Perivascular epithelioid cell neoplasm (PEComa) of the urinary bladder presenting as urinary tract infection in a young woman.

PEComa is a rare mesenchymal tumor with unique features, sometimes manifesting in younger patients and can exhibit malignant transformation. We present a 24-year-old woman with urinary symptoms and hematuria. Imagining revealed a protruding mass in the bladder dome, raising suspicion for adenocarcinoma due to its location and vascular appearance.

Ramadan fasting and rates of admissions for renal colic due to urolithiasis: a retrospective case-control study.

Objective: The impact of Ramadan fasting on the prevalence of renal colic (RC) remains controversial. This current study aimed to assess the correlation between Ramadan fasting, prevalence of RC and the rate of urgent endoscopic interventions due to urolithiasis.

Methods: This retrospective case-control study enrolled adult patients with a primary diagnosis of RC secondary to urolithiasis admitted to the emergency department during the years 2009-2019.

Lower and upper urinary tract urothelial carcinoma in crossed fused ectopic kidney.

Urothelial tumors in patients with anatomical abnormalities may pose significant challenges. Management follows the same principles which are employed in normal anatomy, however, thorough diagnostic investigation is warranted in order to delineate key anatomical landmarks. Meticulous pre-operative investigation should utilize every imaging modality which can assist the surgeons.

Role of clinicopathological variables in predicting recurrence and survival outcomes after surgery for non-metastatic renal cell carcinoma: Systematic review and meta-analysis.

Renal cell carcinoma (RCC) represents 2% of all diagnosed malignancies worldwide, with disease recurrence affecting 20% to 40% of patients. Existing prognostic recurrence models based on clinicopathological features continue to be a subject of controversy. In this meta-analysis, we summarized research findings that explored the correlation between clinicopathological characteristics and post-surgery survival outcomes in non-metastatic RCC patients.
