Effect of histopathologic characteristics on pseudocapsular invasion in the case of partial nephrectomy for renal tumours.

Objective: It is aimed to define the existence of pseudocapsular structure on renal tumours, illuminate the relation between pseudocapsular invasion and Fuhrman grade histological type that are among histopathologic prognostic risk factors and determine the relation between surgical margin positivity and existence of pseudocapsular invasion.

Do the etiological factors in artificial urinary sphincter reimplantation cases affect success and complications?

Background/aim: The artificial urinary sphincter (AUS) is still one of the best options for incontinence treatment.

Purpose: To histopathologically and biochemically evaluate the hypothesis that tadalafil increases the uptake of a second medication into the prostate tissue by increasing the blood supply in the prostate.

At the end of 10 days of drug administration in Group1, 2, and 3, and at the end of 30 days of drug administration in Group 4 and 5,blood samples were collected from rats and analyzed for serum androgen levels.

Posttraumatic High-Flow Nonischemic Priapism.

Priapism is an uncommon disorder, and nonischemic priapism is seen less frequently in children, generally after trauma. Although it seems to be an advantage that urgent intervention is not required because of no cavernous ischemia, it is likely to be misdiagnosed because of the asymptomatic potential. We aimed to present a case of posttraumatic nonischemic priapism.

An evaluation of the protective effect of esomeprazole in an experimental model of renal ischemia-reperfusion.

Purpose: The ischemia and subsequent reperfusion (IR) which occurs in partial nephrectomy used in the treatment of renal tumors causes loss of parenchyma in the damaged kidney.
