Gynaecological organ involvement in females undergoing radical cystectomy: a multicentre study.

OBJECTIVE: To report the incidence of malignancy in gynaecological organs removed during radical cystectomy (RC). PATIENTS AND METHODS: A retrospective multicentre study of 1600 RCs at three high-volume institutions between January 2009 and March 2022 was performed. Pathological findings in gynaecological organs in female RC specimens were reviewed. Multivariable logistic regression analyses were used to identify predictors of malignant gynaecological organ involvement (GOI) at time of RC. RESULTS: Overall, 302 females with a median (interquartile range) age of 68 (61-75) years underwent RC for clinical (c)Ta-T4 bladder cancer. In all, 56 patients (18.5%) received neoadjuvant chemotherapy. Malignant GOI was seen in 20 patients (6.6%); the most common single sites of GOI were the uterus (five patients) and vaginal wall (four), followed by cervix (one), and ovaries (one). Nine patients had involvement of more than one gynaecological organ. No females had a primary gynaecological malignancy detected incidentally at RC. Patients with GOI were more likely to have cT3/T4 stage (P < 0.001), preoperative hydronephrosis (P = 0.004), lymphovascular invasion (P = 0.002), and squamous cell carcinoma (P = 0.005) than those without GOI. On multivariable analysis, cT4 stage was an independent predictor of malignant GOI (odds ratio 88.3, 95% confidence interval 10.1-1214; P < 0.001). CONCLUSION: To our knowledge, we present the largest multi-institutional study examining malignant GOI in females with bladder cancer undergoing RC. The rate of GOI at the time of RC is low and associated with higher clinical stage. In the absence of clinical or radiological evidence of sexual organ involvement, our results do not support their routine removal at the time of RC.

Factors associated with pathological up-staging in MRI cT3a prostate cancer - a retrospective study from a high-volume centre.

INTRODUCTION: Multiparametric MRI (mpMRI) parameters of pT3a prostate cancer have not been examined in large cohort studies. Therefore, we aimed to identify factors associated with up-staging of mpMRI cT3a in post-operative histopathological confirmation. METHODS: Retrospective analysis of a prospectively maintained database of a single UK cancer centre. Only cT3a cases who underwent robotic-assisted radical prostatectomy (RARP) were included (N = 383). MRI and specimen histopathology was reviewed independently by expert uro-radiologists and uro-histopathologists, respectively. Factors included age, BMI, prostate-specific antigen (PSA) level, biopsy international society of urological pathology (ISUP) grade, Prostate Imaging Reporting & Data System (PI-RADS®) score, tumour size, tumour coverage of gland (%), gland weight and surgical margins were analysed as predictors of pT3a prostate cancer. RESULTS: N = 383. Mean age 66 years (58-71), mean BMI 27.1 kg/m2 (25.0-30.0). 314 (82.0%) cases down- unchanged or down-staged, and 69 (18.0%) cases upstaged. PSA level (P = 0.002), PI-RADS score (P < 0.001) and ISUP grade (P < 0.001) are positively associated with upstage categories. ISUP grade ≥3 (OR 5.45, CI 1.88, 9.29, P < 0.002), PI-RADS score ≥4 (OR 3.92, CI 1.88-9.29, P < 0.001) and tumour coverage (OR 1.06, CI 1.05-1.08, P < 0.001) significantly positively associated with upstaging disease, with concurrent decreased probability of downstaging (OR 0.55, 0.14, 0.44, respectively, P < 0.05). Tumour coverage was positively correlated with increasing positive surgical margins (P < 0.05). Capsular contact > 15 mm was very unlikely to be upstaged (OR 0.36, CI 0.21-0.62, P < 0.001), aligning with published results past the widely accepted significant level for extracapsular disease on MRI. CONCLUSION: The study has identified PSA level, ISUP, PI-RADS score, tumour volume and percentage coverage are key predictive factors in cT3a upstaging. This study uniquely shows tumour coverage percentage as a predictor of cT3a upstaging on mpMRI. ISUP is the strongest predictor, followed by PI-RADS score and tumour coverage of gland. Multi-institutional studies are needed to confirm our findings.

