DW MR imaging allows monitoring of antiandrogen therapy in bone metastases. PSA level decrease corresponded well with an increase in mean tumor ADC. Heterogeneity of tumor response to therapy was demonstrated by functional DM analysis.

In the present study, the AirSeal Trocar offered a more stable pneumocavity and facilitated specimen retrieval and needle extraction.

The results of the current evaluation underline the clinical advantages of an extraperitoneal approach for RARP. However, a transperitoneal approach is still considered necessary for extended LND or special clinical conditions. Robotic teams should be trained using both approaches.

Introduction Penile constriction rings are either used for autoerotic stimulus or to increase sexual performance. Potentially, they can become irremovable and cause urologic emergencies. Aim We describe the successful removal of a 3.6-cm long piece of heavy metal tubing used as a penile constriction ring. Methods An angel grinder was used to open the metal tubing on both lateral sides. During the cutting procedure, the soft tissue parts were protected by two metal spatulas. Wet towels and cool running water prevented thermal injury. Results After removal of the band, no iatrogenic injury was visible and the further recovery of the patient remained uneventful. Postoperatively, one of the surgeons suffered from conjunctivitis of the left eye possibly due to metal sparks. Conclusion Depending on the constricting object, heavy-duty technical equipment might become necessary for their removal. In such cases, special care should be taken to avoid injury to the patient and the medical crew.

The buried penis syndrome in adults is a rare condition of different aetiologies. Today extreme obesity is considered as a major contributor. We present a case of a 30-year-old extremely obese patient (BMI 65 kg/m(2)) with purulent infection of the penile cavity, a phlegmon of the mons pubis and urinary retention due to a buried penis. Whereas acute complications of a buried penis in obese patients include local infection and urinary retention, chronic problems are undirected voiding, disturbed vaginal penetration and erectile dysfunction. Even though several surgical techniques are described, weight reduction should be primarily preferred.
