Evaluation of the effect of 100U of Onabotulinum toxin A on detrusor contractility in women with idiopathic OAB: A multicentre prospective study.

AIMS: Intradetrusor injection of Onabotulinum Toxin A (BTX-A) is a third-line treatment for overactive bladder (OAB). Voiding dysfunction and the need for intermittent catheterization are potential complications, consequent to bladder contractility (BC) decrement. Primary aim: to evaluate BC variation after BTX-A detrusor injection in women with idiopathic OAB. METHODS: A prospective multi-institutional observational study was conducted. Medical history, bladder diary, 24-h pad test, and invasive urodynamic parameters were recorded before and 4-6 weeks after BTX-A 100U administration. BC was measured as Modified Projected Isovolumetric Pressure (PIP1), that is, maximum flow rate (Qmax) + detrusor pressure at Qmax (PdetQmax). Continuous variables were expressed as median and interquartile range. We compared continuous variables using Wilcoxon test and proportions between two times with Fisher exact test. RESULTS: No changes in PIP1 were observed (p > 0.05) in 45 women enrolled between January 2018 and September 2019. Median age was 54.6 years. At baseline, 91.1% had urge urinary incontinence, with 4.9 ± 2.6 daily pads used and a 24-h pad test of 205.4 ± 70.8 g. Baseline detrusor contractility was normal in all the patients. Postoperatively, an improvement in the 24-h pad test (p < 0.01), daily voids (p < 0.01), and nocturia (p < 0.01) occurred. Urodynamics pointed out a significant reduction of detrusor overactivity rate (p < 0.01) and an increase of median maximum cystometric capacity (p < 0.01). No difference was observed in median Qmax (p > 0.05), PdetQmax (p > 0.05), and PVR (p > 0.05). No patient needed postoperative catheterization. CONCLUSIONS: The current series provides evidence that detrusor injection of botulinum toxin is an effective option for treating OAB, without causing voiding dysfunction and BC impairment.

Athermal versus ultrasonic nerve-sparing laparoscopic radical prostatectomy: a comparison of functional and oncological outcomes.

PURPOSE: Many urologists emphasize the concept of heat-related damage suggesting the avoidance of any energy to perform nerve-sparing radical prostatectomy. At our institution, both athermal and ultrasonic dissection have been used over the last years to perform a nerve-sparing laparoscopic radical prostatectomy (NSLRP). In this study, we compare functional and oncological outcomes of the two procedures. METHODS: All charts from patients undergoing NSLRP between January 2009 and June 2015 were reviewed. The International Index of Erectile Function (IIEF-5) was recorded preoperatively and 3, 12 and 24 months after surgery; continence was recorded at 3 and 12 months; PSA was recorded at last follow-up. Uni- and multivariate analyses were performed to assess the association of variables with functional and oncological outcomes. RESULTS: Ultrasonic NSLRP was used for 120 patients, while athermal NSLRP on 111. The impact of the cutting technique on erection recovery was different at 3 months, favoring athermal dissection (p = 0.002); however, significance was lost at 12 (p = 0.09) and 24 (p = 0.14) months. Continence recovery was comparable at 3 (p = 0.1) and 12 (p = 0.2) months; the rate of positive surgical margins and PSA recurrence were also similar (p = 0.2 and p = 0.06, respectively). At univariate analysis, age, Gleason sum, nerve-sparing laterality, and extension (intra- vs interfascial) were associated with overall erection recovery; only age and nerve-sparing laterality were independent predictors. Age and preoperative TRUS prostate volume were associated with continence recovery, both at uni- and multivariate analysis. CONCLUSIONS: The use of an ultrasonic device compared to athermal dissection during NSLRP does not affect long-term potency, nor continence and early biochemical recurrence.

Robotic radical perineal prostatectomy: tradition and evolution in the robotic era.

