Ureterocystoplasty for megaureter: a technique practicable in bladder wall fibrosis.

The cause of megaureter (hydroureter) is inadequacy of the ureterovesical junction. The only possible means of its therapy consists in a surgical reconstruction of the ureterovesical junction. A technical modification of ureterocystoplasty for megaureter, having been employed since 1976, is described. It basically consists in the construction of a tunnel from the ureter within the bladder, the ureter being sutured to the wall of the bladder only loosely. In 150 children 182 ureteroneocystoplastic operations were done. As confirmed by the postoperative course, as well as by the results of the follow-up studies, the technique may be used with benefit even in case of infection, impaired renal function or bladder wall fibrosis.
