Overactive bladder: The importance of new guidance.

Overactive bladder (OAB) affects an estimated 49 million people in Europe, but only a minority receive appropriate treatment. Others are bothered by unacceptable levels of symptoms that severely impair their quality of life and represent a significant financial burden to themselves and to their healthcare providers. Recently updated guidelines from the International Consultation on Incontinence (ICI) and the European Association of Urology (EAU) take account of important new developments in the management of bladder problems in both primary and secondary care. However, local implementation of previous guidance has been variable, with many patients with OAB and other bladder problems failing to gain full benefit from current clinical and scientific understanding of these conditions. The recent expansion of the range of treatments available for OAB and stress urinary incontinence makes it especially important that physicians become aware of the differential diagnosis of these conditions - the questions they need to ask, and the investigations which will help determine the most appropriate course of action.

The role of neuromodulation in the management of urinary urge incontinence.

OBJECTIVE: To examine the benefit-risk profile of neuromodulation in treating refractory urinary urge incontinence and other voiding disorders. PATIENTS AND METHODS: The outcome measures from all patients in pivotal clinical trials who had undergone sacral nerve stimulation were analysed retrospectively. RESULTS: Neuromodulation was effective in several clinical studies; the response is durable and the benefit-risk profile good. CONCLUSION: Sacral nerve stimulation is becoming the standard of care for refractory overactive bladder and retention problems. The potential benefit of neuromodulation should be included in female urology and gynaecology training programmes.

Safety and efficacy of alfuzosin 10 mg once-daily in the treatment of lower urinary tract symptoms and clinical benign prostatic hyperplasia: a pooled analysis of three double-blind, placebo-controlled studies.

OBJECTIVES: To examine the efficacy and safety of a once-daily formulation of alfuzosin in a pooled analysis of three parallel, randomized, double-blind, placebo-controlled 3-month studies of patients with lower urinary tract symptoms (LUTS) consistent with clinical benign prostatic hyperplasia. PATIENTS AND METHODS: Patients were randomized to receive alfuzosin, 10 mg once-daily (473) or placebo (482) for 12 weeks. Primary efficacy criteria were improvements in the International Prostate Symptom Score (IPSS) and peak urinary flow rate (PFR). RESULTS: Alfuzosin significantly improved the mean (sd) IPSS, by - 6.0 (5.1) vs - 4.2 (5.7) with placebo (P < 0.005) and the PFR, by + 2.3 (3.8) vs + 1.1 (3.1) ml/s with placebo (P < 0.001), irrespective of prostate size. The significant improvement in LUTS included the irritative and the obstructive subscore of the IPSS and the nocturia criterion; the PFR increased rapidly and significantly, from the first visit (14 days). The quality-of-life score also improved significantly in alfuzosin-treated patients. Alfuzosin was well tolerated; the number of withdrawals for adverse events was comparable in both treatment groups. The most frequently reported adverse event was dizziness (placebo 2.9%, alfuzosin 6.1%). There were no significant changes in blood pressure with alfuzosin compared with placebo, including in elderly and hypertensive patients. Sexual adverse events were rare (abnormal ejaculation, 0.6%). CONCLUSIONS: The once-daily formulation of alfuzosin, administered at 10 mg with no dose titration is effective, with a good safety profile, especially in elderly and hypertensive patients.

Efficacy of desmopressin in the treatment of nocturia: a double-blind placebo-controlled study in men.

OBJECTIVE: To investigate the efficacy and safety of oral desmopressin in the treatment of nocturia in men. PATIENTS AND METHODS: Men aged >/=18 years with verified nocturia (>or=two voids/night) and nocturnal urine production greater than their maximum functional bladder capacity were recruited. A 3-week dose-titration phase established the optimum desmopressin dose (0.1, 0.2 or 0.4 mg). After a 1-week 'washout' period, patients who responded in the dose-titration period were randomized to receive the optimal dose of desmopressin or placebo in a double-blind design for 3 weeks. RESULTS: In all, 151 patients entered the double-blind period (86 treated with desmopressin, 65 with placebo). In the desmopressin group 28 (34%) patients and in the placebo group two (3%) patients (P<0.001) had fewer than half the number of nocturnal voids relative to baseline; the mean number of nocturnal voids decreased from 3.0 to 1.7 and from 3.2 to 2.7, respectively, reflecting a mean decrease of 43% and 12% (P<0.001). The mean duration of the first sleep period increased by 59% (from 2.7 to 4.5 h) in the desmopressin group, compared with an increase of 21% (from 2.5 to 2.9 h) in the placebo group (P<0.001). The mean nocturnal diuresis decreased by 36% (from 1.5 to 0.9 mL/min) in the desmopressin group and by 6% (from 1.7 to 1.5 mL/min) in the placebo group (P<0.001). The mean ratio of night/24-h urine volume decreased by 23% and 1% (P<0.001), and the mean ratio of night/day urine volume decreased by 27% and increased by 3% (P<0.001) for the desmopressin and placebo groups, respectively. In the double-blind treatment period, similar numbers of patients had adverse events; 15 (17%) patients in the desmopressin and 16 (25%) patients in the placebo group. Most adverse events were mild. Serum sodium levels were <130 mmol/L in 10 (4%) patients and this occurred during dose-titration. CONCLUSIONS: Orally administered desmopressin is an effective and well-tolerated treatment for nocturia in men.

