A new bladder-emptying method in females with neurogenic bladder: A randomized, phase II trial.

AIM: To evaluate the performance of the new device compared with clean intermittent catheterization (CIC). METHODS: From March 2015 to March 2018, patients who were admitted to the urologic outpatient clinic. A new intraurethral self-retaining device (ISRD) was made of medical grade silicone and it was inspired by similar catheters that use sliding disks to adjust or fix tubes used to drain the bladder. Patients were randomized into two groups (experimental group [GI]-ISRD vs control group [GII]-CIC). The evaluation was performed at the time of enrollment and 6 months after treatment. Intervention was initiated from the antisepsis of the perineal region and subsequent introduction of the device through the external urethral meatus. The primary outcome was quality of life (QOL). Urinary tract infections (UTIs) episodes, data on urodynamic parameters, adverse effects and number of diapers per day. RESULTS: A total of 177 subjects were analyzed. We found a significant improvement on QOL analysis in the ISRD group (P < .01). ISRD group presented an important reduction (two episodes after ISRD use) on number of UTIs (P < .01) and diaper use, and significant improvement on bladder capacity (80 mL of the average improvement) (P < .01) and compliance (P = .01). Among all registered serious adverse effects, ISRD presented with lower proportion. CONCLUSIONS: The new device has shown to be a safe and promising alternative for adequate emptying of the neurogenic bladder in female patients. Our study has a limitation that is related to a limited period of observation.

A cross sectional single institution study of quality of life in adult patients with spina bifida.

OBJECTIVE: To describe and compare differences in perception of independence, urinary continence, and quality of life in an adult spina bifida (SB) population. METHODS: We collected data on adult neurogenic bladder patients which included demographics, relevant procedures, and quality of life (QoL) questionnaires. QoL and functional outcomes were assessed using spinal cord independence measure (SCIM) and SF-8 health questionnaire. International consultation of incontinence questionnaire (ICIQ) was used to assess incontinence. Comparisons were drawn between patients who underwent surgical reconstruction and those who did not. Student t-tests were used for comparisons and a P-value <0.05 was considered statistically significant. RESULTS: Fifty-four patients with SB were included. A total of 43% underwent bladder augmentation (BA) and 30% underwent antegrade continence enema (ACE). Patients with BA scored 49 ± 25 on the SCIM survey while those without had higher scores of 68 ± 19 with a P-value of 0.016. This difference remained evident when patients with ACE were excluded. When comparing ICIQ and SF-8, no statistically significant differences were found between those who underwent surgical procedures and those who did not. CONCLUSIONS: Assessing QoL in congenital NGB patients is a complex task. In our cohort, patients who underwent BA and ACE were shown to have decreased SCIM scores. SCIM scores for BA patients were significantly higher in patients who did not receive a BA independent of ACE status. SF-8 and ICIQ scores did not show any statistically significant difference in quality of life survey scores in those who underwent procedures versus those who did not.

Quality of life in complete spinal cord injury patients with a Brindley bladder stimulator compared to a matched control group.

AIMS: To determine the effects on Quality of Life (QoL) of a Brindley procedure, which combines a sacral dorsal root rhizotomy to treat neurogenic detrusor overactivity with sacral anterior root stimulation to enable micturition, defecation, and penile erections in complete spinal cord injury (SCI) patients compared to a matched Control Group. METHODS: Cross-sectional study. The Qualiveen questionnaire, SF-36 questionnaire, and multiple choice questions about urinary continence and urinary tract infections were sent to 93 patients who had a Brindley stimulator implanted in the Netherlands and a matched Control Group of 70 complete SCI patients with neurogenic detrusor overactivity. Primary study outcomes were Specific Impact of Urinary Problems score and general QoL index of the Qualiveen. RESULTS: Response rates were 78% and 40% for patients with a Brindley stimulator and controls, respectively. Stimulators were still used for micturition in 46 (63%). These patients had a significant better Specific Impact of Urinary Problems score, general QoL index (Qualiveen), and continence rate, and less urinary tract infections compared to the Control Group. Patients also benefited of the rhizotomy with regard to QoL and continence rate if the stimulator was not used anymore. The subscales of the SF-36 had better scores for the patients who used their stimulator as compared to those who did not use the stimulator and compared to the Control Group. CONCLUSIONS: The Brindley stimulator for complete spinal cord injury patients improves Quality of Life, continence, and urinary tract infection rate compared to a matched Control Group.

