Objective To assess different aspects of sexual function in men with spinal cord injury (SCI) using the Male Sexual Quotient (MSQ), a newly developed tool to assess sexual function and satisfaction. Design Cross-sectional study. Setting Tertiary rehabilitation center. Participants Patients (N=295) older than 18 years (mean age ± SD, 40.7±14.5y) with SCI for more than 1 year (median time since SCI, 3.6y; range, 1.6–7.0y) were assessed from February to August 2012. Patients completed the MSQ questionnaire and the Sexual Health Inventory for Men (SHIM). Interventions Not applicable. Main Outcome Measures Performance in various domains of sexual function was evaluated using the MSQ and SHIM questionnaires. Results Erectile function, ejaculation, and orgasm were the most severely affected domains. The median MSQ score was 40 (range, 8–66), and the median SHIM score was 5 (range, 0–16). The diagnostic properties of the 2 instruments were similar in the discrimination of sexually active subjects. The area under the receiver operating characteristic curve was .950 (95% confidence interval [CI], .923–.979) for the MSQ and .942 (95% CI, .915–.968) for the SHIM. There was a strong correlation between the 2 instruments ( r =.826; 95% CI, .802–.878). Conclusions Different domains of sexual function are severely impaired in men with SCI, although their sexual interest remains high. The MSQ and SHIM scores strongly correlate, but the MSQ provides a more comprehensive assessment of sexual dysfunction in male patients with SCI.

Background: Epidemiological features of spinal cord injury (SCI) have been changing over the last decades. We evaluated the contemporary trends in the epidemiology of traumatic SCI patients from a rehabilitation center. Methods: In a cross-sectional study, a consecutive series of 348 patients with traumatic SCI were evaluated. Variables were collected through an epidemiological form, which included gender, age at injury, duration and cause of SCI. We investigated SCI epidemiological trends over time including the association between gender and age at injury with SCI features such as etiology, injury severity and level. Results: The mean age at SCI has increased from 26.0 ± 11.8 in patients with SCI before 2003 to 37.9 ± 15.7 in those with SCI after 2009 (p < 0.001). Gunshot wounds were the main cause of injury in patients with SCI before 2003, dropping from 40.6 to 16.9% after 2009 and being surpassed by road traffic injuries (38.6%) and falls (31.4%) after 2009 (p < 0.001). Gender, SCI severity and level have not changed significantly over the time. Conclusions: There was a major increase in the average age of patients as well as changes in the etiology of SCI over the past fifteen years, including a significant decrease in gunshot wounds and an increase in the frequency of road traffic injuries and falls. These changes and accompanying risk factors must be taken into consideration when planning measures to prevent SCI.

To evaluate whether the ice water test (IWT) should be performed before or after the standard urodynamic investigation (UDI).Two cohorts of patients suffering from neurogenic lower urinary tract dysfunction (NLUTD) due to spinal cord injury (SCI) were matched by lesion level and age. The patients of cohort A (n=55, retrospective cohort) underwent the IWT before and the patients of cohort B (n=110, prospective cohort) after standard UDI. The IWT effect on urodynamic parameters has been compared between the two groups using the Mann-Whitney U-test for independent samples. UDI was performed according to good urodynamic practices recommended by the International Continence Society.The mean age of both cohorts was 49 years. Performing the IWT before versus after standard UDI resulted in a significantly lower maximum cystometric bladder capacity (P=0.01), lower incidence of detrusor overactivity (P=0.017) and lower maximum detrusor pressure during IWT (P=0.04). All other urodynamic parameters assessed demonstrated no significant difference (P0.05).Our results are in line with findings from animal studies demonstrating a bladder cooling-induced gating effect on the micturition reflex volume threshold on the level of sacral interneurons. Since the IWT is an unphysiological investigation that might significantly bias subsequent urodynamics, we suggest that the IWT should not precede more physiological standard UDI.

