Effect of intravenous pentoxifylline in inflammatory response in patients undergoing nephrolithotomy.

Purpose: To determine the potential efficacy of intravenous (IV) infusion of pentoxifylline (PTX) before nephrolithotomy on attenuating plasma level of the tumor necrosis factor (TNF)-alpha and interleukin (IL)-1, and to investigate whether it prevents postoperative pain.

Patients And Methods: In a randomized, double-blind, placebo-controlled study, 32 patients (American Society of Anesthesiologists physical status 1 and 2) who were undergoing general anesthesia for nephrolithotomy were randomized to receive intravenous PTX (500 mg in 500 mL saline for 2 hours followed by 700 mg in 1000 mL saline for 6 hours), or placebo (1500 mL saline) before induction of the anesthesia. Two venous blood samples were obtained 10 minutes before PTX or placebo infusion and after surgery at 24 hours for laboratory examination.

Comparison of systemic stress responses between percutaneous nephrolithotomy (PCNL) and open nephrolithotomy.

Background And Purpose: Stimulation of patient's immune response and therefore increasing inflammatory indices in patients who underwent invasive treatment methods for kidney stone removing can be predictable. In the present study, we tried to evaluate the differences of inflammatory indices in percutaneous nephrolithotomy (PCNL) and compared them with open stone surgery in patients with kidney stones.

Patients And Methods: In a clinical trial study, 15 adult patients that scheduled to undergo PCNL and 15 patients who were candidate for open stone surgery matched for sex and age were included.

Role of sexual intercourse in hematuria and proteinuria in males and females.

Objective: A probable association has been proposed between sexual intercourse and hematuria and proteinuria in either sex. The present study was to assess the role of sexual intercourse in hematuria and proteinuria in immediate dipstick urine test and morning urine sample analysis and whether sexual intercourse might be a cause of microscopic hematuria and proteinuria.

Material And Methods: Forty-two healthy married adult volunteers (27 male and 15 female; age range 20-48) were enrolled in a prospective clinical trial.

Role of postcircumcision mucosal cuff length in lifelong premature ejaculation: a pilot study.

Introduction: Premature ejaculation (PE) is the most prevalent sexual dysfunction among men. Several theories about its etiology have been made. One of the conflicting factors is the effect of circumcision on ejaculation, and there are some concerns about leaving so much mucosa during circumcision.
