PURPOSE
Postoperative length of stay (LOS) after robot-assisted radical prostatectomy (RARP) is a potentially modifiable aspect of prostate cancer care. Our objective was to evaluate the use of same-day discharge (SDD) RARP and compare pre- and perioperative characteristics of these men with those who underwent hospitalization postoperatively.
MATERIALS AND METHODS
Perioperative outcomes for patients undergoing RARP were evaluated from the Michigan Urological Surgery Improvement Collaborative (MUSIC) registry. Men were classified by hospital LOS: SDD, 1 day, and 2 days. Practice and surgeon-level variation of SDD and the change in SDD use over time were assessed. The primary outcome was 30-day readmission after RARP.
RESULTS
We identified 10,249 men undergoing RARP in MUSIC from 2018 to 2022. Most patients had 1-day LOS (79.6%), with 2.8% undergoing SDD. The proportion of patients undergoing RARPs with SDD rose from 0.6% in 2018 to 1.2% in 2019 and 4.4% for 2020 to 2022. At least one SDD was performed in 12 of 28 MUSIC practices (42.9%) and by 52 of 138 urologists (37.7%). In multivariable analysis, odds of 30-day readmission were not significantly different between patients undergoing SDD and LOS 1 day (OR: 1.72, 95% CI: 0.92-3.22, = .090). Limitations include retrospective, registry-based observational study with nonuniform utilization of SDD.
CONCLUSIONS
Although more patients have undergone SDD after RARP beginning in 2018, rates across Michigan have remained < 5% annually. Importantly, patients undergoing SDD RARP did not experience significantly more readmissions compared to hospitalized patients. SDD appears safe and feasible for select patients who are motivated by this approach.

Holmium enucleation of the prostate (HoLEP) is a gold-standard, size-independent surgical treatment for benign prostatic hyperplasia (BPH) distinguished for its efficacy in tissue removal, shorter catheterization durations, lower transfusion rates, and decreased hospital stays when compared to transurethral resection of the prostate (TURP). The objective of this article is to demonstrate the step-by-step procedure of holmium laser cystolitholapaxy and enucleation of the prostate for BPH, emphasizing a top-down modified two-lobe technique with early apical release which enhances visualization and irrigation flow during the enucleation process.

Comparative Study
BACKGROUND
The delineation of intraprostatic lesions is vital for correct delivery of focal radiotherapy boost in patients with prostate cancer (PC). Errors in the delineation could translate into reduced tumour control and potentially increase the side effects. The purpose of this study is to compare PET-based delineation methods with histopathology.
MATERIALS AND METHODS
The study population consisted of 15 patients with confirmed high-risk PC intended for prostatectomy. [68Ga]-PSMA-PET/MR was performed prior to surgery. Prostate lesions identified in histopathology were transferred to the in vivo [68Ga]-PSMA-PET/MR coordinate system. Four radiation oncologists manually delineated intraprostatic lesions based on PET data. Various semi-automatic segmentation methods were employed, including absolute and relative thresholds, adaptive threshold, and multi-level Otsu threshold.
RESULTS
The gross tumour volumes (GTVs) delineated by the oncologists showed a moderate level of interobserver agreement with Dice similarity coefficient (DSC) of 0.68. In comparison with histopathology, manual delineations exhibited the highest median DSC and the lowest false discovery rate (FDR) among all approaches. Among semi-automatic approaches, GTVs generated using standardized uptake value (SUV) thresholds above 4 (SUV > 4) demonstrated the highest median DSC (0.41), with 0.51 median lesion coverage ratio, FDR of 0.66 and the 95th percentile of the Hausdorff distance (HD95%) of 8.22 mm.
INTERPRETATION
Manual delineations showed a moderate level of interobserver agreement. Compared to histopathology, manual delineations and SUV > 4 exhibited the highest DSC and the lowest HD95% values. The methods that resulted in a high lesion coverage were associated with a large overestimation of the size of the lesions.

