A 5-year retrospective study of 131 hematuria patients (23 with gross and 108 with microscopic hematuria) undergoing retrograde pyelography solely for fractional visualization of the upper tracts on excretory urography revealed no tumors or other significant pathological condition in the 187 renal units (56 bilateral cases) studied. A review of our cases of upper tract urothelial cancer since 1955 revealed 36 patients with complete records of the urological evaluations. None of the cases was diagnosed by retrograde pyelography for fractionally visualized excretory urography and 3 were within 9 months of a previously normal excretory urogram alone or with retrograde pyelography. We believe that retrograde pyelography done solely to evaluate a fractionally visualized upper tract may miss subtle lesions and it should not terminate the evaluation. We recommend that excretory urography, cystoscopy and voided urine cytology studies be performed initially and, if normal, they should be repeated in 6 and 12 months before upper tract urothelial tumors are ruled out.
