this topic in the future.

PURPOSE: Although ultrasonography and diuretic renography are routinely performed for evaluation of ureteropelvic junction obstruction, no reported studies have systemically investigated the correlation of the two methods. We investigated the correlation and values of the two methods. MATERIALS AND METHODS: We studied 44 patients who presented with unilateral hydronephrosis due to ureteropelvic junction obstruction from 1994 to 1999. Patients were evaluated with ultrasound and nuclear renograms with furosemide. Hydronephrosis grade on ultrasonography and the severity of obstruction on diuretic renography were in accordance with the SFU (Society for Fetal Urology) system and "The Well Tempered Renogram", respectively. RESULTS: 27 patients showed grade III hydronephrosis and the remaining 17 patients showed grade IV hydronephrosis on ultrasonography. Kidneys of grade IV hydronephrosis had poorer washout patterns on diuretic renography than those of grade III hydronephrosis (p <0.001). In regard of mean split renal function ratios, there was no statistically significant difference between two groups (p >0.05). In 37.0% (10/27) and 47.1% (8/17) of patients with grade III and grade IV hydronephrosis, hydronephrotic kidney had a differential function greater than 50%. CONCLUSIONS: Our study suggests that diuretic renography is not always indicated in the patients with grade IV hydronephrosis, but, must be performed to confirm the severity of obstruction in the patients with grade III hydronephrosis.

This study aimed to assess the effects of dehydration on echocardiographic indices in healthy cats: specifically, it aimed to assess the effects of volume depletion on diastolic function. Nine experimental cats were subjected to both a dehydration and placebo protocol separated by a 21-day washout period. Echocardiography was performed at baseline and on completion of each protocol. Results were compared between the two protocols. Volume depletion was induced by intravenous administration of furosemide. Volume depletion showed a significant association with increased interventricular septal and left ventricular free wall thickness at end-diastole, decreased left ventricular internal diameter at end-diastole, and left atrial diameter at end-systole. The peak early (E) and late (A) diastolic filling velocities, and the peak early diastolic velocities (E′) were significantly decreased by dehydration. Volume depletion did not affect peak longitudinal strain rate during early diastole, E/A, or E/E′. Volume depletion significantly affected the echocardiographic diastolic indices and conventional echocardiographic parameters in healthy cats.