Study Protocol for a Randomized Controlled Trial of Low Intensity Shockwave Therapy for the Treatment of Post-Radical Prostatectomy Erectile Dysfunction: "SHARP-ED TRIAL".
INTRODUCTION
Erectile Dysfunction (ED) is a common challenge post Radical Prostatectomy (RALP), affecting men's sexual health after undergoing definitive cancer therapy. Despite employing nerve-sparing techniques, ED remains a prevalent issue in this population. Studies indicate that approximately 70%-85% of men experience varying degrees of ED following RALP. The existing treatment landscape for post-RALP-ED presents limitations, and a discernible knowledge gap persists. To address this, our study aims to investigate the efficacy of Shockwave Therapy (SWT) as a potential intervention for managing ED after RALP.
METHODS
This prospective, randomized, sham-controlled clinical trial aims to recruit 189 eligible patients post-RP and assess the effects of SWT. Comprehensive screening, including medical history, physical examinations, and biochemical evaluations, will be conducted to confirm eligibility. The intervention involves utilizing a device to administer focal shockwaves targeted at cavernosal tissue. Safety measures include continuous monitoring for adverse events and rigorous reporting protocols. The primary endpoint assesses changes in participants' ability to engage in penetrative intercourse from baseline to study completion, while secondary endpoints encompass various measures of erectile function, including questionnaire-based assessments, ultrasound parameters, and clinical outcomes.
RESULTS
Statistical analysis, encompassing ANOVA for continuous variables and Fisher's exact test for categorical ones, will evaluate demographic characteristics, baseline data, and primary as well as secondary outcomes for statistical significance. Detailed analysis of trends, subgroup comparisons, and treatment effects will provide a comprehensive understanding of the impact of SWT on post-RP ED.
CONCLUSION
This study protocol represents a rigorous investigation into the potential therapeutic role of SWT in managing post-RP ED. The outcomes from this study aim to contribute valuable insights into the efficacy, safety, and potential improvements in erectile function following SWT, providing significant guidance for future interventions aimed at addressing this challenging condition affecting men's health and quality of life.

OBJECTIVE
The incidence of recurrent hernia after radical resection of prostate cancer is high, so this article discusses the incidence and risk factors of inguinal hernia after radical resection of prostate cancer.
METHODS
This case control study was conducted in The First People's Hospital of Huzhou clinical data of 251 cases underwent radical resection of prostate cancer in this hospital from March 2019 to May 2021 were retrospectively analyzed. According to the occurrence of inguinal hernia, the subjects were divided into study group and control group, and the clinical data of each group were statistically analyzed, Multivariate Logistic analysis was performed to find independent influencing factors for predicting the occurrence of inguinal hernia. The Kaplan-Meier survival curve was drawn according to the occurrence and time of inguinal hernia.
RESULTS
The overall incidence of inguinal hernia after prostate cancer surgery was 14.7% (37/251), and the mean time was 8.58 ± 4.12 months. The average time of inguinal hernia in patients who received lymph node dissection was 7.61 ± 4.05 (month), and that in patients who did not receive lymph node dissection was 9.16 ± 4.15 (month), and there was no significant difference between them (P > 0.05). There were no statistically significant differences in the incidence of inguinal hernia with age, BMI, hypertension, diabetes, PSA, previous abdominal operations and operative approach (P > 0.05), but there were statistically significant differences with surgical method and pelvic lymph node dissection (P < 0.05). The incidence of pelvic lymph node dissection in the inguinal hernia group was 24.3% (14/57), which was significantly higher than that in the control group 11.8% (23/194). Logistic regression analysis showed that pelvic lymph node dissection was a risk factor for inguinal hernia after prostate cancer surgery (OR = 0.413, 95%Cl: 0.196-0.869, P = 0.02). Kaplan-Meier survival curve showed that the rate of inguinal hernia in the group receiving pelvic lymph node dissection was significantly higher than that in the control group (P < 0.05).
CONCLUSION
Pelvic lymph node dissection is a risk factor for inguinal hernia after radical resection of prostate cancer.

PURPOSE
Transurethral resection of the prostate (TURP) is one of the surgical options for treating enlarged prostates with lower urinary symptoms (LUTS). In this older group of patients, concomitant prostate cancer is not uncommon. However, the fibrosis and distortion of the prostate anatomy by prior TURP can potentially hinder surgical efficacy at robotic-assisted radical prostatectomy (RARP). We aim to evaluate functional, and oncologic outcomes of RARP in patients with and without previous TURP.
METHODS
231 men with previous TURP underwent RARP (TURP group). These men were propensity score matched using clinicopathological characteristics to men without previous TURP who underwent RARP (Control group). Perioperative and postoperative variables were analysed for significant differences in outcomes between groups. Variables analysed included estimated blood loss (EBL), operative time, catheter time, hospitalization time, postoperative complications, positive surgical margins (PSM) rates, cancer status, biochemical recurrence (BCR), potency, and continence rates.
RESULTS
Patients in the TURP group showed no statistically significant differences in operative safety measures including median EBL, operative time, catheter time, hospitalization time or postoperative complications. No significant difference between the groups in terms of potency rates and continence rates. Furthermore, there were no statistically significant differences in oncological outcomes, including PSM rates (15% vs 18%, P = 0.3) and BCR.
CONCLUSION
In RARP after TURP there is often noticeable distortion of the surgical anatomy. For an experienced team the procedure is safe and provides similar oncologic control and functional outcomes to RARP in patients without previous TURP.

