OBJECTIVES: To evaluate the results and the place of a minimally invasive intraurethral injection technique designed to improve the efficacy of the urethral sphincter in @entity322 after prostatic surgery. MATERIALS AND METHODS: A prospective study of 26 Macroplastique injections performed in 15 @entity1 with a mean age of 66.4 years (range: 54 to 78 years) was conducted over an 18-month period. Eleven @entity1 received 2 injections. Prostatic surgery consisted of retropubic radical prostatectomy (9 cases), transurethral resection (4 cases) or open prostatectomy (2 cases). Three @entity1 received pelvic irradiation. Evaluation at 1, 3 and 12 months consisted of clinical questionnaire and urodynamic assessment. RESULTS: Rapid deterioration of the initial improvement was observed (40% success at 1 month; 71% at 3 months; 33% at 6 months; 26% at 12 months). No significant influence was demonstrated for post-prostatectomy radiotherapy, the @entity1 's age, more proximal @entity1494 , severity of @entity322 or preoperative status. However, better results were observed when the resting urethral closure pressure remained higher than 30 cm @entity2507 . CONCLUSION: We believe that intraurethral injections still have a place in the therapeutic armamentarium for @entity322 after prostatic surgery with satisfactory initial results, which unfortunately deteriorate after 3 months. Our study confirms the value of Macroplastique compared to other substances. It is difficult to define the predictive factors of failure, but a closure pressure greater than 30 cm @entity2507 remains essential. Finally, an interval of at least 3 months should be observed before repeating this procedure in the case of an insufficient result.
