Ileal conduit undiversion: experience with tunneled vesical implantation of tapered conduit.

Reconstruction of the urinary tract after ileal conduit diversion was done in 9 patients by antirefluxing vesical implantation of the tapered conduit. Of the patients 5 required prior operative rehabilitation of the lower tracts, while 4 had urodynamically normal lower tracts. Reoperation for post-undiversion reflux was necessary in 2 patients; reimplantation was satisfactory in 1 but ileocecocystoplasty was required in the other. Followup showed a stable or improved upper tracts and renal function in the remaining patients.
