ABSTRACT

Robotic-assisted laparoscopic prostatectomy (RALP) is the surgical standard of care for patients with localized prostate cancer. Although uncommon, the procedure involves a potential risk of injury to adjacent anatomical structures. We report on a unique case of iatrogenic ureteral injury during RALP that required subsequent robotic-assisted laparoscopic ureteral reimplantation for definitive repair. A 57-year-old male underwent RALP using the Da Vinci Xi system (Intuitive Surgical, Sunnyvale, CA). The procedure was unremarkable and a 20 French Foley catheter was placed with plans for removal after one week following a negative cystogram. On postoperative day two, his creatinine level elevated to 2.69 mg/dL from a baseline of 1.40 mg/dL, left-sided flank pain increased, and non-contrast CT imaging revealed moderate left proximal hydroureteronephrosis and no other abnormalities. Aside from mild nausea on postoperative day one, he had no other symptoms. An integrated stent was unable to be placed by urology at this time. Subsequently, a left percutaneous nephrostomy tube was placed under fluoroscopic guidance. After this intervention, the patient's symptoms improved and the decision was made not to proceed with operative re-exploration at this time to attempt identification of the obstruction. Three weeks later, the patient underwent cystoscopy with attempted left retrograde ureteropyelography and left ureteroscopy due to suspected distal obstruction. This revealed complete obstruction of the intramural portion of the ureter, presumed to be secondary to suture ligation at the time of the vesicourethral anastomosis. Seven weeks postoperatively, the patient underwent robotic-assisted laparoscopic left ureteral reimplantation. Thereafter, the patient had a resolution of his left hydroureteronephrosis and acute kidney injury. This case describes an intravesical ureteral ligation during RALP. An iatrogenic intravesical ureteral ligation has far less guiding literature than a more common ureteral transection. Additionally, ureteral transection is often identified and managed intraoperatively, while the ureteral ligation presented in this case is far less likely to be apparent during surgery. Early identification will allow for rapid reoperation to manage the injury. We hypothesize that during the vesicourethral anastomosis, the left intramural ureter was ligated. Importantly, with the use of a 3-0 V-Loc stitch for the vesicourethral anastomosis, its barbed nature would not facilitate simple surgical removal. In conclusion, when performing RALP, the depth of the bladder-sided vesicourethral anastomotic stitch should be carefully considered to avoid a similar injury.

ABSTRACT

INTRODUCTION: Urinary incontinence (UI), especially stress UI, is common after prostatectomy. Penile compression devices (PCDs) may be a safe, tolerable option for conservative management in men who are not candidates for or not interested in surgical intervention for their UI. AREAS COVERED: This article examines the epidemiology of post-prostatectomy urinary incontinence (PPI), and options for management. All available studies on PCDs are explored, including those on biomechanics, safety, tolerability, and user experience. History, availability of PCDs, and areas for future development are discussed. EXPERT OPINION: PCDs are an option for conservative management of PPI. They are recommended for those men without impairment in cognition, dexterity, or sensation. They should be worn for short periods of time and are best used during situations when incontinence might be precipitated. Overall, data suggest they are well tolerated and effective when tested, but large randomized comparative trials and studies of long-term use with relevant patient reported outcome measures are lacking. More studies are needed on commercially available PCDs. Biomechanical studies suggest that there are superior designs and materials both for efficacy and tolerability. With an aging population, and more older men going for prostate surgery, a larger market for these devices is likely.

