Estimating acute urinary retention risk post prostate high dose-rate (HDR) brachytherapy: A clinical-based recursive partitioning analysis.

CONCLUSION: The overall rate of acute urinary complications post HDR brachytherapy is low, but the individual risk of urinary retention can increase depending on the number of risk factors present. A more patient-directed retention risk estimation can be performed by using the classification risk tree presented here. PMID: 32966843 [PubMed - as supplied by publisher]

Abstract BACKGROUND: Manual volumetric modulated arc therapy (VMAT) treatment planning for high-risk prostate cancer receiving whole pelvic radiotherapy (WPRT) with four integrated dose levels is complex and time consuming. We have investigated if the radiotherapy planning process and plan quality can be improved using a well-tuned model developed through a commercial system for knowledge-based planning (KBP). MATERIAL AND METHODS: Treatment plans from 69 patients treated for high-risk prostate cancer with manually planned VMAT were used to develop an initial KBP model (RapidPlan, RP). Prescribed doses were 5...

CONCLUSIONS: RHESOU is a new tool opened to the different urologic corporations (urologists, pathologists, oncologists, radiotherapists, radiologists) that permits an overview in urological cancers in Herault. Finally, one important aim is that this tool will be adapted when new treatments or new important parameters appear in the years ahead. LEVEL OF EVIDENCE: 3.

(Wolters Kluwer Health) Robotic surgery plays a major role in modern management of prostate cancer, bladder cancer, and other conditions treated by urologists. But it also poses some special challenges as hospitals resume elective surgery amid the COVID-19 pandemic. Problems and solutions facing urologic robotic surgery in the era of COVID-19 are reviewed inUrology Practice ®, an Official Journal of the American Urological Association (AUA). The journal is published in the Lippincott portfolio by Wolters Kluwer.

Hematuria of prostatic origin has multiple etiologies including benign prostatic hyperplasia (BPH), iatrogenic urological trauma, prostate cancer, and radiation therapy. Hematuria secondary to benign prostatic hyperplasia (BPH) can occur because of the increased vascularity of the primary gland, itself, or because of the vascular re-growth following a transurethral resection of the prostate. Prostatic hematuria usually resolves with conservative measures; however, refractory hematuria of prostatic origin (RHPO) may require hospitalization with treatment with blood transfusions, repeated indwelling urinary catheterization, ...

AbstractDosimetric evaluation and variation assessment were performed with two knowledge-based planning (KBP) models created at different periods for volumetric-modulated arc therapy (VMAT) for prostate cancer at five institutes. The first and second models (F- and S-models) for KBP were created before April 2017 and April 2019, respectively. The S-model was created using feedback plans from the F-model. Dose evaluation was compared between the two models using the same two computed tomography (CT) datasets and structures. The evaluation metrics were the dose received by 95.0% and 2.0% of the planning target volume (PTV); ...

Authors: Lin Y, Zhong H, Sun B, Peng Y, Lu F, Chen M, Zhu M, Huang J Abstract Renal cell carcinoma (RCC) is one of the commonest urological tumors. The incidence of RCC ranks third among urological tumors, after prostate cancer and bladder tumors. However, the etiology of RCC remains unclear. Ubiquitin-specific protease 22 (USP22), a potential marker of cancer stem cells, is associated with the occurrence and progression of numerous tumors. However, the roles of USP22 in RCC have not yet been investigated. Survivin is a member of the inhibitor of apoptotic protein family involved in RCC progression. The present stu...

Authors: Murphy N, Shah P, Shih A, Khalili H, Liew A, Zhu X, Lee A Abstract Single-cell sequencing (SCS) is a powerful new tool that applies Next Generation Sequencing at the cellular level. SCS has revolutionized our understanding of tumor heterogeneity and the tumor microenvironment, immune infiltration, cancer stem cells (CSCs), circulating tumor cells (CTCs), and clonal evolution. The following chapter highlights the current literature on SCS in genitourinary (GU) malignancies and discusses future applications of SCS technology. The renal cell carcinoma (RCC) section highlights the use of SCS in characterizing ...
