Natural history of histologically benign PIRADS 4-5 lesions in multiparametric MRI: Real-life experience in an academic center.

INTRODUCTION: The follow-up findings of patients who underwent prostate biopsy for prostate image reporting and data system (PIRADS) 4 or 5 multiparametric magnetic resonance imaging (mpMRI) findings and had benign histology were retrospectively reviewed. METHODS: There were 190 biopsy-naive patients. Patients with at least 12 months of follow-up between 2012 and 2023 were evaluated. All MRIs were interpreted by two very experienced uroradiologists. Of the patients, 125 had either cognitive or software fusion MR-targeted biopsies with 4 + 8/10 cores. The remaining 65 patients had in-bore biopsies with 4-5 cores. Prostate-specific antigen (PSA) levels below 4 ng/mL were defined as PSA regression following biopsy. PIRADS 1-3 lesions on new MRI images were classified as MRI regression. RESULTS: Median patient age and PSA were 62 (39-82) years and six (0.4-33) ng/mL, respectively, at the initial work-up. During a median follow-up period of 44 months, 37 (19.4%) patients were lost to follow-up. Of the remaining 153 patients, 82 (53.6%) had persistently high PSA. Among them, 72 (87.8%) had repeat mpMRI within 6-24 months which showed regressive findings (PIRADS 1-3) in 53 patients (73.6%) and PIRADS 4-5 index lesion persistence in 19 cases (26.4%). The latter group was recommended to have rebiopsy. Of these 19 patients, 16 underwent MRI-targeted rebiopsy. Prostate cancer was diagnosed in six (37.5%) patients and of these four (25%) were clinically significant (>Grade Group 1). Totally, clinically significant prostate cancer was detected in 4/153 (2.6%) patients followed up. CONCLUSION: Patients should be warned against the relative relaxing effect of a negative biopsy after identification of PIRADS 4-5 index lesion. While PSA decrease was observed in many patients during follow-up, persistent MRI findings were present in nearly a quarter of patients with persistently high PSA. A rebiopsy is warranted in these patients, with significant prostate cancer diagnosed in a quarter of patients with rebiopsy.

The effect of ultrasound-guided rectus sheath block on postoperative analgesia in robot assisted prostatectomy: A randomized controlled trial.

BACKGROUND: Postoperative pain continues to represent an important problem even after minimally invasive robotic-assisted laparoscopic radical prostatectomy, which results in discomfort in the postoperative period and sometimes prolongs hospital stays. Regional anesthesia and analgesia techniques are used in addition to systemic analgesics with the multimodal approach in postoperative pain management. Ultrasound-guided fascial plane blocks are becoming increasingly important, especially in minimally invasive surgeries. Another important cause of discomfort is urinary catheter pain. The present randomized controlled study investigated the effect of rectus sheath block on postoperative pain and catheter-related bladder discomfort in robotic prostatectomy operations. METHODS: This randomized controlled trial was conducted from March to August 2022. Written informed consent was obtained from all participants. Approval for the study was granted by the Clinical Research Ethics Committee. All individuals provided written informed consent, and adults with American Society of Anesthesiologists Physical Condition classification I to III planned for robotic prostatectomy operations under general anesthesia were enrolled. Following computer-assisted randomization, patients were divided into 2 groups, and general anesthesia was induced in all cases. Rectus sheath block was performed under general anesthesia and at the end of the surgery. No fascial plane block was applied to the patients in the non-rectus sheath block (RSB) group.Postoperative pain and urinary catheter pain were assessed using a numerical rating scale. Fentanyl was planned as rescue analgesia in the recovery room. In case of numerical rating scale scores of 4 or more, patients were given 50 µg fentanyl IV, repeated if necessary. The total fentanyl dose administered was recorded in the recovery room. IV morphine patient-controlled analgesia was planned for all patients. All patients' pain (postoperative pain at surgical site and urethral catheter discomfort) scores and total morphine consumption in the recovery unit and during follow-ups on the ward (3, 6, 12, and 24 hours) in the postoperative period were recorded. RESULTS: Sixty-one patients were evaluated. Total tramadol consumption during follow-up on the ward was significantly higher in the non-RSB group. Fentanyl consumption in the postanesthesia care unit was significantly higher in the non-RSB group. Total morphine consumption was significantly lower in the RSB group at 0 to 12 hours and 12 to 24 hours. Total opioid consumption was 8.81 mg in the RSB group and 19.87 mg in the non-RSB group. A statistically significant decrease in urethral catheter pain was noted in the RSB group at all time points. CONCLUSION: RSB exhibits effective analgesia by significantly reducing postoperative opioid consumption in robotic prostatectomy operations.

