RESUMO

BACKGROUND: Diabetic foot disease is associated with significant morbidity and mortality. Patients at high risk of developing diabetic foot disease can reduce their risk, however, by practicing appropriate foot self-care behaviours. Despite this fact, and often despite education regarding appropriate foot care, patients frequently engage in risky foot care practices which place them at risk of foot ulceration. AIM: We aimed to assess knowledge of appropriate foot care behaviours in a cohort of Irish patients at high risk of developing diabetic foot disease attending a multidisciplinary foot clinic, and to assess foot self-care practice. We also aimed to determine predictors for suboptimal self-care behaviour. DESIGN: A questionnaire-based cohort study. METHODS: A multi-aspect questionnaire was designed by the diabetes foot care team, based on the principles of good foot care and the education provided to patients attending the diabetes podiatry clinic. RESULTS: One hundred forty-three participants with high-risk feet completed a questionnaire exploring foot care knowledge and practice. The responses revealed suboptimal foot care knowledge and practice. Participants frequently engaged in risky foot care practices, and were unable to consistently identify appropriate footwear for high-risk feet. Predictors of good foot care included a history of prior ulceration, podiatry attendance, microvascular complications of diabetes, and longer duration of diabetes. CONCLUSION: In this cohort of Irish patients with high-risk feet, foot care knowledge and practice varied widely. Participants frequently engaged in high-risk behaviours despite prior education. Improved strategies to impart diabetic foot care advice to patients with diabetes and high-risk feet are urgently required.

RESUMO

PURPOSE: Optimal follow-up strategies following trimodal treatment for muscle invasive bladder cancer play a crucial role in detecting and managing relapse and side-effects. This article provides a comprehensive summary of the patterns and risk factors of relapse, functional outcomes, and follow-up protocols. METHODS: A systematic literature search on PubMed and review of current guidelines and institutional follow-up protocols after trimodal therapy were conducted. RESULTS: Out of 200 identified publications, 43 studies (28 retrospective, 15 prospective) were selected, encompassing 7447 patients (study sizes from 24 to 728 patients). Recurrence rates in the urinary bladder varied between 14-52%; 3-16% were muscle-invasive while 11-36% were non-muscle invasive. Nodal recurrence occurred at 13-16% and distant metastases at 15-35%. After 5 and 10 years of follow-up, around 60-85% and 45-75% of patients could preserve their bladder, respectively. Various prognostic risk factors associated with relapse and inferior survival were proposed, including higher disease stage (> c/pT2), presence of extensive/multifocal carcinoma in situ (CIS), hydronephrosis, multifocality, histological subtypes, incomplete transurethral resection of bladder tumor (TURBT) and incomplete response to radio-chemotherapy. The analyzed follow-up guidelines varied slightly in terms of the number, timing, and types of investigations, but overall, the recommendations were similar. CONCLUSION: Randomized prospective studies should focus on evaluating the impact of specific follow-up protocols on oncological and functional outcomes following trimodal treatment for muscle-invasive bladder cancer. It is crucial to evaluate personalized adaption of follow-up protocols based on established risk factors, as there is potential for improved patient outcomes and resource allocation.

RESUMO

BACKGROUND: This single-center retrospective study aimed to evaluate the efficacy and toxicity profiles of stereotactic body radiotherapy (SBRT) and surgical resection in patients with adrenal metastases originating from solid tumors. METHODS/MATERIALS: Patients with advanced tumor conditions or comorbidities typically received SBRT, whereas those considered physically fit underwent standard surgical treatment. Endpoints included local control (LC), progression free survival (PFS), overall survival (OS), and complication rates (CR). RESULTS: 41 patients with 48 adrenal metastases were included, with 27 (65.9%) patients receiving SBRT and 14 (34.1%) patients undergoing adrenalectomy. One- and two-year LC values were 100% for both periods after adrenalectomy, and 70.0% and 52.5% after SBRT (p = 0.001). PFS showed values of 40.2% and 32.1% at one and two years after adrenalectomy and of 10.6% for both periods after SBRT (p = 0.223). OS was 83.3% both one and two years after surgery and 67.0% and 40.2% after SBRT (p = 0.031). There was no statistically significant difference between the two groups regarding acute complications (p = 0.123). CONCLUSION: Despite potential confounders, adrenalectomy exhibited statistically significant superior LC and OS compared to SBRT in managing adrenal metastases, while both treatment methods displayed acceptable toxicity profiles. However, patient selection bias must be taken into account when directly comparing the two therapy modalities. Nevertheless, the study provides new and important results for the scientific and medical communities regarding oncological outcomes after SBRT or surgical resection of adrenal metastases.

