RESUMO

PURPOSE: The aim of this study was to assess the post biopsy infection rate, feasibility and prostate cancer (PCa) detection rate (CDR) by performing transperineal MRI-TRUS fusion biopsy of the prostate (TPBx) under local anesthesia (LA) without antibiotic prophylaxis (AP). METHODS: We prospectively screened 766 men with suspicious lesions on mpMRI, an elevated PSA level or a suspect digital examination undergoing MRI-TRUS-TPBx in LA, from May 2019 to July 2020. Patients with the need for antibiotic prophylaxis or without a PI-RADS target lesion were excluded from final analyses. We reported CDR, perioperative pain (0-10) and postoperative complications. PCa with an ISUP grade ≥ 2 was classified as clinically significant PCa (csPCa). RESULTS: We included 621 patients with a median age of 68 years (IQR 62-74), a PSA of 6.43 ng/mL (IQR 4.72-9.91) and a prostate volume of 45 cc (IQR 32-64). In median, 4 targeted (TB) (IQR 3-4) and 6 (IQR 5-7) systematic biopsies (SB) detected in combination overall 416 (67%) PCa and 324 (52%) csPCa. Overall CDR of TB for PI-RADS 3, 4 and 5 was 26%, 65% and 84%, respectively. Patients reported a median perioperative pain level of 2 (IQR 1-3). Four patients (0.6%) developed a post biopsy infection, one experienced urosepsis. CONCLUSION: Our results demonstrate that transperineal MRI-TRUS fusion-guided prostate biopsy under LA without AP is feasible, safe and well tolerated.

RESUMO

PURPOSE: To assess the efficacy, safety, and outcome of image-guided high-dose-rate (HDR) brachytherapy in patients with adrenal gland metastases (AGM). MATERIALS AND METHODS: From January 2007 to April 2014, 37 patients (7 female, 30 male; mean age 66.8 years, range 41.5-82.5 years) with AGM from different primary tumors were treated with CT-guided HDR interstitial brachytherapy (iBT). Primary endpoint was local tumor control (LTC). Secondary endpoints were time to untreatable progression (TTUP), time to progression (TTP), overall survival (OS), and safety. In a secondary analysis, risk factors with an influence on survival were identified. RESULTS: The median biological equivalent dose (BED) was 37.4 Gy. Mean LTC after 12 months was 88%; after 24 months this was 74%. According to CTCAE criteria, one grade 3 adverse event occurred. Median OS after first diagnosis of AGM was 18.3 months. Median OS, TTUP, and TTP after iBT treatment were 11.4, 6.6, and 3.5 months, respectively. Uni- and multivariate Cox regression analyses revealed significant influences of synchronous disease, tumor diameter, and the total number of lesions on OS or TTUP or both. CONCLUSION: Image-guided HDR-iBT is safe and effective. Treatment- and primary tumor-independent features influenced survival of patients with AGM after HDR-iBR treatment.

RESUMO

Irreversible electroporation (IRE), a new tissue ablation procedure available since 2007, could meet the requirements for ideal focal therapy of prostate cancer with its postulated features, especially the absence of a thermal ablation effect. Thus far, there is not enough evidence of its effectiveness or adverse effects to justify its use as a definitive treatment option for localized prostate cancer. Moreover, neither optimal nor individual treatment parameters nor uniform endpoints have been defined thus far. No advantages over established treatment procedures have as yet been demonstrated. Nevertheless, IRE is now being increasingly applied for primary prostate cancer therapy outside clinical trials, not least through active advertising in the lay press. This review reflects the previous relevant literature on IRE of the prostate or prostate cancer and shows why we should not adopt IRE as a routine treatment modality at this stage.

