Single-port robot-assisted simple prostatectomy: techniques and outcomes
No full textPurposeTo describe the surgical techniques and to analyse the outcomes of single-port robot-assisted simple prostatectomy (SP RASP) procedure for the surgical treatment of benign prostatic hyperplasia (BPH).MethodsThree databases (PubMed (R), Web of Science (TM), and Scopus (R)) were queried to identify studies reporting on the technical aspects and outcomes of SP RASP. Different combinations of keywords were used, according to a free-text protocol, to identify retrospective and prospective studies, both comparative and non-comparative, systematic reviews (SR) and meta-analysis (MA) describing surgical techniques for SP RASP and the associated surgical and functional outcomes.ResultsThe transvesical approach represents the most common approach for SP RASP. A decrease in terms of estimated blood loss was observed when SP RASP was compared to open simple prostatectomy (OSP) and multi-port (MP) RASP. Furthermore, this technique allowed for a shorter length of hospital stay (LoS) and a lower post-operative complication rate, compared to OSP. Post-operative subjective and objective functional outcomes are satisfying and comparable to OSP and MP RASP.ConclusionSP RASP represents a safe and feasible approach for the surgical management of BPH. It provides comparable surgical and functional outcomes to MP RASP, enabling for minimal invasiveness, enhanced recovery, and potential for improving patient care
Incidence and management of BPH surgery-related urethral stricture: results from a large U.S. database
Get PDFIntroduction and objectives: Urethral stricture (US) is a well-known complication after surgical treatment of benign prostatic hyperplasia (BPH). This study aimed to evaluate the contemporary incidence of the US after different types of BPH surgery, to identify associated risk factors and to assess its management. Methods: A retrospective analysis was conducted using the PearlDiver (TM) Mariner database, containing de-identified patient records compiled between 2011 and 2022. Specific International Classification of Diseases (ICD) and Current Procedural Terminology (CPT) codes were employed to identify population characteristics and outcomes. All the most employed surgical procedures for BPH treatment were considered. Multivariable logistic regression was employed to evaluate factors associated with diagnosis of post-operative US. Results: Among 274,808 patients who underwent BPH surgery, 10,918 developed post-operative US (3.97%) within 12 months. Higher incidence of US was observed following TURP (4.48%), Transurethral Incision of the Prostate (TUIP) (3.67%), Photoselective Vaporization of the Prostate (PVP) (3.92%), HoLEP/ThuLEP (3.85%), and open Simple Prostatectomy (SP) (3.21%). Lower incidence rates were observed after laparoscopic\robot-assisted SP (1.76%), Aquablation (1.59%), Prostatic Urethral Lift (PUL) (1.07%), Rezum (1.05%), and Prostatic Artery Embolization (PAE) (0.65%). Multivariable analysis showed that patients undergoing PUL, Rezum, Aquablation, PAE, and PVP were associated with a reduced likelihood of developing US compared to TURP. US required surgical treatment in 18.95% of patients, with direct visual internal urethrotomy (DVIU) and urethroplasty performed in 14.55% and 4.50% of cases, respectively. Urethral dilatation (UD) in an outpatient setting was the primary management in most cases (76.7%). Conclusions: The present analysis from a contemporary large dataset suggests that the incidence of US after BPH surgery is relatively low (<5%) and varies among procedures. Around 94% of US cases following BPH surgery are managed using minimally invasive treatment approaches such as UD and DVIU
Prostate Cancer in Transgender Women: Epidemiology, Clinical Characteristics, and Management Challenges
No full textPurpose of ReviewTo systematically review the evidence on prostate cancer (PCa) in transgender women (TGW).Recent FindingsA total of 25 studies were included. Fourteen articles were case reports or case series describing 21 TGW with PCa; 11 papers focused primarily on assessing the incidence or screening of PCa in TGW. The median (range) age of patients with PCa was 63 (45-78) years. Median (range) PSA at diagnosis was 7.5 (0.4-1710) ng/mL. Prostate biopsy detected ISUP 3-5 in 10 (67%) cases. T3-4 stages were described in 7 (64%) patients. Three (14.3%) cases of nodal involvement and 2 (9.5%) of metastases were reported at diagnosis. First-line therapy included radical prostatectomy or radiotherapy +/- androgen deprivation therapy in 14 (74 %) subjects. Median (range) follow-up was 24 (2-120) months. A good response to first-line therapy was recorded in 8 (47.1%) cases. Median (range) incidence of PCa in TGW was 44.1 (4.34-140) cases per 100,000 person-years. PCa was significantly less frequent in TGW than in cisgender males (HR 0.4, 95% CI 0.2-0.9). Risk of death after PCa diagnosis was significantly higher in TGW compared to cisgender males (HR 1.91, 95% CI 1.06-3.45). TGW had lower lifetime PSA rates (48% vs. 64.6%, p = 0.048) than cisgender males.SummaryFew cases of PCa in TGW are currently reported. PCa seems significantly less frequent in TGW than in cisgender males; however, some data suggest a possible higher mortality in this cohort. TGW appear to have less access to PSA testing than cisgender men
Characteristics, trends, and management of Penile cancer in the United States: A population-based study
