Background and study aims
Inflammation (the body's response to cell damage) plays a critical role in many chronic diseases. In particular, in patients with cancer, it has been shown that the presence of a chronic inflammation status is involved in the development and progression of the tumour. For example, in urology, patients with chronic prostatic inflammation are at higher risk of urinary symptoms, urinary retention and need for prostate surgery.
The gold standard for the diagnosis of tissue inflammation is the examination of a tissue sample, which cannot always be performed for both ethical and procedural issues. For this reason, a lot of studies have tried to identify a blood test for inflammation. In recent years, many authors have highlighted some simple blood laboratory tests (such as blood cell count, albumin, count of platelet, fibrinogen, C reactive protein etc) that seem to help clinicians in the identification of patients at higher risk of complications and unfavourable outcomes after surgery.
The role of these inflammatory markers in the urological field is still unclear.
The design of the "IRU Study" expects to prospectively collect all the laboratory tests required in the preoperative evaluation phase of patients undergoing urological surgery procedures, in order to calculate the main inflammatory indexes and to look for the association of these with post-surgical outcomes.
Who can participate?
Patients older than 18 years undergoing urological surgery procedures.
What does the study involve?
A prospective survey of patients undergoing urological surgery procedures.
Patients will undergo the following clinical/instrumental assessments at baseline and at postoperative assessments:
• Historical and physical examination
• Blood sample
• Urine examination with urine culture and possible antibiogram
• Preoperative staging examinations for patients with cancer
• Preoperative routine diagnostic tests for benign diseases
• Intraoperative evaluation
• Histopathological analysis
Follow up for up to 5 years.
What are the possible benefits and risks of participating?
None
Where is the study run from?
European Urological Center (Italy)
Where is the study starting and how long is it expected to run for?
February 2021 to October 2026

| Scientific title | The role of inflammation in urological surgery |
| Study acronym | IRU STUDY |
| Study objectives | Inflammation plays a critical role in many chronic diseases. In the urological field, patients with chronic prostatic inflammation are at higher risk of severe voiding symptoms, acute urinary retention and prostate surgery. Blood laboratory tests, such as blood cell count, albumin, PLT, fibrinogen, CPR and PCT, seem to play a role in the identification of patients at higher risk of complications after surgical procedures. The aim of this study is to calculate the main inflammatory indexes for patients undergoing benign and malignant urological surgery in order to evaluate their association with post-surgical outcomes. |
| Ethics approval(s) | Approved 07/09/2021, Ethical Committee of Nord Area of Emilia Romagna Italian Health Care System (Via del Pozzo, 71 – 41124 Modena, Italy; +39 59-4224472; comitato.etico@pec.aou.mo.it), ref: 0026972/21 |
| Health condition(s) or problem(s) studied | Urological surgery procedures |
| Intervention | According to EAU guidelines and pre-hospitalization protocols, all eligible patients will undergo the following clinical/instrumental assessments: • Historical and physical examination • Blood sample • Urine examination with urine culture and possible antibiogram • Preoperative staging examinations for patients with cancer • Preoperative routine diagnostic tests for benign diseases • Intraoperative evaluation • Histopathological analysis Follow-up assessments will be performed according to the diagnosis and different kinds of surgical procedures. The duration of the study is 5 years |
| Intervention type | Other |
| Primary outcome measure(s) |
Inflammation indexes will be calculated by the neutrophils/lymphocytes, neutrophils/monocytes, lymphocytes/platelets, CPR, PCT, Albumin, fibrinogen, modified Glasgow prognostic score (mGPS) measured at the time of surgery and at post-operative evaluations using blood and urine samples |
| Key secondary outcome measure(s) |
Obtained by review of medical records at baseline and at follow up appointments: |