RESUMO

OBJECTIVE: To report on the surgical safety and quality of pelvic lymph node dissection (PLND) in patients treated with radical cystectomy (RC) and PLND for muscle-invasive bladder cancer (MIBC) after neoadjuvant chemo-immunotherapy. PATIENTS AND METHODS: The Swiss Group for Clinical Cancer Research (SAKK) 06/17 was an open-label single-arm phase II trial including 61 cisplatin-fit patients with clinical stage (c)T2-T4a cN0-1 operable urothelial MIBC or upper urinary tract cancer. Patients received neoadjuvant cisplatin/gemcitabine and durvalumab followed by surgery. Prospective quality assessment of surgeries was performed via central review of intraoperative photographs. Postoperative complications were assessed using the Clavien-Dindo Classification. Data were analysed descriptively. RESULTS: A total of 50 patients received RC and PLND. All patients received neoadjuvant chemo-immunotherapy. The median (interquartile range) number of lymph nodes removed was 29 (23-38). No intraoperative complications were registered. Grade ≥III postoperative complications were reported in 12 patients (24%). Complete nodal dissection (100%) was performed at the level of the obturator fossa (bilaterally) and of the left external iliac region; in 49 patients (98%) at the internal iliac region and at the right external iliac region; in 39 (78%) and 38 (76%) patients at the right and left presacral level, respectively. CONCLUSION: This study supports the surgical safety of RC and PLND following neoadjuvant chemo-immunotherapy in patients with MIBC. The extent and completeness of protocol-defined PLND varies between patients, highlighting the need to communicate and monitor the surgical template.

RESUMO

PURPOSE: Accurate prediction of extraprostatic extension (EPE) is pivotal for surgical planning. Herein, we aimed to provide an updated model for predicting EPE among patients diagnosed with MRI-targeted biopsy. MATERIALS AND METHODS: We analyzed a multi-institutional dataset of men with clinically localized prostate cancer diagnosed by MRI-targeted biopsy and subsequently underwent prostatectomy. To develop a side-specific predictive model, we considered the prostatic lobes separately. A multivariable logistic regression analysis was fitted to predict side-specific EPE. The decision curve analysis was used to evaluate the net clinical benefit. Finally, a regression tree was employed to identify three risk categories to assist urologists in selecting candidates for nerve-sparing, incremental nerve sparing and non-nerve-sparing surgery. RESULTS: Overall, data from 3169 hemi-prostates were considered, after the exclusion of prostatic lobes with no biopsy-documented tumor. EPE was present on final pathology in 1,094 (34%) cases. Among these, MRI was able to predict EPE correctly in 568 (52%) cases. A model including PSA, maximum diameter of the index lesion, presence of EPE on MRI, highest ISUP grade in the ipsilateral hemi-prostate, and percentage of positive cores in the ipsilateral hemi-prostate achieved an AUC of 81% after internal validation. Overall, 566, 577, and 2,026 observations fell in the low-, intermediate- and high-risk groups for EPE, as identified by the regression tree. The EPE rate across the groups was: 5.1%, 14.9%, and 48% for the low-, intermediate- and high-risk group, respectively. CONCLUSION: In this study we present an update of the first side-specific MRI-based nomogram for the prediction of extraprostatic extension together with updated risk categories to help clinicians in deciding on the best approach to nerve-preservation.

