    Objective: This report examined the approaches to low-risk patients using the data from the Urologic Cancer Database -Prostate, Urooncology Association.Materials and Methods: In this study, there were 920 patients with low-risk prostate cancer according to the current guidelines of the European Urology Association. Patient data were obtained from the Urological Cancer Database -Prostate, the Turkish Urooncology Association (UroCaD-P) from records of the years 1995-2021. Ethics committee approval was obtained for this study to publish in the form of a database report.Results: Our study was conducted with 920 patients with low-risk prostate cancer. Therefore, at the time of diagnosis, all patients in the study were ISUP 1, had a prostate specific antigen (PSA) level lower than 10 ng/mL, and clinically T1-T2a. Surgical treatment was used in 750 (81.5%) of the patients. At the time patients were retrieved from the database for the study, 140 patients (15.2%) were in the active surveillance (AS) process. Thirty patients (3.2%) in the study received their local treatment as radiotherapy (RT). The mean age value at cancer detection in the study was 61.9. The mean ages of the patients who were under AS and who underwent radical prostatectomy (RP) were 61.3 and 61.7 years, respectively. In the RT group, the mean age was 66.7 years. The mean PSA value of the whole group was 5.81 ng/mL. While it was 5.94 in AS patients, it was calculated as 5.89 in patients who underwent radical surgery. The mean PSA value of the RT group was 5.40. The pathological upgrade was detected in 225 patients (30%) after surgery. Surgical margin positivity was in 160 of the patients (21.3%) who underwent surgery. In addition, 100 patients (13.3%) had extracapsular disease. The seminal vesicle invasion was detected in 25 patients (3.3%) after surgery.Conclusion: We predict that the incidence of low-risk prostate cancer will increase over time due to the aging of the population, the use of PSA, advances in imaging modalities, and increasing biopsy success rates. Therefore, the importance of the existence of multicentric databases containing this patient group is undeniable. More studies are needed with these databases, including both patient demographics and treatment outcomes. Hopefully, this database report will be an important step in this direction.

    Introduction: Ultrasound-guided prostate biopsy is the standard method for the diagnosis of prostate cancer. The aim of the present survey is to assess the variability in patient preparation and technique of ultrasound-guided prostate biopsy among Turkish Urologists. Materials and Methods: In July 2004, a questionnaire was sent out to e-mail addresses of the members of Urooncological Association, asking about the details of prostate biopsy protocol of the members. The survey consisted of multiple choice questions about the patient preparation and prostate biopsy technique. Responses were acquired via e-mail and analyzed in detail. Results: Thirty two urologists from 24 centers responded. The biopsy procedure was performed by the urologist only in 54.16% of the centers, both urologist and radiologist in 37.5%, and radiologist only in 8.33%. Transrectal route was the most common method for ultrasound-guided prostate biopsy. A half of the responders performed biopsy when PSA was greater than 4 ng/ml. All of the centers administered antibiotic and a half of them used enema before the procedure. Approximately 37% of responders did not administer any type of analgesia, but 29.1% of all responders administered a periprostatic nerve block for reducing pain during the procedure. Most urologists obtained 10 or 12 biopsy cores and only 20.8% of them obtained routine transitional zone biopsy during the initial biopsy session. Conclusion: This survey demonstrated that patient preparation and technique of ultrasound-guided prostate biopsy is not standardized among Turkish Urologists, and a guideline on prostate biopsy is needed.
