Abstract Background Nowadays, the histological examination of prostate core needle biopsies is still regarded as the gold standard in the diagnosis of prostate cancer (PCa). We investigated if the tissue print of core needle biopsy (biopsy print) could be used as adjunctive molecular investigative procedures in conjunction with routine histological examination of biopsy to improve PCa diagnosis. Methods The direct contact of PCa core biopsy to nitrocellulose membrane resulted in the release of a cellular micropeel that was used for downstream analytical procedures. Results By zymogram print-phoresis we demonstrated that matrix metalloproteases MMP-2 and MMP-9 could be visualized in biopsy prints and that the gelatinolytic activity was positively correlated with immunohistochemistry analysis of the same markers in matched bioptic specimens. Moreover, we compared the ability to detect the PCa-associated hypermethylation of GSTP1 promoter in DNA extracted from biopsy prints with those of the corresponding core needle biopsies. Biopsy prints demonstrated the same specificity of biopsies in detecting PCa (50%) while the sensitivity and the positive predictive value were lower than biopsies (56% vs 78% and 63% vs 70%, respectively). Conclusions Biopsy print, combining a molecular point of view to the routinely hystopathological analysis of prostate biopsies, should be a useful tool to improve the diagnosis of PCa.

Abstract Background 30 patients, with T1 renal cell carcinomas (RCC) who underwent open enucleoresection of the tumour, were randomized to the use of a topical haemostatic agent (Floseal) or to an infrared-sapphire coagulator (ISC), to compare their efficacy in achieving haemostasis. Methods: Successful intra-operative haemostasis, intra- and post-operative bleeding, operative time, hospital discharge were evaluated. Results Statistically higher rates of successful haemostasis and shorter time-to-haemostasis (8,1 vs 12,9 min) were observed in the FloSeal group (p < 0.001 both). Patients operative time was not different between Group 1 vs 2 (58.7 ± 12 vs 62.4 ± 15; p > 0.05). The average blood loss during surgery was less (60 +/- 25.5 mL) for the FloSeal group than for the ISC group (85 +/- 40.5 mL) (p < 0.05). Postoperative blood loss was 25 +/- 5 mL and 40 +/- 45 mL for Floseal and ISC respectively, (p < 0.05). Length of the postoperative hospital discharge was 2.5 +/- 1.2 days for FloSeal group and 3.5 +/- 1.3 for the Group 2 (p < 0.05). No major immediate or delayed complications were observed in either Groups. Conclusions The use of Floseal and ISC offer a safe and efficacy haemostasis in the enucleoresection of RCC. Moreover, our results show a less intra-operative and post-operative blood loss as well as a shorter time to haemostasis of Floseal in respect to ISC.

OBJECTIVES: Nephron sparing surgery (NSS) is now considered the standard of care in the treatment of renal cell carcinoma (RCC) in stage T1. We retrospectively evaluated our results related to the use of NSS in over twenty years of clinical practice. METHOODS: We reviewed our database relating to the use of NSS in the last twenty years of clinical practice, from 1988 to July 2012, in 549 patients. The pre- and post-operative parameters recorded are the evaluation of the site and size of the renal lesion obtained from radiological investigations, the need for clamping the renal pedicle, open or laparoscopic surgical approach, blood loss, histology and intra- and postoperative complications. We also evaluated the parameters related to renal function before and after surgery. RESULTS: The mean follow-up was 95 months (7.6 years). The average diameter of the lesion at CT abdomen was 4.8 cm (1-8 cm). The warm ischemia was required in 317 patients, cold in 18 patients, no need for ischemia in 214 patients. The total duration of surgery was 122.56 ± 52.76 min. 15 procedures were performed laparoscopically. Ischemia time: 3'-25'; bleeding: 50-1000 cc. The lesion was benign in 115 of the 549 patients enrolled; it was a RCC in the remaining cases except for three, which were papillary carcinomas. At 5 years, the cancer free survival rate was 97.5%. CONCLUSIONS: Our data show that the implementation of NSS offers long-term benefits in terms of functional results and a good cancer control. [ABSTRACT FROM AUTHOR]

