A 55-year-old man underwent right partial nephrectomy and was diagnosed with papillary type 1 renal cell carcinoma (RCC), pT1a. The surgical margin was negative. Six months later, a follow-up computed tomography scan revealed that a mass appeared adjacent to the location of resection. There were no symptoms nor abnormal blood chemistry results at that time. The possibility of local recurrence of RCC could not be ruled out with by magnetic resonance imaging. Radical nephrectomy was performed for suspected rapid recurrence of RCC. Pathological diagnosis was xanthogranulomatous pyelonephritis but not malignancy.

Adrenal capillary hemangiomas are an extremely rare tumor type, and no previous studies have described their features using dynamic contrast-enhanced computed tomography. We report the case of a 65-year-old male patient with a history of right partial nephrectomy for renal clear cell carcinoma. During follow-up, computed tomography scans revealed growth of a right adrenal nodule.

Background: Peritoneal recurrence (PREC) following nephrectomy for localized renal cancer (RCC) is rare. Our objective was to report a multicenter analysis of PREC to analyze incidence, treatment, survival and risk factors.
Methods: Between 1987 and 2023, patients with PREC following radical or partial nephrectomy (PN) for localized RCC across ten European institutions (UroCCR, NKI, IRCCS, Foch and Gustave Roussy centers) were included.

The evaluation and management of renal masses, predominantly of the clear cell renal cell carcinoma subtype, have been evolving over the past several years and demanding greater attention from nephrologists. Oncologic survival of localized tumors approaches 100%, where survival is more closely tied to underlying comorbidities including chronic kidney disease (CKD). Early diagnosis and thus increasing prevalence related to incidental discovery of renal masses allows greater emphasis on nephron-sparing procedures and for residual kidney function preservation.

Simultaneous resection for multiple tumors with RAPN is complicated and challenging. Herein, we report the successful resection of three synchronous renal tumors located in unilateral kidney with RAPN using the hinotori surgical robot system.

Case Presentation: A 77-year-old male with urothelial carcinoma with trophoblastic differentiation underwent robot-assisted radical cystectomy following neoadjuvant chemotherapy. Pathological examination revealed urothelial carcinoma, classified as ypT2b and ypN0 with detection of focal hCGβ positivity.
