[Prevalence and initial management of overactive bladder in France: A cross-sectional study]. / Prévalence et prise en charge initiale de l'hyperactivité vésicale en France : une étude transversale.

AIMS: To determine the prevalence of overactive bladder (OAB) syndrome in France and gather data about initial patient trajectories in the healthcare system. METHODS: A dedicated questionnaire (41 questions) has been sent to a 12,000 sample of people representative of the global population. The following data were investigated: social and demographic features, medical history, Urinary Symptom Profile questionnaire, bother, history of symptoms, care seeking and treatments received. Patient were considered having OAB in case if presenting at least two episodes of urgency per week, or being under treatment of OAB. OAB prevalence was the main outcome, and associated factors were characterized by univariate and multivariate analysis. RESULTS: Based on 8842 available questionnaires, the global prevalence of OAB was estimated to be 14.4%. Prevalence was significantly higher in women, older age groups, as well as obesity, irritable bowel syndrome, urinary tract infections, enuresia, constipation, anxiety/depression, neurological diseases, sleep apnea syndrome, asthma, chronic obstructive pulmonary disease, diabetes and hypertension. Only 34.6% of patients with OAB had visited a health practitioner for this problem. General practitioners were most frequently implicated in patient primary care and evaluation. Seventy-two percent of patients with OAB had had additional investigations (mostly a urine culture) and only 6% of patients had to complete a bladder diary. The most frequent treatment option was oral antimuscarinics. Physical therapy and rehabilitation have been prescribed in 26% of cases, as well as dietary advice. CONCLUSIONS: OAB is a frequent syndrome. Its prevalence increases with age, and OAB frequently concern elderly frail people with many other associated diseases. LEVEL OF EVIDENCE: 3.

Is there a link between overactive bladder and the metabolic syndrome in women? A systematic review of observational studies.

OBJECTIVES: To conduct a systematic review to determine whether there is an association between metabolic syndrome (MetS) and lower urinary tract symptoms (LUTS) or overactive bladder (OAB) in women. METHODS: We systematically reviewed English language observational studies on the effect of MetS (or component factors) on the presence of OAB or LUTS in women. We searched PubMed, Web of Science and The Cochrane Library with no date restrictions, checked reference lists and undertook citation searches in PubMed and Google Scholar. Studies were assessed for risk of bias. Because of heterogeneity, results were not pooled, but are reported narratively. RESULTS: Of 27 included studies, only three looked at the link between MetS and OAB. The rest looked at links between OAB and components of MetS such as obesity or insulin resistance (n = 10), between MetS and urinary symptoms (n = 3) and between urinary symptoms and components of MetS, such as obesity (n = 14). Evidence is currently limited, but it does suggest that there may be important links between MetS and OAB and components of MetS such as obesity. CONCLUSIONS: The literature on MetS and OAB or LUTS in women is limited, and poor quality. However, the evidence available on obesity appears to support MetS as a contributor and predictor of LUTS in women. Many of the women with LUTS will be overweight and will have features of the MetS, if looked for. This provides not only an opportunity to encourage weight loss as an adjunct to therapy for the OAB symptoms but also a window of opportunity to address cardiovascular risk factors and prevent future cardiovascular morbidity and mortality.

[Fungal infections and ureteral material: How to manage?]. / Infections fongiques et matériel urétéral: quelle prise en charge?

INTRODUCTION: Urinary tract infections due to Candida species are mostly encountered in hospital environment. The management of candiduria on ureteral catheter is not consensual. The objective of our work was to make a review of medical literature related to definition, physiopathology, management and prevention of candiduria on ureteral catheter. MATERIAL AND METHODS: The research was made on Medline using the following keywords: Candida; fungal; urinary tract infection; ureteral stent; ureteric stent; double-J pigtail. RESULTS: The threshold defining candiduria is 10(5) CFU/mL. Candiduria corresponds to many different clinical presentations from colonization to candidemia. Species found are mostly Candida albicans (19-72%) and Candida glabrata (15.6-49.4%). The colonization of ureteral stent due to Candida is of 10% and comes with candiduria in 40% of the cases, due to the presence of biofilm. Prevention of infections on ureteral stents requires a regular change of material every 3-6 months depending on the patients risk groups. In case of symptomatic candiduria on ureteral stent, an anti-fungal therapy should be initiated 48 hours to 3 weeks before the change of the stent, in order to get a sterilization of urines and prevent the recolonization of the stent. Fluconazole is the drug of choice to use. CONCLUSION: Colonization of ureteral stents due to Candida is common and can be responsible of symptomatic infection. Anti-fungal therapy should be introduced before the change of the stent but a consensual duration of treatment before surgery is not found in the literature.