We investigated whether same session repeat urodynamic investigations are needed in patients with neurogenic lower urinary tract dysfunction.A consecutive series of 226 patients with neurogenic lower urinary tract dysfunction who underwent same session repeat urodynamic investigation was prospectively investigated at a single university spinal cord injury center. Urodynamics were done according to the good urodynamic practices recommended by the International Continence Society. All 226 patients underwent same session repeat consecutive filling cystometry and 88 also underwent pressure flow studies if they could void spontaneously. Repeatability of the 2 measurements was assessed using the Bland and Altman 95% limits of agreement, and the κ statistic.Mean age of the 226 patients enrolled was 52 years (range 18 to 90). Of the patients 94 (42%) were women and 132 were (58%) men. Detrusor overactivity repeatability was excellent between the 2 urodynamic investigations (κ=0.87, 95% CI 0.80-0.94). For all other urodynamic parameters assessed there were wide 95% limits of agreement for differences in the parameters, indicating poor repeatability.In same session repeat urodynamic investigations of patients with neurogenic lower urinary tract dysfunction detrusor overactivity demonstrates excellent repeatability but all other urodynamic parameters show insufficient agreement. Thus, we strongly recommend that clinical decision making not be based on a single urodynamic investigation since repeat measurements may yield completely different results.

Background Combined pelvic floor electromyography (EMG) and videocystourethrography (VCUG) during urodynamic investigation are the most acceptable and widely agreed methods for diagnosing detrusor external sphincter dyssynergia (DESD). Theoretically, external urethral sphincter pressure (EUSP) measurement would provide enough information for the diagnosis of DESD and could simplify the urodynamic investigation replacing combined pelvic floor EMG and VCUG. Thus, we evaluated the diagnostic accuracy of EUSP measurement for DESD. Patients & Methods A consecutive series of 72 patients (36 women, 36 men) with neurogenic lower urinary tract dysfunction able to void spontaneously was prospectively evaluated at a single university spinal cord injury center. Diagnosis of DESD using EUSP measurement (index test) versus combined pelvic floor EMG and VCUG (reference standard) was assessed according to the recommendations of the Standards for Reporting of Diagnostic Accuracy Initiative. Results Using EUSP measurement (index test) and combined pelvic floor EMG and VCUR (reference standard), DESD was diagnosed in 10 (14%) and in 41 (57%) patients, respectively. More than half of the patients presented discordant diagnosis between the index test and the reference standard. Among 41 patients with DESD diagnosed by combined pelvic floor EMG and VCUR, EUSP measurement identified only 6 patients. EUSP measurement had a sensitivity of 15% (95% CI 5%–25%), specificity of 87% (95% CI 76%–98%), positive predictive value of 60% (95% CI 30%–90%), and negative predictive value of 56% (95% CI 44%–68%) for the diagnosis of DESD. Conclusions For diagnosis of DESD, EUSP measurement is inaccurate and cannot replace combined pelvic floor EMG and VCUR.

We compared the urodynamic parameters of ambulatory vs nonambulatory acute spinal cord injured patients.A total of 27 women and 33 men (mean age 58 years) with neurogenic lower urinary tract dysfunction due to acute spinal cord injury (duration of injury less than 40 days) were prospectively evaluated. The patients were dichotomized according to the mobility for moderate distances subscale of the SCIM (Spinal Cord Independence Measure) version III into ambulatory (score of 3 or greater) and nonambulatory (score less than 3). Videourodynamic parameters including maximum detrusor pressure during the storage phase, bladder compliance, detrusor overactivity, detrusor external sphincter dyssynergia and vesicoureterorenal reflux were compared between the groups.Of the 60 patients with acute spinal cord injury 17 were ambulatory and 43 were nonambulatory. Mean ± SD duration of injury at urodynamic investigation was 30 ± 8 days. The lesion level was cervical in 14 patients, thoracic in 28 and lumbar/sacral in 18. Comparing unfavorable urodynamic parameters, no significant differences were found between ambulatory vs nonambulatory patients in terms of a high pressure system during the storage phase (29% vs 33%, p = 0.81), a low compliance bladder (12% vs 7%, p = 0.54), detrusor overactivity (24% vs 47%, p = 0.1), detrusor external sphincter dyssynergia (18% vs 21%, p = 0.77) and vesicoureterorenal reflux (0% vs 5%, p = 0.36).Ambulatory and nonambulatory patients with acute spinal cord injury have a similar risk of unfavorable urodynamic measures. Thus, we strongly recommend the same neurourological assessment including urodynamic investigations in all acute spinal cord injury patients independent of the ability to walk.
