ReviewUpdates on the use of intravesical therapies for non-muscle invasive bladder cancer: how, when and what.
Intravesical therapy has been an important aspect of the management of non-muscle invasive bladder cancer (NMIBC) for 40 years. Bacillus Calmette-Guerin (BCG) is considered standard of care for intermediate and high-grade non-invasive disease, yet understanding the nuances of subsequent intravesical therapy is important for any provider managing bladder cancer. Herein, we review the literature and describe optimal use of intravesical therapies for NMIBC. ⋯ Intravesical therapy remains the mainstay of treatment for NMIBC and bladder preservation. Intravesical induction BCG followed by maintenance therapy remains standard of care for intermediate and high-risk patients. Detailing the timing and characteristics of recurrence after intravesical therapy is crucial in determining subsequent treatment recommendations. Current clinical trials focus on systemic immunotherapy and enhancing the intravesical immune response by augmenting the delivery mechanism.

Visceral obesity in Asian living kidney donors significantly impacts early renal function after donor nephrectomy.
Obesity may be a risk factor for kidney donors to develop reduced renal function. The Framingham heart study suggested that visceral adipose tissue (VAT) confers a more adverse metabolic profile compared with subcutaneous adipose tissue (SAT). Asians tend to have a higher VAT composition and it is unclear if their kidney function is affected differently. We hypothesized that Asian living kidney donors who have visceral obesity are at a higher risk of renal function deterioration 1 year after donation. ⋯ Visceral obesity as defined by VAT > 100 cm2 at the level of the umbilicus on cross-sectional imaging, may have a significant impact on early renal function after donor nephrectomy. Adiposity markers, as measured by cross-sectional CT imaging, may be incorporated into routine pre-operative kidney donor workup.

Superselective vesical artery embolization in the management of intractable hematuria secondary to hemorrhagic cystitis.
To evaluate the efficacy and outcome of superselective vesical arterial embolization in the management of severe intractable hematuria secondary to hemorrhagic cystitis. ⋯ Superselective vesical artery embolization is a safe and effective procedure in controlling intractable life-threatening hematuria in a select group of patients who have failed conventional treatment protocols. This procedure may be considered as the treatment of choice since it usually obviates the need for emergency surgery in these severely ill patients.