RESUMO

BACKGROUND: Positive surgical margins (PSMs) are frequent in patients undergoing radical prostatectomy (RP). The impact of PSMs on cancer-specific (CSM) and overall (OM) mortality has not yet been proved definitively. OBJECTIVE: To evaluate whether the presence and the features of PSMs were associated with CSM and OM in patients who underwent robotic-assisted RP. DESIGN, SETTING, AND PARTICIPANTS: A cohort of 8141 patients underwent robotic-assisted RP with >10 yr of follow-up. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Cox multivariable analyses assessed the impact of margin status (positive vs negative) and PSM features (negative vs <3 mm vs >3 mm vs multifocal) on the risk of CSM, OM, and biochemical recurrence (BCR) after adjusting for potential confounders. We repeated our analyses after stratifying patients according to clinical (Cancer of the Prostate Risk Assessment [CAPRA] categories) and pathological characteristics (adverse: pT 3-4 and/or grade group [GG] 4-5 and/or pN1 and/or prostate-specific antigen [PSA] persistence). RESULTS AND LIMITATIONS: PSMs were found in 1348 patients (16%). Among these, 48 (3.6%) patients had multifocal PSMs. Overall, 1550 men experienced BCR and 898 men died, including 130 for prostate cancer. At Cox multivariable analyses, PSMs were associated with CSM in patients with adverse clinical (Intermediate risk: hazard ratio [HR]: 1.71, p = 0.048; high risk: HR: 2.20, p = 0.009) and pathological (HR: 1.79, p = 0.005) characteristics. Only multifocal PSMs were associated with CSM and OM in the whole population (HR for CSM: 4.68, p < 0.001; HR for OM: 1.82, p = 0.037) and in patients with adverse clinical (intermediate risk: HR for CSM: 7.26, p = 0.006; high risk: HR for CSM: 9.26, p < 0.001; HR for OM: 2.97, p = 0.006) and pathological (HR for CSM: 9.50, p < 0.001; HR for OM: 2.59, p = 0.001) characteristics. Potential limitations include a selection bias and a lack of information on the Gleason score at PSM location. CONCLUSIONS: We did not find an association between unifocal PSMs and mortality. Conversely, our results underscore the importance of avoiding multifocal PSMs in patients with adverse clinical (intermediate- and high-risk CAPRA score) and pathological (GG ≥4, pT ≥3, pN1, or PSA persistence) characteristics, to enhance overall survival and reduce CSM. PATIENT SUMMARY: In this study, we evaluated whether the presence and the characteristics of positive surgical margins were associated with mortality in patients who underwent robotic-assisted radical prostatectomy. We found that the presence of positive surgical margins, particularly multifocal margins, was associated with mortality only in patients with adverse clinical and pathological characteristics.

RESUMO

Osteoblastoma is a benign bone tumor that can spread aggressively and is commonly found in the spine and long bones. When present in other areas of the body, it can be difficult to diagnose. While this tumor is rarely found in the hand, in reported cases, it typically presents with pain. Treatment is usually curettage and marginal excision. We report a rare case of osteoblastoma in the fifth proximal phalanx of the left hand in a 14-year-old right-handed female, presenting as a painless, progressively growing mass with associated flexion contracture over a seven-month period, with no history of trauma. An excision biopsy with curettage was performed, and histopathologic examination confirmed the diagnosis of osteoblastoma. This is a rare case of osteoblastoma of the proximal phalanx presenting as a painless mass in the finger with a progressive flexion contracture. Histopathologic examination is important in diagnosing osteoblastoma to determine the appropriate treatment and surgery. Post-operatively, close monitoring is important due to the high recurrence rates in these tumors.

