Male sexual dysfunction in patients with chronic end-stage renal insufficiency and in renal transplant recipients.

MATERIALS AND METHODS: The study was conducted from December 2011 to December 2012 on 95 patients between the ages of 20 and 65 years: 44 of which had been undergoing dialysis for over a year and 51 of whom had undergone kidney transplants more than 6 months before. Comorbidities were carefully recorded, erectile function was evaluated the with IIEF5 questionnaire and serum levels of total testosterone / free and prolactin were tested at early morning (7 AM). To assess the relationship between erectile dysfunction (ED) and clinical laboratory tests, Student's t-test statistical (quantitative variables), chi-square (qualitative variables), the uni and multivariate analysis were used. RESULTS: In patients undergoing dialysis and in recently transplanted patients a higher instance of ED was found (70% and 65% of cases respectively). Amongst dialyzed patients, patients aged over 50 suffer from ED more frequently. Patients aged over 50s represent 61% of the total number of patients suffering from ED, and just 31% of patients not suffering from ED, (p = 0.006); Hyperprolactinemia was found in 23% and 20% of both groups respectively. Fifty nine % of the dialyzed patients presented values of testosterone serum levels of less than 250 ng/dl with a significant difference between those who were suffering from ED and those who were not (65% of ED patients vs. 46%,of patients not affected from ED p = 0.019). This was found in only 37% of transplanted patients and there does not appear to be a statistically significant correlation with the onset of ED (p = 0.12). In patients over the age of 50, diabetes and a condition of hypotestosteronemia were significantly correlated with ED at univariate and multivariate analyses. CONCLUSIONS: The ED in patients with end stage chronic kidney failure (CKF) continues to have a strong prevalence, either in the patients who are undergoing dialysis or in those who have received transplants. In literature this issue is not sufficiently considered if not at all. Hypotestosteronemia is a risk factor for the onset of ED in end stage CKF patients. A significantly lower prevalence of hypogonadism among dialyzed patents and transplant recipients suggests that renal transplantation may be protective for the sexual capabilities of these patients.

The role of alternative medicine and complimentary therapies in urologic disease: New horizons.

The world of complementary and alternative medicine (CAM) encompasses a wide range of practices, treatments, and products that fall outside the realm of conventional (mainstream) medicine. The use of complementary and CAM has become increasingly popular in Western nations. People are turning to CAM for a variety of reasons, including managing chronic diseases, relieving symptoms of various conditions, and improving their overall health and well-being. There's a growing trend of people using and showing interest in complementary and alternative medicine therapies, especially in Western countries. CAM encompasses a wide range of treatments, some offering complete alternatives to conventional medicine, while others aim to complement existing medical approaches. Urologists should stay informed about CAM to guide their patients effectively to treat patients in a modern and personalized way. The aim of review is to analyze the scenario of complimentary and alternative medicine with a specific focus in the urological field.

[Surgery for male urinary incontinence: where are we now and what is in the pipeline?]. / Chirurgia dell'incontinenza urinaria maschile: a che punto siamo?

Male stress urinary incontinence, which has radical prostatectomy as the main aetiology, affects about 39% of the adult male population and is one of the complications of radical prostatectomy with the greatest impact on the quality of life of patients. There are a wide range of treatments for stress urinary incontinence available to the urologist, ranging from conservative treatments to surgical treatments, from minimally invasive procedures to the implant of artificial sphincter prosthesis. The aim of this work is to define the state-of-the-art of surgical treatments for male stress urinary incontinence, analyzing the most recent studies in the literature and evaluating the available scientific evidence.

[Antibiotic prophylaxis in urology]. / La profilassi antibiotica in Urologia.

INTRODUCTION: Antibiotic prophylaxis (AP) is used to minimize infectious complications resulting from interventions. Due to high rates of development of bacterial resistance and side effects, the use of antibiotics must be weighed on the basis of high levels of evidence. The main endpoints of urology AP are the prevention of symptomatic urogenital infections, urosepsis and wound infections. The purpose of this review is to bring objectives, principles and recommendations on urology AP according to the latest scientific evidence. METHODS: We carried out a systematic search of MEDLINE, EMBASE and the Cochrane Library using keywords such as AP, prophylaxis, antibiotics, urological surgery, urogenital surgery and the names of the urologic procedures. The results of studies on the AP for each procedure were classified according to the levels of evidence and grades of recommendation from the European Association of Urology. RESULTS: There are a number of good quality studies on AP about endoscopic resection of the prostate (TURP), urodynamic studies and transrectal prostate biopsies (trPB). The majority of the studies about other procedures have several limitations (sample size, consistency of definitions, statistics and trial design). Lack of consistency in the definitions of infectious complications does not allow comparison between different studies. CONCLUSIONS: The AP is evidence-based is indicated only for TURP and trPB. It is desirable to perform randomized, prospective and controlled trials in order to rationalize the use of antibiotics, improve the cost/benefit ratio and reduce bacterial antibiotic resistances.

