ABSTRACT

With increasing life expectancy there is also an increased need for the management of older (≥ 80 years) patients with the diagnosis of muscle-invasive bladder cancer. Radical cystectomy with urinary diversion is the state of the art treatment (with neoadjuvant chemotherapy, as long as the patient is fit enough). Choosing the best urinary diversion with respect to morbidity compared to functionality and quality of life remains a challenge in these patients. Physical age alone is not decisive for making a decision. A thorough preoperative assessment of medical features, physical and cognitive impairments is more important. Older patients are generally provided with an ileal conduit as an incontinent urinary diversion, as the intervention involves reduced operating times and complexity compared to continent urinary diversions; however, in the case of good health status with an adequate life expectancy and sufficient compliance, continent diversions may be considered even in aged candidates. In the case of multimorbid patients with a high perioperative risk, ureterostomy with permanent ureteric stents is an important alternative. Most importantly, a thorough preoperative counselling enables patients to reach an informed decision.

ABSTRACT

PURPOSE: Iatrogenic ureteral strictures (US) after endoscopic treatment for urolithiasis represent a significant healthcare concern. However, high-quality evidence on the risk factors associated with US is currently lacking. We aimed to develop a consensus statement addressing the definition, risk factors, and follow-up management of iatrogenic US after endoscopic treatment for urolithiasis. METHODS: Utilizing a modified Delphi method, a steering committee developed survey statements based on a systematic literature review. Then, a two-round online survey was submitted to 25 experts, offering voting options to assess agreement levels. A consensus panel meeting was held for unresolved statements. The predetermined consensus threshold was set at 70%. RESULTS: The steering committee formulated 73 statements. In the initial survey, consensus was reached on 56 (77%) statements. Following in-depth discussions and refinement of 17 (23%) statements in a consensus meeting, the second survey achieved consensus on 63 (86%) statements. This process underscored agreement on pivotal factors influencing US in endoscopic urolithiasis treatments. CONCLUSIONS: This study provides a comprehensive list of categorized risk factors for US following endoscopic urolithiasis treatments. The objectives include enhancing uniformity in research, minimizing redundancy in outcome assessments, and effectively addressing risk factors associated with US. These findings are crucial for designing future clinical trials and guiding endoscopic surgeons in mitigating the risk of US.

ABSTRACT

PURPOSE: We aimed to accurately determine ureteral stricture (US) rates following urolithiasis treatments and their related risk factors. METHODS: We conducted a systematic review and meta-analysis following the PRISMA guidelines using databases from inception to November 2023. Studies were deemed eligible for analysis if they included ≥ 18 years old patients with urinary lithiasis (Patients) who were subjected to endoscopic treatment (Intervention) with ureteroscopy (URS), percutaneous nephrolithotomy (PCNL), or shock wave lithotripsy (SWL) (Comparator) to assess the incidence of US (Outcome) in prospective and retrospective studies (Study design). RESULTS: A total of 43 studies were included. The pooled US rate was 1.3% post-SWL and 2.1% post-PCNL. The pooled rate of US post-URS was 1.9% but raised to 2.7% considering the last five years' studies and 4.9% if the stone was impacted. Moreover, the pooled US rate differed if follow-ups were under or over six months. Patients with proximal ureteral stone, preoperative hydronephrosis, intraoperative ureteral perforation, and impacted stones showed higher US risk post-endoscopic intervention with odds ratio of 1.6 (P = 0.05), 2.6 (P = 0.009), 7.1 (P < 0.001), and 7.47 (P = 0.003), respectively. CONCLUSIONS: The overall US rate ranges from 0.3 to 4.9%, with an increasing trend in the last few years. It is influenced by type of treatment, stone location and impaction, preoperative hydronephrosis and intraoperative perforation. Future standardized reporting and prospective and more extended follow-up studies might contribute to a better understanding of US risks related to calculi treatment.

