I had yearly checkups with a DRE by every uro at the time for BPH and a fluctuating, but slowly rising PSA. After my TURP for BPH, I had 6-month visits, with the DRE every other visit. When my uro felt a slight induration on one side, he wanted DREs every 6 months.
The induration disappeared on its own, but at a subsequent visit my uro felt a new nodule, which triggered my last biopsy. The nodule turned out to be negative (about
half of them do), but the prostate biopsy hit high-grade cancer elsewhere that required treatment.
I'd be surprised if the doctor skipping the DRE is a urologist. Only a small portion of the prostate can be felt with a DRE, but the size, consistency, and symmetry of the prostate can be monitored, along with other abnormalities.
The additive value of mpMRI on prostate cancer detection: Comparison between patients with and without a suspicious digital rectal examination (DRE) (2020)
"Diagnosis of prostate cancer (CaP) is based on digital rectal examination (DRE) and/or elevated prostate specific antigen (PSA) level. ... Therefore, the aim of our study is to investigate whether mpMRI provides similar advantages in detection of CaP according to the DRE findings.
...
Conclusions: Patients submitted to fusion biopsy and have a positive DRE are diagnosed more often with CaP, have higher grade disease and larger tumors. In patients suspicious for CaP and having a significant lesion on mpMRI one should combine targeted and systematic biopsy regardless of the DRE status."

"CONCLUSION Given the considerable lack of evidence supporting its efficacy, we recommend against routine performance of DRE to screen for prostate cancer
in the primary care setting."

IMO, one's attitude toward tests with negative results should not be "Well, once again, that sure was unnecessary!", but rather to say, after a positive test that provides early diagnosis: "That's unwelcome news, but thank you for the early diagnosis!" Do you really want to be in a position where metasatic PCa is diagnosed and you are asking yourself "Would I have known any earlier with a DRE?"
