A family study of bladder exstrophy. (44/48)

The families of 102 index patients with bladder exstrophy treated at The Hospital for Sick Children, Great Ormond Street were studied in an attempt to arrive at an empirical risk of recurrence for sibs. Of the 102 patients, 89 had complete exstrophy, eight had partial exstrophy (variant), and five had exstrophy of the cloaca. In all they had 162 sibs, none of whom had bladder exstrophy. The risk to sibs, in this study and from reports by surgeons of sib pairs in their consecutive series, is low and probably less than 1%. There is a suggestion of an increase in central nervous system malformation in sibs as well as in the index patients.  (+info)

Four cases of bladder exstrophy in two families. (45/48)

Bladder exstrophy is a rare congenital anomaly, caused by abnormal development of the cloacal membrane. To our knowledge, 18 familial patients with this malformation have been described. Two sets of familial cases with bladder exstrophy are reported here: two cousins and a mother and son and the published reports of the 18 familial cases among 682 index patients with bladder exstrophy are reviewed. Ultrasonography is advocated as the investigation of choice for early prenatal diagnosis.  (+info)

Flaps for the repair of bladder exstrophy. (46/48)

From April 1986 to March 1992, flaps were used in the surgical treatment of 17 patients with congenital bladder exstrophy. Eleven of these patients had had surgery in other hospitals but all failed. Using the flap method for the repair all of them had procured a functional bladder except one who could not have a complete control of urination. The longest follow-up period was 3 years, and the renal and bladder functions were completely normal. The immediate result in 14 patients was good in the control of urination right after the removal of the catheter. The follow-up results were good in 16 cases. The flaps used included 8 types of skin flaps, fasciae and vascular pedicles. Provided with the central vascular supply, the new series of procedures were suitable for the treatment of a variety of exstrophy deformities.  (+info)

Bladder exstrophy from childhood into adult life. (47/48)

Exstrophy of the bladder is rare and the incidence of bladder exstrophy is calculated to be from 1 per 30,000 to 50,000 live births with male to female ratio ranging from 1.5-5 to 1(1-4). It was found that persistence or overgrowth of the cloacal membrane on the lower anterior abdominal area, prevents normal mesenchymal ingrowth. This causes divergence of the lower abdominal muscular structures and forces the genital ridges to fuse caudal to the cloacal membrane. The stage of ingrowth of the urorectal septum at the time of rupture determines whether one will produce an exstrophic urinary tract alone (classic bladder exstrophy or epispadias) or cloacal exstrophy with the hindgut interposed between the hemibladders.  (+info)

Follow-up of 13 children after ureterosigmoidostomy. (48/48)

Follow-up of 13 children who had had a ureterosigmoid anastomosis 3 1/2 to 10 years previously and whose initial urogram had been satisfactory, showed that growth was normal and that there was no serious metabolic disorder. In particular whole-body potassium did not differ significantly from normal values (as given by Langham, 1961). Asymptomatic urinary infection is the chief hazard in these cases but is difficult to diagnose and may lead to progressive dilatation of the ureters.  (+info)
