Assessment of the choroidal thickness, central macular vascular and optic disk perfusion in migraine patients with optical coherence tomography angiography.

Background: Comparing the central choroidal thickness (CCT) and the perfusion of the macula and optic disk in patients with migraine and control group participants using optical coherence tomography angiography (OCTA).

Methods: A total of 38 patients diagnosed with migraine and 32 healthy controls were recruited. OCTA scans were performed on all participants.

Comparison of miniaturized percutaneous nephrolithotomy and retrograde intrarenal surgery: Which is more effective for 10-20 mm renal stones in children?

Objective: To compare miniaturized percutaneous nephrolithotomy (mini-PNL) and retrograde intrarenal surgery (RIRS) in children with 10-20 mm renal stones. MATERIALS AND METHODS: Between 2015 and 2019, 63 pediatric patients aged under 16 years who under went mini-PNL and RIRS for the treatment of kidney stones sized 10-20 mm were analyzed retrospectively. The mini-PNL group (n=30) was defined as group 1 and the RIRS group (n=33) was defined as group 2.
