A multistep approach to manage Fournier’s gangrene in a patient with unknown type II diabetes: surgery, hyperbaric oxygen, and vacuum-assisted closure therapy: a case report

IntroductionFournier’s gangrene is an infectious necrotizing fasciitis of the perineum and genital regions and has a high mortality rate. It is a synergistic infection caused by a mixture of aerobic and anaerobic organisms and predisposing factors, including diabetes mellitus, alcoholism, malnutrition, and low socioeconomic status. We report a case of Fournier’s gangrene in a patient with unknown type II diabetes submitted to 24-hour catheterization 15 days before gangrene onset.Case presentationThe patient, a 60-year-old Caucasian man, presented with a swollen, edematous, emphysematous scrotum with a crepitant skin and a small circle of necrosis. A lack of resistance along the dartos fascia of the scrotum and Scarpa’s lower abdominal wall fascia combined with the presence of gas and pus during the first surgical debridement also supported the diagnosis of Fournier’s gangrene. On the basis of the microbiological culture, the patient was given multiple antibiotic therapy, combined hypoglycemic treatment, hyperbaric oxygen therapy, and several surgical debridements. After five days the infection was not completely controlled and a vacuum-assisted closure device therapy was started.ConclusionsThis report describes the successful multistep approach of an immediate surgical debridement combined with hyperbaric oxygen and negative pressure wound therapy. The vacuum-assisted closure is a well-known method used to treat complex wounds. In this case study, vacuum-assisted closure treatment was effective and the patient did not require reconstructive surgery. Our report shows that bladder catheterization, a minimally invasive maneuver, may also cause severe infective consequences in high-risk patients, such as patients with diabetes.

Prospective Randomized Study of Radiofrequency Versus Ultrasound Scalpels on Functional Outcomes of Laparoscopic Radical Prostatectomy

BACKGROUND AND PURPOSE Surgical treatment of patients with prostate cancer currently involves laparoscopic radical prostatectomy (LRP) or robot-assisted LRP. Continence and nerve-sparing procedures in these techniques are supported by dissection and hemostatic surgical devices powered by different types of energy. The aim of this study was to assess recovery of continence and erectile function after laparoscopic extraperitoneal radical prostatectomy comparing two surgical devices for dissection and hemostasis-radiofrequency (RF) and ultrasound (US) scalpels. PATIENTS AND METHODS A total of 132 men with localized prostate cancer were prospectively enrolled and scheduled for extraperitoneal LRP. Patients were randomly assigned to the RF group (LigaSure; n=66) or the US group (UltraCision; n=66). Outcomes were measured by the self-administered questionnaires (International Consultation on Incontinence Questionnaire-Urinary Incontinence [ICIQ-UI] and International Index of Erectile Function 5 [IIEF 5]) 15 days before surgery, 90 and 180 days after prostatectomy to assess recovery of urinary continence and erectile function. RESULTS No significant difference was found between the two groups regarding operative time, intra- and perioperative complications, or time of hospital stay. At 180 days after surgery, patients in the RF-treated group showed better recovery in terms of continence and erectile function compared with patients in the US group (ICIQ-UI: p=0.0016; IIEF 5: p=0.0352). CONCLUSIONS The use of the RF scalpel provided better functional outcomes compared with the US scalpel in patients undergoing extraperitoneal LRP. This might be attributed to the low contiguous damage of those tissues, which are not directly involved in dissection and hemostasis, achieved using the RF device.

Synchronous primary neoplasms of the bladder, skin and breast in a male patient: a case report

The incidence of multiple primary malignant neoplasms increases with age, reflecting an increase in overall cancer risk in older patients. Cases of two or more concurrent primary cancers are still rare, although its incidence is increasing. Here, we report the case of a 57-year-old man who was referred to our institution with synchronous squamous cell carcinoma of the skin on the forehead, infiltrating ductal carcinoma of the breast, and transitional cell carcinoma of the urinary bladder. To the best of our knowledge, this is the first reported case in literature of this combination of primary neoplasms.

Are early continence recovery and oncologic outcomes influenced by use of different devices in prostatic apex dissection during laparoscopic radical prostatectomy

BACKGROUND AND PURPOSE Treatment of patients with prostate cancer has evolved considerably in the last decade, especially in terms of minimization of the negative impacts on erectile function and continence to ensure good quality of life for treated patients. New surgical devices, such as dissectors and hemostatic scalpels, allow precise definition of the surgical field with finer dissection of the anatomic structures, with subsequent reductions in operative times and better oncologic and functional outcomes. Although monopolar scissors (MS) are still widely used, radiofrequency (RF) and ultrasound (US) scalpels have been introduced recently in laparoscopic radical prostatectomy (LRP). Despite the widespread use of these scalpels, however, few studies have compared these devices in terms of oncologic and functional outcomes after radical prostatectomy. The present study aimed to prospectively assess the impact of MS, RF, and US scalpels on margin status at apex, and recovery of urinary continence and erectile function in patients undergoing extraperitoneal LRP. PATIENTS AND METHODS A total of 150 men were prospectively enrolled between September 2009 and April 2013 and postoperatively evaluated for continence and clinical factors. RESULTS There were no differences in terms of operative times (P=0.9433), blood loss (P=0.9681), apical margin positivity (P=0.3965) or postoperative hospital stay (P=0.9257) among the groups. Moreover, no differences in the functional outcome scores, as evaluated by the International Consultation on Incontinence self-administered Questionnaire, at 1, 3, and 6 months postsurgery were observed. CONCLUSION Our study represents the first evaluation of continence recovery in LRP with respect to different devices used for prostatic apex dissection. We found that the oncologic, functional, and operative outcomes were similar between these different devices during LRP, with no scalpel demonstrating superiority in continence recovery.

