Nerve-sparing radical prostatectomy using the neurovascular structure-adjacent frozen-section examination (NeuroSAFE): results after 20 years of experience.

OBJECTIVES: To evaluate the long-term oncological outcomes and functional results of the neurovascular structure-adjacent frozen-section examination (NeuroSAFE) during nerve-sparing (NS) radical prostatectomy (RP). MATERIALS AND METHODS: A 10-yr survival analysis on 11069 RPs performed with or without the NeuroSAFE, between January 2002 to June 2011 was carried out. In the NeuroSAFE cohort, the neurovascular structure-adjacent prostatic margins are removed and stained for cryo-sectioning during RP. In case of a PSM, partial or full removal of the neurovascular bundle was performed. The impact of NeuroSAFE on biochemical recurrence-free survival (BFS), salvage radiation therapy-free survival, metastasis-free survival, and prostate cancer-specific survival at 10 years was analyzed. 1-year (1-yr) erectile function (EF), 1-yr, and 2-yr continence rates were assessed in propensity score-based matched cohorts. RESULTS: Median follow-up was 121 (IQR: 73, 156) months. No differences in BFS between NeuroSAFE and non-NeuroSAFE were recorded (10-yr BFS: NeuroSAFE vs non-Neurosafe, pT2: 81% vs 84%, p = 0.06; pT3a: 58% vs. 63%, p = 0.6; ≥pT3b: 22% vs. 27%, p = 0.99). No differences were found between the two groups in terms of sRFS (pT2: p = 0.1; pT3a: p = 0.4; ≥pT3b: p = 0.4) (Fig. 1B, Table 2), and MTS (pT2: p = 0.3; pT3a: p = 0.6; ≥pT3b: p = 0.9). The NeuroSAFE-navigated patients reported a better 1-yr EF than non-NeuroSAFE (68% vs. 58%, p = 0.02) and no differences in 1-yr and 2-yr continence rates (92.4% vs. 91.8%, and 93.4% vs. 93%, respectively). The main limitation is the retrospective study design. CONCLUSIONS: While the NeuroSAFE approach did not show significant improvements in long-term oncologic or continence outcomes, it did provide an opportunity for a higher proportion of patients to improve postoperative functional results, possibly through increased nerve-sparing procedures.

Biochemical Response of <0.1 ng/ml Predicts Therapy-free Survival of Prostate Cancer Patients following Prostate-specific Membrane Antigen-targeted Salvage Surgery.

BACKGROUND: In a subset of patients with oligorecurrent prostate cancer (PCa), salvage surgery with prostate-specific membrane antigen (PSMA) radioguided surgery (PSMA-RGS) seems to be of value. OBJECTIVE: To evaluate whether a lower level of postoperative prostate-specific antigen (PSA; <0.1 ng/ml) is predictive of therapy-free survival (TFS) following salvage PSMA-RGS. DESIGN, SETTING, AND PARTICIPANTS: This cohort study evaluated patients with biochemical recurrence after radical prostatectomy and oligorecurrent PCa on PSMA positron emission tomography treated with PSMA-RGS in three tertiary care centers (2014-2022). INTERVENTION: PSMA-RGS. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Postsalvage surgery PSA response was categorized as <0.1, 0.1-<0.2, or >0.2 ng/ml. Kaplan-Meier and multivariable Cox regression models evaluated TFS according to PSA response. RESULTS AND LIMITATIONS: Among 553 patients assessed, 522 (94%) had metastatic soft tissue lesions removed during PSMA-RGS. At 2-16 wk after PSMA-RGS, 192, 62, and 190 patients achieved PSA levels of <0.1, 0.1-<0.2, and >0.2 ng/ml, respectively. At 2 yr of follow-up, TFS rate was 81.1% versus 56.1% versus 43.1% (p < 0.001) for patients with PSA <0.1 versus 0.1-<0.2 versus >0.2 ng/ml. In multivariable analyses, PSA levels of 0.1-0.2 ng/ml (hazard ratio [HR]: 1.9, confidence interval [CI]: 1.1-3.1) and ≥0.2 ng/ml (HR: 3.2, CI: 2.2-4.6, p < 0.001) independently predicted the need for additional therapy after PSMA-RGS. The main limitation is the lack of a control group. CONCLUSIONS: For patients after salvage PSMA-RGS, a lower biochemical response (PSA <0.1 ng/ml) seems to predict longer TFS. This insight may help in counseling patients postoperatively as well as guiding the timely selection of additional therapy. PATIENT SUMMARY: We studied what happened to prostate cancer patients in three European centers who had salvage surgery using a special method called prostate-specific membrane antigen-targeted radioguidance. We found that patients who had low prostate-specific antigen levels soon after surgery were less likely to need further treatment for a longer time.