Assessment of routine same-day discharge surgery for robot-assisted radical prostatectomy.

INTRODUCTION: It is important for robotic surgery to be cost-effective, especially by reducing the length of stay (LOS). Therefore, we developed a protocol for day-case robot-assisted radical prostatectomy (RARP). This study aimed to validate this as a safe practice of care and to assess the potential benefits to the hospital and patient. METHODS: In this single-centre study, all patients booked for RARP between April 2022 and October 2022 were screened for suitability for day case. All tumour types were included. Exclusion criteria were a history of complex abdominal surgeries, salvage prostatectomy, body mass index (BMI) > 35 and patient living alone or > 150 km away from the hospital. All day-case RARPs were performed as a morning case with a protocol for review throughout the day with evening discharge if mobilising independently and eating/drinking well. The primary outcome of the study was success rate of discharge home on day of surgery (DOS) with secondary outcomes of readmissions and complications. A patient questionnaire was completed at home including both visual analogue scale (VAS) for pain and satisfaction rating. RESULTS: Forty-five patients underwent day-case RARP over a 6-month period with minimum of 30 days of follow-up. 41/45 (91%) had successful DOS discharge home. The four admissions overnight were due to dizziness, low oxygen saturation, intraoperative complications and a diagnosis of COVID-19. There were no readmissions and no 30-day complications. The most common issues at home were catheter discomfort and constipation with low mean VAS pain score and low nausea reported. The overall patient satisfaction rating was very high at 4.8/5, and 97% said they would recommend to a family member. The cost saving for the hospital was 400 pounds per patient. CONCLUSION: Day-case procedure is a viable, safe and efficient pathway for appropriately selected and counselled patients undergoing RARP.

Robot-assisted salvage seminal vesicle excision for isolated recurrence after low-dose-rate prostate brachytherapy.

OBJECTIVES: To report clinical and functional outcomes for patients who have undergone salvage robot-assisted seminal vesicle excision (RA-SVE) for the focal treatment of isolated seminal vesical (SV) recurrence after treatment for prostate cancer by low-dose-rate brachytherapy. PATIENTS AND METHODS: Patients with rising prostate-specific antigen (PSA) after low-dose-rate prostate brachytherapy (LDR-PB) underwent multi-parametric magnetic resonance imaging (mp-MRI) of the prostate and 11 C-Choline or 68 Ga-prostate-specific membrane antigen (68 Ga-PSMA) positron emission tomography/computed tomography (PET/CT) scan, followed by targeted transperineal biopsy of the prostate and SVs. Isolated SV recurrence were identified in 17 (0.38%) LDR-PB patients. These 17 patients were offered RA-SVE. RESULTS: The median total operative time was 90 min and blood loss 50 mL with no postoperative transfusions required. The median hospital stay was 1 day. No intra- or postoperative complications were documented. Continence status was unaffected, no patient required urinary pads. Postoperative pathology confirmed SV invasion in all specimens. Surgical margins were positive in seven (41%) patients. All patients had at least one positive imaging study, although three (18%) mp-MRI and five (29%) PET/CT assessments were negative. One (6%) pre-SVE biopsy was also negative but with positive imaging. Salvage SVE failure, defined as three consecutive PSA rises or the need for further treatment, occurred in six patients of whom three had a positive margin. Overall failure-free survival rates were 86%, 67%, and 53% at 1, 2, and 3 years after SVE, respectively. CONCLUSIONS: Salvage RA-SVE appears to be a safe focal treatment, with very low morbidity, for patients with localised SV recurrence after LDR-PB. It permits deferral of androgen deprivation therapy in selected patients. Bilateral SVE is mandatory. This surgical option should be considered in patients with isolated prostate cancer recurrence to the SV.

