What's known on the subject? And what does the study add? We have previously shown that percutaneous radiofrequency ablation guided by image-fusion technology allows for precise needle placement with real time ultrasound superimposed with pre-loaded imaging, removing the need for real-time CT or MR guidance. Emerging technology also allows real-time tracking of a treatment needle within an organ in a virtually created 3D format. To our knowledge, this is the first study utilising a sophisticated ultrasound-based navigation system that uses both image-fusion and real-time probe-tracking technologies for in-vivo renal ablative intervention. ⋯ • Percutaneous renal RFA guided exclusively by real-time 2D US with multiplanar Global Positioning System-like probe tracking is feasible and accurate. • Near-future technologies, including elastic fusion overlay and anticipation of soft-tissue deformation, will further augment this guidance system.

What's known on the subject? and What does the study add? Priapism is a rare event. However, various medications and medical conditions may increase the risk. Priapism can be ischaemic, non-ischaemic or stuttering. It is paramount to distinguish the type of priapism, as misdiagnosis may lead to significant morbidity. Ischaemic priapism represents a compartment syndrome of the penis and is therefore a medical emergency. A delay in management may significantly affect future erectile function. Stuttering priapism represents recurrent subacute episodes of ischaemic priapism, which may lead to erectile dysfunction. Thus episodes must be minimised. Non-ischaemic priapism is not a medical emergency. However, misdiagnosis and injection with sympathomimetic agents can result in system absorption and toxicity. This review article provides a summary of the evaluation and management of priapism. Furthermore, a step by step flow chart is provided to guide the clinician through the assessment and management of this complex issue. ⋯ Priapism is a complex condition that requires expert care to prevent complications and irreversible erectile dysfunction.

Comparative Study
Use of a mixture of lignocaine and bupivacaine vs lignocaine alone for male circumcision under local anaesthesia in Rakai, Uganda.
To assess self-reported pain control during and after surgery with a mixture of lignocaine and bupivacaine compared with lignocaine alone among male circumcision (MC) service recipients in Rakai, Uganda. ⋯ The LBmix significantly reduced pain associated with MC and the need for additional anaesthesia during MC.

From 2007 to date, fi ve boys with bladder exstrophy underwent this pre-emptive treatment of inguinal hernia at our institution. None has developed a recurrence after a median (range) follow-up of 29 (5 – 46) months. ⋯ Furthermore, the presence of a pelvic diastasis makes the pelvic dissection of the cord easier than in normal children with a closed pelvic ring. The same procedure can also possibly be performed in children with a congenital inguinal hernia undergoing other procedures that require dissection of the perivesical space, e.g. ureteric re-implantation or ureterocoele repair.

Comparative Study
Cost-effectiveness analysis of degarelix for advanced hormone-dependent prostate cancer.
To evaluate the cost-effectiveness of degarelix vs luteinizing hormone-releasing hormone analogue (triptorelin) plus short-term antiandrogen treatment for advanced prostate cancer. ⋯ Degarelix is unlikely to be cost-effective compared to triptorelin plus short-term antiandrogen in the management of advanced prostate cancer with respect to the usual thresholds of cost-effectiveness used in the UK: £20,000-30,000 per QALY gained (used by the National Institute for Health and Clinical Excellence).