Video-Assisted Informed Consent in Endoscopic Urology: A Randomized Trial on Ureteroscopy.

Purpose: The aim of this study is to evaluate the possible benefits of using video consent in the preoperative ureteroscopy (URS) consent process. Material and Methods: Prospective randomized trials took place at two Italian tertiary-care centers from March 2022 to September 2022. Patients were randomly assigned to two groups: Group A (standard verbal/written informed consent) and Group B (informed consent supported by video). We investigated the impact of both types of informed consent on patient anxiety levels using the Spielberger State-Trait Anxiety Inventory (STAI) questionnaire both pre- and post-consent. In addition, using the Visual Analogue Scale, analysis of the effect of informed consent on postoperative pain and the number of calls for assistance during hospitalization as secondary outcomes was done. To assess the satisfaction level related to the whole process, patients were asked to rate their experience on a scale of 1-10, with 1 indicating "not satisfied" and 10 indicating "completely satisfied." Results: Overall, 166 patients were randomized 1:1 in each group. The multivariable regression model demonstrated that video-assisted informed consent significantly increased the difference between post- and pre-consent STAI with a reduced level of anxiety. The video-assisted informed consent significantly predicted the number of assistance calls during hospitalization. Conclusions: Video consent for ureteroscopies is a valid tool to improve procedure awareness and satisfaction. Video consent is able to reduce procedure-related patient anxiety and postoperative assistance calls, thus proving to be useful in obtaining better-informed consent for endourological procedures.

Limited prognostic role of routine serum markers (AP, CEA, LDH and NSE) in oligorecurrent prostate cancer patients undergoing PSMA-radioguided surgery.

INTRODUCTION: We evaluated the prognostic role of pre-salvage prostate-specific membrane antigen-radioguided surgery (PSMA-RGS) serum levels of alkaline phosphatase (AP), carcinoembryonic antigen (CEA), lactate dehydrogenase (LDH), and neuron-specific enolase (NSE). MATERIALS AND METHODS: Patients who consecutively underwent PSMA-RGS for prostate cancer (PCa) oligorecurrence between January 2019 and January 2022 were selected. Biomarkers were assessed one day before surgery. Cox regression and logistic regression models tested the relationship between biochemical recurrence-free survival (BFS), 6- and 12-month biochemical recurrence (BCR), and several independent variables, including biomarkers. RESULTS: 153 consecutive patients were analyzed. In the univariable Cox regression analysis, none of the biomarkers achieved predictor status (AP: hazard ratio [HR] = 1.03, 95% CI 0.99, 1.01; p = 0.19; CEA: HR = 1.73, 95% CI 0.94, 1.21; p = 0.34; LDH: HR = 1.01, 95% CI 1.00, 1.01; p = 0.05; NSE: HR = 1.02, 95% CI 0.98, 1.06; p = 0.39). The only independent predictor of BFS was the number of positive lesions on PSMA PET (HR = 1.17, 95% CI 1.02, 1.30; p = 0.03). The number of positive lesions was confirmed as independent predictor for BCR within 6 and 12 months (BCR < 6 months: odds ratio [OR] = 1.1, 95% CI 1.0, 1.3; p = 0.04; BCR < 12 months: OR = 1.1, 95% CI 1.0, 1.3; p = 0.04). CONCLUSION: The assessment of AP, CEA, LDH, and NSE before salvage PSMA-RGS showed no prognostic impact. Further studies are needed to identify possible predictors that will optimize patient selection for salvage PSMA-RGS.

Intraoperative image-guidance during robotic surgery: is there clinical evidence of enhanced patient outcomes?

