New endourologic technique for catheter placement after TURP, prostatectomy, and difficult urethroscopy.

Inserting a Foley catheter into a traumatized urethra with false channels or a post-transurethral resection of prostate (TURP) undermined bladder neck can be very difficult if not impossible at times. Likewise, replacing a Foley catheter that has fallen out in the early postoperative period after a radical prostatectomy can be difficult and can cause significant injury to the fresh anastomosis. We describe a technique using a Peel-Away sheath that fits over a cystoscope or a resectoscope, and facilitates accurate insertion of a Foley catheter without trauma to the urethra.
