Are predictive factors in sperm retrieval and pregnancy rates present in nonobstructive azoospermia patients by microdissection testicular sperm extraction on testicle with a history of orchidopexy operation?

The aim in this study is to evaluate predictive factors on sperm retrieval and pregnancy rates by microdissection testicular sperm extraction in non obstructive azoospermia patients with a history of orchidopexy operation. A total of 148 patients were included, and their medical files were evaluated. Data related to possible predictive factors on sperm retrieval and pregnancy rates such as age at orchidopexy operation, unilateral or bilateral presence of undescended testis before orchidopexy, testis volumes and hormone levels were statistically analysed.

Retrograde intrarenal surgery technique without using fluoroscopy and access sheet in the treatment of kidney stones.

Background/aim: In this study, we aimed to present our results on single-guidewire flexible ureteroscopy and retrograde intrarenal surgery without fluoroscopy and an access sheet, and to evaluate the efficacy and safety of this procedure retrospectively.

Materials And Methods: Our routine technique can be described as the evaluation of the ureter using a semirigid ureterorenoscope (URS), leading in the guidewire through the semirigid URS, pulling the semirigid URS back, inserting the flexible URS with the aid of the guidewire, inserting the laser probe through the flexible URS, and performing laser lithotripsy.

Results: Our study included 400 male and 198 female patients with a mean age of 36.

Evaluation of Prolidase Activity, Oxidative Stress, and Antioxidant Enzyme Levels in Testicular and Penile Tissues after Human Chorionic Gonadotropin Treatment in Rats by Predicting Infertility and Erectile Dysfunction.

Results: The mean duration of operation was 100.

Second pathways in the pathophysiology of ischemic priapism and treatment alternatives.

Objective: To evaluate the early therapeutic alternatives such as bosentan, an endothelin receptor blocker, theophylline, an adenosin receptor blocker, and a nonselective phosphodiesterase enzyme inhibitor, zinc protoporphyrin (ZnPP), a heme oxygenase 1 inhibitor, for the therapy of ischemic priapism in the rat models.

Methods: Twenty-four Sprague-Dawley rats were randomly divided into 4 equal groups: control group, ZnPP group, bosentan group, and theophylline group. Erection was provided by vacuum constriction method and maintained for 4 hours for achieving the priapism in all groups.

Potential relationship between BK virus and renal cell carcinoma.

The objective of the present study was to investigate the potential association between the presence of BK virus (BKV) DNA and mRNA and renal cell carcinoma and bladder transitional cell carcinoma. The formalin-fixed and paraffin-embedded tissue samples were obtained from 50 cancer patients with renal cell carcinoma, 40 cancer patients with bladder transitional cell carcinoma, 45 control patients with the benign renal pathology, and from another 25 control patients with benign bladder pathology. The samples were subjected to nested PCR for detection of BKV DNA and real-time reverse transcription PCR (real-time RT-PCR) for determining mRNA levels of BKV.

In vitro examination of effects of hyperprolactinemia and hypoprolactinemia on seminal vesicle contractions.

Objective: To investigate the contractile characteristics of the seminal vesicles in rats, in which hyperprolactinemia and hypoprolactinemia was induced by prolactin and bromocriptine administration.

Materials And Methods: A total of 24 Wistar albino rats were randomly divided into 3 groups: control group, hyperprolactinemia group, and hypoprolactinemia group. The rats in the control group were administered 0.

Abdominal hypertension characterised by severe haemodynamic changes as a complication of percutanous nephrolithotomy.

Percutanous nephrolithotomy (PCNL) was performed on a patient in a prone position. During the first hour of intervention, some unwanted haemodynamic complications arose, which included a decrease in systemic blood pressure, an increase in heart rate and an increase in peak inspiratory pressures. Owing to worsening of those unexplained haemodynamic abnormalities, surgery was terminated.

Effect of urinary incontinence and its subtypes on quality of life of women in eastern Turkey.

Objective: To determine the bothersomeness and effect on quality of life (QOL) of different types of urinary incontinence (UI) in married women living in eastern Turkey.

Materials And Methods: A total of 1049 married women was evaluated in the present population-based, cross-sectional study. QOL was assessed using a validated form of the Turkish version of the Incontinence Impact Questionnaire Short Form.

Evaluation of left renal vein entrapment using multidetector computed tomography.

Background: Nutcracker syndrome, also called left renal vein entrapment syndrome, is a cause of non-glomerular hematuria with difficulties in diagnosis. Multidetector computed tomography (MDCT) is a powerful tool to prevent unnecessary diagnostic procedures.

Purpose: To retrospectively determine the prevalence of nutcracker phenomenon and nutcracker syndrome seen in MDCT in consecutive patients.

Circulating soluble lectin-like oxidized low-density lipoprotein receptor-1 levels are associated with erectile dysfunction in patients without known coronary artery disease.

Aim: Endothelial dysfunction and microvascular damage are involved in the pathogenesis of erectile dysfunction (ED). Soluble lectin-like oxidized low-density lipoprotein receptor-1 (sLOX-1) is identified endothelial receptor for oxidized low-density lipoprotein (ox-LDL) that plays a pivotal role in ox-LDL-induced endothelial dysfunction. The purpose of the current study was to determine the association between sLOX-1 and ED in patients without known coronary artery disease (CAD).

Clinical and radiological evaluation of ejaculatory duct obstruction.

Ejaculatory duct obstruction (EDO) is a rare but surgically correctable cause of male infertility. With the advent and increased use of transrectal ultrasonography and magnetic resonance imaging, abnormalities of the ejaculatory duct (ED) related to infertility have been diagnosed more frequently. Recently, with the increased awareness of functional obstruction of ED, reports have been focusing on the diagnosis of partial or functional EDO.
