Inflammatory myofibroblastic tumor (IMT) is a rare type of mesenchymal tumor, which may affect various organs. The preferential site for IMT in the genitourinary system is the urinary bladder, while the presence of IMT in the kidney, and particularly in the renal pelvis, is rare. In the present report, the case of a 43-year-old man who was admitted to the Department of Urology of The Second Xiangya Hospital of Central South University (Changsha, China) in July 2012, with complaints of iterative gross hematuria and abdominal pain unresponsive to antibiotics is described. Computed tomography and magnetic resonance imaging indicated a slightly enhanced mass in the left renal pelvis of 1.5 cm in diameter. On request of the patient, a left nephrectomy was then performed, based on a suspected diagnosis of renal pelvic carcinoma. However, analysis of the intraoperative fast-frozen section exhibited proliferation of compact spindle cells, suggesting IMT. Therefore, further ureterectomy was avoided, and the patient remained in healthy condition thereafter.

Urothelial carcinoma (UC) can arise from either the lower urinary tract or the upper tract; they represent different disease entities and require different clinical treatment strategies. A full understanding of the cellular characteristics in UC may guide the development of novel therapies. Here, we performed single-cell transcriptome analysis from four patients with UC of the bladder (UCB), five patients with UC of the ureter (UCU), and four patients with UC of the renal pelvis (UCRP) to develop a comprehensive cell atlas of UC.

Fibroepithelial polyps are rare benign tumors originating from the mesoderm and are more commonly found in the renal pelvis and distal ureter and less frequently in the proximal ureter or bladder. This case report presents a fibroepithelial polyp occurring in the bladder of the fetus, showcasing its two-dimensional ultrasound, three-dimensional ultrasound, color Doppler, and spectral Doppler ultrasound findings, providing a reference for the accurate diagnosis of this condition.

The aim of the present study was to determine the prognostic significance of a novel marker, the red cell distribution width to lymphocyte percentage (RDW-to-LYM%) ratio, in patients with upper tract urothelial carcinoma (UTUC) after radical nephroureterectomy (RNU). The clinical and follow-up data of 625 patients with UTUC receiving RNU were retrospectively analyzed. The optimal cut-off value of the pre-treatment RDW-to-LYM% ratio was determined as 0.

History A 65-year-old male patient with a history of sarcomatoid renal cell carcinoma and prior right nephrectomy developed recurrent disease adjacent to the inferior vena cava. The patient underwent surveillance imaging 7 months after initiation of treatment with maximum-dose pazopanib and less than 1 month after completing a 2-month regimen of palliative stereotactic body radiation therapy to the right nephrectomy bed and site of recurrence. (Stereotactic body radiation therapy was initiated 5 months after pazopanib treatment was initiated.

The primary objective of urolithiasis therapy is complete stone removal and highest stone-clearance rates possible to minimize recurrence. A novel approach that employs a magnetic suspension and a magnetic probe for the passive collection and removal of small residual fragments was developed. This study assessed the feasibility of this system in porcine models.
