[Urinary cytology for the detection of urothelial lesions]. / Rôle de la cytologie urinaire dans le dépistage des lésions urothéliales.

Urine cytology is a long-used technique for the detection of high grade neoplastic urothelial lesions. Since 2016, «The Paris System¼ classification has revolutionized this field by introducing a standardized terminology widely adopted by cytopathologists and urologists. In this article, we explain this classification and discuss its impact on the clinical management of patients with urothelial lesions, as well as its role in the secondary prevention of these lesions.

La cytologie urinaire est une technique utilisée depuis longtemps dans la détection des lésions urothéliales tumorales de haut grade. Depuis 2016, la classification «The Paris System¼ a révolutionné ce domaine en introduisant une terminologie standardisée largement adoptée par les cytopathologistes et les urologues. Dans cet article, nous expliquons cette classification et discutons de son impact sur la prise en charge clinique des lésions urothéliales, ainsi que son rôle dans la prévention secondaire de ces lésions.

[The place of radiation therapy following radical prostatectomy in 2024]. / La place de la radiothérapie après une prostatectomie dans les cancers de la prostate en 2024.

Radiation therapy after prostatectomy for a prostate cancer is a recommended treatment in case of biochemical relapse (rising PSA) following surgery. Controversies regarding its optimal use, delivery, and toxicities are often discussed, not only within scientific congresses but also during multidisciplinary oncological boards. This article aims at making an assessment of up-to-date knowledge and recommendations to guide decision making regarding the treatments of patients with prostate cancer.

La radiothérapie après prostatectomie pour un cancer de prostate est un traitement recommandé en cas de «récidive biochimique¼ (ré-élévation du PSA) après l'opération. Des controverses quant à son utilisation optimale, sa réalisation, et ses toxicités font régulièrement l'objet de discussio, que ce soit au sein des sociétés scientifiques ou lors des concertations oncologiques multidisciplinaires. Cet article a pour but de faire l'état des lieux des connaissances actuelles et des recommandations existantes afin de guider nos réflexions et prises de décision concernant les traitements des patients présentant un cancer de la prostate.

[Ulcerative Zoon's balanitis]. / Balanite de Zoon ulcérée.

Zoon's balanitis is a rare genital dermatosis of unknown etiology, usually presenting as a red-orange macule or plaque with a «cayenne pepper¼ appearance on the glans and/or foreskin. Unfortunately, atypical presentations are not uncommon, including vegetating or ulcerative lesions. Usually, it affects middle-age to older uncircumcised men. Although it is a benign pathology, Zoon's balanitis may be superimposed on another inflammatory or neoplastic dermatosis. As topical treatments are generally non satisfactory and relapses are usual on treatment with-drawal, circumcision remains an interesting option with usually a rapid and complete remission of the symptoms.

La balanite de Zoon est une dermatose génitale peu fréquente d'étiologie inconnue, se présentant habituellement par une macule ou une plaque de couleur rouge- orange avec un aspect en «poivre de cayenne¼, sur le gland et/ou le prépuce. Néanmoins, des formes atypiques, végétantes ou ulcérées, sont possibles. Elle touche plus souvent l'homme d'âge moyen à avancé et non circoncis. Il s'agit d'une pathologie bénigne, mais qui peut se surajouter à d'autres dermatoses inflammatoires ou néoplasiques. Les traitements topiques ne sont pas très efficaces et entraînent généralement une récidive à l'arrêt, tandis que la circoncision permet souvent une disparition rapide et complète des symptômes.

[The overactive bladder syndrome]. / Le syndrome d'hyperactivité vésicale.

The overactive bladder (OAB) syndrome is defined as urinary urgency, usually with urinary frequency and nocturia, with or without urgency urinary incontinence. It significantly impacts patients' quality of life and represents a significant public health issue. Treatment options include conservative and hygienic measures, pharmacological treatments and surgery.