PURPOSE OF REVIEW: To provide an updated review of robotic radical perineal prostatectomy (r-RPP) with emphasis on the recent advances in terms of surgical technique, outcomes, and new robotic platforms. RECENT FINDING: The technological innovations in the urological field have been applied to radical prostatectomy with the aim of preserving important anatomical structures and reduce patients' morbidity and mortality. In recent years, robotic surgery contributed to resurge radical perineal prostatectomy. In 2014, the Cleveland Clinic group was the first to demonstrate the utility of a robotic approach in RPP. To date, the majority of the reported studies showed that r-RPP has noninferior perioperative, short-term oncological, and functional outcomes compared with the traditional robot-assisted radical prostatectomy (RARP). Given these benefits, r-RPP is a promising approach in selected patients, such as obese ones. Moreover, robotic perineal pelvic lymph node dissection performed through the same incision of r-RPP and the new Single-Port (SP) Robotic System represent further steps towards the overcoming of some intrinsic limitation of this surgical approach making this technique suitable for a larger number of patients with prostatic cancer. SUMMARY: Overall, r-RPP represents a reliable and effective novel surgical technique. However, more studies with long-term follow-up are needed to clarify the advantages over RARP.

Shear Wave Elastographic Study of the Myotendinous Junction of the Medial Gastrocnemius: Normal Patterns and Dynamic Evaluation.

OBJECTIVES: The myotendinous junction (MTJ) represents a specialized anatomic region through which the contractile strength is transmitted from the muscle to the tendon. The integrity of this region is essential to permit force transmission and to optimize energy expenditure during walking, running, and globally for human movement. We evaluated the MTJ with shear wave elastography to assess its elasticity variation during a functional test. METHODS: Forty professional soccer players were enrolled in the study. Shear wave elastography was performed at the level of the medial gastrocnemius MTJ both in a resting position and during a standing calf rise position to assess functional contraction. RESULTS: All 40 participants were male, aged between 18 and 38 years (mean age, 25 years). The results of the elastographic study showed mean stiffness values ± SD of 4.19 ± 0.86 m/s for the right medial gastrocnemius and 4.20 ± 0.87 m/s for the left medial gastrocnemius with the muscle relaxed. During contraction, the stiffness values were 8.33 ± 0.5 m/s for the right medial gastrocnemius and 8.30 ± 0.48 m/s for the left medial gastrocnemius. CONCLUSIONS: Our study showed an increase of stiffness at the level of the MTJ during muscle contraction. This result is in line with the physiologic stiffening of the MTJ to resist the high level of force applied during muscle contraction. Shear wave elastography could be a useful method to assess the characteristics of the MTJ under both physiologic and pathologic conditions.

Quantitative Elastosonography of the Myotendinous Junction: Normal Behavior and Correlation With a Standard Measurement System During Functional Tests.

OBJECTIVES: In recent years, an increasing need to use imaging to assess normal and adaptive muscle function, in addition to its anatomy and structure, has emerged. We evaluated the myotendinous junction's elastosonographic behavior in light of the most recent literature on its physiologic behavior. The elastosonographic studies were compared with the results obtained from a standard measurement system to ensure a correlation with maximal muscle contraction. METHODS: Nineteen male professional soccer players were assessed during functional tests. The participants performed 5 repetitions at 60°/s to assess muscle strength and 3 repetitions at 30°/s to assess the maximum force peak of thigh muscles. The participants were monitored by a strength-power measurement system and an ultrasound machine equipped with multifrequency (18-6-MHz) linear array transducers. RESULTS: The 19 soccer players were aged between 19 and 34 years (mean age, 28 years). For the right rectus femoris, the results of the elastosonographic studies showed a mean elasticity value ± SD of 30.75% ± 10.05% with the muscle relaxed and a value of 13.75% ± 8.44% during contraction (mean decrease, 17.00% ± 11.71%). Elasticity values were 36.48% ± 8.39% before contraction and 8.77% ± 6.55% during contraction of the left rectus femoris muscle (mean decrease, 27.71% ± 11.95%). For 30° eccentric contraction of the left leg, correlation with the standard measurement system showed Pearson r values of -0.53 and -0.51 when comparing force peak and mean work, respectively, with elasticity values. CONCLUSIONS: Our study shows that strain elastosonographic quantification of muscle elasticity seems to match the expected physiologic and biomechanical behavior of the myotendinous junction.

Femoro-acetabular impingement: what the general radiologist should know.

Femoro-acetabular impingement (FAI) is a common condition in young active subjects, which can lead to the development of early osteoarthritis if not correctly diagnosed. Imaging evaluation of FAI, mainly based on plain film and magnetic resonance evaluation, must be performed according to precise guidelines and is fundamental for reaching a final diagnosis. The purpose of this paper is to provide a clinical and radiological overview of FAI by describing the most common clinical tests, the imaging techniques used in the diagnosis, and the main radiological signs that may be encountered.

