Percutaneous nephrolithotomy: Three-needle technique on two planes. Cury's technique.

Introduction: Percutaneous nephrolithotomy is the main type of surgery indicated for kidney stones larger than 2 cm. The present study describes a three-needle technique for percutaneous nephrolithotomy on two planes.

Surgical Technique: The patient is first placed in the lithotomy position for cystoscopy, which guides the ureteral and urethral catheter.

Pyelolithotomy in a Patient with Complete Coraliform Calcification Induced by a Double-J Ureteral Stent.

The placement of a double-J ureteral stent enables the treatment of upper urinary tract obstruction. Despite advances, forgetting the stent favors the occurrence of calcification, leading to increased morbidity rates, lawsuits, and a financial burden on the healthcare system. This paper describes a successful pyelolithotomy for the removal of a calcified double-J ureteral stent.