ABSTRACT

The purpose of this study is to evaluate whether the periprostatic adipose tissue thickness (PPATT) is an independent prognostic factor for prostate cancer patients after laparoscopic radical prostatectomy (LRP). This retrospective cohort study included consecutive prostate cancer patients who underwent LRP treatment at Wuhan Union Hospital from June 2, 2016, to September 7, 2023. PPATT was defined as the thickness of periprostatic fat and was obtained by measuring the shortest vertical distance from the pubic symphysis to the prostate on the midsagittal T2-weighted MR images. Subcutaneous adipose tissue thickness (SATT) was obtained by measuring the shortest vertical distance from the pubic symphysis to the skin at the same slice with PPATT. The primary outcome of the study was biochemical recurrence (BCR), and the secondary outcome was overall survival (OS). Multivariable Cox regression analysis was used to identify independent prognostic factors for prostate cancer survival and prognosis. Based on the optimal cutoff value, 162 patients were divided into a low PPATT/SATT group (n = 82) and a high PPATT/SATT group (n = 80). During the entire follow-up period (median 23.5 months), 26 patients in the high PPATT/SATT group experienced BCR (32.5%), compared to 18 in the low PPATT/SATT group (22.0%). Kaplan-Meier curve analysis indicated that the interval to BCR was significantly shorter in the high PPATT/SATT group (P = 0.037). Multivariable Cox regression analysis revealed that an increase in the PPATT/SATT ratio was associated with BCR (hazard ratio: 1.90, 95% CI, 1.03-3.51; P = 0.040). The PPATT/SATT ratio is a significant independent risk factor for BCR after LRP for prostate cancer patients.

ABSTRACT

INTRODUCTION: Most men diagnosed with very-low and low-risk prostate cancer are candidates for active surveillance; however, there is still a misclassification risk. We examined whether PI-RADS category 4 or 5 combined with ISUP 1 on prostate biopsy predicts upgrading and/or adverse pathology at radical prostatectomy. MATERIALS AND METHODS: A total of 127 patients had ISUP 1 cancer on biopsy after multiparametric MRI (mpMRI) and then underwent radical prostatectomy. We then evaluated them for ISUP upgrading and/or adverse pathology on radical prostatectomy. RESULTS: Eight-nine patients (70%) were diagnosed with PI-RADS 4 or 5 lesions. ISUP upgrading was significantly higher among patients with PI-RADS 4-5 lesions (84%) compared to patients with equivocal or non-suspicious mpMRI findings (26%, p < 0.001). Both PI-RADS 4-5 lesions (OR 24.3, 95% CI 7.3, 80.5, p < 0.001) and stage T2 on DRE (OR 5.9, 95% CI 1.2, 29.4, p = 0.03) were independent predictors of upgrading on multivariate logistic regression analysis. Men with PI-RADS 4-5 lesions also had significantly more extra-prostatic extension (51% vs. 3%, p < 0.001) and positive surgical margins (16% vs. 3%. p = 0.03). The only independent predictor of adverse pathology was PI-RADS 4-5 (OR 21.7, 95% CI 4.8, 99, p < 0.001). CONCLUSION: PI-RADS 4 or 5 lesions on mpMRI were strong independent predictors of upgrading and adverse pathology. Incorporating mpMRI findings when selecting patients for active surveillance must be further evaluated in future studies.

ABSTRACT

PURPOSE: We evaluated the feasibility, safety, and learning curve of extraperitoneal single-port robot-assisted radical prostatectomy (SP-RARP) and introduced innovative surgical techniques to maintain the instrument positions during the procedures. MATERIALS AND METHODS: A cohort of 100 patients underwent extraperitoneal SP-RARP at our institution from December 2021 to April 2023. The procedures were performed by an experienced urology surgeon utilizing two surgical techniques for dissecting the posterior aspect of the prostate-"changing instrument roles" and "using camera inversion"-to prevent positional shifts between the camera and instruments. RESULTS: The mean operation time for SP-RARP was 93.58 minutes, and the mean console time was 65.16 minutes. The mean estimated blood loss during the procedures was 109.30 mL. No cases necessitated conversion to multi-port robot, laparoscopy, or open surgery, and there were no major complications during the hospital stay or in the short-term follow-up. Early outcomes of post-radical prostatectomy indicated a biochemical recurrence rate of 4.0% over a mean follow-up duration of 6.40 months, with continence and potency recovery rates of 92.3% and 55.8%, respectively. Analysis of the learning curve showed no significant differences in operation time, console time, and positive surgical margin rates between the initial and latter 50 cases. CONCLUSIONS: Extraperitoneal SP-RARP is a feasible and safe option for the treatment of localized prostate cancer in skilled hands. Continued accrual of cases is essential for future comparisons of SP-RARP with multiport approaches.

