Pudendal nerve branch injury during radical perineal prostatectomy

2005

We report the first case of direct surgical injury to a pudendal nerve branch during radical perineal prostatectomy. A 65-year-old patient presented with typical symptoms of a pudendal nerve lesion after radical perineal prostatectomy. As the patient did not respond to conservative treatment, surgical exploration and exeresis of the injured sensory branch of the pudendal nerve was necessary, resulting in pain improvement. Urologic surgeons should be aware of the typical symptoms after iatrogenic injury to the pudendal nerve or its branches. Early diagnosis and neurosurgical intervention are important to obtain a more favorable outcome.

A curved Lowsley retractor improves manoeuvrability of the prostate during ascending radical retropubic prostatectomy

2007

Worldwide, radical retropubic prostatectomy is the commonest surgical procedure for treating localized prostate cancer. The technique has evolved continuously over the years, yielding improved continence and potency while reducing considerably the associated complications. Simple surgical ‘tricks’ have been proposed for crucial steps, e.g. the control of the dorsal venous complex, atraumatic dissection of the neurovascular bundles (NVBs), improved visualization of the urethral stump and tailoring of the vesicourethral anastomosis [1,2].

Presence of atrial natriuretic factor in normal and hyperplastic human prostate and its relationship with oxytocin localisation

2003

In this work, we showed the presence of atrial natriuretic factor (ANF) in human prostate and compared its localisation in normal and hyperplastic conditions. ANF was localised in epithelial and stromal cells, being increased in hyperplasia, mainly in the stromal component. Moreover, we compared ANF and oxytocin positivity in the same glands, focusing on the possible relationship between the paracrine effects of these two hormones.

Chronic Prostatitis and Prostatodynia: Ultrasonographic Alterations of the Prostate, Bladder Neck, Seminal Vesicles and Periprostatic Venous Plexus

1988

Transrectal ultrasonography was performed in 121 patients with the chronic prostatitis syndrome (CPS), and in 20 patients with urological pathology not involving the prostate gland. The ultrasonographic aspects of the seminal vesicles (SV) in normal subjects and in patients with the CPS are described. In the latter group, characteristic ultrasonographic patterns can often be obtained, even in patients affected by prostatodynia, in whom all the other clinical and laboratory findings were absent. They consisted of: (a) dyshomogeneous echo-structure of the prostate; (b) constant dilatation of the periprostatic venous plexus, greater than 150 mm2; (c) dilated, elongated SV, with thickening of t…

Interactive computerized morphometric analysis for the differential diagnosis between dysplasia and well differentiated adenocarcinoma of the prostate

1989

To distinguish prostatic dysplasia (or adenosis) from well differentiated adenocarcinoma on transrectal needle biopsy, a morphometric study was conducted on 20 cases of adenosis and 20 cases of well differentiated adenocarcinoma of the prostate. About 100 cells for each patient were analyzed by means of a computerized image analyzer, and mean nuclear diameter, mean nuclear area, mean form factor and number of cells in eight classes of nuclear diameter were studied. The best predictors of malignancy (evaluated by means of Receiver Operating Characteristics curves) were mean nuclear area greater than 28 mu2, presence of more than 5% of cells with nuclear diameter greater than 6.15 mu, and mea…

Relationship between PTH and PSA Values in Patients with Pathological Finding of Benign Prostatic Hyperplasia

2012

The functional relationship between parathyroid glands and prostatic gland is commonly very well known. The aim of our study was to investigate the relationship between serum levels of PTH and serum levels of PSA in patients with pathological finding of BPH. According to 261 transrectal ultrasound-guided prostatic biopsies performed from March 2009 to March 2010, 75 patients, responding to our inclusion criteria, were selected. 26 patients (34.6%) ended the study. All patients with high serum levels of PSA (>4 ng/mL), with histological diagnosis of benign prostatic hyperplasia, underwent the assay of serum levels of PTH. We observed high levels of PTH (> 66 pg/mL) in 9 patients (35.2…

Immunohistochemical evaluation of PCNA, p53, HSP60, HSP10 and MUC-2 presence and expression in prostate carcinogenesis

2003

Background: The study of the expression of different biological markers in non-neoplastic, pre-neoplastic and neoplastic lesions of prostate could help to better understand their role in carcinogenesis and to find new diagnostic and prognostic tools. Materials and Methods: In the present work we evaluated, by immunohistochemistry, the presence and the expression of PCNA, p53, HSP60, HSP10 and MUC-2 in a series of nodular hyperplasia, low- and high-grade prostatic intraepithelial lesions and adenocarcinomas. Results: Our data confirmed that: 1) PCNA expression could be related to the grade of progression of cancer; and that 2) p53 mutation could be a late event in prostate carcinogenesis. Mo…

Clinical intervals and diagnostic characteristics in a cohort of prostate cancer patients in Spain: a multicentre observational study

2015

BACKGROUND: Little is known about the healthcare process for patients with prostate cancer, mainly because hospital-based data are not routinely published. The main objective of this study was to determine the clinical characteristics of prostate cancer patients, the, diagnostic process and the factors that might influence intervals from consultation to diagnosis and from diagnosis to treatment. METHODS: We conducted a multicentre, cohort study in seven hospitals in Spain. Patients' characteristics and diagnostic and therapeutic variables were obtained from hospital records and patients' structured interviews from October 2010 to September 2011. We used a multilevel logistic regression mode…

Salvage reirradiation for locoregional failure after radiation therapy for prostate cancer: Who, when, where and how?

2014

Even in the current era of dose-escalated radiotherapy for prostate cancer, biochemical recurrence is not uncommon. Furthermore, biochemical failure is not specific to the site of recurrence. One of the major challenges in the management of prostate cancer patients with biochemical failure after radiotherapy is the early discrimination between those with locoregional recurrence only and those with metastatic disease. While the latter are generally considered incurable, patients with locoregional disease may benefit from emerging treatment options. Ultimately, the objective of salvage therapy is to control disease while ensuring minimal collateral damage, thereby optimizing both cancer and t…
