SWOG S0353: Phase II trial of intravesical gemcitabine in patients with nonmuscle invasive bladder cancer and recurrence after 2 prior courses of intravesical bacillus Calmette-Guérin.
Prior phase II studies of intravesical gemcitabine have shown it to be active and well tolerated, but durable responses in patients with nonmuscle invasive bladder cancer who have experienced recurrence after bacillus Calmette-Guérin treatment are uncommon. We performed a multi-institutional phase II study within the SWOG (Southwest Oncology Group) cooperative group to evaluate the potential role of gemcitabine induction plus maintenance therapy in this setting. ⋯ Intravesical gemcitabine has activity in high risk nonmuscle invasive bladder cancer and offers an option for patients with recurrence after bacillus Calmette-Guérin who are not suitable for cystectomy. However, less than 30% of patients had a durable response at 12 months even with maintenance therapy.

Comparative StudyA survey to assess body and self-image in individuals with bladder exstrophy: a call for psychosocial support.
Although research in patients with urological conditions indicates that functional limitations, pain, limited mobility and social restrictions can impact self-image, to our knowledge the influence of the visibility of the condition has not been examined. We assessed body image and self-image at school age through young adulthood in patients with bladder exstrophy compared to patients with kidney stones. ⋯ Differences in the visibility and privacy of the 2 conditions likely explain the discrepancy between the groups. Findings may call for an individual approach to assessing issues related to self-esteem and identity in patients with bladder exstrophy and may highlight the importance of receiving psychosocial support.

ReviewDimensions of sensation assessed in urinary urgency: a systematic review.
Urinary urgency is an adverse sensory experience. Confirmation of the multidimensional nature of other adverse sensory experiences such as pain and dyspnea has improved the understanding of neurophysiological and perceptual mechanisms leading to innovations in assessment and treatment. It has been suggested that the sensation of urgency may include multiple dimensions such as intensity, suddenness and unpleasantness. In this systematic review we determine which dimensions of sensation have been assessed by instruments used to measure urinary urgency. ⋯ The hypothesis that urinary urgency is multidimensional is supported by the range of dimensions assessed with available instruments. To clarify the nature of urinary urgency compared with the normal desire to void, prospective studies are required to determine whether sensory dimensions are distinct, and which may delineate between normal and pathological sensation.

Comparative StudyUrinary NGAL levels correlate with differential renal function in patients with ureteropelvic junction obstruction undergoing pyeloplasty.
Recent investigations described the use of NGAL, a sensitive biomarker for kidney injury, in the setting of ureteropelvic junction obstruction. We prospectively evaluated urinary NGAL levels in the affected renal pelvis and bladder of children with ureteropelvic junction obstruction undergoing unilateral dismembered pyeloplasty. Our hypothesis was that higher NGAL in the kidney and bladder would correlate with decreased ipsilateral differential function. ⋯ Bladder NGAL is increased in children with ureteropelvic junction obstruction. Renal pelvic and bladder normalized urinary NGAL levels correlate inversely with the relative function of the affected kidney in cases of unilateral ureteropelvic junction obstruction.
