En-bloc resection of non-muscle invasive urinary bladder tumors using low power Holmium laser-A new promise.

Introduction: Urinary bladder tumors are one of the most common urological malignancies. Traditionally, it has been initially managed with conventional trans-urethral resection of urinary bladder tumors (cTURBT) which has certain drawbacks and complications. Efforts have been made to find newer methods for management.

Prospective Comparative Analysis of Supine Versus Prone Percutaneous Nephrolithotomy in Patients with Complex Renal Stone Disease and Difficult Anatomy.

Objective:  In complex renal stone disease, few studies have shown that supine percutaneous nephrolithotomy (PCNL) is not inferior to prone PCNL. In our study, we evaluated the safety and efficacy of supine versus prone PCNL in patients with complex renal stone disease and patients with difficult anatomy.

Methods:  We prospectively analyzed 106 patients over 15 months from October 2022 to December 2023 and divided them as group S (Calcutta position supine arm) and group P (classical prone arm) by simple randomization.
