RESUMEN
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.

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.

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 χ(2)-test. CONCLUSIONS: IVES represents a possible therapeutic option for incomplete SCI patients with N-NOR.

AIM: The aim of the study was to evaluate the efficacy of sacral nerve modulation for chronic pelvic pain after pelvic or anal surgery for benign disease. METHOD: From January 2004 to December 2009, 17 (14 female; age 56 years) consecutive patients suffering from chronic pelvic pain underwent evaluation for sacral nerve modulation in three pelvic floor units. RESULTS: The previous surgery included stapled transanal rectal resection (five), hysterectomy (four), haemorrhoidectomy (two), stapled haemorrhoidopexy (one), fistulectomy (one), urethral sphincterotomy (one), appendicectomy (one), discectomy (one) and laparoscopy for endometriosis (one). Eight (47%) patients fulfilled the criteria for definitive implantation and were followed for a mean of 39 months. Using a visual analog pain score, pain levels fell from 8.2 preoperatively to 1.9, 2.1, 2.0 and 1.8 at 6, 12, 24 and 36 months, respectively. Age < 60 years and duration of symptoms of < 24 months were good predictors and stapling was a poor predictor of success. CONCLUSION: Sacral nerve modulation seems to be effective over time in some patients with chronic pain related to previous surgery.

OBJECTIVES: To assess the concomitant clinical improvement in incomplete spinal cord injury patients (SCIPs) suffering from neurogenic bowel symptoms (NBSs), neurogenic lower urinary tract symptoms (NLUTSs) and neurogenic erectile dysfunction (NED) using sacral neuromodulation (SNM) for NBSs and NLUTSs. METHODS: Seventy-five SCIPs were selected. Before and during the follow-ups post-SNM, NLUTSs and NBSs were detected mainly through specific diaries. Erectile function was assessed using the International Index of Erectile Function composed of 5 questions (IIEF5). Quality of life (QoL) was measured with the Short Form 36 Health Survey questionnaire (SF-36). During the first stage, in which a permanent electrode was inserted percutaneously into the third sacral foramina and stimulated using an external generator, patients with NBSs or NLUTSs were required to improve their symptoms by at least 50% compared with baseline before proceeding to the second stage in which the generator was placed in the patient's buttock. NED patients needed to increase their IIEF5 score by at least 25% compared with baseline (evaluated initially 3 months after the second stage) in order to continue follow-up. RESULTS: Fourteen out of 37 subjects who manifested two functional pelvic dysfunctions at baseline maintained notable clinical improvement in two pelvic functions (median follow-up >3 years). Six had non-obstructive retention (NOR) and NED, six double incontinence, and two constipation with NOR. In the general and mental health domains of the SF-36, all patients improved their scores by at least 20% compared with baseline. CONCLUSIONS: SNM may be beneficial to selected incomplete SCIP with concomitant pelvic functional disturbances.

STUDY DESIGN: Retrospective study. OBJECTIVES: Efficacy and safety of sacral neuromodulation (SNM) in incomplete spinal cord-injured patients (SCIPs) affected by chronic neurogenic bowel symptoms (NBSs). SETTING: Neurourology Department. Primary to tertiary care. METHODS: Retrospective non-blinded study without controls. Thirty-nine SCIPs were submitted to temporary stimulation for NBS. Permanent implantation was carried out if both their NBSs improved and the Wexner questionnaire scores were reduced by at least 50% during the first stage compared with that at baseline. Outcome measures included episodes of fecal incontinence and number of evacuations per week, as well as the Wexner score and the Short Form 36 (SF-36) Health Survey questionnaire. RESULTS: Twenty-three SCIPs were submitted to definitive SNM, maintaining their clinical benefits after permanent implantation with a median follow-up of 38 months. The length of time since neurological diagnosis to SNM therapy represents the only factor related to the success of the implantation, P<0.05. In subjects with constipation (12), the median number of evacuations shifted from 1.65 to 4.98 per week, whereas the Wexner score changed from 19.91 to 6.82 in the final checkup with P<0.05. In subjects with fecal incontinence (11), the median number of episodes per week in the final follow-up was 1.32 compared with 4.55 pre-SNM. The general and mental health of both groups was measured with the SF-36 questionnaire and consistently showed statistical improvement (P<0.05).Anorectal manometry showed no important variation compared with baseline. There were no major complications. CONCLUSIONS: SNM therapy should be considered for the treatment of NBS for select patients with incomplete spinal cord injury when conservative treatments fail.