Tolterodine once-daily: superior efficacy and tolerability in the treatment of the overactive bladder.

OBJECTIVES: To evaluate the efficacy and tolerability of a new extended-release (ER), once-daily, capsule formulation of tolterodine, relative to placebo and the existing immediate-release (IR), twice-daily, tablet formulation, for treatment of the overactive bladder. METHODS: This was a double-blind, multicenter, randomized, placebo-controlled trial. One thousand five hundred twenty-nine patients (81% women) with urinary frequency (eight or more micturitions every 24 hours) and urge incontinence (five or more episodes per week) were randomized to oral therapy with tolterodine ER 4 mg once daily (n = 507), tolterodine IR 2 mg twice daily (n = 514), or placebo (n = 508) for 12 weeks. Efficacy was assessed at the end of the treatment period on the basis of the micturition diary variables. Tolerability and safety were assessed by evaluating the adverse events, electrocardiogram parameters, laboratory values, and treatment withdrawals. RESULTS: Tolterodine ER 4 mg once daily (P = 0.0001) and tolterodine IR 2 mg twice daily (P = 0.0005) both significantly reduced the mean number of urge incontinence episodes per week compared with placebo. The median reduction in these episodes as a percentage of the baseline values was 71% for tolterodine ER, 60% for tolterodine IR, and 33% for placebo. The ER formulation was 18% more effective than the IR formulation (P <0.05). Treatment with both formulations of tolterodine was also associated with statistically significant improvements in all other micturition diary variables compared with placebo. For both formulations, the mean decreases in micturition frequency (P <0.0079) and pad usage (P <0.0145) were significant, and the mean volume voided per micturition increased (P = 0.0001). The rate of dry mouth (of any severity) was 23% for tolterodine ER, 30% for tolterodine IR, and 8% for placebo. The overall dry mouth rate for patients taking tolterodine ER was 23% lower than for tolterodine IR (P <0.02), and the rate of severe dry mouth in the ER group was only 1.8%. The rates of withdrawal were comparable for the two active groups and the placebo group. No safety concerns were noted. CONCLUSIONS: Tolterodine ER 4 mg once daily is effective and well tolerated in the treatment of overactive bladder with no safety concerns. Tolterodine ER demonstrated an improved efficacy for reducing urge incontinence episodes and a lower frequency of dry mouth compared with the existing IR twice-daily formulation.

The effects of 4 weeks treatment with cisapride on cystometric parameters in spinal cord injury patients. A double-blind, placebo controlled study.

A group of 21 complete spinal cord injury patients, beyond the phase of spinal shock, were given a treatment of cisapride at random, 10 mg four times a day for 4 weeks. Cystometry was performed first before the start and during the following 4 weeks. No statistically significant difference could be found in the urodynamic parameters between the two groups at the first cystometry. No statistically significant change of the urodynamic parameters could be demonstrated with the treatment, although a non-statistically significant bladder stimulating effect was present in a majority of the patients in the cisapride group.

Inverted papilloma of bladder: clinical significance.

Based on 15 cases of inverted urothelial papilloma, we present the clinical significance of these lesions in view of the current literature. An inverted papilloma should raise suspicion with respect to the whole urothelial surface. However, approaching every lesion of this type as a (pre-)neoplastic tumor does not seem justified, since 90 percent of all cases reported so far do not present any clinical or histologic feature of malignancy. Some factors, such as the patient's history, eventually associated urothelial carcinomas, or histologic features of malignant transformation within an inverted papilloma, must be taken into consideration. If no single indication in favor of malignancy has been disclosed, we believe follow-up with yearly endoscopic investigations, in addition to regular urine cytologies, may suffice.
