Comparison of urological outcomes and quality of life after pelvic exenteration: partial vs radical cystectomy.

OBJECTIVE: To compare perioperative morbidity, functional and quality-of-life (QoL) outcomes in patients with partial cystectomy vs radical cystectomy as part of pelvic exenteration. PATIENTS AND METHODS: Retrospective analysis of a prospectively maintained database of pelvic exenteration patients (1998-2021) was conducted in a single centre. Study outcomes included postoperative complications, quality-of-life, functional and stoma-related outcomes. The 36-item Short-Form Health Survey Physical and Mental Health Components, Functional Assessment of Cancer Therapy-Colorectal questionnaires and Distress Thermometer were available pre- and postoperatively. QoL outcomes were compared at the various time points. Stoma embarrassment and care scores were compared between patients with a colostomy, urostomy, and both. RESULTS: Urological complications were similar between both groups, but patients with partial cystectomy experienced less wound-related complications. Overall, 34/81 (42%) partial cystectomy patients reported one or more long-term voiding complication (i.e., incontinence [17 patients], frequency [six], retention [three], high post-voiding residuals [10], permanent suprapubic catheter/indwelling catheter [14], recurrent urinary tract infection [nine], percutaneous nephrostomy [three], progression to urostomy [three]). The QoL improved following surgery in both the partial and radical cystectomy groups, differences between cohorts were not significant. Patients with two stomas reported higher embarrassment scores than patients with one stoma, although this did not result in more difficulties in stoma care. CONCLUSIONS: Partial cystectomy patients have fewer postoperative wound-related complications than radical cystectomy patients, but often experience long-term voiding issues. The QoL outcomes are similar for both cohorts, with significant improvement following surgery.

Prospective cohort study investigating quality of life outcomes following multi-speciality robotic-assisted surgery.

INTRODUCTION: Despite recent evidence on the surgical outcomes of robotic-assisted surgery (RAS), other patient centre outcomes, including quality of life (QOL), are lacking. This study aims to examine changes in QoL trajectories following RAS across different surgical specialities. PATIENTS AND METHODS: A prospective cohort study was conducted for patients undergoing urologic, cardiothoracic, colorectal or benign gynaecological RAS, between June 2016 and January 2020 at a tertiary referral hospital in Australia. QoL was measured using the 36-item Short-Form Health Survey at pre-operative, 6 weeks and 6 months postoperatively. Physical and mental summary scores and utility index were primary outcomes, and sub-domains were secondary outcomes. STATISTICAL ANALYSIS USED: Mixed-effects linear regressions were used to determine changes in QoL trajectories. RESULTS: Of the 254 patients undergoing RAS, 154 underwent urologic, 36 cardiothoracic, 24 colorectal and 40 benign gynaecological surgery. Overall, the average age was 58.8 years and most patients were male (75.1%). Physical summary scores significantly decreased from pre-operative to 6 weeks' post-operative in urologic and colorectal RAS; with all surgical specialities at least returning to pre-operative levels within 6 months postoperatively. Mental summary scores consistently increased from pre-operative to 6 months postoperatively for colorectal and gynaecological RAS. CONCLUSIONS: RAS contributed to positive changes in QoL, with physical health returning to the pre-operative level and mental health improvements across specialities, in the short term. While degrees of post-operative changes varied amongst specialities, significant improvements demonstrate benefits in RAS.

Laparoscopic donor nephrectomy-Technique and peri-operative outcomes in an Australian transplant center.

