Accuracy of elastic fusion biopsy: Comparing prostate cancer detection between targeted and systematic biopsy.

INTRODUCTION: When performing targeted biopsy (TBx), the need to add systematic biopsies (SBx) is often debated. Aim of the study is to evaluate the added value of SBx in addition to TBx in terms of prostate cancer (PCa) detection rates (CDR), and to test the concordance between multiparametric magnetic resonance imaging (mpMRI) findings and fusion biopsy results in terms of cancer location. METHODS: We performed a retrospective, multicentric study that gathered data on 1992 consecutive patients who underwent elastic fusion biopsy between 2011 and 2020. A standardized approach was used, with TBx (2-4 cores per target) followed by SBx (12-14 cores). We assessed CDR of TBx, of SBx, and TBx+SBx for all cancers and clinically significant PCa (csPCa), defined as ISUP score ≥2. CDR was evaluated according to radiological and clinical parameters, with a particular focus on PI-RADS 3 lesions. In a subgroup of 1254 patients we tested the discordance between mpMRI findings and fusion biopsy results in terms of cancer location. Uni- and multivariable logistic regression analyses were performed to identify predictors of CDR. RESULTS: CDR of TBx+SBx was 63.0% for all cancers and 38.8% of csPCa. Per-patient analysis showed that SBx in addition to TBx improved CDR by 4.5% for all cancers and 3.4% for csPCa. Patients with lesions scored as PI-RADS 3, 4, and 5 were diagnosed with PCa in 27.9%, 72.8%, and 92.3%, and csPCa in 10.7%, 43.6%, and 69.3%, respectively. When positive, PI-RADS 3 lesions were ISUP grade 1 in 61.1% of cases. Per-lesion analysis showed that discordance between mpMRI and biopsy was found in 56.6% of cases, with 710 patients having positive SBx outside mpMRI targets, of which 414 (58.0%) were clinically significant. PSA density ≥0.15 was a strong predictor of CDR. CONCLUSIONS: The addition of systematic mapping to TBx contributes to a minority of per-patient diagnoses but detects a high number of PCa foci outside mpMRI targets, increasing biopsy accuracy for the assessment of cancer burden within the prostate. High PSA-density significantly increases the risk of PCa, both in the whole cohort and in PI-RADS 3 cases.

[Bladder injury after TVT transobturator]. / Plaie vésicale après bandelette trans-obturatrice.

The new minimally invasive technique for surgical treatment of female stress urinary incontinence via a transobturator approach is designed to reconstitute the urethral support sling while preserving the retropubic space. One of the advantages of this technique is that it avoids the risk of bladder injuries, frequently observed during passage of TVT into the prevesical space, particularly when it has been previously operated. However, recent anatomical studies have shown that bladder injuries may still occur with the use of this new transobturator approach. The present case is the first published case reporting a bladder injury during transobturator insertion of TVT.

Are early continence recovery and oncologic outcomes influenced by use of different devices in prostatic apex dissection during laparoscopic radical prostatectomy?

BACKGROUND AND PURPOSE: Treatment of patients with prostate cancer has evolved considerably in the last decade, especially in terms of minimization of the negative impacts on erectile function and continence to ensure good quality of life for treated patients. New surgical devices, such as dissectors and hemostatic scalpels, allow precise definition of the surgical field with finer dissection of the anatomic structures, with subsequent reductions in operative times and better oncologic and functional outcomes. Although monopolar scissors (MS) are still widely used, radiofrequency (RF) and ultrasound (US) scalpels have been introduced recently in laparoscopic radical prostatectomy (LRP). Despite the widespread use of these scalpels, however, few studies have compared these devices in terms of oncologic and functional outcomes after radical prostatectomy. The present study aimed to prospectively assess the impact of MS, RF, and US scalpels on margin status at apex, and recovery of urinary continence and erectile function in patients undergoing extraperitoneal LRP. PATIENTS AND METHODS: A total of 150 men were prospectively enrolled between September 2009 and April 2013 and postoperatively evaluated for continence and clinical factors. RESULTS: There were no differences in terms of operative times (P=0.9433), blood loss (P=0.9681), apical margin positivity (P=0.3965) or postoperative hospital stay (P=0.9257) among the groups. Moreover, no differences in the functional outcome scores, as evaluated by the International Consultation on Incontinence self-administered Questionnaire, at 1, 3, and 6 months postsurgery were observed. CONCLUSION: Our study represents the first evaluation of continence recovery in LRP with respect to different devices used for prostatic apex dissection. We found that the oncologic, functional, and operative outcomes were similar between these different devices during LRP, with no scalpel demonstrating superiority in continence recovery.

Pain and morbidity of an extensive prostate 10-biopsy protocol: a prospective study in 289 patients.

PURPOSE: Some studies imply that increasing the number of prostate biopsy cores may improve the cancer detection rate. We performed a prospective study to evaluate pain and morbidity after an extensive transrectal ultrasound guided 10-core biopsy protocol. MATERIALS AND METHODS: A total of 289 consecutive men with abnormal digital rectal examination findings and/or increased prostate specific antigen underwent extensive prostate biopsy involving 6 sextant and 4 peripheral biopsies. Each received an information leaflet a few days before the procedure. A single dose of fluoroquinolone and a rectal enema were administered before biopsy. In no case was the procedure performed using anesthesia. Immediately after biopsy patients were asked to complete a self-administered nonvalidated questionnaire evaluating the degree of pain and/or discomfort using a visual analog scale. In another questionnaire they listed the side effects noticed during month 1 after biopsy. RESULTS: Although 48% of the 275 men who completed the initial questionnaire reported anxiety before the procedure, 78.8% of them were completely reassured by the information brochure. Of the 275 patients 47.6% described the procedure as painful, including only slightly painful (analog visual scale 3 or less) in 67.9%, while 33.8% described it as uncomfortable but not painful and 18.6% thought that it was neither painful nor uncomfortable. Of the 115 patients who engaged in sexual intercourse during month 1 after the procedure 78.3% noticed hematospermia an average of 10.9 days in duration. Of the 164 men who completed questionnaire 2, 74.4% noticed hematuria an average of 2.7 days in duration, 3.7% noticed pyrexia and 1.2% noticed acute prostatitis. In the 59 patients (36%) who reported delayed perineal pain it was slight in 64.4%, moderate in 30.5% and severe in 5.1%. No patient required hospitalization. CONCLUSIONS: Although minor complications are common, the extensive 10-core prostate biopsy protocol is associated with few major complications. The occurrence and intensity of pain and discomfort are in the range reported after the standard 6-core biopsy protocol.
