Ureterocalicostomy for reconstruction of complicated pelviureteric junction obstruction.

Seven patients with complicated pelviureteric junction (PUJ) obstruction underwent reconstruction by means of ureterocalicostomy; 5 had undergone previous surgery and 2 had primary obstruction. Radiographic studies showed resolution or improvement of the obstruction in 5 patients, who remain asymptomatic 15 to 47 months (mean 30) post-operatively. Obstruction persists in 1 patient and the other developed renal artery thrombosis with subsequent loss of the kidney. It was concluded that ureterocalicostomy can provide long-term, successful reconstruction of a complicated PUJ obstruction, but significant complications may be associated with the procedure.
