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 ▲]

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 ▲]

CONTEXT: Burch colposuspension, pubovaginal sling, and midurethral retropubic tape (RT) and transobturator tape (TOT) have been the most popular surgical treatments for female stress urinary incontinence (SUI). Several randomized controlled trials (RCTs) have been published comparing the different techniques, with conflicting results. OBJECTIVE: Our aim was to evaluate the efficacy, complication, and reoperation rates of midurethral tapes compared with other surgical treatments for female SUI. EVIDENCE ACQUISITION: A systematic review of the literature was performed using the Medline, Embase, Scopus, Web of Science databases, and Cochrane Database of Systematic Reviews. EVIDENCE SYNTHESIS: Thirty-nine RCTs were identified. Patients receiving midurethral tapes had significantly higher overall (odds ratio [OR]: 0.61; confidence interval [CI]: 0.46-0.82; p=0.00009) and objective (OR: 0.38; CI: 0.25-0.57; p<0.0001) cure rates than those receiving Burch colposuspension, although they had a higher risk of bladder perforations (OR: 4.94; CI: 2.09-11.68; p=0.00003). Patients undergoing midurethral tapes and pubovaginal slings had similar cure rates, although the latter were slightly more likely to experience storage lower urinary tract symptoms (LUTS) (OR: 0.31; CI: 0.10-0.94; p=0.04) and had a higher reoperation rate (OR: 0.31; CI: 0.12-0.82; p=0.02). Patients treated with RT had slightly higher objective cure rates (OR: 0.8;CI: 0.65-0.99; p=0.04) than those treated with TOT; however, subjective cure rates were similar, and patients treated with TOT had a much lower risk of bladder and vaginal perforations (OR: 2.5; CI: 1.75-3.57; p<0.00001), hematoma (OR: 2.62; CI: 1.35-5.08; p=0.005), and storage LUTS (OR: 1.35; CI: 1.05-1.72; p=0.02). Meta-analysis demonstrated similar outcomes for TVT-O (University of Liege, Liege, Wallonia, Belgium) and Monarc (AMS, Minnetonka, MN, USA). CONCLUSIONS: Patients treated with RT experienced slightly higher continence rates than those treated with Burch colposuspension, but they faced a much higher risk of intraoperative complications. RT and pubovaginal slings were similarly effective, although patients with pubovaginal slings were more likely to experience storage LUTS. The use of RT was followed by objective cure rates slightly higher than TOT, but subjective cure rates were similar. TOT had a lower risk of bladder and vaginal perforations and storage LUTS than RT. The strength of these findings is limited by the heterogeneity of the outcome measures and the short length of follow-up. [less ▲]

BACKGROUND: Accumulating evidence suggests that DNA methylation markers could serve as sensitive and specific cancer biomarkers. OBJECTIVE: To determine whether a panel of methylated genes would have the potential to identify primary bladder cancer (BCa) in voided urine samples. DESIGN, SETTING, AND PARTICIPANTS: A pharmacologic unmasking reexpression analysis in BCa cell lines was initially undertaken to unveil candidate methylated genes, which were then evaluated in methylation-specific polymerase chain reaction (MSP) assays performed on DNA extracted from noncancerous and cancerous bladder tissues. The most frequently methylated genes in cancerous tissues, with 100% specificity, were retained for subsequent MSP analysis in DNA extracted from urine samples to build and validate a panel of potential methylated gene markers. Urine samples were prospectively collected at three urologic centres from patients with histologically proven BCa and processed for use in real-time MSP and cytologic analysis. Patients with nonmalignant urologic disorders were included as controls. MEASUREMENTS: A urine sample was classified as valid when >/=10 copies of the gene encoding ss-actin were measured in the urine sediment genomic DNA. Sensitivity, specificity, and predictive values of the MSP and cytology tests were assessed and compared. RESULTS AND LIMITATIONS: MSP assays performed on 466 of the 496 (94%) valid urine samples identified two genes, TWIST1 and NID2, that were frequently methylated in urine samples collected from BCa patients, including those with early-stage and low-grade disease. The sensitivity of this two-gene panel (90%) was significantly better than that of cytology (48%), with comparable specificity (93% and 96%, respectively). The positive predictive value and negative predictive value of the two-gene panel was 86% and 95%, respectively. CONCLUSIONS: Detection of the methylated TWIST1 and NID2 genes in urine sediments using MSP provides a highly (>/=90%) sensitive and specific, noninvasive approach for detecting primary BCa.