Le syndrome d'hyperactivité vésicale (SHV) est défini par la survenue d'urgenturie avec ou sans incontinence urinaire, habituellement associée à une pollakiurie ou à une nycturie. Il impacte significativement la qualité de vie des patients et représente un réel problème de santé publique. Les options thérapeutiques incluent des mesures conservatrices et hygiéno-diététiques, des traitements médicamenteux et chirurgicaux.

Parastomal hernia after radical cystectomy with ileal conduit diversion: a narrative review.

Radical cystectomy (RC) with ileal conduit urinary diversion has become a common surgical procedure. Stomal complications and particularly parastomal hernia (PH) are the most frequent complications and causes of reintervention after RC with ileal conduit urinary diversion. PH is usually asymptomatic. When PH increases in size and becomes symptomatic, it clearly impairs patients' quality of life in terms of physical limitation, mental distress and social interaction. The aim of this article was to review the current knowledge on PH after RC with ileal conduit urinary diversion, regarding its natural history, risk factors, prevention and surgical management. There is no strong recommendation on the ideal surgical technique for repair of PH after RC, but laparoscopic Sugarbaker or Sandwich techniques with non-absorbable meshes are emerging as the preferred modern means of PH repair. Techniques for prevention and repair of PH after RC need to be specifically evaluated in future prospective studies.

Lipidomic Profiling of Clinical Prostate Cancer Reveals Targetable Alterations in Membrane Lipid Composition.

Dysregulated lipid metabolism is a prominent feature of prostate cancer that is driven by androgen receptor (AR) signaling. Here we used quantitative mass spectrometry to define the "lipidome" in prostate tumors with matched benign tissues (n = 21), independent unmatched tissues (n = 47), and primary prostate explants cultured with the clinical AR antagonist enzalutamide (n = 43). Significant differences in lipid composition were detected and spatially visualized in tumors compared with matched benign samples. Notably, tumors featured higher proportions of monounsaturated lipids overall and elongated fatty acid chains in phosphatidylinositol and phosphatidylserine lipids. Significant associations between lipid profile and malignancy were validated in unmatched samples, and phospholipid composition was characteristically altered in patient tissues that responded to AR inhibition. Importantly, targeting tumor-related lipid features via inhibition of acetyl-CoA carboxylase 1 significantly reduced cellular proliferation and induced apoptosis in tissue explants. This characterization of the prostate cancer lipidome in clinical tissues reveals enhanced fatty acid synthesis, elongation, and desaturation as tumor-defining features, with potential for therapeutic targeting. SIGNIFICANCE: This study identifies malignancy and treatment-associated changes in lipid composition of clinical prostate cancer tissues, suggesting that mediators of these lipidomic changes could be targeted using existing metabolic agents.

Open and Laparoscopic Partial Nephrectomy: Comparison and Validation of Preoperative Scoring Systems, Including PADUA, RENAL, ABC Nephrometric Scores and Perinephric Fat Evaluation with Mayo Adhesive Probability Score.

PURPOSE: To evaluate potential associations between 4 nephrometric scoring systems, namely the PADUA (preoperative aspects and dimensions used for anatomical classification), RENAL (radius endophytic/exophytic nearness anterior posterior location), ABC (arterial-based complexity), and MAP (Mayo adhesive probability) scores and their individual components, with surgical and oncological outcomes of patients undergoing a partial nephrectomy. MATERIALS AND METHODS: A consecutive, monocentric cohort of partial nephrectomy patients was retrospectively analyzed. PADUA, RENAL, ABC and MAP nephrometry scores were determined from preoperative axial images. Unadjusted and adjusted associations between overall scores, individual components, surgical approach, complications and oncological outcomes were determined using univariate and multivariate logistic regressions. RESULTS: A total of 189 partial nephrectomies were performed in 181 patients, via an open or a laparoscopic approach. Among scoring systems, only the MAP classification, which assesses adherent perinephric fat, was associated with severe surgical complications as well as with operative time (p<0.05). Among all components of the PADUA and RENAL scores, only proximity of the tumor to the collecting system was associated with overall surgical complication rates, while the diameter of the tumor influenced the operative time (p<0.05). The ABC score was not relevant. Male gender, antiplatelet therapy, and a laparoscopic approach were associated with higher overall surgical complication rates (p<0.05). The number of oncologic recurrences during follow-up was too low to run statistical analyses. CONCLUSION: Nephrometry scores could be simplified to predict surgical complications after partial nephrectomy. In this framework, adherent perinephric fat seemed to be strongly associated with an increased risk of surgical complications.