Patient preferences for next generation neural prostheses to restore bladder function.

STUDY DESIGN: A survey administered to 66 individuals with spinal cord injury (SCI) implementing a choice-based conjoint (CBC) analysis. Six attributes with three levels each were defined and used to generate choice sets with treatment scenarios. Patients were asked to choose the scenario that they preferred most. OBJECTIVES: To determine the utility weights for treatment characteristics as well as the overall preference for the three types of neural prostheses (NP), that is Brindley, rhizotomy-free Brindley, and pudendal nerve stimulation. Earlier studies have revealed the importance of restoration of bladder function, but no studies have been performed to determine the importance of NP features. SETTING: Two academic affiliated medical systems' SCI outpatient and inpatient rehabilitation programs, Cleveland, OH. METHODS: CBC analysis followed by multinomial logit modeling. Individual part-worth utilities were estimated using hierarchical Bayes. RESULTS: Side effects had the greatest significant impact on subject choices, followed by the effectiveness on continence and voiding. NPs with rhizotomy-free sacral root stimulation were preferred (45% first choice) over pudendal afferent nerve stimulation (39% second choice) and sacral root stimulation with rhizotomy (53% third choice). Almost 20% did not want to have an NP at all times. CONCLUSION: CBC has shown to be a valuable tool to support design choices. The data showed that persons would prefer a bladder NP with minimally invasive electrodes, which would give them complete bladder function, with no side effects and that can be operated by pushing a button and they do not have to recharge themselves.

Transanal irrigation in myelomeningocele children: an alternative, safe and valid approach for neurogenic constipation.

STUDY DESIGN: A total of 60 children with myelomeningocele referred to Spina Bifida Center of Rome (31 boys and 29 girls; aged 8-17 years) were treated with transanal irrigation for three months. OBJECTIVE: To investigate whether transanal irrigation is a valid and alternative approach for neurogenic constipation in children with myelomeningocele. METHODS: A questionnaire on bowel disturbances, quality of life and side effects was completed before the beginning and at the termination of the study. SETTING: Italy. RESULTS: About 60% (36/60) of patients reported relief from constipation and 75% (12/16) for fecal incontinence. Wheelchair-bound and walking patients showed same high improvement of bowel habit. Mean (s.d.) scores before and after the study were: neurogenic bowel dysfunction total score: 17.5 (5.2) versus 8.5 (4.3) (P<0.001); digital stimulation of anorectum: 4.2 (2.8) versus 1.3 (2.5) (P<0.01); frequency of fecal incontinence: 5.5 (1.2) versus 1.3 (1.7) (P<0.01) and degree of general satisfaction: 3.0 (2.4) versus 7.7 (1.5) (P<0.001).We observed a reduction of urinary tract infections during the course of treatment: 14 total urinary tract infections (9 caused by Escherichia coli) before versus 6 (3) during treatment (P<0.01). CONCLUSION: Transanal irrigation in children with myelomeningocele is an alternative and relatively safe approach for managing neurogenic constipation; in fact, it improves bowel disturbances, quality of life and seems to reduce the risk of urinary tract infections.

Conservative treatment of the neuropathic bladder in spinal cord injured patients.

Different conservative treatment modalities for the lower urinary tract dysfunction in patients with spinal cord lesion are reviewed. Conservative treatment is still the mainstay of the urological management in these patients. Growing experience has changed the classical approach. Spontaneous voiding with and without triggered voiding and/or bladder expression has proven to be less safe except in well defined patients with regular urological follow-up. Nowadays, intermittent catheterisation and self catheterisation with and without bladder relaxants are accepted as the methods of choice. Condom catheters are still needed if incontinence persists, while penile clamps have no place in the treatment of patients with spinal cord lesions. Long-term indwelling catheters should be avoided. External electrical stimulation can be used to correct the neurogenic dysfunction by neuromodulation and/or to induce a direct therapeutic response in the lower urinary tract.

Urobehavioral intervention in the rehabilitation of lower urinary tract dysfunction: a case report.

A case study illustrates the usefulness of behavioral analysis and paradoxical strategy in the treatment of life-long urgency incontinence in a cerebral palsy patient. Volitional increase in diurnal enuresis appeared to result in rapid (within 5 days) acquisition of continence. From pretreatment to 13 month follow-up interview, the weekly wetting frequency decreased from an average of 25 to 0.5 episodes. Symptom rehearsal is believed to have interrupted the typical pathobehavioral sequence between the urge to void and micturition.