Dietary glycotoxins induce RAGE and VEGF up-regulation in the retina of normal rats.

Exogenous intake of glycotoxins present in western diet accelerates the accumulation of advanced glycation end products (AGEs) in multiple organs leading to potential tissue damage. Advanced ageing and diabetic conditions have been associated with AGEs deposition in multiple eye compartments including Bruch's membrane, optic nerve, lens and cornea. However, the impact of dietary AGEs in ocular physiology has not been extensively studied. The present study investigates the direct effects of a high AGE content diet in the ocular tissues of normal rats of different age. Two groups of baby (4 weeks of age) and adult (12 weeks of age) female Wistar rats (n = 73) were allocated to high- or low-AGE diet for 3 months. Upon completion of experimental protocol, somatometric, hormonal and biochemical parameters were evaluated in all groups. Circulating and tissue AGE levels were estimated along with their signaling receptor (receptor for AGEs, RAGE) and vascular endothelial growth factor A (VEGF-A) expression in ocular tissues of the different subgroups. High AGE intake was associated with elevated serum AGEs (p = 0.0001), fructosamine (p = 0.0004) and CRP levels (p = 0.0001) compared to low AGE. High peripheral AGE levels were positively correlated with significant increased tissue immunoreactivity of AGEs and RAGE in retinal and uveal tissues as well as retinal VEGF-A expression. Up-regulation of RAGE and VEGF-A expression was observed in the ocular tissue of both baby and adult animals fed with high-AGE diet. Co-localization of AGEs and RAGE staining was observed mainly in the inner retinal layers and the retinal pigment epithelium (RPE) of all groups. VEGF-A expression was elevated in the RPE, the inner nuclear layer and the retinal ganglion cell layer of the animals exposed to high-AGE diet. In conclusion, dietary AGEs intake affects the physiology of ocular tissues by up-regulating RAGE and VEGF-A expression contributing to enhanced inflammatory responses and pathologic neovascularization in normal organisms independent of ageing.

Newer therapies and surgical management of ketamine-induced uropathy: A review.

BACKGROUND AND AIMS: Ketamine use as a recreational drug is becoming more popular nowadays. Ketamine-induced uropathy (KIU) is a late finding observed with long-term use of ketamine. A systematic review of Ketamine-Induced Uropathy was performed to emphasise its key clinical manifestations, mechanism of action and establish an effective treatment pathway. METHODS AND RESULTS: A literature search was conducted in MEDLINE via Pubmed and Cochrane using the keywords ketamine and bladder, ketamine and uropathy, and ketamine and epidemiology. The search strategy was limited to articles published from 2000 to 2023. Both animal and human studies were included. A total of 101 papers were reviewed based on topic relevance from the title and abstracts available. While ketamine is a controlled drug in the United Kingdom (UK) and other countries, 283 ketamine-related deaths have been reported in the UK. There is no definite pathogenesis but multiple potential mechanisms that cause KIU and its related symptoms. KIU involves chronic inflammation of the bladder, ureteral wall thickening, hydronephrosis and finally, chronic renal failure. A multidisciplinary approach is paramount when managing these patients to break the vicious cycle. The mainstay of medical and surgical treatment pathways is continued abstinence to prevent symptom relapse. This review included the pathophysiology, novel medical treatments and surgical management of KIU. CONCLUSION: KIU is a rare but significantly disabling condition often seen among ketamine abusers. With the rising trend in drug addiction, KIU is expected to be more common. Unfortunately, it is a late complication in chronic ketamine abusers and is only partially reversible even with abstinence. This review discusses this rare entity's newer medical treatments and surgical options.

Predictors of biochemical recurrence after robot-assisted radical prostatectomy: single-centre analysis.