[Idiopathic overactive bladder and BOTOX(®): Literature review]. / Hyperactivité vésicale idiopathique et BOTOX(®): revue de la littérature.

AIM: Systematically review literature on the efficacy and tolerability of botulinum toxin A (onabotulinumtoxineA, BOTOX(®), Allergan, CA, USA) in refractory idiopathic overactive bladder (iOAB) METHODS: Pubmed search on the efficacy, toxicity and adverse events of onabotulinumtoxinA in clinical trials only with level 1 and 2 evidence. RESULTS: Eleven controlled randomised trials have been selected, of which 3 phase III trials. The studies published data of 1008 patients with refractory iOAB treated with onabotulinumtoxineA. In the phase II and III trials, doses from 50 U to 300 U have been evaluated; more than half of the patients (n = 676) with 100 U. In the 2 main phase III trials, onabotulinumtoxinA has demonstrated to be more efficient compared to placebo on continence, symptoms and quality of live (QoL). Urodynamic results, reported in the phase II trials, demonstrated higher changes compared to placebo only from dose 100 U on, although not always significant. Adverse events (urinary retention, dysuria, urinary tract infection) were easily treated and did not influence patient's QoL. CONCLUSION: Intradetrusor injections of onabotulinumtoxinA (BOTOX(®)), a minimally-invasive procedure, seem to be efficient and well tolerated in the treatment of refractory iOAB.

Efficacy and safety of repeated dosing of netupitant, a neurokinin-1 receptor antagonist, in treating overactive bladder.

AIM: NK-1 receptors in sensory nerves, the spinal cord and bladder smooth muscle participate in complex sensory mechanisms that regulate bladder activity. This study was designed to assess the efficacy and safety of a new NK-1 receptor antagonist, netupitant, in patients with OAB. METHODS: This was a phase II, multicenter, double-blind study in which adults with OAB symptoms >6 months were randomized to receive 1 of 3 doses of netupitant (50, 100, 200 mg) or placebo once daily for 8 weeks. The primary efficacy endpoint was percentage change from baseline in average number of daily micturitions at week 8. Urinary incontinence, urge urinary incontinence (UUI), and urgency episodes were also assessed. RESULTS: The primary efficacy endpoint was similar in the treatment groups (-13.85 for placebo to -16.17 in the netupitant 200 mg group) with no statistically significant differences between netupitant and placebo. The same was true for most secondary endpoints although a significant difference for improvement in UUI episodes and a trend for the greatest decrease in urgency episodes were seen in the netupitant 100 mg group. Netupitant was well tolerated with most treatment emergent adverse events (AEs) being mild. While the overall incidence of AEs increased with netupitant dose, there was no evidence for this dose dependency based on relationship to treatment, intensity, or time to onset. CONCLUSIONS: The study failed to demonstrate superiority of netupitant versus placebo in decreasing OAB symptoms, despite a trend favoring netupitant 100 mg. There were no safety concerns with daily administration of netupitant over 8 weeks.

Guidelines for practical usage of botulinum toxin type A (BoNTA) for refractory idiopathic overactive bladder management: Translation of French recommendations.

OBJECTIVE: Provide guidelines for practical usage of botulinum toxin type A (BoNTA) for refractory idiopathic overactive bladder management. PATIENTS AND METHODS: Guidelines using formalized consensus guidelines method. These guidelines have been validated by a group of 13 experts quoting proposals, subsequently reviewed by an independent group of experts. RESULTS: In the case of patients with urinary tract infection, it must be treated and injection postponed. Before proposing an injection, it is recommended to ensure the feasibility and acceptability of self-catheterisation by patient. The injection can be performed after local anesthesia of the bladder and urethra (lidocaine), supplemented where necessary by nitrous oxide inhalation and sometimes under general anesthesia. Injection is performed in the operating room or endoscopy suite. The bladder should not be too filled (increased risk of perforation). Treatment should be applied in 10 to 20 injections of 0.5 to 1 mL homogeneously distributed in the bladder at a distance from the urethral orifices. It is not recommended to leave a urinary catheter in place except in cases of severe hematuria. The patient should be monitored until resumption of micturition. After the first injection, an appointment must be scheduled within 3 months (micturition diary, uroflowmetry, measurement of residual urine and urine culture). Performance of self-catheterisation should be questioned in the case of a symptomatic post-void residual and/or a residue>200 mL. A new injection may be considered when the clinical benefit of the previous injection diminishes (between 6 and 9 months). A period of three months must elapse between each injection. CONCLUSIONS: Implementation of these guidelines may promote best practice usage of BoNTA with optimal risk/benefit ratio.