Machine learning prediction of Gleason grade group upgrade between in-bore biopsy and radical prostatectomy pathology.

This study aimed to enhance the accuracy of Gleason grade group (GG) upgrade prediction in prostate cancer (PCa) patients who underwent MRI-guided in-bore biopsy (MRGB) and radical prostatectomy (RP) through a combined analysis of prebiopsy and MRGB clinical data. A retrospective analysis of 95 patients with prostate cancer diagnosed by MRGB was conducted where all patients had undergone RP. Among the patients, 64.2% had consistent GG results between in-bore biopsies and RP, whereas 28.4% had upgraded and 7.4% had downgraded results. GG1 biopsy results, lower biopsy core count, and fewer positive cores were correlated with upgrades in the entire patient group. In patients with GG > 1 , larger tumor sizes and fewer biopsy cores were associated with upgrades. By integrating MRGB data with prebiopsy clinical data, machine learning (ML) models achieved 85.6% accuracy in predicting upgrades, surpassing the 64.2% baseline from MRGB alone. ML analysis also highlighted the value of the minimum apparent diffusion coefficient ( ADC min ) for GG > 1 patients. Incorporation of MRGB results with tumor size, ADC min value, number of biopsy cores, positive core count, and Gleason grade can be useful to predict GG upgrade at final pathology and guide patient selection for active surveillance.

Rational use of Ga-68 PSMA PET-CT according to nomograms and risk groups for the detection of lymph node metastasis in prostate cancer.

OBJECTIVES: The aim was to ensure efficient utilization of PSMA PET-CT by examining the correlation of pathological lymph node metastasis with nomogram scores and risk classifications. METHODS AND MATERIALS: Robot-assisted radical prostatectomy and bilateral pelvic lymph node dissections for pelvic lymph nodes were performed using the same template. Bilaterally pelvic lymph nodes were removed within the boundaries of genitofemoral nerves, psoas muscle and lateral pelvic wall laterally, ureteric crossing of the iliac vessels superiorly, lateral bladder wall medially, Cooper ligaments distally, and endopelvic fascia, neurovascular bundles and internal iliac arteries posteriorly. Clinical nomograms were used to calculate the probability of lymph node metastasis preoperatively. Using receiver operating characteristics analysis, discriminatory cut-offs were calculated. The diagnostic performance of PSMA PET-CT was determined for detecting lymph node metastasis. RESULTS: For 81 patients, the median age was 64 years. The median PSA was 6.8 ng/ml. Most patients were in the D'Amico intermediate (56.8%) and high (37%) risk groups. Median Briganti 2017, MSKCC, and Partin scores were 35 (4-99), 37 (8-90), and 12 (2-38), respectively, in pN1 patients. The area under the curve for Briganti 2017, MSKCC, Partin nomograms and PSMA PET-CT scans were 0.852, 0.871, 0.862, and 0.588. Sensitivity, specificity, positive predictive value and negative predictive value for Ga-68 PSMA PET-CT for lymph node metastasis detection were 21.4%, 94%, 42.9%, and 85.1%, respectively, for the whole group. By using higher threshold values for clinical nomograms (Briganti 2017 >32, MSKCC >12, Partin >5), PSMA PET-CT had higher sensitivity (42.9, 30, 27.2) in detecting lymph node metastasis. CONCLUSIONS: Patients in the D'Amico high-risk group and those with high nomogram scores are the best candidates who will benefit from preoperative PSMA PET-CT staging to estimate lymph node metastasis.

Intraoperative Frozen Section via Neurosafe During Robotic Radical Prostatectomy in the Era of Preoperative Risk Stratifications and Primary Staging With mpMRI and PSMA-PET CT: Is There a Perfect Candidate?

