Trans-pyeloureteric anastomosis in the management of pelviureteric junction obstruction

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.
