Contribution of stone size to chronic kidney disease in kidney stone formers.

Objectives: To determine whether stone burden correlates with the degree of chronic kidney disease in kidney stone formers.

Methods: A total of 97 extracorporeal shockwave lithotripsy candidates aged 18 years and older were included. Size, number and location of the kidney stones, along with cumulative stone size, defined as the sum of diameters of all stones) were determined.

The safety and efficacy of percutaneous nephrolithotomy for management of large renal stones in single- versus double-functioning kidney patients.

Purpose: To demonstrate the safety and efficacy of percutaneous nephrolithotomy (PCNL) for management of large renal stones between single-functioning kidney and double-kidney patients.

Patients And Methods: Thirty single-functioning kidneys and 30 double-kidney patients with a mean age of 38.5 (±15.