BACKGROUND: We aimed to analyze the effect of preoperative risk assessment including Ga-68 PSMA PET and multiparametric magnetic resonance imaging (mpMRI) on nerve sparing practices, positive surgical margin (PSM) rates and oncological outcomes based on a comparison between patients underwent RARP with and without Neurosafe (NS). METHODS: Patients underwent RARP with NS (RARP-NS) or without (RARP-only) NS retrospectively evaluated. Suspicion for extracapsular extension on mpMRI and/or Ga-68 PSMA PET was recorded as i(imaging)T3. NS was performed according to the Martini-Klinik technique. PSM at preserved bundle side were called PSM at region of interest (ROI) while the others were elsewhere. RESULTS: A total of 208 patients (90 in RARP-NS, 118 in RARP-only groups) were included. Preoperatively the RARP-only group showed significantly higher mean PSA (p = .01) and PIRADS 5 (p = .002) findings and had more D'Amico high risk (DAHR) patients (p = .08). The overall PSM rates for pT2 versus pT3 disease were 7.5% versus 21.6 and 15.6% versus 55% in RARP-NS and RARP-only groups, respectively. NS resulted in more bilaterally preserved bundles (81.1% vs. 66.3%) and less PSM at the ROI (3.3% vs. 23.4%) than RARP-only group. NS outperformed RARP-only in all clinical settings had its highest differential benefit in more bilateral nerve sparing and less PSM at ROI in patients with both DAHR and iT3 disease. BCR rates were 2.2% and 2.5% for RARP-NS and RARP only groups, respectively (p = .4). One patient in RARP-NS and 9 in RARP-only groups had PSA persistence (p = .02). CONCLUSION: RARP-NS led to more preserved bundles with less PSM. It was especially useful in DAHR patients with preoperative extracapsular extension suspicion in imaging simultaneously.

Investigation of hearing aid users' speech understanding in noise and their spectral-temporal resolution skills.

Purpose: Our study aims to compare speech understanding in noise and spectral- temporal resolution skills with regard to the degree of hearing loss, age, hearing aid use experience and gender of hearing aid users. Methods: Our study included sixty-eight hearing aid users aged between 40-70 years, with bilateral mild and moderate symmetrical sensorineural hearing loss. Random gap detection test, Turkish matrix test and spectral-temporally modulated ripple test were implemented on the participants with bilateral hearing aids. The test results acquired were compared statistically according to different variables and the correlations were examined. Results: No statistically significant differences were observed for speech-in-noise recognition, spectral-temporal resolution among older and younger adults in hearing aid users (p>0.05). There wasn't found a statistically significant difference among test outcomes as regards different hearing loss degrees (p>0.05). Higher performances were obtained in terms of temporal resolution in male participants and participants with more hearing aid use experience (p<0.05). Significant correlations were obtained between the results of speech-in-noise recognition, temporal resolution and spectral resolution tests performed with hearing aids (p<0.05). Conclusion: Our study findings emphasized the importance of regular hearing aid use and it showed that some auditory skills can be improved with hearing aids. Observation of correlations among the speech-in-noise recognition, temporal resolution and spectral resolution tests have revealed that these skills should be evaluated as a whole to maximize the patient's communication abilities.

Preoperative Magnetic Resonance Imaging Cannot Predict the Presence of a Rare Myoid Gonadal Stromal Testicular Tumor: A Case Report.

Testicular myoid gonadal stromal tumors (MGSTs) are rare neoplasms. While past research has detailed the pathological characteristics of these tumors, the radiological differences between MGST and other types of testicular tumors have not been elucidated. Our study aimed to reveal the possible distinctive features of MGST using magnetic resonance imaging (MRI). We report a 24-year-old patient presenting with a left scrotal mass. During the patient's preoperative MRI, we observed a testicular tumor measuring 2.5 cm that was consistent with the findings of a seminoma. The serum tumor markers were within the normal range. The T1-weighted MRI revealed a solid mass that was isointense-slightly hyperintense compared to the testicular parenchyma, while the mass appeared homogeneously hypointense on the T2-weighted imaging. The patient was planned to undergo left inguinal orchiectomy with the final pathological diagnosis of MGST. The MGST cannot be distinguished from other testicular tumors with certainty based on any MRI findings. The main tool for diagnosis should be based on the histomorphological characteristics and the immunohistochemical profile of the mass.

Postchemotherapy robotic retroperitoneal lymph node dissection for non-seminomatous germ cell tumors in the lateral decubitus position: oncological and functional outcomes.