RESUMO

A more than 100-year period, where the prostate was only seen and treated as a whole is coming to an end right now. Finally, high resolution imaging is providing deep insights and detailed information so that new therapeutic procedures can aim for the smallest targets within the gland. The long-standing wish of patients for individual noninvasive diagnostics and treatment of prostate diseases can now be fulfilled by providing new tailored concepts; however, in order to transfer the enormous amount of new information into the specific clinical patient situation, a closely knit interdisciplinary approach is required. In this setting, the traditional outpatient consultation service is overstretched in every aspect. It is now the time for new innovative constructs. The current one-sided service concept for urologists, radiologists and radiation therapists is therefore behind the times and the development of a "prostate management team" with equally cooperating partners from each specialty is the task for the future.

RESUMO

PURPOSE: To reach standardized terminology in focal therapy (FT) for prostate cancer (PCa). METHODS: A four-stage modified Delphi consensus project was undertaken among a panel of international experts in the field of FT for PCa. Data on terminology in FT was collected from the panel by three rounds of online questionnaires. During a face-to-face meeting on June 21, 2015, attended by 38 experts, all data from the online rounds were reviewed and recommendations for definitions were formulated. RESULTS: Consensus was attained on 23 of 27 topics; Targeted FT was defined as a lesion-based treatment strategy, treating all identified significant cancer foci; FT was generically defined as an anatomy-based (zonal) treatment strategy. Treatment failure due to the ablative energy inadequately destroying treated tissue is defined as ablation failure. In targeting failure the energy is not adequately applied to the tumor spatially and selection failure occurs when a patient was wrongfully selected for FT. No definition of biochemical recurrence can be recommended based on the current data. Important definitions for outcome measures are potency (minimum IIEF-5 score of 21), incontinence (new need for pads or leakage) and deterioration in urinary function (increase in IPSS >5 points). No agreement on the best quality of life tool was established, but UCLA-EPIC and EORTC-QLQ-30 were most commonly supported by the experts. A complete overview of statements is presented in the text. CONCLUSION: Focal therapy is an emerging field of PCa therapeutics. Standardization of definitions helps to create comparable research results and facilitate clear communication in clinical practice.

RESUMO

INTRODUCTION: Inguinal hernias are the most common hernias in adult males. Abnormalities should be taken into account for therapeutic procedures. This is the first report of a dislocation of a primary orthotopic kidney in a monstrous inguinal intestinal hernia. CASE PRESENTATION: This paper reports an incidental finding of a dislocation of a primary orthotopic kidney in a monstrous inguinal intestinal hernia of an 82-year-old patient with intracranial injury and acute kidney failure. Post-renal kidney failure could be excluded by ultrasound and CT examination. The acute renal decompensation resulted from rhabdomyolysis associated with a falling down trauma with crush syndrome and pneumonic septicaemia based on chronic renal failure associated with nephrosclerosis and ureteropelvic junction obstruction conditioned atrophic right kidney. CONCLUSION: Previous reports in the literature include inguinal-scrotal hernias containing ureter and bladder with post-renal failure or containing ectopic congenital pelvic or transplanted iliac kidney. Our patient is very unusual in that he presented with inguinal herniated, orthotopic, atrophic hydronephrosis with suspicion of congenital ureteropelvic junction obstruction as well as an asymptomatic large intestinal hernia. Reasons for pre-renal acute on chronic renal failure can make it difficult to arrive at a decision of a urological therapy.

RESUMO

BACKGROUND: Radiation-induced cataracts represent a relevant risk to people occupationally exposed to radiation. The annual limit dose for the eye lens was reduced to 20 mSv per year by German legislation (radiation protect law StrlSchG 2017; 2013/59/Euratom) based on recommendation of International Commission on Radiation Protection (2011 ICRP) to avoid radiation-induced cataracts. OBJECTIVES: Is there a risk of exceeding the annual limit dose for the eye lens in routine urological practice without special radiation protection for the head? METHODS: As part of a prospective, monocentric dosimetry study, of 542 different urological, fluoroscopically guided interventions, the eye lens dose was determined using a forehead dosimeter (thermo-luminescence dosemeter TLD, Chipstrate) over a period of 5 months. RESULTS: An average head dose of 0.05 mSv per intervention (max. 0.29 mSv) was found with an average dose area product of 485.33 Gy/cm2. Significant influencing factors for a higher dose were a higher patient body mass index (BMI), a longer operation time, and a higher dose area product. The level of experience of the surgeon showed no significant influence. DISCUSSION: With 400 procedures per year or an average of 2 procedures per working day, the critical annual limit value for the eye lenses or for the risk of radiation-induced cataract would be exceeded without special protective measures. CONCLUSION: Consistently effective radiation protection of the eye lens is essential for daily work in uroradiological interventions. This may require further technical developments.

