Introduction:
Subcapsular renal hematoma after ureterorenoscopy using a holmium yttrium-aluminum-garnet laser is a rare complication. We experienced a case of subcapsular hematoma after ureterorenoscopy.
Case Presentation:
The patient was a 56-year-old man with a history of hypertension and coronary vasospastic angina, and he was taking antiplatelet drugs. He had the middle and lower calyx stones measured 36 mm in diameter of the right kidney. We performed ureterorenoscopy, which was completed about 2 h without intraoperative complications. We could not remove the stone completely. After the surgery, the patient developed a fever and complained of right back pain. Computed tomography showed several residual stones formed a stone street, obstructing the stent and resulting in grade 3 hydronephrosis. Furthermore, the right subcapsular renal hematoma infection had detected. Percutaneous hematoma drainage and percutaneous nephrostomy were performed.
Conclusion:
Subcapsular renal hematoma after ureterorenoscopy is an uncommon complication but should be kept in mind.