PURPOSE: Retroperitoneal lymph node dissection (RPLND) is recommended for residual masses following chemotherapy for non-seminomatous germ cell tumors (NSGCT). Recently, aberrant recurrence patterns were reported in patients who underwent robotic RPLND. We aimed to evaluate perioperative safety in addition to functional and early oncological outcomes of postchemotherapy robotic RPLND (pcR-RPLND) for NSGCT. METHODS: A total of 25 patients with NSGCT who underwent a pcR-RPLND between January 2011 and June 2022 were evaluated retrospectively. Descriptive statistics were provided for demographics, clinical characteristics, intraoperative and postoperative parameters. Functional and oncological outcomes were recorded. RESULTS: The median patient age was 28.9 years (IQR 21.5-32.4). The median retroperitoneal tumor size was 2.6 cm (IQR 1.5-3.5). Intraoperative complications occurred in only one case and the open conversion rate was 12%. There were seven cases with postoperative complications (Clavien grade II: 5 and IIIa: 2). Patients were followed for a median of 33.2 months (IQR 14.8-43.0). Antegrade ejaculation was preserved in 85.7% of the patients. Two patients (8%) relapsed and both had out-of-field recurrences at unusual sites (perinephric fat and omentum). Of those, one patient died (4%) of testicular cancer. CONCLUSION: pcR-RPLND is a feasible and technically reproducible procedure with favorable perioperative morbidity, low rate of complications, and acceptable postoperative ejaculatory function. Although the recurrence rate was low (8%), recurrences were observed at unusual sites. Further studies are required to investigate any association between the robotic approach and aberrant recurrence patterns.

The role of the size and number of index lesion in the diagnosis of clinically significant prostate cancer in patients with PI-RADS 4 lesions who underwent in-bore MRI-guided prostate biopsy.

PURPOSE: To evaluate the contribution of the size and number of the sampled lesions to the diagnosis of clinically significant prostate cancer (CSPC) in patients who had PI-RADS 4 lesions. METHODS: In this retrospective study, a total of 159 patients who had PI-RADS 4 lesions and underwent In-bore MRI-Guided prostate biopsy were included. Patients with a lesion classified as Grade Group 2 and above were considered to have CSPC. Univariate and multivariate regression analyses were used to evaluate the factors affecting the diagnosis of prostate cancer (PCa) and CSPC. RESULTS: A great majority (86.8%) of the patients were biopsy-naïve. About three-fourths (71.7%) had PCa, and half (54.1%) had CSPC. When the patients were divided into three groups according to the index lesion size (< 5 mm, 5-10 mm, and > 10 mm), the prevalence of PCa was 64.3, 67.5, and 82.4% and the prevalence of CSPC was 42.9, 51.2, and 64.7%, respectively. In multivariate analysis, age, index lesion size, prostate volume (< 50 ml) and being biopsy-naïve were found significant for PCa, while age and prostate volume (< 50 ml) were significant for CSPC. CONCLUSION: The number of lesions was found to be insignificant in predicting PCa and CSPC. While the size of PI-RADS 4 lesions was significant in predicting PCa, it had no significance in detecting CSPC.

Tinnitus in patients recovering after COVID-19: observational and cross-sectional study.

PURPOSE: In our study, it was aimed to determine the tinnitus rate in patients who recovered from COVID-19. METHODS: The study included 279 individuals aged 18-60 years, who recovered from COVID-19 within the last month and did not have a chronic disease. Visual Analogue Scale and Tinnitus Handicap Inventory were used for assessment in participants with tinnitus. RESULTS: While 201 participants (72.00%) included in the study stated that they did not have tinnitus, 78 participants (28.00%) reported that they had tinnitus. Twenty-eight (10%) of the participants stated that they had no tinnitus before COVID-19 and that tinnitus started with COVID treatment; 16 (5.70%) of the participants stated that tinnitus was not present before COVID-19 and started after recovery. The mean tinnitus severity was 4.50 ± 2.16; tinnitus frequency/duration was 4.19 ± 2.45; tinnitus discomfort was 4.41 ± 2.50, and the total scores of the tinnitus handicap inventory were 49.56 ± 9.81. There was statistically borderline significance between tinnitus frequency/duration scores according to age groups (p = 0.052). Statistically significant differences were found for tinnitus severity (p = 0.033) and discomfort scores (p = 0.014) according to age groups. In addition, a statistically significant difference was observed between the tinnitus severity scores of the participants with and without a history of hospitalization (p = 0.035). CONCLUSION: Clinicians should keep in mind that tinnitus can be caused by COVID-19 as well as pre-existing tinnitus can be exacerbated by it but most participants in our study did not have post-COVID-19 tinnitus.

