Squamous Cell Carcinoma Penis in a Case of Urethral Stricture Due to Lichen Sclerosus Balanitis Xerotica Obliterans: A Case Report and Review of Literature.

Penile carcinoma is considered a delayed sequel of lichen sclerosus. It is important to recognize this not so uncommon complication in time as survival of patients with Squamous Cell Carcinoma (SCC) depends on early diagnosis and treatment. We describe a case of a 49-year-old male presenting with urethral stricture due to lichen sclerosus.

Stepwise case selection using Guy's stone score reduces complications during percutaneous nephrolithotomy training.

Introduction: Traditional percutaneous nephrolithotomy (PCNL) training involved subjective award of cases to the trainee. We restructured this according to the Guy's stone score (GSS) such that each trainee stepwise completed 25 cases of each grade before progressing. This study compares the outcomes of training with traditional versus stepwise approach.

Comparative testing of reliability and audit utility of ordinal objective calculus complexity scores. Can we make an informed choice yet?

Objectives: To assess the reliability of the Guy's Stone Score, the Seoul National University Renal Stone Complexity (S-ReSC) score and the S.T.O.