Repeat mid-urethral sling for recurrent female stress urinary incontinence.

INTRODUCTION AND HYPOTHESIS: The aim of the study was to assess the effectiveness of repeat mid-urethral sling after a failed primary sling for stress urinary incontinence. METHODS: A total of 112 women with recurrent stress incontinence after primary mid-urethral sling underwent a repeat procedure between 2000 and 2011. All patients had a preoperative clinical and urodynamic evaluation. Outcomes were divided into three groups: cured (no more leaks), improved (decrease of leaks), or failed. RESULTS: All patients had urethral hypermobility and 12.9 % had intrinsic sphincter deficiency [maximum urethral closure pressure (MUCP) ≤ 20 cmH2O]. Median MUCP was 41 cmH20. Overactive bladder was found in 5.7 % of women. The second sling placed was one of the following: retropubic Tension-free Vaginal Tape (49 %), transobturator tape (48 %), or mini-sling (3 %). No intraoperative morbidity was reported. After the second sling was placed, 68 (60.7 %) patients were subjectively cured and 18 (16.1 %) improved (76.8 % success overall) with a mean follow-up of 21 months. Success rates were 72.2 and 81.8 % for transobturator and retropubic slings, respectively, with no significant difference. Multivariable analysis showed higher odds of cure and improvement with the retropubic approach after adjusting for MUCP. Late complication rates were comparable to those observed after a first sling. Urodynamic parameters were not associated with postoperative success. CONCLUSIONS: Repeat mid-urethral sling for recurrent female stress urinary incontinence is nearly 77 % successful in a group of patients with persistent urethral hypermobility. A retropubic approach might be preferred for patients with low urethral closure pressures.

[Pharmacological treatment of idiopathic overactive bladder: a literature review]. / Traitements pharmacologiques de l'hyperactivité vésicale idiopathique: revue de la littérature.

OBJECTIVE: To depict the recent advances in the field of pharmacological treatment of idiopathic overactive bladder (iOAB). METHODS: A literature search was conducted, using the PubMed/Medline database. Articles were included if published as full papers, after 2008 and before September 2012, and focused on recent pharmacologic treatment options for iOAB management. Publications having the highest level of evidence have been analyzed to summarize the available evidence, prioritizing the treatments available in France. RESULTS: Some meta-analyses have been published between 2008 and 2012, gathering information about 82 level 1 evidence studies about efficacy and safety of anticholinergics. According to the most recent meta-analysis, anticholinergics have proved their efficacy for iOAB management, reducing the number of micturitions per day by up to 1.59, the number of incontinence episodes per day by up to 0.7, the number of urgency episodes by up to 1.7, the number of urgency incontinence episodes by up to 2.25, and the number of nocturnal voids by up to 0.24. Safety profile was good, especially for solifenacin and fesoterodine, supported by strong scientific evidence. However, data were limited to short-term follow-up, with no anticholinergic drug superior to another. Few data were available about observance, risk factors for failure and results in specific populations. Anticholinergics can be used safely for management of lower urinary tract symptoms in men, but their role is still to be determined. Data about innovative drugs were still preliminary. CONCLUSIONS: Anticholinergics are a valuable option for management of iOAB, and have a growing role in management of lower urinary tract symptoms in men without bladder outlet obstruction.

[Mini-sling for management of stress urinary incontinence in women: a literature review]. / Mini-bandelettes pour le traitement de l'incontinence urinaire d'effort féminine : revue de la littérature.

AIM: To conduct a review about the use of single incision mini-slings (SIMS) to manage non-neurogenic stress urinary incontinence in women. METHODS: Literature search in Pubmed/MEdline database until june 2013. TVT-Secur™ was excluded because this device is not anymore marketed. RESULTS: Ajust™ and Mini-Arc™ were the two main SIMS evaluated in the literature. Studies about Mini-Arc™ generated heterogeneous results, with a success rate between 44% and 91% after 1 year. Ajust™ was the most promising device with 80% efficacy after mid-term follow-up. All evaluated SIMS had a low rate of immediate complications. Two randomized controlled trials comparing SIMS and traditional mid-urethral slings were identified, as well as one meta-analysis; they all concluded to non-superiority or inferiority for the mini-sling versus traditional slings. CONCLUSION: Due to short follow-up, limited evidence and heterogeneous data, SIMS are not yet standard of care and further research is warranted.

