Our results showed that observation could be considered for patients with asymptomatic lower pole stones. However, patients should be counseled about the 33% disease progression and 11% intervention rates.

Due to the widespread usage of prostate-specific antigen screening, the number of patients diagnosed with prostate cancer is steadily increasing. Many factors such as high operating room demand, insurance reimbursement, patients' desire to assess multiple treatment options, and anxiety can cause delays in radical treatment. In this study, we examined the effect of delay from prostate biopsy to surgery on outcomes of men with localized prostate cancer. Materials and Methods: The data of 359 patients who underwent radical prostatectomy (RP) in our clinic between 2008 and 2017 were analyzed retrospectively. Surgical delay was defined as the time from transrectal ultrasound-guided prostate biopsy to surgery. Patients were divided into 3 groups according to the interval between prostate biopsy and RP (≤60, 61-120, ≥120 days) and classified according to the D'Amico risk classification. Results: A total of 248 patients were included in the study. Of these patients, 107 (43.1%) were operated within 60 days of biopsy, 113 (45.6%) 61-120 days after biopsy, and 28 (11.3%) over 120 days after biopsy. Statistical analysis of patients with follow-up of at least 12 months did not reveal a significant difference between the groups in terms of biochemical recurrence (p=0.06). A delay of over 120 days was not associated with adverse pathological or oncological findings at surgery for the low-risk group. Extraprostatic invasion increased significantly in the intermediate-risk group with longer surgical delay (p=0.044). Conclusion: Our data demonstrated that a delay of more than 120 days was not associated with adverse pathological outcomes in men with low-risk localized prostate cancer. For men with intermediate-risk disease, delays over 60 days were significantly associated with risk of extraprostatic invasion. Our findings indicate that RP should be performed within 60 days of biopsy for intermediate-risk patients.

The yield of extended 14-core repeat biopsy protocol was higher in patients with previous negative sextant biopsy compared to the patients with previous negative 10-core biopsy. HGPIN history found on previous sextant biopsy was a strong cancer predictor on repeat biopsy; same was not true for the patients with previous 10-core biopsy. The yield of lateral peripheral cores and TZ biopsies were lower in patients with prior negative extended biopsy.
