Objectives: Our objective was to assess the rate of complications and gastrointestinal adverse effects of rectal spacer insertion for salvage post prostatectomy radiation therapy. Methods: A retrospective observational study was performed. Between September 2018 and March 2022, 64 post-radical prostatectomy patients who were planned for salvage radiation therapy received a rectal spacer. The selected patients were those who had nerve-sparing prostatectomy with intrafascial or interfascial dissections (where Denonvillier’s fascia is retained). Radiation dose to the rectal wall and gastrointestinal symptoms were assessed. Symptoms were graded using the National Cancer Center Institute Common Terminology Criteria for Adverse Events v4.0 grading scheme. A total of 39 patients had pre-spacer planning computer tomography (CT) scans, and the rectal dose before and after the spacer insertion was calculated. Comparisons were made using the Student’s t-test, with a p-value < 0.05 representing statistical significance. Finally, clinicians were surveyed to rate the ease of the procedure using a 5-point Likert scale of 1 to 5 (1: very difficult, 2: difficult, 3: moderate, 4: easy, 5: very easy). Results: A total of 64 patients successfully underwent rectal spacer insertion. The mean age was 64.4 years (standard deviation: 5.7 years). After a median of 14 months’ (range 6 to 35) follow up, acute grade 1 and above gastrointestinal (GI) toxicities were seen in 28% of patients (grade 2 in 1.5%), and late grade 1 and above GI toxicities were seen in 12% of patients (grade 2 in 1.5%). Amongst the 39 patients with pre-spacer planning CT images, the volume of the rectum receiving 60%, 70%, 80%, 90%, and 100% of the prescribed radiation dose was reduced by 25.9%, 34.2%, 35.4%, 43.7%, and 61.7%, respectively. All dose reductions were statistically significant. The procedure was rated as “easy” or “very easy” to perform in 56% of cases. Conclusions: The insertion of a rectal spacer in selected patients undergoing PPRT is feasible and safe and significantly improves rectal wall radiation dosimetry in salvage post prostatectomy radiation therapy. It was accomplished in >95% of patients, increasing vesico-rectal separation from ‘immediate vicinity’ to 11 mm without any post-operative complications in experienced hands. In addition, it achieved significant reduction in rectal radiation doses, leading to low rates of acute and late grade 2 toxicity.

Objectives: Few studies have examined the role of prostate MRI in patients with suspicious digital rectal examination (DRE) and/or PSA > 10 ng/mL. In a cohort of non-screened patients with suspicious DRE, we investigated the rate of avoidable prostate biopsies and potentially missed clinically significant prostate cancer (csPCa) with negative MRI, and the concordance between targeted biopsy (TBx) and systematic biopsy (SBx) in detecting csPCa with positive MRI. Methods: We retrospectively examined 199 biopsy-naïve patients with suspicious DRE who underwent prostate MRI before transperineal biopsy. Prostate Imaging—Reporting and Data System (PI-RADS) v2.1 ≥ 3 category of the index lesion defined a positive MRI. Combined TBx/SBx and SBx alone were performed for positive and negative MRI, respectively. An International Society of Urogenital Pathology Grade Group ≥ 2 defined csPCa. We calculated the csPCa detection rate of TBx, SBx, and combined TBx/SBx. The Cohen kappa statistic was used to measure the concordance between TBx and SBx. Results: Ninety-one (45.7%) csPCa cases were detected. MRI was positive in 153 (76.9%) patients. In the 46 patients with negative MRI, SBx detected 5 (10.9%) csPCa cases. Prostate biopsy could, thus, be avoided in 41/199 (20.6%) patients at the cost of missing 5/91 (5.5%) csPCa cases. The concordance between TBx and SBx in detecting csPCa with positive mpMRI was substantial (k = 0.70). Specifically, 6/86 (6.9%) csPCa cases were detected with TBx, and 17/86 (19.7%) with SBx alone. Concordance was almost perfect (k = 0.82) in patients with PSA > 10 ng/mL. Only 4/38 (10.5%) csPCa cases were missed by TBx, and only 1 (2.6%) csPCa case was identified by TBx alone. Conclusions: MRI in patients with suspicious DRE could avoid roughly 21% of unnecessary biopsies at the cost of missing approximately 6% of csPCa cases. Moreover, MRI and TBx complemented SBx in detecting csPCa in the subgroup with PSA > 10 ng/mL.

