Ultramini-percutaneous nephrolithotomy versus retrograde intrarenal surgery in the treatment of 10-30 mm calculi: a randomized controlled trial.

The surgical management of renal stones 10-30 mm is usually performed with percutaneous nephrolithotomy (PCNL) and retrograde intrarenal surgery (RIRS). Standard form of percutaneous nephrolithotomy has paved the way for miniaturized PCNL in many centres. We wanted to evaluate the efficacy, safety and the cost-effectiveness of ultramini-percutaneous nephrolithotomy (UMP) versus RIRS in the treatment of renal stones with stone burden 10-30 mm.

Obstructive Uropathy as an Initial Presentation of Primary Myelofibrosis: Case Report and Review of Literature.

Primary myelofibrosis (PMF) is a rare hematological disorder associated with progressive cytopenia and extra-medullary hematopoiesis. Acute kidney injury in this disease has been reported from diverse etiologies such as renal and peri-renal extramedullary hematopoiesis and tumor lysis syndrome. We report a patient who presented with obstructive uropathy from uric acid stones who was incidentally diagnosed with PMF during workup for persistent thrombocytosis and leukocytosis.