ABSTRACT

Introduction: Urachal cancer (UrC) is a rare, non-urothelial malignancy. Its natural history and management are poorly understood. Although localized to the bladder dome, the most common histological subtype of UrC is adenocarcinoma. UrC develops from an embryonic remnant, and is frequently diagnosed in advanced stage with poor prognosis. The treatment is not standardized, and based only on case reports and small series. This large retrospective multicentric study was conducted by the French Genito-Urinary Tumor Group to gain a better understanding of UrC. Material and Methods: data has been collected retrospectively on 97 patients treated at 22 French Cancer Centers between 1996 and 2020. Results: The median follow-up was 59 months (range 44-96). The median age at diagnosis was 53 years (range 20-86), 45% were females and 23% had tobacco exposure. For patients with localized disease (Mayo I-II, n=46) and with lymph-node invasion (Mayo III, n=13) median progression-free-survival (mPFS) was 31 months (95% CI: 20-67) and 7 months (95% CI: 6-not reached (NR)), and median overall survival (mOS) was 73 months (95% CI: 57-NR) and 22 months (95% CI: 21-NR) respectively. For 45 patients with Mayo I-III had secondary metastatic progression, and 20 patients were metastatic at diagnosis. Metastatic localization was peritoneal for 54% of patients. Most patients with localized tumor were treated with partial cystectomy, with mPFS of 20 months (95% CI: 14-49), and only 12 patients received adjuvant therapy. Metastatic patients (Mayo IV) had a mOS of 23 months (95% CI: 19-33) and 69% received a platin-fluorouracil combination treatment. Conclusion: UrC is a rare tumor of the bladder where patients are younger with a higher number of females, and a lower tobacco exposure than in standard urothelial carcinoma. For localized tumor, partial cystectomy is recommended. The mOS and mPFS were low, notably for patients with lymph node invasion. For metastatic patients the prognosis is poor and standard therapy is not well-defined. Further clinical and biological knowledge are needed.

ABSTRACT

The reprocessing of medical products is an important topic both in urological practices and in hospitals. The complexity is caused by the increasing variety of medical instruments and also by the increasing demands on the legally required quality of the reprocessing. The Robert Koch Institute (RKI) and the Federal Institute for Drugs and Medical Devices (BfArM) have published recommendations for the processing of MD and last updated them in 2012. This article summarizes the legal framework for the reprocessing of medical devices, how medical devices are categorized before the appropriate procedure for reprocessing can be selected and the various steps in the reprocessing. A special focus is placed on medical products that are typically found in urological practices or outpatient departments and are processed there. Furthermore, the necessity of validating the processing method and the required training (expertise) of the personnel are discussed.

ABSTRACT

BACKGROUND: En bloc tumor resection of bladder tumors (ERBT) is a novel alternative procedure to conventional resection of bladder tumor (cTURBT), which might help to address common problems of the standard method, such as inadequate detrusor muscle in specimens, high re-resection rates and high recurrence rates. OBJECTIVE: To analyze current data on ERBT in efficacy and safety compared to cTURBT. DATA SOURCES: PubMed. STUDY SELECTION: Two independent authors identified trials based on keywords and inclusion criteria. A third author was consulted in case of discrepancies. Screening keywords: ERBT, en bloc transurethral resection of bladder tumor, TURBT en bloc. A meta-analysis of 13 studies was performed. The effect size was estimated based on odds ratios and mean differences including their corresponding two-sided 95% confidence intervals. DATA SYNTHESIS: The analyzed studies comprised a homogenous collective in terms of tumor size, tumor multiplicity and tumor stage. Operation time did not significantly differ between the methods. Differences were observed in hospitalization and catheterization time in favor of ERBT. Reported complications did not show clear differences. There was significantly more detrusor muscle in the specimens in the ERBT group. No significant differences were found in recurrence up to 2 years of follow-up. CONCLUSION: ERBT is a safe alternative to conventional TURBT with promising features regarding effective resection of detrusor muscle. More standardized data on recurrence rates, different resection modalities and resection margin results are needed.