OBJECTIVE: To determine the efficacy and safety of sacral neuromodulation (SNM) in incomplete spinal cord injured (SCI) subjects affected by neurogenic lower urinary tract symptoms (NLUTS). METHODS: Twenty-four SCI patients were enrolled. The individuals were divided into two groups: 13 individuals in the urinary retention category and 11 suffering from overactive bladder syndrome. All subjects underwent definitive SNM implantation (Medtronic, Inc.). Voiding symptoms were assessed using patient bladder diaries, which recorded both pre-SNM and before each follow-up (1, 3 and 6 months, and then every 6 months). Outcome measures were per 24 h: number of voids and voided volume per void for both groups; number of urinary leakages, pad use and nocturia for patients with overactive bladder syndrome; and volume per catheterization and number of catheterizations for urinary retention subjects only. Final checkups were completed by June 2008. RESULTS: Median follow-up was 61 months. Up to the final visit, all subjects maintained a clinical improvement of more than 50% compared with baseline. Twenty-two side effects were recorded. Four subjects with urinary retention needed a new implant in the controlateral S3 sacral root because of loss of efficacy. One patient with urinary retention developed a wound infection at the implanted pulse generator site. CONCLUSIONS: Our study contains the largest series of implanted SCI patients ever published. SNM is a therapy to consider in the treatment of NLUTS for partial SCI patients, even if the loss of clinical benefits for patients with retentive NLUTS must be taken into account. All adverse events were treated effectively.

STUDY DESIGN: Thirty-six patients with unsatisfactory treatment of neurogenic bowel dysfunctions (NBD) were enrolled from Spinal Units and Rehabilitation Centers in Italy. Treatment was for 3 weeks using a newly developed integrated system with an enema continence catheter for transanal irrigation (Peristeen, Coloplast A/S Kokkedal Denmark). OBJECTIVES: To evaluate the effects of Peristeen Anal Irrigation on NBD and patient quality of life (QoL). SETTING: Italy. METHODS: Lesion level, ambulatory status and hand functionality were determined in all patients. NBD symptoms and QoL were evaluated before and after treatment, using a specific questionnaire. Statistical analysis was performed using McNemar Test and Sign Test. RESULTS: Thirty-six patients were enrolled, and 32 patients completed the study. At the end of the treatment, 28.6% of patients reduced or eliminated their use of pharmaceuticals. Twenty-four patients became less dependent on their caregiver. There was a significant increase in patients' opinion of their intestinal functionality (P=0.001), QoL score (P=0.001) and their answers regarding their degree of satisfaction (P=0.001). A successful outcome was recorded for 68% of patients with fecal incontinence, and for 63% of patients with constipation. CONCLUSION: Peristeen Anal Irrigation is a simple therapeutic method for managing NBD and improving QoL. It should be considered as the treatment of choice for NBD, playing a role in the neurogenic bowel analogous to that of intermittent clean catheterization in bladder treatment.

Pharmacological treatment of voiding disorders due to benign prostatic hypertrophy offers a wide variety of pharmacological options. Phytotherapy represents one of the oldest drug used in the treatment of BPH. In the last decade, many studies have been performed to demonstrate efficacy and tolerability of this drug. We report a short literature review on mechanism of action and objective and subjective results of treatments with plant extracts. We report on a comparation between literature data and data of our trials. Safety, tolerability and subjective results seems to indicate that plant extract are still a good pharmacological option in the treatment of BPH micturitional disorders.
