“…The overall success rate of TWOC seen in a large worldwide survey published by British Journal of Urology was around 61% after a median of five days of catheterization [12], which is very similar to our study, while another study conducted in India showed that increasing number of days of catheterization does not make any significant difference to chances of success after TWOC [13], which is in contrast to our study where a significant difference of 16.6% was seen with seven days of catheterization and re-catheterization was significantly reduced. Significant controversy exists in the literature regarding days of catheterization, i.e.…”

Background: The most common cause of acute urinary retention in men over 50 is benign prostate enlargement (BPE). Following the urethral catheterization, a trial without a catheter (TWOC) under the cover of alpha-blockers is given. The timing of TWOC varies from Day 3 to Day 7 of the retention episode. There is a need to study the improvement in the success rate of TWOC with the increasing number of days of catheterization.Objective: To measure the success rate of TWOC in acute urinary retention due to benign prostatic enlargement with increasing days of catheterization.Method: The study was conducted in Social Security Teaching Hospital Lahore. Patients who presented with acute urinary retention due to benign prostatic enlargement were catheterized and given alpha-blockers. The patients were divided into two groups, one group having TWOC after three days and the other having TWOC after seven days. The success rate of TWOC was calculated and compared in the two groups. All patients included in the study had the first episode of acute retention with a moderately enlarged prostate and no element of second pathology or neurological deficit.Results: A total of 48 patients were included in the study, divided into two groups of 24 patients each. In the first group who underwent TWOC after seven days of catheterization, 15 out of 24 patients had successful TWOC with a success rate of 62.5%. In the second group of 24 patients, who had TWOC after three days of catheterization, only 11 patients had successful TWOC with a success rate of 45.8%.Conclusion: There was a marked improvement in the success rate of TWOC with increasing days of catheterization after an acute retention episode, secondary to BPE.

“…La infección del conducto urinario aparece cuando las bacterias evitan las defensas normales del huésped y obtienen acceso a la vejiga, incluso evitan, al mismo tiempo, el contacto con los péptidos con acción bactericida, las citocinas y las moléculas de adhesión del urotelio. 8 La curvatura del tubo de la bolsa recolectora de orina aumenta el riesgo de bacteriuria, quizá por el aumento de la contrapresión hidrostática que resulta del vaciado incompleto de la vejiga. 9 Los sistemas cerrados de drenaje urinario representan uno de los elementos más importantes de profilaxis contra las infecciones de las vías urinarias.…”

ANTECEDENTES: La disfunción de la bolsa recolectora de orina afecta todo el sistema de drenaje urinario y provoca consecuencias importantes para los pacientes. OBJETIVO: Analizar las complicaciones originadas por el uso de la bolsa recolectora de orina tradicional disponible y compararlas con las de la bolsa modificada de Chavolla. MATERIALES Y MÉTODOS: Estudio prospectivo, transversal, no aleatorizado, efectuado en pacientes con diagnóstico de hematuria persistente que requirieron sonda transuretral con cistoclisis y bolsas recolectoras de orina. Los pacientes se dividieron en grupo 1: bolsa tradicional y grupo 2: bolsa modificada de Chavolla. Para el análisis estadístico se utilizaron medias y desviación estándar de las variables cuantitativas y proporciones (frecuencias) de las variables cualitativas. Los resultados de las medias y desviación estándar se compararon con t de Student y las frecuencias con c2. RESULTADOS: Se registraron 35 pacientes: 10 en el grupo 1 y 25 en el grupo 2. Ambos tuvieron edad y comorbilidades similares. En todos los pacientes del grupo 1 falló el sistema de drenaje y requirieron el cambio por la bolsa modificada de Chavolla (tiempo promedio de 3 horas). En el grupo 2 no se registraron fallas de la bolsa colectora de orina. La principal complicación en todos los casos fue la obstrucción de la bolsa por un coágulo, sin atribuirse per se a la intensidad del sangrado. CONCLUSIÓN: La bolsa recolectora de orina modificada de Chavolla es efectiva en pacientes con cistoclisis por hematuria.

“…Meanwhile, the control position available just during the insertion of the device prevents the involuntary leakage of urine thanks to a specific in‐built membrane. In this way, it is possible to regulate the flow of urine and reduce the risk of CAUTI 9 . T‐Control® has an additional safety lock to prevent inadvertent or accidental catheter openings.…”

The aim of this study was to analyse the experience of users of indwelling bladder catheters and evaluate the anticipated usability of a prototype of the T‐Control® urinary catheter (without being inserted) by patients who were able to compare the differences between the T‐Control® prototype and other urinary catheters and urinary catheter accessories. A qualitative study was conducted with people who had lived with an indwelling urinary catheter for at least 1 week. Two user‐centred design techniques were applied: patient experience trajectory map and Think Aloud, a method where the participants were able to express their previous experiences, expectations and preferences while manipulating the devices. The experiential trajectory was collected based on a semi‐structured following interviews. Participants were able to manipulate the new T‐Control® and, based on their previous experiences, compare the potential usability of T‐control® with Foley‐type catheter and its accessories All the participants stated that they had experienced negative emotions concerning bladder catheterisation during the trajectory of use, from the initial prescription and adaptation to the follow‐up, and the forced life changes that a permanent catheterisation implies. The most frequent emotions were rejection and sadness. The new T‐Control® device could potentially improve the patient experience, as all participants perceived advantages related to the closure system, ease of use, safety and discretion. Participants also noted its closure system as an advantage and highlighted its ease of use, although one‐handed operation required some learning. Catheters currently on the market are functional, but some patients do not always have a satisfactory experience. This might negatively affect their quality of life, so there is a wide market opportunity for new devices that improve clinical and psychological care. Based on patient evaluation, the new T‐Control® device with a built‐in valve could provide benefits for patients.