BACKGROUND: To date, the benefit of image guidance during robot-assisted surgery (IGS) is an object of debate. The current study aims to address the quality of the contemporary body of literature concerning IGS in robotic surgery throughout different surgical specialties. METHODS: A systematic review of all English-language articles on IGS, from January 2013 to March 2023, was conducted using PubMed, Cochrane library's Central, EMBASE, MEDLINE, and Scopus databases. Comparative studies that tested performance of IGS vs control were included for the quantitative synthesis, which addressed outcomes analyzed in at least three studies: operative time, length of stay, blood loss, surgical margins, complications, number of nodal retrievals, metastatic nodes, ischemia time, and renal function loss. Bias-corrected ratio of means (ROM) and bias-corrected odds ratio (OR) compared continuous and dichotomous variables, respectively. Subgroup analyses according to guidance type (i.e., 3D virtual reality vs ultrasound vs near-infrared fluoresce) were performed. RESULTS: Twenty-nine studies, based on 11 surgical procedures of three specialties (general surgery, gynecology, urology), were included in the quantitative synthesis. IGS was associated with 12% reduction in length of stay (ROM 0.88; p = 0.03) and 13% reduction in blood loss (ROM 0.87; p = 0.03) but did not affect operative time (ROM 1.00; p = 0.9), or complications (OR 0.93; p = 0.4). IGS was associated with an estimated 44% increase in mean number of removed nodes (ROM 1.44; p < 0.001), and a significantly higher rate of metastatic nodal disease (OR 1.82; p < 0.001), as well as a significantly lower rate of positive surgical margins (OR 0.62; p < 0.001). In nephron sparing surgery, IGS significantly decreased renal function loss (ROM 0.37; p = 0.002). CONCLUSIONS: Robot-assisted surgery benefits from image guidance, especially in terms of pathologic outcomes, namely higher detection of metastatic nodes and lower surgical margins. Moreover, IGS enhances renal function preservation and lowers surgical blood loss.

PSA-density, DRE, and PI-RADS 5: potential surrogates for omitting biopsy?

OBJECTIVE: In contrast to other malignancies, histologic confirmation prior treatment in patients with a high suspicion of clinically significant prostate cancer (csPCA) is common. To analyze the impact of extracapsular extension (ECE), cT-stage defined by digital rectal examination (DRE), and PSA-density (PSA-D) on detection of csPCA in patients with at least one PI-RADS 5 lesion (hereinafter, "PI-RADS 5 patients"). MATERIALS AND METHODS: PI-RADS 5 patients who underwent MRI/Ultrasound fusion biopsy (Bx) between 2016 and 2020 were identified in our institutional database. Uni- and multivariable logistic-regression models were used to identify predictors of csPCA-detection (GGG ≥ 2). Risk models were adjusted for ECE, PSA-D, and cT-stage. Corresponding Receiver Operating Characteristic (ROC) curves and areas under the curve (AUC) were calculated. RESULTS: Among 493 consecutive PI-RADS 5 patients, the median age and PSA was 69 years (IQR 63-74) and 8.9 ng/ml (IQR 6.0-13.7), respectively. CsPCA (GGG ≥ 2) was detected in 405/493 (82%); 36/493 patients (7%) had no cancer. When tabulating for PSA-D of > 0.2 ng/ml/cc and > 0.5 ng/ml/cc, csPCA was found in 228/253 (90%, PI-RADS5 + PSA-D > 0.2 ng/ml/cc) and 54/54 (100%, PI-RADS5 + PSA-D > 0.5 ng/ml/cc). Finally, a model incorporating PSA-D and cT-stage achieved an AUC of 0.79 (CI 0.74-0.83). CONCLUSION: In PI-RADS 5 patients, PSA-D and cT-stage emerged as strong predictors of csPCA at biopsy. Moreover, when adding the threshold of PSA-D > 0,5 ng/ml/cc, all PI-RADS 5 patients were diagnosed with csPCA. Therefore, straight treatment for PCA can be considered, especially if risk-factors for biopsy-related complications such as obligatory dual platelet inhibition are present.

Robot-assisted vs open retropubic radical prostatectomy: a propensity score-matched comparative analysis based on 15 years and 18,805 patients.

