Our case aims to present the partial nephrectomy of a horseshoe kidney with renal-cell carcinoma and cholecystectomy. Case Report: A sixty-year-old male patient was admitted to our outpatient clinic with a 3 cm suspicious mass in the horseshoe kidney that was detected during an attack of acute cholecystitis. Computed tomography revealed a heteroge- neous hypodense lesion containing millimetric calcific foci of 35x31x33 mm in size at the ventral middle part of the right kid- ney. Partial nephrectomy was performed non-ischemically and then cholecystectomy was performed. Pathological examination revealed stage T1a clear cell renal carcinoma, WHO/ISUP Grade 2 with a negative surgical margin. During follow-up; urea, creatinine, and glomerular filtration rate were found to be normal. Conclusion: Horseshoe kidneys are fairly common among renal anomalies. Cholecystectomy following non-ischemic partial nephrectomy for a tumor in the horseshoe kidney is a rare case.eninfo:eu-repo/semantics/openAccessHorseshoe kidneynephrectomycholecystectomyArticle73149153819253
