Incidence and management of BPH surgery-related urethral stricture: results from a large U.S. database.

INTRODUCTION 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™ 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.

Incidence and Management of Radiation Cystitis After Pelvic Radiotherapy for Prostate Cancer: Analysis from a National Database.

OBJECTIVES: To determine the incidence of radiation cystitis on Prostate Cancer (PCa) patients undergoing pelvic radiotherapy (RT), evaluating the most used management strategies, and identifying potential risk factors associated with the development of this condition. METHODS: A retrospective analysis was conducted using the PearlDiver™ Mariner database, containing patient records compiled between 2011 and 2022. International Classification of Diseases (ICD) and Current Procedural Terminology (CPT) codes were employed to identify population and outcomes. We evaluated patients who underwent RT for PCa and subsequently developed radiation cystitis. Primary objective was to determine the overall incidence of radiation cystitis. Furthermore, we investigated its associated risk factors and management. RESULTS: A total of 274,865 PCa patients underwent RT during the study period. Of these, 48,713 (17.7%) experienced hematuria following RT, while 7,721 (2.8%) were diagnosed with radiation cystitis. After the diagnosis, 2,307 patients (29.9%) received diagnostic or therapeutic endoscopic interventions. Only 59 patients (0.76%) underwent endovascular embolization, while 151 patients (1.95%) required cystectomy. Hyperbaric oxygen therapy, administered to 1,287 patients (16.67%), was the only treatment that displayed a significant upward trend. Multivariate logistic regression identified obesity (OR 1.29; 95% C.I. 1.23 - 1.35), smoking (OR 1.27; 95% C.I. 1.22 - 1.33), and diabetes (OR 1.32; 95% C.I. 1.26 - 1.39), as significant risk factors for radiation cystitis (all p-values < 0.001). CONCLUSIONS: Radiation cystitis represents a rare complication after pelvic RT with significant clinical impact. Its incidence has remained stable throughout the study period. The identified risk factors corroborate the pathophysiology of radiation cystitis. Hyperbaric oxygen therapy was the only treatment to show an upward trend during the study period.

Larval Frass of Hermetia illucens as Organic Fertilizer: Composition and Beneficial Effects on Different Crops.

Hermetia illucens has received a lot of attention as its larval stage can grow on organic substrates, even those that are decomposing. Black soldier fly breeding provides a variety of valuable products, including frass, a mixture of larval excrements, larval exuviae, and leftover feedstock, that can be used as a fertilizer in agriculture. Organic fertilizers, such as frass, bringing beneficial bacteria and organic materials into the soil, improves its health and fertility. This comprehensive review delves into a comparative analysis of frass derived from larvae fed on different substrates. The composition of micro- and macro-nutrients, pH levels, organic matter content, electrical conductivity, moisture levels, and the proportion of dry matter are under consideration. The effect of different feeding substrates on the presence of potentially beneficial bacteria for plant growth within the frass is also reported. A critical feature examined in this review is the post-application beneficial impacts of frass on crops, highlighting the agricultural benefits and drawbacks of introducing Hermetia illucens frass into cultivation operations. One notable feature of this review is the categorization of the crops studied into distinct groups, which is useful to simplify comparisons in future research.

Incidental Prostate Cancer in Patients Treated for Benign Prostatic Hyperplasia: Analysis from a Contemporary National Dataset.

