Collecting duct carcinoma (CDC), which is also known as Bellini duct carcinoma, accounts for less than 1% of all renal cell carcinoma, which has a poor prognosis. Predominantly, clinicians recognize this disease due to past experience and case reports, and a standard treatment is yet to be established. The present case report describes a 57-year-old male patient with CDC who was successfully treated with a left laparoscopic radical nephrectomy without any adjuvant therapy and compares the present patient's clinical presentation with previously reported cases...

BACKGROUND: Robotic single-site retroperitoneal renal surgery has the potential to minimize the morbidity of standard transperitoneal and multiport approaches. Traditionally, technological limitations of non-purpose-built robotic platforms have hindered the application of this approach. OBJECTIVE: To assess the feasibility of retroperitoneal renal surgery using a new purpose-built robotic single-port surgical system. DESIGN, SETTING, AND PARTICIPANTS: This was a preclinical study using three male cadavers to assess the feasibility of the da Vinci SP1098 surgical system for robotic laparoendoscopic single-site (R-LESS) retroperitoneal renal surgery...

Primary renal carcinoid tumors are exceedingly rare, with less than 100 total cases being documented in world literature. A 32-year old male was referred to our service for a slow-growing, renal mass, which was first diagnosed 9-years prior. The patient was successfully treated with radical nephrectomy. In this article, we present our case report on an asymptomatic primary renal carcinoid tumor.

Ureter tumor thrombus (TT) of renal cell carcinoma (RCC) is quite rare, although RCC-TT in the inferior vena cava (IVC) is not uncommon. We report the first case of RCC-TT extending into the IVC and ovarian vein as well as the ureter. Neoadjuvant axitinib shrank both the primary tumor and TT, making radical nephrectomy less invasive, particularly by downleveling the IVC-TT. Pathological examination of the primary tumor, IVC-TT, and ureter TT showed clear cell carcinoma with extensive necrosis. Although the role of neoadjuvant axitinib in RCC remains unclear, the present case suggests that neoadjuvant axitinib is clinically beneficial for RCC-TT...

Solitary fibrous tumor (SFT) of the kidney is a rare entity and usually displays a favorable prognosis. We herein report a second case of renal SFT developing local recurrence. A 50-year-old man was referred to our hospital because of a left renal mass. An abdominal CT detected a large renal tumor and radical nephrectomy was performed with a possible diagnosis of renal cell carcinoma. The resected tumor size was measured at 17 × 11 × 8 cm. Grossly, necrosis was observed in central lesion of the tumor but hemorrhage was not observed...

PURPOSE: Due to the widespread use of computerized tomography, the diagnosis of small renal cancers (3 cm or less) within the T1a classification continues to increase. Current treatment of these tumors includes radical nephrectomy, partial nephrectomy and thermal ablation. We used the SEER (Surveillance, Epidemiology, and End Results) Program to compare treatment modalities for these cancers based on 1 cm increments in tumor size. We examined overall survival, cancer specific survival, survival from cardiovascular disease and race based treatment disparities...
