Objective: The aim of this study was to compare the success and complication rates of retrograde intrarenal surgery for lower calyceal renal stones performed with novel tip-bendable suction ureteral access sheaths and standard ureteral access sheaths.
Methods: Between March 2023 and March 2024, a total of 88 patients underwent retrograde intrarenal surgery for lower renal calyceal stones smaller than 20 mm. Based on the access sheath used, patients were divided into two groups: Group 1 (n=43) included patients treated with novel tip-bendable suction ureteral access sheaths and Group 2 (n=45) included patients treated with standard ureteral access sheaths.
Background: Bioengineering products can help bone tissue regeneration.
Objective: There is an ongoing research for more effective biomaterials in bone regeneration. Chitosan (Ch) grafted stearic acid (Ch-g-Sa) polymer was synthesized and its usability as a putty was evaluated in this study.
The purpose of this study is to experiment an assessment method using eye tracking technology in simulator based electronic navigation training of ship officers who play a critical role in maritime accidents. The maritime industry focuses on human factor developing and improving regulations, training requirements and technology to prevent marine casualties. The mandatory use of simulations in maritime training as per international regulations includes competency assessment as a vital process.

Materials And Methods: Patients were enrolled using block randomization between February 2016 and July 2016. Patients with renal stones >2 cm confirmed via noncontrast-enhanced CT were included.
Background: Telemedical Assistance Service (TMAS) is very important for seafarers and passengers who are far from full-fledged health services. This study aimed to determine the frequency of using Turkish TMAS by seafarers and other patients and to compare the given services.
Materials And Methods: The data obtained from calls to Turkish TMAS in between 2014 and 2017 are composed of 5080 calls.
Introduction: We examined the effect of seasonal variation on sexual behavior and its relationship with testosterone levels. The existence of the inhibiting effect of cold stress on sexual behavior and testosterone levels was our hypothesis.
Material And Methods: A total of 80 cases, aged between 20 and 35 years old, were enrolled.
Subcutaneous emphysema is a very rare and good-natured complication after transurethral resection of prostate (TURP). It has been reported as colon perforation, diverticulitis, and bladder perforation associated complication previously. We report the first case of a wide subcutaneous emphysema due to microperforations of prostatic capsule, without a bladder perforation after TURP.

Material And Methods: From 2013 to 2014, 220 patients received ESWL for kidney stones.
Introduction: In this study, we describe a new approach called the double-layer on and prepucial flap technique in order to prevent fistula or fissure development.
Material And Method: Twenty-seven patients with subcoronal hypospadias were enrolled. The prepared prepucial flap was divided into two equal parts.
Introduction: We investigated the monopolar and bipolar energy effects on prostate and correlated the results with the type of pathology, thus determining the relationship between tissue damage and the PSA level.
Material And Methods: One hundred and twenty four patients underwent TURP and according to the energy source, 2 groups were designed as monopolar (Group 1) and bipolar energy (Group 2). Hemoglobin and free and total PSA were measured preoperatively and 6 hours postoperatively, and differences were calculated.
Purpose: To audit the cost of laser versus pneumatic semirigid ureteroscopic lithotripsy and to analyze their relative initial outcomes and cost.
Methods: Hundred and eighty-seven patients who underwent semirigid ureteroscopic lithotripsy were analyzed retrospectively in terms of age and sex of the patients; location and size of the stones; the type of probe and ancillary equipment such as guide wire, basket catheter, JJ stent requirements; irrigation amount; operation time; the cost of the anesthesia and further treatments such as a JJ stent removal operation and shock wave lithotripsy requirements and their costs. Two groups were formed based on this type of lithotripters, pneumatic and laser lithotripsy.