PURPOSE: To compare oncological, functional, and surgical outcomes of a large cohort of patients who underwent open retropubic radical prostatectomy (ORP) or robot-assisted radical prostatectomy (RARP). MATERIALS AND METHODS: Data from 18,805 RPs performed with either the open or the robot-assisted approaches at a single tertiary referral center between 2008 and 2022 were analyzed. The impact of surgical approach on biochemical recurrence-free survival, salvage radiotherapy-free survival, and metastasis-free survival was analyzed by log-rank test and Kaplan-Meier analysis in a propensity score (PS)-based matched cohort. Intraoperative and postoperative surgical outcomes were assessed. One-week, 3-month, and 12-month continence rates and 12-month erectile function (EF) were analyzed. RESULTS: No statistically significant differences in oncological outcomes were found between ORP and RARP. A slight statistically significant difference in favor of RARP was noted in urinary continence at 3 months (RARP vs. ORP: 81% vs. 77%, p = 0.007) and 12 months (91% vs. 89.3%, p = 0.008), respectively. The rate of EF was statistically significantly higher (60%) after RARP than after ORP (45%, p < 0.001). CONCLUSION: Both RARP and ORP yielded similar oncological outcomes. RARP offered a slight advantage in terms of continence recovery, but its clinical significance may be less meaningful. RARP resulted in significantly improved postoperative EF, suggesting a potential influence of both surgical experience and minimally invasive approach.

Office-based management of Non-Muscle Invasive Bladder Cancer (NMIBC): A position paper on current state of the art and future perspectives.

To the Editor, Bladder cancer is one of the most common cancers in humans, representing the 7th and 17th type of neoplasm in both genders. Its incidence and mortality are quite heterogeneous in different countries and are due to different risk factors, quality and prevalence of healthcare and the possibility of early diagnosis and treatment of the tumor and its potential recurrences [...].

A randomized controlled study on acupuncture for peri-operative pain after open radical prostatectomy.

OBJECTIVES: To evaluate the advantages of adding acupuncture to standard postoperative pain management for open radical prostatectomy (RP). MATERIALS AND METHODS: A randomized controlled trial (1:1:1) comparing routine postoperative analgesic care (control [CON]) vs the addition of press tack needle acupuncture (ACU) or press tack placebo acupressure (SHAM) for pain management after open RP was performed. A total of 126 patients were enrolled between February 2020 and April 2021. After open RP, the CON group received standard postoperative analgesia, the ACU group received long-term acupuncture with press tacks at specific points (P-6, Shenmen and SP-6) along with standard analgesia, and the SHAM group received placebo press tacks at the same acupuncture points alongside standard analgesia. The primary endpoint was postoperative pain measured on a numeric rating scale, the NRS-11, calculated as the area under the curve. The cumulative use of routine postoperative analgesics, time to first defaecation, and quality of life were analysed using the Kruskal-Wallis rank sum test, Fisher's exact test, and Pearson's chi-squared test. RESULTS: The ACU group reported significantly less postoperative pain compared to the SHAM (P = 0.007) and CON groups (P = 0.02). There were no significant difference in median (interquartile range) cumulative pain medication usage, time to first defaecation (CON: 37 [33, 44] h; SHAM: 37 [33, 42] h; ACU: 37 [33, 41] h; P > 0.9), or health status at discharge (EuroQol five-dimension, five-level general health assessment questionnaire: CON: 70 [65-83]; SHAM: 70 [60-80]; ACU: 70 [50-80]). CONCLUSION: Incorporating acupuncture into postoperative pain management can improve patient postoperative outcomes.

Prostate-specific membrane antigen radioguided surgery with negative histopathology: an in-depth analysis.

PURPOSE: To identify reasons for negative histopathology of specimens from prostate-specific membrane antigen (PSMA) radioguided surgery (PSMA-RGS) in recurrent prostate cancer (PCa) after prostatectomy. METHODS: Of 302 patients who underwent PSMA-RGS, 17 (5.6%) demonstrated a negative histopathology. Preoperative data, PSMA PET, PSMA SPECT, and follow-up information were analyzed retrospectively to differentiate true/false positive (TP/FP) from true/false negative (TN/FN) lesions. RESULTS: The median prostate-specific antigen at PET was 0.4 ng/ml (interquartile range [IQR] 0.3-1.2). Twenty-five index lesions (median short axis 7 mm, IQR 5-8; median long-axis 12 mm, IQR 8-17) had a median SUVmax of 4 (IQR 2.6-6; median PSMA expression score 1, IQR 1-1). Six lesions were TP, twelve were FP, one was TN, and six remained unclear. All TP lesions were in the prostatic fossa or adjacent to the internal iliac arteries. Three suspected local recurrences were FP. All FP lymph nodes were located at the distal external iliac arteries or outside the pelvis. A low PSMA-expressing TN node was identified next to a common iliac artery. Unclear lesions were located next to the external iliac arteries or outside the pelvis. CONCLUSION: In most cases with a negative histopathology from PSMA-RGS, lesions were FP on PSMA PET. Unspecific uptake should be considered in low PSMA-expressing lymph nodes at the distal external iliac arteries or outside the pelvis, especially if no PSMA-positive lymph nodes closer to the prostatic fossa are evident. Rarely, true positive metastases were missed by surgery or histopathology.

