Radical prostatectomy remains the gold-standard surgical treatment for clinically localized prostate cancer. Contrast imaging of the upper urinary tract is not part of the routine work-up of the patient before radical prostatectomy. This may lead to rare, albeit serious complications when anatomical anomalies are present. This article reports a case of delayed anastomotic leakage following radical prostatectomy due to an unrecognized duplex system on the left side and inclusion of the ureteric orifice draining the upper moiety in the anastomosis, which caused failure of healing and persistent leakage.

Purpose: To develop and validate a prostate-specific membrane antigen (PSMA) PET/CT based multimodal deep learning model for predicting pathological lymph node invasion (LNI) in prostate cancer (PCa) patients identified as candidates for extended pelvic lymph node dissection (ePLND) by preoperative nomograms.
Methods: [Ga]Ga-PSMA-617 PET/CT scan of 116 eligible PCa patients (82 in the training cohort and 34 in the test cohort) who underwent radical prostatectomy with ePLND were analyzed in our study. The Med3D deep learning network was utilized to extract discriminative features from the entire prostate volume of interest on the PET/CT images.

To compare the diagnostic value of fluorine 18-labelled prostate-specific membrane antigen (PSMA) PET/CT PRIMARY score and PSMA expression score for clinically significant prostate cancer (csPCa). The data of 70 patients with prostate cancer who underwent radical prostatectomy at Beijing Hospital from February 1, 2019 to February 29, 2024 were retrospectively analyzed. All patients underwent whole body F-PSMA PET/CT examination before surgery and pathological large sections of prostate specimens were made after surgery.
View Article and Find Full Text PDFIntroduction: The occurrence of Gleason grade group upgrading (GGU) significantly impacts both treatment strategy development. We aim to develop an optimal predictive model to assess the risk of GGU in patients with localized prostate cancer (PCa), by comparing traditional logistic regression (LR) with seven machine learning algorithms.
Methods: A retrospective collection of clinical data was conducted on patients who underwent RP at Wuhan Central Hospital (January 2017 to December 2023, n=177) and Jiangxi Cancer Hospital (July 2019 to February 2024, n=87).
Introduction: To determine the impact of diabetes and antidiabetic medications on referral and pathological outcomes in uro-oncology cases. We report preliminary results from a single center study.
Methods: We retrospectively collected data from 781 patients treated between 2018 and 2023 for radical prostatectomy (RP) for prostate cancer (PCa), radical cystectomy (RC) for bladder cancer (BCa), radical nephroureterectomy (RNU) for upper tract urothelial carcinoma, partial nephrectomy (PN) and radical nephrectomy (RN) for renal cell cancer (RCC).