Introduction: We evaluated risk factors for biochemical recurrence (BCR) after robot-assisted radical prostatectomy (RARP) based on our department database. Material and methods: Patients who underwent RARP between 2018 and 2020 were identified and included in our retrospective study. Patients who received neoadjuvant treatment, patients with positive lymph nodes, salvage prostatectomies, and patients with missing data were excluded. BCR was defined as PSA ≥0.2 ng/ml. Parameters that were investigated were the International Society of Urological Pathologists (ISUP) score, stage, and positive surgical margins (PSM) as they were reported in the pathology report. A subgroup analysis based on the tumour stage was performed. Results: A total of 414 patients were included in the analysis. Seventy-seven of them experienced BCR. Based on multivariable analysis, ISUP grade was a strong predictor for BCR with odds ratio (OR): 2.86 (CI: 1.49-5.65; p = 0.002), OR: 5.90 (CI: 1.81-18.6; p = 0.003), OR: 4.63 (CI: 1.79-11.9; p = 0.001) for ISUP grade 3, 4, 5, respectively. Regarding tumour stage, pT2 and pT3a did not show any significant difference in predicting BCR (p = 0.11), whereas pT3b stage was a predictor for BCR with OR: 6.2 (CI: 2.25-17.7; p < 0.001). In the subgroup analysis for 206 patients with pT2 disease, ISUP group and PSM were predictors for BCR. On the other hand, when patients with pT3 disease were inspected, the only parameter that was predictive of BCR was pT3b disease (OR: 4.68, CI: 1.71-13.6; p = 0.003). ISUP grade, the extent of T3 disease, and the extent and ISUP grade of surgical margins were not predictors of BCR. Conclusions: The most important risk factors for BCR after RARP are ISUP grade and tumour stage. In pT2 disease, PSM is a significant predictor of BCR, along with high ISUP grade. The substage pT3b can be considered a predictor of BCR in pT3 cases.

Comparison of efficacy and satisfaction profile, between penile prosthesis implantation and oral PDE5 inhibitor tadalafil therapy, in men with nerve-sparing radical prostatectomy erectile dysfunction.

UNLABELLED: WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: Erectile dysfunction after nerve-sparing radical retropubic prostatectomy constitutes a challenge to the urologist. The mainstay of medical treatment after radical prostatectomy to restore spontaneous erectile function remains phosphodiesterase (PDE5) inhibitors, despite the fact that data from animal studies suggesting that PDE5 inhibitors can prevent smooth muscle apoptosis and fibrosis have not yet been extrapolated to humans because of a lack of standardized protocols. If the above treatment fails, second-line therapies such as intraurethral prostaglandins, penile injection therapy and vacuum devices are offered. When less invasive therapies are ineffective, interventions that preserve sexual function such as penile prosthesis implantation become the treatment of choice. Our study reveals the alternative of penile prosthesis implantation as first-line treatment in erectile dysfunction after nerve-sparing radical prostatectomy. It also highlights its superiority to the oral PDE5 inhibitor treatment, regarding the erection, frequency, firmness, maintenance and penetration ability. This suggests that a concept of an early penile intervention in the future would be promising for those patients who wish to remain sexually active without depending on oral formulations with doubtful and delayed results. OBJECTIVE: To evaluate the outcome of penile prosthesis surgery in comparison to oral phosphodiesterase type 5 (PDE5) inhibitor administration, in men with erectile dysfunction after nerve-sparing radical prostatectomy, as early penile intervention therapy. PATIENTS AND METHODS: A total of 174 patients treated by nerve-sparing retropubic radical prostatectomy (RRP) for clinically localized prostate cancer, between January 2006 and September 2009 enrolled in the study, 153 patients fulfilled the inclusion criteria, and 69 (45%) patients presented with post-RRP erectile dysfunction 6 months after primary surgery. Fifty-four patients were disease-free and subdivided into two arms according to treatment modality, either tadalafil three times/week or penile prosthesis implantation. All patients were evaluated using the International Index of Erectile Function (IIEF) questionnaire preoperatively and at 6, 12 and 24 month postoperatively. Repeated measurements analysis of variance was conducted to evaluate the effect of time and group on IIEF total score. RESULTS: There was a significant reduction in IIEF score from preoperative values to the first measurement after surgery in both treatment groups. The overall degree of change from the first time point immediately after surgery to 2 years was greater in the penile prosthesis group than the tadalafil group (20.4 ± 1.3 vs 8.1 ± 2.4, P < 0.001). CONCLUSIONS: The efficacy and satisfaction results of both treatment types are considered acceptable. However, regarding the erection frequency, firmness, penetration ability, maintenance and erection confidence it seems that penile prosthesis implantation is superior to oral treatment. The concept of early penile intervention should be considered and is promising for all patients with post-RRP erectile dysfunction.