RESUMO

BACKGROUND: In the context of blunt abdominal trauma, injuries to the urinary tracts often occur, especially in polytrauma patients. Urotrauma is rarely immediately life-threatening but can lead to serious complications and chronic functional limitations during treatment. Therefore early urological involvement is crucial for adequate interdisciplinary treatment. METHODS: The most important facts for the clinical routine on the consultant urological management of urogenital injuries in blunt abdominal trauma are discussed according to the European "EAU guidelines on Urological Trauma" and the German "S3 guidelines on Polytrauma/Treatment of Severely Injured Patients" as well as the relevant literature. RESULTS: Urinary tract injuries can occur even with an initially inconspicuous status and always require explicit exclusion diagnostics by means of contrast medium tomography of the entire urinary tract and, if necessary, by means of urographic and endoscopic examinations. The most common urological intervention is catheterization of the urinary tract which is often required. Less common is urological surgery, which should be coordinated interdisciplinarily with visceral and trauma surgery. More than 90% of vitally threatening kidney injuries (usually up to the American Association for the Surgery of Trauma (AAST) grades 4-5) are now treated by interventional radiology. CONCLUSION: Due to possible complex injury patterns in blunt abdominal trauma, these patients should ideally be directed to (certified) trauma centers with subspecialized or maximum care from the departments of visceral and vascular surgery, trauma surgery, interventional radiology and urology.

RESUMO

The perineal approach for prostate biopsy (PB) is a sterile alternative to conventional transrectal PB. Targeted local anesthesia allows perineal prostate biopsy (pPB) to be performed without general anesthesia. This paper presents the first results after establishing perineal MRI/ultrasound fusion biopsy (pFB) under local anesthesia without standard perioperative antibiotic prophylaxis. For this purpose, 144 patients were included in the study after pFB at the Vivantes Klinikum am Urban. No peri-interventional antibiotic prophylaxis was applied. Peri- and postoperatively, the pain sensation, measured using an analogue pain scale from 0-10, and complications were recorded. The median patient age was 68 and the median prostate-specific antigen (PSA) value 7.07 ng/ml. In all, 49% of the patients received primary PB. The overall detection rate for prostate cancer (PCa) was 71% and for PI-RADS 3, 4 and 5 was 44, 71 and 92%, respectively. The median pain sensation during biopsy was 2. Furthermore, 63% of patients with a transrectal prebiopsy considered this to be more painful and another 20% expressed similar pain levels. Only 1 patient developed a febrile urinary tract infection. The pFB of the prostate under local anesthesia without antibiotic, perioperative prophylaxis is a suitable alternative to the transrectal PB with regard to the detection rate of PCa, the side effect profile and the subjective pain perception of the patients during the intervention.