(1) Background: Prostate Cancer (PCa) may be incidentally diagnosed during the microscopic evaluation of resected tissue from BPH surgeries, characterizing the clinical condition known as incidental PCa (iPCa). This study aims to assess the prevalence of iPCa following BPH surgery to evaluate the associated surgical procedures and to scrutinize preoperative and postoperative management. (2) Methods: A retrospective analysis was conducted using the PearlDiver™ Mariner database, containing patient records compiled between 2011 and 2021. International Classification of Diseases (ICD) and Current Procedural Terminology (CPT) codes were employed to identify the population and outcomes. Our primary objective was to assess the prevalence of iPCa, categorized by the type of procedures, and to evaluate the subsequent treatment strategies. The secondary aim was to assess the impact of prostate biopsy (PB) and prostate MRI on iPCa detection. (3) Results: The overall cohort, accounting for 231,626 patients who underwent BPH surgery, exhibited a 2.2% prevalence rate of iPCa. The highest rate was observed for TURP (2.32%), while the lowest was recorded for RASP (1.18%). Preoperative MRI and PB demonstrated opposing trends over the years. Of the 5090 patients identified with iPCa, nearly 68% did not receive active treatment. The most common treatments were RT and ADT; 34.6% underwent RT, 31.75% received ADT, and 21.75% were treated with RT+ADT. RP was administered to approximately 9% of patients undergoing endoscopic procedures. Multivariate logistic regression analysis revealed age and openSP as additional risk factors for iPCa. Conversely, PB and MRI before surgery were linked to a decreased risk. (4) Conclusions: The contemporary prevalence of iPCa after BPH surgery is <3%. The increase in the use of prostate MRI mirrors a decline in the PB biopsy prior to BPH surgery but without resulting in an increased detection rate of iPCa. In contemporary routine clinical practice, iPCa is mostly managed in a different way when compared to biopsy-detected PCa.

Trends and costs of minimally invasive surgery for kidney cancer in the US: A population-based study.

OBJECTIVE: To analyze temporal trends and costs associated with the use of minimally invasive surgery (MIS) for kidney cancer in the US over the past decade. To examine the impact of social determinants of health (SDOH) on perioperative outcomes. METHODS: The PearlDiver Mariner, a national database of insurance billing records, was queried for this retrospective observational cohort analysis. The MIS population was identified and stratified according to treatment modality, using International Classification of Diseases (ICD) and current procedural terminology (CPT) codes. SDOH were assessed using ICD codes. Negative binomial regression was used to evaluate the overall number of renal MIS and Cochran-Armitage tests to compare the utilization of different treatment modalities, over the study period. Multivariable logistic regression analysis identified predictors of perioperative complications. RESULTS: A total of 80,821 MIS for kidney cancer were included. Minimally invasive partial nephrectomy (MIPN) adoption as a fraction of total MIS increased significantly (slope of regression line, reg. = 0.026, p<.001). Minimally invasive radical nephrectomy (MIRN) ($26,9k±40,9k) and renal ablation (RA) ($18,9k±31,6k) were the most expensive and the cheapest procedure, respectively. No statistically significant difference was observed in terms of number of complications (p=.06) and presence of SDOH (p=.07) among the treatment groups. At multivariable analysis, patients with SDOH undergoing MIRN had higher odds of perioperative complications, while RA had a significantly lower probability of perioperative complications. CONCLUSIONS: This study describes the current management of kidney cancer in the US, offering a socioeconomic perspective on the impact of this disease in everyday clinical practice. DATA AVAILABILITY: Raw data generated during and/or analyzed during the current study are available from the corresponding author on reasonable request.

Benign Prostatic Hyperplasia Surgery: A Snapshot of Trends, Costs, and Surgical Retreatment Rates in the USA.

