Radiologic Relation of the Colon to the Trajectory of Percutaneous Nephrolithotomy Access in Prone Versus Flank-free Modified Supine Position: A Prospective Study of Intra and Interindividual Influencing Factors.

Objective: To compare the distance between the colon and the trajectory of percutaneous nephrolithotomy (PCNL) access both in prone and flank-free modified supine (FFMS) positions as measured on computed tomography and to study the effect of age, gender, BMI, side, and previous renal surgery as influencing factors.

Patients And Methods: In this prospective study, we included 367 patients scheduled for PCNL. All patients underwent low dose abdominal computed tomography both in prone and FFMS positions.

Silodosin in the treatment of distal ureteric stones in children: A prospective, randomised, placebo-controlled study.

Objectives: To evaluate the possible role of silodosin (a highly selective α-adrenoceptor antagonist) in facilitating the passage of distal ureteric stones (DUS) in children, as the role of α-blockers as medical expulsive therapy is well known in adults.

Patients And Methods: In all, 40 paediatric patients (27 boys and 13 girls) diagnosed with unilateral, single, radiopaque DUS of <10 mm were included in the study. Their mean (SD, range) age was 8.

Single versus multiple instillation of povidone iodine and urographin in the treatment of chyluria: A prospective randomised study.

Objective: To compare the safety, efficacy and complications of single vs multiple instillations of povidone iodine (PI) and urographin as a sclerosing agent in the treatment of chyluria.

Patients And Methods: The study included 58 patients diagnosed with chyluria between March 2006 and January 2013. The inclusion criteria were either severe attacks of chyluria or patients with mild-to-moderate chyluria who had failed conservative treatment.
