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.

Urinary tract dysfunction in multiple sclerosis: is there a relation with disease-related parameters?

et al. 1997

The lower urinary tract is a ected by multiple sclerosis in many patients. We screened urologically and neurologically 120 patients with a con®rmed diagnosis of multiple sclerosis. The mean age was 42 years (range 22 to 69 years). Urodynamic investigation as well as neuro-urophysiological investigations were performed in all patients. Renal ultrasound was used to study morphology, and excretory urogram (IVU) was used to assess renal function and the upper urinary tracts in 105 patients. Obstructive symptoms were found more commonly than irritative symptoms. The urinary symptoms were found to be related to disease duration and not to disability status. Urodynamic abnormalities were statistically signi®cantly related to disease duration (X 2 =38.51; P=0.0001), and to the disability status (X 2 =76.70; P=0.0001). Few patients, only 3.3%, had upper urinary tract dilatation. With medical management, hydronephrosis disappeared in all of the patients and did not recur. A combination of oral pharmacological agents and clean intermittent catheterization was used in the majority of the patients.We conclude that lower urodynamic abnormalities can be present in every patient with multiple sclerosis, and appear to be related to disease duration and disability status, thus early treatment based upon urodynamic evaluation and close follow-up can reduce morbidity and improve the quality of life.

Objectives.To investigate what combination of easily available parameters allows the noninvasive prediction of infravesical obstruction in optimal agreement with urodynamic classification. Urodynamically, men with lower urinary tract symptoms suggestive of benign prostatic hyperplasia are classified as nonobstructed or obstructed. Methods. Mandatory and recommended tests were performed in 160 consecutive men with lower urinary tract symptoms suggestive of benign prostatic hyperplasia. The classification of the International Continence Society, the group-specific urethral resistance factor, and Schä fer's obstruction grade were estimated from urodynamic studies. The frequency-volume charts were analyzed. A separate group of 173 consecutive men was used for validation. Results. The formula, prostate volume (in cubic centimeters) Ϫ 3 ϫ maximal urinary free flow rate (in milliliters per second) Ϫ 0.2 ϫ mean voided volume (in milliliters; as estimated from frequency-volume charts), was optimal in the classification compared with the urodynamic classification. Extension of this formula to more than three parameters did not result in better selection. As estimated from receiver operating characteristic curves, the accuracy of the formula appeared to be good. The method of quantifying urethral resistance minimally affected the classification that resulted from the combination. From the results, a diagram was created presenting the probability of an individual to have infravesical obstruction. The validation results were satisfactory. Conclusions. The prediction of the probability of a man with lower urinary tract symptoms suggestive of benign prostatic hyperplasia to have infravesical obstruction can be deduced from a diagram based on a formula composed of three readily available parameters: prostate volume, maximal urinary free flow rate, and mean voided volume. UROLOGY 63: 476-480, 2004. © 2004 I n the past, methods were developed to diagnose bladder outlet obstruction (BOO) noninvasively in men with lower urinary tract symptoms (LUTS) suggestive of benign prostatic hyperplasia (BPH). The clinical prostate score (CLIPS), introduced by Rosier et al., 1 was composed of scores for prostate volume, maximal urinary flow rate, postvoid residual urinary volume, and voided volume and had a superior correlation with urodynamically objective BOO than did isolated parameters. The BOO number (BOON) introduced by van Venrooij and Boon, 2 was calculated from the prostate volume, maximal urinary free flow rate, and relative postvoid residual urine volume, defined as the postvoid residual urine volume divided by the bladder volume at a strong desire to void (times 100%). Schacterle et al. 3 combined the maximal urinary flow rate and American Urological Association symptom index, 4 and Steele et al. 5 combined the symptom score, maximal free flow rate, and prostate volume for predicting BOO. Ockrim et al. 6 developed a BOO index based on the maximal free flow rate and prostate volume. Kuo 7 established a clinical prostate sc...
