Article Synopsis
- The study aimed to evaluate whether examining the vasa deferentia tissues (after a vasectomy) is helpful when many patients don't follow up with post-vasectomy semen analysis (PVSA).
- It analyzed data from 388 patients who underwent vasectomy, comparing PVSA results for different histological categories of the vasa (completely divided vs. incomplete).
- The findings indicate that the histological examination of the vasa can be beneficial in cases of low PVSA compliance, as incomplete divisions don't negatively affect semen analysis results.
Objectives: To determine if multiparametric MRI prostate cancer (PC) lesion dimensions in different axes could distinguish between PC, grade group (GG) >2, and GG >3 on targeted transperineal biopsy and create and validate a predictive model on a separate cohort.
Methods: The maximum transverse, anterio-posterior, and cranio-caudal lesion dimensions were assessed against the presence of any cancer, GG >2, and GG >3 on biopsy by binary logistic regression. The optimum multivariate models were evaluated on a separate cohort.
We presented an extremely rare entity of 'hybrid' oncocytoma and collecting duct (Bellini) carcinoma. The intratumoural coexistence of benign and malignant cells may lead to false diagnosis and suboptimal treatment of an aggressive tumour. Diagnosis may be challenging if only based on imaging modalities.

Patients/subjects And Methods: In all, 3651 patients were identified retrospectively across 12 UK hospitals over a 1-year period. Radiation exposure was defined in terms of total fluoroscopy time (FT) and dose area product (DAP).
