Abstract
This study was conducted on 20 patients presented with severe urinary tract bleeding that required endovascular embolization The last few decades have seen the development of the basic applications of interventional radiology due to advancements in the equipments. Severe Urinary tract bleeding is the most clinical emergency in the genitourinary system that needs immediate intervention. Surgical intervention will have high risk of total nephrectomy. Minimally invasive percutaneous endovascular embolization is a good alternative for surgery in such cases.
This study was conducted on 20 patients presented with severe urinary tract bleeding that required endovascular embolization.
The causes of bleeding that needs intervention were divided into traumatic injuries or tumors. Iatrogenic renal injuries were the main cause of bleeding that needs intervention.
Investigations included Ultrasonography and Doppler examination, Multiphasic Renal MDCT, Conventional Renal Angiography for confirmation of the bleeding source.
the whole procedure was done under local anesthesia with getting femoral axis and renal artery angiogram followed by super-selective catheterization of the bleeding artery using microcatheter. the embolizing materials used were glue, coils or particles according to each case.
Short term follow-up showed clinical success of the procedure which has been confirmed clinically by cessation of hematuria and improving the vital signs as well as stable HB level.
There was no serious complications post embolization. Only mild fever and moderate flank pain in three cases (15%) adequately managed by analgesic and antipyretics and one case presented with infected subcapsular hematoma after embolization and managed by US guided pigtail drainage and antibiotics.
