Background: Patients hospitalized due to gross hematuria frequently complete evaluation in the outpatient setting. The use of office flexible cystoscopy during hospitalization may lead to prompt diagnosis and treatment but can be limited due to low visualization and artifacts that can hamper diagnostic ability. Objective: The objective of this study was to assess flexible cystoscopy findings and yield performed in patients hospitalized due to gross hematuria. Methods: Medical records of patients who underwent flexible cystoscopy while hospitalized during September 2018–December 2019 were reviewed. Cystoscopic findings were categorized into (1) suspicious mass in the bladder or prostate, (2) nonsuspicious changes in the bladder, and (3) nondiagnostic exam. Descriptive statistics were used to report the clinical characteristics of the study cohort and the findings of cystoscopy. Univariate logistic regression analyses were used to identify predictors of malignant findings. Results: The study cohort consisted of 69 patients (median age of 76 years). Initial cystoscopy findings were suspicious for malignancy in 26/69 patients (38%), nonsuspicious for malignancy in 34/69 patients (49%), and nondiagnostic in 9/69 patients (13%). The median follow-up time was 9 months (range 4–14 months). Twenty patients (29%) were diagnosed with malignancy (sensitivity of 75% and specificity of 78%). The procedure led to either diagnosis or treatment of 39 patients (57%). However, in 30 patients (43%), the initial cystoscopy did not aid in the diagnosis, led to misdiagnoses, or required a follow-up cystoscopy. On univariate analyses, none of the precystoscopy variables were predictive of bladder malignancy. Conclusion: Flexible cystoscopy in the setting of acute hematuria requiring hospitalization did not lead to diagnosis or treatment in over 40% of cases. In this setting, consideration should be given to performing an upfront cystoscopy under anesthesia. [ABSTRACT FROM AUTHOR]

Objective: To investigate the prevalence of testicular microlithiasis and its association with sperm retrieval rates and histopathology in men with non‐obstructive azoospermia. Methods: A total of 120 men underwent scrotal ultrasonography prior to microsurgical testicular sperm extraction. Sperm retrieval rate, testicular histopathology, testicular size, reproductive hormones, karyotyping, Y chromosome microdeletion analyses, and presence of varicoceles and hydroceles were compared between men with and without testicular microlithiasis. Results: The total sperm retrieval rate was 40%. Ten men with normal spermatogenesis were excluded. The remaining 110 men with non‐obstructive azoospermia were analyzed and testicular microlithiasis was detected in 16 of them (14.5%). The sperm retrieval rate in that subgroup was only 6.2% (1/16) as opposed to 39.4% (37/94) in men with non‐obstructive azoospermia and no evidence of microlithiasis (P = 0.009). The mean right and left testicular diameters were significantly lower in the microlithiasis group (P = 0.04). On multivariate logistic regression analysis, the presence of mictolithiasis (odds ratio 7.4, 95% confidence interval 2.3, 12.2; P = 0.01) was the only independent predictor of unsuccessful sperm retrieval. The 15 patients with microlithiasis and without successful sperm extraction were diagnosed by histopathology as having Sertoli cells only. The 16th patient with successful sperm retrieval had a histopathology of mixed atrophy and was diagnosed with Klinefelter syndrome. Conclusion: The presence of testicular microlithiasis is associated with low sperm retrieval rates among our cohort of men with non‐obstructive azoospermia undergoing scrotal ultrasonography prior to microsurgical testicular sperm extraction. Larger, prospective studies should be conducted to confirm these findings. [ABSTRACT FROM AUTHOR]

Introduction: Concurrent systematic biopsies during image-guided targeted biopsies of the prostate were found to improve the detection rate of clinically significant prostate cancer (CSPC). However, these biopsies do not routinely include anterior or apical sampling. We aimed to evaluate the significance of anterior and apical samplings during combined biopsies.Methods: After obtaining institutional review board approval we identified 303 consecutive patients who underwent transperineal combined biopsies of the prostate between 2017-2020. Systematic biopsies were obtained from the peripheral zone, anterior zone, and apex. Study outcomes included CSPC and any cancer on anterior or apical biopsies. Logistic regression analyses were used to evaluate the association between pre-biopsy characteristics and study outcomes.Results: Median prostatic-specific-antigen value was 6.8 ng/dL. Most patients had stage T1c disease (77%). Overall, combined biopsies detected CSPC in 87 patients (29%). Any cancer and CSPC in the anterior zone were found in 54 (18%) and 19 (6%) patients, respectively. Any cancer and CSPC in the apex were found in 54 (18%) and 16 (5%) patients, respectively. Anterior/apical samplings upgraded the pathological result in 19 patients (6%). Logistic regression analyses demonstrated that PI-RADS 5 lesions predicted the presence of CSPC in both the anterior zone (OR = 8, 95%CI = 3-22, P <0.001) and apex (OR = 4, 95%CI = 1-10, P = 0.01).Conclusions: Avoiding anterior and apical samplings during prostate biopsy does not result in substantial under-diagnosis of significant cancer. However, these areas are easily accessible using the transperineal approach and should be sampled in selected patients, particularly those with PI-RADS 5 lesions. [ABSTRACT FROM AUTHOR]