INTRODUCTION: Demand for donor kidneys far exceeds the availability of organs from deceased donors. Living donor kidneys are an important part of addressing this shortfall, and laparoscopic nephrectomy is an important strategy to reduce donor morbidity and increase the acceptability of living donation. AIM: To retrospectively review the intraoperative and postoperative safety, technique, and outcomes of patients undergoing donor nephrectomy at a single tertiary hospital in Sydney, Australia. METHOD: Retrospective capture and analysis of clinical, demographic, and operative data for all living donor nephrectomies performed between 2007 and 2022 at a single University Hospital in Sydney, Australia. RESULTS: Four hundred and seventy-two donor nephrectomies were performed: 471 were laparoscopic, two of which were converted from laparoscopic to open and hand-assisted nephrectomy, respectively, and one (.2%) underwent primary open nephrectomy. The mean warm ischemia time was 2.8 min (±1.3 SD, median 3 min, range 2-8 min) and the mean length of stay (LOS) was 4.1 days (±1.0 SD). The mean renal function on discharge was 103 µmol/L (±23.0 SD). Seventy-seven (16%) patients had a complication with no Clavien Dindo IV or V complications seen. Outcomes demonstrated no impact of donor age, gender, kidney side, relationship to the recipient, vascular complexity; or surgeon experience, on complication rate or LOS. CONCLUSION: Laparoscopic donor nephrectomy is a safe and effective procedure with minimal morbidity and no mortality in this series.

Detailed cost of robotic-assisted surgery in the Australian public health sector: from implementation to a multi-specialty caseload.

BACKGROUND: A barrier to the uptake of robotic-assisted surgery (RAS) continues to be the perceived high costs. A lack of detailed costing information has made it difficult for public hospitals in particular to determine whether use of the technology is justified. This study aims to provide a detailed description of the patient episode costs and the contribution of RAS specific costs for multiple specialties in the public sector. METHODS: A retrospective descriptive costing review of all RAS cases undertaken at a large public tertiary referral hospital in Sydney, Australia from August 2016 to December 2018 was completed. This included RAS cases within benign gynaecology, cardiothoracic, colorectal and urology, with the total costs described utilizing various inpatient costing data, and RAS specific implementation, maintenance and consumable costs. RESULTS: Of 211 RAS patients, substantial variation was found between specialties with the overall median cost per patient being $19,269 (Interquartile range (IQR): $15,445 to $32,199). The RAS specific costs were $8828 (46%) made up of fixed costs including $4691 (24%) implementation and $2290 (12%) maintenance, both of which are volume dependent; and $1848 (10%) RAS consumable costs. This was in the context of 37% robotic theatre utilisation. CONCLUSIONS: There is considerable variation across surgical specialties for the cost of RAS. It is important to highlight the different cost components and drivers associated with a RAS program including its dependence on volume and how it fits within funding systems in the public sector.

Incidence, Predictive Factors and Preventive Measures for Inguinal Hernia following Robotic and Laparoscopic Radical Prostatectomy: A Systematic Review.

PURPOSE: Inguinal hernia is a known sequel of radical prostatectomy which contributes to patient morbidity and health care expenditure. In this systematic review we evaluated the incidence of inguinal hernia associated with minimally invasive radical prostatectomy, in addition to predictive factors and preventive measures. MATERIALS AND METHODS: We searched PubMed® and Embase® between 2000 and February 2018 using the search terms inguinal hernia and radical prostatectomy. RESULTS: In concordance with search terms and selection criteria we identified a total of 155 reports with 27 studies eligible for inclusion. Collated results demonstrated a variable prevalence of inguinal hernia after laparoscopic radical prostatectomy and robotic assisted radical prostatectomy ranging from 4.3% to 8.3% and from 3% to 19.4 %, respectively. There was a higher mean prevalence of inguinal hernia after robotic assisted prostatectomy. Factors predicting inguinal hernia following minimally invasive radical prostatectomy included low body mass index, poor stream and straining prior to prostatectomy detected on symptom score instruments, a patent processus vaginalis or an intraoperative incidental inguinal hernia. Herniotomy or herniorrhaphy with onlay mesh repair was the most commonly reported intraoperative repair technique at the time of minimally invasive radical prostatectomy. Recurrence of repaired incidental hernia is rare. CONCLUSIONS: Inguinal hernia is common after minimally invasive radical prostatectomy. There is a lack of high level evidence to clarify risk factors and preventive strategies for inguinal hernia after minimally invasive radical prostatectomy. There is a justification for randomized controlled trials to further evaluate this under recognized clinical problem.

