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.

Improved early and late continence following robot-assisted radical prostatectomy with concurrent bladder neck fascial sling (RoboSling).

Objective: To describe a novel RoboSling technique performed at the time of robot-assisted radical prostatectomy (RARP) and its utility for enhancing urinary function recovery postoperatively. Materials and Methods: The surgical technique involves harvesting a vascularised, fascial flap from the peritoneum on the posterior aspect of the bladder. Following completion of prostatectomy, the autologous flap is tunnelled underneath the bladder and incorporated into the rectourethralis and vertical longitudinal detrusor fibres at the posterior bladder neck with a modified Rocco suture. After urethra-vesical anastomosis is completed, the corners of the flap are hitched up to Cooper's ligament bilaterally with V-Loc sutures, tensioned and secured creating a bladder neck sling. A prospective, longitudinal cohort study was performed of 193 consecutive patients undergoing RARP between December 2016 and September 2019. The first 163 patients underwent standard RARP, and the last 30 patients had the RoboSling technique performed concurrently. Continence outcomes were the primary outcomes assessed using pad number and Expanded Prostate Cancer Composite (EPIC)-urinary domain questionnaire. Operative time (OT), estimated blood loss (EBL), complications and oncological outcomes were secondary outcomes. Results: The two groups were comparable for demographics and clinicopathological variables. At 3 months, zero pad usage (p = 0.005) and continence rates, defined as EPIC score ≥ 85 (p = 0.007), were both higher in the RoboSling group. EBL, complication rate and positive surgical margin rate did not differ between the two groups. Superior zero pad usage was observed at 1 year in the RoboSling group (p = 0.029). The RoboSling technique added on average 16 min to OT. Conclusions: The RoboSling procedure at the time of RARP was associated with earlier return to continence without negatively impacting other postoperative outcomes. This improvement in continence outcomes was maintained long term.

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.

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.

Robotic-assisted radical prostatectomy-impact of a mentorship program on oncological outcomes during the learning curve.

BACKGROUND AND AIMS: The learning curve for robotic-assisted radical prostatectomy (RARP) is estimated to be about 50-200 cases. This study will evaluate the benefit of a mentorship programme after completing a mini-fellowship in RARP by an experienced surgeon who previously trained in open and laparoscopic surgery. METHODS: Our study was a retrospective comparative analysis of RARP performed by a single consultant urologist. A retrospective chart review of the first 120 cases was performed. The 120 patients were divided into three groups of 40 cases. For the first 40 cases, an appropriately qualified mentor was present. The peri-operative and oncological outcomes were compared between the three groups. RESULTS: Operative times significantly decreased with experience (250 min vs 234 min vs 225 min, p < 0.05). Complication rates, estimated blood loss, and length of stay were similar between all groups. There was a higher rate of positive margins in the final group (20% vs 17.5% vs 32.5%, p < 0.5). There was a greater number of pT3 tumours in group 3 (42%, n = 17) compared to groups 1 and 2 (20%, n = 8, and 22.5%, n = 9) which may account for the higher rate of positive margins in this group. CONCLUSION: In the transition of an experienced laparoscopic surgeon to robotic surgery, we showed that there is a benefit of a mentorship programme after a mini-fellowship in reducing the impact of the learning curve on patient outcomes. Ongoing mentorship may be of benefit in cases where a high volume of tumour is suspected and should be avoided in the early part of the learning curve to maximise oncological outcomes.

Spermatic vein embolization as a treatment for symptomatic varicocele.

INTRODUCTION: Varicocele is a relatively common condition in men that causes pain in approximately 10% of cases. There have been few studies to date assessing the improvements in both pain and quality of life parameters associated with spermatic vein embolization (SVE) as a treatment for patients with symptomatic varicocele, so we aimed to assess this. METHODS: A review was carried out of consecutive SVE procedures performed at our institution from 2013-2019. Only patients with painful varicocele were included after other causes of testicular pain were excluded. The technique employed was a combination of distal coil embolization of the spermatic vein with 4-6 mm coils at the level of the inguinal canal, as well as sclerotherapy to prevent reflux of sclerosant. Furthermore, a prospective validated Pain Impact Questionnaire-6 (PIQ-6) was performed to assess for improvement in quality of life. A matched pair Student two-tailed t-test was used to compare mean scores pre- and post-treatment, with 95% confidence intervals presented as T scores and their associated p-values. RESULTS: Over six years, 62 SVE procedures were performed for symptomatic varicocele. Success rate was 95%, with a median followup of nine months. Two patients had a failed procedure on two occasions requiring subsequent surgical ligation. There was one clinically significant recurrence. All components of PIQ-6 score showed a statistically significant reduction post-SVE, most noticeably pain severity and impact on leisure activities. CONCLUSIONS: SVE is a safe, effective, and well-tolerated treatment for symptomatic varicocele, improving pain and quality of life.

Prostate cancer detection with magnetic resonance imaging (MRI)/ cognitive fusion biopsy: Comparing standard and targeted prostate biopsy with final prostatectomy histology.

