Ureterocalicostomy in the treatment of pyeloplasty failures.

Ureterocalicostomy was performed in 8 patients following failed pyeloplasty: 2 had undergone two previous pyeloplasties, while endourological management had been attempted in 3. With a mean follow-up of 58.7 months, radiographic studies demonstrated resolution of the obstruction in 6 cases (75%), while two kidneys lost their function. The definitive role of endourological techniques after pyeloplasty failure still waits the test of time although they deserve to be applied first, and ureterocalicostomy remains a reliable procedure in this particular setting.