PSMA PET-directed surgical metastasis-directed therapy in metachronous prostate cancer.

We present the case of a patient who underwent an open radical prostatectomy with pelvic lymph node dissection (Gleason 4+3, pT3a pN1 R0) in March 2017. In November 2020, prostate-specific membrane antigen (PSMA)-radioguided salvage lymph node dissection was planned due to a single left para-rectal lymph node at a [68Ga] Ga-PSMA-I&T PET. In January 2022, the [68Ga] Ga-PSMA-I&T PET showed an isolated liver lesion. Biopsy confirmed prostate adenocarcinoma. A liver segmentectomy was performed. A complete biochemical response was reported until the last follow-up (December 2022). Prostate-specific membrane antigen positron emission tomography (PSMA PET)-directed metastasis-directed therapy may be an effective treatment in selected cases, allowing a benefit in the oncological outcome.

Prevalence of bilateral loco-regional spread in unilateral pelvic PSMA PET positive recurrent prostate cancer.

BACKGROUND: Defining the best surgical template for salvage lymph node dissection (SLND) in patients exhibiting unilateral prostate cancer (PCa) recurrence in pelvic lymph nodes (LNs) is an unmet need. We assessed the risk of missing contralateral nodal recurrence in patients with unilateral positive PSMA-PET who were treated with bilateral PSMA-radioguided (RGS) SLND. METHODS: Patients who consecutively underwent bilateral PSMA-radioguided SLND for PCa recurrence between April 2014 and January 2023 were identified. We compared PSMA PET findings with the number and the location of PCa LN metastases of the final pathological report. Univariable logistic regression models to try to predict contralateral missed disease were performed. RESULTS: Sixty patients were identified. At PSMA-RGS, the median PSA level was 0.71 ng/mL (IQR: 0.38-2.28). At PSMA-PET pre-SLND, 49 (82%) patients had unilateral exclusively pelvic lesions, 2 (3%) had unilateral positive nodes at the level of the common iliac arteries, and 9 (15%) had unilateral positive nodes in both levels. Final pathology revealed unilateral LN involvement in 43 (72%), a negative report in 3 (5%), and bilateral positive lesions in 14 (23%) patients. In the univariable logistic regression models, none of the tested factors showed influence on missing contralateral lesions. Four patients out of 35 (11%) with one positive LN at PSMA-PET had bilateral PCa recurrence. CONCLUSIONS: Patients with one-sided positive LNs on PSMA PET can be considered for a unilateral PSMA-radioguided SLND template with the caveat that about a quarter of patients ultimately have bilateral positive LNs. Larger prospective randomized trials are needed to confirm our findings.

New minimally invasive solutions for Benign Prostatic Obstruction (BPO) management: A position paper from the UrOP (Urologi Ospedalità Gestione Privata).

To the Editor, In recent years, alternative solutions have been proposed to obtain effective results comparable to TURP, which is currently considered the gold standard, and laser vapo-enucleation techniques (1, 2), but with the possibility of maintaining sexual functions. In recent years there has been a growing trend towards ejaculation preservation. Although the results of TURP (3), and most laser enucleation techniques are undoubted in the Benign Prostatic Hyperplasia (BPH) and Lower Urinary Tract Symptoms (LUTS) management, they often lack in the preservation of ejaculation. All the alternative recently proposed interventions (Rezum, AquaBeam, Urolift, TPLA, i-TIND, LEST) are procedures considered by some authors to be promising in both managing BPO and preserving sexual functions. However, all these methods are limited by a lack of long-term follow-up that would evaluate the efficacy over time, possible complications related to the method and the correct patient selection for a specific method. The aim of this letter is to summarize the available evidence and provide clinicians with practical recommendations on the use of the brand new minimally invasive techniques for the management of BPO.

