BACKGROUND: Several biochemical and clinical markers have been proposed for selecting patients for active surveillance (AS). However, some of these are expensive and not easily accessible. Moreover, currently about 30% of patients on AS harbor aggressive disease. Hence, there is an urgent need for other tools to accurately identify patients with low-risk prostate cancer (PCa). PATIENTS: We retrospectively reviewed the medical records of 260 patients who underwent radical prostatectomy and were eligible for AS according to the following criteria: clinical stage T2a or less, prostate-specific antigen level < 10 ng/mL, 2 or fewer cores involved with cancer, Gleason score (GS) ≤6 grade, and prostate-specific antigen density < 0...

Kelley-Seegmiller syndrome (KSS) is a disorder that occurs when there is a partial deficiency of the enzyme hypoxanthine guanine phosphoribosyl transferase. It is involved in the metabolism of purines, clinically manifesting as hyperuricemia, hyperuricosuria, gout arthritis, and urolithiasis. The aim of this article is to present the case of a 33-year-old male with KSS, with left ureteral colic, and a 5-mm, 323-HU ureteral calculi, successfully managed with conservative management. It is critical to recognize that most urologists are not familiar with this inborn metabolic error and 75% of these patients will be affected by urolithiasis, thus making it a very critical and significant disease in our practice...