ABSTRACT

PURPOSE: This study aims to prospectively analyze the effects of anticholinergic therapy using imidafenacin on detrusor overactivity occurring after robot-assisted radical prostatectomy (RARP). MATERIALS AND METHODS: Patients were followed-up at outpatient visits 2-4 weeks post-surgery (visit 2) to confirm the presence of urinary incontinence. Those confirmed with urinary incontinence were randomly assigned in a 1:1 ratio to the anticholinergic medication group (imidafenacin 0.1 mg twice daily) or the control group. Patients were followed-up at 1, 3, and 6 months post-surgery for observational assessments, including the International Prostate Symptom Score (IPSS) and Overactive Bladder Symptom Score (OABSS). RESULTS: A total of 49 patients (25 in the treatment group and 24 in the control group) were randomized for the study. There were no differences observed between the groups in terms of age, comorbidities, prostate size, or pathological staging. According to the IPSS questionnaire results, there was no statistically significant difference between the medication and control groups (p=0.161). However, when comparing storage and voiding symptoms separately, there was a statistically significant improvement in storage symptom scores (p=0.012). OABSS also revealed statistically significant improvement in symptoms from 3 months post-surgery (p=0.005), which persisted until 6 months post-surgery (IPSS storage: p=0.023, OABSS: p=0.013). CONCLUSIONS: In the case of urinary incontinence that occurs after RARP, even if the function of the intrinsic sphincter is sufficiently preserved, if urinary incontinence persists due to changes in the bladder, pharmacological therapy using imidafenacin can be beneficial in managing urinary incontinence.

ABSTRACT

BACKGROUND AND OBJECTIVE: The landscape of surgical training is undergoing transformative changes, especially in the realm of robot-assisted procedures like radical prostatectomy (RARP). This narrative review explores the evolving methodologies and innovations in RARP training, emphasizing the shift from traditional training approaches, such as the Halsted method, to more scientific methods like proficiency-based progression (PBP). The rationale for the review stems from the increased adoption of robot-assisted surgery and the resulting increase in associated adverse events reported in the United States. The Patient Safety in Robotic Surgery (SAFROS) project initiated by the European Commission of the World Health Organization emphasized the importance of structured training programs for robotic surgeons. However, the review points out the limited availability of standardized curricula for RARP training, leading to non-homogeneous training worldwide. METHODS: PubMed was searched primarily for the following topics: training AND robotic AND prostatectomy; robotic training AND prostatectomy AND learning; simulator AND robotic AND prostatectomy. Literature was selected based on historical significance and landmark studies as well as publications published after 2000. References from select studies were additionally included. KEY CONTENT AND FINDINGS: The advent of robotic surgery, especially in RARP, demands unique skills necessitating specialized training. The review delves into the diverse stages of robotic surgery training, starting with e-learning and progressing through virtual reality simulators, dry and wet laboratories, culminating in modular console training. Each training stage plays a critical role, addressing the challenges posed by new technologies and tools. CONCLUSIONS: The ever-evolving landscape of surgical training underscores the critical need for globally standardized, effective, and accessible programs. PBP emerges as a promising methodology, and technological advancements open new possibilities for telementoring via platforms like 5G. This review emphasizes the imperative to equip surgeons with the requisite skills for intricate procedures like RARP, addressing current challenges while anticipating the future developments in this dynamic field.