Urinary Bladder Diverticulum: A Single-Center Experience in the Management of Refractory Lower Urinary Symptoms Using a Robotic Platform.

Introduction Urinary bladder diverticulum (UBD) is commonly seen in urological practice and, in most cases, does not need treatment specifically directed towards it. However, it can give rise to symptoms that are not distinct from this finding. This makes the evaluation and management of this complex patient group challenging. We present our experience with robotic bladder diverticulectomy (RBD) for acquired bladder diverticulum to assess the outcomes and safety of this procedure when patient symptoms have failed to respond to either medical or surgical treatment directed at other associated contributing factors. Methods We retrospectively collected data on all patients who underwent RBD for persistent lower urinary tract symptoms (LUTS) at Royal Surrey County Hospital, Guildford, between 2016 and 2021, including baseline characteristics, urodynamic findings, intraoperative and postoperative outcomes, and a six-month follow-up. Patients who were diagnosed with cancer in the diverticulum, associated pathology that may contribute to their symptoms, or who had concomitant procedures at the time of RBD were excluded from this study. Results We had six patients who underwent RBD; the median age and body mass index (BMI) were 63.8 years (range 48-73) and 27.1 kg/m2 (range 24-32), respectively. The most common presenting symptoms were refractory LUTS and recurrent urinary tract infections (UTIs). The urodynamic evaluation revealed varying findings like bladder outlet obstruction (BOO), poor compliance, and equivocal readings in these patients. All patients reported incomplete bladder emptying and double voiding, with half practicing clean intermittent self-catheterization (CISC). Diverticulum size averaged 9.4 cm (range 8.5-12). The median operative time and blood loss were 166 mins (range 150-180) and 75 mls (range 50-100), respectively. The average length of stay was 1.6 days (range 1-3). Three patients developed UTIs within a month after surgery, requiring a course of oral antibiotics. Post-void residual (PVR) measured an average of 32.6 mls (range 0-161) postoperatively compared to a preoperative average of 249 mls (range 125-400), showing a two-tailed p-value of 0.016. The International Prostate Symptom Score (IPSS) score for these patients showed an average of 27.83 (range 24-31) preoperatively compared to the postoperative average of eight (range 7-12), showing a two-tailed p-value of 0.0001. Final histology showed no malignancy, and all patients reported symptom improvement, with none requiring CISC after surgery. Conclusion RBD is a safe and effective procedure in carefully selected patients with refractory LUTS and UTIs showing good postoperative and functional outcomes. The presence of a large diverticulum can have a complex effect on bladder dynamics. In the era of robotic surgery and enhanced recovery, discussion about diverticulectomy should be encouraged after proper evaluation and counseling for patients who have failed to improve with other measures of treatment for their symptoms.

Functional and oncological outcomes of robot-assisted radical prostatectomy in obese men: a matched-pair analysis.