Comparative analysis of robot-assisted and open approach for PSMA-radioguided surgery in recurrent prostate cancer.

PURPOSE: To compare the oncological and surgical outcomes of patients with recurrent prostate cancer (PCa) who underwent either open or newly established robot-assisted salvage prostate-specific membrane antigen-radioguided surgery (PSMA-RGS). MATERIALS AND METHODS: Patients who consecutively underwent PSMA-RGS for PCa recurrence between January 2021 and December 2022 were identified. The rate of complete biochemical response, biochemical recurrence-free survival [BFS], and the rate of salvage therapy were evaluated. Univariable and multivariable regression models tested the association between the surgical approach and surgical outcomes. RESULTS: Overall, 85 patients were selected, with 61 patients (72%) undergoing open PSMA-RGS and 24 patients (28%) receiving a robot-assisted approach. The oncological outcomes of the two groups were comparable (12-month BFS: 41% (Confidence interval (CI): 29-58%) vs. 39% (CI: 19-79%), p = 0.9, respectively). According to multivariable regression models, the robotic approach did not significantly influence estimated blood loss (EBL) (ß = -40, 95% CI: -103, 22; p = 0.2) and significantly increased operative time (OT) (ß = 28, 95% CI: 10, 46; p = 0.002). No Clavien-Dindo III-V complications were reported in the robotic group. CONCLUSION: Both, the open as well as the robot-assisted approach for PSMA-RGS had comparable oncological outcomes. No safety concerns arose for the robotic-assisted approach offering a potentially improved quality of life for patients.

EAU Biochemical Recurrence Risk Classification and PSA Kinetics Have No Value for Patient Selection in PSMA-Radioguided Surgery (PSMA-RGS) for Oligorecurrent Prostate Cancer.

OBJECTIVE: To assess the influence of biochemical recurrence (BCR) risk groups and PSA kinetics on the outcomes of radioguided surgery against prostate-specific membrane antigen (PSMA-RGS). Currently, neither BCR risk group nor PSA doubling time (PSA-DT), or PSA velocity (PSA-V) are actively assigned or relevant for counseling prior to PSMA-RGS. METHODS: We retrospectively analyzed PSMA-RGS cases for oligorecurrent prostate cancer between 2014 and 2023. BCR risk groups, PSA-DT, and PSA-V were analyzed as predictors for complete biochemical response (cBR, PSA < 0.2 ng/mL), BCR-free, and therapy-free survival (BCRFS, TFS). RESULTS: Of 374 included patients, only 21/374 (6%) and 201/374 (54%) were classified as low- and high-risk BCR (no group assignment possible in 152/374, 41%). A total of 13/21 (62%) patients with low- and 120/201 (60%) with high-risk BCR achieved cBR (p = 1.0). BCR classification was no predictor for BCRFS (HR:1.61, CI: 0.70-3.71, p = 0.3) or subsequent TFS (HR:1.07, CI: 0.46-2.47, p = 0.9). A total of 47/76 (62%) patients with PSA-DT ≤ 6 mo and 50/84 (60%) with PSA-DT > 6 mo achieved cBR (p = 0.4). PSA-DT was not associated with cBR (OR: 0.99, CI: 0.95-1.03, p = 0.5), BCRFS (HR: 1.00, CI: 0.97-1.03, p = 0.9), or TFS (HR: 1.02, CI: 0.99-1.04, p = 0.2). Consistent negative findings were recorded for PSA-V. CONCLUSIONS: The BCR risk groups and PSA kinetics do not predict the oncological success of PSMA-RGS performed at low absolute PSA values. Indolent low-risk BCR is rarely treated by PSMA-RGS.

Uncommon Haemorrhagic Cystitis of Infectious Origin: A Narrative Review for Urologists.

Purpose: Haemorrhagic cystitis may be due to different etiologies with infectious diseases representing an insidious cause to diagnose. The aim of this narrative review is to provide a comprehensive overview of less common but difficult-to-diagnose causes of infectious haemorrhagic cystitis of bacterial, mycobacterial, and parasitic origin, Moreover, we highlight possible diagnostic tools and currently available treatment options in order to give an updated tool for urologists to use in daily practice. Patients and Methods: The search engine PubMed was used to select peer-reviewed articles published from 1/Jan/2010 to 31/Aug/2022. Results: Bacteria, fungal, TB and schistosomiasis are uncommon causes of haemorrhagic cystitis burdened by high morbidity, especially if not promptly diagnosed. Conclusion: Because haemorrhagic cystitis ranges in severity from mild dysuria associated with pelvic discomfort to severe life-threatening haemorrhage, punctual diagnosis, and immediate treatment are essential to avoid further complications.