RESUMO

PURPOSE: To investigate focal therapy using High Intensity Focused Ultrasound (HIFU) for the treatment of localized prostate cancer (CaP), we analyzed the safety and complications of this procedure. METHODS: Patients (pts) eligible for this multicenter prospective cohort study suffered from low to intermediate risk localized CaP with no prior treatment. After tumor identification on multiparametric MRI and in prostate biopsy, the lesions were treated with HIFU observing a safety margin of 8 to 10 mm. Adverse events (AE) after 30 and 90 days, as well as the required interventions were assessed and stratified for treatment localizations. RESULTS: Of the 98 men included in the study in two European centers, 35 (35.7%) experienced AEs in the first 30 days after HIFU intervention with Clavien-Dindo grade ≤ II: 15 pts (15.3%) had a postoperative urinary tract infection and 26 pts (26.5%) a urinary retention. Four pts (4.1%) underwent subsequent intervention (Clavien-Dindo grade IIIa/b). The number of late postoperative complications occurring between 30 and 90 days after intervention was low (2.0%). The highest complication rate was associated with tumors located at the anterior base (50.0%). The inclusion of the urethra in the ablation zone led to AEs in 20 out of 41 cases (48.8%) and represented a significant risk factor for complications within 30 days (odds ratio = 2.53; 95% confidence interval: 1.08-5.96; P = 0.033). CONCLUSIONS: Focal therapy of CaP lesions with a robotic HIFU-probe is safe and renders an acceptable rate of minor early AEs. The inclusion of the urethra in the ablation zone leads to an increase in early complications and should be avoided whenever possible.

RESUMO

The availability of taxane-based chemotherapy and androgen-receptor-targeted agents (ARTAs) have significantly broadened the therapeutic options for patients with metastatic prostate cancer and may also result in longer patient survival. The therapeutic sequence of ARTAs and taxanes may influence outcome and therefore decisions should be made on an individual basis. This article provides guidance for therapeutic decision-making in daily clinical practice by working out criteria that can be used to support individual therapeutic decisions. The focus is on metastatic castration-naive prostate cancer, oligometastatic disease as well as non-metastatic and metastatic castration-resistant prostate cancer.

RESUMO

Focal therapy (FT) should have the same oncological efficacy as whole gland therapy with fewer side effects. Precise diagnosis with PI-RADS v2 standard multiparametric magnetic resonance imaging (MRI) and fusion or template biopsy is a basic prerequisite. Numerous ablation technologies and treatment strategies have been developed, including hemiablation. Treatment success is still inconsistently defined. The only large randomized study available compares one of the procedures to standard therapy. Therefore, even in 2019, FT must still be regarded as experimental and should only be carried out within the context of studies. Follow-up should correspond to active surveillance (AS), including MRI and fusion biopsy. Advantages and disadvantages of each ablation technique should be taken into consideration as well as the suitability of certain regions in the gland. Ideally, an individualized "à la carte" selection of various procedures should be offered. FT is well suited for patients with highly localized cancers at intermediate risk if standard therapies or AS is not possible or has been refused.

RESUMO

Within the BUSTER trial, we analyzed the surgeon's amount of experience and other parameters associated with URS procedures regarding the stone-free rate, complication rate, and operative time. Patient characteristics and surgical details on 307 URS procedures were prospectively documented according to a standardized study protocol at 14 German centers 01-04/2015. Surgeon's experience was correlated to clinical characteristics, and its impact on the stone-free rate, complication rate, and operative time subjected to multivariate analysis. 76 (25%), 66 (21%) and 165 (54%) of 307 URS procedures were carried out by residents, young specialists, and experienced specialists (> 5 years after board certification), respectively. Median stone size was 6 mm, median operative time 35 min. A ureteral stent was placed at the end of 82% of procedures. Stone-free rate and stone-free rate including minimal residual stone fragments (adequate for spontaneous clearance) following URS were 69 and 91%, respectively. No complications were documented during the hospital stays of 89% of patients (Clavien-Dindo grade 0). According to multivariate analysis, experienced specialists achieved a 2.2-fold higher stone-free rate compared to residents (p = 0.038), but used post-URS stenting 2.6-fold more frequently (p = 0.023). Surgeon's experience had no significant impact on the complication rate. We observed no differences in this study's main endpoints, namely the stone-free and complication rates, between residents and young specialists, but experienced specialists' stone-free rate was significantly higher. During this cross-sectional study, 75% of URS procedures were performed by specialists. The experienced specialists' more than two-fold higher stone-free rate compared to residents' justifies ongoing efforts to establish structured URS training programs.

