Sexual rehabilitation in women with spinal cord injury: a critical review of the literature

Study design:Review article.Objectives:Critical review of literature on the multiple aspects of sexual rehabilitation in women with spinal cord injury (SCI) from initial recovery to long-term follow-up.Setting:Neuro-urology Department.Methods:Studies on sexuality selected from PubMed from 1993 to 2009.Results:Literature supported by significant statistical analyses reports that females with complete tetraglegia deserved special attention immediately at initial recovery; sexual intercourse is much more difficult for them (as compared with other women with SCI) mainly because of autonomic dysreflexia and urinary incontinence. There are sparse data on predictable factors favoring sexual rehabilitation such as the age SCI was incurred, the importance of ones sexual orientation, and the SCI etiology. Information after initial discharge is based chiefly on questionnaires, which report that as more time passes since the injury, patients attain more sexual satisfaction compared with recently injured women. Studies on neurological changes after SCI, and their effect on sexual response, are supported by a significant statistical analysis, but with few SCI patients. One topic reported the effect of sildenafil on sexuality, without benefit. No paper offers any detailed analysis on the sexual impact of medical and psychological treatments related to SCI. Literature reports that some co-morbidities are more prevalent in women with SCI compared with able-bodied women but data on sexual functioning are missing.Conclusion:To improve sexual rehabilitation services, sexual issues and response require evaluation during periodical check-ups using validated questionnaires administered by a physician ‘guide’ who coordinates professional operators thus providing personalized programmable interventions.

Treating erectile dysfunction and central neurological diseases with oral phosphodiesterase type 5 inhibitors. Review of the literature.

INTRODUCTION Erectile dysfunction (ED) is reported in a high percentage of patients with central neurological disorders (CND). AIM   An up-to-date review on oral phosphodiesterase 5 inhibitors (PDE5): sildenafil, tadalafil, and vardenafil for individuals with CND and ED. MAIN OUTCOME MEASURES Various questionnaires on ED, such as the International Index of Erectile Function composed of 15 questions. METHODS Internationally published clinical studies evaluating the efficacy and safety of PDE5 on subjects with CND and ED were selected. RESULTS Overall, 28 articles on PDE5 used to treat patients with CND and ED were included. With each of the three PDE5 compared to placebo or erectile baseline, literature reported significant statistical improvement (P < 0.01; P < 0.05) only in patients with spinal cord injury (SCI). PDE5 efficacy was documented for SCI patients up to 10 years. The most frequent predicable factor for PDE5 success was the presence of upper motoneuron lesion. Each of the three clinical sildenafil studies documented statistically significant improvement on erectile function in Parkinsons patients (P < 0.01; P < 0.05). Two studies reported discordant results about sildenafils effectiveness on multiple sclerosis (MS) patients; one on tadalafil showed significant statistical efficacy on erection versus baseline (P < 0.01; P < 0.05). The only spina bifida article determined that sildenafil remarkably improved erectile function. Overall, drawbacks were mostly slight-moderate, except in subjects with multiple system atrophy where sildenafil caused severe hypotension. CONCLUSIONS PDE5 represent first line ED therapy only for SCI patients, though treatment results through meta-analysis were not possible. Encouraging results are reported for Parkinsons and MS patients. PDE5 use for other CND patients is limited for various reasons, such as ED and concomitant libido impairment caused by depression and/or sexual endocrinology dysfunctions, and because PDE5 may cause a worsening of neurological illness. Medical centers staffed by health professionals able to counsel patients on the possible use of PDE5 are needed.

Sacral neuromodulation for neurogenic non-obstructive urinary retention in incomplete spinal cord patients: a ten-year follow-up single-centre experience

Objective:To determine the success rate of percutaneous first stage of sacral neuromodulation (SNM) and the efficacy and safety of permanent SNM for incomplete spinal cord lesion (SCL) patients suffering from chronic neurogenic non-obstructive urinary retention (N-NOR).Method:From January 2003 to December 2012, 85 individuals underwent the percutaneous first stage of SNM. Subsequently, only responders who reached a concomitant reduction by at least 50% of volume per catheterization and in the number of catheterizations per day comparing their 7-day voiding diaries at baseline underwent permanent SNM. Final follow-up was conducted by April 2013.Results:Thirty-six individuals responded to percutaneous first stage of SNM. Post-surgery urodynamics documented all patients experiencing first sensation of bladder filling. A statistically significant increase in Qmax ml per sec and decrease in post-voiding residual urine per ml were documented. (P<0.01). First sensation of bladder filling at baseline represented a statistically significant parameter for the success of the first stage SNM (P<0.05). Eleven out of 34 patients at follow-ups were ‘inconstant responders’ because they returned to similar baseline voiding symptoms, but responded again with an implant on the controlateral S3 sacral root. Two failed twice and responded once again after an S4 sacral root implant. All but one failure occurred more than 3 years after the previous implant. Other drawbacks were resolved telemetrically.Conclusions:Research is needed to increase the success rate of the first stage SNM on incomplete SCL patients with N-NOR. Permanent SNM is highly efficacious in the medium follow-up.