Safety and efficiency of repeat salvage lymph node dissection for recurrence of prostate cancer using PSMA-radioguided surgery (RGS) after prior salvage lymph node dissection with or without initial RGS support.

BACKGROUND AND OBJECTIVE: Metastasis-directed therapy is a feasible option for low PSA, recurrent locoregional metastatic prostate cancer. After initial salvage surgery, patients with good response might consider a repeat salvage surgery in case of recurrent, isolated, and PSMA-positive metastases. This analysis aimed to evaluate the oncological outcome and safety of repeat PSMA-targeted radioguided surgery (RGS) after either prior RGS or "standard" salvage lymph node dissection (SLND). MATERIALS AND METHODS: We identified 37 patients undergoing repeat RGS after prior SLND (n = 21) (SLND-RGS) or prior RGS (n = 16) (RGS-RGS) between 2014 and 2021 after initial radical prostatectomy with or without pelvic radiation therapy at two German tertiary referral centers. Kaplan-Meier analyses and uni-/multivariable Cox regression models were used to investigate factors associated with biochemical recurrence-free survival (BRFS) and treatment-free survival (TFS) after repeat salvage surgery. RESULTS AND LIMITATIONS: Complete Biochemical Response (cBR, PSA < 0.2 ng/ml) was observed in 20/32 patients (5 NA). Median overall BRFS [95% confidence interval (CI)] after repeat salvage surgery was 10.8 months (mo) (5.3-22). On multivariable regression, only age (HR 1.09, 95% CI 1.01-1.17) and preoperative PSA (HR 1.23, 95% CI 1.01-1.50) were associated with shorter BRFS, although PSA (HR 1.16, 95% CI 0.99-1.36) did not achieve significant predictor status in univariable analysis before (p value = 0.07). Overall, one year after second salvage surgery, 89% of the patients (number at risk: 19) did not receive additional treatment and median TFS was not reached. Clavien-Dindo grade > 3a complications were observed in 8% (3/37 patients). Limitations are the retrospective evaluation, heterogeneous SLND procedures, lack of long-term follow-up data, and small cohort size. CONCLUSION: In this study, repeat RGS was safe and provided clinically meaningful biochemical recurrence- and treatment-free intervals for selected cases. Patients having low preoperative PSA seemed to benefit most of repeat RGS, irrespective of prior SLND or RGS or the time from initial RP/first salvage surgery.

Z-shaped running suture for outer layer renorrhaphy during robot-assisted partial nephrectomy.

BACKGROUND: The aim of this study was to describe a novel outer layer renorrhaphy strategy during robot-assisted partial nephrectomy. METHODS: This technique is presented in key steps. Renorrhaphy is performed with a double layer technique. The novel strategy of outer layer renorrhaphy is to approach the parenchymal margins in a zigzag-shaped manner with a 2-0 Vicryl running suture. Each pass begins immediately adjacent to the exit site. The needle is passed through the defect and the exiting suture is secured with a Hem-o-lok clip. At each exit site, the suture is secured with a Hem-o-lok clip. A second Hem-o-lok clip is placed at the loose ends, to tighten the suture in the clip locking mechanism. Patients submitted to robot-assisted partial nephrectomy at a single institution between January 2017 and January 2022 were included in the analysis. Descriptive statistics of baseline characteristics and surgical, pathological, and oncological outcomes were analyzed. RESULTS: One hundred fifty-nine consecutive patients were recorded; 103 (64.8%) of them presented with a cT1a renal mass. Median (interquartile range [IQR]) total operative time was 146 (120-182) minutes. There was no conversion to open surgery, while 5 (3.1%) patients were converted to radical nephrectomy. We reported an overall low rate of postoperative complications. There were 5 documented perirenal hematomas and 6 cases of urinary leakage (2 pT2a, 2 pT1b, 2 pT1a renal cell carcinoma). CONCLUSIONS: Z-shaped technique is a feasible and safe alternative for renorrhaphy of the outer layer, in experienced hands. Future comparative studies are needed to confirm our results.
