Th. aim.of th.s study was to present th. epidem.ological, clinical and th.rapeutic aspects of adult urological cancers in th. departm.nt of urology at Zinder National h.spital. Patients and m.th.ds: Th.s was a cross-sectional study of adult prim.ry urologic cancers during th. period of January 2019 to Decem.er 2023. Data were obtained from.th. record of patients adm.tted to urology, and th. m.dical oncology departm.nt. Th. param.ters studied were;frequency, age, sex, urogenital distribution, anatom.path.logical type, and th.rapeutic aspects. Data were recorded on Excel 2013 and analyzed with.Epi-info version 7.2.5. Results: Epidem.ology: About 289 cancers were diagnosed th.ough.6017 consultations during th. period, corresponding to 4.80% of urological path.logies: prostate cancer (n = 221;76.47%), bladder cancer (n = 46;15.92%), kidney cancer (n = 13;04.5%), testis cancer (n = 09;03.11%). m.dian age of patients was 50.42 years. Prostate cancer: was Adenocarcinom. in 100% (n = 221) with.Gleason scores > 7 (77.83%) and prostatique specific antigen (PSA) > 20 ng/m. in 90.04%. Extension evaluation 134 cases (60.63%). Treatm.nt was ch.rurgical castration in (62.44%) and resistance to castration appeared between 8 and 11 m.nth.. h.spital m.rtality for prostate cancer was 16.29%. Bladder cancer was found in 46 cases with.Sex ratio 7/1. Cystoscopy was perform.d for all. h.stology revealed squam.us cell carcinom. (n = 41;89.13%), and (n = 5;10.87%) uroth.lial. Endoscopic resection perform.d (n = 14;30.43%). Kidney cancers were 13 cases (10 m.n, 03 wom.n). Neph.ectom. was perform.d in (n = 8;61.54%) cases and h.stology revealed renal cell cancer in 76.92%. Testicular cancers were diag 09 cases. h.story of cryptorch.dism.was found in 4 cases, 4-year infertility in 3 cases. Orch.dectom. was done in all cases. Ch.m.th.rapy in 3 cases.
