RESUMEN
INTRODUCTION: Preservation of the testicle is directly associated with the duration of torsion. The aim in this retrospective study was to identify factors that influence pre-and in-hospital times and measure the extent to which these times affect testicle survival. PATIENTS AND METHODS: A retrospective review of 116 patients who underwent exploration for testicular torsion between 2000 and 2015. Patients were divided into orchiectomy and salvaged testicle groups. Times in patient management and clinical features were compared with Mann-Whitney, chi-squared, and Fisher exact tests. Multivariate logistical regression was used to identify independent factors associated with orchiectomy. RESULTS: The median prehospital time of 48 h (15.4-138 h) in the orchiectomy group was longer than the 2.4 h (1.6 h-5.2h) in the salvaged group. Patients examined by a general practitioner (GP) prior to presenting at hospital had a median prehospital time of 48 h, compared to 3 h for patients not examined before presentation at hospital. In-hospital times between admission and operation room, as well as times between ultrasonography and operation room, were also longer in the orchiectomy group. Previous GP consultation (OR = 27.26, 95% CI 2.32-320.59, p = .009), prehospital time (OR = 1.04, 95% CI 1.01-1.07, p = .003) and nausea (OR = 9.25, 95% IC 1.33-64.52, p = .025) were independent predictive factors associated with orchiectomy. CONCLUSION: Prehospital time was a determining factor in orchiectomy. For each extra hour of prehospital delay, the risk of orchiectomy increased by 4%. The rate of orchiectomy was higher among patients who first consulted a GP.

ABSTRACT: Hemangioblastoma (HB) is the most common primary intra-axial posterior fossa tumor in adults and is a benign vascular neoplasm. We report the case of a 73-year-old man suffering from biochemical recurrence of prostate cancer where intense overexpression of prostate-specific membrane antigen (PSMA) was observed in HB in a PSMA PET/CT. Overexpression of PSMA in tumor-associated vascular structures has been proposed as an explanation of PSMA ligand uptake in several nonprostatic tumors. Given the pathological nature of HB, this mechanism may explain the intense overexpression of PSMA observed in present case.

Fibrous dysplasia is an uncommon benign bone pathology with only rare potential for malignant transformation. We describe the heterogeneous uptake of fibrous dysplasia of a whole rib on Ga-labeled prostate-specific membrane antigen (PSMA) PET/CT. Ga-PSMA binds to PSMA-expressing prostate cancer cells, but it can also bind to the neovasculature of various solid tumors, as well as to some benign lesions. Ga-PSMA expression in fibrous dysplasia should not automatically be equated with malignant transformation or confused with prostate cancer metastases.

BACKGROUND: Prostate biopsy is a rather frequent procedure, mostly performed in outpatient settings. Bleeding complications following this procedure require precise and delicate management of pre-, peri- and post-procedure anti-coagulation treatments. New oral anti-coagulation drugs (NOACs) are increasingly used. However, the management of such treatments is feared and not yet well known to urologists. A protocol for prostate biopsy management of NOACs seems mandatory. MATERIALS AND METHODS: A review of the literature, using Pubmed and Cochrane databases, together with analysis of several medical associations' recommendations in urology, anaesthesiology, cardiology, oncology and drug safety agency, was performed. RESULTS: There are no recommendations about NOAC management for prostate biopsy available from scientific societies. There is also a lack of specific urological studies. However, several panels of expert recommendations could be helpful in establishing standardized protocols adapted from surgery to prostate biopsy. With the growing use of NOACs, recommendations have shifted to continue anti-coagulant treatment without bridging NOACs for low bleeding risk procedures such as prostate biopsy, in carefully selected groups of patients. CONCLUSION: Extensive indications coupled with the ease of use of NOACs contribute significantly to the widespread replacement of traditional vitamin K antagonist. Knowing that heparin bridging leads to more bleeding, and in the pursuit of more autonomy and safety, urologists should be able to propose dedicated anti-coagulant management using NOACs adapted to carefully selected patients before the prostate biopsy procedure. Further studies and guidelines specific to the concept of non-bridging for anti-coagulant-requiring patients are mandatory for this routine procedure.
RESUMEN
An incidental finding of a testicular mass in young male population is always a case of great concern for the patient and controversy for the physician. Differential diagnosis ranges from acute scrotum (notably testicular torsion), to acute inflammation and infection, all the way to testicular tumors. We present a case of an incidental finding of a painless testicular solid mass in a 19-year-old male patient, with an end pathological result of paradidymis (organ of Giraldes) following orchiectomy. To the best of our knowledge, this is the first case of its kind to be reported in the literature.
RESUMEN
OBJECTIVES: The true incidence of symptomatic deep venous thrombosis (DVT) and pulmonary embolism (PE) in patients undergoing laparoscopic radical prostatectomy is unknown. Our aim was to determine the incidence of symptomatic DVT and PE and the risk factors for these complications. METHODS: Fourteen surgeons from 13 referral institutions from both Europe and the United States provided retrospective data for all 5951 patients treated with laparoscopic radical prostatectomy (LRP), with or without robotic assistance, since the start of their institution's experience. Symptomatic DVT and PE within 90 d of surgery were regarded as venous thromboembolism (VTE). DVT was diagnosed mostly by Doppler ultrasound or contrast venography and PE by lung ventilation/perfusion scan or chest computed tomography or both. Statistical analysis included evaluation of incidence of symptomatic DVT and PE and risk factors as determined by exact methods and logistic regression. RESULTS: Of 5951 patients in the study, 31 developed symptomatic VTE (0.5%; 95% confidence interval [CI], 0.4%, 0.7%). Among patients with an event, 22 (71%) had DVT only, 4 had PE without identified DVT, and 5 had both. Two patients died of PE. Prior DVT (odds ratio [OR]=13.5; 95%CI, 1.4, 61.3), current tobacco smoking (OR=2.8; 95%CI, 1.0, 7.3), larger prostate volume (OR=1.18; 95%CI, 1.09, 1.28), patient re-exploration (OR=20.6; 95%CI, 6.6, 54.0), longer operative time (OR=1.05; 95%CI, 1.02, 1.09), and longer hospital stay (OR=1.05; 95%CI, 1.01, 1.09) were associated with VTE in univariate analysis. Neoadjuvant therapy, body mass index, surgical experience, surgical approach, pathologic stage, perioperative transfusion, and heparin administration were not significant predictors. CONCLUSIONS: The incidence of symptomatic VTE after LRP is low. These data do not support the administration of prophylactic heparin to all patients undergoing LRP, especially those without risk factors for VTE.
