To evaluate the predictive value of some certain radiological as well as stone-related parameters for medical expulsive therapy (MET) success with an alpha blocker in ureteral stones. A total 129 patients receiving MET for 5 to 10 mm ureteral stones were evaluated. Patients were divided into two subgroups where MET was successful in 64 cases (49.61 %) and(More)
To evaluate protective effects of Tutukon®, a plant derived herbal product, on the development of rat urolithiasis model. A total of 45 rats were divided into three groups namely; Group 1 (control group; drinking water + zinc disk), Group 2 (0.5 % ethylene glycol [EG] to drinking water + zinc disk) and Group 3 (study group—0.5 % EG + Tutukon + zinc disk).(More)
ARTICLE INFO ______________________________________________________________ ______________________ Objective: We aimed to evaluate the possible effects of ureteroscopic procedures on the sexual function of both genders. Materials and Methods: A total of 102 sexually active cases (60 male, 42 female) undergoing ureteroscopic procedures were included in this(More)
To evaluate the potential protective effects of a calcium channel blocker (Verapamil) on the oxidative stress related changes with an emphasis on the antioxidant capacity of the kidneys an experimental study in rats was performed. A total of 44 rats have been included. Hyperoxaluria was induced in Group 1 by continuous administration of ethylene glycol(More)
With increasing incidence of pediatric urolithiasis over the past two decades, surgical management poses specific challenges for urologists because of the high risk of stone recurrence in this population. Keeping this in mind, management aims should be complete stone-free status, preservation of renal function, and prevention of stone recurrence. The(More)
OBJECTIVE To evaluate the possible effects of residual fragments on the health-related quality of life in patients undergoing extracorporeal shockwave lithotripsy for renal stones. PATIENTS AND METHODS Seventy-one patients with residual fragments were divided into 2 further groups; group 1 (n = 42; fragment size, ≤ 4 mm) and group 2 (n = 29; fragment(More)
This study aimed at evaluating the possible effects of residual fragments (RF) after shockwave lithotripsy (SWL) on the health-related quality of life (QOL) of the patients on a size-related basis. Eighty six patients with RF after SWL were divided into three groups: Group 1 (n:30 with fragments ≤2 mm), Group 2 (n:21 2–≤4 mm) and Group 3 (n:35 > 4 mm).(More)
OBJECTIVES To evaluate the emergency management of obstructing ureteral calculi with two different techniques (SWL and URS) with an emphasis on patients life quality. METHODS A total of 80 patients presenting with acute colic pain due to a single obstructing ureteral stone were treated within 24 hours following the onset of pain with two different(More)
This study aimed at evaluating the protective effects of a herbal medication (Tutukon) on the hyperoxaluria induced apoptotic changes and crystal deposition in renal tubular epithelium in rat model. 60 male wistar rats were divided into three different groups (each group n: 20). In Group I severe hyperoxaluria was induced by ethylene glycol (EG) (0.75 %)(More)
To evaluate the possible association between metabolic syndrome (MetS) and infectious complications after prostate biopsy. A total of 480 men underwent prostatic biopsy due to elevated prostate-specific antigen levels and/or abnormal digital rectal examination. Patients were divided into two subgroups with respect to the presence or absence of MetS.(More)
