Anterior approach sacrospinous hysteropexy: native tissue compared with mesh-augmented repair for primary uterovaginal prolapse management.

INTRODUCTION AND HYPOTHESIS: Anterior sacrospinous hysteropexy (SSH) was popularized by transvaginal mesh kits. Following mesh-kit market withdrawal, we hypothesized similar efficacy through native-tissue reattachment of the pubocervical fascia with fixation of the anterior cervix to the sacrospinous ligament. Few analyses for anterior native-tissue versus mesh-augmented SSH exist. METHODS: A retrospective analysis of women who underwent transvaginal anterior SSH between 01 January 2016 and 31 December 2022 was performed. Women who underwent a mesh-augmented (Uphold Lite Vaginal Support System™) versus native-tissue repair were compared. Composite success was defined as no bulge symptoms, no retreatment, and no recurrence beyond the hymen with apex nondescended > one third of the total vaginal length. Descriptive and bivariate statistics were obtained as indicated. RESULTS: Of 223 women screened, inclusion criteria were met by 124 (40 mesh-augmented; 84 native-tissue). There was no difference in pre-operative characteristics between groups. Composite success was demonstrated in 95.2% of women with a median follow-up of 224 days (range: 30-988). Two women in the mesh-augmented group reported bulge symptoms and underwent re-treatment with a pessary. Four women in the native-tissue group reported bulge symptoms; 3 underwent re-treatment (2 pessary, 1 surgery). There were no differences in composite success rates between groups (p=0.954). There were additionally no differences in intra-operative (p=0.752) or post-operative (p=0.292) complication rates between the groups. There were no mesh-related complications, including exposure or chronic pelvic pain. CONCLUSIONS: Ninety-five percent of women achieved surgical success and the use of mesh augmentation did not confer added benefit in terms of efficacy or complications when compared with native tissue. Further long-term data are needed to continue our assessment of native-tissue anterior SSH.

The importance of extranodal extension in penile cancer: a meta-analysis.

BACKGROUND: The role of extranodal extension (ENE) in penile cancer is controversial and has not been well studied. The aim of this study was to investigate the importance of ENE in predicting prognosis and presence of pelvic lymph node metastasis (PLNM) in penile cancer patients. METHODS: We searched related studies in Medline, Embase, Cochrane Library, and Scopus database. Hazard ratio (HR) and odds ratio (OR) were directly extracted or indirectly estimated from the included studies. RESULTS: A total of ten studies with 1,142 patients were included in this meta-analysis. Patients with ENE showed a worse cancer-specific survival (CSS) (HR = 1.90, 95 % confidence interval [CI] = 1.35-2.67, P = 0.0002) and overall survival (HR = 4.04, 95 % CI = 1.02-16.1, P = 0.05) than those without ENE. Further subgroup analysis revealed that the predictive value of ENE for CSS in penile cancer patients was significant regardless of the study's country of origin, but not in the subgroup with shorter follow-up time (<36 months, P = 0.38). Patients with ENE also showed a higher incidence of presenting with PLNM (OR = 4.95, 95 % CI = 2.58-9.49, P < 0.001). A stratified analysis demonstrated that the predictive role of ENE for PLNM was only detected in studies with a larger sample size (> 100 cases). No significant publication bias was observed, as suggested by Begg's and Egger's tests. CONCLUSIONS: ENE is associated with worse prognosis and high risk of PLNM in penile cancer patients. Due to the limited number of studies included in this meta-analysis, a large-scale, well-designed study will be required to verify our results.

Patient Satisfaction, Provider Productivity, and Efficacy of a Standardized Preparatory Toolkit With Broad Telemedicine Adaptation in an Outpatient Urology Clinic.