Interobserver agreement of [68Ga]Ga-PSMA-11 PET/CT images interpretation in men with newly diagnosed prostate cancer.

BACKGROUND: Prostate-specific membrane antigen (PSMA) ligand PET/CT has already provided promising results in prostate cancer (PC) imaging, yet simple and reproductible reporting criteria are still lacking. This study aimed at retrospectively evaluating interobserver agreement of [68Ga]Ga-PSMA-11 PET/CT images interpretation according to PC molecular imaging standardized evaluation (PROMISE) criteria and reproducibility of PSMA reporting and data systems (RADS). METHODS: Forty-three patients with newly diagnosed, histologically proven intermediate- or high-risk PC, eligible for radical prostatectomy and who underwent [68Ga]Ga-PSMA-11 PET/CT before surgery were retrospectively included. Three nuclear medicine physicians (2 experienced and 1 resident) independently reviewed PET/CT images. Interpretation of [68Ga]Ga-PSMA-11 PET/CT images was based on PROMISE criteria including miTNM staging and lesions miPSMA expression score visual estimation and PSMA-RADS version 1.0 for a given scan. Readers' agreement was measured using Krippendorff's coefficients RESULTS: Agreement between observers was almost perfect (coefficient ≥ 0.81) for miM; it was substantial (coefficient ≥ 0.61) for the following criteria: miT, miN, PSMA-RADS, and miPSMA expression score of primary PC lesion and metastases. However, agreement was moderate (coefficient = 0.41-0.60) for miPSMA score of positive lymph nodes and for detection of PC primary lesion. CONCLUSION: Visual interpretation of [68Ga]Ga-PSMA-11 PET/CT images in patients with newly diagnosed PC in a clinical setting leads to at least substantial agreement for PROMISE criteria and PSMA-RADS classification except for PC primary lesion detection and for miPSMA expression scoring of positive lymph nodes that might have been hampered by the interindividual variability of reference organs PSMA expression.

A noninvasive urine-based methylation biomarker panel to detect bladder cancer and discriminate cancer grade.

BACKGROUND: Highly sensitive and specific urinary biomarkers for the early detection of bladder cancer (BC) to improve the performance of urinary cytology are needed. OBJECTIVE: To investigate the usefulness of methylation markers in voided urine to identify BC presence and grade. DESIGN, SETTINGS, AND PARTICIPANTS: Using genome-wide methylation strategies in Toronto, Canada and Liège, Belgium, we have identified differentially methylated genes (TWIST1, RUNX3, GATA4, NID2, and FOXE1) in low-grade vs. high-grade BC tissue and urine. We accrued urine samples from 313 patients using a 2:1 ratio in a case-control setting from Toronto, Canada, Halifax, Canada, and Zurich, Switzerland. We studied the usefulness of these 5 methylated genes to identify BC and discriminate cancer grade in voided urine specimens. Urinary cell sediment DNA was evaluated using qPCR-based MethyLight assay. Multivariable logistic regression prediction models were created. RESULTS AND LIMITATIONS: We included 211 BC patients (180 nonmuscle invasive) and 102 controls. In univariate analyses, all methylated genes significantly predicted BC vs. no BC, and high grade vs. low grade (all P < 0.05). In multivariable analysis, NID2, TWIST1, and age were independent predictors of BC (all P < 0.05). Sensitivity of NID2 and TWIST1 to predict BC and BC grade was 76.2% and 77.6%, respectively, whereas specificity was 83.3% and 61.1%, respectively. Multivariable models predicting BC overall and discriminating between high-grade and low-grade BC reached area under the receiver operating characteristics curves of 0.89 and 0.78, respectively. CONCLUSIONS: This multi-centric study in a real life scenario (different countries, techniques, and pathologists) supports the promise of epigenetic urinary markers in noninvasively detecting BC. With sensitivities and specificities in the range of 80%, the overall performance characteristics of this panel of methylated genes probably does not allow such signature to significantly alter clinical care at this stage but is worth further studying for instance in BC surveillance or screening in high-risk populations.