ABSTRACT

BACKGROUND: Robotic-assisted radical prostatectomy (RARP) is currently a first-line treatment option for men with localized prostate cancer (PCa), at least 10 years of life expectancy, and candidate for curative treatment. We performed a scoping review to evaluate the role of artificial intelligence (AI) on RARP for PCa. METHODS: A comprehensive literature search was performed using EMBASE, PubMed, and Scopus. Only English papers were accepted. The PICOS (Patient Intervention Comparison Outcome Study type) model was used; P: adult men with PCa undergoing RARP; I: use of AI; C: none; O: preoperative planning improvement and postoperative outcomes; S: prospective and retrospective studies. RESULTS: Seventeen papers were included, dealing with prediction of positive surgical margins/extraprostatic extension, biochemical recurrence, patient's outcomes, intraoperative superimposition of magnetic resonance images to identify and locate lesions for nerve-sparing surgery, identification and labeling of surgical steps, and quality of surgery. All studies found improving outcomes in procedures employing AI. CONCLUSIONS: The integration of AI in RARP represents a transformative advancement in surgical practice, augmenting surgical precision, enhancing decision-making processes and facilitating personalized patient care. This holds immense potential to improve surgical outcomes and teaching, and mitigate complications. This should be balanced against the current costs of implementation of robotic platforms with such a technology.

ABSTRACT

Background/Aim: To examine the specific time frame and identify associated risk factors from commencement of hormonal therapy to the onset of castration-resistant prostate cancer among patients who have developed biochemical recurrence following radical prostatectomy. Patients and Methods: We retrospectively reviewed the records of 92 patients who developed biochemical recurrence and received hormonal therapy as initial salvage treatment after radical prostatectomy for high-risk localized prostate cancer from 2005 to 2021. The castration-resistant prostate cancer-free survival rates from the commencement of salvage hormonal therapy were analyzed using log-rank methods. Cox proportional hazard regression was performed to analyze the risk factors associated with acquiring castration resistance. The patients were stratified based on those risk factors. Results: During a median follow-up duration of 57 months, 24 (26.1%) patients developed castration-resistant prostate cancer. The 5- and 10-year castration-resistant prostate cancer-free survival rates were 73.6% and 54.5%, respectively. A multivariate analysis showed that Grade Group of 5 and prostate-specific antigen doubling time at biochemical recurrence of ≤3 months were independent predictors of castration-resistant prostate cancer. The 5-year castration-resistant prostate cancer-free survival rates in the low- and high-risk groups, stratified according to the aforementioned factors, were 85.4% and 47.6%, respectively. Conclusion: Patients in high Grade Group and short prostate-specific antigen doubling time after radical prostatectomy are more likely to develop resistance to salvage hormonal therapy.

ABSTRACT

Background and objective: A positive surgical margin (PSM) occurs in up to 32% of patients undergoing robot-assisted radical prostatectomy (RARP). Diffuse reflectance spectroscopy (DRS), which measures tissue composition according to its optical properties, can potentially be used for real-time PSM detection during RARP. Our objective was to assess the feasibility of DRS in distinguishing prostate cancer from benign tissue in RARP specimens. Methods: In a single-center prospective study, DRS measurements were taken ex vivo for RARP specimens from 59 patients with biopsy-proven prostate carcinoma. Discriminating features from the DRS spectra were used to create a machine learning-based classification algorithm. The data were split patient-wise into training (70%) and testing (30%) sets, with ten iterations to ensure algorithm robustness. The average sensitivity, specificity, accuracy, and area under the receiver operating characteristic curve (AUC) from ten classification iterations were calculated. Key findings and limitations: We collected 542 DRS measurements, of which 53% were tumor and 47% were healthy-tissue measurements. Twenty discriminating features from the DRS spectra were used as the input for a support vector machine model. This model achieved average sensitivity of 89%, specificity of 82%, accuracy of 85%, and AUC of 0.91 for the test set. Limitations include the binary label input for classification. Conclusions and clinical implications: DRS can potentially discriminate prostate cancer from benign tissue. Before implementing the technique in clinical practice, further research is needed to assess its performance on heterogeneous tissue volumes and measurements from the prostate surface. Patient summary: We looked at the ability of a technique called diffuse reflectance spectroscopy to guide surgeons in discriminating prostate cancer tissue from benign prostate tissue in real time during prostate cancer surgery. Our study showed promising results in an experimental setting. Future research will focus on bringing this technique to clinical practice.

