International Urology and Nephrology Nov 2023To assess the ChatGPT (Open AI) artificial intelligence platform's utility and accuracy as a patient education tool in robotic-assisted radical prostatectomy.
OBJECTIVES
To assess the ChatGPT (Open AI) artificial intelligence platform's utility and accuracy as a patient education tool in robotic-assisted radical prostatectomy.
MATERIALS AND METHODS
The ChatGPT 3.5 interface ( https://chat.openai.com/chat ) was interrogated and asked the 14 questions related to the frequency of complications of robotic-assisted radical prostatectomy as listed on British Association of Urological Surgeons (BAUS) patient information leaflet "Robotic-Assisted Laparoscopic Radical Prostatectomy)" published July 2021. The AI's responses to each question were tabulated, and compared alongside the official figures quoted from the BAUS information leaflet. A global assessment of the AI's response was also made for accuracy and relevance to patients.
RESULTS
Of the 14 questions asked, 11/14 (78.6%) of ChatGPT's quoted figures were considered concordant and comparable to those quoted by the BAUS patient information leaflet. 13/14 (92.9%) of ChatGPT's responses were globally assessed to contain accurate information, appropriate, and pertinent to a patient's potential enquiry.
CONCLUSION
ChatGPT is a powerful tool and is able to generate accurate and helpful information for patients seeking information regarding urological procedures and their potential complications. It is not, however, infallible, and urologists should remain vigilant in their patient interactions to any potential misinformation a patient may have gathered from it in their personal research prior to surgery.

European Urology Oncology Sep 2023Evidence on long-term oncological efficacy is available only for open radical prostatectomy but remains scarce for robot-assisted radical prostatectomy (RARP).
Prostate Cancer-specific and All-cause Mortality After Robot-assisted Radical Prostatectomy: 20 Years' Report from the European Association of Urology Robotic Urology Section Scientific Working Group.
BACKGROUND
Evidence on long-term oncological efficacy is available only for open radical prostatectomy but remains scarce for robot-assisted radical prostatectomy (RARP).
OBJECTIVE
To validate the long-term survival rates after RARP and provide stratified outcomes based on contemporary prostate cancer (PCa) risk-stratification tools.
DESIGN, SETTING, AND PARTICIPANTS
A retrospective analysis of the European Association of Urology (EAU) Robotic Urology Section Scientific Working Group international multicenter database for RARP was performed. Patients who underwent RARP at seven pioneer robotic urology programs in Europe and the USA between 2002 and 2012 were included.
OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS
The primary outcomes were PCa-specific mortality and all-cause mortality. The probability of cancer-specific survival (CSS) was estimated with the competing risks method, and the probability of overall survival (OS) was estimated with the Kaplan-Meier method.
RESULTS AND LIMITATIONS
A total of 9876 patients who underwent RARP between 2002 and 2012 were included. Within follow-up, 1071 deaths occurred and 159 were due to PCa. At 15 yr of follow-up, CSS and OS were 97.6% (97.2%, 98.0%) and 85.5% (84.6%, 86.4%), respectively. Stratified analyses based on EAU risk groups at diagnosis and pT stage showed favorable survival rates, with low-risk (n = 4601, 46.6%), intermediate-risk (n = 4056, 41.1%), and high-risk (n = 1219, 12.3%) patients demonstrating CSS rates of 99%, 98%, and 90% at 15 yr, respectively. Notably, patients with pT3a disease had similar survival outcomes to those with pT2 disease, with worse CSS in patients with pT3b PCa (98.9% vs 97.4% vs 86.5%). Multivariable analyses identified age, prostate-specific antigen, biopsy Gleason grade group, clinical T stage, and treatment year as independent predictors of worse oncological outcomes.
CONCLUSIONS
Our multicenter study with long-term follow-up confirms favorable survival outcomes after RARP for localized PCa. Patients with low- and intermediate-risk disease face a higher risk of mortality from causes other than PCa. On the contrary, high-risk patients have a significantly higher risk of PCa-specific mortality.
PATIENT SUMMARY
In the present study, we reported the outcomes of patients with prostate cancer (PCa) who underwent robot-assisted radical prostatectomy between 10 and 20 yr ago, and we found a very low probability of dying from PCa in patients with low- and intermediate-risk PCa.