[Guidelines for practical usage of botulinum toxin type A (BoNTA) for refractory idiopathic overactive bladder management]. / Recommandations pour l'utilisation de la toxine botulinique de type A (Botox®) dans l'hyperactivité vésicale réfractaire idiopathique.

[Metabolic syndrome and urinary disorders]. / Troubles vésicosphinctériens et syndrome métabolique.

OBJECTIVE: The goal of this article is to review and discuss the various and numerous links between metabolic syndrome (MetS) and bladder, specially overactive bladder syndrome. METHODS: Pubmed/Medline analysis, without date or language limits, was conducted using the following keywords: "metabolic syndrome" and "bladder (or "incontinence" or "overactive bladder"). All types of papers were analysed (117). RESULTS: MetS is defined as the presence of three or more of the following five characteristics: 1) waist circumference greater than 102 cm; 2) systolic blood pressure 130 mmHg or greater or diastolic blood pressure 85 mmHg or greater, or antihypertensive medication use; 3) HDL cholesterol less than 40 mg/dL or lipid medication use; 4) self- reported type 2 diabetes or increased blood sugar or diabetes medication use; 5) triglycerides greater than 150 mg/dL. In regard of epidemiolgy, there is a strong correlation between MetS and overactive bladder. Pathophysiological mechanisms to explain the relationship of storage symptoms rather than voiding phase symptoms with MetS include the influence of sustained hyperglycemia on the viability of parasympathetic neurons in the pelvic ganglion. A link or overlaps between MetS and alteration of autonomic nervous system can be hypothezised. CONCLUSION: Links between Mets and urinary disorders are frequent and common pathophysiological factors can be frequently observed, particularly autonomic nervous system alterations.

[Salvage therapy with artificial urinary sphincter after Advance™ male sling failure for post-prostatectomy incontinence: a first clinical experience]. / Thérapie de sauvetage par implantation d'un sphincter artificiel urinaire après échec de bandelette Advance™ pour incontinence urinaire après prostatectomie : une expérience monocentrique.

OBJECTIVES: To assess the clinical outcome following artificial urinary sphincter (AUS) implantation after failure of Advance™ sub-urethral male sling for post-prostatectomy incontinence (PPI). METHODS: A prospective evaluation was conducted about consecutive patients who received an AUS after failure of Advance™ therapy in one tertiary reference center. Evaluation included medical history, pad use and operative data (duration, cuff size, technical difficulties). Follow-up was scheduled at 1, 6, 12 months and yearly thereafter. Clinical outcome was evaluated by pad use, patient global impression of improvement (PGI-I) scale and assessment of side effects. Cure was defined as no pad usage. RESULTS: Twelve patients were included in this evaluation. Median follow-up was 20 months (12-43). No patient was lost to follow-up. Four patients had a history of radiation therapy and all patients had mild or moderate PPI with previous failed Advance™ surgery. Median (range) operative time was 47 minutes (40-60). No technical problem occurred during AUS implantation. Hospital stay duration and catheterization duration were respectively 2 days and 24 hours in all but one case. At last follow-up, 10/12 patients (83%) were cured and fully satisfied. Two were improved, wearing only one pad per day. Postoperative complications were noted in two cases (17%) (one case of cutaneous erosion and one case of superficial iliac wound infection). CONCLUSIONS: AUS implantation is feasible in patients who have undergone Advance™ male sling implantation. Mid-term results of this procedure are comparable to those obtained after first line AUS implantation.

[Predictive value of the penile cuff-test for the assessment of bladder outlet obstruction in men]. / Valeur prédictive du cuff-test dans le diagnostic de l'obstruction sous-vésicale chez l'homme.

