Upper urinary tract calculi with infection is a quite difficult acute urologic emergency. And what is more, upper urinary tract obstruction after radical cystectomy following urinary diversion may be fatal in the vulnerable patients with this kind of situation. Postoperative anatomy and other factors affect the upper urinary tract calculi, and urinary tract infection greatly increased the risk. But it is particularly difficult to handle with patients with poor general condition and septic shock treatment, so how to optimize the selection program is worth further studying...

Lymphangioma is a rare, benign mesenchymal neoplasm, which is characterized by numerous intercommunicating cystic spaces containing lymphatic fluid. It is considered a congenital disease resulting from the obstruction of regional lymph drainage during the developmental period. Lymphangioma frequently occurs in the cervical neck and axilla, also in the retroperitoneum, mediastinum, mesentery, omentum, colon, and pelvis, rarely in the perirenal space. These tumors usually present in childhood, but infrequently, these also present in adults...

Urothelial carcinomas span the bladder, ureter, and renal pelvis, and while there had been stagnation in the field of drug approval for the past two decades, there is now accelerated and regular US FDA approval of 5 immunotherapy agents. However, patients who inherently do not respond or progress on such therapies still represent an area of increased unmet need. In this special Seminars issue, we explore varying aspects of bladder urothelial carcinoma treatment with targeted therapies, the unique presentation and challenges in the treatment of upper tract and renal pelvis tumors, as well as new and emerging diagnostic imaging tools for varying genitourinary cancers...

The simultaneous occurrence of renal cell carcinoma (RCC) and urothelial carcinoma (UC) in the same kidney is extraordinarily rare, and is also known as multiple primary malignant tumors. The present study reports the case of a 76-year-old female with synchronous ipsilateral RCC and UC of the renal pelvis, who underwent operation, chemotherapy and reoperation when recurrence of RCC or UC was identified. Cluster of differentiation 44 (CD44) is one of the promising markers for identifying cancer stem cells in various solid tumors, along with aldehyde dehydrogenase 1 A1 (ALDH1A1)...

Diagnosis of upper urinary tract urothelial carcinoma in ureteroscopic biopsies is challenging. Therefore, an immunohistochemical marker that can differentiate between malignant and benign urothelium and predict final pathological features is necessary. In this study, we investigated Ki-67 expression in 26 ureteroscopic biopsies of the ureter and renal pelvis diagnosed with urothelial carcinoma (UC) and in 13 biopsies with non-neoplastic urothelium, using digital image analysis. The median Ki-67 labeling index was 1...

Spontaneous nephroblastoma is an uncommon tumor in laboratory rabbits. We recently encountered this tumor, and we describe its histological characteristics in this report. A male 3-year-old Japanese White rabbit (JW/kbs), maintained as a stock animal, suddenly showed poor condition and was found dead a few days later. At necropsy, a large mass was found that extended from one side of the renal pelvis. The cut surface of the mass was dark red in color and velvety to the touch. The kidney on the contralateral side was normal...
