Objective: To study the influence of clean intermittent catheterization (CIC) on the lower urinary tract function in patients with urinary retention (UR) due to detrusor underactivity (DU).
Material And Methods: A longitudinal study was carried out on 49 patients (28 men, 21 women) of mean age 55years, who underwent CIC for UR secondary to DU. The mean CIC frequency was 3.15 times/day. Patients' clinical data were collected, and they underwent urodynamic study before and after CIC, with a mean interval of 4years. Fisher's exact test was used for the analysis of categorical variables and Student's t test for parametric variables. The level of significance was set at 0.05 for a two-tailed test.
Results: The second urodynamic study showed a significantly increased bladder compliance, the Bladder Outlet Obstruction Index (BOOI) and the Bladder Contractility Index (BCI) also increased but without reaching statistical significance. There was a significantly higher percentage of benign prostatic hyperplasia (BPH) and acontractile detrusor cases among the group of patients whose BCI improved after CIC, with significantly lower CIC time.
Conclusions: CIC improved bladder compliance in the patients of our series. The BCI improved in BPH patients and in patients with acontractile detrusor.

Introduction: Clean intermittent catheterization (CIC) has significant advantages over indwelling catheters. To facilitate CIC, a continent catheterizable channel (CCC) to the bladder is required in some cases. The Mitrofanoff appendicovesicostomy (APV) is considered the gold standard for pediatric CCC creation.

Purpose: The purpose of this study was to explore the experiences of intermittent catheter users after using both reusable and single-use catheters, with a particular focus on factors that affected acceptability.
Design: Qualitative descriptive study following a clinical trial.
Participants And Setting: Thirty-six participants who had used both reusable and single-use catheters in a clinical trial were interviewed between June 2022 and March 2024.
Improving the Stability of Gas Diffusion Electrodes for CO Electroreduction to Formate with Sn and In-Based Catalysts at 500 mA cm: Effect of Electrode Design and Operation Mode.

The electrochemical carbon dioxide reduction reaction (CORR) using renewable electricity sources could provide a sustainable solution for generating valuable chemicals, such as formate salt or formic acid. However, an efficient, stable, and scalable electrode generating formate at industrially viable current densities (>100 mA cm) is yet to be developed. Sn or In-based catalysts in gas diffusion electrodes (GDE) can efficiently produce formate.

Purpose: Study aimed to compare incidence of urinary tract infection (UTI), type of bacteria grown, development of antibiotic resistance over 2 years in children whose caregivers underwent training based on the Roy Adaptation Model with an android phone application for patients clean intermittent catheterization (RAMACIC) versus those whose caregivers received routine training in hospital.
Method: This study was conducted as a descriptive, prospective study with 40 patients and caregivers between October 2021 and 2023 as a continuation of a previously conducted randomized controlled experimental study by the researchers. Data were collected the "Participant Form," and "Urine Test Form" analyzed with the SPSS 22 package.

A serious limitation to the deployment of IoT solutions in rural areas may be the lack of available telecommunications infrastructure enabling the continuous collection of measurement data. A nomadic computing system, using a UAV carrying an on-board gateway, can handle this; it leads, however, to a number of technical challenges. One is the intermittent collection of data from ground sensors governed by weather conditions for the UAV measurement missions.
