Urinary Sphincter Disorders of Neurological Origin: Prognostic Aspects in the Neurology Department of the Ignace Deen National Hospital

Introduction: Complications of Urinary sphincter disorders of neurological origin can be life threatening. The objective of this study was to describe the prognosis of urinary sphincter disorders during neurological conditions. Methods: This was a six-month analytical study conducted at the neurological unit of the Hôpital national Ignace Deen. Including patients with urinary sphincter disorders following a neurological condition;Chi-square, Fischer, and Student’s t-tests were used for variables with a p value less than 0.10 and then included in a logistic model with a significance level set at 0.05 and a 95% confidence interval. Results: We collected 1081 patients among whom, 324 presented, that is to say a frequency of 30%, which concerned subjects aged 57.3 ± 16.4 years with a slight female predominance 50.3%. Urinary incontinence (80.6%) was associated with complications such as urinary tract infection with a high proportion of cerebral damage (92.3%). HIV infection (P = 0.015), bedsores (P = 0.049), and inhalation pneumonia (P = 0.001) were the main poor prognostic factors. Conclusion: Urinary sphincter disorders are elements of poor prognosis, both vital and functional, concerning elderly subjects with a predominance of urinary incontinence. HIV infection, bedsores, pneumopathy are poor prognostic factors.

Simultaneous penile prosthesis and male sling/artificia urinary sphincter

Erectile dysfunction （ED） and stress urinary incontinence （SUI） from urethral sphincteric deficiency is not an uncommon problem. The commonest etiology is intervention for localized prostate cancer and/or radical cystoprostatectomy for muscle invasive bladder cancer. Despite advances in surgical technology with robotic assisted laparoscopic prostatectomy and nerve sparing techniques, the rates of ED and SUI remain relatively unchanged. They both impact greatly on quality of life domains and have been associated with poor performance outcomes. Both the artificial urinary sphincter and penile prosthesis are gold standard treatments with proven efficacy, satisfaction and durability for end-stage SUI and ED respectively. Simultaneous prosthesis implantation for concurrent conditions has been well described, mostly in small retrospective series. The uptake of combination surgery has been slow due in part to technical demands of the surgery and to an extent, a heightened anxiety over potential complications. This paper aims to discuss the technical aspect of concurrent surgery for both disease entity and the current published outcomes of the various surgical techniques with this approach.

A comparison of artificial urinary sphincter outcomes after primary implantation and first revision surgery

Objective:The artificial urinary sphincter(AUS)is the gold standard for severe male stress urinary incontinence,though evaluations of specific predictors for device outcomes are sparse.We sought to compare outcomes between primary and revision AUS surgery for non-infectious failures.Methods:We identified 2045 consecutive AUS surgeries at Mayo Clinic(Rochester,MN,USA)from 1983 to 2013.Of these,1079 were primary AUS implantations and 281 were initial revision surgeries,which comprised our study group.Device survival rates,including overall and specific rates for device infection/erosion,urethral atrophy and mechanical failure,were compared between primary AUS placements versus revision surgeries.Patient follow-up was obtained through office examination,written correspondence,or telephone correspondence.Results:During the study period,1079(79.3%)patients had a primary AUS placement and 281(20.7%)patients underwent a first revision surgery for mechanical failure or urethral atrophy.Patients undergoing revision surgery were found to have adverse 1-and 5-year AUS device survival on Kaplan-Meier analysis,90%vs.85% and 74%vs.61%,respectively(p<0.001).Specifically,revision surgery was associated with a significantly increased cumulative incidence of explantation for device infection/urethral erosion(4.2%vs.7.5%at 1 year;p=0.02),with similar rates of repeat surgery for mechanical failure(p=0.43)and urethral atrophy(p=0.77).Conclusions:Our findings suggest a significantly higher rate of overall device failure following revision AUS surgery,which is likely secondary to an increased rate of infection/urethral erosion events.

Combination therapy for male erectile dysfunction and urinary incontinence

Urinary incontinence （UI） and erectile dysfunction （ED） are both very prevalent conditions. Insertion of an artificial urinary sphincter （AUS） and penile prosthesis （PP） is an effective and proven method of treatment for both conditions. With advancing age, as well as with increasing populations of patients radically treated for prostate cancer, the occurrence of both conditions found in the same patient is increasing. The purpose of this article was to analyze the available evidence for simultaneous surgical management of male ED and UI using prosthetic devices. The existing literature pertaining to dual implantation of AUS and PP was reviewed. The concomitant insertion of the PP with the male perineal sling was also considered. Concurrent ED and UI are increasingly seen in the post radical prostatectomy population, who are often younger and less willing to suffer with these conditions. Insertion of an AUS and PP, either simultaneously or as a two-stage procedure, appears to be a safe, efficacious and long-lasting method of treatment. The improvements in design of both the AUS and PP as well as the development of the single transverse scrotal incision have made simultaneous insertion of these prostheses possible. Dual implantation of the PP and male sling looks promising in a selected population. In conclusion, the insertion of the AUS and PP for the treatment of concurrent UI and ED is safe and effective. Simultaneous insertion of these prostheses in the same patient offers potential advantages in operative and recovery time and is associated with high patient satisfaction. Combination therapy should therefore be included in the arsenal of treatment of these conditions.