Pathological Accuracy in Prostate Cancer: Single-Center Outcomes of 3 Different Magnetic Resonance Imaging-Targeted Biopsy Techniques and Random Systematic Biopsy.

OBJECTIVE: The aim of this study is to compare systematic, cognitive fusion, in-bore, and software fusion prostate biopsies regarding rates of and risk factors for pathological upgrading. MATERIAL AND METHODS: Charts of 291 patients with systematic biopsy (n = 105), magnetic resonance imaging- targeted cognitive fusion (n = 58), in-bore (n = 68), and software fusion biopsy (n = 60), and who subsequently underwent radical prostatectomy were retrospectively evaluated. The degree of similarity between the grade groups reported in the biopsy and radical prostatectomy pathology results was recorded. Analyses of the associated factors for concordance and discordance were performed with univariate and multivariate methods. RESULTS: The concordance rates were as follows: systematic biopsy = 42.8%, cognitive fusion-targeted biopsy = 50%, in-bore fusion-targeted biopsy = 61.8, and software fusion biopsy = 58.4%. The upgrade rate of systematic biopsy (46.6%) was higher than cognitive fusion-targeted biopsy (27.6%), in-bore fusiontargeted biopsy (26.4%), and software fusion-targeted biopsy (18.3%). The number of positive cores was significantly associated with grade group concordance for the systematic biopsy group (P = .040). Within the cognitive fusion-targeted biopsy cohort, number of positive cores was the only parameter that exhibited a significant association with grade group concordance in multivariate analysis (P = .044). Considering the in-bore fusion-targeted biopsy group, maximum tumor length was statistically significant (P = .021). In the software fusion-targeted biopsy group, low prostate volume was found to be the only significant predictor for grade group accordance (P = .021). CONCLUSION: Magnetic resonance imaging-targeted biopsy techniques showed higher concordance and lower upgrade rates compared to systematic biopsy. For systematic biopsy and cognitive fusion-targeted biopsy, the number of positive cores was associated with grade group concordance, while maximum tumor length in in-bore fusion-targeted biopsy and low prostate volume for in-bore fusion-targeted biopsy were associated with grade group concordance. Among the MRI-targeted biopsy methods, in-bore fusion-targeted biopsy and software fusion-targeted biopsy were more accurate than cognitive fusion-targeted biopsy in terms of grade group.

Endopelvic Fascia Sparing Robotic Radical Cystectomy with Intracorporeal Studer Pouch with Balbay's Technique.

Background and Objectives: Robotic radical cystectomy (RARC) with intracorporeal urinary diversion is a technically complicated, time-consuming procedure. The aim of this study was to present the operative, pathological, oncological, and functional outcomes of patients who underwent endopelvic fascia sparing (EPFS) RARC with intracorporeal Studer pouch formation. To the best of our knowledge, this is first series in the literature that includes EPFS RARC. Methods: Between October 1, 2019 and April 30, 2022, 10 bladder cancer patients underwent EPFS RARC, bilateral extended pelvic lymph node dissection with intracorporeal Studer pouch reconstruction with Balbay's technique. Patient demographics, operative, and post-operative parameters were recorded. Results: Among 10 patients, 8 were male and 2 were female. Mean operative time, median estimated blood loss, and median duration of hospital stay was 530 minutes, 316 ml, and 8 days, respectively. One month postoperatively, the mean maximum flow, average flow rate, mean voided, and post-voided urine volume were 20.2 ml/sec, 4.4 ml/sec, 273.6 ml, and 3.5 ml, respectively. All of the patients were fully continent during day-time, three had mild night-time incontinence requiring pad use (both patients 1 pad per night). During a mean 11.5 months of follow up, zero patients died. One patient with a pathological, stage 4 tumor, had nodal recurrence at six months postoperatively. No distant metastasis were detected. Conclusion: Endopelvic fascia sparing RARC has very promising early functional results with safe oncological outcomes and low complication rates.

The Effect of Multichannel and Channel-Free Hearing Aids on Spectral-Temporal Resolution and Speech Understanding in Noise.

