Gross hematuria as the presentation of ureteral paraganglioma: a case report and literature review

Abstract

Background Paraganglioma of genitourinary tract is uncommon, and origin from ureter is even rarer. We aim to present a case of paraganglioma from ureter in a 48-year-old female patient, who presented with gross hematuria. Case presentation We present a 48-year-old female who complained of gross hematuria for one week. A left ureteral tumor was found by image study. However, hypertension was unexpectedly recorded during diagnostic ureteroscopy survey. Due to persisted gross hematuria and bladder tamponade, she underwent left nephroureterectomy with bladder cuff resection. Blood pressure surged again when the tumor was surgically approached. Ureteral paraganglioma was confirmed according to pathological report. After the surgery, the patient recovered well, and no more gross hematuria was noted. She is now under regular follow-up at our outpatient clinic. Conclusion Ureteral paraganglioma should be kept in mind not only when blood pressure fluctuates during operation, but also before we manipulate the ureteral tumor when gross hematuria is the only sign. Whenever the presumption of paraganglioma is raised, laboratory evaluation and anatomical or even functional imaging should be considered. The concomitant anesthesia consultation before the surgery should not be deferred, either.
