PURPOSE: Our objective is to determine the accuracy of multiparametric MRI (mpMRI) in predicting pathologic grade of prostate cancer (PCa) after radical prostatectomy (RP) using simple apparent diffusion coefficient metrics and, specifically, whether mpMRI can accurately separate disease into one of two risk categories (low vs. higher grade) or one of three risk categories (low, intermediate, or high grade) corresponding to the new prognostic grade group (PGG) criteria. METHODS: This retrospective, HIPAA-compliant, IRB-approved study included 140 patients with PCa who underwent 3 T mpMRI with endorectal coil and transrectal ultrasound-guided (TRUS-G) biopsy before RP...

PURPOSE: To assess the diagnostic weight of sequence-specific magnetic resonance features in characterizing clinically significant prostate cancers (csPCa). MATERIALS AND METHODS: We used a prospective database of 262 patients who underwent T2-weighted, diffusion-weighted, and dynamic contrast-enhanced (DCE) imaging before prostatectomy. For each lesion, two independent readers (R1, R2) prospectively defined nine features: shape, volume (V_Max), signal abnormality on each pulse sequence, number of pulse sequences with a marked (S_Max) and non-visible (S_Min) abnormality, likelihood of extracapsular extension (ECE) and PSA density (dPSA)...

Dose painting by numbers (DPBN) refers to a voxel-wise prescription of radiation dose modelled from functional image characteristics, in contrast to dose painting by contours which requires delineations to define the target for dose escalation. The direct relation between functional imaging characteristics and DPBN implies that random variations in images may propagate into the dose distribution. The stability of MR-only prostate cancer treatment planning based on DPBN with respect to these variations is as yet unknown...

PURPOSE: To illustrate whether De Ritis (aspartate transaminase-AST/alanine transaminase-ALT) ratio is useful in risk stratification of localized prostate cancer and propose an easy predictive model for biochemical recurrence-free survival (BCRFS). METHODS: In total, 438 patients who underwent radical prostatectomy were included in this study. Blood samples including AST and ALT were collected 1-7 days before surgery. An elevated AST and ALT value was defined as over 40 or 56 IU/L...

BACKGROUND: The Cancer of the Prostate Risk Assessment Post-Surgical (CAPRA-S) score is a simple post-operative risk assessment tool predicting disease recurrence after radical prostatectomy, which is easily calculated using available clinical data. To be widely useful, risk tools require multiple external validations. We aimed to validate the CAPRA-S score in an Australian multi-institutional population, including private and public settings and reflecting community practice. METHODS: The study population were all men on the South Australian Prostate Cancer Clinical Outcomes Collaborative Database with localized prostate cancer diagnosed during 1998-2013, who underwent radical prostatectomy without adjuvant therapy (n = 1664)...

We present preliminary results of a case series on refractory bladder neck contracture (BNC) treated with robot-assisted laparoscopic Y-V plasty (RAYV). Between 01/2013 and 02/2016, 12 consecutive adult male patients underwent RAYV in our hospital. BNC developed after transurethral procedures (n = 9), simple prostatectomy (n = 2) and HIFU therapy of the prostate (n = 1). Each patient had had multiple unsuccessful previous endoscopic treatments. All RAYV procedures were performed using a transperitoneal six-port approach (four-arm robotic setting)...

INTRODUCTION: Endoscopic extraperitoneal radical prostatectomy (EERPE) has gained popularity for the treatment of localized prostate cancer. However, prior complex lower abdominal or pelvic surgery can complicate subsequent EERPE. To date, there have been few reports on patients who underwent EERPE after radical resection of pT1-pT2 rectal cancer. AIM: To present our experience with EERPE in patients after radical resection of pT1-pT2 rectal carcinoma and introduce a simple and effective way to create an extraperitoneal working space...

Inguinal herniation of a bladder diverticulum is a rare finding. The diagnosis should be suspected if the size of hernia is variable on urination. These patients may also experience obstructive voiding symptoms. Various imaging modalities may clarify the diagnosis. In our patient, intravenous urography precisely showed a bladder diverticulum in the right inguinal area. The patient underwent open simple prostatectomy and herniorrhaphy. He remains symptom-free on follow-up.

REVIEW
Ross Cockrell, David I Lee
PURPOSE OF REVIEW: The leading cause of voiding dysfunction in older men is benign prostatic obstruction. In the setting of a grossly enlarged prostate (>80cm(3)), an open simple prostatectomy has been the gold standard for surgical treatment. Here, we will discuss the minimally invasive robot-assisted approach and compare it to the classic open approach and holmium laser enucleation of the prostate. RECENT FINDINGS: Literature on robot-assisted simple prostatectomy, in concurrence with our institutional experience, has shown an overall lower morbidity, shorter hospital stay, and decreased indwelling catheter time, with equivalent functional outcomes compared to open simple prostatectomy...

To prevent inguinal hernia after retropubic radical prostatectomy, many urologists have utilized a prevention technique of inguinal hernia at the same time as retropubic radical prostatectomy. Here, we report the clinical benefit of the prevention technique of inguinal hernia as well as risk factors for the incidence of inguinal hernia. We investigated the medical records of 223 men who underwent retropubic radical prostatectomy for clinically localized prostate cancer between January 2007 and March 2013 at our medical center...

BACKGROUND: Presence of small (tertiary) Gleason 5 pattern is linked to a higher risk of biochemical recurrence in prostate cancer. It is unclear, however, how to integrate small Gleason 5 elements into clinically relevant Gleason grade groups. OBJECTIVE: To analyze the prognostic impact of Gleason 5 patterns in prostate cancer and to develop a method for integrating tertiary Gleason 5 patterns into a quantitative Gleason grading system. DESIGN, SETTING, AND PARTICIPANTS: Prostatectomy specimens from 13 261 consecutive patients and of 3295 matched preoperative biopsies were available...

Operative management of prostate cancer in a patient who has undergone previous open suprapubic simple prostatectomy poses a unique surgical challenge. Herein, we describe a case of intermediate risk prostate cancer in a man who had undergone simple prostatectomy ten years prior to presentation. The patient was found to have Gleason 7 prostate cancer on MRI fusion biopsy of the prostate for elevated PSA and underwent an uncomplicated robot assisted laparoscopic radical prostatectomy.