ABSTRACT

Background and objective: The role of pelvic lymph node dissection (PLND) for prostate cancer is still controversial. This study aims to compare the outcomes of PLND between extraperitoneal single-port (SP eRARP) and transperitoneal multiport (MP tRARP) robotic-assisted radical prostatectomy. Methods: This was a retrospective analysis from our single-center database for patients who underwent SP eRARP or MP tRARP with PLND between 2015 and 2023. The primary endpoint was to analyze and compare specific data related to PLND between the two populations by the detection of pN+ patients, the total number of lymph nodes removed, and the number of positive lymph nodes removed. The secondary endpoints included comparing major complications, lymphoceles, and biochemical recurrence between the two cohorts of the study. Key findings and limitations: A total of 293 patients were included, with 85 (29%) undergoing SP eRARP and 208 (71%) undergoing MP tRARP. SP eRARP showed significant differences in PLND extension from MP tRARP, while MP tRARP yielded more lymph nodes (p < 0.001). There were no differences in pN+ patient detection (p = 0.7) or the number of positive lymph nodes retrieved (p = 0.6). The rates of major complications (p = 0.6), lymphoceles (p = 0.2), and biochemical recurrence (p = 0.9) were similar between the two groups. Additionally, SP eRARP had shorter operative time (p = 0.045), hospital stay (p < 0.001), and less postoperative pain at discharge (p = 0.03). Limitations include a retrospective, single-center analysis. Conclusions and clinical implications: Despite the SP approach in RARP resulting in fewer retrieved lymph nodes, outcomes were comparable with the MP approach regarding the detection of patients with positive lymph nodes and the number of positive nodes. Additionally, the SP approach led to lower pain levels and shorter hospital stays. Patient summary: With this study, we demonstrate that pelvic lymph node dissection performed via the extraperitoneal approach during robotic-assisted radical prostatectomy with a single-port system provides comparable outcomes with the standard transperitoneal multiport approach in detecting patients with positive lymph nodes and retrieving positive nodes. In addition, it offers significantly reduced pain levels and shorter hospital stays.

ABSTRACT

BACKGROUND: Patients undergoing treatment for prostate cancer may develop lymphoedema of the midline region. This has a substantial impact on a patient's quality of life and its diagnosis is often delayed or missed. Therefore, the purpose of this study is to compare the characteristics of patients with leg and midline lymphoedema to patients with only leg lymphoedema. METHODS: We retrospectively collected patient-, cancer-, lymphoedema- and lymphoedema treatment-related data of 109 men with lymphoedema after treatment for prostate cancer. First, 42 characteristics were compared between both groups. Second, factors predicting presence of midline lymphoedema were explored by multivariable analyses. RESULTS: The mean age of the patients with lymphoedema was 68 ( ±7) years and mean BMI is 28 (±4) kg/m2. Median duration of lymphoedema before the first consultation was 27 (9;55) months. Based on univariable analyses, patients with leg and midline lymphoedema had more frequently upper leg lymphoedema (89% (31/35) vs. 69% (51/74), p = 0.026), skin fibrosis (34% (12/35) vs. 16% (12/74), p = 0.034) and lymphatic reconstructive surgery (9% (3/35) vs. 0% (0/71), p = 0.020) than patients with only leg lymphoedema. Additionally, patients with leg and midline lymphoedema reported less frequently lower leg lymphoedema (77% (27/35) vs. 95% (70/74), p = 0.007). Based on the multivariable analysis, not having lower leg lymphoedema, skin fibrosis, performing self-bandaging and self-manual lymphatic drainage appear to be predictors for having midline lymphoedema. CONCLUSIONS: If patients with lymphoedema after prostate cancer do not have lower leg lymphoedema, have skin fibrosis, perform self-bandaging or self-manual lymphatic drainage, they possibly have midline lymphoedema.