Intermediate-term oncological and functional outcomes in prostate cancer patients treated with perineal robot-assisted radical prostatectomy: A single center analysis.

Objective: In the last 10 years, robotic platforms allowed to resume of some alternative surgical approaches, including perineal robot-assisted radical prostatectomy (p-RARP). Herein, we present in detail the oncological and functional outcomes of patients who underwent p-RARP with a median follow-up of 30 months. Methods: Patients presenting low- or intermediate-risk prostate cancer and prostate volume up to 60 mL who underwent p-RARP between November 2018 and November 2022 were selected. Baseline, intraoperative, pathological, and postoperative data were collected and then analyzed. Results: Thirty-seven p-RARP cases were included. Such patients presented mean age of 62 years and a mean Charlson comorbidity index of 4. Body mass index of ≥25 kg/m2 was reported by 24 (64.9%) patients, as well as 7 (18.9%) patients reported a past surgical history. Mean prostate volume and median prostate-specific antigen were 41 mL and 6.2 ng/mL, respectively. The median operative time was 242 min. The positive surgical margin rate was 45.9%. In terms of postoperative complications, 10 patients reported complications with any grade; however, a single case (2.7%) of major (Clavien-Dindo grade ≥3) complication was observed. No patient with biochemical recurrence or distant metastasis was reported at 2 years of follow-up. Recovery of continence rates were 67.6%, 75.7%, and 92.9%, at 6 months, 12 months, and 24 months after surgery, respectively. Conclusion: p-RARP is a challenging but safe minimally invasive approach for selected patients with prostate cancer suitable for radical prostatectomy, showing outstanding functional recovery. Despite positive surgical margin rates being relatively high, no cases of biochemical recurrence or distant metastasis were reported after a median follow-up of 30 months.

Three years outcomes of transperineal laser ablation of the prostate.

BACKGROUND: Ultra-minimally Invasive Surgical Techniques (uMISTs) play an increasingly significant role in treating benign prostatic obstruction (BPO) as an alternative to both medical therapy and surgery. Transperineal laser ablation of the prostate (TPLA) is an uMIST that has shown its efficacy in symptom relief and improvement of urodynamic parameters while sparing ejaculatory function and having a low risk of complications. This is the 3-year follow-up of a pilot study on TPLA. METHODS: TPLA was performed using the SoracteLite™ system. It consists of ablating prostate tissue through a diode laser, eventually causing prostate volume reduction. We recorded International Prostate Symptom Score (IPSS), uroflowmetry parameters, the Male Sexual Health Questionnaire (MSHQ-EjD), and prostate volume at baseline and after 3 years. The Wilcoxon Test was employed to compare continuous variables. RESULTS: Twenty men completed a 3-year follow-up after TPLA. The median prostate volume was 41.5 mL (IQR: 40.0-54.3). Preoperative median IPSS, Qmax, and MSHQ-EjD were 18 (IQR: 16-21), 8.8 mL/s (IQR: 7.8-10.8), and 4 (IQR: 3-8). TPLA showed significant improvement in IPSS (-37.2%; P<0.01) and Qmax (45.8%; P<0.01); median MSHQ-EjD improvement was by 60% (P<0.01) and median prostate volume reduction was by -20.4% (P<0.01). CONCLUSIONS: This analysis shows that TPLA maintains satisfactory results within 3 years. Therefore, TPLA confirms its role in the treatment of patients unsatisfied or intolerant to oral therapies but not eligible for surgery to avoid impact on sexual function or due to anesthesiologic contraindications.

Are Football Players More Prone to Muscle Injury after COVID-19 Infection? The "Italian Injury Study" during the Serie a Championship.