BACKGROUND: Identifying and understanding speech is difficult for individuals with sensorineural hearing loss, especially in noisy environments. Possible causes include less audibility of the signal, impaired temporal resolution, and low selectivity of frequency. The hearing aid is the most common option used to minimize the problems faced by individuals with sensorineural hearing loss. PURPOSE: This article investigates the effects of multichannel and channel-free hearing aid signal processing techniques on spectral-temporal resolution and speech understanding in noise. RESEARCH DESIGN: An experimental study was used in which the determined tests were applied to the participants. STUDY SAMPLE: Thirty-four individuals with bilateral symmetrical sensorineural hearing loss between the ages of 18 and 70 were included in our study. DATA COLLECTION AND ANALYSIS: Spectral-temporally modulated ripple test, random gap detection test (RGDT), and Turkish matrix test were applied to the participants using multichannel and channel-free hearing aids. All the data obtained were compared statistically in terms of the performances of the hearing aids. RESULTS: There was no significant difference between multichannel and channel-free hearing aids for spectral resolution and speech understanding in noise tests (p > 0.05). While there was no significant difference between the two hearing aids for 500 and 4,000 Hz RGDT in temporal resolution measurement (p > 0.05), for 1,000 Hz (p = 0.045), 2,000 Hz (p = 0.046), and composite RGDT (p = 0.001), statistically significant better performances were obtained with the channel-free hearing aids. CONCLUSION: It is thought that faster processing of the incoming signal in the channel-free hearing aids improves the temporal resolution performance. It is predicted that our study findings might help to determine the signal processing technique that will maximize the communication skills of the patients in various conditions.

Histologically benign PI-RADS 4 and 5 lesions contain cancer-associated epigenetic alterations.

BACKGROUND: The detection rate of clinically significant prostate cancer has improved with the use of multiparametric magnetic resonance imaging (mpMRI). Yet, even with MRI-guided biopsy 15%-35% of high-risk lesions (Prostate Imaging-Reporting and Data System [PI-RADS] 4 and 5) are histologically benign. It is unclear if these false positives are due to diagnostic/sampling errors or pathophysiological alterations. To better understand this, we tested histologically benign PI-RAD 4 and 5 lesions for common malignant epigenetic alterations. MATERIALS AND METHODS: MRI-guided in-bore biopsy samples were collected from 45 patients with PI-RADS 4 (n = 31) or 5 (n = 14) lesions. Patients had a median clinical follow-up of 3.8 years. High-risk mpMRI patients were grouped based on their histology into biopsy positive for tumor (BPT; n = 28) or biopsy negative for tumor (BNT; n = 17). From these biopsy samples, DNA methylation of well-known tumor suppressor genes (APC, GSTP1, and RARß2) was quantified. RESULTS: Similar to previous work we observed high rates of promoter methylation at GSTP1 (92.7%), RARß2 (57.3%), and APC (37.8%) in malignant BPT samples but no methylation in benign TURP chips. Interestingly, similar to the malignant samples the BNT biopsies also had increased methylation at the promoter of GSTP1 (78.8%) and RARß2 (34.6%). However, despite these epigenetic alterations none of these BNT patients developed prostate cancer, and those who underwent repeat mpMRI (n = 8) demonstrated either radiological regression or stability. CONCLUSIONS: Histologically benign PI-RADS 4 and 5 lesions harbor prostate cancer-associated epigenetic alterations.

The Impact of Visible Tumor (PI-RADS ≥ 3) on Upgrading and Adverse Pathology at Radical Prostatectomy in Low Risk Prostate Cancer Patients: A Biopsy Core Based Analysis.

BACKGROUND: The objective of this study was to investigate the impact of the characteristics of a single visible tumor (Prostate Imaging-Reporting and Data System [PI-RADS]≥3) on upgrading and adverse pathology at radical prostatectomy (RP) in biopsy naïve low risk prostate cancer (PCa) patients. MATERIALS AND METHODS: We retrospectively reviewed 64 biopsy naïve patients from 3 different referral centers between 2018 and 2020 with a PSA<10, cT1c disease, a single PI-RADS≥ 3 index lesion in multiparametric-MRI (mp-MRI), all bearing a GG 1 tumor sampled software fusion biopsy, who underwent RP. Preoperative clinical variables including the localization, number and tumor burden of positive cores for each PI-RADS category were related to upgrading and adverse pathology (GG>2 and/or pT3 and/or lymph node positive disease) at RP. RESULTS: Overall 37 patients (57.8%) were upgraded with a significant difference of upgrading in PI-RADS3 (30.0%) versus PI-RADS 4 (67.6%) (P = .007) and PI-RADS 4-5 (70.5%) lesions (P = .002). Thirty-three of 37 GG1 tumors were upgraded to GG2, while 6 of these 33 (18.2%) had adverse pathology as well. Overall 9 patients (14.1%) had adverse pathology at RP all harboring PI-RADS4-5 lesions. The number of positive cores differed significantly between the upgraded and nonupgraded patients. Adverse pathology group had significantly higher tumor volume at RP. CONCLUSION: PI-RADS4-5 lesions are the independent predictors of upgrading and adverse pathology in low risk PCa with visible tumors. Upgrading and adverse pathology were closely related to the number of positive combined cores reflecting the role of tumor volume. This should be kept in mind in shared decision making of an individual patient with low risk disease and a visible tumor.