BACKGROUND: An increasing number of novel surgical treatments (NSTs) for benign prostatic hyperplasia (BPH) have been proposed over time to achieve similar functional outcomes, but better perioperative and sexual outcomes than traditional procedures. OBJECTIVE: To assess the trends in the utilization and costs of BPH surgical procedures over the past decade, and to analyze the need for surgical retreatment after each procedure. DESIGN, SETTING, AND PARTICIPANTS: A retrospective observational population-based analysis was conducted using the PearlDiver Mariner (PearlDiver Technologies, Colorado Springs, CO, USA) database, including all-payer nationally available claims records collected from 2011 to 2022. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The number and type of BPH surgical procedures per year, costs associated with each BPH surgical treatment, incidence of BPH surgical retreatment rate, and time to BPH surgical retreatment were assessed. Negative binomial regression and Cochran-Armitage test were used for the temporal trend analysis. A multivariable logistic regression analysis evaluated the predictors of BPH surgical retreatment. RESULTS AND LIMITATIONS: In the study period, 274 808 patients received surgical treatment for BPH. The most common procedure was transurethral resection of the prostate (TURP; 71.7%). The overall utilization of BPH surgical treatment increased over the study period. Traditional surgery remained most performed for the entire period (87.8%), but a statistically significantly rising trend of NSTs was recorded. The mean reimbursements paid per procedure was 1.43 times higher (p < 0.001) for NSTs than for traditional procedures. The surgical retreatment rate was 9.4%. The mean time to surgical retreatment was 25.3 mo, with 85.5% of cases re-treated within 5 yr. At the multivariable analysis, transurethral incision of the prostate, photoselective vaporization of the prostate, prostatic urethral lift, convective water vapor energy, and prostatic artery embolization had a significantly greater likelihood of surgical retreatment than TURP. Holmium/thulium laser enucleation of the prostate (HoLEP/ThuLEP), open simple prostatectomy (SP), and laparoscopic/robot-assisted SP were associated with a lower probability of resurgery than TURP, but a similar probability between these procedures. Retrospective design and a lack of relevant clinical data were the main limitations. CONCLUSIONS: Over the past decade, there has been a progressive increase in the adoption of NSTs. The rate of surgical retreatment appears <10%, with patients undergoing SP and HoLEP/ThuLEP experiencing a statistically significantly lower probability of surgical retreatment. PATIENT SUMMARY: We investigated the trends, costs, and surgical retreatments of benign prostatic hyperplasia surgery. Transurethral resection of the prostate remains the most common procedure. Novel surgical treatments are associated with an upward trend, despite appearing more expensive overall. Retreatment is necessary in <10% of patients and generally within 5 yr.

Trimodal therapy vs radical cystectomy in patients with muscle-invasive bladder cancer: a systematic review and meta-analysis of comparative studies.

OBJECTIVE: To perform a systematic review and meta-analysis of trials comparing trimodal therapy (TMT) and radical cystectomy (RC), evaluating differences in terms of oncological outcomes, quality of life, and costs. MATERIALS AND METHODS: In July 2023, a literature search of multiple databases was conducted to identify studies analysing patients with cT2-4 N any M0 muscle-invasive bladder cancer (MIBC; Patients) receiving TMT (Intervention) compared to RC (Comparison), to evaluate survival outcomes, recurrence rates, costs, and quality of life (Outcomes). The primary outcome was overall survival (OS). Secondary outcomes were cancer-specific survival (CSS) and metastasis-free survival (MFS). Hazard ratios (HRs) were used to analyse survival outcomes according to different treatment modalities and odds ratios were used to evaluate the likelihood of receiving each type of treatment according to T stage. RESULTS: No significant difference in terms of OS was observed between RC and TMT (HR 1.07, 95% confidence interval [CI] 0.81-1.4; P = 0.6), even when analysing radiation therapy regimens ≥60 Gy (HR 1.02, 95% CI 0.69-1.52; P = 0.9). No significant difference was observed in CSS (HR 1.12, 95% CI 0.79-1.57, P = 0.5) or MFS (HR 0.88, 95% CI 0.66-1.16; P = 0.3). The mean cost of TMT was significantly higher than that of RC ($289 142 vs $148 757; P < 0.001), with greater effectiveness in terms of cost per quality-adjusted life-year. TMT ensured significantly higher general quality-of-life scores. CONCLUSION: Trimodal therapy appeared to yield comparable oncological outcomes to RC concerning OS, CSS and MFS, while providing superior patient quality of life and cost effectiveness.

Post-Voided Residual Ratio Does Not Predict Trifecta Outcome after Transurethral Resection of Prostate.

The purpose of this study was to assess the importance of the post-void residual (PVR) ratio (PVR ratio) in achieving a favorable trifecta outcome for patients suffering from lower urinary tract symptoms and benign prostatic enlargement (LUTS-BPE) who undergo transurethral resection of the prostate (TURP). Starting from 2015, a series of patients with LUTS-BPE who underwent TURP were included in a forward-looking study. These patients were assessed using the international prostate symptom score (IPSS) screening tool, uroflowmetry, and a transrectal ultrasound to measure prostate volume (TRUS). Both the PVR urine volume and the PVR ratio (PVR-R), which is the PVR as a percentage of total bladder volume (voided volume + PVR), were measured. The assessment of outcomes was based on the trifecta favorable outcome, defined as meeting all of the following criteria: (1) absence of perioperative complications, (2) a postoperative IPSS of less than eight, and (3) a postoperative maximum urinary flow rate (Qmax) greater than 15 mL/s. A total of 143 patients were included, with a median age of 70 years (interquartile range 65-73). Of these, 58% (83/143) achieved a positive trifecta outcome. Upon conducting a multivariate analysis, both IPSS and Qmax were identified as predictors of a positive trifecta outcome, whereas the PVR-R did not prove to be an independent predictor. In summary, it was found that preoperative IPSS and Qmax are indicative of a trifecta outcome following TURP, whereas PVR-R is not.

