CONTEXT: Abdominal sacrocolpopexy (ASC) represents the superior treatment for apical pelvic organ prolapse (POP) but is associated with increased length of stay, analgesic requirement, and cost compared with transvaginal procedures. Laparoscopic sacrocolpopexy (LSC) and robot-assisted sacrocolpopexy (RSC) may offer shorter postoperative recovery while maintaining equivalent rates of cure. OBJECTIVE: This review evaluates the literature on LSC and RSC for clinical outcomes and complications. EVIDENCE ACQUISITION: A PubMed search of the available literature from 1966 to 2013 on LSC and RSC with a follow-up of at least 12 mo was performed. A total of 256 articles were screened, 69 articles selected, and outcomes from 26 presented. A review, not meta-analysis, was conducted due to the quality of the articles. EVIDENCE SYNTHESIS: LSC has become a mature technique with results from 11 patient series encompassing 1221 patients with a mean follow-up of 26 mo. Mean operative time was 124min (range: 55-185) with a 3% (range: 0-11%) conversion rate. Objective cure was achieved in 91% of patients, with similar satisfaction rates (92%). Six patient series encompassing 363 patients treated with RSC with a mean follow-up of 28 mo have been reported. Mean operative time was 202min (range: 161-288) with a 1% (range: 0-4%) conversion rate. Objective cure rate was 94%, with a 95% subjective success rate. Overall, early outcomes and complication rates for both LSC and RSC appeared comparable with open ASC. CONCLUSIONS: LSC and RSC provide excellent short- to medium-term reconstructive outcomes for patients with POP. RSC is more expensive than LSC. Further studies are required to better understand the clinical performance of RSC versus LSC and confirm long-term efficacy. PATIENT SUMMARY: Laparoscopic and robot-assisted sacrocolpopexy represent attractive minimally invasive alternatives to abdominal sacrocolpopexy. They may offer reduced patient morbidity but are associated with higher costs. [less ▲]

Introduction and hypothesis: The objectives of this study were to evaluate the incidence of postoperative stress uri- nary incontinence (SUI) after laparoscopic sacrocolpopexy (LSCP) in women with negative preoperative prolapse re- duction stress testing (PPRST) and to identify associated risk factors. Methods: This was a retrospective cohort study comprising women who consecutively underwent double-mesh LSCP without concomitant SUI surgery after a negative PPRST at a tertiary referral center. Negative PPRST was defined by the absence of SUI during cough testing and urodynamic studies with prolapse reduction. Results: Fifty-five patients were assessed in the final analy- sis. No significant complication was encountered during and after LSCP. Mean follow-up was 25±11 (range 12–48) months. No patient developed recurrent pelvic organ pro- lapse (POP) or mesh erosion at last follow-up. Thirty (54.5 %) patients reported the symptom of SUI (subjective SUI) postoperatively, 13 (23.6 %) had a positive cough test (objective SUI) at last visit, and nine (16.4 %) underwent a sling procedure. In univariate analyses, advanced cystocele (stage 3–4) and a history of patient-reported SUI before surgery were associated with a higher risk of postoperative subjective and objective SUI after LSCP. Multivariate anal- yses identified preoperative SUI as the sole independent predictor of subjective SUI [risk ratio (RR04.03; 95% con- fidence interval (CI)01.16–14.09), objective SUI, (RR0 4.67; 95% CI01.14–19.23), and subsequent anti-SUI sur- gery after LSCP (RR06.17; 95% CI01.30–29.41). Conclusions: SUI is far from uncommon in women after LSCP despite negative PPRST, especially in those with advanced cystocele and a history of SUI preoperatively; after at least 1 year of follow-up, approximately one in six women eventually underwent a sling surgery. These data are useful for counseling patients. [less ▲]

Tension-free suburethral tapes have revolutionized the surgical treatment of female stress urinary incontinence (SUI). These tapes are inserted by way of a retropubic or transobturator route. The inside-out tension-free vaginal tape transobturator approach, or TVT-Obturator system (TVT-O®, Ethicon Women's Health and Urology, Somerville, NJ), was developed ten years ago with the aim of minimizing the risk of urinary tract injuries associated with retropubic and outside-in transobturator tapes while reproducibly ensuring minimal tissue dissection. Cadaveric studies have shown that the anatomical trajectory of the TVT-O tape is strictly perineal and courses away from neighboring obturator and pudendal neurovascular structures. Several meta-analyses have shown similar SUI cure rates after retropubic and transobturator tape procedures. Yet, the transobturator route may be associated with less voiding dysfunction, blood loss, bladder perforation, and shorter operating time. The original TVT-O procedure was modified with the aim of reducing the incidence of postoperative groin pain as well as the rather theoretical risk of obturator nerve injury. This modified procedure, named TVT-ABBREVO® (Ethicon Women's Health and Urology, Somerville, NJ), utilizes a shortened, 12-cm-long polypropylene tape. In addition, perforation of the obturator membrane with the scissors and guide is avoided in order to reduce the depth of lateral dissection, and consequently, to maximize securing of the tape within the obturator muscular/aponeurotic structures. In a comparative anatomical study, it was indeed observed that the shorter tape traversed less muscular structures (with no or only a minimal amount of tape lying in the adductor muscles) than its original counterpart, while still consistently anchoring in the obturator membrane at a similarly safe distance from the obturator canal. In a single-center randomized clinical trial, after a 3-year minimum follow-up, the modified TVT-O procedure with a shorter tape and reduced dissection was found to be as safe and efficient as the primal procedure for treating female SUI, with less severe and frequent groin pain in the immediate postoperative period.

