Pelvioplasty--patient selection

An ever-increasing number of modalities provide diagnostic and predictive indicators for better patient selection in the treatment of ureteropelvic juncture obstruction. Contemporary histological studies and improved results have culminated in the selection of the dismembered pelvioplasty as the operation of choice. When the renal scan, renogram, renal biopsy or nitroblue tetrazolium studies are used fewer patients are subjected to a needless reconstructive operation. Dismembered pelvioplasty provides excision of the diseased ureter, reduction of pelvic redundancy and an opportunity for the "pacemaker" cells to function properly.