ABSTRACT

PURPOSE: One of the most frequent side effects of radical prostatectomy (RP) is urinary incontinence. The primary cause of urine incontinence is usually thought to be impaired urethral sphincter function; nevertheless, the pathophysiology and recovery process of urine incontinence remains unclear. This study aimed to identify potential risk variables, build a risk prediction tool that considers preoperative urodynamic findings, and direct doctors to take necessary action to reduce the likelihood of developing early urinary incontinence. METHODS: We retrospectively screened patients who underwent radical prostatectomy between January 1, 2020 and December 31, 2023 at the First People 's Hospital of Nantong, China. According to nomogram results, patients who developed incontinence within three months were classified as having early incontinence. The training group's general characteristics were first screened using univariate logistic analysis, and the LASSO method was applied for the best prediction. Multivariate logistic regression analysis was carried out to determine independent risk factors for early postoperative urine incontinence in the training group and to create nomograms that predict the likelihood of developing early urinary incontinence. The model was internally validated by computing the performance of the validation cohort. The nomogram discrimination, correction, and clinical usefulness were assessed using the c-index, receiver operating characteristic curve, correction plot, and clinical decision curve. RESULTS: The study involved 142 patients in all. Multivariate logistic regression analysis following RP found seven independent risk variables for early urinary incontinence. A nomogram was constructed based on these independent risk factors. The training and validation groups' c-indices showed that the model had high accuracy and stability. The calibration curve demonstrates that the corrective effect of the training and verification groups is perfect, and the area under the receiver operating characteristic curve indicates great identification capacity. Using a nomogram, the clinical net benefit was maximised within a probability threshold of 0.01-1, according to decision curve analysis (DCA). CONCLUSION: The nomogram model created in this study can offer a clear, personalised analysis of the risk of early urine incontinence following RP. It is highly discriminatory and accurate, and it can help create efficient preventative measures and identify high-risk populations.

ABSTRACT

INTRODUCTION:   Prostate cancer has a variable natural history and, despite the existence of biochemical recurrence (BCR) predictors, they are still limited in predicting outcomes.  The role of testosterone in advanced prostate cancer is well known, however its role in localized prostate cancer is still uncertain.  In the present study, we evaluated the relationship of testosterone levels and androgen receptor (AR) expression with oncological and functional outcomes, in patients undergoing radical retropubic prostatectomy (RRP). MATERIALS AND METHODS:   Through a retrospective study, patients who underwent RRP, who had at least two preoperative total testosterone dosages, were analyzed and compared according to testosterone levels, oncological and functional outcomes.  After analyzing data, tissue samples were selected in a biorepository to carry out the AR and the AR-V7 expression. RESULTS:   After applying exclusion criteria, 212 patients were included in the analysis.  Thirty-two patients (15.1%) had low testosterone levels and, in this group, a lower rates of erectile function recovery were observed at 24 months (53.1% vs. 71.7%; p = 0.037), a higher rate of BCR (21.9% vs. 9.4%; p = 0.041) and higher International Society of Urological Pathology (ISUP) grade in biopsy products.  The AR expression was higher in patients with low testosterone, but there was no difference in relapse rates. CONCLUSIONS:   Lower levels of testosterone were related to lower rates of erectile function recovery at the end of 24 months after RRP, in addition to conferring higher rates of BCR and higher ISUP grades in biopsy.  Furthermore, patients with total testosterone < 300 ng/dL had higher expression of AR, but no difference in BCR rates.