INTRODUCTION: The use of multiparametric magnetic resonance imaging (MRI) with targeted biopsies of the prostate improves the diagnosis of clinically significant prostate cancer. Recent studies have shown that targeted prostate biopsies also more accurately predict final histopathology after radical prostatectomy (RP). There are three broad techniques for performing MRI-targeted prostate biopsy: cognitive MRI/ultrasound (US) fusion, software MRI/US fusion, and in-bore MRI-guided. Current practices recommend that a standard systematic 12-core prostate biopsy be performed, as well as targeted biopsies in patients with positive MRI findings. This study aimed to evaluate the accuracy of histological grading of cognitive MRI/US fusion prostate biopsy by comparing the histology from the targeted biopsy specimens (TB), standard systematic specimens (SB), and the combination of both (CB) specimens with the final histological grade from subsequent prostatectomy. METHODS: A retrospective, single-center review of 115 patients who underwent standard systematic and cognitive MRI/US-targeted biopsy of the prostate before undergoing a RP between 2016 and 2019 was performed. MRI findings, biopsy, final histology International Society of Urological Pathology (ISUP) grades, and patient demographics were collected. Cochran's Q test and McNemar test were used to compare the differences in upgrading, downgrading, and concordance between each biopsy group. RESULTS: The concordance between SB, TB, and CB biopsy were 28.7%, 49.6%, and 50.4%, respectively. There was no significant difference in concordance between TB and CB. Patients were more likely to be downgraded on the final histology when comparing CB with TB alone (26.1% vs. 16.5%, p<0.05). In cases where an ISUP grade 1 cancer was diagnosed on TB (n=24), there was a 62.5% chance that the final histology would be upgraded. In the same sample, when combined with a SB, the risk of upgrading on final histology was reduced to 37.5%. CONCLUSIONS: Although grading concordance between TB and CB were similar, the concomitant use of a SB significantly reduced the rate of upgrading in the final RP histopathology. CB may result in better decision-making regarding treatment options and also have implications for intraoperative planning.

Admission of patients with acute urinary retention leads to a definitive management decision.

BACKGROUND: Acute urinary retention (AUR) is a common urologic emergency. However, its management is not standardized due to lack of clinical guidelines. AIMS: We retrospectively reviewed the treatment of all male patients admitted to our institution with AUR over 12 months. METHODS: Data was obtained from the HIPE (Hospital Inpatient Enquiry) data system, each patient's electronic discharge summary and from patient medical records. RESULTS: There were 130 AUR admissions during the period. About 74 admissions were due to benign prostatic enlargement (BPE). Of these, 45.9% (n = 34) passed their trial without catheter (TWOC). The remainder (n = 40) failed their TWOC necessitating recatheterization and consideration for transurethral resection of prostate (TURP) or re-TWOC. An indwelling urinary catheter (IDC) was inserted for 27.5% (n = 11) of patients with a failed TWOC secondary to comorbidities. This group had a mean age of 78 years (range 68-96 years). Of those who failed their TWOC, 32.5% (n = 13) had a TURP on index admission. Of the remaining 16 patients with failed TWOC, 75% (n = 12) were discharged with an IDC and readmitted for an elective TURP with a median waiting time of 55 days (range 17-138 days). 18.75% (n = 3) passed a re-TWOC and thus offset the need to have any surgical intervention and 6.25% (n = 1) proceeded to a radical retropubic prostatectomy for biopsy proven prostate adenocarcinoma. CONCLUSION: Admission of patients with acute urinary retention leads to a definitive management decision and reduced prolonged catheterization.

Laparoscopic and hand-assisted laparoscopic donor nephrectomy: A systematic review and meta-analysis.

OBJECTIVE: To compare the perioperative outcomes of hand-assisted laparoscopic donor nephrectomy (HALDN) and pure LDN, as HALDN and LDN are the two most widely used techniques of DN to treat end-stage renal disease. METHODS: In this systematic review and meta-analysis, we performed a literature search of PubMed, Embase, Web of Science, and Cochrane from 01/01/1995 to 31/12/2014. The primary outcome was conversion to an open procedure. Secondary outcomes were warm ischaemia time (WIT), operation time (OT), estimated blood loss (EBL), complications, and length of stay (LOS). Data analysed were presented as odds ratios (ORs) or weighted mean differences (WMDs) with 95% confidence intervals (CIs), I2, and P values. Subgroup analysis was performed. RESULTS: There were 24 studies included in the meta-analysis; three randomised controlled trials (RCTs), one randomised pilot study, two prospective, and 18 retrospective cohort studies. There were no differences in conversion to an open procedure between the two techniques for both RCTs (OR 0.42, 95% CI 0.06, 2.90; I2 = 0%, P < 0.001) and cohort studies (OR 1.06, 95% CI 0.63, 1.78; I2 = 0%, P = 0.84). WIT was shorter for the HALDN (-41.79 s, 95% CI -71.85, -11.74; I2 = 96%, P = 0.006), as was the OT (-26.32 min, 95% CI -40.67, -11.97; I2 = 95%, P < 0.001). There was no statistically significant difference in EBL, complications or LOS. CONCLUSION: There is little statistical evidence to recommend one technique. HALDN is associated with a shorter WIT and OT. LDN has equal safety to HALDN. Further studies are required.