No full textBackground: Penile cancer (PeCa) is a rare disease. HPV infection, smoking, phimosis, and lichen sclerosus represent well-known associated risk factors. Objectives: Primary aim of our study is to evaluate the incidence and risk factors of PeCa and to outline the adopted diagnostic and therapeutic approaches. Secondary aim is to investigate risk factors associated with aggressive disease and to identify the complications arising from its surgical treatment. Materials and Methods: We conducted a retrospective analysis using the PearlDiverTM Mariner database, from January 1, 2011, to December 31, 2021, identifying all patients diagnosed with PeCa and PeIN, evaluating comorbidities, risk factors, and social and economic conditions. We evaluated the imaging modalities employed for staging as well as the treatment strategies. Finally, we evaluated the most frequent complications associated with inguinal lymphadenectomy (ILND). Results: During the study period, 17,494 patients were diagnosed with PeCa and 5,965 with penile intraepithelial neoplasia (PeIN). US was the most frequently utilized imaging modality, followed by PET and PET/CT. Use of CT and MRI was around 5%. Surgical treatment was the predominant strategy, utilized in 31.3% of PeCa and 22.9% of PeIN. Wide Local Excision/Glansectomy emerged as the most common surgical procedures. MLR analysis identified smoking as a risk factor for metastatic PeCa (OR; 95% CI = 1.49; 1.379-1.609), HPV infections were associated with a 35% decrease in risk (OR; 95% CI = 0.65; 0.562-0.744) (all P < 0.001). Lichen sclerosus and phimosis were associated with a doubled risk of demolitive surgery. Approximately 40% of patients experienced complications associated with ILND. Conclusion: Despite advances in PeCa management, there's no significant move toward more conservative treatments. Surgical treatments are still marked by high rates of complications, potentially affect the sexual and psychosocial health of patients. These issues may foster a tendency toward avoidance behaviors, contributing to a delayed clinical presentation and treatment. (c) 2024 Elsevier Inc.

Minimally Invasive Adrenalectomy: A Population-Based Analysis of Contemporary Trends, Outcomes, Costs, and Impact of Social Determinants of Health
No full textIntroduction: We sought to analyze temporal trends in the utilization of minimally invasive vs open adrenalectomy in the United States; to assess costs, perioperative outcomes, and the determining factors influencing these variables. Methods: A retrospective analysis of claims data obtained from PearlDiver Mariner, a Health Insurance Portability and Accountability Act-compliant deidentified nationwide database of insurance billing records, was performed. Per-population utilization rates and trends were analyzed using negative binomial regression and trends tests respectively. Continuous and categorical variables were compared using 2-sided t tests and chi 2 tests. Multivariable logistic regression analysis was conducted to identify predictors of perioperative complication. Results: A total of 10,753 patients were identified (mean age 53.3 +/- 16.1 years). Using the 2011 to 2014 time frame as reference, utilization of adrenalectomy decreased over time (incidence rate ratio for 2015-2018: 0.65 [95% CI 0.62-0.68, P < .001]; incidence rate ratio for 2019-2021: 0.39 [95% CI 0.37-0.41, P < .001]). Minimally invasive adrenalectomies increased significantly over time (P < .001). A greater number of adrenalectomies were performed by general surgeons compared with urologists (70.4% vs 29.5%). Complications were not significantly predicted by any surgical specialty. Significant predictors for complication rates were Charlson comorbidity index > 1 (odds ratio [OR] 1.11, 95% CI 1.09-1.13), presence of social determinants of health (OR 1.5, 95% CI 1.18-1.88) and open approach (OR 1.54, 95% CI 1.34-1.77). Conclusions: The number of adrenalectomies in the United States decreased over the past decade, with a shift towards minimally invasive approach. No difference in outcomes for general surgeons vs urologists can be observed. Social determinants of health are independent predictors of increased rate of complications

Single Port Robotic Pyeloplasty: early single-center experience
No full textPurpose: Ureteropelvic junction obstruction (UPJO) is a prevalent cause of hydronephrosis, especially in young patients. The treatment paradigm for this condition has shifted from open to minimally invasive pyeloplasty. In the present study we describe our initial single centre experience with single port (SP) robot-assisted pyeloplasty (RAP) via periumbilical incision. Material and methods: With the patient in a 60-degree left flank position, the SP system is docked with the Access port (Intuitive Surgical, Sunnyvale, CA, US) placed in a periumbilical 3 cm incision. Robotic instruments are deployed as follows: camera at 12 o'clock, bipolar grasper at 9 o'clock, scissors at 3 o'clock and Cadiere at 6 o'clock. After isolation and identification of the ureter and the ureteropelvic junction (UPJ), the ureter is transected at this level and then spatulated. Anastomosis is carried out by two hemicontinuous running sutures, over a JJ stent. Results: Between 2021 and 2023, a total of 8 SP RAP have been performed at our institution, with a median (interquartile range, IQR) of 23 years (20.5-36.5). Intraoperative outcomes showed a median (IQR) OT of 210.5 minutes (190-240.5) and a median (IQR) estimated blood loss (EBL) of 50 mL (22.5-50). No postoperative complications were encountered, with a median (IQR) length of stay (LOS) of 31 hours (28.5-34). Conclusion: In the present study we evaluated the feasibility and safety of SP RAP. The observed outcomes and potential benefits, combined with the adaptability of the SP platform, hold promising implications for the application of SP system in pyeloplasty treatment
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