ABSTRACT

Transurethral resection of bladder tumors (TURBT) is the standard of care for the diagnostics and primary treatment of bladder tumors. These are removed by fragmentation using loop diathermy. The resection area is coagulated for hemostasis. An important aspect is always a complete resection with an adequate amount of detrusor muscle in the specimen. Postoperative intravesical instillation of single-shot chemotherapy has been proven to reduce recurrence rates. Methods for improved tumor visualization (particularly photodynamic diagnostics) are used to enhance tumor detection rates particularly in multifocal tumors or carcinoma in situ (CIS). Thus, recurrence and progression rates can be reduced. Depending on the histological examination of the TURBT specimen, follow-up treatment for non-muscle invasive bladder tumors are adjuvant instillation treatment using chemotherapy or Bacillus Calmette-Guérin (BCG), second look TURBT and early cystectomy or for muscle invasive bladder tumors, radical cystectomy or (oncologically subordinate) trimodal treatment with renewed TURBT, radiotherapy and chemotherapy are indicated. Possible complications of TURBT include bleeding with bladder tamponade, extraperitoneal or intraperitoneal bladder perforation and infections of the urogenital tract.

ABSTRACT

PURPOSE: To summarize the current evidence and the reasons to go for thulium-based anatomical endoscopic enucleation of the prostate (AEEP). METHODS: This review discusses the available literature on thulium-based AEEP. RESULTS: Thulium lasers operate at a wavelength between 1940 and 2013 nm. This wavelength, which has a low penetration depth in water, allows to perform smooth cuts in the prostatic tissue and allows urologists to perform various procedures: resection, vaporization, enucleation, or vapoenucleation of the prostate. Depending on the type of thulium laser, it can be used either in a continuous, or pulsed mode. CONCLUSION: In recent years, an increasing amount of evidence has described the thulium laser as a minimally invasive and size-independent treatment option for benign prostatic enlargement with excellent long-term results.

ABSTRACT

PURPOSE: Various techniques for EEP exist. They differ by surgical steps and the source of energy. It is assumed that the latter is of minor importance, whereas adherence to the anatomical enucleation template determines the postoperative result. So far, no systematic review highlights the differences between the energy sources in use for anatomical EEP. This study will address selfsame topic. METHODS: A systematic review of the literature was completed on September 1st, 2020. Studies comparing HoLEP, ThuLEP, DiLEP, or BipolEP with TUR-P providing 12 months of postoperative follow-up were included. Two frequentist network meta-analyses were created to compare the techniques of EEP indirectly. RESULTS: 31 studies, including 4466 patients, were found eligible for our meta-analysis. Indirect pairwise comparison showed differences in surgery time between BipolEP and HolEP (MD - 16.72 min., 95% CI - 27.75 to - 5.69) and DiLEP and HoLEP (MD - 22.41 min., 95% CI - 39.43 to - 5.39). No differences in the amount of resected prostatic tissue, major and minor complications and postoperative catheterization time were found. The odds for blood transfusions were threefold higher for BipolEP than for HoLEP (OR 3.27, 95% CI 1.02-10.5). The difference was not statistically significant when comparing prospective trials and matched-pair analysis only (OR 3.25, 95% CI 0.94-11.18). The Qmax 12 months after surgery was 2 ml/sec. higher for BipolEP than for DiLEP (MD 2.00, 95% CI 0.17-3.84) and 1.94 ml/sec. lower for DiLEP than for HoLEP (MD - 1.94, 95% CI - 3.65 to - 0.22). CONCLUSION: The energy source used for EEP has an impact on the intervention itself. BipolEP promotes surgical efficiency; laser techniques lower the risk of bleeding. REGISTRY: This meta-analysis is registered in the PROSPERO international prospective register registry with the registration number CRD42020205836.

ABSTRACT

INTRODUCTION: Due to demographic changes in today's society, the number of patients with lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH) is increasing. Similarly, the proportion of patients with cardiovascular risk factors undergoing antiplatelet (AP) or anticoagulation (AC) therapy is growing as well. METHODS: This review discusses the current literature on various techniques used for anatomic endoscopic enucleation of the prostate (AEEP) in patients on AC/AP therapy. RESULTS: The large number of energy sources used for AEEP makes it difficult to compare them. Overall, fewer bleeding-associated complications arise in patients under AP compared to AC or bridging therapy with low molecular weight heparin. However, perioperatively both AP and AC therapy lead to a higher risk of bleeding complications compared to patients not taking anticoagulants. CONCLUSIONS: The literature shows that AEEP is possible and efficacious in patients under AC/AP therapy, with only slight differences compared to patients not taking AC/AP drugs, on a short and long-term basis. Nevertheless, the sparse data, the retrospective nature of many studies and the inclusion of prostate sizes between 50 and 110 ml only, make it difficult to come to strong conclusions.