Comparative Outcomes of Open Radical Cystectomy vs. Robot-Assisted Approaches with Intracorporeal and Extracorporeal Urinary Diversion: A Meta-Analysis and Network Meta-Analysis of Perioperative and Quality of Life Outcomes.

Background: To conduct a comprehensive systematic review and network meta-analysis of RCTs that compare outcomes of robot-assisted radical cystectomy (RARC) with intra- or extracorporeal urinary diversion (ICUD or ECUD) and the standard open approach (oRC). Methods: A systematic review identified RCTs including patients aged >18 years with non-metastatic bladder cancer treated with RARC (ICUD or ECUD) vs. oRC and reporting peri- and post-operative outcomes and quality of life (QoL) assessment. Standard and network metanalyses were performed. Results: Data from 1024 patients included in eight RCTs were analyzed. The standard meta-analysis found that RARC had longer OT, lower EBL, and a lower transfusion rate compared to oRC (all p < 0.001). No significant differences in terms of LOS between the ICUD vs. ECUD vs. ORC were recorded. RARC patients demonstrated better scores in fatigue, insomnia, pain, physical functioning, and role functioning-according to QoL assessment-compared to ORC at early follow-up, despite no difference at baselines. Finally, at network metanalysis, ICUD (OR = 0.74, p < 0.001) but not ECUD (OR = 0.92, p < 0.08) yielded a lower rate of high-grade 90-day complications compared to ORC despite longer OT (MD = 89.56, p = 0.0351). Conclusions: RARC represents a safe and feasible option to reduce perioperative bleeding with no definitive impact on LOS compared to ORC. Interestingly, ICUD may reduce the burden of 90-day complications to a greater extent than ECUD. Nonetheless, surgeons should be aware of the extended OT and steep learning curve of ICUD. Finally, RARC may provide some short-term benefits in terms of QoL, but more research is needed to determine its long-term effects.

Robotic salvage partial nephrectomy following surgical and ablative therapies.

PURPOSE: Partial nephrectomies in the salvage setting after ablative or surgical therapy remain challenging cases that are underreported in the literature (1-5). The aim of this video is to demonstrate techniques for robotic salvage partial nephrectomy to manage recurrent renal cell carcinoma (RCC) after failed prior partial nephrectomy and primary cryotherapy. MATERIALS AND METHODS: A 55-year-old man after previous robotic-assisted right partial nephrectomy presented with a 2.5 cm locally recurrent renal mass abutting the collecting system. A 59-year-old man with right renal cell carcinoma initially treated with cryoablation presented local recurrence. CT imaging demonstrated 2.6 cm right renal mass consistent with tumor recurrence at previous treatment site. RESULTS: Both procedures were completed in under 180 minutes. Clamp time was 22 minutes after the previous partial nephrectomy and 25 minutes after previous cryotherapy. There were no perioperative complications. Pathology in both cases demonstrated pT1a clear cell RCC with negative margins. Both patients have since no evidence of recurrent disease on follow-up imaging at 1 and 2 years, respectively. CONCLUSIONS: Salvage robotic partial nephrectomy should be considered as a feasible treatment option after failure of initial therapy-surgical or ablative. A salvage procedure is often more challenging than its standard therapy-naïve counterpart due to development of dense inflammation after previous interventions. Despite this, robotic partial nephrectomies in the salvage setting can be safely carried out with good surgical outcomes, particularly when utilizing intraoperative ultrasound to identify tumor margins and key anatomy.

Evaluation of the ecological risk of pesticide residues from the European LUCAS Soil monitoring 2018 survey.

