[Vascularization of the posterior wall of the urinary bladder in women after past cesarean section in light of microangiographic studies].
Arterial vascularization of membranes in the urinary bladder wall has been studied in 14 women of reproductive age, who were bearing children. Four of them had exclusively spontaneous deliveries. Ten delivered at least once by cesarean section. The studies consisted in filling the uterine, ovarian and vesical arteries with Microtrast preparation. After the filling of vessels and fixation of the preparation in 10% formalin solution, specimens, 4-5 mm thick, were taken from the bladder wall at the junction with uterus, and comparatively specimens from the free parts of the uterus body. The serial specimens were used to obtain photographs by means of X-ray apparatus with microfocal tube, being implemented for structural studies. On the basis of the above-mentioned investigations we disclosed that the course of the blood vessels in membranes of the urinary bladder wall undergoes changes after routine dissection during the cesarean section. There is a disappearance of regular arrangement of the vascular network, particularly in mucous membrane. New vessels of larger calibre with an irregular course are seen to appear throughout the entire width. Such changes were not detected at sites distal to the field of operation. Specimens stemming from the urinary bladders of women, who delivered spontaneously, failed to reveal such changes.
