The use of penile prostheses in the management of priapism.

Priapism is a relatively uncommon condition that can result in erectile dysfunction (ED) and corporal fibrosis. Cases of prolonged priapism are particularly prone to ED, which arises when priapism is treatment refractory or had a delayed presentation. Due to the emergent nature of priapism, it behooves urologists to be familiar with all potential treatment modalities to minimize adverse outcomes. In this review paper, we aim to summarize the literature regarding the use of penile prosthesis (PP) implantation in the setting of ischemic priapism (IP). In some patients who present later or have prolonged initial treatment, early insertion of PP may be indicated.

Five-year follow-up of active surveillance for prostate cancer: A Canadian community-based urological experience.

INTRODUCTON: We assessed oncological outcomes of active surveillance (AS) using a community database and identified factors associated with disease reclassification on surveillance biopsy. METHODS: A retrospective review was performed on 200 men on AS. Prostate-specific antigen (PSA) was measured every 3 to 6 months. Prostate biopsies were performed every 1 to 4 years, and at the individual physician's discretion. Disease reclassification was defined as clinical T1 to cT2 progression, or histologically as >2 cores positive, Gleason score >6, or >50% core involvement on surveillance biopsy. Multivariate Cox regression analysis evaluated factors associated with disease reclassification. Kaplan-Meier survival curves were plotted. RESULTS: We assessed a heterogeneous cohort of 86 patients, with a median age 67.2 years, who received ≥1 surveillance biopsies. The median follow-up was 5.2 years. The median times to first and second surveillance biopsies were 730 and 763 days, respectively. Overall, 47% of patients were reclassified on surveillance biopsy after a median 2.1 years. Factors associated with disease reclassification were PSA density >0.20 (p < 0.0001, hazard ratio [HR] 4.55, 95% confidence interval [CI] 2.116-9.782) and ≥3 positive cores (p = 0.0152, HR 3.956, 95% CI 1.304-12.003) at diagnosis, and number of positive cores on surveillance biopsy. In total, 25 (29%) patients received delayed intervention, with a median time to intervention of 2.6 years. The median time on AS was 4.4 years, with an overall survival of 95% and prostate-specific survival of 100%. CONCLUSIONS: Our community study supports AS to reduce over-treatment of prostate cancer. PSA density >0.20 and ≥3 cores positive are associated with disease reclassification on surveillance biopsy.

Renal splenosis presenting as a renal mass.

Splenosis should be considered in the differential of any patient with a history of splenic trauma or removal and a solid enhancing mass near or within the kidney. Splenosis is the autotransplantation of splenic tissue associated with splenic trauma or surgery, and can be diagnosed preoperatively, avoiding unnecessary surgery.