Urinary tract infections (UTIs) are highly prevalent and have significant implications for patients. As internet-based health information becomes more relied upon, ChatGPT has emerged as a potential source of healthcare advice. In this study, ChatGPT-3.5 was subjected to 16 patient-like UTI queries, with its responses evaluated by a panel of urologists. ChatGPT can address general UTI questions and exhibits some reasoning capacity in specific contexts. Nevertheless, it lacks source verification, occasionally overlooks vital information, and struggles with contextual clinical advice. ChatGPT holds promise as a supplementary tool in the urologist’s toolkit, demanding further refinement and validation for optimal integration.

Metallic prostate stapling (e.g., UroLift) is a minimally invasive treatment option for men with bladder outlet obstruction from benign prostatic hyperplasia (BPH). While it provides rapid relief and preserves sexual function, unexpected interactions with other medical devices can compromise surgical procedures. In this letter, we highlight five cases where stapled metallic implants resulted in damage to bipolar energy device during transurethral resection of the prostate (TURP) and stimulation of obturator nerve. Laser may also reflect off metallic prostate implants which can result in laser equipment malfunction. Monopolar TURP should be considered in patients with existing metallic prostate implants who need further transurethral surgery for obstructive BPH to prevent bipolar instrument damage and obturator kick.

Electronic cigarette use is rising globally. Although it may represent a potential smoking cessation tool, amidst misinformation and social media promotion, there is a growing concern regarding the health risks associated with its usage. These risks include adverse effects on the genitourinary system. This commentary investigates the genitourinary effects of approved smoking cessation tools versus electronic cigarettes, urging urologists to prioritize established methods over electronic cigarettes due to their potential for multisystem toxicity and uncertain long-term health implications. Further research is warranted to evaluate comprehensively the genitourinary effects of these interventions.

Objectives: Proximal and distal bulbar urethral strictures (BUS) have different disease characteristics and require different treatment strategies despite being regarded as a single condition. To clarify the differences, we analyzed our database by distinguishing the two types of BUS. Methods: We retrospectively reviewed the data of 196 patients with BUS who underwent urethroplasty at the National Defense Medical College (Japan) between August 2004 and March 2022. We divided patients into proximal (group 1) or distal (group 2) groups based on the stricture segment and compared patient background and surgical techniques for each group. We assessed whether the stricture segment was an independent predictive factor for substitution urethroplasty selection using multivariate logistic regression analysis. The recurrence rates were calculated and compared using the Kaplan–Meier method and log-rank test, respectively. Results: Patients in group 1 had a less frequent non-obliterated lumen (73% vs. 94%, p = 0.020) and significantly shorter strictures (10 mm vs. 23 mm, p < 0.001) more frequently caused by external traumas (47% vs. 26%, p = 0.010) than those in group 2. Logistic regression analysis revealed that the stricture segment (distal) (p < 0.001), stricture length (≥20 mm) (p < 0.001), ≥2 prior transurethral procedures (p = 0.030), and a non-obliterated lumen (p = 0.020) were independent predictive factors for substitution urethroplasty. However, the recurrence rate (p = 0.18) did not significantly differ between the two groups. Conclusions: Proximal and distal BUS have substantially different anatomical characteristics and etiologies and require different reconstructive techniques.

Introduction: Percutaneous nephrolithotomy (PCNL) is the standard procedure for treating large kidney stones, especially those measuring over 20 mm or staghorn stones. Accurate placement of the tract into the renal collecting system of interest is crucial. Objective: To compare the free-hand puncture technique with robotic-assisted puncture during fluoroscopy-guided PCNL on a phantom kidney model in terms of efficiency and safety. A self-assessment of confidence levels after each puncture was recorded. Study Design: This prospective single-center benchtop study was conducted at the University Malaya Medical Centre (UMMC). Four urological residents participated and performed phantom punctures using both the free-hand bull’s eye technique and the automated needle targeting system with X-ray (ANT-X). Each resident performed a total of 60 punctures on the renal phantom models, with 30 punctures using the free-hand technique and 30 punctures using the ANT-X robotic-assisted system. Results: A total of 240 needle insertions were conducted, with 120 in the ANT-X group and 120 in the free-hand group. The success rate of needle insertions was 100% in both groups. However, the study revealed that the ANT-X group required, on average, an additional 51 s for needle puncture compared to the free-hand group (p < 0.001). In terms of fluoroscopic exposure, the ANT-X group exhibited significantly lower radiation exposure compared to the free-hand group (p < 0.001). Sub-analysis showed that puncture time remained consistent regardless of the technique used, but fluoroscopic screening time decreased with increasing participant experience. The ANT-X group also resulted in significantly lower radiation exposure during initial sessions compared to the free-hand technique. Surgeons’ self-assessment of confidence levels indicated a high level of confidence in needle puncture. Conclusions: Our benchtop study comparing the efficacy and safety between free-hand and ANT-X phantom punctures revealed comparable results. The needle puncture technique facilitated by the ANT-X system showed promising results in terms of reducing fluoroscopic exposure, albeit at the cost of longer operative times. This technology holds promise for novice surgeons who are in the early stages of their learning curve and might be useful for experienced surgeons looking to reduce radiation exposure.

