introduction: hydronephrosis is one of the major causes of referring infants for nuclear medicine investigation. renal dynamic study is the most reliable investigation for such children. however direct evaluation of renogram leads to generation of parameters that have no physiological interpretation. the configuration of renogram is very much dependent upon the rate at which radiopharmaceutical...

The pervasiveness of urinary tract infections (UTIs) with their clinical manifestations in patients with diabetes mellitus has escalated amidst the past decade or so, as myriad predisposing factors contribute to its occurrence. Although the causative agent of UTI is Escherichia coli, the etiopathogenesis can be traced back to glycosuria in the renal parenchymal region. This has precipitated pye...

Sodium Retention Sodium retention is probably the most common renal function abnormality in patients with cirrhosis and ascites and plays a key role in the pathophysiology of ascites and edema formation. It is the first manifestation of renal impairment cirrhotics develop. It appears before ascites formation, impaired free water excretion and functional renal failure (Figure 1). This observatio...

Year patients suggested powerful renal vasoconstriction, possibly due to neurogenic or humoral influences. The stimulus to this might be a raised renal pelvic pressure, although this is, however, appreciably lower than the bladder pressure measured concurrently.' Surgical relief of chronic retention was accompanied by a prompt and sustained rise in glomerular filtration rate and effective renal...

A case of advanced, reversible renal failure due to psychogenic urinary retention occurring in a 17 year old female, is reported. The diagnosis of psychogenic urinary retention was made on the basis of existent florid psychopathology and the concomitant exclusion of an organic cause. Family psychodynamics are discussed. Psychosocial intervention led to a resumption of normal micturition, the di...
