Twenty-eight children with bladder exstrophy, prior to surgery for continence, underwent a urodynamic evaluation, cystogram, ultrasound and dimercaptosuccinic acid scan, to define parameters of lower urinary tract function that are a risk for upper tract damage and/or impair development of bladder capacity. The bladders in 7 of 28 demonstrated no storage function [leak pressure)LP) = 0]; but storage parameters could be measured in the other 21. Their LP was 10-35 cm H2O; 17 of 21 revealed involuntary contractions and 7 of 21 had an end-fill pressure greater than 10 cm H2O. Bladder capacity was better in those with a higher LP and those with no involuntary contractions. The 4 patients with bilateral hydronephrosis (3 of whom also had bilateral multiple scars) were among the 6 with LP greater than 30 cm H2O. Of the 7 with an end-fill pressure greater than 10 cm H2O, 5 had upper tract damage. Involuntary contractions may impair development of capacity. A LP of greater than 30 cm H2O is a risk factor for upper tract damage and an end-fill pressure greater than 10 cm H2O may also be a factor.
This is an update of a consecutive series of 19 patients with bladder exstrophy presented as a preliminary report 10 years ago with a follow-up of 6 years. The average time of follow-up now is 14 years. In difference to the former report several additional procedures have been performed in most patients. 3 early "good" patients stay "good and continent". Only 3 out of 5 patients categorized as "fair" are now "good and continent" and only one without further intervention. 3 out of 6 patients who were classified as "poor" are now diverted. The overall rate of secondary diversions is 40% including 2 patients with ureterosigmoidostomies. All patients have normal renal function and normal blood pressures. These results show that an early "good" result generally remains "good" but additional surgery may be warranted. The initially "fair" results usually necessitate a secondary procedure, e.g. augmentation cystoplasty or/and bladder neck tightening to show an improvement. Patients with early "poor" results unfortunately remain "poor" and have a great chance to get diverted.