INTRODUCTION: Football was the first sport to resume competitions after the coronavirus disease 2019 (COVID-19) lockdown and promptly the hypothesis was raised of a potential relationship between the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and musculoskeletal injuries in athletes. This study aimed to confirm the association between SARS-CoV-2 infection and muscle strain injury in a large population of elite football players and to investigate if the COVID-19 severity level could affect the risk of injury. METHODS: A retrospective cohort study involving 15 Italian professional male football teams was performed during the Italian Serie A 2020-2021 season. Injuries and SARS-CoV-2 positivity data were collected by team doctors through an online database. RESULTS: Of the 433 included players, we observed 173 SARS-CoV-2 infections and 332 indirect muscle strains. COVID-19 episodes mostly belonged to severity level I and II. The injury risk significantly increased after a COVID-19 event, by 36% (HR = 1.36, CI95% 1.05; 1.77, p-value = 0.02). The injury burden demonstrated an 86% increase (ratio = 1.86, CI95% 1.21; 2.86, p-value = 0.005) in the COVID-19 severity level II/III versus players without a previous SARS-CoV-2 infection, while level I (asymptomatic) patients showed a similar average burden (ratio = 0.92, CI95% 0.54; 1.58, p-value = 0.77). A significantly higher proportion of muscle-tendon junction injuries (40.6% vs. 27.1%, difference = 13.5%, CI95% 0.002%; 26.9%, p-value = 0.047) was found when comparing level II/III versus Non-COVID-19. CONCLUSIONS: This study confirms the correlation between SARS-CoV-2 infection and indirect muscle injuries and highlights how the severity of the infection would represent an additional risk factor.

Xi Nerve-sparing Robotic Radical Perineal Prostatectomy: European Single-center Technique and Outcomes.

Background: Radical prostatectomy (RP) represents the standard of care for the treatment of patients with organ-confined prostatic cancer. Historically, perineal RP has been described as the first surgical approach for the complete removal of the prostatic gland. In the past years, robotic techniques provided some technical advantages that allow resuming alternative approaches, such as robotic radical perineal prostatectomy (r-RPP). Objective: To present in detail the technique of Xi nerve-sparing r-RPP and to report perioperative, oncological, and functional outcomes from a European tertiary center. Design setting and participants: Patients with low- or intermediate-risk prostatic cancer not suitable for active surveillance and prostate volume up to 60 ml who underwent r-RPP between November 2018 and December 2020 were identified. Surgical procedure: All patients underwent Xi nerve-sparing r-RPP. Measurements: Baseline characteristics and intraoperative, pathological, and postoperative data were collected and analyzed. The complications were reported according to the standardized methodology to report complications proposed by European Association of Urology guidelines. Results and limitations: Overall, our series included 26 patients who underwent r-RPP. Patients' median age was 62.5 yr. Thirteen (50%) and eight (30.7%) patients showed a body mass index (BMI) of 25-30 and >30, respectively. A history of past surgical procedures was present in seven (26.8%) patients. The median prostate volume was 40 (interquartile range [IQR]: 28-52) ml. The median operative time and blood lost were 246 (IQR: 230-268) min and 275 (IQR: 200-400) ml, respectively. Overall, four (15.4%) patients reported intraoperative complications and five (19.2%) reported postoperative complications, with one (3.8%) reporting major complications (Clavien-Dindo ≥3). No patient with biochemical recurrence (BCR) was reported at 1 yr of follow-up. Continence rates were 73.0%, 84.6%, and 92.3%, respectively, at 3, 6, and 12 mo after surgery. Erectile potency recovery rates were 57.1%, 66.6%, and 80.9% at 3, 6, and 12 mo of follow-up, respectively. Conclusions: Xi r-RPP is a challenging but safe minimally invasive approach for selected patients. No patient reported BCR at 12 mo. The choice of the surgical approach for RP is likely to be based on the patient's characteristics as well as the surgeon's preferences. Patient summary: Our study suggests that Xi radical perineal prostatectomy is a safe minimally invasive approach for patients with low- or intermediate-risk prostatic cancer, and complex abdominal surgical history or comorbidities.

Transperineal interstitial laser ablation of the prostate, a novel option for minimally invasive treatment of benign prostatic obstruction.