OBJECTIVES: Medium-term results of transobturator tapes for the treatment of female stress urinary incontinence (SUI) are largely unknown. We analyzed the 3-yr results of a prospective, observational study designed to evaluate the safety and efficacy of the TVT-O procedure. METHODS: Preoperative and postoperative evaluations included physical examination, uroflowmetry and postvoid residual (PVR) measurement, and urinary symptoms and quality of life (QoL) questionnaires. Data were compared by means of the Wilcoxon matched pairs test. RESULTS: Between March 2003 and December 2003, 102 consecutive patients with clinical and urodynamic diagnoses of SUI who fulfilled inclusion and exclusion criteria underwent the TVT-O procedure; the latter was associated with pelvic organ prolapse treatment in 16 patients (15.7%). Three-year minimum follow-up (median, 40 mo) was available for 91 patients (89.2%). No erosion or persistent pain was noted. Four patients required tape release or section. Disappearance and improvement of SUI were observed in 88.4% and 9.3% of the patients, respectively. These cure rates were similar to those obtained 1 yr after the operation (p=0.55). Frequency and urge symptoms were improved at 3 yr (p<0.005). Whereas maximum flow rates were somewhat decreased (p=0.01), the severity of obstructive symptoms and PVR volumes were not statistically different (p=0.11 and p=0.32, respectively). Incontinence severity and QoL scale scores were largely better than preoperative ones (p<0.001) and did not differ from those reported at 1 yr (p=0.15 and p=0.08, respectively). CONCLUSIONS: The TVT-O procedure is a safe and efficient treatment of female SUI, with maintenance of high cure rates after a 3-yr minimum follow-up. [less ▲]

OBJECTIVES: To describe a new sling procedure for treating stress urinary incontinence (SUI) after radical prostatectomy (RP) and prospectively evaluate its short-term safety and efficacy. METHODS: The sling technique uses specific instruments and a polypropylene mesh with two arms that are passed inside to outside through the obturator foramens, pulled for compressing the bulbar urethra upward, and tied to each other across the midline. Patients with detrusor overactivity were excluded. Baseline and follow-up evaluations included uroflowmetry and continence and quality of life (QoL) questionnaires. Cure was defined by no pad use and improvement by a number of pads/d <or=2 and reduced by at least 50%. Complications were recorded. RESULTS: From April 2006 through February 2007, 20 consecutive patients suffering from post-RP SUI underwent the sling procedure using the same operative protocol. Preoperatively, 3 (15%), 11 (55%), and 6 (25%) patients were using 2, 3-5, and >5pads/d, respectively. The procedure was preceded by an endoscopic urethrotomy in four patients. No perioperative complication was noted; three patients required suprapubic catheterization. At 6 mo, nine (45%) patients were cured and eight others (40%) were improved (1pad/d). QoL was significantly enhanced and 80% of patients were moderately to completely satisfied with the procedure. Preoperative and postoperative maximum flow rate and postvoid residual values were not statistically different. No sling infection, urethra erosion, persistent pain, or neurologic complications were observed. CONCLUSIONS: The inside-out trans-obturator sling procedure appears to be safe and efficient at short term. Further studies are warranted to determine long-term outcome. [less ▲]

OBJECTIVE: We investigated the potential involvement of the thromboxane A(2) (TXA(2)) pathway in human prostate cancer (PCa). METHODS: Expression of cyclooxygenase-2 (COX-2), TXA(2) synthase (TXS), and TXA(2) receptors (TPRs), the main actors of the TXA(2) pathway, was analyzed on serial tissue sections from 46 human PCa specimens. RESULTS: The expression levels of COX-2, TXS, and TPRs were significantly higher in malignant than in corresponding nontumoral prostatic epithelial cells. Increased immunoreactivity for these antigens was also observed in high-grade prostate intraepithelial neoplasia (HGPIN) glands. COX-2, TXS, and TPR proteins usually displayed a coordinated overexpression pattern in PCa lesions, as assessed in serial tissue sections. Increased levels of these proteins in the tumors were all significantly associated with higher Gleason scores and pathologic stages. CONCLUSIONS: Proteins specifically involved in the TXA(2) pathway are up-regulated in human PCa and their level of expression is associated with tumor extraprostatic extension and loss of differentiation. Our study is the first to examine simultaneously all key proteins involved in this pathway including TXA(2) receptors and results suggest that the TXA(2) pathway may be a potential target for PCa prevention/therapy.

