Study summary

Prostate embolization is an alternative treatment to trans urethral prostate resection in the context of benign prostatic hypertrophy. This embolization treatment is also of interest in patients with chronic anuria surveyed in relation to their prostatic hypertrophy for disundation. This survey causes discomfort and urinary tract infection. It is a population with tortuous arteries, a severe atherosclerotic overload making embolizations complex and long. Often, only unilateral embolization is possible. The purpose of this study is to compare the effectiveness in terms of disundation of unilateral vs. bilateral embolization of the prostatic arteries

Prostate embolization is an alternative treatment to trans urethral prostate resection in the context of benign prostatic hypertrophy. This embolization treatment is also of interest in patients with chronic anuria surveyed in relation to their prostatic hypertrophy for disundation. This survey causes discomfort and urinary tract infection. It is a population with tortuous arteries, a severe atherosclerotic overload making embolizations complex and long. Often, only unilateral embolization is possible. The purpose of this study is to compare the effectiveness in terms of disundation of unilateral vs. bilateral embolization of the prostatic arteries.

Method of observation or investigation chosen:

Retrospective, observational collection with division of patients into two groups according to unilateral or bilateral embolization of the porstatic arteries.

Origin and nature of the data Patient's medical record: imaging stored in the PACS to confirm unilateral or bilateral embolization, perform measurements of prostate volume, urological medical record to see the effectiveness of embolization in terms of disundation, comfort of life, tolerance of embolization, effectiveness in terms of urination (IPSS score)

Data flow mode:

Data stored in redcap.