This technology holds promise for novice surgeons who are in the early stages of their learning curve and might be useful for experienced surgeons looking to reduce radiation exposure.","PeriodicalId":21961,"journal":{"name":"Société Internationale d’Urologie Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140449828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
Background: A number of assessment methods for the pelvic floor have been described. Male pelvic floor ultrasound is an accessible, noninvasive assessment tool. Objective: To evaluate current published literature on anatomical parameters on pre- and postoperative ultrasound imaging of the male pelvic floor and correlation with continence status following radical prostatectomy (RP). Methods: A comprehensive literature search was conducted using the PRISMA guidelines to identify publications up to November 2022. Exclusion criteria consisted of animal studies, non-English articles, case reports, reviews and abstracts or reports from conferences. A full-text review was performed on 12 papers using ultrasound to assess pelvic floor anatomy and correlation with continence status following RP. Results: A total of 18 anatomical parameters were evaluated using US. Membranous urethral length (MUL), striated urethral sphincter (SUS) morphology and activation were most commonly studied. Shorter pre- and postoperative MUL, decreased preoperative SUS thickness and vascularity, postoperative discontinuity of SUS muscle fibres and decreased SUS activation are associated with post-prostatectomy incontinence (PPI). There is a paucity of data comparing anatomical changes in men prior to and following RP. The benefits of transperineal ultrasound are that it is minimally invasive, accessible, provides dynamic imaging of all three striated muscle complexes simultaneously and includes a bony landmark to reference measures of pelvic floor muscle displacement. Conclusions: Ultrasound evaluation of the male pelvic floor is an evolving field as there is development in technology and understanding of pelvic floor anatomy. It is an accessible and dynamic imaging modality, which allows both morphological and functional assessment of pelvic floor anatomy and its role in PPI. MUL and SUS morphology and activation are associated with continence status following RP. Several other anatomical parameters that may predict PPI were identified. Current literature is limited by small, single-centre studies with heterogeneous cohorts and methodologies.
背景：盆底的评估方法有很多。男性盆底超声是一种方便、无创的评估工具。目的：评估目前已发表的有关男性盆底前后解剖参数的文献：评估目前已发表的关于男性盆底术前和术后超声成像解剖学参数以及与根治性前列腺切除术（RP）后尿失禁状况相关性的文献。方法：采用PRISMA指南进行了全面的文献检索，以确定截至2022年11月的出版物。排除标准包括动物研究、非英语文章、病例报告、综述和会议摘要或报告。对 12 篇使用超声波评估盆底解剖结构以及与 RP 术后尿失禁状况相关性的论文进行了全文综述。结果：共使用 US 评估了 18 个解剖参数。最常研究的是膜尿道长度（MUL）、横纹尿道括约肌（SUS）形态和激活情况。术前和术后 MUL 较短、术前 SUS 厚度和血管减少、术后 SUS 肌纤维中断和 SUS 活性降低与前列腺切除术后尿失禁（PPI）有关。比较男性在前列腺电切术前后的解剖学变化的数据很少。经会阴超声检查的优点是微创、方便、可同时对所有三块横纹肌复合体进行动态成像，并包含一个骨性地标，可作为盆底肌肉移位测量的参考。结论随着技术的发展和对盆底解剖的了解，男性盆底超声评估是一个不断发展的领域。它是一种便捷、动态的成像方式，可对盆底解剖结构及其在 PPI 中的作用进行形态和功能评估。MUL和SUS的形态和激活与RP术后的尿失禁状况有关。研究还发现了其他一些可预测 PPI 的解剖参数。目前的文献受到小型单中心研究的限制，这些研究的队列和方法不尽相同。