The 2018 LUCAS (Land Use and Coverage Area frame Survey) Soil Pesticides survey provides a European Union (EU)-scale assessment of 118 pesticide residues in more than 3473 soil sites. This study responds to the policy need to develop risk-based indicators for pesticides in the environment. Two mixture risk indicators are presented for soil based, respectively, on the lowest and the median of available No Observed Effect Concentration (NOECsoil,min and NOECsoil,50) from publicly available toxicity datasets. Two further indicators were developed based on the corresponding equilibrium concentration in the aqueous phase and aquatic toxicity data, which are available as species sensitivity distributions. Pesticides were quantified in 74.5% of the sites. The mixture risk indicator based on the NOECsoil,min exceeds 1 in 14% of the sites and 0.1 in 23%. The insecticides imidacloprid and chlorpyrifos and the fungicide epoxiconazole are the largest contributors to the overall risk. At each site, one or a few substances drive mixture risk. Modes of actions most likely associated with mixture effects include modulation of acetylcholine metabolism (neonicotinoids and organophosphate substances) and sterol biosynthesis inhibition (triazole fungicides). Several pesticides driving the risk have been phased out since 2018. Following LUCAS surveys will determine the effectiveness of substance-specific risk management and the overall progress toward risk reduction targets established by EU and UN policies. Newly generated data and knowledge will stimulate needed future research on pesticides, soil health, and biodiversity protection. Integr Environ Assess Manag 2024;00:1-15. © 2024 The Authors.

Major adverse cardiovascular events related to phosphodiesterase 5 inhibitors: analysis of real-life data from Eudra-Vigilance database.

BACKGROUND: Phosphodiesterase 5 inhibitors (PDE5i) are the standard medical treatment for erectile dysfunction. Aim of our study was to evaluate the rate of major adverse cardiovascular events (MACE) reported during PDE5i treatment based on Eudra-Vigilance (EV) reports. METHODS: EV database is the system for managing and analyzing data on suspected adverse reactions to medicines which have been authorized or being studied in clinical trials in the European Economic Area. MACE are defined as non-fatal stroke, non-fatal myocardial infarction, non-fatal congestive heart failure, revascularization after aorto-coronary graft bypass and cardiovascular death. We recorded the number of MACE for sildenafil, tadalafil, vardenafil, avanafil per category and severity until 1st July 2023. Pooled Relative Risk (PRR) was used to compare data between drugs. RESULTS: Overall, 951 MACE events were reported. Most of them were observed in younger patients <65 years old (452/951 events, 48%). Overall, 377/8939 (4%) MACE events were observed for sildenafil, 221/5213 (4%) for tadalafil, 50/1029 (4%) for vardenafil and no events for avanafil. No significative differences were reported comparing sildenafil and tadalafil (PRR 0.71-0.99, IQR 0.61-1.35, P>0.05), neither sildenafil vs. vardenafil (PRR 0.68-0.79, IQR 0.43-1.55, P>0.05), neither tadalafil vs. vardenafil (PRR 0.77-0.95, IQR 0.64-1.30. P>0.05) even when compared for age. Comparison between different classes of age showed MACE were more frequent in patients younger than 65 years old taking sildenafil and tadalafil when compared to patients older than 85 years old (PRR 0.02-0.11. IQR 0.01-0.40. P<0.01) and when compared to patients in 65-85 class of age (PRR 0.02-0.12, IQR 0.01-0.95, P<0.01). CONCLUSIONS: Real life data is consistent with MACE related to PDE5i. PDE5is are infrequently (<5%) associated with MACE. However, risk seems higher in younger patients, particularly for sildenafil (452/951 events, 48%). Clinicians should consider these data when prescribing PDE5i especially in young patients.

Tissue-Based Genomic Testing in Prostate Cancer: 10-Year Analysis of National Trends on the Use of Prolaris, Decipher, ProMark, and Oncotype DX.