The effect of latin dance on dynamic balance.

BACKGROUND: Figures and movements in Latin dance are effectively used to provide posture stabilization and balance control. A Computerized Dynamic Posturography can be used to complete a functional evaluation of postural control and stability in static and dynamic conditions, mediated by the interaction between the visual, vestibular, and somatosensory systems. RESEARCH QUESTION: According to the results of Computerized Dynamic Posturography, do dancers have better postural control and stability when compared to non-dancers, and can dance activity be recommended for vestibular rehabilitation? MATERIAL AND METHODS: Our study included 26 professional Latin dancers and 26 non-dancers as a control group whoboth had no problems with their hearing or balance. Pure-tone audiometry and Computerized Dynamic Posturography tests were applied to the participants. The test results for the professional dancers and the control group were compared and evaluated. In statistical analysis, the Mann-Whitney U and Independent Samples T tests were used. A value of p < 0.05 was accepted for significance. RESULTS: According to the results of the Computerized Dynamic Posturography, the dancers generally performed better than the control group. While statistically significant and better performances were observed in dancers in terms of the composite balance, visual and vestibular scores within the scope of the Sensory Organization Test (p < 0.05), no statistically significant difference was found for somatosensory and preference scores (p > 0.05). Also, significant differences were obtained between the two groups in some subtests of Adaptation, Unilateral Stance and Limits of Stability assessment (p < 0.05). No significant difference was observed in Rhythmic Weight Shift results (p > 0.05). IMPORTANCE: The results of thisresearch demonstrate that balance and posture improve through dance. Therefore, adding appropriate dance activities to vestibular rehabilitation programmes might be helpful.

Gardnerella vaginalis: Is it an Underestimated Cause of Urinary Symptoms in Males?

Objective: This study aimed to investigate the detection rate of Gardnerella vaginalis by multiplex PCR test in the genitourinary samples of male patients with suspected urethritis and related symptoms. Materials and Methods: A total of 144 male patients who presented to our department between February 2021 and October 2021, either with urinary symptoms or concerns following unprotected sex, were included in the study.A total of 128 (88.9%) first-void urine samples, 15 (10.4%) urethral swabs, and one (0.7%) semen sample were obtained. NeoPlex STI-14 Detection Multiplex PCR Kit (GeneMatrix Inc. Seongnam, South Korea) was used to investigate any of the following pathogens: Candida albicans, Chlamydia trachomatis, G. vaginalis, Mycoplasma genitalium, Mycoplasma hominis, Neisseria gonorrhoeae, Trichomonas vaginalis, Ureaplasma parvum, Ureaplasma urealyticum,herpes simplex virus type 1 (HSV-1), herpes simplex virus type 2 (HSV-2), Treponema pallidum , Streptococcus agalactiae, and Haemophilus ducreyi. The patients with positive results for G. vaginalis were retrospectively analyzed. Results: The patients' median age was 37 (range: 21 to 71 years old). G. vaginalis was the most frequently detected microorganism (n=23; 15.9%). Other microorganisms found in order of frequency were U. urealyticum (n=19; 13.2%), U. parvum (n=15; 10.4%), C. trachomatis (n=11; 7.6%), M. genitalium (n=8; 5.6%), HSV-2 (n= 7; 4.9%), N. gonorrhoeae (n=6; 4.2), HSV-1 (n=2; 1.4%), M. hominis (n=1, 0.7%), and C. albicans (n=1, 0.7%). Fifteen patients (65%) were positive for one or two microbial agents together with G. vaginalis, while in eight patients (35%), G. vaginalis was the only isolated agent. Six of these eight patients and 14 of the remaining 15 were symptomatic. Conclusion: With the introduction of multiplex PCR tests, including those for G. vaginalis, we can expect a higher detection rate of these species of bacteria in male genitourinary samples, which could be the cause of unexplained urinary/urethral symptoms.

