[Endoscopic transvesicoparietal exteriorization of ureteral catheters]. / Extériorisation transvésicopariétale endoscopique des sondes urétérales.

ABSTRACT

Endoscopic introduction of catheter into the ureter for drainage has long been a common procedure, and recent advances in endoscopic urology have widened its indications. The ureteral catheter is usually exteriorized through the urethra and attached to the urethral catheter, but with this technique it tends to descend spontaneously and to create infections which are a possible cause of ureteral stenosis. A technique of endoscopic transvesicoparietal exteriorization of ureteral catheters without incision has been developed in 1982. The problems encountered in exteriorizing the ureteral catheter through the lumen of a suprapubic trocar have now been solved by using a bipodal forceps introduced into the trocar.
