Kidney function after methoxyflurane analgesia during labour.

In a study of the effects of methoxyflurane on renal function, the urinary and blood urea concentrations, the urinary and plasma osmolalities, and the packed cell volume were studied in each of 50 mothers before and after delivery. Methoxyflurane 0.35% was used as an analgesic in 25 patients and the other 25 had 50% nitrous oxide and 50% oxygen (Entonox). There was no evidence of renal dysfunction in either group, nor were there any significant differences between the groups. In a further 200 mothers, of whom 100 had methoxyflurane and 100 had nitrous oxide analgesia, the urinary and blood urea concentrations were measured on the morning of discharge from hospital. There were no significant differences between the groups. These results suggest that methoxyflurane is not nephrotoxic when used as a self-administered analgesic.

Clinical significance of dysuria in women.

During a community survey 22% of women were found to have had dysuria in the previous year and half had had dysuria at some time in their lives. Various measurements were made in a random sample of 282 of these women. The means and the variances of the systolic and diastolic blood pressures in women with a past history of dysuria tended to be higher than in women who gave no such history. There were no significant differences in the means of plasma urea, plasma creatinine, and renal concentrating power between women with and without a previous history of dysuria, but a significant impairment of renal concentrating power was found in an additional group of 30 women who dated the onset of their dysuria to childhood.These findings suggest that urinary tract infection in adult women does not usually lead to progressive impairment of kidney function, whereas infection in childhood is more often associated with kidney damage.

Asymptomatic significant bacteriuria in the non-pregnant woman. I. Description of a population.

The clinical, laboratory, and radiological findings in a group of 107 non-pregnant bacteriuric women and 88 controls have been compared. A previous history of urinary tract infection was more commonly obtained from the bacteriuric women. The means of the diastolic blood pressures, serum ureas, and erythrocyte sedimentation rates were significantly higher in the bacteriuric group, and acquired renal abnormalities were demonstrated in 18% of the bacteriuric women as compared with 4% of the controls. It is concluded that screening for asymptomatic bacteriuria in the adult non-pregnant female population in many instances fails to detect urinary tract infection at an early and reversible stage.

Asymptomatic significant bacteriuria in the non-pregnant woman. II. Response to treatment and follow-up.

Short courses of nitrofurantoin and ampicillin produced an immediate cure in 80% of adult non-pregnant bacteriuric women. Of the subjects so treated, 55% remained cured at the end of one year. Over the same follow-up period 36% of untreated bacteriuric women developed a spontaneous remission of bacteriuria. Treatment failed to prevent the development of symptomatic infection, and the reinfections which followed successful treatment were more commonly associated with the development of symptoms than the persistent or relapsing infections in untreated or unsuccessfully treated subjects.It is concluded that a search for bacteriuria in non-pregnant women is unlikely to be of value as a preventive measure, since in many instances it fails to detect urinary tract infection at an early stage and since treatment by methods suitable for large-scale use is ineffective.