Intravesical electrostimulation versus sacral neuromodulation for incomplete spinal cord patients suffering from neurogenic non-obstructive urinary retention

Objectives:To compare the efficacy of intravesical electrostimulation (IVES) versus sacral neuromodulation (SNM) in patients with incomplete spinal cord lesions (SCL) and neurogenic non-obstructive urinary retention (N-NOR).Methods:In this retrospective study, 77 N-NOR patients underwent IVES (minimum 28 sessions), then after returning to voiding baseline symptoms, percutaneous first stage of SNM (lasting for minimum 4 weeks). After the two neuromodulation treatments, responders were categorized as patients experiencing both a 50% reduction of volume per catheterization per ml and a 50% reduction in number of catheterizations per day when comparing the 7-day voiding diaries at the end of both procedures to baselines. New urodynamics were performed subsequently. Responders to first stage of SNM underwent permanent SNM.Results:Forty-eight patients responded to neither of the treatments, whereas 29 responded to both IVES and first-stage SNM. No significant statistical differences (P>0.05) were detected in the voiding diaries. Following the two procedures, the first sensation of bladder filling was either maintained or recovered by all responders, whereas the same 11 patients reached a bladder contractility index of >100. The 29 IVES responders lost their clinical benefits in a mean follow-up of 9.6 months. Only 10 out of the 29 patients became nonresponsive to permanent SNM, in a mean follow-up of 54 months.Conclusion:A strict correlation in terms of clinical and urodynamic patterns was demonstrated in patients with incomplete SCL and N-NOR, following IVES and first stage of SNM. However, voiding improvement through IVES was short-term when compared with the effects of permanent SNM.

Clinical efficacy of intravesical electrostimulation on incomplete spinal cord patients suffering from chronic neurogenic non-obstructive retention: a 15-year single centre retrospective study.

Objective:To evaluate the clinical and urodynamic impact of intravesical electrostimulation (IVES) on incomplete spinal cord injury (SCI) patients suffering from chronic neurogenic non-obstructive urinary retention (N-NOR).Methods:One-hundred and two patients underwent at least 28 consecutive daily IVES sessions because objective evidence of detrusor acontractility instead of hypocontractility was detected. Diary entries written at various stages by each patient were compared (7 days before the IVES cycle, 15–21 days into the cycle and 7 days before its end). Responders were patients with a mean 50% reduction in both the number of daily catheterizations and post-void residual urine. Responders underwent further urodynamics at the end of the IVES cycle; patients experiencing first sensation of bladder filling, and the mean volume of first sensation of bladder filling per ml, Qmax ml s−1, among others, were evaluated. Nineteen individuals who repeated another IVES round were included in this study.Results:Thirty-eight subjects (37.2%) responded to IVES and of those, 83.3% recovered the first sensation of bladder filling after the IVES round. Nineteen responders repeated IVES within 1 year, owing to loss of efficacy. They obtained similar voiding symptoms improvement and urodynamic results as after the first IVES cycle. A timespan of <2 years from SCI to IVES, and the presence of first sensation of bladder filling at baseline represented significant predictive parameters for IVES success (P<0.05) using χ2-test.Conclusions:IVES represents a possible therapeutic option for incomplete SCI patients with N-NOR.

A retrospective study on female urological surgeries over the 10 years following spinal cord lesion

Objectives:To evaluate the efficacy and safety over a 10-year period of any urological operations required by female patients with spinal cord lesions (SCLs).Methods:Retrospective study of urological surgeries from our database performed on females with SCLs from 2001 to 2002. Surgery efficacy for neurogenic lower urinary tract dysfunctions (N-LUTDs) was evaluated by comparing 7-day voiding diaries pre- and post-surgeries, while individual investigations were done pre- and post-surgery to evaluate urological complications. Drawbacks were assessed.Results:Thirty-eight out of 69 patients underwent one or more urological procedures. Twenty-one out of 42 patients with suprasacral lesions underwent interventions for N-LUTD. The main surgical treatment was endoscopic detrusor infiltration of botulinum-A (Botox 300 UI or Dysport 750 UI) performed 107 times on 15 subjects using aseptic intermittent catheterizations for neurogenic overactive bladder. Mean efficacy duration was 9.2 months. Six females with infrasacral lesions underwent at least one intervention for N-LUTD. Two females in each group underwent tension-free vaginal tape for stress urinary incontinence (SUI), reducing episodes per week of SUI by >90% after 5 years. The most serious urological complication was active vesico-ureteral reflux (VUR) in three patients, treated endoscopically with submucosal injection of Macroplastique. No VUR recurrence was detected during a 6-year follow-up. All bladder stones (five cases) and renal calculi (five cases) were treated with endoscopic transurethrally electrohydraulic lithotripsy and extracorporeal shock-wave lithotripsy, respectively. Overall, no serious drawbacks were observed.Conclusions:Mini-invasive surgeries were exclusively used to address urological issues in chronic SCL patients.