RESUMO

BACKGROUND: Acute kidney injury (AKI) after robot-assisted partial nephrectomy (RAPN) is a robust surrogate for chronic kidney disease. The objective of this study was to evaluate the association of ischemia type and duration during RAPN with postoperative AKI. MATERIALS AND METHODS: We reviewed all patients who underwent RAPN at our institution since 2011. The ischemia types were warm ischemia (WI), selective artery clamping (SAC), and zero ischemia (ZI). AKI was defined according to the Risk Injury Failure Loss End-Stage (RIFLE) criteria. We calculated ischemia time thresholds for WI and SAC using the Youden and Liu indices. Logistic regression and decision curve analyses were assessed to examine the association with AKI. RESULTS: Overall, 154 patients met the inclusion criteria. Among all RAPNs, 90 (58.4%), 43 (28.0%), and 21 (13.6%) were performed with WI, SAC, and ZI, respectively. Thirty-three (21.4%) patients experienced postoperative AKI. We extrapolated ischemia time thresholds of 17 min for WI and 29 min for SAC associated with the occurrence of postoperative AKI. Multivariable logistic regression analyses revealed that WIT ≤ 17 min (odds ratio [OR] 0.1, p < 0.001), SAC ≤ 29 min (OR 0.12, p = 0.002), and ZI (OR 0.1, p = 0.035) significantly reduced the risk of postoperative AKI. CONCLUSIONS: Our results confirm the commonly accepted 20 min threshold for WI time, suggest less than 30 min ischemia time when using SAC, and support a ZI approach if safely performable to reduce the risk of postoperative AKI. Selecting an appropriate ischemia type for patients undergoing RAPN can improve short- and long-term functional kidney outcomes.

RESUMO

The aim of this study was to demonstrate the correlation between ADC values and the ADC/PSAD ratio for potentially malignant prostate lesions classified into ISUP grades and to determine threshold values to differentiate benign lesions (noPCa), clinically insignificant (nsPCa) and clinically significant prostate cancer (csPCa). We enrolled a total of 403 patients with 468 prostate lesions, of which 46 patients with 50 lesions were excluded for different reasons. Therefore, 357 patients with a total of 418 prostate lesions remained for the final evaluation. For all lesions, ADC values were measured; they demonstrated a negative correlation with ISUP grades (p < 0.001), with a significant difference between csPCa and a combined group of nsPCa and noPCa (ns-noPCa, p < 0.001). The same was true for the ADC/PSAD ratio, but only the ADC/PSAD ratio proved to be a significant discriminator between nsPCa and noPCa (p = 0.0051). Using the calculated threshold values, up to 31.6% of biopsies could have been avoided. Furthermore, the ADC/PSAD ratio, with the ability to distinguish between nsPCa and noPCa, offers possible active surveillance without prior biopsy.

RESUMO

Background: Robot-assisted repair of benign ureteroenteric anastomotic strictures (UAS) provides an alternative to the open approach. We aimed to report short-, medium-, and long-term outcomes for robotic repair of benign UAS, and to provide a detailed video demonstration of critical operative techniques in performing this procedure robotically. Materials and Methods: Between January 2013 and September 2022, 31 patients from seven institutions who previously underwent radical cystectomy and subsequently developed UAS underwent robotic repair of UAS. Perioperative variables were prospectively collected, and postoperative outcomes were assessed. The surgery starts with a lysis of adhesions after previous surgery. Ureters are dissected, and the level of the stricture is identified. The ureter is then divided, and the stricture is resected. Finally, the ureter is spatulated and reimplanted with Nesbit technique after stenting with Double-J stents. In cases where both ureters show strictures, Wallace technique for reimplantation can be applied. Results: After robotic or open cystectomy, 31 patients had a total of 43 UAS at a median (interquartile range) follow-up of 21 (9-43) months. Median stricture length was 2.0 (1.0-3.25) cm, operative duration was 141 (121-232) minutes, estimated blood loss was 100 (50-150) mL, and length of hospital stay was 5 (3-9) days. One (3.2%) case was converted to open and one (3.2%) intraoperative complication occurred. Seven (22.6%) patients experienced postoperative complications, including four (12.9%) Clavien-Dindo grade 3 complications. No Clavien-Dindo grade 4 or 5 complications occurred. Stricture recurrence occurred in 2 (6.5%) patients. Conclusions: These results demonstrate that robotic repair of UAS is feasible and effective approach with outcomes in line with prior open series. Patient Consent Statement: Authors have received and archived patient consent for video recording and publication in advance of video recording of procedure.