[Positive surgical margins in nephron sparing surgery for renal cell carcinoma]. / Margini chirurgici positivi nella chirurgia conservativa del carcinoma renale

Nephron sparing surgery (NSS) with a minimal tumor-free margin is considered the cornerstone in the contemporary management of renal cell carcinoma (RCC) stage T1. The aim of this study is to review incidence, predictive risk factors, clinical significance and oncologic outcomes of positive surgical margins (PSM) in NSS. English articles published before March 2014 have been searched in Medline Databank.PSM are present in 0-7% of patients in all surgical approaches considered. Some predictive factors,such as tumor size, localization, and histology have been identified in the past. Other topics concerning surgical technique and approach are discussed.The majority of patients with PSM do not experience disease recurrence and PSM impact on overall survival and cancer-specific survival seems to be irrelevant. These results lead to more conservative clinical strategies. However, an active surveillance is mandatory for all patients with PSM and especially for those with high risk disease. Generalization of these results is limited by the low level of evidence of available studies. Further efforts are necessary to avoid PSM intraoperatively and to provide prospective information in order to standardize the postoperative management.

[Brachytherapy in men with prostate cancer: update on indications and outcomes]. / Brachiterapia nel trattamento del carcinoma prostatico: indicazioni ed efficacia.

Brachytherapy (BT), using either a low-dose-rate (LDR) or mostly high-dose-rate (HDR) technique, is the device able to deliver the highest dose-rate in the most conformal way. It is used as monotherapy or in combination with external beam radiotherapy (EBRT). LDR-BT is mostly used as monotherapy; HDR-BT is combined with EBRT ± adjuvant hormone therapy. In patients with low-risk disease and in selected intermediate-risk patients, LDR-BT ensures long-term good disease control rates and HDR-BT can show similar results, even if with shorter follow-up. In patients with intermediate/high risk disease the combination therapy (EBRT + HDR-BT) shows better oncological outcomes compared to EBRT monotherapy, even if the role of adjuvant hormone therapy is still unclear. Literature shows variable efficacy of BT in case of local recurrence after EBRT and radical prostatectomy even if few cases have been reported with short follow-up. Side effects are acceptable (urogenital toxicity, urinary incontinence, sexual function) and comparable with the other treatment modalities. So far, randomized controlled trials comparing the different treatment modalities are necessary to clarify indications and real efficacy.

[Focal surgery in testis cancer: current state of the art]. / Chirurgia focale per il tumore del testicolo: stato dell'arte.

Radical orchiectomy is the standard treatment of testicular neoplasia causing androgen insufficiency, infertility and psychological stress. Focal surgery allows the preservation of fertility, endocrine function and integrity of the genital anatomy, with preservation of the image of the male body. The EAU guidelines suggest focal surgery in case of synchronous bilateral tumors, metachronous contralateral tumours, tumour in solitary testis with normal pre-operative testosterone levels, when the tumor volume less than 30% of the testicular volume. There are two focal surgical techniques: tumorectomy and polar resection, followed by biopsies and frozen section of the resection bed. In case of benign tumours, the treatment is often curative. In case of malignancy, carcinoma in situ is frequently found in the surrounding tissues. Adjuvant treatment with chemotherapy or radiotherapy is performed with a fair success rate. These adjuvant treatments reduce or delete the functional benefits achieved by conservative surgery. The evidence of the literature suggests that focal surgery is a valid option for all patients with testicular tumours that are not palpable and small sized, with the advantage of avoiding unnecessary radical orchiectomy in most cases. Therefore, the selection criteria for focal surgery are the mass size (less than 25 mm) and a safety distance of the tumor from the rete testis, in order to preserve testicular vascularization. A close follow-up with ultrasound, testicular markers and radiological examinations is mandatory in case of germ cell neoplasia treated conservatively in patients with indications for conservative surgery.
