Article Synopsis
  • Hospitals often split standard platelet units into low-dose units to address shortages, but their effectiveness in actively bleeding patients was previously untested.
  • A study compared outcomes of patients in cardiac surgery receiving low-dose platelets versus whole-dose platelets over 18 months and found no significant differences in transfusion needs, bleeding complications, or mortality rates.
  • The findings suggest low-dose platelets may be as effective as whole-dose options during shortages, but further multicenter research is recommended to validate these results.*

Postoperative stress urinary incontinence (SUI) after Holmium Laser Enucleation of the Prostate (HoLEP) has improved with the early apical release (EAR) technique. However, some patients develop SUI despite using EAR HoLEP. The aim of this study is to investigate whether a novel classification of the external sphincter is correlated with postoperative SUI.

Introduction: Comprehensive sexuality education (CSE) is associated with positive sexual and reproductive health (SRH) outcomes, including increased contraceptive use, lower rates of unintended pregnancy and prevention of sexual violence. However, implementation of and requirements for CSE vary across the United States which can negatively impact students, both during and beyond high school, including among college students.

Methods: and Analysis: This paper describes the research protocol for a multi-staged approach for designing, implementing and evaluating an SRH course for up to 60 undergraduate students at a public university in California.

Purpose: The Manufacturer and User Facility Device Experience database contains anonymous, voluntary medical device reports. A review of device-related adverse events associated with Benign Prostatic Hyperplasia surgeries was completed. The objective was to evaluate the occurrence and contributing factors to clinically significant complications in a cohort of patients electing to undergo surgical intervention for Benign Prostatic Hyperplasia.

Objective: To investigate the difference in postoperative incontinence and quality of life comparing standard vs early apical release (EAR) Holmium Laser Enucleation of the Prostate (HoLEP).

Methods: A retrospective review was performed to identify patients who underwent HoLEP from December 2021 to December 2022 at a single tertiary referral center with two participating consultant urologists. Patients were assessed with questionnaires and evaluated clinically.

Objective: To evaluate and compare the financial burden of various surgical interventions for the management of benign prostatic hyperplasia (BPH).

Methods: We identified commercially insured men with a diagnosis of BPH who underwent a procedure of interest (simple prostatectomy (SP), transurethral resection of the prostate (TURP), holmium laser enucleation of the prostate (HoLEP), photovaporization of the prostate (PVP), prostatic urethral lift (PUL), or water vapor thermal therapy (WVTT)) between 2015 and 2021 with the OptumLabs Data Warehouse. Primary outcome was total health care costs (THC) which included both patient out-of-pocket (OOP) and health plan paid costs for the index procedure and combined follow-up years 1-5.

To assess the performance characteristics of a lab-developed multiplex PCR assay for the detection of common bacterial pathogens associated with infections in pediatric patients from normally sterile sites, such as cerebrospinal fluid, synovial and pleural fluids. A total of 272 specimens were tested by PCR and traditional culture methods to assess the presence of , , , methicillin-sensitive and methicillin-resistant and . Compared with culture, the overall positive and negative percentage agreement of the PCR were 95.

Objective: To determine if same day catheter removal is feasible in a population of holmium laser enucleation of the prostate patients who received paralysis and if bladder pressure monitoring could predict successful catheter removal.

Methods: From February 2021 to February 2022, we evaluated same day catheter removal for patients undergoing holmium laser enucleation of the prostate. Criteria for proceeding with same day catheter removal included: an uncomplicated procedure, continuous bladder irrigation weaned within 120 minutes of arrival to PACU, minimal postoperative hematuria and a bladder pressure over 30 cmH0 as measured using the VP Test device (SRS Medical).

Objective: To compare the cost-effectiveness of surgical interventions for BPH.

Methods: Using a Markov model, a cost-utility analysis was performed comparing HoLEP, B-TURP, WVTT, and PUL for prostate size <80cc (index patient 1) and HoLEP and SP for prostate size >80cc (index patient 2). Model probabilities and utility values were drawn from the literature.

Introduction: Benign prostatic hyperplasia (BPH) is a common condition affecting aging men. While holmium laser enucleation of the prostate (HoLEP) is one of the most effective treatments for BPH, variations of the procedure, such as median lobe HoLEP (MLHoLEP), are rarely reported. Here, we report our institution's experience with partial HoLEP.

Purpose: To study the safety, efficacy and trends in index procedures leading to salvage holmium laser enucleation of the prostate (S-HoLEP).

Methods: This was a single-institution retrospective review of HoLEPs performed between 2006 and 2020. Patients who underwent S-HoLEP were compared to those undergoing primary holmium laser enucleation of the prostate (P-HoLEP).

Purpose/objectives: Holmium laser enucleation of the prostate (HoLEP) is commonly performed in patients with significant bladder outlet obstruction. However, there are few reports on the toxicity of external beam irradiation (RT) for prostate cancer in patients after prior HoLEP. In this study, we evaluate the side effects and treatment outcomes of RT after HoLEP.

Introduction: Holmium laser enucleation of the prostate (HoLEP) is an effective but underutilized option for the surgical management of benign prostatic hyperplasia (BPH). With low adoption, questions arise surrounding patients access to care. It is unclear whether patients undergoing HoLEP are local or specifically seek care from afar.

Objective: To describe a new technique for single incision robotic cystectomy and Studer-type ileal neobladder using the single-port (SP) da Vinci SP robotic platform.

Methods: In April 2021, a 71 year-old patient underwent a single incision robotic cystectomy and orthotopic Studer-type ileal neobladder using the single-port da Vinci SP robotic platform for cT2, cN0 urothelial carcinoma of the bladder. He was not a candidate for neoadjuvant cisplatin-based combination chemotherapy and declined participation in a clinical trial.

Unlabelled: INTRODUCTION Bladder stones have historically been associated with urinary stasis secondary to bladder outlet obstruction (BOO). Recent studies indicate that the role of BOO in bladder stone formation is minor. We evaluate the role of urinary lithogenic factors in bladder stone formation by comparing the compositions of bladder stones and kidney stones in patients with multi-site urinary calculi.

Although the incidence of anterior cruciate ligament injuries continues to rise, return to sport (RTS) rates remain low and risk of the second injury remains high. No gold-standard criteria exist for medical clearance to RTS after anterior cruciate ligament reconstruction. The lack of consensus may be driven by the multifactorial nature of the clinical decision that includes a combination of physical and psychological factors.
