RESUMO
Background: It is estimated that 75% of urothelial bladder cancers are non-muscle-invasive cancers (NMIBCs). The development of more effective methods for optimizing the management of this subset of patients is of paramount importance. This study aimed to evaluate the effectiveness and side effects of modified maintenance Bacillus Calmette-Guérin (BCG) therapy in patients with high-risk NMIBC. Methods: A total of 84 patients with NMIBC who met the inclusion criteria were randomly divided into 2 groups of 42 patients after receiving intravesical BCG weekly, 1 month after transurethral resection of the bladder tumor (TURT) for 6 weeks as the induction. In group I, patients continued monthly intravesical instillation of BCG for 6 months as maintenance, whereas group II patients did not. All patients were followed up for recurrence and progression for 2 years. Results: Although the recurrence rate was lower in group I (16.7% vs 31%), there was no significant difference among groups (P = .124). Pathology progression was also lower in group I (7.1% vs 11.9%) with no significant difference among groups (P = .713). Complications were not statistically different among groups (P = .651). A statistically significant difference was not observed between the groups in the acceptance rate of patients (97.6% in group I vs 100% in group II). Conclusions: The recurrence rate and progression rate in NMIBC patients with maintenance-free induction therapy after TURT were almost twice as high as those with 6-month maintenance therapy; however, it was not statistically significant. Modified BCG maintenance protocol made favorable compliance for patients. Trial registration: This study was retrospectively registered at Iranian Registery of Clinical Trials with the code IRCT20220302054165N1.
RESUMO
In this rapid review, we aimed to evaluate the effect of coronavirus disease 2019 (COVID-19) on renal functions and mortality of patients with kidney diseases. We searched MEDLINE, The Cochrane Library, Scopus, Embase, Web of Science, UpToDate, and TRIP databases using the following keywords: COVID-19, COVID19, 2019-nCoV, 2019-CoV, coronavirus, SARS-nCoV-2, urology, cancer, bladder, prostate, kidney, trauma, stone, neurogenic, and reconstructive. The initial search resulted in 495 records. After the primary screening of titles, abstracts, and full texts and removing duplicates, 10 articles were selected and included in this rapid review. Moreover, we performed meta-analysis of binary data for the outcomes with sufficient data. Owing to a high level of heterogeneity because of different study designs and contexts, we used a random model for the meta-analysis. Only 5 studies were eligible for the meta-analysis. In these studies, comprising 964 COVID-19 positive patients, the cumulative event rate of acute kidney injury (AKI) was 7.1% (95% confidence interval: 1.8%-24.5%, p<0.001, I2=92.4). Based on the qualitative synthesis of the 10 included studies, patients with COVID-19 and kidney diseases had higher risk of in-hospital mortality. If AKI occurs because of the novel coronavirus, the mortality rate will be very high. Therefore, we need further investigations and more studies to recognize the extent and the cause of renal involvement in COVID-19.
RESUMO
Epididymal agenesis is defined as the absence of the epididymis totally or segmentally, unilateral or bilateral, which is secondary to the Wolffian duct malformation (1). Rete testis, epididymis, vas deferens and seminal vesicle are believed to develop from Wolffian ducts.
