“…'3 Ultrasonography, however, is at a disadvantage compared with urography in that the normal ureter is not identified and the anatomical detail obtained of the renal pelvis is inferior. Urothelial tumours of the upper urinary tract are rare compared with bladder tumours,'4 15 and none were encountered in our series. Most ureteric tumours present with upper tract dilatation, which would be identified by ultrasonography and indicate the need for further investigation.…”

“…The prognosis of patients with these tumors has repeatedly been shown to depend on the tumor stage and grade. [9][10][11][13][14][15][17][18][19][21][22][23][24] At nephrectomy, our study group was divided nearly equally into those with noninvasive disease and those with an invasive component ( Table 2). Nielsen and Ostri 21 in their study of primary tumors of the renal pelvis had a slightly greater percentage (56%) of noninvasive tumors.…”

“…5 In certain regions of the world, and in patients with certain tubulointerstitial nephritides, the incidence of urothelial neoplasms of the renal pelvis and ureter is quite high, with renal pelvic carcinoma accounting for as much as 68% of renal tumors in some series. 4,6 As a result of the general scarcity of these tumors, [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24] coupled with the even lower incidence of ureteral urothelial tumors (1% of urothelial neoplasms), 2 a large proportion of published reports incorporate tumors at both sites into single studies. There have been few analyses of renal pelvic urothelial neoplasms recently in the pathology literature.…”

Impact of the 1998 World Health Organization/International Society of Urological Pathology classification system for urothelial neoplasms of the kidney

The classification of urothelial neoplasms of the kidney traditionally has been similar to that of urinary bladder tumors. Several years ago, the classification of papillary urothelial neoplasms was revised. The current study focuses on the application of the 1998 World Health Organization (WHO)/International Society of Urological Pathology classification system to 102 renal pelvic urothelial neoplasms and compares it to the 1973 WHO classification scheme. In this study, all tumors were classified as urothelial carcinomas, and the majority (85%) were papillary. Most patients with papillary tumors presented with 'superficial' disease (rpT1). With the 1998 system, most papillary carcinomas were high grade, and were more often invasive as compared to low-grade tumors. Only 34% were low-grade papillary tumors and, of these, most (93%) were noninvasive. With the 1973 system, most papillary tumors were grade 2 or 3, with invasion more common in grade 3 tumors. By 1973 criteria, grade 2 tumors were a heterogeneous group; with 1998 criteria, nearly one-half were high grade and the other half low grade. The grade of papillary urothelial carcinomas with both the 1973 and 1998 grading methods was associated with stage (P ¼ 0.001). Our study reveals that papillomas and papillary urothelial neoplasms of low malignant potential are uncommon tumors in the kidney. Renal pelvic papillary urothelial neoplasms are most often carcinomas and are more commonly high grade than low grade. Although both the 1973 and 1998 systems showed a significant association with tumor stage, grade 2 papillary carcinomas are a heterogeneous group by 1973 criteria. The 1998 system provides useful information in that it more clearly defines a papillary tumor's grade and selects for a group of tumors, namely low-grade papillary urothelial carcinomas, for which a low likelihood of invasion can be predicted.

“…Compared with the ratio of 30-50:2-5:1 for tumors originating from cysts, pelves and ureters in ureteral epithelial carcinoma, ureteral involvement is distinctively higher in malignant mesodermal mixed tumor [15,16]. In addition, the lower ureter is more frequently involved in cases of malignant mesodermal mixed tumors (6/7; 65.7%) than in ureteral epithelial carcinoma.…”

Malignant mesodermal mixed tumor comprised of epithelial and nonepithelial components is rarely encountered in the urological field. Only 6 cases of malignant mesodermal mixed tumor of the ureter have previously been reported in the literature. We recently encountered a 7th case of malignant mesodermal mixed tumor of the ureter and describe the case in detail. The etiology of malignant mesodermal mixed tumor is also discussed.
