RESUMEN
Since December 2019, increasing attention has been paid to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) epidemic in Wuhan, China. SARS-CoV-2 primarily invades the respiratory tract and lungs, leading to pneumonia and other systemic disorders. The effect of SARS-CoV-2 in transplant recipients has raised significant concerns, especially because there is a large population of transplant recipients in China. Based on the current epidemic situation, this study reviewed publications on this virus and coronavirus disease 2019 (COVID-19), analyzed common features of respiratory viral pneumonias, and presented the currently reported clinical characteristics of COVID-19 in transplant recipients to improve strategies regarding the diagnosis and treatment of COVID-19 in this special population.
RESUMEN
OBJECTIVE: To explore the correlation between the parameters of prostate volume (PV) measured by transabdominal ultrasonography and urodynamic results in diagnosing bladder outlet obstruction (BOO). METHODS: 112 BPH patients aged 45-85 underwent transabdominal ultrasonography to measure the superior-inferior diameter (R1) anterior-posterior diameter (R2), and left-right diameter (R3). Urodynamic examination was conducted to record the maximum flow rate (Qmax), detrusor pressure at maximum urinary flow rate (Pdet. Qmax), and detrusor pressure at minimum urinary flow rate (Pdet. Qmin), Schafer grading and international prostate symptom score (IPSS) scores were calculated. Correlation analysis was performed. RESULTS: The PV, R1, R2, and R3 were (48 +/- 29) ml, (4.3 +/- 1.0) cm, (3.7 +/- 0.9) cm, and (5.2 +/- 0.8) cm respectively. The Qmax, Pdet. Qmax, Schafer score, and IPSS score were (6.2 +/- 3.2) ml/s, (56 +/- 41) cm H2O, 3.1 +/- 1.8 (0-6) and 23 +/- 2 (15-31) respectively. Logistic regression analysis showed that R1 (OR = 22.662, P = 0.000), PV (OR = 0.946, P = 0.008) , and Qmax (OR = 0.760, P = 0.013) were positively correlated with Schafer grading value. CONCLUSION: The parameters of PV measured by transabdominal ultrasonography are reliable to diagnose BOO due to BPH.
