Photoselective vaporisation (PVP) of the prostate is being used increasingly to treat symptomatic benign prostatic hyperplasia, due to the associated lower morbidity. Holmium laser enucleation of the prostate was considered to be the treatment with the highest evidence; however, evidence for PVP has dramatically increased recently. ⋯ Perioperative outcomes of catheterisation time and length of hospital stay were shorter with PVP, whereas operative time was longer with PVP. Postoperative complications of blood transfusion and clot retention were significantly less likely with PVP; no difference was noted in other complications. Overall, no difference was noted in intermediate-term functional outcomes.

Randomized Controlled Trial Multicenter Study
Addition of radiotherapy to long-term androgen deprivation in locally advanced prostate cancer: an open randomised phase 3 trial.
Radiotherapy combined with androgen-deprivation therapy (ADT) is superior to radiotherapy alone in localised prostate cancer; however, data comparing ADT alone are somewhat limited. ⋯ Combined therapy strongly favoured improved PFS, locoregional control, and metastasis-free survival. Longer follow-up is needed to assess the potential survival impact.

Randomized Controlled Trial
OnabotulinumtoxinA improves health-related quality of life in patients with urinary incontinence due to idiopathic overactive bladder: a 36-week, double-blind, placebo-controlled, randomized, dose-ranging trial.
Patients with urgency urinary incontinence (UUI) due to overactive bladder (OAB) refractory to oral antimuscarinics have limited therapeutic options. OnabotulinumtoxinA appears to be an effective new treatment. ⋯ A single onabotulinumtoxinA treatment with doses≥100 U resulted in statistically significant and clinically meaningful improvement in HRQOL by week 2 compared with placebo, and this improvement was sustained for ≤36 wk in patients with idiopathic OAB and UUI who were inadequately managed by oral antimuscarinics.

Technetium Tc 99m bone scintigraphy (BS) and contrast-enhanced computed tomography (CT) or magnetic resonance imaging (MRI) of the pelvis and abdomen are universally recommended for detecting prostate cancer (PCa) metastases in cancer of all stages. However, this two-step approach has limited sensitivity and specificity. ⋯ WBMRI outperforms BS/TXR in detecting bone metastases and performs as well as CT for enlarged lymph node evaluation. WBMRI can replace the current multimodality metastatic work-up for the concurrent evaluation of bones and lymph nodes in high-risk PCa patients.

OnabotulinumtoxinA (Onabot/A) has been used to treat detrusor overactivity disorders. The treatment is based on several injections of toxin throughout the bladder wall. However, injection protocols are not well established among clinicians, varying in dose and dilution. ⋯ A single Onabot/A injection spreads the neurotoxin activity to the opposite side of the guinea pig bladder. This action is more evident when high saline volumes are used to dissolve Onabot/A. The toxin cleaves the SNAP-25 protein mainly in cholinergic but also in adrenergic and sensory fibers. In contrast with intramural injection, instillation of Onabot/A does not cleave SNAP-25 in nerve fibers.
