PURPOSE: We evaluated a method of estimating detrusor pressure at home in patients with myelomeningocele who perform clean intermittent catheterization to empty the bladder. MATERIALS AND METHODS: Patients with myelomeningocele who perform clean intermittent catheterization underwent cystometry. At home they determined bladder pressure before draining a full bladder and after partial draining with the bladder almost empty. Home estimate of detrusor pressure was calculated using the formula, full bladder pressure - almost empty bladder pressure. RESULTS: A total of 4 boys and 5 girls with a mean age plus or minus standard deviation of 9.6+/-7.9 years who were enrolled in our study made 16.9+/-15.2 home bladder pressure and volume recordings weekly each during a mean of 5.8+/-4.3 months. Mean bladder capacity determined at home was significantly greater than cystometric capacity (354+/-185 versus 250+/-146 ml.). At a mean home and cystometric volume of 190+/-110 ml. full bladder pressure at home was not significantly different from cystometric vesical pressure (31.0+/-8.8 versus 27.5+/-7.5 cm. water). At a mean volume of 23+/-15 ml. mean home almost empty bladder pressure was not significantly different from cystometric abdominal pressure at full and almost empty volumes (14.1+/-5.5 versus 17.0+/-7.4 and 15.5+/-5.8 cm. water). Mean home estimate of detrusor pressure was not significantly different from cystometric detrusor pressure (17.0+/-6.3 versus 10.2+/-9.2 cm. water). CONCLUSIONS: Estimation of detrusor pressure at home is reliable and accurate in patients who perform clean intermittent catheterization. These pressure determinations may be used as a baseline for rapid identification of changes in bladder function.
