Percutaneous nephrolithotomy for large or multiple upper tract calculi and autosomal dominant polycystic kidney disease.
Percutaneous nephrolithotomy is standard therapy for upper tract calculi larger than 2 cm. However, the role of percutaneous nephrolithotomy in patients with autosomal dominant polycystic kidney disease has not been well evaluated. We report our experience with percutaneous nephrolithotomy in patients with autosomal dominant polycystic kidney disease. ⋯ Autosomal dominant polycystic kidney disease increased operative complexity, the need for multiple percutaneous access tracts and the likelihood of repeat endoscopy. Despite the altered anatomy percutaneous nephrolithotomy was a safe, efficacious approach for autosomal dominant polycystic kidney disease. At last followup there was no stone recurrence and renal function was stable.

Psychosocial phenotyping in women with interstitial cystitis/painful bladder syndrome: a case control study.
We characterized and compared psychosocial phenotypes in a female interstitial cystitis/painful bladder syndrome cohort and an age matched cohort without that diagnosis. ⋯ Patients with interstitial cystitis/painful bladder syndrome have significant cognitive and psychosocial alterations compared to controls.

Long-term outcomes of urgency-frequency syndrome due to painful bladder syndrome treated with sacral neuromodulation and analysis of failures.
We present our long-term experience with sacral neuromodulation devices placed in patients with painful bladder syndrome to determine whether the benefit decreases over time. ⋯ These patients appear to respond best to permanent quadripolar lead placement but long-term results do not appear to be independently affected by the method of test stimulation. Loss of benefit over time is not common.

ReviewContemporary applications and limitations of magnetic resonance imaging contrast materials.
Improvements in imaging technologies have dramatically increased the ability to accurately diagnose and treat many urological disease processes. As urological patients often have chronic kidney disease, the well characterized nephrotoxicity of contrast induced nephropathy when using iodine based contrast materials has long been a concern. With the development of gadolinium based contrast agents it seemed that the concern regarding nephrotoxicity had been resolved. In 1997 a new disorder, nephrogenic systemic fibrosis, appeared in patients with severe renal failure. Nephrogenic systemic fibrosis is a serious and potentially devastating disorder characterized by progressive thickening and hardening of the skin and other body tissues, and complicated by flexion contractures of the joints. ⋯ This review provides clarification of the gadolinium based contrast agent characteristics, tissue interactions that lead to the development of nephrogenic systemic fibrosis, prevention possibilities and available treatment options.
