The effect of non-surgical weight loss interventions on urinary incontinence in overweight women: a systematic review and meta-analysis.

Although the aetiology of urinary incontinence can be multifactorial, in some cases weight loss could be considered as a part of the therapeutic approach for urinary incontinence in people who are overweight. The objective of this study was to review and meta-analyse the effect of non-surgical weight loss interventions on urinary incontinence in overweight women. Web of Science, PubMed, Pedro, SPORTDiscus and Cochrane were systematically searched for clinical trials that met the a priori set criteria. Data of women who participated in non-surgical weight loss interventions (diet, exercise, medication or a combination) were included in the meta-analysis. After removing duplicates, 62 articles remained for screening on title, abstract and full text. Six articles (totalling 2,352 subjects in the intervention groups) were included for meta-analysis. The mean change in urinary incontinence (reported as frequency or quantity, depending on the study) after a non-surgical weight loss intervention, expressed as standardized effect size and corrected for small sample sizes (Hedges' g), was -0.30 (95%CI = -0.47 to -0.12). This systematic review and meta-analysis shows evidence that a non-surgical weight loss intervention has the potential to improve urinary incontinence and should be considered part of standard practice in the management of urinary incontinence in overweight women.

Value of increase in bladder capacity in treatment of refractory monosymptomatic nocturnal enuresis in children.

OBJECTIVES: To evaluate children with refractory monosymptomatic nocturnal enuresis to determine whether detrusor overactivity (DOA) plays a role in 4 weeks of unsuccessful treatment with retention control training (RCT); whether an increase in bladder capacity can eventually be obtained by RCT plus oxybutynin; and whether the increase in capacity is the primary key to success. METHODS: Sixty-eight children with refractory monosymptomatic nocturnal enuresis were included. They all had a maximal cystometric capacity less than the age-expected value. RCT was done by water loading and retention to the point of urgency once daily. During training, changes in bladder capacity were evaluated by voiding charts. If after 4 weeks of RCT, less than a 10% increase in bladder capacity was noted, oral oxybutynin was added. RESULTS: The incidence of DOA was 66%. After 4 weeks of RCT, the bladder capacity increased in 20.6%. Combining RCT with oxybutynin led in the end to normalization of the bladder capacity in 79.4%. Older age and high-pressure DOA negatively influenced the ability to increase the bladder capacity. Fifteen children became completely dry, mainly by converting enuresis to nocturia. CONCLUSIONS: Unsuccessful RCT is often caused by DOA, especially if a bladder capacity rise of at least 10% cannot be achieved within 4 weeks. If oxybutynin is added to the treatment, normalization of bladder capacity can be obtained in most. This increased bladder capacity cures enuresis only in a minority by sharpening their arousal and provoking nocturia.

The role of bladder biofeedback in the treatment of children with refractory nocturnal enuresis associated with idiopathic detrusor instability and small bladder capacity.

PURPOSE: Not all children with primary nocturnal enuresis, an unstable detrusor and small bladder capacity can be treated successfully with anticholinergics and bladder drill. We report our use of bladder biofeedback in patients who did not respond to 3 months of such treatment. MATERIALS AND METHODS: A total of 24 patients (median age 10.4 years) were studied. For bladder biofeedback a transurethral catheter was placed and connected with a 3-way connector. The bladder was slowly filled through this catheter and the intravesical pressure could be seen on a vertical tube, which was also connected to the transurethral catheter. The perineal bulbar detrusor inhibiting reflex was used in cases of involuntary bladder contraction. During the day patients retained urine as long as possible and completed a micturition chart. RESULTS: Of the 24 patients bed-wetting stopped completely in 17 and decreased in 6, and treatment failed in 1. All patients were followed for at least 6 months after treatment. There were 2 cases of recurrence in the group that was cured. CONCLUSIONS: Intravesical biofeedback can successfully treat patients with refractory primary enuresis associated with unstable detrusor and small bladder capacity.

Bladder biofeedback for the treatment of refractory sensory urgency in adults.

OBJECTIVE: Evaluation of bladder biofeedback in patients with sensory urgency refractory to medication and classical bladder training. METHODS: In 12 such patients a non-electronic technique of bladder biofeedback was used. Ambulatory treatment sessions were done once a week for 4 weeks, as opposed to every 14 days, with a mean total treatment period of 8 weeks. Micturition charts were completed before, during and 14 days after treatment by the patient. Before starting, patients had a mean of 15.8 micturitions/day, 2.3 micturitions/night, and a mean functional bladder capacity of 96 ml (26-172 ml). Urodynamic investigation showed a low-capacity bladder, hypersensitivity in some patients, and normal urodynamic parameters in others. RESULTS: At the end of biofeedback, patients had a mean of 5.7 micturitions/day, 0.3 micturitions/night, and a mean functional bladder capacity of 296 ml (163-470 ml). The results 9 months after completing the treatment were unchanged. Quality of life improved substantially in all. CONCLUSIONS: Bladder biofeedback is a valuable treatment for sensory urgency refractory to classical treatment.
