ABSTRACT
Objectives: The effect of physical activity on prostate cancer is controversial. We aimed to investigate the effect of physical activity on prostate cancer detection and functional outcomes after radical prostatectomy. Methods: Between 2019 and 2020, 166 patients who underwent prostate biopsy were included. The physical activity scores of patients were evaluated by the Physical Activity Scale for the Elderly (PASE) questionnaire before the procedure. PASE scores were compared between the patients with and without prostate cancer and local and metastatic aggressiveness of cancer. Patients who underwent radical prostatectomy were followed up for 12 months to analyze the effect of physical activity on erectile dysfunction (ED) and urinary incontinence (UI). Results: There was no significant difference between patients with and without prostate cancer in terms of PASE scores (187.7 vs. 195.5, p=0.665). PASE scores were also similar when separated according to D'Amico risk classification and metastatic events. Twenty-seven patients who underwent radical prostatectomy were evaluated in terms of functional outcomes at the first year of surgery. PASE scores of the patients with severe ED were lower than mild-moderate ED, but no statistically significant difference was observed (197.0 vs. 268.5, p=0.267). Patients with persistent UI had a significantly lower PASE score overall than continent patients (128.3 vs. 271.1, p=0.001), and PASE score was the only independent predictor of UI following radical prostatectomy. Conclusion: The effect of physical activity on prostate cancer development or aggressiveness could not be determined. Physical activity was associated with a reduced risk of UI following radical prostatectomy.
ABSTRACT
The prevalence of penile calcification in the population remains uncertain. This retrospective multicenter study aimed to determine the prevalence and characteristics of penile calcification in a large cohort of male patients undergoing non-contrast pelvic tomography. A total of 14 545 scans obtained from 19 participating centers between 2016 and 2022 were retrospectively analyzed within a 3-months period. Eligible scans (n = 12 709) were included in the analysis. Patient age, penile imaging status, presence of calcified plaque, and plaque measurements were recorded. Statistical analysis was performed to assess the relationships between calcified plaque, patient age, plaque characteristics, and plaque location. Among the analyzed scans, 767 (6.04%) patients were found to have at least one calcified plaque. Patients with calcified plaque had a significantly higher median age (64 years (IQR 56-72)) compared to those with normal penile evaluation (49 years (IQR 36-60) (p < 0.001). Of the patients with calcified plaque, 46.4% had only one plaque, while 53.6% had multiple plaques. There was a positive correlation between age and the number of plaques (r = 0.31, p < 0.001). The average dimensions of the calcified plaques were as follows: width: 3.9 ± 5 mm, length: 5.3 ± 5.2 mm, height: 3.5 ± 3.2 mm, with an average plaque area of 29 ± 165 mm² and mean plaque volume of 269 ± 3187 mm³. Plaques were predominantly located in the proximal and mid-penile regions (44.1% and 40.5%, respectively), with 77.7% located on the dorsal side of the penis. The hardness level of plaques, assessed by Hounsfield units, median of 362 (IQR 250-487) (range: 100-1400). Patients with multiple plaques had significantly higher Hounsfield unit values compared to those with a single plaque (p = 0.003). Our study revealed that patients with calcified plaques are older and have multiple plaques predominantly located on the dorsal and proximal side of the penis.
ABSTRACT
OBJECTIVE: Renal cell carcinoma is constantly associated with calcification, but ossification is extremely scarce. METHOD: We retrospectively analyzed two cases with clear cell renal cell carcinoma with osseous metaplasia. RESULTS: We criticized the oldest case of woman whose a 32x31mm irregular renal mass with calcifications and we also mentioned about a diffusely calcified mass of 90 mm of a 68-year-old male patient. The histopathological examinations of both were reported as clear cell carcinoma with metaplastic bone formation. CONCLUSION: Although there are no definitive data on prognosis and follow-up due to the low number of cases; this entity usually occurs with early stage disease and a favorable prognosis as in our cases. While the prognostic importance of osseous metaplasia existence in renal cell carcinoma is controversial, such that can safely be managed with nephron sparing surgery in appropriate cases. As the number of cases and follow-up periods increased; more definitive information will be obtained.
OBJETIVO: El carcinoma de células renales se asocia constantemente con la calcificación, pero la osificación es extremadamente escasa. MÉTODO: Analizamos retrospectivamente dos casos del carcinoma de células renales de células claras con metaplasia ósea. RESULTADOS: Criticamos el caso más antiguo de una mujer cuya masa renal irregular era de 32x31 mm con calcificaciones y también mencionamos una masa calcificada de forma difusa de 90 mm de un paciente masculino de 68 años. Los exámenes histopatológicos de ambos demostraron que se trataba del carcinoma de células claras con formación de hueso metaplásico. CONCLUSIÓN: Aunque, debido al bajo número de casos, no hay datos definitivos sobre el pronóstico y el seguimiento; esta entidad generalmente ocurre en un estadio temprano de la enfermedad con un pronóstico favorable como en nuestros casos. Si bien la importancia pronóstica de la existencia de metaplasia ósea en el carcinoma de células renales es controvertida, puede manejarse de manera segura con cirugía conservadora de nefronas en los casos apropiados. Dado el hecho de que se aumentó el número de casos y períodos de seguimiento, se obtendrá más información definitiva.