OBJECTIVE: The aim of our study has been to evaluate our results in the treatment of urethral stenosis through several surgical approaches of urethroplasty: the one-stage procedure by direct end-to-end anastomosis, the free dorsal onlay graft urethroplasty using buccal mucosa, and the two-stage urethroplasty. METHODS: Between February 2009 and January 2012, 53patients were enrolled and analyzed for different types of urethral reconstruction. RESULTS: The procedures included direct end-to-end anastomosis in 26 patients (49%), 18 (34%) underwent a two-stage urethroplasty (Johansen's), in 9 a free dorsal onlay buccal mucosa urethroplasty was performed. At a mean follow-up of 17 months, we had an overall success rate of 95%. When stratified on the basis of the procedure performed, in the direct end-to-end anastomosis 98% of patients had no evidence of recurrent stricture, 96% of success rate was reached in the onlay buccal mucosa urethroplasty, and 91% in the two-stage procedure. CONCLUSIONS: In patients with urethral strictures, urethroplasty has to be preferred with respect to urethrotomy, which is the cause of a high percentage of recurrence, and holds the risk of compromising the success of further surgical procedures of urethroplasty. Differently, several techniques of urethroplasty offer a high percentage of success rate until 95%, as showed by our results. [ABSTRACT FROM AUTHOR]

We performed a randomized, prospective, controlled, intention to treat study in order to determine the effectiveness of an antioxidant therapy in improve the quality of seminal fluid parameters and the natural pregnancies in men with persistent oligospermia (5–20 million/ml) 6 months after retrograde embolization. Forty-two subjects were enrolled and randomized in the study. Treated group (20 subjects) was assigned to receive antioxidant therapy (NAC 600 mg and vitamins–minerals). Untreated group (22 subjects) received no adjunctive medical therapy and was used as controls. Our data were analyzed with an intention to treat strategy. A statistically significant increase in sperm count after antioxidant therapy was recorded ( P = 0.009). After this therapy, no statistical differences in percentage of WHO class A motile sperm ( P = 0.752) and typical forms ( P = 0.926) were found. The univariate logistic regression analysis showed that a man treated with antioxidant therapy presented a probability to have a normal sperm count 20-fold (OR = 20.1; CI 95% = 1.05–43.2; P = 0.014) higher than a man who was untreated. No significant impact on spontaneous pregnancies was found after antioxidant therapy. Despite this preliminary data, we show that antioxidant therapy based on a combination of NAC and micronutrient supplementation can be helpful in improve the sperm count at least in a subset of oligospermic males. However, this improving in sperm count is not associated with a significant increase in spontaneous pregnancies after 12 months. [ABSTRACT FROM AUTHOR]

INTRODUCTION. Overactive Bladder (OAB) and Urge Urinary Incontinence (UUI) are both debilitating and bothersome conditions. OAB negatively impact on women's quality of life affecting their own ability and personal relationships. Our aim has been to evaluate how OAB and UUI affect women's sexual function and the possible role of antimuscarinic drugs in improving their sexual condition. MATERIALS AND METHODS. From January 2009 to May 2010, 58 women diagnosed with OAB filled in the self-administered questionnaires: Female Sexual Function Index (FSFI), the short form of Urogenital Distress Inventory (UDI-6) and the Incontinence Impact Questionnaire (IIQ-7). 33 of them (57%) reported a FSFI score<26,55 and were treated with Solifenacin 5mg. they were re-evaluated with the same questionnaires after three months of therapy. RESULTS. The mean FSFI score of 33 patients affected by Female Sexual Disfunction (FSD) was 21,8 (range: 18,6-25,7). The six domains designed to address different aspects of female sexual dysfunctions, sexual desire, satisfaction, orgasm, arousal, lubrication and related pain symptoms, were altered in 48, 33, 21, 15, 12 and 8% of the patients respectively. In 70% of the patients, FSFI score improved of a mean of 5,4 after three months of therapy; UDI-6 and IIQ-7 decreased from 56,3 and 59,9 to 47,6 and 50,2, respectively. Considering women with UUI + OAB or OAB alone, we reported a significant improvement of urinary symptoms and women sexual condition after three months of therapy. CONCLUSION. OAB syndrome was found to cause greater deterioration in women sexual function. Antimuscarinic drugs are the mainstay of pharmacologic treatment of OAB able to improve urinary symptoms, enhance quality of life and female sexual condition. [ABSTRACT FROM AUTHOR]

Introduction: Overactive bladder syndrome (OAB) is a chronic disease, the prevalence in the general population is reported to be 14-16%. Anti-muscarinic agents are considered the first-line pharmacological treatment for the management of OAB; although a long lasting therapy is indicated to reach a better control of OAB symptoms an high percentage of patients discontinue the cure after a brief period. Our attempt is to investigate whether the cost of solifenacin succinate may influence the long lasting regimen and patients' drug efficacy., Materials and Methods: 70 consecutive women, with symptoms of OAB were enrolled in this randomized controlled study. In group A, all patients received solifenacin 5 mg by the urologist, without any cost; they were instructed to get the drug once daily for 4 months, differently, in group B, patients need to buy the drug which was administered as in the group A. Frequency, nocturia, incontinence, voided volume, were evaluated by a 3-day micturition diary. Overactive Bladder Questionnaire Short Form (OAB-qSF) was used to assess the impact of OAB symptoms on patients' quality of life (QoL). Urgency was assessed by patient's perception of intensity of urgency scale (PPIUS). Micturition-diary, OAB-qSF, PPIUS, were completed at baseline and after four months., Results: A greater number of patients discontinued solifenacin in the group B who need to buy the drug. We observed significant differences in groups A and B in relation to frequency, nocturia, urge incontinence and voided volume comparing the pre and post treatment symptoms. The patients' perceptions of intensity of urgency and the PGI-I scale showed a significant improvement greater in group A in respect with group B., Conclusions: The cost of anticholinergic may be responsible for both early discontinuation of treatment and incomplete adherence to therapy with unsatisfactory results on symptoms and an incorrect assessment of the effectiveness of the drug by the urologist.

