Asymptomatic bacteriuria in schoolgirls. III. Relation between residual urine volume and recurrence.

Residual urine volume (RUV) has been measured in 70 schoolgirls with asymptomatic bacteriuria using 121I-hippuran. The mean volume of residual urine was 23.7 ml. More than 5 ml RUV, the highest value found in 14 girls without bacteriuria or a history of urinary tract infection, was found in 47% of the patients. The mean volume for residual urine in the control girls was 1-1 ml. Among the 44 girls cured for their bacteriuria be a bladder wash out test or antibiotic treatment, recurrence was significantly more common (p less than 0.001) in those greater than 5 ml in RUV (45/20, 75%) than in those with less than or equal to 5 ml (4/24, 17%). In 5 of 22 patients not treated, the bacteriuria disappeared spontaneously during a one year observation period. The RUV was less than 3 ml in 4 of these 5 girls. While the presence of residual urine per se may not be the primary event leading to bacteriuria, it may increase the risk of recurrences, by facilitating bacterial growth and impairing the wash out of bacteria from the bladder on micturition.

Lung volumes in scoliosis before and after correction by the Harrington instrumentation method.

Studies of static lung volumes were performed before and after surgery in 92 scoliotic patients, aged 10 to 25 years. The majority of the patients had idiopathic dorsal curves. Vital capacity, total lung capacity, functional residual capacity and residual volume were measured at least 18 months after surgery. A significant increase was observed in all static volumes, averaging 10 per cent; the pre- and postoperative values were expressed in per cent of predicted normal values according to age and height. Correction of body height was taken into consideration in the prediction of normal values. Patients with the more advanced scoliosis had the greatest improvement in lung volumes. The patients were treated postoperatively with a Milwaukee brace for an average of 15 months. The use of this brace, which allows for chest expansions, might account for the improved lung function compared to previous series where plaster body jackets were used. Thus the correction of idiopathic scoliosis by the standard posterior fusion with Harrinton instrumentation together with our postoperative routine provides a lasting reduction of the spinal deformity, prevents progression of respiratory impairment and, in fact, increases the lung volumes, vital capacity, total lung capacity and functional residual capacity by an average of 10 per cent.
