A Novel Risk Prediction Model to Triage Difficult Urethral Catheterizations.

Urology 2021 Jun 18. Epub 2021 Jun 18.

Columbia University Irving Medical Center Department of Urology, New York, NY. Electronic address:

Objective: To construct a risk prediction model to identify cases of difficult urethral catheterizations (DUC) in order to prevent complications from improper placement.

Materials And Methods: Using a single-institution database of urologic consults for Foley catheterizations from June 2016 to January 2020, a model to predict DUC in male patients was constructed.

Outcomes and Cost Evaluation Related to a Single-Use, Disposable Ureteric Stent Removal System: a Systematic Review of the Literature.

Curr Urol Rep 2021 Jun 15;22(8):41. Epub 2021 Jun 15.

Urology Department, University Hospital Southampton NHS Trust, Tremona Road, Southampton, SO16 6YD, UK.

Purpose Of Review: To present the latest evidence related to the outcomes and cost of single-use, disposable ureteric stent removal system (Isiris).

Recent Findings: Our review suggests that compared to a reusable flexible cystoscope (re-FC), a disposable flexible cystoscope (d-FC) with built-in grasper (Isiris) significantly reduced procedural time and provided a cost benefit when the latter was used in a ward or outpatient clinic-based setting. The use of d-FC also allowed endoscopy slots to be used for other urgent diagnostic procedures. Read More

Is it time to offer True Minimally Invasive Treatments (TMIST) for BPH? - A review of office-based therapies and introduction of a new technology category.

Can J Urol 2021 04;28(2):10580-10583

Division of Urology, University Health Network, University of Toronto, Toronto, Ontario, Canada.

INTRODUCTION The options for treating benign prostatic hyperplasia (BPH) beyond medication and traditional transurethral surgery continue to expand. Undesirable side effects to medication and surgeries have driven interest toward minimally invasive surgical therapies (MISTs), including convective water vapor ablation (Rezum) and prostatic urethral lift (UroLift). While these treatments can be performed outside of the operating room, they do require special equipment and the use of rigid cystoscopy. Read More

Monotypic Plasma Cell Proliferation of Uncertain Clinical Significance Mimicking Interstitial Cystitis: An Early Lesion of MALT Lymphoma?

Am J Surg Pathol 2021 Jun;45(6):841-853

Department of Anatomical Pathology, Douglass Hanly Moir Pathology, Macquarie Park.

We prospectively studied our institutional experience of bladder extranodal marginal zone (mucosa-associated lymphoid tissue [MALT]) lymphoma including bladder biopsies in which the possibility of MALT lymphoma was considered. We identified a subset of cases primary to the urinary bladder, presenting with prominent plasma cell infiltrates and symptoms mimicking bladder pain syndrome/interstitial cystitis. These proliferations were designated for this study as "monotypic plasma cell proliferation of uncertain clinical significance" (MPCP-US), as the features were insufficient for diagnosis of MALT lymphoma.

Phenotypic Analysis of Urothelial Exfoliated Cells in Bladder Cancer via Microfluidic Immunoassays: Sialyl-Tn as a Novel Biomarker in Liquid Biopsies.

Front Oncol 2020 16;10:1774. Epub 2020 Sep 16.

International Iberian Nanotechnology Laboratory, Department of Life Sciences, Braga, Portugal.

Bladder cancer is the most common malignancy of the urinary tract, having one of the highest recurrence rates and progression from non-muscle to muscle invasive bladder cancer that commonly leads to metastasis. Cystoscopy and urine cytology are the standard procedures for its detection but have limited clinical sensitivity and specificity. Herein, a microfluidic device, the UriChip, was developed for the enrichment of urothelial exfoliated cells from fresh and frozen urine, based on deformability and size, and the cancer-associated glycan Sialyl-Tn explored as a putative bladder cancer urinary biomarker.
