Background/Objectives: Prostatic lymphoma is a rare malignant tumour that frequently causes urinary tract obstruction. It is uncommon for patients to present with systemic features or B-symptoms. As a result, it is often diagnosed incidentally during surgical lower urinary tract symptoms (LUTS) treatment. This systematic review aims to identify any common clinical features of prostatic lymphoma diagnosed incidentally during surgical LUTS treatment and summarise disease treatment and outcomes. Methods: The study protocol was registered with Prospective Register of Systematic Reviews (PROSPERO). A search was performed across the following electronic databases: MEDLINE, Embase, Web of Science, and Cochrane Database of Systematic Reviews. Full texts of eligible studies were analysed and data were extracted. The review was performed in accordance with PRISMA guidelines. Results: A total of 24 case reports compromising 25 cases were included. The median (IQR) age was 67 (61–73) years. All patients reported LUTS as their primary complaint, and the median duration of LUTS prior to diagnosis was 17 (4–44) months. Serum prostate-specific antigen (PSA) was normal in 10 cases and prostatomegaly present on imaging in 16 cases. A total of 10 different subtypes of lymphoma were reported. Extra-prostatic involvement was reported in eight patients. Chemotherapy, with or without adjuvant radiotherapy, was the mainstay of lymphoma treatment. The majority of articles reported positive outcomes, with complete remission in 17 cases. Conclusions: Prostatic lymphoma is a difficult clinical diagnosis due to its similar presentation to benign prostatic hyperplasia (BPH). Although rare, prostatic lymphoma may need to be considered as a diagnosis in patients with an atypical presentation of BPH. Prognosis is often favourable after prompt referral to haematology or oncology.
This study evaluated the hypothesis that 68Ga-PSMA-11 PET SUV, obtained via an advanced DL approach, correlates better with MR ADC maps than values from conventional PET-MR. Additionally, we aimed to identify the optimal SUV threshold for maximum correlation with ADC values. A cohort of 32 prostate cancer patients underwent CT and corresponding PET-MR imaging. The dataset underwent K-fold cross-validation, dividing it into four folds. In each fold, 24 patients were used for training, and 8 for validation to create DL models. ADC maps from 27 out of 32 patients were successfully aligned with T2 images for detailed analysis, revealing an inverse correlation (ρ = −0.20 to −0.51) between ADC and SUV values in prostate cancer zones. Statistically significant differences in mean SUV values were observed between PETMRI and PETDL. DL-based SUV values show a stronger correlation with ADC than conventional PET-MR values in our investigation.
Background/Objectives: Limited data exist on the outcomes of men with bladder stones undergoing cystolitholapaxy alone versus cystolitholapaxy with concurrent transurethral resection of the prostate (TURP). Additionally, factors associated with the need for subsequent TURP in these patients are not well defined. This study aimed to compare the clinical outcomes in men undergoing cystolitholapaxy alone with those undergoing concurrent cystolitholapaxy with TURP, and determine what factors were associated with the need for subsequent TURP. Methods: A retrospective review was conducted of men undergoing cystolitholapaxy at a single Australian hospital between 2014 and 2021. Patients were grouped into cystolitholapaxy alone (Group A) and cystolitholapaxy with concurrent TURP (Group B). Clinical outcomes compared included rates of acute urinary retention (AUR), urinary tract infection (UTI), and subsequent TURP. Prostate volume (PV), stone size, and the presence of intravesical prostatic protrusion (IPP) were evaluated as potential predictors of subsequent TURP in Group A. Results: Fifty men were included in the final analysis, with a median follow-up of 50 months (interquartile range [IQR] 24–81). Baseline characteristics did not differ significantly between groups. There was no statistically significant difference in the rates of AUR (11% vs. 13%) or UTI (22% vs. 30%) between Group A and Group B, respectively. However, 41% of Group A underwent subsequent TURP, compared to 9% in Group B (p = 0.0112). Within Group A, those requiring subsequent TURP had a significantly greater PV (65 vs. 34 cc, p = 0.0059), larger stone size (3.5 vs. 2.0 cm, p = 0.0175), and a higher prevalence of IPP (82% vs. 6%, p < 0.001). Conclusions: Cystolitholapaxy alone is a viable initial treatment for bladder stones, with comparable clinical outcomes to concurrent TURP. PV, stone size, and IPP may help identify patients likely to require future TURP, enabling more tailored treatment and potential reduction in TURP-related morbidity.
