5. A method of performing anastomosis following radical prostatectomy comprising the steps of:
-
a. providing a urethral catheter 200 comprising i. a catheter body constituting a telescopic structure further comprising inner and outer members;
said inner member is provided at a distal end thereof with an inflatable anchoring balloon adapted for fixating said bladder neck;
said outer member includes a plurality of apertures on a side of said member thereof;ii. a remotely controlled needle assemble comprising a plurality of needle;
an extremity of each said needle is positioned at said corresponding aperture and adapted for directing outward through said aperture and an adjacent tissue;iii. a plurality of U-shaped sutures having two ends;
each first end thereof is releasably connected to an distal extremity of corresponding said needle;
