Iatrogenic injuries of the intrarenal arterial system include pseudoaneurysms and fistulas. They can cause hematuria and life-threatening hemodynamic instability, and therefore should be treated promptly. Endovascular treatment is recommended for these cases due to its effectiveness. ⋯ All patients were successfully treated, and all but one had excellent follow-ups. One patient suffered from disseminated intravascular coagulation secondary to transfusion and died after the procedure. We think glue embolization is a safe and effective treatment for this group of patients and present our experience along with the technical approach.

Multicenter Study
The clinical features of Fournier's gangrene and the predictivity of the Fournier's Gangrene Severity Index on the outcomes.
Fournier's gangrene (FG) is a rare, rapidly progressive, fulminant form of necrotizing fasciitis of the genital, perianal and perineal regions. Several factors have been reported to contribute to the clinical outcomes. The primary aims of this study were to examine the clinical features of patients with FG and evaluate the predictivity of the Fournier's Gangrene Severity Index (FGSI) score on the outcomes. ⋯ Regression analysis showed a FGSIS score of 10.5 as the cut-off to the outcome. Based on these results, we conclude that a patient's metabolic status and the extent of disease at presentation are the most important factors determining the prognosis of FG. The FGSI score may be considered as an objective and simple tool to predict the outcome in the patient with FG and should be used in further studies of FG patient series for comparison purposes.

Randomized Controlled Trial Multicenter Study
Safety and tolerability of extended-release oxybutynin once daily in urinary incontinence: combined results from two phase 4 controlled clinical trials.
Early studies of extended-release oxybutynin in patients with overactive bladder used adjusted-dose regimens ranging from 5 to 30 mg/day to achieve an optimal balance of efficacy and tolerability. The safety and tolerability of extended-release oxybutynin at a fixed dose of 10 mg once daily (commonly prescribed in clinical practice) is reported using pooled data from 2 multicenter, randomized, double-blind, parallel-group trials with a similar study design. One study compared extended-release oxybutynin with immediate-release tolterodine 2 mg bid. ⋯ Most AEs (>90%) were mild or moderate in intensity in all treatment groups. The proportion of patients who discontinued study medication due to AEs was 6.1, 4.8, and 7.8% in the extended-release oxybutynin, extended-release tolterodine, and immediate-release tolterodine groups, respectively. In total, 1.2, 1.0, and 1.6% of patients in the extended-release oxybutynin, extended-release tolterodine, and immediate-release tolterodine groups, respectively, discontinued study medication due to dry mouth.

Herein, we report on a paediatric patient with mitochondrial encephalopathy, lactic acidosis and stroke-like episodes (MELAS) who was hospitalized for acute on chronic renal insufficiency, seizures and deterioration of the level of consciousness. She also had hypertension, hypothyroidism and nephrotic range proteinuria. Kidney biopsy revealed many sclerotic glomeruli and focal segmental glomerulosclerosis (FSGS). ⋯ The histopathological features of the renal biopsy suggested that the aetiology of the FSGS may have been secondary to chronic renal injury rather than from a primary immunologic cause. Moreover, our case is unique in that, the coexistence of MELAS, hypothalamic hypothyroidism and FSGS has not been reported in the past. The purpose of this report is to increase the awareness of health-care professionals, especially in the fields of paediatrics, neurology, endocrinology and nephrology, regarding the manifestations and complications of MELAS.

The necessity of a postoperative chest tube for the treatment of pneumothorax after a radical nephrectomy is controversial. ⋯ Iatrogenic pleural rents treated without a postoperative chest tube show a significant decrease in postoperative complications of pneumonia and atelectasis, pain score and length of hospital stay. These patients show no significant increases in postoperative complications; therefore, it appears that postoperative chest tube placement after a pleural injury occurs is of no advantage.
