Ureterocele decompression by endoscopic or open incision was the prima
ry treatment in 59 children with 63 ureteroceles. Of these, 18 were in
travesical and 45 were ectopic. The endoscopic or open incision adequa
tely decompressed all intravesical ureteroceles and 37 of 45 ectopic u
reteroceles (82%). After incision, the secondary operation rate was 17
% for intravesical and 62% for ectopic ureteroceles. In our opinion, e
ndoscopic or open incision must be considered a definitive treatment i
n the large majority of intravesical ureteroceles and is also valid in
ectopic ureteroceles. In these cases, the early decompression obtaine
d by this approach produced significant functional recovery, fewer uri
nary tract infections, and facilitated subsequent surgery in those pat
ients requiring complete surgical reconstruction.