Meta-Analysis Comparative Study Review
Comparative analysis of perioperative outcomes in obese patients undergoing robot-assisted radical prostatectomy (RARP) versus open radical prostatectomy (ORP): a systematic review and meta-analysis.
The purpose of this study was to conduct a comparative analysis of the perioperative outcomes associated with robot-assisted laparoscopic prostatectomy (RARP) versus open radical prostatectomy (ORP) in the obese population diagnosed with prostate cancer. We performed a comprehensive search in key databases such as PubMed, Embase, Web of Science, and the Cochrane Library, encompassing studies of all languages, with a final search date of April 2024. We also omitted articles that consisted of conference abstracts and content that was not pertinent to our study. The aggregated outcomes were evaluated utilizing the metrics of weighted mean differences (WMDs) and odds ratios (ORs). A sensitivity analysis was also integrated into our assessment. The meta-analysis was facilitated by employing Stata/MP version 18 software. Additionally, the study was duly registered with PROSPERO under the identifier: CRD 42024540216. This meta-analysis, which included five trials, shows that compared to ORP, RARP is associated with a reduced estimated blood loss (EBL) (WMD -445.77, 95%CI -866.08, -25.45; p = 0.038), a decreased transfusion rate (OR 0.17, 95%CI 0.13, 0.21; p < 0.001), and a diminished overall complication rate (OR 0.71, 95%CI 0.58, 0.86; p = 0.001). No statistically significant differences were found in operative time (OT) (WMD 1.88, 95%CI -46.53, 50.28; p = 0.939) or length of stay (LOS) (WMD -0.41, 95%CI -1.07, 0.25; p = 0.221). Among patients with obesity and prostate cancer, RARP demonstrates advantages over ORP by reducing estimated blood loss, transfusion requirements, and the incidence of complications. Notably, there were no significant differences in operative duration and hospital stay between the two surgical approaches. These findings suggest that RARP could be a preferable surgical option for obese individuals with prostate cancer.

PURPOSE
Comparing post-radical prostatectomy erectile function rates among different techniques has always been a challenge in urology. This difficulty is due to the heterogeneity of studies, mainly in relation to the type of erectile function classification criteria used. The aim is to apply a new evidence-gathering methodology, called reverse systematic review, to compare erectile function rates among retropubic radical prostatectomy, laparoscopic radical prostatectomy, and robot-assisted radical prostatectomy, considering the diversity of classification criteria.
METHODS
A search was carried out in eight databases between 2000 and 2020 through systematic review studies referring to retropubic radical prostatectomy, laparoscopic radical prostatectomy, or robot-assisted radical prostatectomy (80 systematic reviews). All references used in these systematic reviews were captured by referring to 910 papers in a global database called EVIDENCE. A total of 268 studies related to post-prostatectomy erectile function rates were selected for the final analysis, totaling 465 cohorts or reports referring to 131,350 patients.
RESULTS
Note that, 119 (25.6%) reports for retropubic radical prostatectomy, 143 (30.7%) reports for laparoscopic radical prostatectomy, and 203 (43.7%) reports for robot-assisted radical prostatectomy were found. Mean overall erectile function rates, respectively for retropubic radical prostatectomy, laparoscopic radical prostatectomy, and robot-assisted radical prostatectomy, were: 16%, 12%, and 35% at 1 month, 22%, 26%, and 42% in 3 months; 30%, 44%, and 54% at 6 months, 41%, 55%, and 59% at 12 months, and 58%, 52%, and 67% at more than 18 months. The most used erectile function criterion was Erection Sufficient for Intercourse (74.1%), followed by Sexual Health Inventory for Men > 21 (5.5%), and Sexual Health Inventory for Men > 16 (3.7%). Erection Sufficient for Intercourse showed the lowest discrepancy in erectile function rates in each period compared to the global average, for each technique, demonstrating less ability to influence the final results, favoring any of the techniques.
CONCLUSIONS
The reverse systematic review demonstrated that the robot-assisted radical prostatectomy showed higher rates of erectile function recovery at all times analyzed (1->18 months), in relation to the retropubic radical prostatectomy and laparoscopic radical prostatectomy. The Erection Sufficient for Intercourse criterion was the most used in the literature and showed the lowest bias capable of influencing the results and favoring any of the techniques and might be the fairest option for future comparisons.

