Pre-biopsy pelvic phased array dynamic contrast enhanced magnetic resonance imaging is an accurate technique for detecting and quantifying intracapsular transition or peripheral zone tumor foci greater than 0.2 cc. It has promising implications for cancer detection, prognosis and treatment.

OBJECTIVE
To evaluate the early functional outcomes of transurethral plasma vaporization of the prostate (TUVis) in a multicentre study.
PATIENTS AND METHODS
A prospective multicentre observational study was conducted in eight urology departments. The inclusion criterion was benign prostatic hyperplasia (BPH) requiring surgical treatment. Patients on anti‐coagulant therapy were not excluded. The TUVis procedure was performed according to a classic transurethral resection of the prostate (TURP) scheme following the manufacturer’s recommendations. We evaluated subjective functional outcome using self‐questionnaires (International Prostate Symptom Score [IPSS] and five‐item International Index of Erectile Function [IIEF‐5]) and objective criteria (prostate volume, prostate‐specific antigen [PSA], uroflowmetry, post residual volume) at baseline and at 1‐ and 3‐month follow‐ups. All types of complications were systematically recorded.
RESULTS
Despite 52% of patients receiving anticoagulant therapy before surgery, we reported only 3% with haemorrhagic complications, no blood transfusion, a mean catheterization time of 44 h and a mean postoperative stay of 2.9 nights. No significant change in irrigation time, catheter time or hospital stay was observed in patients with or without anticoagulant therapy. The IPSS and bother scores significantly decreased after the 3‐month follow‐up (57% and 59%, respectively), but the average remaining prostate volume was 29 cc and the tissue ablation rate was only 0.5 cc/min. Three major complications occurred, consisting of two urinary fistulas and one partial bladder coagulation.
CONCLUSIONS
The TUVis procedure has a proven fast postoperative recovery time, good short‐term functional outcome and good haemostatic efficiency. However, the tissue ablation rate was lower than expected and we encountered three major complications, the mechanisms of which remain unclear. Considering the high energy level required to create the plasma effect, the generator, cable and resectoscope must be carefully checked before each procedure.
Aims: To establish the clinicopathological features of minimal volume prostate adenocarcinoma on prostate biopsy. Methods: Twenty four cases of minimal adenocarcinoma diagnosed on prostate biopsy and treated by radical prostatectomy were reviewed. Results: The major microscopic criteria were nuclear enlargement (22 of 24), infiltrative pattern (19 of 24), prominent nucleoli (19 of 24), intraluminal eosinophilic secretions (15 of 24), and high grade intraepithelial neoplasia associated (11 of 24). Sixteen of 24 cases were assigned a Gleason score 6 on biopsy. When the whole gland was assessed, 22 of these tumours were localised to the prostate (stage pT2), and only two cases were stage pT3. Conclusions: Minimal focus of adenocarcinoma on prostate biopsy is not an uncommon finding. It is usually an intermediate grade and localised stage neoplasm.
We assessed the therapeutic efficacy and safety of laser prostatectomy (LP) for treating benign prostatic hyperplasia (BPH) in patients on oral anticoagulation. We systematically reviewed previous reports, using the Pubmed database and bibliographies of retrieved articles and reviews. The oral anticoagulation included coumarin derivatives and platelet‐aggregation inhibitors (PAI). Previous studies do not allow the establishment of definitive conclusions for managing patients on oral anticoagulation and who require BPH surgery. No randomized studies are available. Nevertheless, compared to transurethral resection of the prostate (TURP), LP seems to decrease the risk of haemorrhage in patients taking PAI or coumarin derivatives. Therefore, LP is a useful alternative to TURP for managing patients on oral anticoagulation, and could be proposed as the first intention for those patients. Continuing PAI during the procedure is feasible. A replacement of coumarin derivatives by low molecular weight heparin is preferable. No conclusion can be reached on the preferred type of laser technique to treat these patients, but data on laser enucleation is much less abundant and conclusive than that on laser vaporization.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