Outcomes after salvage radical prostatectomy and first-line radiation therapy or HIFU for recurrent localized prostate cancer: results from a multicenter study.

INTRODUCTION: Despite no consensus on the optimal management of recurrent prostate cancer after primary radiation or HIFU therapy, salvage prostatectomy (sRP) is reserved for only 3% of patients because of technical challenges and frequent post-operative complications. We assessed outcomes after sRP in a series of patients with localized PCa and that had received radiation therapy or HIFU as a first-line treatment. MATERIALS AND METHODS: Data from nine French referral centers on patients treated with sRP between 2005 and 2017 were collected. Pre- and post-operative data, including oncological and functional outcomes after first treatment and sRP, were analyzed to determine the predictors for biochemical recurrence (BCR) and cancer-specific survival (CSS) after sRP. RESULTS: First-line treatments were external beam-radiation therapy (EBRT) for 30 (55%), brachytherapy (BT) for 10 (18%), and high-intensity focused ultrasound (HIFU) for 15 (27%). Median (IQR) PSA at diagnosis was 6.4 (4.9-9.5) ng/mL, median PSA at nadir was 1.9 (0.7-3.0) ng/mL, and median (IQR) to first BCR was 13 (6-20) months. Of the 55 patients, 44 (80%) received robot-assisted salvage radical prostatectomy and 11 (20%) received salvage retropubic radical prostatectomy. Restoration of continence was achieved in 90% of preoperatively continent patients; 24% that had received nerve-sparing (NS) procedures were potent after surgery. Prolonged catheterization due to anastomotic leakage was the most common complication. Age, preoperative clinical stage, NS procedure, and a pathological Gleason score were predictors for BCR. CONCLUSIONS: sRP was safe, feasible, and effective using either an open or robot-assisted approach, in experienced hands. Age, preoperative clinical stage, NS procedure, and pathological GS were linked with BCR after sRP.

AMS-800 Artificial urinary sphincter in female patients with stress urinary incontinence: A systematic review.

AIMS: To perform a systematic review of studies reporting the outcomes of AMS-800 artificial urinary sphincter (AUS) implantation in female patients with stress urinary incontinence (SUI) resulting from intrinsic sphincter deficiency (ISD). METHODS: A systematic literature search of the Medline and Embase databases was performed in June 2018 in accordance with the PRISMA statement. No time limit was used. The protocol was registered in PROSPERO (CRD42018099612). Study selection and data extraction were performed by two independent reviewers. RESULTS: Of 886 records screened, 17 were included. All were retrospective or prospective non-comparative case series. One study reported on vaginal AUS implantation, 11 on open AUS implantation, two on laparoscopic AUS implantation, two on robot-assisted AUS implantation and one compared open and robot-assisted implantations. The vast majority of patients had undergone at least one anti-incontinence surgical procedure prior to AUS implantation (69.1-100%). The intraoperative bladder neck injury rates ranged from 0% to 43.8% and the intraoperative vaginal injury rates ranged from 0 to 25%. After mean follow-up periods ranging from 5 to 204 months, the complete continence rates ranged from 61.1% to 100%. The rates of explantation, erosion and mechanical failure varied from 0% to 45.3%, 0% to 22.2% and 0% to 44.1%, respectively. CONCLUSIONS: AMS-800 AUS can provide excellent functional outcomes in female patients with SUI resulting from ISD but at the cost of a relatively high morbidity. High level of evidence studies are needed to help better define the role of AUS in the female SUI armamentarium.

Updated Systematic Review and Meta-analysis of the Comparative Data on Colposuspensions, Pubovaginal Slings, and Midurethral Tapes in the Surgical Treatment of Female Stress Urinary Incontinence.

