RESUMEN

Phosphodiesterase type 5 inhibitors (PDE5Is) are the first-line therapeutic option for erectile dysfunction (ED), while second-line therapy includes the alprostadil. Due to the different pharmacodynamic mechanism of PDE5Is and alprostadil, a synergistic action is conceivable when they are administered in combination. The aim of present study was to evaluate the efficacy and safety of combination therapy with PDE5I and topical alprostadil in patients with ED non-responders to PDE5I alone. We designed a prospective, two-arm, open-label, non-randomized study. Patients over 18 years old, with a stable sexual relationship for at least 6 months, and ED non-responders to PDE5I monotherapy were included in the study. At baseline the variables assessed were 5-item version of the International Index of Erectile Function (IIEF-5), and Sexual Encounter Profile Questions 2 and 3 (SEP-2 and SEP-3). In addition, all subjects underwent penile dynamic duplex ultrasonography. All patients were assigned to the monotherapy group (Group A) or combination therapy group (Group B) based on their preference. Topical alprostadil 300 µg/100 mg (Virirec®) was the treatment assigned to Group A, while the combination therapy with the last PDE5I taken (at the maximum recommended dose) plus topical alprostadil 300 µg/100 mg (Virirec®) was assigned to Group B. After 3 months from assignment to groups were evaluated IIEF-5, SEP-2 and SEP-3 regarding the last sexual intercourse, and Global Assessment Questionnaire-Questions 1 and 2 (GAQ-1 and GAQ-2). All adverse events (AEs) that occurred during the study period were recorded. A total of 170 patients were included in the study (72 in Group A and 98 in Group B). Fifty-two patients were previously treated with sildenafil 100 mg (30.6%), 6 with vardenafil 20 mg (3.5%), 56 with tadalafil 20 mg (32.9%), and 56 with avanafil 200 mg (32.9%). No significant differences among the study groups were found at baseline (p > 0.05). The mean IIEF-5 score increased significantly in Group B after treatment compared to baseline (12.4 ± 3.4 vs. 17.1 ± 4.5; p < 0.001), conversely patients in Group A showed no significant increase (12.2 ± 2.5 vs. 12.7 ± 3.1; p = 0.148). The number of affirmative responses to SEP-2 was significantly higher after treatment compared to baseline only in Group B (57 vs. 78; p < 0.001). The number of affirmative responses to SEP-3 was significantly higher after treatment compared to baseline in both groups (p < 0.001). The number of affirmative responses to GAQ-Q1 and GAQ-Q2 was significantly higher in Group B compared to Group A (p < 0.001). A total of 59 (34.7%) patients experienced AEs. They were mild, self-limited, and did not cause discontinuation of treatment. No episode of priapism was recorded. No statistically significant difference was recorded between the AEs of the two groups, except for facial flushing that was reported only in Group B (p = 0.021). The combination therapy with topical alprostadil and PDE5I seems to be more effective than topical alprostadil alone without worsening the safety of the treatment.

RESUMEN

Glandular ischemia is an extremely uncommon dreaded postoperative complication of inflatable penile prosthesis surgery that may lead to penile gangrene and organ loss, whose incidence is difficult to determine. We report the case of a 56-year-old male admitted to our department with complaints of cold and painful glans penis after penile implant one month before. A color Doppler examination revealed the normal intracavernosal arteries with no vascularity in the superficial glans tissues. Due to the mild severity of the ischemia, conservative management was suggested, and consisted of oral pentoxifylline and hyperbaric therapy for 10 days, achieving a significant improvement at 4 months of follow-up.

RESUMEN

We present a case of an 83-year-old-male with painless penile nodules several months after he was diagnosed with pure prostatic small cell carcinoma. Penile doppler ultrasound and magnetic resonance imaging demonstrated solid nodules in both corpora cavernosa. Fine-needle aspiration of the nodules with immunohistochemical examination confirmed prostatic small cell carcinoma origin of metastases. Small cell carcinoma of the prostate is a rare disorder accounting for less than 1% of all prostate cancers, the penis being an uncommon site for metastasis. An extremely low number of cases of penile metastases from prostatic small cell carcinoma has been reported to date in the literature

Presentamos un caso de un varón de 83 años con nódulos peneanos indoloros, tras ser diagnosticado meses atrás de carcinoma prostático de células pequeñas puro. La eco-doppler e imagen de resonancia magnética de pene reflejaron nódulos sólidos en ambos cuerpos cavernosos. La aspiración con aguja fina de los nódulos con prueba inmunohistoquímica confirmó el origen metastásico del carcinoma de células pequeñas. El carcinoma prostático de células pequeñas es un trastorno inusual que representa menos del 1% de todos los cánceres prostáticos, siendo el pene un sitio infrecuente de metástasis. Hasta la fecha se ha reportado en la literatura un número de casos extremadamente bajo de metástasis peneanas en el carcinoma de próstata de células pequeñas

