Objective: To determine if preoperative catheter dependence or specimen weight is associated with failed trial without catheter (TWOC) following holmium laser enucleation of the prostate (HoLEP).
Material And Methods: The study population consisted of 143 consecutive men who underwent HoLEP by a single surgeon over 10 months. Ten were excluded from analysis because they did not have a TWOC on the morning following surgery. Preoperative catheter dependence and specimen weight as well as catheter reinsertions were analyzed.
Results: Of 133 men included in analysis, 23 (17.3%) required catheter reinsertion. Of the 23 requiring catheter reinsertion, 6 were catheter dependent preoperatively and 17 were not. Men who were catheter dependent had a lower overall rate of failed TWOC compared to those who were not catheter dependent (15.0% vs 18.3%, P = .647). Mean specimen weight for men requiring catheter reinsertion was significantly lower than men who passed their TWOC (49.9 gm vs 73.1 gm, P = .013).
Conclusion: Very few studies exist on factors associated with short-term catheter reinsertion following HoLEP or other prostatic hyperplasia procedures. We hypothesized that preoperative catheter dependence and small specimen weight would predispose to catheter reinsertion. Specimen weight was inversely related to risk of catheter reinsertion after HoLEP and preoperative catheter dependence was not associated with catheter reinsertion. In men with small prostates, consideration should be given to delayed TWOC to allow resolution of capsular edema and accumulation of clot in the prostatic fossa. Transition zone volume below which delayed TWOC should be considered is the subject of future studies.

Subcutaneous emphysema is a well-known complication of chest tube insertion that can become life-threatening. Severe cases often progress rapidly, necessitating prompt intervention to prevent complications such as airway obstruction and respiratory failure. We report the case of a 57-year-old man who developed extensive subcutaneous emphysema following chest tube insertion.

Neonatal peripheral intravenous catheters (PIVCs) can be difficult to insert, often requiring multiple attempts, with each attempt causing pain and delaying treatment. The aim of this study was describe the clinical characteristics of neonates requiring multiple PIVCs during hospitalization. A secondary case series of neonates requiring three or more PIVCs during their admission were identified from a cohort admitted to an Australian Neonatal Unit between October 2020 and February 2021.

Objective: To develop and validate a nomogram model for predicting central venous catheter-related infections (CRI) in patients with maintenance hemodialysis (MHD).
Methods: MHD patients with central venous catheters (CVCs) visiting the outpatient hemodialysis (HD) center of Xuzhou Medical University Affiliated Hospital from January 2020 to December 2023 were retrospectively selected through a HD monitoring system. Patient data were collected, and the patients were divided into training and validation sets in a 7:3 ratio.

The occurrence of anterior abdominal wall ulcer at the site of the peritoneal catheter (PC) is one of the rarest complications of peritoneal dialysis (PD). When present, it is mainly caused by which respond well to vancomycin therapy. Despite well-conducted therapy, there is a tendency to relapse and induce peritonitis, which makes it necessary to remove the PC and change the dialysis model of treatment and/or re-insert the catheter at another place to preserve PD as a treatment method.

Purpose: This study evaluated the impact of choosing the right versus left internal jugular vein (IJV) for initial central venous catheter (CVC) placement on hemodialysis catheter-related outcomes in critically ill patients.
Materials And Methods: Medical records from the University of Maryland Medical Center were reviewed for adult critical care patients who received an IJV CVC between January 1, 2019, and December 31, 2022, and later required an additional temporary hemodialysis catheter.
Results: The study included 214 patients, with 100 (46.