Combined laparoscopic pyelolithotomy and endoscopic pyelolithotripsy for staghorn calculi: long-term follow-up results from a case series

Purpose: Staghorn renal stones are a challenging field in urology. Due to their high recurrence rates, particularly those associated with an infective process, a complete removal is the ultimate goal in their management. We report our experience with a combined approach of laparoscopic pyelolithotomy and endoscopic pyelolithotripsy, the stone clearance rate, and long-term, follow-up outcomes. Methods: From June 2012 to October 2014, nine adult patients with large staghorn renal calculi (mean size, 7.2 cm; range, 6.2–9.0 cm) underwent a combined laparoscopic and endoscopic approach. The technique comprised laparoscopic pyelolithotomy and holmium-YAG laser stone fragmentation with the use of a flexible cystoscope introduced through a 12 mm trocar. Results: The average operative time was 140 min (range, 90–190 min). The mean estimated hemoglobin loss was 0.6 mmol/l (range 0.5–0.7 mmol/l). None of the patients required an open- surgery conversion. The mean hospital stay was 4 days (range, 2–6 days). A computed tomography urogram control at 6 months of follow up did not show any stone recurrence. Conclusions: Laparoscopic pyelolithotomy combined with endoscopic pyelolithotripsy could be a therapeutic option in cases where mini-invasive procedures, that is, extracorporeal shock wave lithotripsy, ureteroscopic lithotripsy, and percutaneous nephrolithotomy (PCNL) have failed. This technique has a high stone-clearance rate (75–100%) comparable with open surgery and PCNL. However, it could be technically demanding and should be performed by skilled laparoscopy surgeons.

Synchronous urinary tract metastases from breast cancer

Breast carcinoma has a metastatic potential to any organ system. However, breast carcinoma metastases to the urinary tract have very rarely been described. The authors present the case of a patient with a synchronous right ureteral and vesical metastasis of a breast cancer. This is the unique case reported in Literature of synchronous urinary metastatic localization from breast invasive lobular carcinoma.

Bone metastases from bladder perivascular epithelioid cell tumor – an unusual localization of a rare tumor: a case report

IntroductionPerivascular epithelioid cell tumors are mesenchymal tumors composed of histologically and immunohistochemically distinctive perivascular epithelioid cells. This type of tumor is rare but bladder localization is even rarer.Case presentationA case of bone metastatic bladder perivascular epithelioid cell tumor in a 65-year-old Caucasian man treated with surgery and chemotherapy is described and compared with other reports in the literature.ConclusionsThe rarity of perivascular epithelioid cell tumors hinders the development of a standard therapeutic approach, and thus requires case report descriptions. There is a need for cooperative studies to enlarge the case series and establish the best treatment strategy for this rare disease.

Laparoscopic radical prostatectomy after previous transurethral resection of prostate using a catheter balloon inflated in prostatic urethra: Oncological and functional outcomes from a matched pair analysis

To explore the surgical, oncological and functional outcomes of laparoscopic radical prostatectomy in patients who have undergone transurethral resection of the prostate, using a catheter balloon inflated in the prostatic urethra.

MP76-20 IMPACT OF BARIATRIC SURGERY ON OVERACTIVE BLADDER SYMPTOMS IN A COHORT OF OBESE PATIENTS: A PROSPECTIVE INVESTIGATION

Epidemiological data show an association between obesity and lower urinary tract symptoms (LUTS), especially urinary frequency, urinary urgency and urinary incontinence. Patients with pathologic obesity satisfying specific criteria may be submitted to bariatric surgery which provides a significant reduction of body mass index (BMI) improving quality of life. The aim of this prospective pilot study was to assess the impact of bariatric surgery in a cohort of obese patients suffering from overactive bladder (OAB) symptoms.

Incidental diagnosis of a retroperitoneal schwannoma in a patient with chronic leukemia undergoing prostatic biopsy

We present a case of retroperitoneal schwannoma incidentally diagnosed in a patient undergoing surgical drainage of a pelvic abscess as a complication of a prostatic biopsy. A 50-year-old male, suffering from lymphatic leukemia, came to our observation due to lichen ruber planus and ejaculatory pain. The patient underwent a trans-perineal ultrasound-guided biopsy of the right seminal vesicle and of a hypoechoic area documented by ultrasonography. 48 hours after the procedure, the patient had developed: cold sores, shortness of breath with dyspnea, and high fever (40°C). The patient was hospitalized, underwent an emergency CT which documented a right presacral and pararectal liquid mass (abscess). The patient underwent emergency laparotomy and drainage of the abscess. The lesion histological examination revealed a retroperitoneal schwannoma with inflammatory phenomena and hyperplasic lymphadenitis. The retroperitoneal schwannoma is a silent disease whose only clinical manifestation coincides with the compression of adjacent anatomical structures. In many cases, the symptoms, even if present, as in this case (ejaculatory pain with compression of the seminal vesicle), are non-specific, thus delaying diagnosis and the therapeutic approach.