ABSTRACT

BACKGROUND: In an aging society an increase of benign prostatic obstruction (BPO) requiring treatment is to be expected and the proportion of patients with cardiovascular comorbidities under anticoagulation is also increasing. As the operative treatment of BPO can be problematic, the hemostatic effect of the techniques is of particular importance. OBJECTIVE: This review article discusses the data situation on the bleeding risk of established surgical techniques and the statement of the European Association of Urology (EAU) guidelines "EAU guidelines on management of non-neurogenic male lower urinary tract symptoms (LUTS), incl. benign prostatic obstruction (BPO)" on this topic. MATERIAL AND METHODS: Data analysis from PubMed. RESULTS: The EAU guidelines favor transurethral laser vaporization of the prostate using "greenlight", thulium or diode laser and laser enucleation using a holmium or thulium laser in this patient collective. The bipolar is superior to monopolar transurethral resection (TUR-P) in hemostasis. In the future bipolar enucleation of the prostate (BipoLEP) can be an alternative under good hemostasis. Bleeding is a rare complication after recently established minimally invasive techniques, such as Urolift®, I­TIND© and Rezum™, the same applies to prostate artery embolization. Aqua-ablation/AquaBeam® seems to be unsuitable due to frequent hematuria. Surgical adenomectomy can be associated with a high risk of bleeding. CONCLUSION: According to current data, transurethral laser vaporization and enucleation of the prostate are the treatment of choice for patients under anticoagulation; however, other transurethral techniques, such as BipoLEP have an acceptable risk of bleeding and can be an alternative depending on local resources. Newer minimally invasive approaches could become more important in the future.

ABSTRACT

A 52-year-old man with flank pain on the right side presented to the emergency room. A computer tomography of the abdomen showed a right ureterolithiasis with 3.5 mm stone in the proximal ureter with consecutive grade 2 hydronephrosis. After standard treatment of the right ureterolithiasis, there was a relapse on the left side and throughout the entire upper and lower urinary tract with struvite stones due to a persistent infection with Proteus mirabilis.

ABSTRACT

Both the demographic shift and progress in medicine are resulting in an increasingly longer life expectancy. It is presumed that a mean age of 90 years will be achieved within the next decade in many countries. Thus, geriatric medicine, which is committed to the specific needs of older, often frail and frequently comorbid patients, is becoming increasingly more important. The prevalence of infections of the genitourinary tract increases with age, simultaneously, a critical and conscious use of antibiotics is required in terms of antimicrobial treatment. The intention of the present review is to make the reader aware of the specific characteristics of urinary tract infections and asymptomatic bacteriuria in the older patient population in terms of epidemiology, spectrum of pathogens and resistance as well as the indications for and performance of antimicrobial treatment.

ABSTRACT

BACKGROUND: Benign prostatic hyperplasia (BPH) is the most common condition affecting the male lower urinary tract. Besides transurethral resection of the prostate (TURP), vaporization of the prostate and endoscopic enucleation of the prostate are available. OBJECTIVES: To provide an overview of the current status of surgical therapies for BPH. MATERIALS AND METHODS: Narrative review of the literature on the surgical treatment of BPH. RESULTS: Besides TURP, which still can be regarded as the reference technique for surgical treatment of BPH in men with a prostate volume <80 cc, greenlight laser vaporization of the prostate (GLV) and endoscopic enucleation of the prostate (EEP) are established and evidence-based alternatives. A multitude of prospective randomized trials could show comparable functional outcomes of GLV or EEP in comparison to TURP. Based on lower comorbidity and comparable outcomes, bipolar TURP rather than monopolar TURP should be regarded as the surgical reference technique. In patients with ongoing oral anticoagulation of thrombocyte aggregation inhibition, GLV provides high intra- und postoperative safety. Endoscopic enucleation of the prostate is the only transurethral surgical method which provides high level evidence concerning safety and efficacy in patients with prostates >80 cc. CONCLUSIONS: Choice of surgical treatment of BPH should be individualized and based on prostate size, comorbidities and surgical experience.