PURPOSE: To assess the diagnostic performances and the acceptability of the penile cuff test (PCT) which is a non invasive method for the evaluation of bladder outlet obstruction (BOO), in comparison with the pressure flow study (PFS), the actual gold-standard. MATERIAL: Monocentric prospective study comparing the following subsets: "obstructed", "not obstructed" or "equivocal", deduced from PFS vs PCT, in 30 consecutive patients presenting with lower urinary tract symptoms. For the PCT, a cuff placed around the penis inflated automatically during the micturition, until flow rate interruption. The interruption cuff pressure revealed the isovolumetric bladder pressure (Pcuff-int). The data collected - Pcuff-int and maximum flow rate - were automatically reported on ICS modified nomogram. RESULTS: With the PFS, 11 patients (39%) were classified "obstructed", six patients (22%) "non-obstructed" and 11 patients (39%) "equivocal". In 61% cases, the patient was classified in the same category by both techniques. The "obstructed positive predictive value" of the PCT was 82% and the "non-obstructed-equivocal negative predictive value" was 88%. The median acceptability visual analogic scale score was 1/10 (0-3) for the PCT whereas it was 5/10 (2-10) for the PFS. This difference was statistically significant (p=0.004). CONCLUSION: The PCT was a reliable non-invasive tool for the diagnosis of BOO in male, in comparison with PFS. The predictive values of the PCT were relevant and its tolerance was better than PFS.

Genetic susceptibility to urinary incontinence: implication of polymorphisms of androgen and oestrogen pathways.

PURPOSE: Although existence of genetic factors predisposing to urinary incontinence in women is widely admitted, precise molecular and genetic variations implicated are still unknown. Given the established influence of steroids metabolism in incontinence, we studied the correlation between polymorphisms of genes of oestrogen/androgen pathways and urinary incontinence in women, in order to raise evidence of genetic susceptibility. METHODS: A case-control study included 121 cases and 66 controls. Age, familial history of incontinence, gynaecologic history and age of menopause were collected. Patients were classified into three groups: control, urge urinary incontinence (UUI), stress urinary incontinence (SUI). Genetic polymorphisms were determined after amplification by PCR for the following genes: CYP-19, CYP17, androgen receptor (AR) and oestrogen receptor (ESR-1). Statistical analysis was performed to study correlation between genotype and presence of a subtype of incontinence. RESULTS: A total of 187 patients were analysed: 66 were controls, 30 presented UUI and 107 presented SUI. Patients presenting incontinence had significantly more often familial history of incontinence than controls. AR polymorphism (combination of 2 alleles containing more than 21 CAG repeats) is significantly associated with UUI (P = 0.02). Polymorphisms of ESR-1, CYP17 and CYP19 were not associated with any subtype of urinary incontinence. CONCLUSIONS: This study shows that AR polymorphism is linked to genetic susceptibility to urinary incontinence. This result suggests that this disease is partly gene-related and encourages larger studies to explore the genetics factors of urinary incontinence.

[Initial experience combinating transobturator male sling and penile implant after radical prostatectomy]. / Chirurgie combinée par bandelette transobturatrice Advance et prothèse pénienne après prostatectomie totale: une première expérience.

PURPOSE: Stress urinary incontinence (SUI) and erectile dysfunction (ED) are two major complications following radical prostatectomy (RP). In case of failure of medical treatment, Advance™ retrourethral male sling and penile implant are validated options to manage respectively SUI and ED. Our goal was to assess the feasibility and results of the combination of these two devices. PATIENTS AND METHODS: Four patients were treated for SUI and DE following RP in our institution by retrourethral sling and penile prosthesis, after failure of medical management. Each patient was preoperatively evaluated by age, complete medical history, ASA score, endoscopy, pad-test, and urodynamics. The first two patients were implanted with the two devices in a two-stage procedure: retrourethral sling then penile prosthesis for one, and penile prosthesis then retrourethral sling for the other. The two other patients underwent a one-stage procedure: one received the two devices, and the other had retrourethral sling implantation and replacement of a penile prosthesis. Post-operative follow-up was focused on complications and efficacy (evaluated by pad use and PGI-I questionnaire for continence, and patient auto-evaluation for sexual function). RESULTS: No perioperative complication occurred. After a minimum of 6 months follow-up, all the four patients were pad-free with no leakage reported, feeling very much better after the procedure according to the PGI-I. The four patients were fully satisfied of the penile implant device. CONCLUSIONS: According to our initial experience, surgery combining the transobturator Advance male sling and a penile prosthesis is feasible, successively or simultaneously, and leads to excellent functional results with no complications.

[Evaluation of urologic activity in ambulatory surgery: a single centre experience]. / Évaluation de la pratique de la chirurgie ambulatoire en urologie: expérience d'un centre.

