Laparoscopic pyelolithotomy: An emerging tool for complex staghorn nephrolithiasis in high-risk patients.

Objectives: To evaluate the effectiveness of laparoscopic pyelolithotomy (LP) for staghorn stones (>3-4 cm) in patients with chronic liver disease or coronary artery disease.

Patients And Methods: In all, 49 patients underwent LP; they were divided into four groups, with stones in group 1 in the renal pelvis only, in group 2 in the renal pelvis and one calyx, in group 3 in the renal pelvis and two calyces, and in group 4, in the renal pelvis and more than two calyces. Patient demography, stone characteristics, surgical outcomes and complications were evaluated.

Combined surgical intervention and medical management in a case of atypical idiopathic retroperitoneal fibrosis.

Idiopathic retroperitoneal fibrosis (RPF) is one of the causes of obstructive uropathy. This disease, ever since its original description in 1948, has undergone much trial and error in its management. We present a case of a rare type of idiopathic RPF causing obstructive uropathy, which is perirenal and different from the classical RPF seen around the great vessels.
