American Association for the Surgery of Trauma grade 4 renal injury substratification into grades 4a (low risk) and 4b (high risk).
We identified computerized tomography findings associated with the need for urgent intervention for hemostasis after traumatic renal injury to update and refine the American Association for the Surgery of Trauma Organ Injury Scale for renal trauma. ⋯ On radiography a large perirenal hematoma, intravascular contrast extravasation and medial renal laceration are important risk factors associated with the need for urgent hemostatic intervention after renal trauma. Assessing these computerized tomography characteristics collectively shows that American Association for the Surgery of Trauma grade 4 renal injuries can and should be substratified into grades 4a (low risk) and 4b (high risk).

Prognostic value of body mass index in Korean patients with renal cell carcinoma.
Whether body mass index is a prognostic factor in patients with renal cell carcinoma continues to be debated. We investigated the association between body mass index, and clinical/pathological features and prognosis in a large cohort of Korean patients with renal cell carcinoma. ⋯ Our findings suggest that overweight and obese Korean patients with renal cell carcinoma have more favorable pathological features and a better prognosis than those with a normal body mass index.

Dipstick pseudohematuria: unnecessary consultation and evaluation.
While many primary care providers advocate routine screening urinalyses, a heme positive dipstick test often leads to a false-positive diagnosis of hematuria, or pseudohematuria. Thus, American Urological Association guidelines recommend urological evaluation for asymptomatic patients only for at least 3 red blood cells per high power field in 2 of 3 microscopic urinalyses. We determined the percentage of patients referred for asymptomatic hematuria undergoing unnecessary consultation and studies. ⋯ Positive dipstick heme tests should always be confirmed by microscopic urinalysis before urological referral or evaluation. Education of referring physicians regarding the American Urological Association guidelines could possibly help limit costly and potentially harmful, unnecessary evaluation of patients without true microhematuria.

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.
