The role of plain radiography in predicting renal stone fragmentation by shockwave lithotripsy in the era of noncontrast multidetector computed tomography.

Purpose: The objective of this study is to determine if plain radiography has a role in prediction of stone fragmentation by shockwave lithotripsy (SWL).

Patients And Methods: Our study included 106 patients undergoing SWL for renal stones. Based on plain radiography criteria, stones were classified according to density, homogeneity, and outline.

Stenting versus non-stenting after non-complicated ureteroscopic manipulation of stones in bilharzial ureters.

Background: Stents were used routinely after ureteroscopy to prevent postoperative ureteral obstruction. However, because of the recognized complications of stents, non-stenting is the new trend after uncomplicated ureteroscopy. The wall of the bilharzial ureter is characteristically thick and may be calcified.