BACKGROUND: Prostate cancer (PCa) management is moving towards patient-tailored strategies. Advances in molecular and genetic profiling of tumor tissues, integrated with clinical risk assessments, provide deeper insights into disease aggressiveness. This study aims to offer a comprehensive overview of the pivotal genomic tests supporting PCa treatment decisions, analyzing-through real-world data-trends in their use and the growth of supporting literature evidence. METHODS: A retrospective analysis was conducted using the extensive PearlDiver™ Mariner database, which contains de-identified patient records, in compliance with the Health Insurance Portability and Accountability Act (HIPAA). The International Classification of Diseases (ICD) and Current Procedural Terminology (CPT) codes were employed to identify patients diagnosed with PCa during the study period-2011 to 2021. We determined the utilization of primary tissue-based genetic tests (Oncocyte DX®, Prolaris®, Decipher®, and ProMark®) across all patients diagnosed with PCa. Subsequently, within the overall PCa cohort, patients who underwent radical prostatectomy (RP) and received genetic testing postoperatively were identified. The yearly distribution of these tests and the corresponding trends were illustrated with graphs. RESULTS: During the study period, 1,561,203 patients with a PCa diagnosis were recorded. Of these, 20,748 underwent tissue-based genetic testing following diagnosis, representing 1.3% of the total cohort. An increasing trend was observed in the use of all genetic tests. Linear regression analysis showed a statistically significant increase over time in the use of individual tests (all p-values < 0.05). Among the patients who underwent RP, 3076 received genetic analysis following surgery, representing 1.27% of this group. CONCLUSIONS: Our analysis indicates a growing trend in the utilization of tissue-based genomic testing for PCa. Nevertheless, they are utilized in less than 2% of PCa patients, whether at initial diagnosis or after surgical treatment. Although it is anticipated that their use may increase as more scientific evidence becomes available, their role requires further elucidation.

Single port robot-assisted pyeloplasty: An early comparative outcomes analysis.

BACKGROUND: The treatment paradigm for ureteropelvic junction obstruction (UPJO) has shifted towards minimally invasive pyeloplasty. A comparison Single Port (SP) and Multi Port (MP) robot-assisted pyeloplasty (RAP) was performed. METHODS: Data from consecutive patients undergoing SP RAP or MP RAP between January 2021 and September 2023 were collected and analysed. Co-primary outcomes were length of stay (LOS), Defense and Veterans Pain Rating Scale (DVPRS), and narcotic dose. The choice of the robotic system depended on the surgeon's preference and availability of a specific robotic platform. RESULTS: A total of 10 SP RAPs and 12 MP RAPs were identified. SP RAP patients were significantly younger [23 years (20-34)] than MP RAP [42 years (35.5-47.5), p < 0.01]. No difference in terms of OT (p = 0.6), LOS (p = 0.1), DVPRS (p = 0.2) and narcotic dose (p = 0.1) between the two groups was observed. CONCLUSIONS: SP RAP can be implemented without compromising surgical outcomes and potentially offering some clinical advantages.

Implementation of single-port robotic urologic surgery: experience at a large academic center.

The Single-Port (SP) robotic system is increasingly being implemented in the United States, allowing for several minimally invasive urologic procedures to be performed. The present study aims to describe our single-center experience since the adoption of the SP platform. We retrospectively collected and analyzed consecutive SP cases performed at a major teaching hospital in the Midwest (Rush University Medical Center) from December 2020 to December 2023. Demographic variables were collected. Surgical and pathological outcomes were analyzed in the overall cohort and for each type of procedure. The study timeframe was divided into two periods to assess the evolution of SP technical features over time. In total, 160 procedures were performed, with robot-assisted radical prostatectomy (RARP) being the most common (49.4%). Overall, 54.4% of the procedures were extraperitoneal, with a significantly higher adoption of this approach in the second half of the study period (30% vs 74.3%, p < 0.001). A "plus one" assistant port was adopted in 38.1% of cases, with a shift towards a "pure" single-port surgery in the most recent procedures (21.1% vs 76.7%, p < 0.001). The median LOS was 33.5 h (30-48), with a rate of any grade and CD ≥ 3 postoperative complications of 9.4% and 2.5%, respectively, and a 30-day readmission rate of 1.9%. SP robotic surgery can be safely and effectively implemented for various urologic procedures. With increasing experience, the SP platform allows shifting away from transperitoneal procedures, potentially minimizing postoperative pain, and shortening hospital stay and postoperative recovery.