ABSTRACT

Background: Robot-assisted radical prostatectomy with intraoperative pelvic lymph node dissection is the criterion standard for surgical treatment of nonmetastatic intermediate- and high-risk prostate cancer. However, this method is associated with symptomatic lymphocele (SLC), which is an important morbidity factor. To overcome this complication, several modifications of the technique have been developed, including the peritoneal interposition flap (PIF). We performed an updated systematic review and meta-analysis to investigate the efficacy and safety of this technique for preventing SLC and lymphocele (LC) formation. Materials and methods: Searches were performed using databases and references from included studies and previous systematic reviews. Only randomized controlled trials and nonrandomized cohorts were included. Primary outcomes were the incidence of SLC and LC formation, and safety outcomes were defined as operation time, estimated blood loss, length of hospital stay, and urinary incontinence. Quality assessment was performed using the Newcastle-Ottawa Scale and Cochrane Collaboration's tool. Pooled treatment effects were estimated using odds ratios with 95% confidence intervals (CIs) for binary endpoints. Heterogeneity was examined using Cochran's Q test and I 2 statistics; p values < 0.10 and I 2 > 25% were considered significant for heterogeneity. We used Mantel-Haenszel fixed-effect models in the analyses with low heterogeneity. Otherwise, the DerSimonian and Laird random-effects model was used. Results: The initial search yielded 510 results. After the removal of duplicate records and application of the exclusion criterion, 9 studies were fully reviewed for eligibility. Three randomized controlled trials and 5 retrospective cohorts met all the inclusion criteria, comprising 2261 patients, of whom 1073 (47.4%) underwent PIF. Six studies reported a significant reduction in SLC in the PIF group, and 3 of the 4 studies reported LC formation yielded significant results in preventing this complication. The incidence of SLC and LC formation in a follow-up of ≥3 months was significantly different between the PIF and no PIF group (odds ratio, 0.34 [95% CI, 0.16­0.74; p = 0.006] and 0.48 [95% CI, 0.31­0.74; p = 0.0008]), respectively. The safety outcomes did not differ significantly between the 2 groups. Conclusions: These results suggest that PIF is an effective and safe technique for preventing LC and SLC in patients undergoing transperitoneal robot-assisted radical prostatectomy and pelvic lymph node dissection.

ABSTRACT

We present the case of a 75 year old transgender woman 18 months post gender-affirming vaginoplasty found to have unfavorable, intermediate risk prostate cancer. She elected a robotic radical prostatectomy with bilateral pelvic lymph node dissection. Postoperatively, the patient resumed neovaginal dilation without difficulty, and had improvements on International Prostate Symptom Score when compared to post-vaginoplasty, pre-prostatectomy. Incontinence measured by Revised Urinary Incontinence Scale remained mild. Robotic prostatectomy can, under appropriate circumstances, allow preservation of the neovaginal vault, but requires considerable experience and multidisciplinary intraoperative collaboration.

ABSTRACT

Background and aims: To evaluate the quality of life in patients treated for prostate cancer in detail, an accessible, extensive, and easy-to-administer questionnaire is needed. The self-administered 50-item "Expanded Prostate Cancer Index Composite" (EPIC) is an instrument used for this purpose, but it is not officially translated into Romanian. The aim of the study was to translate and validate the Romanian version of the EPIC. Methods: We translated and culturally adapted the EPIC into Romanian. For validation, we included a retrospective analysis of 112 patients who underwent robotic radical prostatectomy and a prospective study including 120 consecutive patients hospitalized before surgical treatment. Baseline and follow-up assessments took place before and at six months, two, and five years post-surgery, between January 2014 and December 2015. We performed cross-sectional correlations between the EPIC, AUASI, and SF-12 at baseline, factor analysis, and calculated the internal consistency. Results: For most EPIC domains and subscales, our a priori-defined criteria for reliability were fulfilled (Cronbach's alpha 0.7-0.9). Cross-sectional correlations between EPIC scales and AUASI domain ranged from 0.23-0.69, and SF-12 domains ranged from 0.21-0.53 and 0.22-0.61, respectively. The retrospective analysis showed a medium acceptability and understanding of the EPIC questionnaire. In the prospective study, the revised EPIC draft showed an overall higher acceptability with a responding rate of 66% at a 5-year follow-up. All domains exhibited good internal consistency except for the hormonal section (Cronbach's α = 0.67) at the 6-month follow-up. Conclusion: The Romanian version of the EPIC is reliable, responsive and valid for measuring HRQL in prostate cancer patients. The EPIC questionnaire proved to be an exhaustive and reproducible instrument for evaluating the quality of life in Romanian prostate cancer patients.