Robot-assisted radical prostatectomy (RARP) in men with body mass index (BMI) ≥ 35 kg/m2 is considered technically challenging. We conducted a retrospective matched-pair analysis to compare the oncological and functional outcomes of RARP in men with BMI ≥ 35 kg/m2. We interrogated our prospectively maintained RARP database and identified 1273 men who underwent RARP from January 2018 till June 2021. Among them, 43 had BMI ≥ 35 kg/m2, and 1230 had BMI < 35 kg/m2. A 1:1 genetic matching was performed between these two groups for PSA, Gleason grades, clinical stage, D'Amico risk stratification, and nerve-spare extent. Continence rates and biochemical rates on 1-year follow-up were analysed. We performed statistical analysis using SPSS, and Paired tests were done using Wilcoxon sign rank-sum test. p < 0.05 was considered statistically significant. The two groups were comparable in almost all parameters except for age. Console time (p = 0.20) and estimated blood loss (p > 0.90) were not significantly different. There was no blood transfusion, open conversion or (Clavien-Dindo grade ≥ 3) intra/postoperative complication in either of the two groups. The two groups did not have any difference in biochemical recurrence rates (BCR) on 1-year follow-up (p > 0.90). Men with BMI ≥ 35 achieved continence rates equivalent to men with BMI < 35 within 1 year. On logistic regression analysis, age (p < 0.001) and extent of nerve sparing (p = 0.026) emerged as significant factors influencing continence recovery. RARP is safe in men with BMI ≥ 35 kg/m2. The 1-year continence and oncological outcomes are similar to matched men with BMI < 35 kg/m2 undergoing RARP.

Self-removal of catheter after robot-assisted radical prostatectomy: a feasibility study.

Self-removal of urinary catheter as an option after robot-assisted radical prostatectomy (RARP) has never been explored in literature. We report the feasibility and outcome of the first study of this novel concept in our hospital. We conducted a prospective audit of self-TWOC (trial without catheter) in men who underwent consecutive RARP in our centre between April 2022 and September 2022. Men who had self-TWOC filled a questionnaire about the outcomes of self-TWOC. Carbon footprint and carbon offset for each hospital TWOC avoided were calculated. Of the 129 who underwent self-TWOC, 112 filled the questionnaire and were hence included in the final analysis. Self-TWOC was successful in all the 112 (100%) men in the study. 99.1% of men were satisfied with self-TWOC at home. We managed to avoid 79.6 ± 36.72 km of travel and 77 min of travel time for every self-TWOC. This also saved 85£/patient on clinic expenses and fuel cost savings of 9.87-15.99£ per patient depending on car engine size/type. The carbon footprint calculated was 20 kg CO2 assuming average engine sized diesel/petrol cars and 10 kg CO2 for an average UK petrol hybrid car. The calculated carbon offset per patient for diesel/petrol cars: 0.32£, petrol hybrid: 0.16£. Self-TWOC for 80-160 patients will save the carbon emissions equivalent to that of a passenger on a London-New York Trans-Atlantic flight. Self-TWOC is safe, affordable and is sustainable to the environment. Widespread acceptance of this practice change will be a small, but steady step towards greener health systems across the world.

The role of androgens in transgender medicine.

Androgen therapy is the mainstay of treatment in female to male (FtM) transgender persons to increase testosterone levels, suppress oestrogens and treat gender dysphoria. Testosterone is widely used for male hypogonadism, but is comparatively under-investigated in FtM transgender persons. The aim of our study was to identify treatment and safety outcomes associated with testosterone use in transgender medicine. Androgens in FtM transgender persons are effective to lower voice frequency, increase facial hair-growth, and increase hematocrit and hemoglobin levels to adult male reference ranges. A 1.2-fold-3.7-fold higher rate of myocardial infarction has been reported retrospectively, compared to cisgender women. Blood pressure, glycaemic control and body mass index remained unchanged in FtM transgender persons. Androgens in FtM transgender persons have important cardio-metabolic implications. Randomised control trials, longer follow-up periods and studies involving older persons may further improve the management of FtM transgender persons.