RESUMEN

INTRODUCCIÓN: La biopsia prostática por fusión se describe como superior a la biopsia transrectal sistemática para identificar lesiones sospechosas de carcinoma de próstata. OBJETIVOS: Evaluar la clasificación PIRADS propuesto por la Sociedad Europea de Radiología Urogenital para la detección de cáncer de próstata mediante RNM en una cohorte consecutiva de pacientes con RNM y biopsia guiada por fusión. MATERIAL Y MÉTODOS: Estudio observacional transversal. 87 pacientes con sospecha de cáncer de próstata sometidos a biopsia de próstata transperineal y fusión con RNM en nuestro centro. Describimos tumor significativo como Gleason ≥ 7(3 + 4), y carcinoma de alto riesgo como Gleason ≥ 8. Utilizamos la prueba de Chi-cuadrado para analizar la relación entre cáncer de próstata y PIRADS, así como regresión logística y pruebas de tendencia lineal, comparando las proporciones con medidas de intensidad de asociación. Empleamos el sistema HITACHI Real-Time Virtual Sonography y el software STATA/IC v.14.2 para el análisis estadístico. RESULTADOS: 64,37% pacientes presentaron resultado positivo para malignidad. Media de edad 67,89 años (SD 7,42), de PSA total 9,15 ng/ml (SD 7,85), y de volumen prostático 54,05 cc (SD 22,92). Se biopsiaron 124 lesiones sospechosas en RNM (25% PIRADS III, 57,26% PIRADS IV y 17,74% PIRADS V). 5/31 lesiones PIRADS III, 47/71 PIRADS IV y 18/22 PIRADS V fueron positivas para malignidad, con relación lineal estadísticamente significativa entre PIRADS y malignidad (p < 0,001), razón de prevalencias (RP) 4,10 (IC95% 1,81-9,32) para PIRADS IV, y RP 5,07 (CI95% 2,2211,59) para PIRADS V respecto a PIRADS III. 3,23% lesiones PIRADS III, 32,39% PIRADS IV y 63,64% PIRADS V correspondieron a tumores significativos. Encontramos asociación estadísticamente significativa entre PIRADS y tumores significativos (p < 0,001), RP 10,04 (IC95% 1,42-71,09) para PIRADS IV y RP 19,73 (IC95% 2,80139,18) para PIRADS V respecto a PIRADS III. CONCLUSIÓN: Nuestros resultados muestran que la biopsia de próstata ecodirigida y por fusión utilizando RNM es una técnica segura con excelentes resultados para obtener un diagnóstico preciso de cáncer de próstata, y puede mejorar el diagnóstico de malignidad y de tumores significativos reduciendo el sobrediagnóstico

INTRODUCTION: Prostate Fusion biopsy (MRI + prostate ultrasound) is described in literature as superior to classic random transrectal biopsy in order to identify suspicious lesion. OBJECTIVES: To evaluate the Prostate Imaging Reporting and Data System (PI-RADS) proposed by the European Society of Urogenital Radiology (ESUR) for detection of prostate cancer by multiparametric MRI in a consecutive cohort of patients with MRI and transrectal ultrasound prostate fusion-guided biopsy. MATERIAL AND METHODS: 87 patients with suspected Prostatic Cancer on prostate MRI underwent fusion transperineal prostate biopsy in our Department. 37 patients had at least one prior negative classic prostatic transrectal biopsy. Clinically significant tumor was described as Gleason 7(3+4) or higher. The Chi-square test was used to analyze the relationship between prostate cancer and the different PIRADS stages, as well as logistic regression and linear trend tests, comparing the proportions using measures of association intensity. We use the HITACHI Real-Time Virtual Sonography (HI-RVS) system, and the STATA/IC v.14.2 software for statistical analysis. RESULTS: 64.37% patients had tested positive for malignancy. Median age 67.89 years old. Median PSA 9.15 ng/ml, and average prostate volume was 54.05 cc. 124 suspicious lesions were described in prostate MRI (25% PIRADS III, 57% PIRADS IV and 17% PIRADS V). 5/31 lesions PIRADS III, 47/71 PIRADS IV and 18/22 PIRADS V were positive for malignancy, with a statistically significant linear relationship between PIRADS and malignancy (p < 0.001) - HR 4.10 (CI 95% 1.81 to 9.32) for PIRADS IV and HR 5.07 (CI95% 2.22 to 11.59) for PIRADS V vs. PIRADS III. 3.23% lesions PIRADS III, 32.39% PIRADS IV and 63.64% PIRADS V corresponded to significant tumors. A statistically significant association between PIRADS and significant tumors (p < 0.001) - HR 10.04 (CI95% 1.42 to 71.09) for PIRADS IV and HR 19.73 (CI95% 2.80 to 139.18) for PIRADS V vs PIRADS III was observed -. CONCLUSION: Our results show that transperineal targeted prostate biopsy using multiparametric MRI and transrectal ultrasound fusion is a safe procedure with excellent outcomes to obtain an accurate diagnosis of prostate cancer. Fusion biopsy has the potential to improve the diagnosis of malignancy and clinically significant tumors while reducing overdiagnosis

RESUMEN

Bladder cancer is a common cancer that may present as superficial, invasive, or metastatic disease. Non-muscle-invasive bladder cancer (NMIBC) represents the majority of bladder cancer diagnoses, but represents a spectrum of disease with a variable clinical course, notably for significant risk of recurrence and potential for progression. NMIBC metastasis to distant organs without local invasion or regional metastasis is a very rare occurrence, so there are limi-ted case reports about early metastasis in the literature.
