OBJECTIVE: The objective is to report the outcome of an anterior surgical approach to treat neuroma of the perineal branch of the pudendal nerve (PBPN). PATIENTS AND METHODS: An IRB-approved prospective study enrolled 14 consecutive male patients from 2011 through 2015 who had symptoms of perineal/scrotal pain. Each patient had a successful, diagnostic, pudendal nerve block. The surgical procedure was resection of the PBPN and implantation of the nerve into the obturator internus muscle...

PURPOSE: Previous studies in prostate cancer (PCa) patients tried to correlate the onset of local recurrence (LR) with the development of distant metastases and formulated, based on theoretical and experimental data, hypotheses linking the two events. We aimed to address this issue with 11 C-choline positron emission tomography/computed tomography (PET/CT). METHODS: This retrospective study included 491 PCa patients previously treated with radical prostatectomy who had undergone 11 C-choline PET/CT owing to biochemical failure...

Positive surgical margin (PSM) extension reported as focal or non-focal/extensive is an important pathologic prognostic parameter after radical prostatectomy. Likewise, there is limited or no agreement on how to measure and what the best cut-off points to be used in practice are. We hypothesized that digital microscopy (DM) would potentially provide a more objective way to measure PSM and better define its clinical significance. To further our knowledge, we have evaluated PSM status in 107 laparoscopic radical prostatectomies using digital and conventional light microscopy (LM)...

Zi Qin Ng, Richard Pemberton, Patrick Tan
Trocar site hernia is not a common acute complication encountered after robot-assisted surgery, especially in the urological cohort of patients. A few case reports of small bowel obstruction secondary to incarceration by trocar site hernia have been described in gynaecological surgery and prostatectomies. As the clinical presentation is non-specific, late diagnosis has significant implication on morbidity and mortality. Here, we present a rare case of a patient with recent robot-assisted laparoscopic partial nephrectomy for a renal cell carcinoma presented with features of impending bowel obstruction secondary to incarcerated small bowel in the trocar site...

This study aimed to investigate the prognostic value of a quantitative, detailed, yet practical analysis of perineural invasion in radical prostatectomy specimens in a high-risk prostate cancer cohort. A total of 114 patients with prostate cancer who underwent radical prostatectomy between 2000 and 2013 were analysed. Using S100 protein immunohistochemistry assisted in the detection of nerves. In the area of closest proximity of the tumour to the dorso-lateral margins, nerves were counted and the infiltration of nerves was categorised (0-3)...

Purpose Surgical performance is critical for clinical outcomes. We present a novel machine learning (ML) method of processing automated performance metrics (APMs) to evaluate surgical performance and predict clinical outcomes after robot-assisted radical prostatectomy (RARP). Methods We trained three ML algorithms utilizing APMs directly from robot system data (training material) and hospital length of stay (LOS; training label) (≤2 days and >2days) from 78 RARP cases, and selected the algorithm with the best performance...

OBJECTIVES: To evaluate the peri-operative, pathologic, and oncologic outcomes from surgeon led pathologic staging of pelvic lymph node metastases at the time of robot-assisted radical prostatectomy (RARP). PATIENTS AND METHODS: Over the 6-year period of 2006-2012, three distinct pelvic lymph node dissection strategies were utilized in chronologic order at a single cancer referral hospital. Strategies were characterized by both a 1) omission of PLND versus inclusion decision threshold, and 2) standard versus extended templates for patients selected for PLND...

Background and aims: To assess the outcomes of robotic radical prostatectomy in two different age subgroups of pre-operatively potent patients: younger than 50 years and older than 65 years. Methods: We included in the present study a number of 202 patients with prostate cancer divided into two groups: 99 patients older than 65 years (group 1) and 103 patients younger than 50 years (group 2). Results: More than half of the younger patients were low-risk vs 57% of the older patients who were high-risk...

Metastases to the pancreas account for less than 5 percent of all malignancies affecting the pancreas. The most common secondary malignancy of the pancreas is renal cell carcinoma. We report a patient presented with abdominal pain and weight loss. Computed tomography (CT) imaging showed pancreatic head mass. Biopsy from the mass showed prostate metastasis after 13 years from radical prostatectomy and Leuprolide therapy. This case demonstrates a rare location for prostate metastasis which was the pancreas. To our knowledge there are only six cases reported in literature...

BACKGROUND: Partin tables represent the most widely used predictive tool for prostate cancer stage at prostatectomy but with potential limitations. PURPOSE: To develop a new PartinMR model for organ-confined prostate cancer (OCPCA) by incorporating Partin table and mp-MRI with a support vector machine (SVM) analysis. STUDY TYPE: Retrospective. POPULATION: In all, 541 patients with biopsy-confirmed prostate cancer underwent mp-MRI...

Background: The objective in this paper was to validate the prognostic performance of the American Joint Committee on Cancer (AJCC) 7th and 8th systems among prostate cancer patients treated with radical prostatectomy. Methods: The surveillance, epidemiology and end results (SEER) database (2006-2014) was accessed through the SEER*Stat program and AJCC 7th and 8th editions were calculated utilizing T, N and M stages, histological grade group, as well as baseline prostatic-specific antigen (PSA)...

Radical treatments of prostate cancer often lead to a pervasive liminal state that is characterised by multiple uncertainties that relate both to a possible recurrence of cancer and recovery from side effects, such as erectile and urinary dysfunctions. Liminality can make it difficult for cancer patients to narrate their experiences, as their stories lack a definite ending. After interviews with 22 Finnish men who had undergone radical prostatectomy, we analysed how men produce closure in their illness narratives...

OBJECTIVE: To analyze factors associated with metastases, prostate cancer-specific mortality, and all-cause mortality in pN1 patients. MATERIALS AND METHODS: We analyzed 3,642 radical prostatectomy patients within the Shared Equal Access Regional Cancer Hospital (SEARCH) database. Pathologic Gleason grade, number of lymph nodes (LN) removed, and first postoperative prostate-specific antigen (PSA) (<0.2 ng/ml or ≥0.2 ng/ml) were among covariates assessed. Cox regression was used to analyze the association between characteristics and survival outcomes...

PURPOSE: To evaluate the variability induced by the imager in discriminating high-grade (Gleason≥7) prostate cancers (HGC) using dynamic contrast-enhanced MRI. MATERIAL AND METHODS: We retrospectively selected 3T MRIs with temporal resolution<10 seconds and comprising T1 mapping from a prospective radiologic-pathologic database of patients treated by prostatectomy. Ktrans, Kep, Ve and Vp were calculated for each lesion seen on MRI using the Weinmann arterial input function (AIF) and three patient-specific AIFs measured in the right and left iliac arteries in pixels in the center of the lumen (psAIF-ST) or manually selected by two independent readers (psAIF-R1 and psAIF-R2)...

PURPOSE: Pelvic lymph node dissection (PLND) is recommended for patients with prostate cancer (PCa) and significant risk for nodal metastases. This study aimed to assess guideline adherence regarding PLND according to the German S3 guideline as example for a national but highly used guideline on prostate cancer and to compare the rate of complications different approaches for radical prostatectomy (RP). METHODS: Patients undergoing open (RRP), laparoscopic (LARP) or robot-assisted (RARP) RP in six centers in Germany and Austria were included...
