To assess the correlation between intratesticular pressure (ITP) after testicular torsion and subsequent testicular function using a rat model and to show that ITP at surgery is a useful predictor of future spermatogenesis. ⋯ A smaller reduction in ITP after detorsion can be a risk factor for subsequent disturbance of spermatogenesis, suggesting that ITP can be an index for determining whether the affected testis should be removed after testicular torsion.

Randomized Controlled Trial Multicenter Study Comparative Study
Results from an international multicentre double-blind randomized controlled trial on the perioperative efficacy and safety of bipolar vs monopolar transurethral resection of the prostate.
To compare the perioperative efficacy and safety of bipolar (B-) and monopolar transurethral resection of the prostate (M-TURP) in an international multicentre double-blind randomized controlled trial using the bipolar system AUTOCON(®) II 400 ESU for the first time. ⋯ In contrast to the previous available evidence, no clinical advantage for B-TURP was shown. Perioperative efficacy, safety and secondary outcomes were comparable between study arms. The potentially improved safety of B-TURP that is attributed to the elimination of dilutional hyponatraemia risk, a risk still present with M-TURP, did not translate into a significant clinical benefit in experienced hands.

Randomized Controlled Trial Multicenter Study
Can simvastatin improve erectile function and health-related quality of life in men aged >40 years with erectile dysfunction? Rationale and design of the Erectile Dysfunction and Statins (EDS) Trial [ISRCTN66772971](1).
What's known on the subject? and What will the study add? Erectile dysfunction is often associated with endothelial dysfunction. It is also recognized as a marker for underlying vascular disease. This study tests the hypothesis that statin therapy may improve erectile function and also reduce the risk of future cardiovascular events via a reduction in serum cholesterol and by improving endothelial function. The study will also determine whether the treatment improves quality of life related to sexual function. ⋯ • If simvastatin improves erectile function it would provide an inexpensive treatment for ED suitable for most men, and reduce the risk of future CVD.

What's known on the subject ? and What does the study add? The treatment of younger men with testicular germ cell cancers is well documented with established intensive chemotherapy regimens for those with advanced disease. Although the majority of patients present in the third or fourth decade, men also present in later life. These patients are typically excluded from clinical trials and there are no contemporary published series describing their management. This series describes the management of older patients with testicular germ cell tumours at both early and advanced stages of disease. Patients with stage I seminoma can be safely managed with all recognised treatment strategies and state I non-seminomas were managed with surveillance. Cure can still be achieved in older patients with advance germ cell tumours however chemotherapy regimens developed in younger patients must be tailored to the presence of co-morbidity. ⋯ • In elderly patients, GCC should be managed with curative intent. • Conventional therapies are tolerable for most men with stage I seminoma. In metastatic disease, comorbidity may necessitate treatment modifications. • Most patients are cured with manageable toxicity.

What's known on the subject ? and What does the study add? Transrectal High-Intensity Focused Ultrasound (HIFU) ablation has been used as a minimally invasive treatment for localized prostate cancer for 15 years. Five-year disease-free survival rates of 66-78% have been reported, challenging the results of external-beam radiation therapy. Usually, a 6-mm safety margin is used in the apex to preserve the urinary sphincter and potency. The influence of this 6-mm margin on the results of the treatment has never been assessed. This retrospective study of a cohort of 99 patients who underwent systematic biopsy 3-6 months after HIFU ablation for prostate cancer (with a 6-mm safety margin in the apex) shows that post-HIFU residual cancer is found more frequently in the apex. Therefore, new strategies improving the prostate destruction at the apex while preserving the urinary continence need to be found. ⋯ • When a 6-mm apical safety margin is used, residual cancer after HIFU ablation is found significantly more frequently in the apex.