OBJECTIVE: Ambulatory surgery is an alternative to traditional hospitalisation and an opportunity for savings for the healthcare system. Here, we analyze our experience in outpatient surgery in urology over a year. MATERIAL: A prospective database concerning outpatient activity was established in 2009, gathering age, ASA score, type of intervention, discharge and recovery for each patient. An individual questionnaire was sent retrospectively in February 2010, to collect data about history of outpatient surgery, overall satisfaction, preference for traditional hospitalization and emergency department visits within 48 hours after surgery. RESULTS: In 2009, 465 patients aged of 52±16 years (15-98) underwent urologic surgery on an outpatient basis. Median ASA score was 2 (1-3). Types of intervention were mainly endo-urology (44.5%), surgery for urinary incontinence (32.5%), and circumcision (12.3%). The postoperative hospitalization rate was 4.5%. The questionnaire response rate was 28%. Forty-six percent of the patients had already been supported in ambulatory, overall satisfaction was 3.3 out of 4 (±1.06) and 24% of patients would have preferred a traditional hospitalization. 11% of patients required emergency department care within 48 hours whatever the surgery undergone. CONCLUSION: An important part of urological procedures has been done on an outpatient basis without compromising quality of care and patient satisfaction.

[Flexible ureteroscopy in the treatment of kidney stone between 2 and 3 cm]. / Urétéroscopie souple dans le traitement des calculs du rein de 2 à 3cm.

PURPOSE: Our aim was to evaluate the outcome of flexible ureteroscopy (F-URS) with Holmium Laser as a minimal invasive procedure for kidney stone between 2 and 3 cm in diameter. MATERIAL: We prospectively evaluated 101 patients (103 kidney units) with kidney stone between 2 and 3 cm, who underwent flexible ureteroscopy (F-URS) with Holmium Laser. Patient age, sex, body mass index (BMI), stone size, stone composition, associated lower calyx stone, prestenting, congenital abnormalities, urological history, operating time and complications were evaluated. The outcome was determined at 4 weeks on plain radiograph (KUB) and noncontrast CT scan (NCCT) or by endoscopic second look if needed. Ureteroscopy success rate was defined as stone free (SF) or remaining fragments (RF) less than 3 mm. RESULTS: After F-URS session we obtained a stone free status in 35 kidney units (34%), residual fragment less than 3mm in 30 kidney units (29.1%) and 38 kidney units (36.9%) with significant residual fragment. F-URS success rate was 89.3% and 97.1% after second and third session, respectively. CONCLUSIONS: F-URS with Holmium Laser is a very effective and safe technique in treating kidney stone. This technique should be proposed to patient with kidney stone between 2 and 3 cm as one of the treatment modalities, F-URS offers excellent results, low rate of complications and short hospital stay. Patients should be informed about staged therapy.

[Prospective evaluation of intrasphincteric injections of autologous muscular cells in patients with stress urinary incontinence following radical prostatectomy]. / Évaluation prospective du traitement de l'incontinence urinaire post-prostatectomie par injections intrasphinctériennes de cellules musculaires autologues.

PURPOSE: Cell therapy for urinary incontinence management has been experienced in animals with encouraging results, but studies in human beings are lacking. Our primary objective was to assess the safety of intrasphincteric injections of autologous muscular cells in patients with postprostatectomy incontinence (PPI). Secondary objectives focused on complications efficacy. METHODS: We conducted an open, prospective study in a single center on 12 patients presenting PPI. Patients underwent intrasphincteric injections of autologous muscular cells isolated from a biopsy of deltoid muscle. The primary endpoint was the Q(max) variation at the three month visit in order to assess potential bladder outlet obstruction. Secondary endpoints assessed side effects and efficacy parameters based on symptoms, quality of life score, voiding diary, pad-test, and urethral pressure profile at one, two, three, six and 12 months after injection. RESULTS: No immediate complication occurred and no significant variation was noted on Q(max). The only side effects possibly product-related were three cases of urinary tract infection treated by antibiotics. An acceptable safety and tolerability of the procedure whatever the injected dose of muscular cells was demonstrated. Results on efficacy after one year were heterogeneous, with 4/12 patients describing reduced urine leakage episodes, 1/12 patient presenting increased maximal closure pressure, and 8/12 patients showing improvement on pad-test. CONCLUSIONS: Cell therapy consisting of intrasphincteric injections of autologous muscular cells in patients with PPI was a feasible and safe procedure. The results point out that some subjects may positively respond to this procedure, but clinical efficacy remains to be confirmed.
