RESUMO
PURPOSE: The management of mildly elevated (4.0-10.0 ng/ml) prostate specific antigen (PSA) is uncertain. Immediate prostate biopsy, antibiotic treatment, or monitoring PSA level for 1-3 months is still in controversy. MATERIALS AND METHODS: We retrospectively analysed the effect of empiric antibiotics on an increased PSA in a mono-institutional study. We analysed the data of 100 patients with a PSA of 4-10 ng/ml and normal digital rectal examination undergoing their first prostate biopsy. Patients were divided in two different cohorts. One cohort was submitted to antibiotic therapy (Levoxacin 500 mg daily for 20 days) and both cohort had a re-dosing of PSA before the prostate biopsy. RESULTS: Average age of the whole group of patients was 66.48 ± 8.32 years and their average initial PSA level was 6.67 ± 1.57 ng/mL. In the treated group (N = 49) 29 patients had a decreasing PSA value from mean baseline PSA value of 6.6 ± 1.54 ng/ml to the re-dosed mean PSA level of 5.4 ± 1,61 ng/ml (p = 0.7); 20 patients didn't experience a decrease PSA value, with a mean PSA level of 6.9 ± 1.68 ng/ml. In the control group (N = 51), 30 patients had a decrease of PSA level from mean baseline PSA level of 6.5 ± 1,59 ng/ml to a re-dosed PSA level of 5.5 ± 1.57 ng/ml; 21 patients didn't experience a decrease of PSA value, with a mean PSA level of 6.7 ± 1.71 ng/ml. Multivariate analysis of age, PSA changes, antibiotics therapy and biopsy results (presence or absence of cancer) revealed no significant difference between the two cohorts. Sepsis after biopsy occurred in 3 patient in the antibiotics group (6%) and in one of the control group (2%). CONCLUSIONS: The study, even with some limitations, does not seem to show an advantage due to the administration of antibacterial therapy to reduce PSA values before prostate biopsy and subsequently to reduce unnecessary prostate biopsies.
RESUMO
OBJECTIVES: To determine whether there are differences in sperm parameters improvement after different varicocele correction techniques. To determine the role of age in sperm parameters improvement. METHODS: 2 different European centers collected pre- and postoperative sperm parameters of patients undergoing varicocele correction. Among 463 evaluated patients, 367 were included. Patients were divided in procedure-related and age-related groups. Ivanissevich inguinal open surgical procedure (OS), lymphatic-sparing laparoscopic approach (LSL) and retrograde percutaneous transfemoral sclerotization (RPS) were performed. As outcome measurements sperm count (millions/mL, SC) and percentage of mobile sperms were analyzed. Univariate and multivariate regression between the defined groups; bivariate regression analysis between age and sperm count and motility. RESULTS: Number of patients: OS 78; LSL 85; RPS 204. Mean age 30.2 (SD 6.83); postoperative SC increased from 18.2 to 30.1 (CI 95% 27.3-32.9; p < 0,001); motility from 25.6 to 32.56% (30.9-34.2; p < 0.001). OS: SC varied from 16.9 to 18.2 (p < 0.001); sperm motility from 29% to 33% (p < 0.001). LSL: SC from 15.5 to 17.2 (p < 0.001); motility from 27 to 31% (p < 0.001). RPS: SC from 18.9 to 36.2 (p < 0.001); motility from 24% to 32% (p < 0.001). Univariate and multivariate analysis confirmed the significant difference of SC variation in RPS, compared to the other groups (p < 0.001). No significance between LSL and OS (p = 0.826). No significant differences regarding motility (p = 0.8). CONCLUSIONS: Varicocele correction is confirmed useful in improving sperm parameters; sclerotization technique leads to a better sperm improvement compared to other studied procedures; improvement in seminal parameters is not affected by age of the patients treated.

INTRODUCTION: We present a refinement to our original technique in MtF gender reassignment surgery. Our goal was to construct a neoclitoris, which is wet and covered with urethral neoprepuce. Since 1995 more than 300 transgender MtF patients have been operated at our institution. Our refinement has been applied to 12 cases and showed both excellent functional and cosmetic results during midterm follow-up. PATIENTS AND METHODS: During 2010 several sex reassignment surgeries have been performed using our new technique that includes: bilateral orchiectomy, removal of corpora cavernosa of the penis, formation of the neourethra with neomeatus, neovaginoplasty by inversion of penoscrotal skin flaps, construction of the neoclitoris with preservation of the neurovascular bundle and exterior vulva formation. The refinement consists in creating a neoclitoris embedded in urethral mucosa using urethral flaps. These flaps are in continuity with the previously spatulated urethra. The urethral plate is further incised distally in a Y fashion. The urethral flaps are sutured around the neoclitoris to form a neo-urethroclitoris covered by urethral neoprepuce, which resembles a real female clitoris. The neoclitoris is positioned in the anatomical position of the male suspensory ligament of the penis that is also the natural anatomical position of the female clitoris. RESULTS: With this method we are able to construct a clitoris with a normal sensitivity embedded in urethral mucosa that remains wet and hairless. It can be easily stimulated during sexual intercourse, as most of the patients reported great satisfaction and ability to reach orgasm. DISCUSSION: We want to emphasize how both the cosmetic results and functionality of the neovagina and neoclitoris are important in this type of surgery for the quality of life of our patients. We are still far from a perfect surgical solution, but we are further improving our technique and follow our aims step by step.

OBJECTIVE: We evaluated the impact of removal of the tumour bearing testis on semen quality in men with testicular cancer and the effect of tumour histologic feature on semen quality. MATERIAL AND METHODS: We took into account the semen analysis before and after orchiectomy in 30 patients. RESULTS: The median sperm concentration before and after orchiectomy was respectively of 26.7 x 10(6)/ml (range: 0-120 x 10(6)/ml) and 16.6 x 10(6)/ml (range: 0-75 x 10(6)/ml) (p = 0.001). Median sperm concentration before and after surgery in patients affected by seminomatous cancer were respectively of 35.47 x 10(6)/ml and 23.99 x 10(6)/ml, while cases of non-seminomatous cancer were respectively of 17.9 x 10(6)/ml and 8.16 x 10(6)/ml. CONCLUSIONS: Semen quality at the diagnosis was poorer in patients affected by non-seminomatous testicular cancer. Sperm concentration deteriorated after orchiectomy. Our findings suggest that the most appropriate time for cryopreservation of semen is before orchiectomy.

To report and discuss four cases of renal cell carcinoma (RCC) in which preoperative investigations yielded contradictory results regarding the cranial extension of propagation of the tumor thrombus into the vena cava. An intraoperative ultrasound scan (IOU) was performed in all cases to identify the exact level of the tumor thrombus. We have performed an IOU of the vena cava in four patients with RCC propagation into the inferior vena cava. Preoperative investigations were performed in all patients and consisted of abdominal Ultrasound scan (USS), contrast enhanced CT scan and gadolinium enhanced MRI scan. Intraoperative ultrasound has identified correctly the cranial extension and the absence of tumor thrombus infiltration in all patients. The thrombus reached the suprahepatic vena cava in two cases and was confined to the infrahepatic vena cava in the remainder. Preoperative imaging investigation had failed to determine the correct cranial extension of the tumor thrombus in two patients.IOU is a very useful tool to accurately assess the precise extent of tumor thrombus and eventually the presence of vein wall infiltration. These data are of paramount importance to plan the optimal surgical approach. According to our experience this type of investigation identifies the cranial extent of a tumor thrombus inside the vena cava better than standard imaging techniques.