RESUMO

There is an ongoing change of paradigm in the treatment of metastatic prostate cancer (mPC). Taxan-based chemotherapy demonstrated a prolonged survival of patients in several randomized phase III trials. This is true in the situation of metastatic castration-resistent prostate cancer (mCRPC) as well as in the hormone-naïve stage (metastatic castration-naive PC [mCNPC]). In patients with mCNPC, treatment with docetaxel in combination with androgen deprivation therapy (ADT) prolonged the median total survival time by 15 months in comparison to ADT alone. Comparable results were obtained by the endocrine combination treatment with ADT/abiraterone. With the current data in mind it seems to be useful to discuss the value of early combination therapy with ADT/docetaxel or ADT/abiraterone as well as the impact on further treatment options in the mCRPC setting and to define criteria for treatment decisions in clinical practice.

RESUMO

BACKGROUND: The polycomb group (PCG) proteins are epigenetic transcriptional repressors involved in the control of cellular proliferation and oncogenesis. This study aimed at examining whether mRNA tumor levels of the PCG family members BMI1, SUZ12, RING1, and CBX7 relate to histopathological parameters in urothelial carcinomas of the bladder and whether they may provide prognostic information following tumor resection. METHODS: The relative gene expression of BMI1, SUZ12, RING1, and CBX7 was analyzed by real-time RT-PCR in tumor tissue obtained from 93 patients with urothelial carcinoma of the bladder undergoing surgical treatment. Expression data was correlated with pathological variables and outcome. RESULTS: PCG family members BMI1, SUZ12, RING1, and CBX7 are commonly expressed in urothelial carcinomas of the bladder. The relative CBX7 mRNA expression levels gradually decreased from superficial (pTa) to invasive (pT1) and finally to muscle-invasive (> or =pT2) tumors (p = 0.008). Furthermore, CBX7 expression was statistically significantly correlated with tumor grade (p = 0.04). No correlation of mRNA levels with histopathological tumor features or tumor recurrence was observed for the other PCG components investigated. CONCLUSION: Expression levels of CBX7 inversely correlate with the progression of tumor stage and grade in urothelial carcinomas of the bladder, suggesting that downregulation of CBX7 indicates aggressive urothelial carcinoma phenotype.

RESUMO

Neoadjuvant and adjuvant therapeutic strategies are widely employed for a variety of cancer entities. The basic aim and the potential benefit for the patient are to eradicate micrometastases, with the downside being side effects and overtreatment. Neoadjuvant and adjuvant hormone therapy for prostate cancer have been investigated in a number of clinical studies. Based on these studies, the following recommendations can be given: there is currently no indication for neoadjuvant therapy prior to radical prostatectomy. Adjuvant therapy using LHRH analogs for patients with lymph node-positive tumors following radical prostatectomy can be considered but should be weighed against early"biochemical progression triggered" treatment. For locally advanced tumors the same is true (bicalutamide): adjuvant treatment has shown an advantage in clinically progression-free survival; however, no systematic comparison is available with early"biochemical progression triggered" treatment. Before radiotherapy 2 months of neoadjuvant LHRH analog treatment has shown a survival advantage in patients with locally advanced tumors and a low risk of systemic spread (Gleason <7). For high-risk patients, long-term (2-3 years) adjuvant LHRH analog treatment is indicated.

RESUMO

Radical prostatectomy for treatment of prostate cancer is a technically sophisticated operation. Simpler therapies have therefore been developed in the course of decades. The decisive advantage of a radical operation is the chance of a cure with minimal collateral damage. It is the only approach that enables precise tumor staging. The 10-year progression-free survival probability is approximately 85% for a localized tumor with negative resection margins. This high cure rate is unsurpassed by competitive treatment modalities. Nowadays, experienced surgeons achieve excellent functional results (for example, recovery of continence and erectile function) with minimum morbidity. Even in the locally advanced stage, results are very good compared to those obtained with other treatment modalities. Pathological staging enables stratified adjuvant therapy based on concrete information. The overall prognosis can thus be significantly improved.