BACKGROUND: In the algorithm of treatment of benign prostatic obstruction (BPO), the shift from medical therapy to surgery is steep in terms of invasiveness. Recently, a lively interest has developed on alternative micro-invasive options. Transperineal interstitial laser ablation (TPLA) was recently proposed for BPO treatment. OBJECTIVE: This work aims to illustrate feasibility, efficacy and safety profile of TPLA in BPO treatment. DESIGN, SETTING, AND PARTICIPANTS: We prospectively analyzed the results of TPLA performed between September 2018 and March 2019 for LUTS due to BPO, in men with prostate volume <100 ml. SURGICAL PROCEDURE: TPLA was performed in OR, under local anesthesia, using Soracte Lite-EchoLaserX4. Diode laser light is conveyed through 300 µm optical fibers introduced transperineally by 21 Ga needles and placed at a security distance from urethra and bladder neck. EchoLaser Smart Interface eases needle positioning and increases the safety. MEASUREMENTS: The primary endpoint was the variation of Qmax and IPSS at 1, 3 and 6 months. We also assessed the ejaculatory function and recorded complications. These outcomes were further investigated at 12 months by phone call. RESULTS AND LIMITATIONS: 21 men with prostate volume of 43.5 ± 8.5 ml underwent TPLA. All were discharged after 24 h, keeping the transurethral catheter for 8.7 ± 2.5d. At one month all patients but one discontinued medical therapy, showing significant advantage in Qmax (+3.4 ± 5.7 ml/s; p < 0.01) and IPSS (-5.6 ± 7.0; p < 0.01). Functional results were still progressing at 6 months, with Qmax (+4.7 ± 6.0 ml/s; p < 0.01) and IPSS improvement (-13.1 ± 4.7; p < 0.01). The ejaculatory function was preserved as the MSHQ-EjD increased (p < 0.05). The only complication was a prostatic abscess, treated with transperineal drainage and antibiotic. CONCLUSIONS: TPLA is a micro-invasive treatment for BPO showing good functional and safety outcomes. PATIENT SUMMARY: This work illustrates the results of TPLA to treat LUTS due to BPO, showing high efficacy, preservation of the ejaculation, and low complication rate.

Oncological and functional outcomes of extraperitoneal laparoscopic radical prostatectomy: An 18-years, single-center experience.

OBJECTIVE: To present a retrospective analysis on the oncological and functional outcomes of a single-center experience on a large series of extraperitoneal laparoscopic radical prostatectomies (eLRP) with an extended follow-up. MATERIALS AND METHODS: Herein we present a retrospective review of patients who underwent eLRP. Oncological and functional follow-up data were collected by means of outpatient visits and telephone interviews, assessing overall mortality and biochemical recurrence-free survival. Patients with clinical T4 stage prostate cancer (PCa), previous surgery for benign prostatic hyperplasia (BPH), previous androgen deprivation, radiotherapy, concomitant chemotherapy and/or experimental therapies, and with insufficient follow-up data were excluded. Preoperative data recorded were age, body mass index, ultrasound prostate volume, preoperative PSA and clinical stage of PCa. Operative data (operative time, nerve sparing technique and any perioperative complication) and pathological findings were obtained by consulting the surgical and pathological reports. Oncological and functional follow-up were collected during follow-up visits and telephone interview. RESULTS: Between January 2001 and December 2019, overall 938 eLRP were performed at our Institution. The median follow-up was 132 months. 69.7% of the patients had complete dataset. The estimated overall biochemical recurrence (BCR)-free survival was 71.4% at 5 years and 58.9% at 10 years. Cancer specific survival was 84,5%. Erectile function was preserved in the most of patients as postoperative IIEF-5 score within 12 months after surgery was > 12 in the 82.1%. About the urinary incontinence, 0.76% of the patients presented severe incontinence (continued and persistent loss of urine) and 7.0% were mildly incontinent (using up to one pad per day). Conclusions; eLRP has shown oncological and functional results comparable to other minimally invasive techniques and to open radical prostatectomy (ORP), with favorable perioperative outcomes than the open technique and a reduced complication rate.

Evaluation of plantar fasciopathy shear wave elastography: a comparison between patients and healthy subjects.

