Pyelovesicostomy: an alternative to ureteropelvic junction-plasty in pelvic ectopic kidneys.

Pyelovesicostomy was performed in 2 cases of hydronephrosis in pelvic kidneys secondary to ureteropelvic junction obstruction. In the first patient, who presented with a solitary kidney, the procedure was done after failure of a dismembered pyeloplasty, while in the second patient the procedure was performed electively. Both patients had sterile urines and stable renal function, although some dilatation persisted in the first case. The indications and the functional aspects of this surgical solution are discussed.