Robotic transmural ablation of bladder tumors using high-intensity focused ultrasound: Experimental study.

OBJECTIVES: To evaluate the feasibility of robot-assisted laparoscopic high-intensity focused ultrasound for targeted, extravesical, transmural, full-thickness ablation of intact bladder wall and tumor. METHODS: In three fresh cadavers and one acute porcine model, the transperitoneal robotic approach was used to mobilize the bladder and create a midline cystotomy. "Mimic" bladder tumors (2 tumors/case) were created by robotically suturing a piece of striated muscle (2.5 × 2.5 cm) to the luminal, urothelial surface of the bladder wall. The cystotomy was suture-repaired and bladder distended with 250 mL saline. A laparoscopic high-intensity focused ultrasound probe was robotically placed extravesically in direct contact with the serosal surface of the bladder wall to image the "mimic" tumor. Targeted, transmural, full-thickness high-intensity focus ultrasound ablation of the "mimic" tumor and adjacent bladder was carried out under real-time ultrasound and robotic monitoring. Untreated areas of the bladder served as a comparison. Post-procedure, gross and microscopic examinations were carried out. RESULTS: Laparoscopic high-intensity focused ultrasound ablation was feasible for all "mimic" tumors (100%). Real-time ultrasound clearly visualized the "mimic" tumor. Simultaneous display of the pre-planning and real-time treatment ultrasound images confirmed targeting precision. Mean operative room times for ultrasound localization, laparoscopic high-intensity focused ultrasound probe coupling, high-intensity focus ultrasound ablation, and total procedure were 3, 5, 6 and 60 min, respectively. On necropsy, no thermal/mechanical injuries occurred to the untreated bladder wall, adjacent organs or ureters. Gross inspection distinguished the treated from untreated areas. Histopathology confirmed sharply demarcated thermal coagulative necrosis and shrinkage effects between the treated and untreated areas. CONCLUSIONS: Laparoscopic extravesical high-intensity focus ultrasound for transmural, full-thickness targeted ablation of intact bladder wall and tumor is feasible. This has implications for bladder-sparing surgery in select patients with solitary muscle-invasive bladder cancer.

Novel kidney segmentation system to describe tumour location for nephron-sparing surgery.

PURPOSE: To propose a novel system based on segmental renal anatomy for objectively reporting location of clinical T1 masses for nephron-sparing surgery. METHODS: The kidney was subdivided into 12 standard segments, based on the computed tomography images. In 103 patients (105 cT1 tumours), three blinded radiologists (A, B, and C) prospectively reported segmental tumour location, size, and tumour-feeding arteries. Baseline, peri-operative, and post-operative data of 98 patients who underwent partial nephrectomy (PN) were prospectively collected, and the correlation between segmental tumour location and peri-operative data was evaluated. Kappa statistics were used to measure the inter-observer agreements. RESULTS: Tumour location could be assigned to the defined renal segment in all cases. Median tumour size was 2.8 cm (range 0.6-5.8). Inter-observer concordance was as follows: A versus B 0.82 (95% CI 0.74-0.90); A versus C 0.89 (95% CI 0.83-0.95); and B versus C 0.84 (95% CI 0.76-0.92). First, second, third, and fourth segments were involved by the tumour in 23, 39, 17, and 21% of cases, respectively. Number of segments involved by the tumour correlated with tumour size (p = 0.007), number of tumour-feeding arteries (p = 0.001), estimated blood loss during PN (p = 0.03), and trended towards higher post-operative complication rate (p = 0.07). Tumour-feeding arteries were identifiable in 80 patients (76%). CONCLUSIONS: Kidney segmentation (KS) system is an objective and reproducible radiologic method of universally reporting tumour location according to 12 renal segments. By adding descriptive information on tumour characteristics in candidates for nephron-sparing surgery, this novel KS system could serve as an adjunct to current nephrometry systems.

