[Surgical and pathological consequences of preoperative immunotherapy in onco-urology].

Introduction: Patients treated with immunotherapy might need surgical procedures in addition to the medical treatment. The main indications are cytoreductive nephrectomy, cystectomy (as part of clinical trials) and metastasis removal in some oligometastatic patients. This study aims to assess the feasibility of surgery for patients treated by immunotherapy and describes the histological modifications found in the pathological analysis.

Prospective Comparison of Thulium and Holmium Laser Lithotripsy for the Treatment of Upper Urinary Tract Lithiasis.

Background: Lithotripsy with holmium:yttrium-aluminum-garnet (Ho:YAG) laser is the current gold standard for treating stones of the upper urinary tract (UUT). The recently introduced thulium fiber laser (TFL) has the potential to be more efficient and as safe as Ho:YAG.

Objective: To compare the performance and complications between Ho:YAG and TFL for UUT lithotripsy.

Angiomyxoma of the ureter imitating an upper tract urothelial carcinoma: A case report.

Introduction: Angiomyxomas are rare benign neoplasms of mesenchymal origin arising from the soft tissues of the perineum and pelvis.

Case Presentation: To our knowledge, we report the first case of ureteral angiomyxoma arising de novo in a fifty-four-year-old female patient who presented with macroscopic hematuria.

Discussion: The pathological findings, radiological features and operative management will be discussed.
