Prostate volume estimations using magnetic resonance imaging and transrectal ultrasound compared to radical prostatectomy specimens.

Introduction: We sought to evaluate the accuracy of prostate volume estimates in patients who received both a preoperative transrectal ultrasound (TRUS) and magnetic resonance imaging (MRI) in relation to the referent pathological specimen post-radical prostatectomy.

Methods: Patients receiving both TRUS and MRI prior to radical prostatectomy at one academic institution were retrospectively analyzed. TRUS and MRI volumes were estimated using the prolate ellipsoid formula.

Utilization of pre-operative imaging for colon cancer: A population-based study.

Objective: To assess the use of pre-operative imaging for colon cancer and to identify factors associated with utilization in routine clinical practice.

Methods: This population-based, retrospective cohort study used a random sample of 25% of colon cancer patients treated with surgery in the province of Ontario (2002-2008). Pre-operative imaging (<16 weeks from surgery) of the chest, abdomen-pelvis was identified.

Durable control of locally recurrent renal cell carcinoma using stereotactic body radiotherapy.

Renal cell carcinoma (RCC) is generally poorly responsive to conventional radiation doses, and patients with inoperable local recurrence have limited therapeutic options. Stereotactic body radiotherapy (SBRT) is an increasingly available technology that allows delivery of a radiation schedule providing doses far more biologically effective against cancer cells than conventional radiotherapy. We present a case where durable disease control was achieved using SBRT in a patient with inoperable locally recurrent RCC who presented 18 years from original nephrectomy.

Ectopic drainage of the common bile duct into the lesser curvature of the gastric antrum in a newborn with pyloric atresia, annular pancreas and congenital short bowel syndrome.

We report a newborn with bilious vomiting and the rare combination of pyloric atresia, annular pancreas and ectopic drainage of the common bile duct into the lesser curvature of the gastric antrum. Radiologic, sonographic and percutaneous transhepatic transcholecystic cholangiographic (PTTC) findings, with surgical correlation, are presented.