Trans-rectal ultrasound visibility of prostate lesions identified by magnetic resonance imaging increases accuracy of image-fusion targeted biopsies.

PURPOSE: To compare the diagnostic yield of targeted prostate biopsy using image-fusion of multi-parametric magnetic resonance (mp-MR) with real-time trans-rectal ultrasound (TRUS) for clinically significant lesions that are suspicious only on mp-MR versus lesions that are suspicious on both mp-MR and TRUS. METHODS: Pre-biopsy MRI and TRUS were each scaled on a 3-point score: highly suspicious, likely, and unlikely for clinically significant cancer (sPCa). Using an MR-TRUS elastic image-fusion system (Koelis), a 127 consecutive patients with a suspicious clinically significant index lesion on pre-biopsy mp-MR underwent systematic biopsies and MR/US-fusion targeted biopsies (01/2010-09/2013). Biopsy histological outcomes were retrospectively compared with MR suspicion level and TRUS-visibility of the MR-suspicious lesion. sPCa was defined as biopsy Gleason score ≥7 and/or maximum cancer core length ≥5 mm. RESULTS: Targeted biopsies outperformed systematic biopsies in overall cancer detection rate (61 vs. 41 %; p = 0.007), sPCa detection rate (43 vs. 23 %; p = 0.0013), cancer core length (7.5 vs. 3.9 mm; p = 0.0002), and cancer rate per core (56 vs. 12 %; p < 0.0001), respectively. Highly suspicious lesions on mp-MR correlated with higher positive biopsy rate (p < 0.0001), higher Gleason score (p = 0.018), and greater cancer core length (p < 0.0001). Highly suspicious lesions on TRUS in corresponding to MR-suspicious lesion had a higher biopsy yield (p < 0.0001) and higher sPCa detection rate (p < 0.0001). Since majority of MR-suspicious lesions were also suspicious on TRUS, TRUS-visibility allowed selection of the specific MR-visible lesion which should be targeted from among the multiple TRUS suspicious lesions in each prostate. CONCLUSIONS: MR-TRUS fusion-image-guided biopsies outperformed systematic biopsies. TRUS-visibility of a MR-suspicious lesion facilitates image-guided biopsies, resulting in higher detection of significant cancer.

Real-time transrectal ultrasonography-guided hands-free technique for focal cryoablation of the prostate.

OBJECTIVES: To describe, step-by-step, our hands-free technique for focal cryoablation of prostate cancer. MATERIALS AND METHODS: After detailed discussion of its limitations and benefits, consent was obtained to perform focal cryoablation in patients with biopsy-proven unilateral low- to intermediate-risk prostate cancer. The procedure was performed transperineally, using a hands-free technique (without an external grid template) under real-time bi-plane transrectal ultrasonography (TRUS) guidance, using an argon/helium-gas-based third generation cryoablation system. Follow-up consisted of validated questionnaires, physical examination, PSA measures, multiparametric TRUS and/or magnetic resonance imaging (MRI) and mandatory biopsy. RESULTS: The important steps for achieving safety, satisfactory oncological and functional outcomes included: patient selection, including TRUS/MRI fusion target biopsy; thermocouple and cryoprobe placement with a hands-free technique, allowing delivery in unrestricted angulations according to the prostatic contour, the course of the neurovascular bundle and the rectal wall angle; and hands-free bi-plane TRUS probe manipulation to facilitate real-time monitoring of anatomical landmarks at the ideal angle of the image plane. To achieve a lethal temperature in the known cancer area, while preserving the urinary sphincter, neurovascular bundle, urethra and rectal wall, continuous intraoperative control of the thermocouple temperatures was necessary, as were real-time TRUS monitoring of ice-ball size, control of the energy delivered and the use of a warming urethral catheter. CONCLUSION: We have described step-by-step the focal cryoablation of prostate cancer using a hands-free technique. This technique facilitates the effective delivery of cryoprobes and the intra-operative real-time quick manipulation of the TRUS probe.