RESUMO

BACKGROUND: Evidence on long-term oncological efficacy is available only for open radical prostatectomy but remains scarce for robot-assisted radical prostatectomy (RARP). OBJECTIVE: To validate the long-term survival rates after RARP and provide stratified outcomes based on contemporary prostate cancer (PCa) risk-stratification tools. DESIGN, SETTING, AND PARTICIPANTS: A retrospective analysis of the European Association of Urology (EAU) Robotic Urology Section Scientific Working Group international multicenter database for RARP was performed. Patients who underwent RARP at seven pioneer robotic urology programs in Europe and the USA between 2002 and 2012 were included. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary outcomes were PCa-specific mortality and all-cause mortality. The probability of cancer-specific survival (CSS) was estimated with the competing risks method, and the probability of overall survival (OS) was estimated with the Kaplan-Meier method. RESULTS AND LIMITATIONS: A total of 9876 patients who underwent RARP between 2002 and 2012 were included. Within follow-up, 1071 deaths occurred and 159 were due to PCa. At 15 yr of follow-up, CSS and OS were 97.6% (97.2%, 98.0%) and 85.5% (84.6%, 86.4%), respectively. Stratified analyses based on EAU risk groups at diagnosis and pT stage showed favorable survival rates, with low-risk (n = 4601, 46.6%), intermediate-risk (n = 4056, 41.1%), and high-risk (n = 1219, 12.3%) patients demonstrating CSS rates of 99%, 98%, and 90% at 15 yr, respectively. Notably, patients with pT3a disease had similar survival outcomes to those with pT2 disease, with worse CSS in patients with pT3b PCa (98.9% vs 97.4% vs 86.5%). Multivariable analyses identified age, prostate-specific antigen, biopsy Gleason grade group, clinical T stage, and treatment year as independent predictors of worse oncological outcomes. CONCLUSIONS: Our multicenter study with long-term follow-up confirms favorable survival outcomes after RARP for localized PCa. Patients with low- and intermediate-risk disease face a higher risk of mortality from causes other than PCa. On the contrary, high-risk patients have a significantly higher risk of PCa-specific mortality. PATIENT SUMMARY: In the present study, we reported the outcomes of patients with prostate cancer (PCa) who underwent robot-assisted radical prostatectomy between 10 and 20 yr ago, and we found a very low probability of dying from PCa in patients with low- and intermediate-risk PCa.

RESUMO

PURPOSE: The integration of immunotherapy in the perioperative setting of muscle-invasive urothelial carcinoma (MIUC) appears promising. SAKK 06/17 investigated the addition of neoadjuvant durvalumab to gemcitabine/cisplatin (GC) chemotherapy followed by radical surgery and adjuvant checkpoint inhibition with durvalumab. PATIENTS AND METHODS: SAKK 06/17 was an investigator-initiated, open-label, single-arm phase II study including cisplatin-fit patients with stage cT2-T4a cN0-1 operable MIUC. Four cycles of neoadjuvant GC in combination with four cycles of durvalumab (start with GC cycle 2) were administered, followed by radical surgery. Adjuvant durvalumab was given for 10 cycles. The primary end point was event-free survival (EFS) at 2 years. RESULTS: Sixty one patients were accrued at 12 sites. The full analysis set consisted of 57 patients, 54 (95%) had bladder cancer. Median follow-up was 40 months. The primary end point was met, with EFS at 2 years of 76% (one-sided 90% CI [lower bound], 67%; two-sided 95% CI, 62 to 85). EFS at 3 years was 73% (95% CI, 59 to 83). Complete pathologic response in resected patients (N = 52) was achieved in 17 patients (33%), and 31 (60%) had pathologic response

