Oxidative stress and phenotype frequencies of paraoxonase-1 in teratozoospermia.

Oxidative stress causes infertility in men by affecting especially sperm morphology. The aim of the study was to examine the frequencies of paraoxonase-1 (PON1) phenotypes and the serum PON1, arylesterase, total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index, catalase and thiol levels in teratozoospermic infertile men and normospermic fertile men. The study included 184 teratozoospermic infertile men and 72 normospermic fertile men.

Trifecta Outcomes of Laparoscopic Partial Nephrectomy for T1a and T1b Renal Tumors: A Single-Center Experience in a Tertiary Care Institution.

To assess the effectiveness and safety of laparoscopic partial nephrectomy (LPN) in T1a and T1b renal tumors using "Trifecta" in partial nephrectomy and determine the predictive factors in respect to the criteria that constitute Trifecta. We retrospectively analyzed the data harvested from the patients who underwent LPN for T1a or T1b tumors. Preoperative, perioperative, and postoperative outcomes were evaluated and analyzed.

Comparison of Scoring Systems in Predicting Success of Percutaneous Nephrolithotomy.

Background: Scoring systems are useful to inform the patients about the success and complication rates of the operation prior the surgery.

Aims: To determine the applicability of the popular scoring systems (Guy’s, stone size, tract length, obstruction, number of involved calices, and essence/stone density and Clinical Research Office of the Endourological Society) by means of examining preoperative data of patients treated with percutaneous nephrolithotomy.

Study Design: Cross sectional study.