Denonvilliers' space expansion by transperineal injection of hydrogel: implications for focal therapy of prostate cancer.

We developed and assessed a technique of: (i) expanding Denonvilliers' space by hydrogel (polyethylene glycol) during focal cryoabation; and (ii) temperature mapping to ensure protection of the rectal wall. In a fresh cadaver, 20 cc of hydrogel was injected transperineally into Denonvilliers' space under transrectal ultrasound guidance. Successful expansion of Denonvilliers' space was achieved with a range of 9-11 mm thickness covering the entire posterior prostate surface. Two freeze-thaw cycles were used to expand the iceball reaching the rectal wall as an end-point. Intraoperative transrectal ultrasound monitoring and temperature mapping in Denonvilliers' space by multiple thermocouples documented real-time iceball expansion up to 10 mm beyond the prostate, and safety in protecting the rectal wall from thermal injury. The lowest temperatures of the thermocouples with a distance of 0 mm, 5 mm and 10 mm from the prostate were: -35°C, -18°C and 0°C (P < 0.001), respectively. In gross and microscopic examination, the hydrogel mass measured 11 × 40 × 34 mm, which was identical to the intraoperative transrectal ultrasound measurements, there was no infiltration of the hydrogel into the rectal wall or prostate and no injury to the pelvic organs. In conclusion, the expansion of Denonvilliers' space by transperineal injection of hydrogel is feasible and a promising technique to facilitate energy-based focal therapy of prostate cancer.

Intraoperative ultrasonography with a surgeon-manipulated microtransducer during robotic radical prostatectomy.

Intraoperative transrectal ultrasonography during laparoscopic radical prostatectomy has been reported to lead to a reduction in surgical margin rates. However, the use of a surgeon-controlled ultrasound probe that allows for precise manipulation and direct interpretation of the image by a console surgeon has yet to be studied. The aim of the present study was to show initial feasibility using the microtransducer with 9-mm scan length controlled by the console surgeon during robot-assisted radical prostatectomy in 10 patients. The transducer is designed as a drop-in probe with a flexible cord for insertion through a laparoscopic port, and is controlled by a robotic arm with the ultrasonographic image shown as a console Tile-pro display. Intraoperative localization of the biopsy-proven cancerous hypoechoic lesion was feasible in four out of four cases. The microtransducer facilitated identification of the bladder neck as well as the appropriate level of neurovascular bundle release. Negative surgical margin was achieved in all 10 cases (100%), even though five of 10 patients (50%) had extraprostatic (pT3) disease. Recovery of erectile function and continence was encouraging. In conclusion, intraoperative ultrasound navigation using a drop-type microtransducer is a novel technique that could enhance the incremental value of the standard information.

eHealth literacy in prostate cancer: A systematic review.

OBJECTIVE: This systematic review (PROSPERO ID: CRD42022226375) aimed to identify the eHealth literacy of men with prostate cancer, and their caregivers. METHODS: 8 databases (MEDLINE, SCOPUS, EMBASE, Web Of Science, PsycINFO, ERIC, CINAHL, Cochrane CENTRAL) and grey literature sources (e.g. Google Scholar) were searched from inception to December 2023. Articles were included if assessing eHealth/digital literacy of men with prostate cancer, or their carers', and health outcome associations. Formats such as case reports, and review papers were excluded. Records and full texts underwent independent screening and data extraction. Author disagreements were resolved by discussion. The Mixed Methods Appraisal Tool (MMAT) was used to appraise included literature, with narrative synthesis of results. RESULTS: 21,581 records were retrieved, with 7 articles satisfying inclusion criteria. A heterogenous field was characterised with lack of modern eHealth literacy measurement tools identified. Results suggest novice eHealth literacy using web 1.0 technologies. Non-validated measures of literacy demonstrate mixed results, while health outcome effects limited in scope and reliability. CONCLUSION: Prostate cancer survivors' eHealth literacy levels is likely novice, and requires further investigation. PRACTICE IMPLICATIONS: Digital technologies/resources implemented as part of patient communication practices should be vetted for quality, and tailored to patients' eHealth literacy abilities and/or needs.