RESUMO

PURPOSE: Bilateral extended pelvic lymph node dissection at the time of radical prostatectomy is the current standard of care if pelvic lymph node dissection is indicated; often, however, pelvic lymph node dissection is performed in pN0 disease. With the more accurate staging achieved with magnetic resonance imaging-targeted biopsies for prostate cancer diagnosis, the indication for bilateral extended pelvic lymph node dissection may be revised. We aimed to assess the feasibility of unilateral extended pelvic lymph node dissection in the era of modern prostate cancer imaging. MATERIALS AND METHODS: We analyzed a multi-institutional data set of men with cN0 disease diagnosed by magnetic resonance imaging-targeted biopsy who underwent prostatectomy and bilateral extended pelvic lymph node dissection. The outcome of the study was lymph node invasion contralateral to the prostatic lobe with worse disease features, ie, dominant lobe. Logistic regression to predict lymph node invasion contralateral to the dominant lobe was generated and internally validated. RESULTS: Overall, data from 2,253 patients were considered. Lymph node invasion was documented in 302 (13%) patients; 83 (4%) patients had lymph node invasion contralateral to the dominant prostatic lobe. A model including prostate-specific antigen, maximum diameter of the index lesion, seminal vesicle invasion on magnetic resonance imaging, International Society of Urological Pathology grade in the nondominant side, and percentage of positive cores in the nondominant side achieved an area under the curve of 84% after internal validation. With a cutoff of contralateral lymph node invasion of 1%, 602 (27%) contralateral pelvic lymph node dissections would be omitted with only 1 (1.2%) lymph node invasion missed. CONCLUSIONS: Pelvic lymph node dissection could be omitted contralateral to the prostate lobe with worse disease features in selected patients. We propose a model that can help avoid contralateral pelvic lymph node dissection in almost one-third of cases.

RESUMO

BACKGROUND: Little is known regarding functional outcomes after robot-assisted radical cystectomy (RARC) and intracorporeal neobladder (ICNB) reconstruction. OBJECTIVE: To report on urinary continence (UC) and erectile function (EF) at 12 mo after RARC and ICNB reconstruction and investigate predictors of these outcomes. DESIGN, SETTING, AND PARTICIPANTS: We used data from a multi-institutional database of patients who underwent RARC and ICNB reconstruction for bladder cancer. SURGICAL PROCEDURE: The cystoprostatectomy sensu stricto followed the conventional steps. ICNB reconstruction was performed at the physician's discretion according to the Studer/Wiklund, S pouch, Gaston, vescica ileale Padovana, or Hautmann technique. The techniques are detailed in the video accompanying the article. MEASUREMENTS: The outcomes measured were UC and EF at 12 mo. RESULTS AND LIMITATIONS: A total of 732 male patients were identified with a median age at diagnosis of 64 yr (interquartile range 58-70). The ICNB reconstruction technique was Studer/Wiklund in 74%, S pouch in 1.5%, Gaston in 19%, vescica ileale Padovana in 1.5%, and Hautmann in 4% of cases. The 12-mo UC rate was 86% for daytime and 66% for nighttime continence, including patients who reported the use of a safety pad (20% and 32%, respectively). The 12-mo EF rate was 55%, including men who reported potency with the aid of phosphodiesterase type 5 inhibitors (24%). After adjusting for potential confounders, neobladder type was not associated with UC. Unilateral nerve-sparing (odds ratio [OR] 3.85, 95% confidence interval [CI] 1.88-7.85; p < 0.001) and bilateral nerve-sparing (OR 6.25, 95% CI 3.55-11.0; p < 0.001), were positively associated with EF, whereas age (OR 0.93, 95% CI 0.91-0.95; p < 0.001) and an American Society of Anesthesiologists score of 3 (OR 0.46, 95% CI 0.25-0.89; p < 0.02) were inversely associated with EF. CONCLUSIONS: RARC and ICNB reconstruction are generally associated with good functional outcomes in terms of UC. EF is highly affected by the degree of nerve preservation, age, and comorbidities. PATIENT SUMMARY: We investigated functional outcomes after robot-assisted removal of the bladder in terms of urinary continence and erectile function. We found that, in general, patients have relatively good functional outcomes at 12 months after surgery.