BACKGROUND: Transobturator slings are currently promoted for the treatment of stress urinary incontinence (SUI) after radical prostatectomy (RP), but data on outcome remain limited. OBJECTIVE: To assess, at midterm, the efficacy and safety of the inside-out transobturator male sling for treating post-RP SUI and to determine factors associated with failure. DESIGN, SETTING, AND PARTICIPANTS: Prospective one-center trial involving 173 consecutive patients without detrusor overactivity, treated between 2006 and 2011 for SUI following RP. INTERVENTION: Placement of an inside-out transobturator sling. MEASUREMENTS: Baseline and follow-up evaluations included uroflowmetry and continence and quality-of-life (QoL) questionnaires. Cure was defined as no pad use and improvement as a number of pads per day reduced by >/=50% and two or fewer pads. Complications were recorded, and factors associated with treatment failure were evaluated. RESULTS AND LIMITATIONS: Preoperatively, 21%, 35%, and 44% of the patients were using two, three to five, and more than five pads per day, respectively. After a median follow-up of 24 mo (range: 12-60 mo), 49% were cured, 35% improved, and 16% not improved. QoL was enhanced (p<0.001), and 72% of patients were moderately to completely satisfied with the procedure. Maximum flow rates were slightly reduced (p=0.004); postvoid residual volumes were similar (p=0.097). Complications were urinary retention after catheter removal (15%), perineal/scrotal hematoma (9%), pain lasting >6 mo (3%), and sling infection (2%); all were managed conservatively. Severe SUI before sling surgery was not associated with a worse outcome, whereas obesity and a history of pelvic irradiation or bladder neck stenosis were independent risk factors of failure, with risk ratios of 7.9 (95% confidence interval [CI], 3.3-18.9), 3.3 (95% CI, 1.4-7.8), and 2.6 (95% CI, 1.1-6.5), respectively. CONCLUSIONS: The inside-out transobturator male sling is an efficient and safe treatment for post-RP SUI at midterm. Patients with prior pelvic irradiation may not be suitable candidates. [less ▲]

L’incontinence urinaire d’effort (IUE) féminine est principalement liée à une hypermobilité cervico-urétrale. Les bandelettes synthétiques placées sans tension sous l’urètre pour corriger cette hypermobilité ont révolutionné le traitement chirugical de l’IUE féminine depuis 15 ans. La technique rétropubienne, à savoir le “tension-free vaginal tape” (TVT), a été mise au point en 1996. Elle génère des taux de guérison de l’IUE élevés mais est associée à un risque de saignement intrapelvien et de perforation vésicale et intestinale. La voie transobturatrice de dedans en dehors, développée il y a huit ans dans notre Institution, connaît une diffusion mondiale. La technique est simple et reproductible et l’incidence des complications péri- et post-opératoires est réduite. Les taux de guérison de l’incontinence d’effort sont de près de 90% après 3-5 ans de suivi, similaires à ceux obtenus après pose d’une bandelette par voie rétropubienne. Nous avons récemment amélioré notre technique originale en utilisant une bandelette plus courte tout en réduisant la dissection nécessaire pour l’insertion de celle-ci. Après un suivi minimal d’un an, cette nouvelle technique apparaît aussi efficace et sécurisante que la technique transobturatrice ‘traditionnelle’ mais occasionne moins de douleurs de cuisse post-opératoires. Nous introduisons ainsi pour la première fois le concept du “midi sling” transobturateur. [less ▲]

Abstract: Chronic idiopathic penile edema (CIPE) is an exceptional entity with disabling persistent lymphedema of the penis, affecting accessorily the scrotum and the pubis. The onset presents with recurrent swelling of the external genitalia, regressing spontaneously. After 2-3 years the swelling becomes progressively persistent. Mictional and erectile dysfunctions are not uncommon. A thorough work-up including RX, ultrasound examination, CT scanning, MRI imaging, serology and extensive blood testing should be performed to exclude underlying causes, including neoplastic, infectious, vascular and inflammatory diseases. CIPE is associated with significant psychological and functional impact. Surgical correction is the sole therapeutic option. Three patients with CIPE and a review of the literature are presented in order to increase awareness of this rare condition. [less ▲]