PURPOSE: The aim of this study is to compare elasticity features between patients with plantar fasciitis (PFis) and an asymptomatic healthy control group using shear wave elastography (SWE) and to correlate SWE values with clinical scores. METHODS: Consecutive patients diagnosed with PFis and asymptomatic subjects were enrolled in the present study. Both groups underwent clinical, ultrasound (US), and SWE evaluation. A plantar fascia thickness > 4 mm was considered pathognomonic of PFis. SWE stiffness elasticity (Young's modulus in kPa and shear wave velocity in m/s) was measured 1 cm distally from the calcaneal insertion. Correlations with VAS and the 17-Italian Foot Function Index (17-FFI) were determined. RESULTS: A total of 19 patients satisfied the inclusion criteria for the patient group and were enrolled in the study, and 21 healthy subjects were used as a control group. Statistically significant differences were found for shear wave velocity between the patient and the control group, with SWE findings of 3.8 (5.1; 1.5) m/s and 4.7 (4.07; 7.04) m/s, respectively (p = 0.006). Strong positive correlations were found between the SWE findings and both the pain and the functional scale (VAS: p = 0.001; FFI: p = 0.012). CONCLUSION: SWE allows quantitative assessment of the stiffness of the plantar fascia and can show PFis alterations, increasing the diagnostic performance of B-mode US. In addition, SWE shows a strong correlation with clinical scores, improving patient assessment and follow-up.

Elastosonographic evaluation after extracorporeal shockwave treatment in plantar fasciopathy.

AIM: To assess the ultrasound features in patients with plantar fasciopathy before and after extracorporeal shock waves therapy (ESWT), using conventional grey-scale imaging and both strain (SE) and shear wave (SWE) elastosonographic evaluation. MATERIAL AND METHOD: Consecutive patients of both sexes attending our outpatient's clinic, with diagnosis of unilateral plantar fasciopathy, were enrolled. Patients were treated with 3 sessions of ESWT once a week, and underwent clinical and ultrasound evaluation at baseline and at one and three months after treatment. Roles and Maudsley score (RM), visual analog scale (VAS) and 17-Italian Foot Function Index (FFI), were used to assess pain and functional improvement. RESULTS: Twenty patients (11 female and 9 male) were enrolled in the study. Contralateral asymptomatic healthy plantar fascia was used as a control. At baseline, SWE velocity (SWEv) showed statistically significant difference between affected 3.8 (1.5; 5.1) m/s and healthy side 4.7 (4.07; 7.04) m/s, (p=0.006); no significant difference was found for strain ratio values (p=0.656). SWEv post hoc test results showed a significant difference from baseline 3.8 (1.5-5.1) m/s and three month 5.23 (4.55-6.74) m/s follow up visit (p=0.003). Significant statistical negative correlation was found between the SWEv and VAS (p=0.001) and positive correlation between the SWEv and FFI (p=0.012). CONCLUSION: SWE was effective in assessing plantar fascia elasticity and its alteration in fasciopathy. Furthermore, on the basis of the correlation with pain and functional scales, this technique appears to be a useful additional technique to conventional ultrasound for monitoring the efficacy of treatment.

Diagnostic Accuracy of Hexaminolevulinate in a Cohort of Patients Undergoing Radical Cystectomy.

PURPOSE: To compare the accuracy of white light cystoscopy (WLC) and blue light cystoscopy (BLC) in a cohort of patients undergoing radical cystectomy (RC) for previously resected urothelial bladder cancer. PATIENTS AND METHODS: A cohort of patients undergoing RC received WLC and BLC prior radical surgery. To evaluate the residual tumor rate, the bladder was inspected after its removal and normal appearing mucosa sampled for histologic analysis. Lesions detected under WLC, BLC, or both, and biopsy samples from normal appearing mucosa, were all recorded separately. RESULTS: Starting 2011, 64 patients underwent WLC and BLC prior cystectomy. Overall, 540 tissue samples were collected during cystoscopy and from normal appearing mucosa. Residual disease was found in 31/64 (48.4%) patients, including 27 (42.1%) cases of carcinoma in situ (CIS). The accuracy of BLC was much higher than WLC, both in the diagnosis of any residual disease (87.1% vs 32.3%, and 87.9% vs 51.5%, for sensitivity and specificity, respectively), as of CIS only (92.6% vs 29.6% and 83.8% vs 51.4%). We further evaluated the diagnostic accuracy as a result of the analysis on all specimens collected during the study. A total of 535 specimens were analyzed, and 58 specimens with residual disease were found, including 48 CIS foci. Again, detection rates and measures of accuracy were much better for BLC vs WLC, both overall (86.2% vs 31%, and 98.3% vs 93.3%, for sensitivity and specificity, respectively), and when CIS only was considered (89.6% vs 31.2% and 96.9% vs 92.8%). CONCLUSIONS: Although BLC missed 12.9% of positive patients, and 7.4% of those with CIS, the agreement between BLC diagnostic accuracy and the definitive pathology was very robust.