IMPORTANCE: The COVID-19 pandemic prompted telemedicine adoption. In March 2020, we developed an implementation toolkit with a nursing protocol for patient preparation before tertiary care urology clinic visits. OBJECTIVES: Our primary objective was to determine patient satisfaction after implementation of a telemedicine toolkit. Our secondary objective was to assess downstream productivity generated from telehealth visits. STUDY DESIGN: We prospectively conducted a postvisit survey that included the Telehealth Usability Questionnaire, a validated survey assessing patient satisfaction, for all patients with documented completion of the nursing protocol to assess patient experience and satisfaction. We then performed a retrospective chart review of all telemedicine visits to determine downstream outcomes, including imaging and procedure scheduling. RESULTS: Between April and May 2020, 1,422 visits were completed, of which 265 had complete nursing protocol documentation. Eighteen of 265 (6.8%) reported setup assistance. Four (1.8%) were unsuccessful and converted to a nonvisual phone visit. Overall, 186 (70.1%) completed the Telehealth Usability Questionnaire with a mean score of 118.31 ± 23.44. High satisfaction was reported regardless of race, marital status, income, education, employment status, or travel distance. Younger age ( P = 0.017) and female sex ( P = 0.017) were associated with greater satisfaction. Of 1,422 total visits, imaging was ordered in 29%, office procedures scheduled in 14%, and surgery scheduled in 14%. New visits were more likely to result in procedure and surgery scheduling than returns ( P < 0.0001). CONCLUSIONS: Our telemedicine toolkit designed to maximize patient engagement was successful in achieving patient-provider connectivity in 98% of patients with high satisfaction. Telemedicine visits are effective to provide comprehensive urologic care with implications beyond the pandemic.

The Difference in Prognosis between Renal Sinus Fat and Perinephric Fat Invasion for pT3a Renal Cell Carcinoma: A Meta-Analysis.

BACKGROUND: In the current Tumour-Node-Metastasis (TNM) classification system for renal cell carcinoma (RCC), both renal sinus fat invasion (SFI) and perinephric fat invasion (PFI) are defined as T3a, suggesting that the prognosis should be similar for the two pathologic findings. Several studies, however, have reported a worse prognosis for SFI in patients with a T3a tumor. In order to compare the prognosis of these two pathologic findings (SFI versus. PFI) in a more comprehensive way, this meta-analysis was performed. METHODS: To identify relevant studies, Medline, Embase, Cochrane Library, and Scopus database were searched from the inception until October 2014. A meta-analysis was performed using Review Manager 5.2 and STATA 11. Pooled Odds ratio (OR) and/or hazard ratio (HR) with 95% confidence interval (CI) were calculated to examine the risk or hazard association. RESULTS: A total of 6 studies including 1031 patients qualified for analysis. T3a RCC patients with SFI were significantly associated with poor cancer specific survival(CSS) (HR: 1.47, 95% CI: 1.19-1.83; P<0.001) compared to those with PFI. In T3aNx/N0M0 subgroup, SFI patients also showed a worse prognosis than those with PFI (CSS, HR: 1.94, 95% CI: 1.21-3.12; P = 0.006). T3a RCC patients with SFI had higher Furhman grade, greater possibility of lymph node metastasis, sarcomatoid differentiation and tumour necrosis. Main limitation is the relatively small number of included studies. CONCLUSION: The present meta-analysis suggested that SFI is associated with worse CSS in patients with pT3a RCC. However, due to the small number of included studies, future studies with a large sample size are required to further verify our findings.

Mapping and morphometric analysis of synapses and spines on fusiform cells in the dorsal cochlear nucleus.

Fusiform cells are the main integrative units of the mammalian dorsal cochlear nucleus (DCN), collecting and processing inputs from auditory and other sources before transmitting information to higher levels of the auditory system. Despite much previous work describing these cells and the sources and pharmacological identity of their synaptic inputs, information on the three-dimensional organization and utltrastructure of synapses on these cells is currently very limited. This information is essential since an understanding of synaptic plasticity and remodeling and pathologies underlying disease states and hearing disorders must begin with knowledge of the normal characteristics of synapses on these cells, particularly those features that determine the strength of their influence on the various compartments of the cell. Here, we employed serial block face scanning electron microscopy (SBFSEM) followed by 3D reconstructions to map and quantitatively characterize synaptic features on DCN fusiform cells. Our results reveal a relative sparseness of synapses on the somata of fusiform cells but a dense distribution of synapses on apical and basal dendrites. Synapses on apical dendrites were smaller and more numerous than on basal dendrites. The vast majority of axosomatic terminals were found to be linked to other terminals connected by the same axon or different branches of the same axon, suggesting a high degree of divergent input to fusiform cells. The size of terminals was correlated with the number of mitochondria and with the number of active zones, which was highly correlated with the number of postsynaptic densities, suggesting that larger terminals exert more powerful influence on the cell than smaller terminals. These size differences suggest that the input to basal dendrites, most likely those from the auditory nerve, provide the most powerful sources of input to fusiform cells, while those to apical dendrites (e.g., parallel fiber) are weaker but more numerous.
