“…Ricci et al [6] found single-channel cystometry to be a useful adjunct to clinical examination in women with UI. Single-channel cystometry interpreted carefully in relation to clinical findings is considered a reasonably accurate, safe and cheap method for diagnosing neurogenic bladder dysfunction, especially in spinal cord injuries [7]. In another study comparing single-and multi-channel cystometry as a screening tool for detrusor instability in women, single-channel studies had acceptable specificity but the predictive value was poor as a screening tool [8].…”

Objective: To determine if the interpretation of urodynamic studies (UDS) in children without a rectal catheter may be similar to multi-channel studies, as UDS in children are challenging and can sometimes be difficult to interpret. Patients and methods: In this retrospective pilot study, 115 paediatric pressure-flow studies were included. A blinded investigator was given two sets of UDS traces. The first set had the vesical trace of all children and the second set had the multi-channel trace. The agreement between the interpretations of both the sets was tested by Cohen's κ, and sensitivity, specificity, and predictive values were expressed with 95% confidence intervals (CIs). The voiding pattern was compared and Pearson's correlation coefficient was used to analyse the pressure at maximum urinary flow (Q max). Results: The most common indications for UDS were neurogenic bladder and posterior urethral valves. The interpretation of compliance and detrusor overactivity by single-channel analysis had a positive predictive value of 92.1% (95% CI 84.7-96.1%) and 89.4% (95% CI 78.3-95.6%), respectively, and a negative predictive value of 100% and 97.1% (95% CI 89.5-99.2%) respectively, in comparison to multi-channel analysis. Children with underactive detrusor were identified reliably by analysing the straining pressure pattern and flow curve. Amongst children who voided, the pressure at Q max showed a moderate correlation (Pearson's coefficient = 0.53) between the two groups. Conclusion: Rectal catheters may be avoided in a carefully selected group of children undergoing UDS who only need filling phase assessment.

“…1 In addition, studies have applied ultrasound to enhance the management of pressure ulcers, bladder dysfunction, and musculoskeletal and vascular conditions in patients with SCI. [3][4][5] Ongoing research and development efforts are leveraging ultrasound's versatility to target multiple systems to improve both functional outcome and quality of life of patients with SCI. This trend supports our belief that ultrasound technology is well-poised to become a powerful multifaceted adjunct in the management of acute and chronic SCIs.In the context of neurorehabilitation after SCI, we agree with Abdulla et al that a robust closed-loop system based on physiologically and functionally sound and meaningful feedback signals is paramount to success.…”