RESUMO

Although hormone therapy is widely used in the management of prostate cancer, the optimal timing of its initiation remains a matter of debate. Many studies of the last decades have reported a small but significant survival benefit and a clear delay in the development of clinical symptoms after early initiation of therapy. Patients who have localized or locally advanced prostate cancer and are not suitable for curative options like radical prostatectomy or radiotherapy can best be managed by hormone therapy alone, which has already been recognized as the optimal treatment for metastatic disease. On the other hand, long-term hormone treatment will expose the patient to the risk of substantial adverse effects, including muscle wasting, chronic fatigue and osteoporosis. Prognostic and quality-of-life factors also have an impact on the treatment decision, particularly in patients most likely to profit from an extension of the remaining life span. Based on available evidence, early hormone therapy may be recommended for men with poorly differentiated tumors or advanced disease and for those infrequently seen by their physicians. This management can prevent prostate cancer from migrating to the bones, where treatment becomes extremely difficult and cure or even longterm control of the disease is an exception.

RESUMO

The incidence of renal cell carcinoma has been rising for years. At the same time there is an increasing prevalence of chronic renal failure with subsequent higher morbidity and shorter life expectancy in those affected. In the last decades the gold standard has thus shifted from radical to partial nephrectomy or tumor enucleation. A treatment alternative can be advantageous for selected patients with high morbidity and an increased risk of complications in anesthesia or surgery. Active surveillance represents a controlled delay in the initiation of treatment with a curative intention. Percutaneous radiofrequency ablation and laparoscopic cryoablation are currently the most commonly used treatment alternatives. Newer ablation procedures, such as high-intensity focused ultrasound, irreversible electroporation, microwave ablation, stereotactic ablative radiotherapy and high-dose brachytherapy have a high potential in some cases but are still considered experimental for the treatment.

RESUMO

BACKGROUND: The Post-ureteroscopic Lesion Scale (PULS) was designed as a standardized classification system for ureteral lesions after uretero(reno)scopy (URS). This study evaluates its routine use and a possible clinical impact based on a representative patient cohort. MATERIALS AND METHODS: Data of 307 patients in 14 German centers within the BUSTER project were used to test 3 hypotheses (H): PULS score shows a high interrater reliability (IRR) after independent assessment by urologic surgeon and assistance personnel (H1); PULS score is correlated with the frequency of postoperative complications during hospital stay (H2); post-URS stenting of the ureter is associated with higher PULS scores (H3). RESULTS: Median age of patients was 54.4 years (interquartile range [IQR] 44.4-65.8; 65.5% male). Median diameter of index stones was 6 mm (IQR 4-8) with 117 (38.4%) pyelo-caliceal and 188 (61.6%) ureteral stones. Overall, 70 and 82.4% of patients had pre-stenting and post-URS stenting, respectively. Stone-free status was achieved in 68.7% after one URS procedure with a complication rate of 10.8% (mostly grade 1-2 according to Clavien-Dindo). PULS scores 0, 1, 2 and 3 were assessed in 40%, 52.1%, 6.9% and 1% of patients, respectively, when estimated by urologic surgeons. PULS score showed a high IRR between the urologic surgeon and assistance personnel (κ = 0.883, p < 0.001), but was not significantly correlated with complications (ρ = 0.09, p = 0.881). In contrast, a significant positive correlation was found between PULS score and post-URS stenting (ρ = 0.287, p < 0.001). A PULS score of 1 multiplied the likelihood of post-URS stenting by 3.24 (95% confidence interval 1.43-7.34; p = 0.005) as opposed to PULS score 0. CONCLUSIONS: Removal of upper urinary tract stones using URS is safe and efficacious. Real-world data provided by this study confirm a high IRR of the PULS score and its clinical impact on the indication for post-URS stenting. A future prospective randomized trial should evaluate a possible standardization of post-URS stenting based on PULS score assessment.