It is known that serum prostate-specific antigen levels (PSA) decrease gradually following surgery for benign prostatic hyperplasia (BPH), but there is not an established cut-off value for normal PSA after relief of obstruction. We evaluated the impact of prostatic adenoma enucleation on PSA levels in 110 patients who underwent transvesical suprapubic adenomectomy for symptomatic BPH. We examined PSA levels before and after open surgery and weight of the prostatic adenoma as measured by the pathologist. Forty-eight percent of the patients had a preoperative PSA level between 0 and 4, 29% between 4 and 7, and 23% between 7 and 10 ng/ml. In patients with suspected abnormality on digital rectal examination or PSA > 4.0 ng/mL systematic multisite biopsies were performed preoperatively to rule out prostate cancer. The mean weight of enucleated adenoma was 87 gr (range 50-201). The mean serum PSA decreased from 4.8 ng/ml preoperatively to 0.5 ng/ml postoperatively. The mean decrease in PSA was 90% (range 70-99%). PSA was resetted at lower level in all patients irrespectively of baseline PSA levels or BPH weight. The transvesical suprapubic adenomectomy supernormalises serum PSA lower than 1 ng/ml in 96% of patients. 100% of patients have a postoperative PSA value < 1.5 ng/ml. PSA supernormalisation represents an objective measure of complete adenoma removal. The urologists should be aware of this resetted level and they should take account of it when different ablative therapies for BPH are confronted.

Objectives: Prostate sarcomas are rare entity, the most common is leiomyosarcoma which account for 0.1% of all prostate malignancies. The presenting symptoms are mainly obstructive urinary symptoms. Surgery with chemo- or radiotherapy are the mainstay treatment options. The overall survival rate remains poor regardless of initial tumour size, grade or histological subtype. Immunohistochemistry reveals tumour cells diffusely positive for vimentin, smooth muscle actin, focally positive for progesterone receptor, whilst keratins are usually negative., Materials and Methods: We describe a case of a patient affected by sarcoma of prostate. Furthermore, we reviewed the cases of prostate sarcomas available in literature to clarify the best therapeutic options to be applied., Results: In the case described leiomyosarcoma diagnosed by an ultrasound guided biopsy was characterized by fascicles of spindle-shaped cells with a variable degree of nuclear atypia. The immunohistochemistry showed positive staining for smooth muscle actin, vimentin and focally for the S-100 protein. The patient was treated with radical retropubic prostatectomy and radiotherapy of the local recurrence, and chemotherapy at metastases onset., Conclusions: Prostate sarcomas are highly aggressive, with limited therapeutic options. An early diagnosis and complete surgical excision with negative margins offer patients the long-term disease free survival.

The objective of the present study was to evaluate the efficacy of the periprostatic nerve block (PNB) of the prostate-vesicular junction with low volume and high concentration of anesthetics in relieving pain during prostate biopsy. Two hundred and twenty patients were enrolled and randomized to receive PNB with 5 ml 2% lidocaine (group 1110 pts) and PNB with 5 ml 2% mepivacaine (group 2, 110 pts). The anesthetic was administered through a single puncture on each side at the prostate-vesicular junction using a 22-gauge needle. All patients filled in a ten visual analogue pain score scale (VAS) from 0 = no discomfort to 10 = severe pain, for the assessment of pain experienced during biopsy. The two groups were homogeneous concerning the anthropometrical data. The mean pain score with lidocaine was 1.4 +/- 1.02 (CI 95% = 1.53 to 3.57) and with mepivacaine was 1.3 +/- 1.06 (CI 95% = 2.66 +/- 4.84) with no statistical significant difference between groups (p = 0.43). No general or local adverse effects were observed between the anaesthetics. The use of a low volume (2.5 ml on each side) and high concentration (2%) of local anesthetics (lidocaine/mepivacaine) almost completely suppresses pain and discomfort associated with prostate biopsy. The anatomy of neurovascular bundle regions appears favourable to the administration of small amounts of anesthetic.
