Fournier's gangrene is a potentially fatal emergency condition characterized by necrotizing fasciitis and supported by an infection of the external genital, perineal and perianal region, with a rapid and progressive spread from subcutaneous fat tissue to fascial planes. In this case report, a 52-year-old man, with a history of hepatitis C-virus (HCV)-related chronic liver disease and cocaine use disorder for which he was receiving methadone maintenance therapy, was admitted to the Emergency Department with necrotic tissue involving the external genitalia. Fournier's gangrene is usually due to compromised host immunity, without a precise cause of bacterial infection; here it is linked to a loco-regional intravenous injection of cocaine. A multimodal approach, including a wide surgical debridement and a postponed skin graft, was needed. Here we report this case, with a narrative review of the literature., Competing Interests: Conflict of interest Conflict of interest statement: Authors state no conflict of interest., (© 2019 Michele Del Zingaro et al., published by De Gruyter.)

Introduction: Renal artery embolization is performed before radical nephrectomy (RN) for renal mass in order to induce preoperative infarction and to facilitate surgical intervention through decrease of intraoperative bleeding. Moreover, in metastatic renal cancer it seems to stimulate tumour-specific antibodies, even if no established benefits in clinical response or survival have been reported. The role of preoperative renal artery embolization (PRAE) in management of renal masses has been often debated and its real benefits are still unclear. Nevertheless, in huge and complex renal masses, which are often characterized by a high and anarchic blood supply and rapid local invasion, radical nephrectomy can be challenging even for skilled surgeons. The aim of this prospective randomized study was to evaluate the effectiveness and safety of PRAE in complex masses by comparing perioperative outcomes of RN with and without PRAE., Materials and Methods: From December 2015 to May 2018 we enrolled prospectively 64 patients who underwent RN for localized (T2a-b) or locally advanced (T3 and T4) or advanced (N+, M+) renal cancers. Patients were divided in two groups. The first group included 30 patients who underwent PRAE; in the second group we enrolled 34 patients who did not undergo RN without PRAE. Perioperative outcomes in terms of operative time, blood loss, transfusion rate and length of hospitalization were evaluated. Statistical analysis was performed using GraphPad Prism 6.0 software., Results: Median blood loss was 250 ml (50-500) and 400 ml (50-1000) in the first and second group, respectively, with a statistically significant difference (p=0.0066). Median surgical time was 200 min (90-390) and 240 min (130-390) in PRAE and No-PRAE group (p=0.06), respectively. No major complications occurred after embolization. Overall complication rate in Group 1 and 2 was 46.7% (14/30) and 50% (17/34), respectively (p=0.34). No major complications occurred in both groups. The mean follow up was 21,5 months., Conclusions: Our results prove PRAE to be a safe procedure with low complications rate. To our experience, PRAE seems to be a useful tool in surgical management of a large mass and advanced disease., Competing Interests: Competing Interests The authors declare no conflict of interest., (© 2019 Giovanni Cochetti et al., published by De Gruyter.)

Surgical Site Infection (SSI) is the most frequent source of infection in surgical patients and the second most frequent cause of hospital-acquired infection. The primary aim of this prospective study was to compare SSI occurrences between minimally invasive surgery (MIS) and open urological surgery. Secondly, perioperative outcomes were evaluated in two different approaches. A consecutive group of 60 patients undergoing urological surgery were prospectively enrolled in a single high-volume center between May and October 2018. We included procedures that were performed by minimally invasive or traditional techniques. We evaluated and compared the incidence of SSI and perioperative outcomes in terms of intraoperative bleeding, post-operative complications, postoperative pain, patient satisfaction with the analgesic treatment, time to flatus, time of oral intake and mobilization, and length of hospital stay. The two groups were homogeneous with regard to demographic data. Superficial incisional SSIs were diagnosed in 10% of cases (3/30) in the second group and 0% in the first (p<0.05); space/organ SSIs developed in 4 patients, which were diagnosed by ultrasound scan and confirmed by abdominal CT: 1 patient (3.3%) in group 1 showed an infected lymphocele, whereas 1 case of infected lymphocele and 2 cases of pelvic abscess were detected in group 2 (10%, p<0.05). All the perioperative outcomes as well as were overall complication rate favored MIS (p<0.05). The use of minimally invasive techniques in urological surgery reduced the risk of SSI by comparison with a traditional approach. In addition, MIS was associated with better perioperative outcomes and a lower overall complication rate., Competing Interests: Conflict of interest Conflict of interest statement: Authors state no conflict of interest, (© 2019 Jacopo Adolfo Rossi de Vermandois et al., published by De Gruyter.)