Meta-Analysis Review
A systematic review and meta-analysis of the role of perineal hydrodissection in perioperative, oncologic, and functional outcomes for patients undergoing robot-assisted radical prostatectomy.
This study aims to compare the perioperative, oncological, and functional outcomes of perineal hydrodissection (HD) with standard treatment (ST) in patients undergoing robot-assisted radical prostatectomy. We performed an exhaustive search in databases such as PubMed, Embase, Web of Science, and the Cochrane Library, seeking English-language studies relevant to our research question, with a cutoff date of April 2024. The pooled results were assessed using the weighted mean differences (WMDs), standardized mean differences (SMDs), and odds ratios (ORs) metrics. We also performed a sensitivity analysis. The meta-analysis was conducted utilizing Stata/MP version 18 software. The study was registered with PROSPERO (ID: CRD 42024536400). We included a total of five studies (three RCTs and two retrospective studies). According to the data from the Meta-analysis, the HD group showed positive effects in promoting urinary continence (OR 2.64, 95% CI 1.36, 5.12; p = 0.004 < 0.05) and erectile function (SMD 0.92, 95%CI 0.56, 1.27; p < 0.05) within 3 months after surgery. However, no notable disparities were observed in terms of operative time, estimated blood loss, bilateral nerve-sparing rate, or the rate of positive surgical margin. Perineal hydrodissection can be safely applied in robot-assisted radical prostatectomy (RARP), offering a distinct advantage in functional outcomes compared to those who undergo standard robot-assisted prostatectomy alone.

BACKGROUND
This study analyzed the risk factors associated with positive surgical margins (PSM) and five-year survival after prostate cancer resection to construct a positive margin prediction model.
METHODS
We retrospectively analyzed the clinical data of 148 patients treated with prostatectomy. The patients were divided into PSM group and Negative surgical margins (NSM) group. Several parameters were compared between the groups. All patients were followed up for 60 months. The risk factors for PSM and five-year survival were evaluated by univariate analysis, followed by multifactorial dichotomous logistic regression analysis. Finally, ROC curves were plotted for the risk factors to establish a predictive model for PSM after prostate cancer resection.
RESULTS
(1) Serum PSA, percentage of positive puncture stitches, clinical stage, surgical approach, Gleason score on puncture biopsy, and perineural invasion were significantly associated with the risk of PSM (P < 0.05). Serum PSA, perineural invasion, Gleason score on puncture biopsy, and percentage of positive puncture stitches were independent risk factors for PSM. (2) Total prostate-specific antigen (tPSA) by puncture, nutritional status, lymph node metastasis, bone metastasis, and seminal vesicle invasion may be risk factors for five-year survival. Lymph node metastasis and nutritional status were the main risk factors for the five-year survival of patients with prostate cancer. (3) After plotting the ROC curve, the area under the curve (AUC) [AUC: 0.776, 95%, confidence interval (CI): 0.725 to 0.854] was found to be a valid predictor of PSM; the AUC [AUC: 0.664, 95%, confidence interval (CI): 0.576 to 0.753] was also a valid predictor of five-year survival (P < 0.05). (4) The scoring system had a standard error of 0.02 and a cut-off value of 6. It predicted PSM after prostate cancer resection with moderate efficacy.
CONCLUSIONS
Serum PSA, perineural invasion, puncture biopsy Gleason score, and percentage of positive puncture stitches were independent risk factors for positive surgical margins (PSM). Also, lymph node metastasis and nutritional status were the main risk factors for the five-year survival of patients with prostate cancer. Overall, the prediction efficacy of this scoring system concerning the risk of PSM after prostate cancer resection was moderate.
