Objectives To investigate the impact of implementing magnetic resonance imaging (MRI) and ultrasonography fusion technology on biopsy and prostate cancer (PCa) detection rates in men presenting with clinical suspicion for PCa in the clinical practice setting. Patients and Methods We performed a review of 1 808 consecutive men referred for elevated prostate‐specific antigen (PSA) level between 2011 and 2014. The study population was divided into two groups based on whether MRI was used as a risk stratification tool. Univariable and multivariable analyses of biopsy rates and overall and clinically significant PCa detection rates between groups were performed. Results The MRI and PSA‐only groups consisted of 1 020 and 788 patients, respectively. A total of 465 patients (45.6%) in the MRI group and 442 (56.1%) in the PSA‐only group underwent biopsy, corresponding to an 18.7% decrease in the proportion of patients receiving biopsy in the MRI group ( P < 0.001). Overall PCa (56.8% vs 40.7%; P < 0.001) and clinically significant PCa detection (47.3% vs 31.0%; P < 0.001) was significantly higher in the MRI vs the PSA‐only group. In logistic regression analyses, the odds of overall PCa detection (odds ratio [OR] 1.74, 95% confidence interval [CI] 1.29–2.35; P < 0.001) and clinically significant PCa detection (OR 2.04, 95% CI 1.48–2.80; P < 0.001) were higher in the MRI than in the PSA‐only group after adjusting for clinically relevant PCa variables. Conclusion Among men presenting with clinical suspicion for PCa, addition of MRI increases detection of clinically significant cancers while reducing prostate biopsy rates when implemented in a clinical practice setting.

Abstract Background Glanular hypermobility (GH) or supersonic transporter (SST) deformity are occasionally encountered during penile prosthesis (PP) implantation, yet management strategies are underreported with minimal data available on surgical outcomes. Aim To describe a modified technique for glanulopexy to correct GH/SST in men undergoing PP placement and assess outcomes associated with this technique. Methods Glanulopexy was performed in men with GH/SST identified at the time of or following PP placement. A modification to previously described techniques was performed, whereby a suture is passed into the glans and secured to the tissue overlying the corpora through small incisions on the lateral aspects of the distal penile shaft. Outcomes Correction of the anatomic deformity (GH/SST), device infection, and changes in penile sensation were evaluated during post-operative follow-up. Results From 2014–2017, a total of 12 patients underwent modified glanulopexy for GH/SST. Nine (75%) were performed at the time of PP, while the remaining 3 were performed in a delayed fashion. At a median follow-up of 12 months (range 1–33 months), all patients with the device in situ demonstrated appropriate glanular positioning, and no patients reported changes in penile sensation. A single patient required device removal secondary to infection. Clinical Translation Glanulopexy with permanent suture successfully corrects severe GH or SST in men with inflatable PP without reduced penile sensation. Conclusions Strengths of the current study include the description of a simple, safe, and reproducible technique for GH/SST that adds minimal operative time and can be performed under local anesthesia when necessary. To our knowledge, this represents one of the largest reported series of glanulopexy outcomes reported in the literature. Limitations include that this is a single-surgeon series, there is limited follow-up, and lack of a comparison group. Further study with external validation is warranted to establish the optimal role for the procedure.

Objective To evaluate whether elective off‐clamp laparoscopic partial nephrectomy ( LPN ) affords long‐term renal functional benefit compared with the on‐clamp approach. Patients and Methods This is a retrospective review of patients who underwent elective LPN between 2006 and 2011. Patients were followed longitudinally for up to 5 years. In all, 315 patients with radiographic evidence of a solitary renal mass and normal‐appearing contralateral kidney underwent elective LPN ; 209 were performed on‐clamp vs 106 off‐clamp. One patient who required conversion from LPN to open PN was excluded from the study. Additionally, four patients in the on‐clamp cohort who underwent subsequent radical nephrectomy for local‐regional recurrence were excluded from longitudinal functional evaluation after their procedure. The primary objective was to evaluate differences in postoperative estimated glomerular filtration rate ( eGFR ) between hilar clamping groups. Subgroup analyses were performed for patients with clamp times >30 min and those with baseline renal insufficiency ( eGFR <60 mL/min/1.73m 2 ). Risk of developing worsened or new‐onset renal insufficiency was also compared. Results The mean preoperative eGFR was similar between the on‐clamp and off‐clamp cohorts (80.7 vs 84.1 mL/min/1.73m 2 , P > 0.05). Univariable and multivariable analyses did not show significant differences in postoperative eGFR between both groups among all‐comers, those with clamp times >30 min, and patients with baseline renal insufficiency. Risk of chronic kidney disease was not diminished by the off‐clamp approach with up to 5 years of follow‐up. Conclusions Progressive recovery of renal function after hilar clamping in the elective setting eclipses short‐term functional benefit achieved with off‐clamp LPN by 6 months; there was no significant difference in eGFR or the percentage incidence of chronic kidney disease between the on‐clamp and off‐clamp cohorts with up to 5 years follow‐up. As such, eliminating transient ischaemia during elective LPN does not confer clinical benefit.
