In the Treatment of Lower Pole Kidney Stones Between 1-2 cm in Children, Which is the Best Approach? Retrograde Intrarenal Surgery or Mini Percutaneous Nephrolithotomy.

Objectives: Kidney stones are treated with many methods, but there is no consensus on which method should be preferred for 1-2 cm lower renal stones. In our study, we aimed to investigate the results of mini (Percutaneous Nephrolithotomy) PCNL and (Retrograde Intrarenal Surgery) RIRS in lower renal pole 1-2 cm stones.

Methods: Twenty-four mini PCNL and 55 RIRS patients were included in the study.

Evaluation of the Regeneration Effects of Systemically Applied Methylprednisolone and Vitamin B12 on Mental Nerve Crush Injury.

Aim: To evaluate the effects of methylprednisolone and vitamin B12 injection on the regeneration of the nerves after a mental nerve crush injury.

Material And Methods: A total of 40 albino Wistar rats have been randomly divided into four groups: group 1 (n=10): crushlike nerve damage was created by pinching the left mental nerve for 60 s with an aneurysm clip and intraperitoneally administered 1 ml of saline for 14 days; group 2 (n=10): the left mental nerve was pinched for 60 s with an aneurysm clip and intraperitoneally administered 2 mg/kg of methylprednisolone for 14 days; group 3, experimental group (n=10): the left mental nerve was pinched for 60 s with an aneurysm clip and intraperitoneally administered 2 mg/kg of vitamin B12 for 14 days; and group 4, experimental group (n=10): the left mental nerve was pinched for 60 s and intraperitoneally administered 2 mg/kg of methylprednisolone and 2 mg/kg of vitamin B12 for 14 days. All rats were sacrificed on the 28th postoperative day, and histopathological evaluation was performed.