The impact of COVID-19 on surgical volume and surgical training at a high-volume pelvic oncology centre.

INTRODUCTION: The coronavirus (COVID-19) pandemic has overwhelmed most health services. As a result, many surgeries have been deferred and diagnoses delayed. The aim of this study was to assess the effect of the COVID-19 pandemic at a high-volume pelvic oncology centre. METHODS: A retrospective review was performed of clinical activity from 2017 to 2020. We compared caseload for index procedures 2017-2019 (period 1) versus 2020 (period 2) to see the effect of the COVID pandemic. We then compared the activity during the first lockdown (March 23rd) to the rest of the year when we increased our theatre access by utilising a 'clean' site. RESULTS: The average annual number of robotic assisted radical cystectomy (RARC) and robotic assisted radical prostatectomy (RARP) performed during period 1 was 82 and 352 respectively. This reduced to 68 (17.1% reduction) and 262 (25.6% reduction) during period 2. The number of patients who underwent prostate brachytherapy decreased from 308 to 243 (21% reduction). The number of prostate biopsies decreased from 420 to 234 (44.3% reduction). The number of radical orchidectomies decreased from 18 to 11 (39% reduction). The mean number of RARC and RARP per month during period 2 was 5.5 and 22. This decreased to 4 and 9 per month during the first national lockdown but was maintained thereafter despite two further lockdowns. CONCLUSION: There has been a substantial decrease in urological oncology caseload during the COVID pandemic. The use of alternate pathways such as 'clean' sites can ensure continuity of care for cancer surgery and training needs.

Patient Satisfaction and Regret After Robot-assisted Radical Prostatectomy: A Decision Regret Analysis.

OBJECTIVE: To assess treatment satisfaction and decision regret post robot-assisted radical prostatectomy (RARP) and correlate these with clinical, demographic and quality of life indicators. Our study took place at a high-volume United Kingdom center and patients were assessed at a minimum of 18 months postsurgery. METHODS: Patients who underwent RARP between June 2011 and May 2016 were invited to participate through mailed questionnaires. A total of 207 patients formed our cohort. The questionnaires included European Organization for Research and Treatment of Cancer Quality of Life of Cancer patients 30 and PR25 modules, sexual health inventory in men and Likert decisional regret scale. A Decisional Regret Scale score of >15 was used to define an outcome of high decision regret. RESULTS: The mean patient age was 63 years and the mean duration of follow up was 36 months. Of the 106 responders, 51 (48%) were fully satisfied with the decision to undergo RARP and 32 (30%) recorded high regret. The mean Decisional Regret Scale score was 11.3. High decision regret associated with the length of time from RARP to questionnaire administration, higher prostate specific quality of life symptom scores and lower sexual and erectile function scores. CONCLUSION: Our study represents the first contemporary United Kingdom series assessing decision regret following the management of localised prostate cancer with RARP. Higher regret was seen in one third of patients and was associated with worse disease-specific quality of life, sexual and erectile function measures. To minimize regret, collaborative and detailed discussion should take place pre-operatively when counselling patients about RARP. The potential longevity and impact on quality of life of these side effects should be made clear.

Robotic-assisted bladder diverticulectomy: point of technique to identify the diverticulum.

We aim to outline our technique of performing a robotic-assisted bladder diverticulectomy at our institution and report our surgical outcomes. We report the cases of three robotic-assisted bladder diverticulectomies, performed at the Royal Surrey County Hospital during the period of January 2014 to December 2015. Patient was positioned in low dorsal lithotomy position. A 6Fr double-J stent was prophylactically inserted at the start of the procedure. Foley catheter was placed over guide wire into the diverticulum and balloon inflated on the diverticulum neck. We used a transperitoneal extravesical approach to mobilise the distended bladder diverticulum, dissected en bloc and transected at the diverticulum neck in all cases. The bladder was closed in two layers with absorbable sutures. The procedures were uneventful, without post-operative complications and minimal blood loss. The median length of stay was 3 days and all three patients reported a significant improvement in all symptoms with non-significant post-void residuals. Robotic-assisted bladder diverticulectomy is a safe and effective procedure that results in both symptom relief and minimal post-void residuals.

