Inclusion Criteria: * STEP 1 REGISTRATION AND RANDOMIZATION * Patients must be \>= 18 years of age * Patient must have the ability to understand and the willingness to sign a written informed consent document. Patients with impaired decision-making capacity (IDMC) who have a legally authorized representative (LAR) or caregiver and/or family member available will also be considered eligible * Patient must have a diagnosis of high grade upper tract urothelial carcinoma expected within 14 weeks (98 days) prior to registration/randomization with one of the following: * Biopsy (gold standard, preferred) and either upper urinary tract mass on cross-sectional imaging or tumor directly visualized during upper urinary tract endoscopy * High grade cytology and clinically estimated invasive upper urinary tract mass on cross-sectional imaging (e.g., including presence of tumor-related hydronephrosis) or tumor directly visualized during upper urinary tract endoscopy * NOTE: Universal histologic testing of UTUC with additional studies, such as immunohistochemistry and/or microsatellite instability, is strongly recommended to identify patients with high probability of Lynch-related or other germline mutation related cancers whom clinicians should refer for genetic counseling and germline testing (this is not required for eligibility) * Due to the anatomy of upper urinary tract and lack of muscularis propria, pathologic evidence of cT2 on biopsy is usually not possible * Patients must not have any component of small cell/neuroendocrine carcinoma. Other histologic subtypes (variants) are permitted provided the half or predominant (\>= 50%) subtype is conventional urothelial carcinoma * Leukocytes \>= 3,000/mcL (obtained =\< 14 days prior to registration/randomization) * Platelets \>= 100,000/mcL (obtained =\< 14 days prior to registration/randomization) * Total bilirubin =\< 1.2 mg/dL (or ≤ 2 mg/dL for patients with Gilbert's disease) * Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase \[SGOT\]) and alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase \[SGPT\]) =\< 2 x institutional ULN (obtained =\< 14 days prior to registration/randomization) * Hemoglobin (Hgb) \>= 9 g/dL (obtained =\< 14 days prior to registration/randomization) * NOTE: Packed red blood transfusion is allowed to achieve this parameter as per treating investigator * Patients must not be pregnant or breast-feeding due to the potential harm to an unborn fetus and possible risk for adverse events in nursing infants with the treatment regimens being used. All patients of childbearing potential must have a blood test or urine study within 14 days prior to registration to rule out pregnancy.

Prior systemic immune checkpoint inhibitor is not allowed. * Patient with history of \>= pT4b, N+, and/or M1 UC is not eligible. * NOTE: Patients in whom concomitant or prior bladder/urethra predominant (\>= 50%) urothelial carcinoma have been surgically resected and demonstrated to be only Ta or carcinoma in situ (CIS) (\< cT1 N0) are eligible regardless of time elapsed * Patient must not have any uncontrolled illness including, but not limited to, ongoing or active infection including tuberculosis (clinical evaluation that includes clinical history, physical examination and radiographic findings, and tuberculosis testing in line with local practice), symptomatic congestive heart failure (CHF), myocardial infarction (MI) or unstable angina pectoris, significant uncontrolled cardiac arrhythmia, clinically relevant liver cirrhosis, interstitial lung disease, or psychiatric illness/social situations in the three months prior to registration that would limit compliance with study requirements * Patient must not have received prior radiation therapy to \>= 25% of the bone marrow for other diseases * Patient must not have received prior systemic anthracycline therapy * NOTE: Patients who have received prior intravesical therapy at any time for non-muscle invasive urothelial carcinoma of the bladder are eligible * Patient must not have either history of or active autoimmune disease requiring immunosuppressive therapy within 2 years prior to registration/randomization or any history of inflammatory bowel disease (inflammatory bowel disease \[IBD\], e.g. ulcerative colitis, or Crohn's disease), neuromuscular autoimmune condition, immune-related pneumonitis or interstitial lung disease. Patients with well-controlled hyper/hypothyroidism, celiac controlled by diet alone, diabetes mellitus type I, vitiligo, alopecia, psoriasis, eczema, lichen planus, or similar skin/mucosa condition are eligible * Patient must not be on or have used immunosuppressive medication within 14 days prior to the first dose of durvalumab. The following are exceptions to this criterion and are allowed: * Intranasal, inhaled, intra-auricular, topical steroids, or local steroid injections (e.g. intra-articular injection * Systemic corticosteroids at physiologic doses not to exceed 10 mg/day of prednisone or its equivalent at the time of enrollment * Steroids as pre-medications for hypersensitivity reactions (e.g. computed tomography \[CT\] pre-medication) * Human immunodeficiency virus (HIV)-infected patients on effective anti-retroviral therapy with undetectable viral load within 6 months prior to registration/randomization are eligible for this trial * NOTE: These patients must be stable on their anti-retroviral regimen with evidence of at least two undetectable viral loads within the past 6 months on the same regimen; the most recent undetectable viral load must be within the past 12 weeks. They must have a CD4 count of greater than 250 cells/mcL over the past 6 months on this same anti-retroviral regimen and must not have had a CD4 count \< 200 cells/mcL over the past 2 years, unless it was deemed related to the cancer and/or chemotherapy induced bone marrow suppression. They must not be currently receiving prophylactic therapy for an opportunistic infection and must not have had an opportunistic infection within the past 6 months * NOTE: For patients who have received chemotherapy in the past 6 months, a CD4 count \< 250 cells/mcL during chemotherapy is permitted as long as viral loads were undetectable during this same chemotherapy.

Patients who are cisplatin-eligible will be randomized to either Arm A or Arm B and patients who are cisplatin-ineligible will be registered to Arm C * Patients that meet any of the following four criteria will be registered to the cisplatin-ineligible Arm C if they meet other eligibility criteria: * Creatinine clearance \> 15 ml/min and =\< 50 ml/min (estimated by Cockcroft-Gault formula) or GFR \> 15ml/min/1.73m\^2 and ≤ 50 ml/min/1.73 m\^2 * Hearing loss \>= 3 * Neuropathy \>= 2 * ECOG performance status 2 * In addition, the patient must have an absolute neutrophil count (ANC) \>= 1,000/mcL obtained =\< 14 days prior to registration * Patients that meet all of the following four criteria will be randomized to the cisplatin-eligible Arm A or Arm B: * Creatinine clearance \> 50ml/min (estimated by Cockcroft-Gault formula) or GFR \> 50ml/min/1.73m\^2 * ECOG performance status 0-1 * Hearing loss grade 0-2 * Neuropathy 0-1 * In addition, the patient must have an absolute neutrophil count (ANC) \>= 1,500/mcL obtained =\< 14 days prior to randomization * Also, the patient must have left ventricular ejection fraction (LVEF) \>= 50% by (either multigated acquisition scan \[MUGA\] or 2-D echocardiogram) obtained within obtained within 28 days prior to randomization
