The diagnostic utility of diffusion weighted MRI imaging and ADC ratio to distinguish benign from malignant renal masses: sorting the kittens from the tigers.

Background: MRI is playing an increasing role in risk stratification and non-invasive diagnosis of the undifferentiated small renal mass. This study was designed to assess the reliability of MRI in diagnostic evaluation of renal masses, specifically characterising lesions with diffusion weighted imaging (DWI) and apparent diffusion coefficient (ADC) values.

Methods: This is a retrospective analysis of patients undergoing MRI as part of their clinical workup for a renal mass suspicious for renal cell carcinoma (RCC) on CT or ultrasound followed by biopsy and/or surgical excision.

Bladder perforation: A rare complication of retention management.

A healthy 25 year old woman presented with acute urinary retention following alcohol ingestion. A 14 french foley catheter drained over 1 L of haematuria immediately. Due to worsening and persistent abdominal pain, CT and ultrasound imaging was performed, demonstrating only a small amount of free fluid.

Novel approach to locating a hypoplastic kidney in a unique variant of uterine didelphys syndrome presenting with continuous incontinence.

Mullerian abnormalities such as uterine didelphys have an association with renal abnormalities. Ureteric ectopia must be considered as a differential diagnosis of incontinence. We describe the case of a 21-year-old woman who presented with low volume continuous incontinence with a history of right renal agenesis and uterus didelphys.
