OBJECTIVE

To present a prospective long‐term evaluation of the bone‐anchored male sling (InVanceTM, American Medical Systems, Minnetonka, MN, USA) for patients with moderate to severe stress urinary incontinence (SUI) after prostate surgery

PATIENTS AND METHODS

Forty‐five patients had a male sling implanted for SUI after prostate surgery. The evaluation before and after surgery included a complete history and physical examination, various questionnaires (American Urological Association Symptom Score, University of California Los Angeles/RAND prostate index), cysto‐urethroscopy, International Continence Society (ICS) 1‐h pad test and a urodynamic study. The follow‐up assessments were at 2, 6 and 12 months after surgery, and yearly thereafter. The success rate was defined as the percentage of patients ‘dry’ and ‘improved’.

RESULTS

The median (range) follow‐up was 36 (2–64) months. Twelve patients (27%) had previous adjuvant radiotherapy. Eighteen patients (40%) had moderate SUI (two or three pads/day) and 27 (60%) had severe SUI (more than three pads/day). All preoperative ICS 1‐h pad tests were positive. The success rate was 76%; 16 patients were dry (36%), 18 were improved (one or two pads/day, 40%) and in 11 the sling was a failure (24%); 76% of ICS 1‐h pad tests were negative after surgery. The postoperative urodynamic study showed no signs of bladder outlet obstruction. In all, 72% of patients were satisfied/very satisfied with the surgery and 86% considered themselves cured/almost cured. The success rate was not affected by the presence of previous radiotherapy or the severity of SUI. Ten patients had perineal numbness, but in all it resolved within 1–3 months. There was one mesh infection which required its removal. There was no urethral erosion.

CONCLUSION

Compared to previous studies, the InVance male sling had a good success rate for moderate and severe SUI, with a median follow‐up of 36 months. The results did not differ for moderate or severe SUI or with the presence of previous radiotherapy.  相似文献

The artificial urinary sphincter remains the gold standard for treatment of post‐prostatectomy urinary incontinence. The AMS 800 (American Medical Systems, Minnetonka, MN, USA) is the most commonly implanted artificial urinary sphincter. Having been on the market for almost 40 years, there is an abundance of literature regarding its use, but no recent review has been published. We reviewed the current literature regarding the indications, surgical principles, outcomes and complications of artificial urinary sphincter implantation for stress urinary incontinence after prostatectomy. A PubMed search was carried out for articles on the artificial urinary sphincter from 1995 to present. The review was centered on articles related to the use of the AMS 800 for stress urinary incontinence in males after prostatectomy. Relevant articles were reviewed. The majority of patients will achieve social continence (1 pad per day) after artificial urinary sphincter implantation; however, rates of total continence (no pad usage) are significantly lower. Patient satisfaction outcomes average greater than 80% in most series. Potential complications requiring reoperation include infection (0.5–10.6%) and urethral erosion (2.9–12%). Revision surgeries are most commonly as a result of urethral atrophy, which ranges from 1.6 to 11.4%. The 5‐year Kaplan–Meier freedom from reoperation ranges from 50 to 79%, while the 10‐year Kaplan–Meier freedom from mechanical failure is 64%. The artificial urinary sphincter is a reliable device with good outcomes. As expected with any prosthetic device, complications including mechanical failure, infection, erosion and recurrent incontinence remain significant concerns. Despite known complications, the patient satisfaction rates after artificial urinary sphincter implantation remain high. Appropriate patient counseling and adherence to surgical principles are imperative.  相似文献

Study Type – Symptom prevalence (non‐consecutive cohort)
Level of Evidence 3b

OBJECTIVE

To assess and identify the frequency and type of urinary incontinence (UI), as well as associated symptoms in persons with Prader‐Willi syndrome (PWS). PWS is characterized by mental retardation, short stature, obesity and hypogonadism. The behavioural phenotype includes eating problems, temper outbursts, affective disorders, stereotypies and speech abnormalities. UI is common in children with mental retardation in general, but has not been reported systematically in children with PWS so far.

MATERIALS AND METHODS

The Dutch version of the ‘Parental Questionnaire: Enuresis/Urinary Incontinence’ was completed by 118 parents of children with PWS. This questionnaire includes items referring to day‐ and night‐time wetting, toilet habits, observable voiding behaviours and reactions, urinary tract infections, stool habits and behavioural symptoms.

RESULTS

The rate of nocturnal enuresis in persons with PWS was 13.6% (16) at a mean age of 15.1 years. 3.8% (5) had additional daytime urinary incontinence, and 3.3% (4) had faecal incontinence. Lower urinary tract symptoms were commonly indicative of overactive bladder, dysfunctional voiding and postponement. Also, the rate of internalizing and externalizing behavioural problems was high.

CONCLUSION

Urinary incontinence is more common in persons with PWS than in typically developing children, adolescents and adults. As lower urinary tract symptoms are common, detailed assessment and specific treatment of UI should be part of the care of all persons with PWS.  相似文献