RESUMO

Robot-assisted Simple Prostatectomy (RASP) Abstract: Surgical treatment of large adenomas of the prostate (> 80g) in men suffering from symptomatic prostate hyperplasia is challenging. Transurethral resection of the prostate (TUR-P), known as the operative gold standard, is not a safe option in large adenomas due to prolonged resection time and the consecutive increased complication rate. For decades, large adenomas were surgically treated by open enucleation. Although the procedure has still its role in surgical treatment of large glands, the perioperative morbidity and complications can be severe. In view of this fact, several new and minimal invasive techniques such as transurethral procedures, mainly using laser technologies (Holmiun-Laser Enucleation, HoLEP and KTP-Laser vaporization, Greenlight™ Laser), have been invented. In addition, the traditional open enucleation of the prostate was performed and evaluated by using conventional laparoscopy and finally by robot-assisted laparoscopy. Meanwhile robot-assisted simple prostatectomy (RASP) and especially its modification with an extraperitoneal extravesical access and intraprostatic reconstruction of the prostatic urethra in order to exclude the prostatic wound bed from the urinary tract with consecutive lower perioperative complication rates are well established procedures to treat large adenomas.

RESUMO

OBJECTIVE: To report the technique and preliminary results for extraperitoneal robot-assisted laparoscopic YV-plasty (RAYV) for refractory bladder neck stenosis (BNS) and vesicoureteral anastomosis stenosis (VUAS). MATERIALS AND METHODS: Included were patients with recurrent BNS and VUAS who underwent RAYV at our institution. Primary outcome was short and intermediate-term functional results measured with urinary peak flow (Qmax), post-void residual urine (PVR) as well as quality of life assessment with the international prostate symptom score (IPSS) and short form health survey (SF-8). Short- and intermediate-term follow-up periods were defined as 1-6 months and 6-24 months, respectively. Secondary, all patients were reviewed for etiology as well as perioperative data. Treatment success was defined by absence of further treatment and/or need for intermittent or permanent catheterization. RESULTS: Between March 2016 and October 2020 a total of 30 patients with a median age of 70.8 (64-77) years underwent RAYV with a median follow-up of 27 months. Median operative time (skin-skin) was 131 (112-145) minutes. The transurethral indwelling catheter was removed after 10 (5 - 16) days. There were no intraoperative complications but 2 postoperative major complications Clavien-Dindo IIIa and IV, respectively. Short- and intermediate-term results revealed significant improvement of IPS score from 17 (11-24) points to 11 (6-13) points and 6 (3-9) points, respectively. Further PVR decreased from 90 (5-302) mL to 0 (0-30) mL and 0 (0-90) mL, respectively, and Qmax increased from 7.4 mL/s to 13 (8-16) mL/s and 17 (12-4) mL/s, respectively. Improvement of SF-8 did not reach significance. A total of 5/30 (16.7%) patients had a treatment failure after 24 months whereof 2 had a re-stricture. CONCLUSION: RAVY-Plasty for recurrent bladder neck stenosis is a safe and effective procedure with good functional short- and intermediate-term outcome.

RESUMO

Background: mpMRI assesses prostate lesions through their PI-RADS score. The primary goal of this prospective study was to demonstrate the correlation of PI-RADS v2 score and the volume of a lesion with the presence and clinical significance of prostate cancer (PCa). The secondary goal was to determine the extent of additionally PCa in inconspicuous areas. Methods: All 157 patients underwent a perineal MRI/TRUS-fusion prostate biopsy. Targeted biopsies as well as a systematic biopsy were performed. The presence of PCa in the probes was specified by the ISUP grading system. Results: In total, 258 lesions were biopsied. Of the PI-RADS 3 lesions, 24% were neoplastic. This was also true for 36.9% of the PI-RADS 4 lesions and for 59.5% of the PI-RADS 5 lesions. Correlation between ISUP grades and lesion volume was significant (p < 0.01). In the non-suspicious mpMRI areas carcinoma was revealed in 19.7% of the patients. Conclusions: The study shows that the PI-RADS v2 score and the lesion volume correlate with the presence and clinical significance of PCa. However, there are two major points to consider: First, there is a high number of false positive findings. Second, inconspicuous mpMRI areas revealed PCa.
