RESUMO

This article was previously presented as an abstract at the 18th UAA Congress, Seoul, October 15-17, 2020, and the abstract was published in The International Journal of Urology. It was also presented as an e-poster at the 2021 BAUS Annual Meeting on June 22, 2021. Introduction In frail patients intractable hematuria secondary to advanced pelvic malignancies is a clinical challenge. Super-selective TAE of the vesical arteries is a suitable minimally invasive option. We present our experience in this patient cohort. Patients and methods All patients who underwent TAE from January 2014 to December 2019 were included. Super-selective TAE of the superior and inferior vesical arteries was done using 300-500µ polyvinyl alcohol (PVA) particles. Demographic data, cancer stage, associated urinary system obstruction, pre-embolization palliative treatment, chemotherapy, and radiotherapy were recorded. Technical and clinical success, time to cessation of hematuria, recurrence of hematuria, and complications were recorded. Data are presented as mean ± standard deviation, and statistical significance is set at p<0.05. Results From 2014 to 2019, seven patients underwent eight procedures. The average patient's age was 60.6±10.3 years. All presented with gross hematuria, six due to locally advanced and/or metastatic bladder cancer, and one due to prostate cancer. The average time of hematuria clearance was 60 hours. The average hemoglobin levels at the time of the procedure, one month, and six months post-embolization were 9.6±1.7 g/dL, 10.6±1.5 g/dL (p<0.05), and 9.6±0.9 g/dL, respectively (p>0.05). Packed red blood cell (PRBC) requirements decreased from 7±2 units to 5±3 units after the procedure (p >0.05). The patients were followed up for an average of 13.6 months and four had a recurrence at an average of four months post-embolization. Conclusion Super-selective TAE is an effective palliative method in controlling intractable hematuria. The risks of major surgery and anesthesia are omitted, and the procedure can be repeated as needed. Furthermore, post-embolization complications, using this technique, are minor and manageable.

RESUMO

OBJECTIVE: Testicular torsion is a common urological emergency, mainly in the younger population. Our aim is to evaluate the efficacy and value of testicular echogenicity in predicting testicular viability. METHODS: Patients who were older than 13 years of age and were discharged with the diagnosis of testicular torsion were reviewed. Data obtained included demographic data, history, physical examination results, ultrasound findings including size, color Doppler flow, and echotexture, torsion degrees, and surgical procedure. In addition, the histopathological findings of patients who underwent orchiectomy were reviewed. RESULTS: A total of 71 cases were diagnosed with testicular torsion between January 2016 to December 2018. The mean age at presentation was 20.4±7.0 years. The average time from the onset of pain until the presentation was 36.0±55.1 h. Out of the 71 ultrasound scans reviewed, 45.1% showed homogenous echotexture and 54.9% showed heterogeneous echotexture of the affected testis. On scrotal exploration, the mean degree of torsion was 475.7±301.8 degrees; 66.2% of the patients had a viable testis; and bilateral orchidopexy was done. The remaining 33.8% had a non-viable testis. Homogenous echotexture was after an average of 13.5 h of scrotal pain, while heterogeneous echotexture presented after 53.7 h of scrotal pain. There was a statistically significant difference between the time of presentation and echotexture changes on scrotal ultrasonography (p<0.01). The relationship between echotexture changes and testicular viability was statistically significant as well (p<0.001). CONCLUSION: A long time since the onset of pain coupled with heterogeneous changes in testicular parenchyma is a good indicator of non-viability. However, we still advocate for surgical exploration as the gold standard in diagnosis and management.
