ReviewImplications of pacemakers and implantable cardioverter defibrillators in urological practice.
Pacemakers and implantable cardioverter defibrillators are widely used and often encountered in urology practices worldwide. Safety and performance during electrosurgery, extracorporeal shock wave lithotripsy, magnetic resonance imaging, positron emission tomography and radiotherapy are not clearly defined. We reviewed the literature on their use and implications in urological practice. ⋯ Clear guidelines are essential given the rapid advances in technology to enhance patient safety. Magnetic resonance imaging should be avoided in patients without a magnetic resonance imaging compatible device. However, patients can undergo extracorporeal shock wave lithotripsy, radiotherapy and positron emission tomography as long as the device is not in the path.

Comparative StudyPhysiological changes in transperitoneal versus retroperitoneal laparoscopy in children: a prospective analysis.
The choice of minimally invasive surgical approaches in pediatric urology is largely influenced by surgeon preference and experience. Little is known about the differences in physiological variables that might objectively influence the choice of surgical approach. We compared the cerebral and systemic hemodynamic effects of transperitoneal vs retroperitoneal CO(2) insufflation in children. ⋯ Cerebral blood flow velocity and end tidal CO(2) seem to increase progressively and gradually during retroperitoneal laparoscopy, in contrast to the more rapid increase and plateau effect during transperitoneal laparoscopy. Presumably the smaller absorptive surface in the retroperitoneal space explains this physiological difference.

Acute versus chronic exposure to androgen suppression for prostate cancer: impact on the exercise response.
Exercise has been proposed as an effective countermeasure for androgen suppression therapy induced side effects. Since the magnitude of fat gain and muscle loss is most pronounced during the early phases of androgen suppression therapy, the exercise response may differ by the duration of androgen suppression therapy. We investigated whether the exercise response varied by the prior duration of exposure to androgen suppression therapy, that is acute--less than 6 months vs later--6 months or greater. ⋯ Apart from differences in body fat and triglycerides the beneficial effects of exercise are similar in patients on acute or chronic androgen suppression therapy.

Face, content and construct validity of a novel robotic surgery simulator.
We evaluated the face, content and construct validity of the novel da Vinci® Skills Simulator™ using the da Vinci Si™ Surgeon Console as the surgeon interface. ⋯ We confirmed the face, content and construct validity of a novel robotic skill simulator that uses the da Vinci Si Surgeon Console. Although it is currently limited to basic skill training, this device is likely to influence robotic surgical training across specialties.

Expanded prostate cancer index composite for clinical practice: development and validation of a practical health related quality of life instrument for use in the routine clinical care of patients with prostate cancer.
Measuring the health related quality of life of patients with prostate cancer in routine clinical practice is hindered by the lack of instruments enabling efficient, real-time, point of care scoring of multiple health related quality of life domains. Thus, we developed an instrument for this purpose. ⋯ The Expanded Prostate Cancer Index Composite for Clinical Practice is a valid instrument that enables patient reported, health related quality of life to be measured efficiently and accurately at the point of care, and thereby facilitates improved emphasis and management of patient reported outcomes.
