Introduction: The COVID-19 pandemic has delayed screening, diagnostic workup, and treatment in prostate cancer (PCa) patients. Our purpose was to review PCa screening, diagnostic workup, active surveillance (AS), radical prostatectomy (RP), radiotherapy (RT), androgen deprivation therapy (ADT) and systemic therapy during the COVID-19 pandemic. Materials and Methods: We performed a systematic literature search of MEDLINE, EMBASE, Scopus, LILACS, and Web of Science, according to Preferred Reporting Items for Systematic Reviews and Meta-analyses Protocols (PRISMA-P) statement for relevant material published from December 2019 to February 2021. Results: Prostate biopsy can be delayed, except when high-risk PCa is suspected or the patient is symptomatic. Active surveillance is appropriate for patients with very low risk, low risk (LR) and favorable intermediate risk (FIR). RP and RT for high risk and very high risk can be safely postponed up to 3 months. Hypofractionated external beam RT (EBRT) is recommended when RT is employed. ADT should be used according to standard PCa-based indications. Chemotherapy should be postponed until the pandemic is contained. Conclusions: The international urological community was not prepared for such an acute and severe pandemic. PCa patients can be adequately managed according to risk stratification. During the COVID-19 pandemic, LR and FIR patients can be followed with active surveillance. Delaying RP and RT in high risk and locally advanced disease is justified.

microscopy were performed for surface and ultrastructural analysis. Glutathione assay, sodium uptake function and albumin uptake assay were performed to evaluate cellular function.RESULTS: Primary renal cells isolated from both normal kidneys (NK) and diseased kidneys (CKD) showed similar phenotypic characteristics and growth kinetics. The expression levels of renal tubular cell markers, Aquaporin-1 and E-Cadherin, and podocyte-specific markers, WT-1 and Nephrin, were similar in both NK and CKD kidney derived cells. Using fluorescenceactivated cell sorting (FACS), specific renal cell populations were identified and included proximal tubular cells (83.1 % from NK and 80.3 % from CKD kidneys); distal tubular cells (11.03 % from NK and 10.9 % from CKD kidneys); and podocytes (1.91 % from NK and 1.78 % from CKD kidneys). Ultra-structural analysis using scanning electron microscopy (SEM) revealed microvilli on the apical surface of cultured cells from NK and CKD samples. Moreover, transmission electron microscopy (TEM) analysis showed a similar organization of tight junctions, desmosomes, and other intracellular structures. The Na þ uptake characteristics of NK and CKD derived renal cells were also similar (24.4 mmol/L and 25 mmol/L, respectively) and no significant differences were observed in the protein uptake and transport characteristics of these two cell isolates.CONCLUSIONS: These results show that primary renal cells derived from diseased kidneys such as CKD have similar structural and functional characteristics to their counterparts from a normal healthy kidney (NK) when grown in vitro. This study suggests that cells derived from diseased kidney may be used as an autologous cell source for renal cell therapy, particularly in patients with CKD or end-stage renal disease (ESRD).