ABSTRACT

Intraoperative frozen section (IFS) is used with the intention to improve functional and oncological outcomes for patients undergoing radical prostatectomy (RP). High resource requirements of IFS techniques such as NeuroSAFE may preclude widespread adoption, even if there are benefits to patients. Recent advances in fresh-tissue microscopic digital imaging technologies may offer an attractive alternative, and there is a growing body of evidence regarding these technologies. In this narrative review, we discuss some of the familiar limitations of IFS and compare these to the attractive counterpoints of modern digital imaging technologies such as the speed and ease of image generation, the locality of equipment within (or near) the operating room, the ability to maintain tissue integrity, and digital transfer of images. Confocal laser microscopy (CLM) is the modality most frequently reported in the literature for margin assessment during RP. We discuss several imitations and obstacles to widespread dissemination of digital imaging technologies. Among these, we consider how the 'en-face' margin perspective will challenge urologists and pathologists to understand afresh the meaning of positive margin significance. As a part of this, discussions on how to describe, categorize, react to, and evaluate these technologies are needed to improve patient outcomes. Limitations of this review include its narrative structure and that the evidence base in this field is relatively immature but developing at pace.

ABSTRACT

OBJECTIVE: The occurrence of prostate hyperplasia has increased remarkedly, especially in elderly patients; However, research on which surgical treatment is effective and safe for benign prostatic hyperplasia (BPH) in elderly people over 70 years old is limited. This study aimed to investigate the clinical efficacy and safety of transurethral plasma kinetic prostatectomy (TUPKP) and holmium laser enucleation of prostate (HoLEP) as a therapy for benign prostatic hyperplasia (BPH) in the elderly. METHODS: A total of 148 patients with BPH admitted from December 2022 to December 2023 were chosen and divided into HoLEP (n = 74) and TUPKP (n = 74) groups according to the surgical operation. Perioperative related indexes, preoperative and postoperative international prostate symptom scores and life quality scores were compared between the two groups. The postoperative complications were also counted for the two groups. RESULTS: The HoLEP group had lower intraoperative bleeding, mean operative time, catheter indwelling time and hospital stays than the TUPKP group (p < 0.001). Before treatment, no significant difference in prostate symptom scores was found between the two groups (p > 0.05). After treatment, the prostate symptom scores in the HoLEP group were significantly lower than those in the TUPKP group (p < 0.001). However, the maximum urinary flow rate was significantly higher (p < 0.001) and the residual urine volume was significantly lower (p < 0.001) in the HoLEP group than in the TUPKP group after operation. The complication rate in the TUPKP group was 25.66%, which was significantly higher than the 9.46% in the HoLEP group (p < 0.05). The life quality scores of the HoLEP group were higher than those of the TUPKP group (p < 0.001). CONCLUSIONS: HoLEP for BPH therapy is effective and safe with low incidence of postoperative complications.

ABSTRACT

OBJECTIVE: This study aims to assess the effect of pelvic floor muscle exercise (PFME) on urinary incontinence after radical prostatectomy. METHODS: PubMed, Web of Science, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP and other domestic and foreign databases were searched for published literature until December 2023 on the effect of pelvic muscle exercise on urinary incontinence in patients after radical prostatectomy. The retrieved literatures were screened, and data were extracted. After evaluating the quality of the literatures, RevMan 5.4 software was used for meta-analysis. RESULTS: This work included nine articles consisting of 1208 sufferers with urinary incontinence after radical prostatectomy. The forest plot showed that patients in the experimental group had better postoperative outcomes at 1 month (Relative Risk (RR) = 3.38, 95% confidence interval (CI) (1.83; 6.25)), 3 months (RR = 1.99, 95% CI (1.67; 2.38)) and 6 months (RR = 1.34, 95% CI (1.20; 1.49)). The incidence of urinary incontinence was statistically significant compared with the control group (p < 0.05). Patients in the experimental group 12 months after surgery (RR = 1.13, 95% CI (0.99; 1.23)) showed no significant difference in the incidence of urinary incontinence compared with the control group (p > 0.05). CONCLUSIONS: PFME can significantly increase the recovery rate of urinary incontinence in sufferers with prostate cancer at 1, 3 and 6 months after radical surgery but have no significant improvement at 12 months. Urodynamic analysis may be needed for patients with long-term urinary incontinence.
