Prostate Artery Embolization Used in the Management of Transfusion-Dependent Hematuria After Prostatic Urethral Lift Procedure in a Patient with Thrombocytopenia: A Case Report.

Abstract

Background: The prostatic urethral lift (PUL) procedure is a novel therapeutic method to treat lower urinary tract symptoms (LUTS) caused by benign prostatic hyperplasia (BPH). Gross hematuria after this procedure has been reported to be mild and transient. This report highlights a case of refractory transfusion-dependent hematuria after the PUL procedure in addition to its management with selective prostatic arterial embolization (PAE). Case Presentation: A 78-year-old Caucasian man with a history of myelodysplastic syndrome, thrombocytopenia, and intermittent urinary retention secondary to BPH underwent a PUL procedure. Before the procedure he received a platelet transfusion making his platelet count 58,000/μL. The day after the procedure he was admitted to a hospital for gross hematuria with clot retention. He was started on continuous bladder irrigation and taken to the operating room for clot evacuation and fulguration of prostate. His thrombocytopenia and anemia were managed with transfusions. He was treated with desmopressin, aminocaproic acid, and intravesical 1% alum without improvement. He returned to the operating room for clot evacuation in addition to photoselective vaporization of the prostate laser ablation of the prostatic fossa. He eventually required a total of four transurethral fulgurations without improvement in transfusion-dependent hematuria. Ultimately, resolution of the hematuria was achieved through bilateral PAE with Embosphere^® Microspheres performed by interventional radiology. He was discharged home 2 days after the embolization procedure without recurrence of hematuria or urinary retention at a 6-month follow-up visit. Conclusion: The PUL procedure has been shown to be an effective alternative to more invasive surgical options for LUTS caused by BPH. Despite careful consideration in an attempt to alleviate urinary retention, PUL still resulted in significant bleeding in this patient with thrombocytopenia. This is the first report to highlight the use of bilateral PAE as a method for achieving control of severe refractory hematuria after PUL.