ABSTRACT

The spectrum of surgical procedures for the minimally invasive treatment of benign prostatic hyperplasia (BPH) has significantly increased over the last two decades. The simple suprapubic prostatectomy (subtotal prostatectomy, SP) has largely lost relevance in current practice. On the other hand, transurethral resection of the prostate (TURP) has been further standardized and potentially made safer by the introduction of the bipolar technique and low-pressure systems.Transurethral (endoscopic) enucleation techniques (endoscopic enucleation of the prostate, EEP) are increasingly competing with the current gold standard TURP and are replacing SP for treatment of larger adenomas. This approach is especially related to the rapid development of laser technology, which has sustainably changed the face of modern BPH treatment in a similar way to stone therapy. This has been incorporated in the clinical patient management, clinical studies and standardization of numerous surgical techniques that are systematically described in this article. Additionally, efforts have also been made to use other energy sources, such as bipolar current in EEP. With respect to scientific objectivity, high-quality clinical trials are regularly published which further strengthen the position of EEP.

ABSTRACT

PURPOSE: Aquablation of the prostate using the AquaBeam™ system promises equivalent functional outcomes, reduced learning curve, and improved sexual function compared to transurethral prostate resection as shown in prospective randomized trials. This prospective cohort study aims to evaluate if published results can be transferred into the clinical routine in a non-selected patient collective. METHODS: This study includes all patients treated between September 2017 and June 2018 with Aquablation of the prostate. Patients have been evaluated prospectively for the perioperative course and early follow-up. Besides voiding parameter and symptom score, TRUS-volume change, ejaculatory function, and adverse events have been recorded. RESULTS: 118 consecutive patients have been treated in the given time. Aquablation could be carried out successfully in all patients. IPSS, QoL, Qmax, and PVR improved significantly after the procedure and continued to improve during 3-month follow-up. Mean OR time was 20 min, TRUS volume decreased by 65%, and 73% of the patients retained antegrade ejaculation. Thirteen adverse events (> Clavien-Dindo I) occurred in 10 patients. CONCLUSION: The surgical ablation of the prostate using Aquablation achieved significant and immediate improvement of functional voiding parameters Qmax and PVR as well as symptomatic improvement of IPSS and QoL. Aquablation seems to be safe and effective with a low perioperative complication profile even in a non-selected group of patients.

ABSTRACT

OBJECTIVE: To compare open simple prostatectomy, endoscopic enucleation and laparoscopic, robot-assisted enucleation of high-volume prostate in terms of operation time, blood loss, transfusion and complication rates and early continence rates. MATERIAL AND METHODS: Patients with BPH treated endoscopically (ThuVEP, Hamburg and Hannover) or robotically (Mainz) were evaluated prospectively for prostate size, free flow and validated questionnaires (IPSS, QoL). 35 patients were matched to patients after open prostatectomy (Mainz) for age, prostate size, IPSS and QoL scores. Operation time was noted from the first cut to the last suture; blood loss was estimated by the drop of haemoglobin preoperatively and one day after surgery. Transfusion rates were documented. Early continence was estimated by pad use over the first 24 h after catheter removal. Statistical analysis was performed with SPSS 22.0. RESULTS: No significant differences in prostate size, age and preoperative questionnaires were found (p > 0.3). Postoperative flow and the results of the questionnaires were significantly improved (all p < 0.05), without difference between the approaches (p > 0.8). Endoscopic surgery showed superiority in operation time (both p < 0.05); blood loss and transfusion rates were significantly lower compared to open surgery (both p < 0.01) and lower than in robotic surgery without reaching significance (p = 0.18, p = 0.36). Similar results were seen in early continence rates. CONCLUSION: Due to our results, endoscopic surgery should be considered as first-line therapy unless there are comorbidities like diverticula and/or bladder calculi that can be easily treated simultaneously by robotic surgery. Against the background of these findings, indications favouring open surgery are getting sparse.