OBJECTIVES: To describe a new, simple surgical technique for the treatment of female stress urinary incontinence (SUI) and to evaluate its feasibility. METHODS: We have developed a novel surgical treatment of SUI, the transobturator inside-out tension-free urethral suspension, which uses specifically designed surgical tools, and in which a synthetic tape is passed from underneath the urethra, through the obturator foramens, towards the thigh folds, without entering the pelvic region at any time during the procedure. The tape is positioned without tension under the junction between mid and distal urethra. RESULTS: The procedure was carried out in 107 consecutive patients (mean age: 62 years) using the same operative protocol in all case subjects, independently of the patient's size and weight. Mean operative time was 14 min (range: 7-20) in case of isolated SUI treatment. No bladder or urethral injuries and no vascular (hematoma or bleeding) or neurological complications were encountered. CONCLUSIONS: The results of this study indicate that our novel transobturator inside-out surgical technique for treating SUI is feasible, accurate, and quick. This technique avoids damage to the urethra and bladder and, therefore, makes cystoscopy not necessary. Further prospective studies are currently ongoing to determine the efficacy of our new surgical approach for treating SUI. [less ▲]

OBJECTIVES: Reliable prognostic indicators are needed for a better pretherapeutic assessment of the agressiveness of organ-confined prostate cancer (PC) lesions. The 67-kD laminin receptor (67LR) is a cell-surface-associated protein involved in the acquisition of the invasive and metastatic phenotype of a variety of human cancer cell types. We have previously shown that 67LR detection in PC tissues from radical prostatectomy (RP) specimens is an independent predictor of biochemical (PSA) relapse in patients with clinically localized PC. In this study, we assessed 67LR detection in diagnostic PC biopsies as a predictor of biochemical relapse after RP. METHODS: Diagnostic biopsy and subsequent RP tissue specimens from 151 patients with clinically localized PC were immunohistochemically analyzed for 67LR expression. The level of 67LR expression was evaluated by both intensity and extent of the staining. Clinicopathological preoperative and postoperative parameters, including 67LR expression, were correlated with each other and tested as predictors of biochemical relapse. RESULTS: 67LR was detected in 67.5 and 68.2% of biopsies and RPs, respectively. 67LR detection in RP specimens was an independent predictor of relapse. The level of 67LR expression in the biopsy was significantly associated with the biopsy Gleason score (p<0.05) but failed to predict the pathological stage (p>0.1). Biochemical progression-free estimates for patients whose biopsy did or did not express the protein differed with only borderline statistical significance (p = 0.05). Multivariate analysis identified biopsy Gleason score as the only independent preoperative predictor of recurrence. Significant discrepancies in levels of 67LR expression were found between matched biopsy and RP specimens (p<0.05), with exact agreement rates <40%. CONCLUSIONS: 67LR detection in PC biopsies was not a significant preoperative predictor of outcome after RP. Heterogeneity of 67LR expression and biopsy sampling errors most likely represented the main reasons for discordant results between biopsy and RP specimens. [less ▲]

Extracorporeal shockwave lithotripsy (ESWL) has been initially designed for stones located in the kidney and the upper ureter. Our lithotripter is no exception. Its components (the table and the orientation of the semi-ellipsoid reflector) are adapted for the treatment of kidney or lumbar ureter stones. However, the elements forming the unit of treatment (the table, the C-arm and the Tripter) can be modified in such a way that focalization of stones of the lower ureter becomes possible through a perineal exposure. The aim is to avoid the pelvic bone shield while a good focalization of the stone is realized. From June 1989 to March 1991, 35 patients were treated for distal ureteric stones by ESWL in this original positioning. [less ▲]
