Background: The application of pyeloureteric anastomoses in the management of pelviureteric junction obstruction is described.
Methods: Two patients, one requiring a ureterocystoplasty for bladder augmentation but with a coexistent contralateral pelviureteric junction (PUJ) obstruction and the other with gross hydronephrosis but an atretic ipsilateral ureter, underwent trans-pyeloureteric anastomosis to relieve the obstruction.
Results: Both patients demonstrated satisfactory drainage of the upper tracts on postoperative imaging.
Conclusions: Transureteropyeloplasty represents a novel and valid technique of urinary tract reconstruction in complex cases of PUJ obstruction.