Robotic-assisted retroperitoneal lymph node dissection for stage II testicular cancer.

Objective: To evaluate the perioperative as well as early oncological outcomes of patients undergoing robotic retroperitoneal lymph node dissection for treatment of testicular cancer. Methods: We conducted a prospective consecutive case series of patients undergoing robotic assisted retroperitoneal lymph node dissection for metastatic testicular cancer between May 2018 and July 2021 at our institution. Data were collected on patient and tumour characteristics, intraoperative and postoperative parameters, and functional and oncological outcomes. Descriptive statistics are presented. Results: Nineteen patients were identified; 18 (94.7%) completed the procedure robotically and one was converted to open surgery; 78.9% of patients had stage ≥IIB and 12 (63.2%) patients had undergone prior chemotherapy. The median operative time was 300 (interquartile range [IQR] 240-315) min. Median blood loss was 100 (IQR 50-175) mL. Median length of stay was 2 (range 1-11) days. All robotically completed patients commenced diet and passed flatus on Day 1 and were discharged by Day 3. The median lymph node yield was 40.5 (IQR 38-51) nodes. All patients undergoing nerve-sparing procedures recovered antegrade ejaculatory function. One patient had a Clavien-Dindo III complication (chylous ascites requiring drainage). At a median follow-up of 22.3 (IQR 16.3-24.9) months, one patient developed retroperitoneal recurrence, which was successfully treated with second-line chemotherapy; no other patients have had recurrences. Conclusion: Robotic retroperitoneal lymph node dissection is a safe and feasible alternative to open surgery in appropriately selected patients, offering low morbidity. Early oncological outcomes are promising. Larger cohorts and longer follow-ups are required to validate our institution's findings.

Pelvic exenteration for locally advanced and recurrent prostate cancer.

Locally advanced or recurrent prostate cancer which invades adjacent pelvic organs, bone or other soft tissue structures is a rare situation. This study aimed to report the outcomes of ten consecutive patients who underwent total pelvic exenteration for prostate cancer at a high-volume specialist centre. Two patients had locally advanced primary tumours, while eight had locally recurrent prostate cancer. Median operating time, blood loss, ICU stay, and hospital stay was 12.2 h (range 9.6-13.8), 2500 ml (500-3000), 4.5 days (2-7) and 36 days (21-78), respectively. There was no inpatient, 30-day, or 90-day mortality. Six patients developed a Clavien-Dindo III complication. R0 resection was achieved in eight patients. Median follow up was 16 months (range 2-77). At last follow up, five patients were alive without disease. These findings suggest that pelvic exenteration for locally advanced and recurrent prostate cancer is safe and represents a potentially curative treatment option for highly selected patients.

Robotic-Assisted Bladder Diverticulectomy: Indications, Technique and Outcomes - a Case Series.