ABSTRACT: Hodgkin lymphoma (HL) represents a category of lymphoid neoplasms with unique features, notably the usual scarcity of tumour cells in involved tissues. The most common subtype of classical HL, nodular sclerosis HL, characteristically comprises abundant fibrous tissue stroma. Little information is available about the protein composition of the stromal environment from HL. Moreover, the identification of valid protein targets, specifically and abundantly expressed in HL, would be of utmost importance for targeted therapies and imaging, yet the biomarkers must necessarily be accessible from the bloodstream. To characterize HL stroma and to identify potentially accessible proteins, we used a chemical proteomic approach, consisting in the labelling of accessible proteins and their subsequent purification and identification by mass spectrometry. We performed an analysis of potentially accessible proteins in lymph node biopsies from HL and reactive lymphoid tissues, and in total, more than 1400 proteins were identified in 7 samples. We have identified several extracellular matrix proteins overexpressed in HL, such as versican, fibulin-1, periostin, and other proteins such as S100-A8. These proteins were validated by immunohistochemistry on a larger series of biopsy samples, and bear the potential to become targets for antibody-based anti-cancer therapies. [less ▲]

INTRODUCTION AND HYPOTHESIS: The aim of this study is to compare a modified inside-out transobturator procedure with its original counterpart [inside-out transobturator (TVT-O)] for the treatment of female stress urinary incontinence (SUI). METHODS: A prospective, randomized trial in women suffering from SUI was used. The modified procedure consisted of a shorter tape whilst the scissors or guide no longer perforated the obturator membrane. The primary outcome was the resolution of subjective and objective SUI at 1 year. Secondary outcome measures included adverse events, quality of life measures, and groin pain. RESULTS: One hundred seventy-five patients were randomized. No intraoperative complications were recorded. The SUI cure rate was 91.7% versus 90.7% (original versus modified, respectively; p = 0.824). Incidence and intensity of groin pain was higher in the original TVT-O group on day 0 and 1 (p < 0.05), requiring more analgesics (p = 0.015) but not thereafter. CONCLUSIONS: At 1 year follow-up, the modified inside-out transobturator tape procedure was as efficient and safe as the original technique but associated with less immediate postoperative groin pain.

In the field of proteomics there is an apparent lack of reliable methodology for quantification of posttranslational modifications. Present study offers a novel post-digest ICPL quantification strategy directed towards characterization of phosphorylated and glycosylated proteins. The value of the method is demonstrated based on the comparison of two prostate related metastatic cell lines originating from two distinct metastasis sites (PC3 and LNCaP). The method consists of protein digestion, ICPL labeling, mixing of the samples, PTM enrichment and MS-analysis. Phosphorylated peptides were isolated using TiO(2), whereas the enrichment of glycosylated peptides was performed using hydrazide based chemistry. Isolated PTM peptides were analyzed along with non enriched sample using 2D-(SCX-RP)-Nano-HPLC-MS/MS instrumentation. Taken together the novel ICPL labeling method offered a significant improvement of the number of identified (∼600 individual proteins) and quantified proteins (>95%) in comparison to the classical ICPL method. The results were validated using alternative protein quantification strategies as well as label-free MS quantification method. On the biological level, the comparison of PC3 and LNCaP cells has shown specific modulation of proteins implicated in the fundamental process related to metastasis dissemination. Finally, a preliminary study involving clinically relevant autopsy cases reiterated the potential biological value of the discovered proteins. [less ▲]

Plusieurs essais randomisés et méta-analyses récentes ont montré que la voie transobturatrice est, à moyen terme, aussi efficace et plus sécurisante que la voie rétropubienne pour la mise en place d’une bandelette sous-urétrale pour traiter l’incontinence urinaire d’effort (IUE) féminine. En effet, la voie transobturatrice est associée à des taux de guérison subjective de l’IUE similaires (± 85-90%) mais à un risque moindre de saignement, de perforation vésicale et de troubles mictionnels postopératoires. La voie transobturatrice de dedans en dehors (‘Tension-free Vaginal Tape - Obturator’, TVT-O) a été développée en 2003 par Jean de Leval dans le but de réduire le risque de perforation de la vessie et de l’urètre tout en minimisant la dissection chirurgicale nécessaire pour insérer la bandelette. A ce jour, plus de 50 études cliniques, incluant 18 essais randomisés et 3 registres nationaux réalisés en France, Autriche et Norvège, ont largement démontré les excellents résultats à moyen terme (2-5 ans de suivi) de la technique TVT-O. Plus récemment, nous avons apporté deux modifications à la procédure TVT-O, à savoir l’utilisation d’une bandelette plus courte, de 12cm de long, insérée sans perforer la membrane obturatrice par les ciseaux ou le guide. Nos travaux anatomiques sur cadavres ont montré que cette bandelette plus courte est ancrée dans les muscles obturateurs et la membrane obturatrice mais évite dans une large mesure les muscles adducteurs. D’un point de vue clinique, nous avons comparé l’approche TVT-O originale à la version modifiée, potentiellement moins invasive, au travers d’un essai clinique prospectif randomisé. Les résultats de cet essai, présentés au congrès conjoint de l’International Continence Society (ICS) et de l’International Urogynecology Association (IUGA) à Toronto, ont montré qu’après suivi minimal d’1 an, les 2 approches génèrent des taux de guérison de l’IUE élevés et des taux de complications postopératoires très faibles, similaires pour les 2 procédures, la procédure modifiée étant néanmoins associée à une incidence et à une sévérité de douleurs de cuisse postopératoires immédiates significativement moindres.
