Compared with the standard technique, the number of percutaneous nephrolithotomy (PCNL) operations without a drainage catheter is increasing in recent years. In this prospective randomized study, we compared the morbidity of totally tubeless (tubeless and stentless) PCNL operations with the standard operation technique in a single center with a selected(More)
Intrauterine devices (IUDs) are currently one of the most popular reversible contraception methods used world wide. Uterine perforation is a rarely observed complication. The bladder is one of the organs that an IUD can migrate to because of its close proximity to the uterus. There are about 70 cases in the literature of IUDs that have migrated into the(More)
The aim of this study was to investigate the effectiveness and reliability of the micro-percutaneous nephrolithotomy (PNL) method for the management of kidney stones. We performed a retrospective analysis of 136 patients (140 renal units) who underwent micro-PNL for renal stones between September 2011 and February 2013 in four referral hospitals in Turkey.(More)

PATIENTS AND METHODS A total of 90 patients were divided into two subgroups. The first group had ABS applied during the intervention, whereas the control group underwent regular tubeless(More)
An increased pretreatment neutrophil–lymphocyte ratio (NLR) is associated with poor prognosis in colorectal, gastric, and ovarian cancer; malignant mesothelioma; and renal cell carcinoma. The present study aims to define the predictive value of preoperative peripheral blood count NLR in non-muscle-invasive bladder cancer (NMIBC) and muscle-invasive disease(More)
The objective of the study was to present the clinical and operative effects of two types of anesthesia on micro-percutaneous nephrolithotomy (“microperc”). We retrospectively reviewed 116 patients who underwent microperc between August 2011 and September 2013. Patients were sorted into one of the two groups according to the type of anesthesia received:(More)
PURPOSE To investigate the effects of vardenafil HCl on testicular germ cell apoptosis and the expressions of iNOS and eNOS within the bilateral testes after unilateral torsion/detorsion (T/D) in a pig model. METHODS 12 male pigs weighing 50-55 kg were divided randomly into three groups (n = 4). Sham operation and T/D was performed in groups 1 and 2,(More)
OBJECTIVE The objective is to compare the analgesic effects of diclofenac, acetaminophen, and acupuncture in urolithiasis-driven renal colic pain relief. METHODS Renal colic patients were divided randomly into 3 groups. Patients in group I (n = 40) were treated with intravenous acetaminophen, those in group II (n = 41) with acupuncture, and those in group(More)