CONTEXT: Retropubic (RP-TVT) and transobturator miurethral (TO-TVT) midurethral sling (MUS) are popular surgical treatments for female stress urinary incontinence. The long-term efficacy and safety of the procedures is still a topic of intense clinical research and several randomised controlled trials (RCTs) have been published in the last years OBJECTIVE: To evaluate the efficacy and safety of MUS compared with other surgical treatments for female stress urinary incontinence. EVIDENCE ACQUISITION: A systematic review and meta-analysis of the literature was performed using the Medline, Scopus, and Web of Science databases to update our previously published analyses. EVIDENCE SYNTHESIS: Twenty-eight RCTs were identified. In total, the meta-analyses included 15 855 patients. Patients receiving MUS had significantly higher overall (odds ratio [OR]: 0.59, p=0.0003) and objective (OR: 0.51, p=0.001) cure rates than those receiving Burch colposuspension. Patients undergoing MUS and pubovaginal slings had similar cure rates. Patients treated with RT-TVT had higher subjective (OR: 0.83, p=0.03) and objective (OR: 0.82, p=0.01) cure rates than those receiving TO-TVT. However, the latter had a lower risk of intraoperative bladder or vaginal perforation (OR: 2.4, p=0.0002), pelvic haematoma (OR: 2.61, p=0.002), urinary tract infections (OR: 1.31, p=0.04) and voiding lower urinary tract symptoms (OR: 1.66, p=0.002). Sensitivity analyses limited to RCTs with follow-up durations >60 mo demonstrated similar outcomes for RP-TVT and TO-TVT. No significant differences in efficacy were identified comparing inside-to-out and outside-to-in TO-TVT but vaginal perforations were less common with the former (OR: 0.21, p=0.0002). CONCLUSIONS: The present analysis confirms the superiority of MUS over Burch colposuspension. The studies comparing insertion of RT-TVT and TO-TVT showed higher subjective and objective cure rates for the RP-TVT but at the cost of higher risks of some complications and voiding lower urinary tract symptoms. Efficacy of inside-out and outside-in techniques of TO-TVT insertion was similar, although the risk of vaginal perforation was lower in the inside-to-out TO-TVT. PATIENT SUMMARY: Retropubic and transobturator midurethral slings are a popular treatment for female stress urinary incontinence. The available literature suggest that those slings are either more effective or safer than other older surgical procedures. Retropubic tapes are followed with slightly higher continence rates as compared with the transobturator tapes but are associated with higher risk of intra- and postoperative complications.

Outcomes Following First-line Endourologic Management of Ureteroenteric Anastomotic Strictures After Urinary Diversion: A Single-center Study.

OBJECTIVE: To assess the outcomes of patients following a first-line systematic endourologic procedure used to treat ureteroenteric anastomotic strictures (UEAS). MATERIALS AND METHODS: All data from patients treated using a first-line endourologic approach for UEAS between 2010 and 2015 were reviewed retrospectively. The following data were analyzed: age, type of urinary diversion, initial symptoms, surgical endoscopic approach (antegrade or retrograde), pre- and postoperative creatinine levels, and postoperative complications and outcomes. Follow-up visits occurred at 6 weeks, 3 months, and 6 months postoperatively, and at least annually thereafter. RESULTS: A total of 27 patients (median age: 62.5 years) were included. Overall, 28 UEAS were treated endoscopically (ileal conduit: n = 25; neobladder: n = 3). Most UEAS developed following radical cystectomy for bladder cancer (n = 19). Overall, the endoscopic approach was successful in 20 cases (71.4%). The UEAS length was >1 cm in 21 cases (75%). All UEAS of <1 cm were treated successfully (n = 7). There were three grade II and five grade III complications. The median follow-up period was 25 months. The median creatinine levels before surgery and at last follow-up were 1.3 mg/dL and 0.9 mg/dL, respectively. CONCLUSION: An endourologic procedure is a reasonable option for first-line treatment for UEAS and has promising functional outcomes and limited morbidity.