PURPOSE: This case series describes the experience and outcomes of multiple Australian surgeons performing robotic-assisted bladder diverticulectomy (RABD), highlighting the procedural effectiveness and safety, for both benign and malignant indications for diverticulectomy. METHODS: Outcomes were analysed from Thirteen experienced Australian urologists who performed RABD between 2016 and 2023. Retrospective analysis was performed on prospectively collected data which included patient demographics, diverticulum characteristics, surgical approaches, and post-operative outcomes. Surgical techniques included the extravesical and intravesical approaches, with the focus on maintaining oncological principles in cases of malignancy. RESULTS: A total of 28 patients underwent RABD, with the majority being male and a mean age of 63.9 years. All surgeons utilised a four port transperitoneal approach and opted for the extravesical dissection of the diverticular neck, one case utilised both extravesical and a trans-diverticular approach. Functional outcomes demonstrated symptomatic resolution in patients with non-malignant diverticula, while oncological outcomes indicated clear margins in 90% of malignant cases. The average length of the procedure was 106 minutes, with minimal blood loss and a mean hospital stay of 2.67 days. Early complications occurred in 14% with the majority Clavien-Dindo grade II . CONCLUSION: Robotic bladder diverticulectomy, predominantly via the transperitoneal extravesical approach, has emerged as a safe, effective, and reliable surgical intervention for both malignant and non-malignant bladder diverticula. The consistent surgical approach and excellent outcomes demonstrated in this case series reinforce the procedure's potential as a safe option, even in the setting of malignancy within a diverticulum.

Prostate swelling and shift during high intensity focused ultrasound: implication for targeted focal therapy.

PURPOSE: We quantified prostate swelling and the intraprostatic point shift during high intensity focused ultrasound using real-time ultrasound. MATERIALS AND METHODS: The institutional review board approved this retrospective study. Whole gland high intensity focused ultrasound was done in 44 patients with clinically localized prostate cancer. Three high intensity focused ultrasound sessions were required to cover the entire prostate, including the anterior zone (session 1), middle zone (session 2) and posterior zone (session 3). Computer assisted 3-dimensional reconstructions based on 3 mm step-section images of intraoperative transrectal ultrasound were compared before and after each session. RESULTS: Most prostate swelling and intraprostatic point shifts occurred during session 1. The median percent volume increase was 18% for the transition zone, 9% for the peripheral zone and 13% for the entire prostate. The volume percent increase in the transition zone (p <0.001), peripheral zone (p = 0.001) and entire prostate (p = 0.001) statistically depended on the volume of each area measured preoperatively. The median 3-dimensional intraprostatic shift was 3.7 mm (range 0.9 to 13) in the transition zone and 5.5 mm (range 0.2 to 14) in the peripheral zone. A significant negative linear correlation was found between the preoperative presumed circle area ratio, and the percent increase in prostate volume (p = 0.001) and shift (p = 0.01) during high intensity focused ultrasound. CONCLUSIONS: We quantified significant prostate swelling and shift during high intensity focused ultrasound. Smaller prostates and a smaller preoperative presumed circle area ratio were associated with greater prostate swelling and intraprostatic shifts. Real-time intraoperative adjustment of the treatment plan impacts the achievement of precise targeting during high intensity focused ultrasound, especially in prostates with a smaller volume and/or a smaller preoperative presumed circle area ratio.

Salvage focal and salvage total cryoablation for locally recurrent prostate cancer after primary radiation therapy.

OBJECTIVES: To present the oncological and functional outcomes of salvage focal (SFC) and salvage total (STC) cryoablation for recurrent prostate cancer (PCa) after failed primary radiotherapy. PATIENTS AND METHODS: From March 2003 to August 2010, 50 men with biopsy-proven unilateral (n = 25) or bilateral (n = 25) radio-recurrent PCa underwent SFC or STC, respectively. Patients were assessed after treatment by prostate-specific antigen (PSA) testing, transrectal ultrasonography, biopsy and questionnaires. Biochemical failure (BF) was defined using the Phoenix criteria (PSA nadir + 2 mg/mL). Data were prospectively collected and retrospectively analysed. RESULTS: The median pre-cryoablation PSA level and Gleason score were, respectively, 2.8 ng/mL and 7 for SFC, and 3.9 ng/mL and 7 for STC. The median follow-up was 31 and 53 months (P = 0.004) for SFC and STC, respectively. Oncological outcomes were as follows: no patient died; one patient who underwent STC developed bone metastases; eight patients who underwent SFC and three who underwent STC had BF and the 5-year BF-free survival rates were 54 and 86%, respectively. In those patients without BF, the mean PSA decreased by 86% for SFC and 90% for STC within the first year and remained stable. Functional outcomes were as follows: new onset urinary incontinence occurred in three (13%) patients in the STC group, whereas no patient in the SFC group developed incontinence (P = 0.10); Two of seven patients in the SFC group retained postoperative potency, but none of the four potent patients in the STC group recovered potency postoperatively (P = 0.48); one (4%) patient in the STC group developed a recto-urethral fistula, but none occurred in the SFC group (P = 0.48). CONCLUSIONS: SFC and STC are feasible and safe with acceptable mid-term oncological outcomes. For carefully selected patients, SFC is an option that could be associated with lower treatment-related morbidity compared with STC. Although longer follow-up and more patient numbers are needed, our initial oncological and functional outcomes of SFC and STC are encouraging.