BACKGROUND
Surgical management of large prostatic adenomas can be performed via open, endoscopic, or robotic approaches. A low-profile single-port (SP) robot was built to work in confined areas (ie, the bladder) and regionalize surgery.
OBJECTIVE
To describe the novel SP transvesical (TV) robot-assisted simple prostatectomy (RASP) and report clinical outcomes.
DESIGN, SETTING, AND PARTICIPANTS
SP TV RASP cases were performed in an academic hospital by two surgeons from 2019 to 2023. A total of 117 cases were performed, and data from patients with at least 12 mo of follow-up were analyzed. The inclusion criterion was severe obstructive urinary symptoms or catheter-dependent urinary retention due to large prostates with volume >80 ml.
SURGICAL PROCEDURE
The procedure consisted of two main steps through a single 3-cm suprapubic incision: first, enucleation of the adenoma, and second, a 360° bladder mucosal flap reconstruction. No drains or continuous bladder irrigation was used routinely.
MEASUREMENTS
Intraoperative parameters, pre- and postoperative uroflowmetry, and 1-yr clinical outcomes were assessed. We used descriptive statistics to analyze the data.
RESULTS AND LIMITATIONS
All procedures were completed successfully without additional ports or conversions. The median console time and estimated blood loss were 107 min and 100 ml, respectively. Transfusion rate was 0%. Intraoperative complications included two suspected air emboli attributed to high insufflation pressures. There were no major postoperative complications. In total, 95.8% were discharged within the first 24 h, with a median length of stay and pain score of 5 h and 3/10, respectively. There was persistent improvement in the median International Prostate Symptom Score and flow rate after 1 yr. The median Sexual Score Inventory for Men score was 20 at 12 mo. Our study is limited by its retrospective nature and cohort size.
CONCLUSIONS
SP TV RASP is a feasible alternative for the management of severe benign prostatic hyperplasia that promotes fast recovery and demonstrates 1-yr improvement in urinary function.
PATIENT SUMMARY
Single-port transvesical robot-assisted simple prostatectomy is a minimally invasive alternative for the treatment of large benign prostatic growth. A single robotic arm goes through a small incision in the skin and bladder to extract the obstructive prostatic tissue. Afterward, reconstruction of the area is done to decrease bleeding and improve postoperative symptoms. We found that patients recover quickly and have excellent clinical results with a low risk of complications.

Review
Systematic reviews (SR) produce the best evidence comparing open (RRP), laparoscopic (LRP), and robotic (RARP) radical prostatectomy (RP). However, the hyperfiltration of evidence generates very specific scenarios that reduce the power of extrapolation. To compare RP evidence regarding demographics using a new methodology called reverse systematic review (RSR). Between 2000 and 2020, 8 databases were searched for SR studies on RRP, LRP, or RARP. All references were captured and analyzed over time in 80 SR. Total of 1724 reports (n = 752, 43.7% for RARP; n = 559, 32.4% for RRP; n = 413, 23.9% for LRP) described 1,353,485 patients (881,719, 65.1% RRP; 366,006, 27.0% RARP; 105,760, 7.8% LRP). Patients/center/year was higher in RARP compared to LRP and RRP, median 50.0, 40.0, and 36.66, respectively, P < .001. Surgeons per study was lesser in RARP and LRP compared to RRP, median 2.0, 2.0, and 6.0, respectively, P < .001. Study duration and follow-up in years was shorter in RARP compared to LRP and RRP, median 2.6, 3.0, and 4.0, respectively, P < .001. Cumulative RARP reports predominate in North America (55.7%, n = 468) and Asia (47.8%, n =129), while LRP predominate in Europe (42.3%, n =230) and RRP in Oceania (45.1%, n = 23). After 2010 all continents began to accumulate more patients in the robotic approach. Potential biases related to shorter follow-up, greater volume centers, and surgeons were identified favoring the RARP. Analyzing the context of the available evidence is essential to compare techniques. Influenced by economic and scientific interests, robotic surgery was developed in centers with a higher volume of surgeries, characterizing potential biases when comparing techniques in the clinical shared decision.