Association of depressive symptoms with coagulation factors in young healthy individuals.

BACKGROUND: Depression has been reported to be an independent risk factor for coronary heart disease (CHD). We investigated the association of depressive symptoms with lipids and coagulation factors in young individuals free of CHD. METHODS: We recruited 1073 young healthy individuals candidates for military academies (mean age=18.4+/-0.8 years, males 762) in whom the presence of depressive symptoms was assessed by using the depression scale of Minnesota Multiphasic Personality Inventory test. Total cholesterol, triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, lipoprotein (a), fibrinogen, factors VII, VIII and X were measured. RESULTS: The depression score ranged from 22 to 90. The participants were divided into quartiles according to the depression score. Three hundred twenty-two subjects were classified in the upper quartile (score>48) and 269 in the lower quartile (score<37) of the depression score. Factor VII (102.95+/-24 versus 98.5+/-20%) and X levels (92+/-11 versus 89.7+/-10%) were significantly higher in individuals in the upper quartile compared to the lower quartile of the depression score. In a logistic regression model with factor VII as dependent variable (upper versus lower quartile) and depression score, age, gender, body mass index, exercise and smoking as predictor variables, depression was an independent predictor of factor VII levels with an adjusted odds ratio for high levels of factor VII of 1.05 (95% confidence interval 1.008-1.09, p=0.01). Factor VII levels were associated with triglycerides (r=0.21, p=0.001) while factor X with triglycerides (r=0.22, p<0.001) and cholesterol levels (r=0.12, p<0.001). CONCLUSIONS: Depressed mood is associated with a hypercoagulant profile as it is expressed by the higher levels of coagulation factors VII and X. This might partially explain the higher propensity for CHD of people with depressive symptoms.

Impact of diet-induced obesity in male mouse reproductive system: The role of advanced glycation end product-receptor for advanced glycation end product axis.

Obesity represents a route to broad physiological dysfunction affecting major organs including male urogenital system. Hyperglycemia, hyperlipidemia, and oxidative stress associated with obesity augment the formation of reactive metabolic by-products, namely advanced glycation end products (AGEs), leading to increased tissue deposition and damage. The exogenous intake and the endogenous accumulation of AGEs contribute to metabolic and reproductive abnormalities in both women and men. The present study assessed the effects of a diet high in saturated fatty acids (SAFA) on the lipid and metabolic profile (AGE levels, oxidative stress) as well as pathogenic (AGE, receptor for AGEs [RAGE] expression, apoptosis) and morphometric parameters of male reproductive system in vivo. Effects of switching to a diet rich in monounsaturated fatty acids (MUFA) or equal in the proportion MUFA to SAFA were further investigated. SAFA-fed animals were characterized by increased serum lipid concentrations (p < .05) compared to controls, but AGEs and peroxide levels were not significantly different across the different experimental groups. Elevated AGE deposition was detected for the first time in germ cells with a higher staining intensity in animals on the SAFA diet, compared to MUFA or MUFA-SAFA-fed animals or the control samples (p = .018). In Leydig cells, AGE localization was higher in the entire cohort of high-fat-fed animals compared to controls (p < .05). High-fat-fed mice displayed enhanced apoptosis compared to controls (p < .005). Furthermore, prostatic tissue demonstrated reduction in epithelial folding, an effect which was significantly reversed after MUFA diet administration. Our findings provide the basis for further investigation of AGE-RAGE axis in testicular and prostatic disturbances associated with diet-induced obesity. Simple dietetic intervention has beneficial effects on metabolic dysfunction of reproductive system before overt manifestations, indicating glycation as a promising therapeutic target.
