New technique for antegrade collagen injection for post-radical prostatectomy stress urinary incontinence.

摘要

A new modification for antegrade collagen injection into the bladder neck is described. A 16F Rusch suprapubic catheter is used to access the bladder. A 15.5F Storz cystoscope is then placed through the sheath and the collagen injection needle is then placed through the cystoscope in the usual manner. This technique permits more rapid bladder access with less bleeding and leakage of irrigation fluid than using guide wires and Amplatz dilators.