What are the Most Important Objectives of Patients Undergoing Radical Prostatectomy? A Narrative 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.

Prostate cancer, online health information and communication technology - Bibliometric analysis of field with research frontiers.

OBJECTIVES: The purpose of this study is to conduct the first bibliometric analysis which examines eHealth communication technologies in prostate cancer care, and the utilization of internet-based health information and communication technology by men with prostate cancer. METHODS: Original articles were extracted from the Science Citation Index Expanded (SCI-E) on Web of Science (WOS) and analyzed concerning their distributions. Quantitative guidance directed investigation of findings from previous studies and trending issues within the field. The WOS, VOSViewer and CiteSpace IV were used for information analysis. RESULTS: 302 articles were included in the final analysis. There has been a 165 % increase in productivity over the past decade. The leading country by publication was the USA (145 articles = 48.02 %). Journals which published the highest number of original articles were the Journal of Medical Internet Research (6.95 %), and Patient Education and Counseling (4.64 %). DISCUSSION AND PRACTICE IMPLICATIONS: The field of research which examines utilization and impacts of internet-based health information on men with prostate cancer is growing and diverse. Research frontiers are 'Information quality and diversity', 'eHealth literacy', 'decision making', and 'survivorship and advanced disease'. Clinicians should be aware of several significant limitations which exist within the current field of research.

A Chance Finding of High Grade Prostate Cancer in a 35-Year-Old Male - A Case Report and Outcomes of Robotic Radical Prostatectomy in Young Men with Prostate Cancer.

Background: Prostate cancer is often considered a disease of older men and this indeed fits with its peak incidence between 65-79 years of age. Reports of prostate cancer in men younger than 40 years of age and the outcomes of this age group following treatment are few in the literature. Here, we present the case of an unusual diagnosis of high grade prostate cancer in a very young man and outline early outcomes following treatment with robotic-assisted radical prostatectomy. Case Presentation: A 35-year-old male, intermittently taking finasteride for hair loss, was found to have an elevated prostate-specific antigen (PSA) of 12.5ng/mL leading to an incidental diagnosis of high grade prostate cancer. Targeted trans-perineal prostate biopsy found Gleason 4+5=9 acinar adenocarcinoma, without cribriform architecture but with features suspicious for extracapsular extension. Robotic radical prostatectomy with bilateral pelvic lymph node dissection was performed and found Gleason 4+5=9 adenocarcinoma with focal cribriform architecture, extra prostatic extension and clear margins, stage pT3a N0 M0. PSA was undetectable at 12 months, continence was immediate, and the patient reported strong erections soon after surgery. Family history of prostate cancer and genetic testing were both negative. Conclusion: This case highlights that not all clinically significant cancers will be identified by following PSA screening guidelines starting at 50 years of age (or 40 years of age for men with a family history of prostate cancer). While high grade prostate cancer in a man less than 40 years of age is uncommon, the literature suggests the incidence is increasing. Our case alongside series in the literature indicate that these men have better functional outcomes and equal oncological outcomes with early surgical intervention for localized disease when compared to the older population.