BACKGROUND
Senhance Surgical System is a novel robotic platform used in University Hospital Centre Zagreb since February 2019. In this study, we present our 3-year experience with this platform.
PATIENTS AND METHODS
Data were prospectively collected for 200 patients who underwent extraperitoneal robotic radical prostatectomy (RRP) from May 2019 to March 2022.
RESULTS
The median age of the patients was 65 years, and the prostate-specific antigen was 6.9 ng/mL. Clinically, most of the patients had T1c stage. The estimated blood loss was 250 mL, and there were 6 conversions to laparoscopic and 2 to open prostatectomy. There were 15 early postoperative complications, 11 Clavien-Dindo classification grade I, 3 grade II and 1 grade IV. Functional outcomes in the first 150 patients: 140 patients (93.3%) had good urinary control. Thirteen patients underwent additional oncological treatment.
CONCLUSION
RRP performed with the Senhance robotic platform is a feasible and safe procedure with good initial results.

Review
Bladder neck contracture is a recognised complication associated with radical prostatectomy. The management can be challenging, especially when refractory to initial intervention strategies. For the patient, the burden of disease is high and continence status cannot be overlooked. This review serves to provide an overview of the management of this recognised clinical pathology. Consideration needs to be given to minimally invasive approaches such as endoscopic incision, injectables, implantable devices as well as major reconstructive surgery where the condition persists. For the latter, this can involve open and robotic surgery as well as use of grafts and artificial sphincter surgery. These elements underline the need for a tailored and a patient centred approach.

Review
BACKGROUND
Haemorrhage is a common complication following open simple prostatectomy and patients may sometimes require a blood transfusion. Tranexamic acid has been shown to reduce blood loss following transurethral resection of the prostate and open radical prostatectomy. This study evaluated the effect of perioperative intravenous administration of tranexamic acid on blood loss and blood transfusion rates in patients who had OSP for benign prostatic enlargement.
METHODOLOGY
This was a comparative study of patients with documented prostate glands 60g and above scheduled for OSP. Initial hematocrit was done a day before surgery. The patients were randomized into a tranexamic acid group, which received perioperative intravenous tranexamic acid and the no-TXA group which received placebo (0.9% saline). All patients had open simple retropubic prostatectomy. Final post-operative hematocrit was assessed 72 hours after surgery, and blood loss was calculated using the modified Gross formula (actual blood loss = estimated blood volume x change in hematocrit / mean hematocrit). The transfusion rate was documented.
RESULTS
Fifty-six patients participated in this study and were randomized into a tranexamic acid group and no-tranexamic acid group. The mean age of patients in the tranexamic acid group was 66.07 ±7.08 years and was comparable to the no- tranexamic acid group which was 66.50 ± 8.80 years (P = 0.842). The median total blood loss was lower in the tranexamic acid group (502mls, IQR 613) compared to the no-tranexamic acid group (801mls, IQR 1069). The difference in the median blood loss between the two groups was 299mls (U 275, P 0.055). The rate of blood transfusion was lower in the tranexamic acid group (6 patients, 21%) compared to the no tranexamic acid group (11 patients, 39%), (P = 0.146). There was no difference in complication rates between the two groups.
CONCLUSION
The use of tranexamic acid in patients undergoing open simple prostatectomy showed a trend towards reduced intraoperative blood loss and less need no tranexamic for blood transfusion. This is of clinical significance, especially in elderly patients with low cardiovascular reserve.

Review
PURPOSE
This study aimed to evaluate what objectives are most important to men undergoing radical prostatectomy to allow treating physicians to personalize perioperative counselling and improve patient quality of life outcomes.
MATERIALS AND METHODS
A predefined search protocol of the Medline and Embase databases was performed from database inception to May 2023. The search was limited to English language and full text. All articles with a specific consideration of patient objectives, preferences or reasons for decision to undergo radical prostatectomy were included for review.
RESULTS
Ten articles out of 375 screened met inclusion criteria for review. All 10 articles utilized a qualitative design and originated across 5 countries across the developed world. A common theme of men placing importance on having their tumor physically removed was found. Methodologies allowing free response beyond predefined categories identified a breadth of considerations including personal circumstance, personal belief and current function in the decision-making process. An investigation on radical prostatectomy performed robotically found some men placed preference on the quicker treatment time with surgery compared to radiation therapy, reflective of shorter recovery times with the robotic approach.
CONCLUSION
Variability in results across studies highlights the heterogeneity in patient preferences. Directed investigation of patient objectives with an open-ended questioning approach would personalize the perioperative experience and may improve patient satisfaction and quality of life outcomes.
