Purpose: A new technique using an everting suture to construct a urete
ral nipple is described. Materials and Methods: The method was used to
create 28 ureteral nipples. A 2-zero silk suture is passed through th
e ureteral wall, transfixing the lumen, and is tied 5 cm. away from th
e ureteral wall. The ends are cut 10 cm, long. The suture is grasped w
ithin the ureteral lumen and with traction the ureter is everted in 1
step without trauma. Results: The suture resulted in smooth 1-step atr
aumatic eversion of the ureter in all cases. Conclusions: With this te
chnique a well formed nipple of the desired length can be constructed.
