ABSTRACT
Objectives: This study compared the infection rates, degree of encrustation, symptoms, and complications in patients regarding the duration of urethral catheterisation (three weeks, six weeks, and eight weeks). Design: A cross-sectional study with stratified simple random sampling Setting: Urology Unit, Korle Bu Teaching Hospital Participants: One hundred and thirty-seven male patients with long-term urinary catheters Interventions: Participants were grouped into 3 weeks, 6 weeks, and 8 weeks duration of catheter replacementsPrimary outcomes measures: Symptoms due to the urinary catheters, urinalysis, urine and catheter tip cultures, sensitivity, and catheter encrustations were assessed. Results: Eighty-six patients had a primary diagnosis of benign prostatic hyperplasia (BPH), 35 had urethral strictures,13 had prostate cancer, two had BPH and urethral strictures, and one participant had bladder cancer. There was no difference in the symptoms the participants in the different groups experienced due to the urinary catheters (p > 0.05). The frequency of occurrence of complications (pyuria, p = 0.784; blocked catheter, p=0.097; urethral bleeding, p=0.148; epididymo-orchitis, p=0.769 and bladder spasms, p=1.000) showed no differences in the three groups. There was no statistical difference in the urinalysis for the three groups (p>0.05) and the degree of encrustations (3 weeks: 0.03 ± 0.06, 6 weeks: 0.11±0.27 and eight weeks: 0.12 ±0.27) with p=0.065. Conclusions: In this study, the duration of urinary catheterisation using silicone Foley's catheters did not influence the complication and symptom rates; hence silicon catheters can be placed in situ for up to 8 weeks before replacement instead of the traditional three-weekly change.

Intravascular catheters are widely used in Neonatal Intensive Care Units. The major types of intravascular access in the newborn are peripheral catheters, venous or arterial umbilical catheters, central venous catheters and peripherally-inserted central venous catheters (PICC). Anomalous positioning of catheters, especially umbilical catheters, is quite frequent as their installation is without imaging guidance. The radiographic assessment of the catheter performed by pediatricians and/or radiologists, who must be able to recognize those poorly positioned as they can cause serious complications, is essential. This article contains a sample of correct and misplaced catheter x-ray often used in a NICU.
Los catéteres intravasculares son ampliamente utilizados en las Unidades de Cuidado Intensivo Neonatal. Dentro de los métodos de acceso intravascular en el RN se incluyen catéteres periféricos, catéteres umbilicales arteriales o venosos, catéteres venosos centrales y catéteres venosos centrales de instalación periférica (CCIP). Las posiciones anómalas de los catéteres, especialmente de los catéteres umbilicales son frecuentes ya que su instalación no es guiada por imágenes. Dado lo anterior es muy importante la evaluación radiológica de control de los catéteres que realizan los médicos pediatras y/o radiólogos, quienes deben ser capaces de reconocer aquellos mal posicionados ya que pueden causar complicaciones graves. Este artículo contiene una muestra pictográfica de radiografías de catéteres de uso frecuente en UCI Neonatal, bien y mal posicionados.