18F-FPRGD2 PET/CT imaging of integrin αvß3 in renal carcinomas: correlation with histopathology.

UNLABELLED: This study aimed to correlate (18)F-FB-mini-PEG-E[c(RGDyK)](2) ((18)F-FPRGD2) uptake to integrin αvß3 expression and angiogenesis in renal tumors. METHODS: (18)F-FPRGD2 PET/CT was performed on 27 patients before surgical resection (median 4 d) of a renal mass. The (18)F-FPRGD2 uptake was compared with integrin αvß3, CD31, CD105, and Ki-67 using immunohistochemistry; with placental growth factor and vascular endothelial growth factor receptors 1 and 2 using reverse transcription polymerase chain reaction; and with vascular endothelial growth factor A isoforms using enzyme-linked immunosorbent assay. RESULTS: Overall, (18)F-FPRGD2 uptake significantly correlated (P < 0.0001) with integrin αvß3 expression in renal masses. However, it correlated only with integrin αvß3-positive vessels in the group of papillary carcinomas whereas it correlated with integrin αvß3 expression by tumor cells in the clear cell carcinoma group. CONCLUSION: (18)F-FPRGD2 uptake reflects the expression of integrin αvß3 in renal tumors but represents angiogenesis only when tumor cells do not express the integrin.

[Epidemiology of urolithiasis in Belgium on the basis of a morpho-constitutional classification]. / Épidémiologie de la lithiase urinaire en Belgique sur base d'une classification morpho-constitutionnelle.

Urolithiasis is a common condition, with a prevalence of ∼10% and a male/female ratio above 1 according to large national series. Various types of urinary stones have been described upon their mineral content and/or their morphology. Hence, a combined morpho-constitutional (M-C) classification has been proposed. In order to detail the prevalence of urolithiasis in general and of each M-C type in particular upon age and gender in Belgium, we retrospectively studied the database of a reference center for urolithiasis analysis. Between 2010 and 2013, 2195 stones were characterized. We excluded 45 non-biological stones and 281 stones, which originated from outside the study zone. Among 1869 stones, 1293 (69.2%) affected men. Prevalence peak of urolithiasis was observed between 50-60 years of age in both genders. The M-C analysis was available for 1854 stones (99.2%): multiple morphological types were concomitantly identified in 49.3%. In the whole population, the main mineral constituent was whewellite (54.4%), mainly organized as type Ia (94%). Weddellite was found in 19.8%, with an equal distribution between types IIa and IIb. Uric acid was the 3rd most frequent constituent in man, with a similar distribution between IIIa and IIIb. Phosphate was uncommon in man (8.2%), but frequent in woman (26.6%) with a type IVa1 organization. Prevalence of M-C types changes with aging, i.e. decrease of weddellite and increase of whewellite and uric acid in both genders. This retrospective analysis of a single-center database of urinary stones helps characterize the M-C epidemiology of urolithiasis in Belgium.

A review of the current status of laparoscopic and robot-assisted sacrocolpopexy for pelvic organ prolapse.

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 124 min (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 202 min (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.

Incidence and risk factors of postoperative stress urinary incontinence following laparoscopic sacrocolpopexy in patients with negative preoperative prolapse reduction stress testing.

INTRODUCTION AND HYPOTHESIS: The objectives of this study were to evaluate the incidence of postoperative stress urinary incontinence (SUI) after laparoscopic sacrocolpopexy (LSCP) in women with negative preoperative prolapse reduction 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 analysis. 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 prolapse (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 analyses identified preoperative SUI as the sole independent predictor of subjective SUI [risk ratio (RR = 4.03; 95% confidence interval (CI) = 1.16-14.09), objective SUI, (RR = 4.67; 95% CI = 1.14-19.23), and subsequent anti-SUI surgery after LSCP (RR = 6.17; 95% CI = 1.30-29.41). 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.

New surgical technique for treatment of stress urinary incontinence TVT-ABBREVO from development to clinical experience.

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.
