Between 1979 and 1991, the authors performed 50 psoas bladder ureterovesical reimplantations for lesions of the pelvic ureter. 90% of very good results were obtained with this technique at the cost of a low morbidity. This series confirms the influence of previous pelvic radiotherapy on the postoperative complication rate. On the basis of the excellent results in this series, confirmed by those reported in the literature, this technique can be proposed as treatment of choice for lesions of the pelvic ureter when suture-resection or simple reimplantation cannot be performed after failure of endoluminal dilatation in patients with a life expectancy greater than 6 months to one year.