In-bore MRI-guided prostate biopsy in a patient group with PI-RADS 4 and 5 targets: A single center experience.

PURPOSE: To determine the diagnostic yield of magnetic resonance imaging (MRI) guided in-bore biopsy in patients with high likelihood multiparametric MRI (mpMRI) findings, regarding overall and clinically significant prostate cancer (csPCa) detection rates and concordance of biopsy and radical prostatectomy (RP) Gleason scores (GS). METHODS: This retrospective study consisted of 277 Prostate Imaging Reporting and Data System (PI-RADS) assessment category 4 and 5 targets in 246 patients (mean age, 65.7 years; median prostate specific antigen value, 7.75 ng/mL) who had undergone in-bore biopsy at our institution between 2012 and 2020. Eighty-one patients who underwent RP were eligible for the concordance analysis of biopsy and RP specimen GS. RESULTS: Overall PCa detection rates were 80.5 % per patient (198/246) and 78 % per target (216/277) and 83.5 % and 67.4 % in primary (biopsy naive) and secondary (at least one negative prior biopsy) settings. csPCa was found in 63 % overall, 66 % of patients (132/200) in the primary, and 50 % of patients (23/46) in the secondary biopsy settings (p < 0.001). The prostate cancer detection rate was 68 % and 92 % in PI-RADS 4 and 5, respectively (p < 0.001). In the radical prostatectomy subcohort, 27.2 % of patients were upgraded, 8.6 % of patients were downgraded from needle biopsy. Significant complications occurred in 1.2 % of patients. CONCLUSIONS: MRI-guided in-bore prostate biopsy has a high detection rate of csPCa in primary and secondary biopsy cohorts. Biopsy results were satisfactory in terms of the number of positive cores, cancer percentage in positive cores, and concordance of GS in needle biopsy and RP specimen.

Genitalia Preserving Robotic Radical Cystectomy with Intracorporeal Studer Pouch Formation in the Female: Experience in 5 Cases.

We present operative, postoperative, oncologic and functional outcomes of genital tract sparing robot-assisted laparoscopic radical cystectomy, bilateral extended pelvic lymph node (LN) dissection and intracorporeal Studer pouch construction on five female patients with bladder cancer. One of the cases had concomitant nephroureterectomy performed due to a non-functioning kidney. Median patient age, mean operation time, median estimated blood loss and mean duration of hospital stay were 59 (39-78), 462 ± 25, 400 (50-970), 8.8 ± 2.5, respectively. Pathologic stages were pTis (n=1), pT1 (n=1), pT3 (n=1), pT4a (n=1) and pT4b (n=1). Mean LN yield was 32.4 ± 8.9. Positive surgical margins were detected in 2 patients with pT4 diseases. Only minor complications developed that were resolved with medical treatment. Two patients had no, 1 patient had mild, and 2 patients had moderate daytime incontinence. One patient had good, 3 patients had fair, and 1 had poor night-time incontinence. This complex robotic surgery can be performed safely with acceptable short-term surgical, oncological and functional outcomes.

The clinical impact of Prostate Imaging-Reporting and Data System classification in patients with haemospermia undergoing multiparametric magnetic resonance imaging of the prostate.

In this study, we evaluated the role of the Prostate Imaging-Reporting and Data System (PI-RADS) classification of multiparametric magnetic resonance imaging (mpMRI) to determine the likelihood of prostate cancer (PCa) in patients with haemospermia. Fifty-one patients presenting with haemospermia between 2018 and 2020 were included in this retrospective study. Forty-two of the patients (82.4%) were over 40 years, and the median prostate-specific antigen (PSA) level was 1.4 ng/ml. Fourteen of the patients (27.5%) had recurrent haemospermia. All patients underwent mpMRI, and assessments were classified according to PI-RADS v2. The mpMRI revealed PI-RADS one to four lesions in 10 (19.6%), 30 (58.8%), 6 (11.8%) and 5 (9.8%) patients respectively. One patient with PI-RADS 3 and five with PI-RADS 4 lesions underwent cognitive fusion prostate biopsy depending on MRI findings, and two patients with PI-RADS 4 lesions were diagnosed with PCa. Patients with haemospermia and risk factors, that is aged over 40 years, a high PSA level or familial history of PCa, need a more thorough evaluation with mpMRI.
